Method for controlling tracked vehicle to go straight and to turn, steering device and stepless steering system

Abstract

The invention discloses a method for controlling a tracked vehicle to go straight and to turn, a steering device and a stepless steering system. The tracked vehicle is controlled to go straight and to turn by changing the transmission connection relation among a power input shaft, a left output shaft and a right output shaft. The method comprises the following steps that 1) when the tracked vehicle is controlled to turn, a left meshing gear on the left output shaft is meshed with a right meshing gear on the right output shaft to enable the two output shafts to be in transmission connection, and the power input shaft is selectively made to be in meshing transmission connection with one of the two output shafts through a gear according to the turning direction of the tracked vehicle; 2) when the tracked vehicle is controlled to go straight, the left meshing gear on the left output shaft is separated from the right meshing gear on the right output shaft, and the power input shaft is made to be respectively in meshing transmission connection with the two output shafts though gears. After a straight running mechanism breaks down or a steering brake mechanism breaks down, the tracked vehicle can be controlled to go straight through the steering device, and the tracked vehicle is guaranteed to walk normally.

Description

technical field [0001] The invention relates to a method for controlling straight running and steering of a crawler vehicle, a steering device and a stepless steering system. Background technique [0002] With the development and progress of science and technology, the market puts forward more and more requirements for the steering system of tracked vehicles. It is not only required that the steering system can control the steering of tracked vehicles, but also need to be able to control the tracked vehicles to drive in a straight line. [0003] A utility model patent with the authorized announcement number CN20243919U discloses a stepless steering system for tracked vehicles that can control the steering of the tracked vehicle and can also control the straight travel of the tracked vehicle. The device and the left converging planetary row and the right converging planetary row, the shunting mechanism includes the shunting planetary row, and the shunting planetary row is com...
