Title:
TURNING SPEED CONTROL DEVICE FOR TRACKED VEHICLE
Document Type and Number:
Japanese Patent JP2589052
Kind Code:
B2
Abstract:

PURPOSE: To obtain a small turning radius at a turn to the right or the left at the time of high-speed travel by holding the maximum number of revolution of a steering motor and at the same time decreasing a vehicle speed when the number of revolution of the steering motor exceeds the displacement position of reaching the maximum number of revolution of the steering motor.
CONSTITUTION: In a tracked vehicle which is provided with a steering motor 80 for turning a vehicle body to the right and the left by driving a right and a left crawler belts which are stretched on a sprocket 6 so as to produce a relative travelling difference, it is provided with a control part 96 for controlling the number of revolution of the steering motor 80 in accordance with the displacement of a steering lever, which is detected by a steering lever displacement detection device 94. When the turning radius of a vehicle body is made small by driving the respective crawler belts so as to produce a relative travelling difference and the number of revolution of the steering motor exceeds the displacement position of reaching the maximum number of revolution of the steering motor 80, the steering motor 80 is made to hold the maximum number of revolution and at the same time the vehicle speed is decreased in accordance with the displacement of the steering lever as far as the maximum displacement position of the steering lever.
