plus, A-type double-arm front suspension state does not have an independent safety space in front of the drive system, LYT2021 wheeled parachute assault vehicles only have two prototype drive capability. Relative LYT2021 parachute assault vehicles wheeled production version of the 4WD mode, retains the transverse BN492QB prototype engine, speed manual transmission and “vertical cross-change” when the torque converter, not set the “2 in 1” before 4 drive module. According to participate in mass production LYT2021 wheeled parachute assault vehicles friend suggested that early development of the prototype of the university, after transferred to Wuhan Lingyun Technology Co., Ltd. and the front and rear suspension and drive system has been improved, most notably facelift the installation of the front differential and independent suspension drive axle for mounting “2 in 1” and the rear drive module drive axle make lightweight dress inclined semi-independent suspension trailing arm sufficient space.
Of course, the entire vehicle using the same material the same large diameter pipe rack, increase ground clearance, improved ergonomics of the exterior and interior, is LYT2021 wheeled production version parachute assault vehicles are different prototype differences.
In addition, the 200X years later, Wuhan Lingyun Technology Co., Ltd. of LYT2021 wheeled parachute assault vehicles were 2nd technical improvements for the factory to bid new projects. For powertrain, transmission and four-wheel drive system was upgraded to increase flexibility while continuing to reduce weight (due to failed bid without mass production).
a huge difference between the vehicle suspension and four-wheel drive system prototype and the production version of the paratroopers assault from LYT2021 wheeled see, as the People’s Liberation Army airborne combat airdrop just need the equipment, the primary demand is intact and high ground operations Mobile assault performance, as the type of protection and improvement of the potential of the state belong to the second best. This airdrop airborne equipment research and development strategy has been extended so far back.

Car gun 09 relative to the set only after the non-independent suspension made of leaf springs and the bridge resulting in the overall emission gun is set in group 2 the plow, the recoil is absorbed, so that the poor overall stability, after multiple rounds of shooting own position change occurs resulting in reduced shooting accuracy.
Yes! Loading height-adjustable hydraulic damping system 6 drive vehicles, as PCL-181 type car 155mm gun, brings more than just technology to enhance the quality, but also firepower projection “opposite” attack, firepower “to the point “attack” multiplier. ”
on the 
The picture shows the PCL-181 type hydraulic shock absorber 155mm artillery vehicle system 3 sets all bottoming drive axle, and a pressure valve fully latched, a partial 30 degrees counter-fire close-up shooting. At this time a downward and bias the firing recoil, is transmitted to the ground through the plow and the vehicle body in the two groups. Since a completely rigid connection with hydraulic shock absorbers to the vehicle body (noBuffer space), the deflection shooting recoil generated by low consumer better platform stability, so that the PCL-181 type 155mm cannon on-board only with remote fire support capability, but also have the ability to direct fire at close range attack enemy’s armored track.
I have something to say:
recovered in the past 70 years, the PLA armored tank technology and equipment development, first introduced Soviet-style T-series tanks, ZIL series of heavy-duty off-road trucks, followed by simultaneous localization self-innovation. 1970 main battle tanks proposed “three machines three-solution” program, although at that time out of the actual carrying capacity of China’s auto industry and other supporting industries, but for this purpose the continuous application of technologies developed in the later 2000s. 
Today we see the People’s Liberation Army equipped with the latest technology weapon, the full introduction of height-adjustable hydraulic damping and shock absorption technology at the same time the air bag, and no longer limited to 4×4,6×6 8×8 type vehicles. We have to load bigger, richer application scenarios, carrying “big country weighing equipment,” the 10×10 series of super-heavy vehicle adaptation.
Thus, the trial out of the 199X in LYT2021 wheeled prototype parachute assault vehicles, not accidental in the “butterfly effect” inadvertently produced, but Chinese universities and research institutes in the structure of the new era, FAW, Dongfeng, Shaanxi gas, heavy truck, heavy truck inevitable result of the north, and many domestic Institute and co-operation of specialized institutions.
