Abstract

The invention discloses a combined type suspension system for a tracked vehicle. The vehicle comprises a vehicle body, twelve loading wheels and twelve balance elbows, wherein one end of each balance elbow is hinged with the vehicle body, and the other ends of the balance elbows are hinged with the loading wheels; structures on two sides of the vehicle body are symmetrical, and a first single-chamber hydro-pneumatic spring, a first double-chamber hydro-pneumatic spring, a second single-chamber hydro-pneumatic spring, a second double-chamber hydro-pneumatic spring, a third double-chamber hydro-pneumatic spring and a third single-chamber hydro-pneumatic spring are mounted between the balance elbows on two sides and the vehicle body from front to back sequentially. Compared with a single-type hydro-pneumatic suspension system, the combined type suspension system can improve the riding comfort of a tank on the off-road pavement by 30% or above on the premise of the vehicle speed of 20 m / s.

Description

technical field [0001] The invention belongs to the technical field of vehicle engineering design, in particular to a composite crawler vehicle suspension system. Background technique [0002] Ensuring that tracked vehicles run smoothly and quickly on off-road surfaces is of great significance for improving the comfort of drivers and passengers, the traction of vehicles, the service life of vehicle parts and the accuracy of shooting in combat. For this reason, suspension systems and damping devices are generally installed on the road wheels of tracked vehicles, so as to reduce the influence of ground unevenness on vehicle driving stability. Tracked vehicles, especially main battle tanks, have a heavy body weight, so 5-7 road wheels are generally installed on each side of the body to carry the weight of the body and the dynamic load generated when the vehicle is running fast. In addition, the vehicle sometimes needs to adjust the attitude of the vehicle body during driving, ...
