Continuously variable steering mechanism for tracked vehicle

Abstract

The invention relates to a continuously variable steering mechanism for a tracked vehicle. The continuously variable steering mechanism for the tracked vehicle comprises a differential mechanism, a right transmission shaft, a left transmission shaft and a continuously variable transmission used for regulating rotational speeds of the right transmission shaft and the left transmission shaft; the differential mechanism is connected with a left half shaft and a right half shaft; the right half shaft of the differential mechanism is in linkage matching with the right transmission shaft; the right transmission shaft rotates to drive the right half shaft of the differential mechanism to rotate; the left half shaft of the differential mechanism is in linkage matching with the left transmission shaft; the left transmission shaft rotates to drive the left half shaft of the differential mechanism to rotate; and the rotational speed ratio of the right half shaft of the differential mechanism and the right transmission shaft is equal to that of the left half shaft of the differential mechanism and the left transmission shaft. With adoption of the technical scheme, the invention provides the continuously variable steering mechanism for the tracked vehicle, in which the rotational speeds of the left and right half shafts of the differential mechanism are continuously and accurately regulated through the continuously variable transmission, thus accurate turning of a track is realized, the high-speed driving safety of the tracked vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of tracked vehicle steering, in particular to a continuously variable steering mechanism of a tracked vehicle. Background technique [0002] The steering of tracked vehicles is different from the steering of wheeled vehicles. The steering of wheeled vehicles only needs to control the angle of the wheels, while the steering of tracked vehicles currently used basically uses brakes to control the deceleration of one side of the track, while the other The track on one side operates normally to achieve steering. However, with this control method, when the tracked vehicle is running at high speed, if the track on one side is stopped, it is easy to cause a rollover accident, and the risk factor is high; moreover, it is controlled by manual braking. , low turning accuracy. Contents of the invention [0003] Purpose of the present invention: In order to overcome the defects of the prior art, the present invention ...
