Abstract

The invention relates to a steering link stroke protection device of a tracked vehicle. The steering link stroke protection device comprises a cushion chamber and a fine shaft, wherein an end nut is arranged at one end of the cushion chamber, and the fine shaft penetrates through the nut; a core sleeve which is fixed with springs is arranged on the fine shaft located in the cushion chamber. Compared with the prior art, the steering link stroke protection device of the tracked vehicle, provided by the invention, has the advantage that link stroke protection for a steering pump motor servo system pull-arm return stroke during the overloaded steering of the tracked vehicle or the low-speed steering of an engine of the tracked vehicle is achieved.

Description

technical field [0001] The invention relates to a travel protection device, in particular to a travel protection device for a steering link of a crawler vehicle. Background technique [0002] When the steering overload motor of the variable pump quantitative motor system for tracked vehicles and steering has no output speed, the volumetric efficiency of the pump motor system is low, and the pump motor generates a lot of heat. The pull arm of the pump motor system and the swash plate of the pump motor system return through the servo mechanism of the pump motor system. , can play a role in reducing pump displacement and reducing energy consumption. However, the pump motor system servo backstrokes the connecting rod, which involves the protection of the connecting rod travel caused by the backstroke. When the vehicle turns when the engine is at low speed, the engine output torque is small, but if the pump works in a large displacement condition, the engine output torque is lar...
