Abstract

The invention relates to a two-track drive tractor proportional steering device. The two-track drive tractor proportional steering device at least comprises an engine, a vehicle frame, a clutch, tracks, a transmission, a proportional differential steering device and an electronic control system. The proportional differential steering device is integrated on the transmission. The transmission is installed on the engine through the clutch. The engine, the clutch, the transmission, the proportional differential steering device and the electronic control system are installed on the vehicle frame.The tracks are installed on output shafts on the two corresponding sides of the proportional differential steering device. The proportional differential steering device controls a corresponding cornerrelation between a swash plate of a variable pump and a steering wheel of a tractor through the electronic control system, so that a constant displacement motor has infinitely variable speed power output, the constant displacement motor adjusts worm wheels of the proportional differential steering device through control of a worm, a tracked vehicle steers, and the two-track drive tractor proportional steering device has the beneficial effects of being high in steering accuracy, regular and stable in steering motion and the like.

Description

Technical field [0001] The invention belongs to the technical field of mechanical transmission, and specifically relates to a two-crawler-driven tractor proportional steering device. Background technique [0002] At present, crawler tractors mainly have three structural forms: four-tracks, wheel-tracks and two-tracks. Among them, the four-tracks mainly use the pivoting body articulation point to realize the steering of the crawler tractor, and the wheel crawler adopts the deflection front wheel steering and the deflection body articulated point steering. Because of its unique structural characteristics, the two-track vehicle can only use the method of differential speed on both sides to realize steering. At present, two-track vehicle steering methods mainly include multiple steering modes such as single power flow and dual power flow. Among them, dual power flow steering has high efficiency and is widely used because power transmission is not interrupted during the steering proce...
