Abstract

The invention discloses a dual power flow crawler vehicle drive and steering system, including a control system, a power system, a linear drive system, a steering drive system and a gear pair system; the power system provides power for the linear drive system and the steering drive system, and the control system passes through Control the linear drive system and then control the gear pair system to realize the linear drive of the vehicle. The control system controls the steering drive system and then controls the gear pair system to realize the steering drive of the vehicle; the linear drive system includes the first hydraulic transformer, one-way valve group I and two-way quantitative pump / Motor, the steering drive system includes the second hydraulic transformer, one-way valve group II and two-way quantitative motor. The invention can realize the dual stepless speed regulation function of the driving and steering system of the crawler vehicle, and has the advantages of compact structure and braking energy recovery.

Description

technical field [0001] The invention relates to the technical field of crawler vehicles, in particular to a driving and steering system of a crawler vehicle with dual power flows. Background technique [0002] At present, the tracked vehicle steering system has roughly gone through the stages of steering clutch-brake, mechanical dual power flow steering system and hydraulic mechanical dual power flow differential steering system. The clutch-brake needs to rely on the friction between the friction elements to realize it, it is difficult to obtain an accurate and stable turning radius, and there are disadvantages such as low transmission efficiency, poor working reliability, low service life, and limited number of turning radii. The steering performance of the mechanical dual power flow steering system is greatly improved compared with the single power flow steering mechanism, but its steering radius is still graded; the overall structure of the steering mechanism is scattered...
