Torsion suspension, which is the dominant suspension system for tanks after Christie's suspension. The Christie suspension system, while good, has several significant flaws.

It occupies too much area, which reduces the internal space of the tank. The tank's bomb load, fuel tank, and driver crew had to be reduced. Second, its damage rate is relatively high, and it is difficult to repair.

These are the great shortcomings of the Christie suspension system, so in the middle and late stages of World War II, the Christie suspension system withdrew from the ranks of tank suspension systems, and was replaced by the torsion bar suspension system proposed by Tu Qianjun.

Of course, the Christie suspension system also has benefits that torsion bar suspension does not have. For example, it can adjust the direction of various corners, torques and even wheels...... Wait a minute. In comparison, the torsion bar suspension is much more monotonous.

Not only is the shock absorption not as effective as the Christie suspension system, but it is also functionally simple. It can only be used to walk backwards, backwards, up, down, left and right. (Look at our current tanks, as well as American tanks or tracked bulldozers, excavators, etc., which are suspended with torsion rods)

The principle of Christie suspension is to change the axis of motion of the spring from vertical to horizontal with a double-arm crank, while torsion bar suspension replaces the spring with the torsion bar and lever principle. The advantage of a torsion bar is that it makes better use of space in the car body and is sturdy and durable.

This plan was hidden by Tu Qianjun himself. It is only assembled in the new car factory and stockpiled. And those commanders who have formed production efficiency are naturally producing tanks for the USSR!

Tu Qianjun is working hard, and the Nanjing government is not idle. Yang Ziren has run away to northern Shaanxi, and Jiang Zhongzheng will naturally not give up! It is obviously inappropriate to mobilize heavy troops to northern Shaanxi. So his eyes fell on the silent Zhang Xueliang.

In September 1935, Jiang Zhongzheng set up the Northwest Bandit Suppression General Headquarters in Xi'an, appointed himself commander-in-chief, appointed Zhang Xueliang as the deputy commander, and transferred the Northeast Army to Shaanxi, Gansu and Chi.

After Zhang Xueliang was silent for a long time, he chose to obey. He dispatched his troops to the Northeast Army directly to the area controlled by the Reds. tried to exterminate Yang Ziren and others.

In early October, in the Battle of Laoshan of the Northeast Army, Wang Yizhe's 2 regiments and division headquarters of the 110th Division of the 67th Army were annihilated, and the division commander He Lizhong was killed. The regiment commander, Pei Huancai, was captured.

At the end of October, in the Battle of Yulin Bridge of the Northeast Army, the 107th Division and the 619th Regiment were all annihilated, and the regiment commander Gao Fuyuan and many soldiers were captured. In November, the 109th Division, the most elite and well-equipped division of the Northeast Army, was defeated in the Battle of Zhiluozhen.

The division commander Niu Yuanfeng ordered the adjutant general to kill himself, and then the entire 109th Division was defeated. With only more than 800 casualties, Yang Ziren and others killed, wounded, and captured more than 6,000 soldiers of the elite 109th Division of the Northeast Army. However, the prisoners were released under the maneuvering of the Wehrmacht.

Tu Qianjun who learned the news. All that can be done is a deep sigh. He knew that now Zhang Xueliang was almost cornered, and the non-resistance generals of 918 had ruined his reputation.

If it weren't for the fact that there were still a large number of Northeast Army loyal to him, perhaps Jiang Zhongzheng would have removed him from his post a long time ago! Although most of the Northeast Army was withdrawn to Guannai, the structure was basically intact. At the same time, the weapons are not bad.

Jiang Zhongzheng didn't dare to deal with Zhang Xueliang easily, you must know that now the Gui and Yue departments are still eyeing each other! If you are not careful, you may lose the whole game.

Then Tu Qianjun asked him to find Zhang Xueliang as an intermediary and proposed not to continue the war with the red. Zhang Xueliang was silent for a long time and nodded in agreement.

And at the same time. The Red Convened, the Wayaobao Conference, and established the policy of the anti-Japanese national united front.

In January 1936, Yang Ziren, Wu Hao and others jointly issued the "Letter to All Officers and Soldiers of the Northeast Army for Willing to Join with the Northeast Army to Resist Japan". At this time, although the Red did not receive weapons support from the Wehrmacht, the various material supplies along the way allowed them to reduce a large number of non-combat attrition.

Of course. This was not given to them by the Wehrmacht for nothing, either. Along the way, the red fight against local tyrants, the division of land, etc., harvested a lot of funds, which were basically handed over to the four places and deposited in the Fengtian Bank opened by the three eastern provinces.

When they arrived in northern Shaanxi, the money was sent to them from Mongolia. With funds in hand and weapons captured from the Northeast Army, the historical crusade naturally did not start again.

But if they don't launch, it doesn't mean that Jiang Zhongzheng will die down, and after learning that Zhang Xueliang suffered heavy losses and the attack slowed down, Jiang Zhongzheng was anxious! repeatedly urged Zhang Xueliang to continue to suppress bandits, but Zhang Xueliang also matured at this time.

After several defeats, he realized that he was not facing a "rogue". And Nanjing's lack of mention of replenishing guns, ammunition and soldiers also made him cold!

Therefore, on the surface, he expressed obedience, but in fact he did not continue the war with Yang Zi and let them continue. On the contrary, with the activities of the Wehrmacht, a temporary ceasefire was negotiated with the Reds. And began contact.

