Abstract

A hydraulic mechanical transmission with the auxiliary steering function comprises an input shaft, a mechanical transmission mechanism, a hydraulic transmission mechanism, a double-planet-row mechanism, a single-planet-row mechanism, a left driving device and a right driving device. The input shaft is connected with the mechanical transmission mechanism and the hydraulic transmission mechanism; the mechanical transmission mechanism and the hydraulic transmission mechanism drive the double-planet-row mechanism at the same time; the double-planet-row mechanism is connected with the single-planet-row mechanism; the double-planet-row mechanism drives the right driving device; and the single-planet-row mechanism drives the left driving device. The hydraulic mechanical transmission has the beneficial effects that straight driving and steering of a vehicle are achieved through cooperation of the mechanical transmission and hydraulic transmission; the hydraulic mechanical transmission can be used as a straight driving brake of the vehicle and also can be used as an adjusting device in the steering process of the vehicle, and the steering performance is excellent; in the straight driving process, efficient transmission is achieved; and in the steering process, stepless steering is achieved, and the steering radius can be precisely controlled according to different curve roads.

Description

technical field [0001] The invention relates to a hydraulic-mechanical gearbox, in particular to a hydraulic-mechanical gearbox with an auxiliary steering function. Background technique [0002] The hydraulic mechanical continuously variable transmission (HMT) is composed of a hydraulic speed regulating mechanism, a mechanical speed changing mechanism and a diverting and converging mechanism. It is a new transmission form in which the hydraulic power flow and the mechanical power flow are connected in parallel. The combination of transmission and mechanical transmission realizes stepless speed change. [0003] There are three types of steering mechanisms for wheeled vehicles: axle steering, wheel steering and articulated steering: [0004] 1. The steering action of the articulated vehicle is similar to the axle steering, that is, the wheels have no steering action and the hydraulic or pneumatic mechanism is used to push the articulated part of the vehicle to turn the vehicl...
