Abstract

The invention relates to a two-track-driving tractor proportional steering transmission method. A two-track-driving tractor is powered by an engine, and power is divided into two ways through a transmission and a proportional differential steering device to drive a left track and a right track to move; and an electric control unit is adopted to receive a corner signal and a tractor speed signal of a steering wheel of the tractor, by controlling a proportional solenoid valve controller to work, the proportional differential steering device controls the corresponding corner relation of a wobble plate of a variable pump and the steering wheel of the tractor through an electric control system, and thus a constant displacement motor has stepless speed change power output, and adjusts a worm wheel of the proportional differential steering device by controlling a worm so as to achieve electric proportional differential steering of the tracked tractor. The two-track-driving tractor proportional steering transmission method has the characteristics of high steering precision, stable steering movement rule and the like.

Description

technical field [0001] The invention belongs to the technical field of mechanical transmission, and in particular relates to a proportional steering transmission method of a tractor driven by two crawlers. Background technique [0002] At present, crawler tractors mainly have three structural forms: four-track, wheel-track and two-track. Among them, the four-track mainly uses the deflection body hinge point to realize the steering of the crawler tractor, and the wheel track adopts the deflection front wheel steering and the deflection body hinge point. However, due to the unique structural characteristics of the two-tracked vehicle, the steering can only be realized by using the differential speed of the two-sided track. At present, the steering methods of two-tracked vehicles mainly include single power flow, dual power flow and other steering forms. Among them, the dual power flow steering has high efficiency and is widely used because the power transmission is not interru...