After all, Jiang Zhongzheng did not come to Xi'an to supervise the suppression of bandits, because he discovered the changes between the two Guangzhou. This change became extremely obvious after the Fujian incident. Dai Li's report: After the incident in Fujian, the number of telegrams between the two Guangxi provinces increased significantly!

For things that threaten his position, Jiang Zhongzheng has always been extremely sensitive! Especially the Yue and Gui families, these two sides are not less against him! Therefore, he could only endure it and deal with the people on both sides first.

With Dai Li's efforts, all kinds of money are scattered! Zhang Qun and others also secretly dispatched. Go to Guangdong and Guizhou to secretly buy generals!

In fact, Chen Jitang and Li Zongren were forced to resist Jiang Zhongzheng. At the end of 1935, Chen Jitang sent people to Nanjing to report on his work. Chiang Zhongzheng revealed to him the principles and policies for resolving the Xingui faction, and asked Chen Jitang to cooperate and expel all anti-Chiang forces in Guangdong.

When Chen Jitang learned about it, he was very suspicious, believing that once the new Gui system failed, the Cantonese system could not avoid the fate of being annexed by Jiang Zhongzheng. Therefore, he took the initiative to contact the Xingui department and oppose Jiang together.

But what Chen Jitang didn't expect was that he and Li Zongren had a lot of Jiang Zhongzheng people around him. These situations naturally fell in the eyes of Jiang Zhongzheng! Jiang Zhongzheng couldn't help sneering, since he didn't know how to lift, let's get out of here.

At the beginning of 1936, Li Zongren, the leader of the Xingui faction, publicly published the "Scorched Earth War of Resistance" to condemn Japanese aggression; attacking the "inaction" of Chiang Zhongzheng's central government at that time caused China to enter a state of "neither death nor life"; It was declared that the whole of China must "scorched earth to resist the war".

Subsequently, Li Zongren and Bai Chongxi published articles many times, attacking the inaction of the Central Committee of Chiang Zhongzheng against Japan, and claiming that the local powerful factions were willing to jointly send troops to resist Japan!

Naturally, the Nanjing government sent a group of people to conduct a polemic. He claimed that the central government insisted that "if you want to conquer the outside world, you must first secure the interior," and insisted that only after reunifying the whole country could it go all out to counter Japan's aggression.

When the debate between the two sides was in full swing, an accident happened! In January 1936, Hu Hanmin, a veteran of the Kuomintang, an anti-Chiang faction, and the nominal leader of the Cantonese faction, suddenly died of a sudden illness!

Jiang Zhongzheng believed that the time had come, and without hesitation, he took advantage of Hu Hanmin's death to immediately announce five suggestions:

First, cancel the semi-** status of the two Guangzhous; second, to send someone to replace Hu Hanmin's position in the Guangdong Provincial Government and reorganize the Guangdong Provincial Government; Third, the former Cantonese figures were willing to work in Nanjing at will, and those who did not want to be funded by the central government went abroad for investigation.

Fourth, the commanders of all divisions of the Guangdong Army are uniformly appointed by the Military Commission; Fifth, the Guangdong currency will be abolished and the legal tender will be unified. These five proposals are intended to bring power in Guangdong back to the central government.

As soon as the suggestion came out, it immediately aroused a strong reaction from Chen Jitang and Li Zongren. Chen Jitang was unwilling to sit still, so he immediately contacted the Xingui faction and decided to jointly send troops to the north to oppose Chiang.

At the same time, groups of people are also coming and going in Guangdong and Guangxi. These people are secret agents from the Fourth Division of the Three Eastern Provinces. Compared to Dai Li, they are more professional. Because their trainer is the Tu Qianjun who has been secretly organized in later generations!

Because of his own particularity, Tu Qianjun has no less contact with those hidden personnel. And the reason for his work has also taught him some of these means and methods - you know! He's not just a warrior! In fact, in many cases, it also has latent ability training!

Therefore, although it has not been established for a long time, its experience, radiation and management ability are much higher than Dai Li and others! The Hongmen incision code from Geyuetan allows them to be like fish in water everywhere!

The protection of the offices of the three eastern provinces on the bright side has made their safety factor much higher. All parties are operating in secret, and all kinds of forces are intertwined! And by "suppressing bandits" Jiang Zhongzheng's forces have entered the southwest region!

This also made Long Yun and others in Yunnan suspicious of this. The defeat of Wang Lie in Guizhou, they watched it. Jiang Zhongzheng's method made them not feel cold, and they basically did not contribute to the red work of the transit.

This gave Jiang Zhongzheng no excuse to enter Yunnan, but the Central Army made Long Yun feel like a sharp edge in Guizhou! And the Central Army's general order to take back Liangguang also made him feel cold!

This is to be cleaned up thoroughly! If Nanjing succeeds, will it be his turn next?! At this time, Gu Zhutong led Xue Yue and other troops to slowly approach from Guizhou! It seems to be calm, but in fact it is surging!

In Japan, after a series of transformations, the production of new fighters has been able to reach a monthly output of 600 aircraft. At the same time, Mitsubishi Heavy Industries also came up with its own tank model - the Type 97 tank!

This tank is a new type of tank developed based on the existing ** tank. The Korean war made Japan feel the importance of tank firepower! Therefore, the new tank is equipped with a 57mm Type 97 gun and two Type 97 vehicle-mounted heavy machine guns.

At the same time, a 12-cylinder air-cooled diesel engine with a power of 170 hp was used, which was located at the rear of the body. The vehicle has a maximum speed of 38 km/h, with the driving wheels in front, and the power is transmitted to the gearbox and parallel at the front of the hull through a long propeller shaft.
