Embodiment 1

[0027] figure 1 It is a system structure diagram of an embodiment of the tracked vehicle steering system of the present invention.

[0028] The tracked vehicle steering system includes: two front drive motors 3a and 3b (3a is a left front drive motor, 3b is a right front drive motor), two rear drive motors 3c and 3d (3c is a left rear drive motor, 3d is a right rear drive motor) Motor), two front wheels 1a and 1b (1a is left front wheel, 1b is right front wheel), two rear wheels 1c and 1d (left rear wheel, 1d is right rear wheel), two front drive reducers 2a and 2b (2a is the left front drive reducer, 2b is the right front drive reducer), two steering coupling devices 8a and 8b (8a is the left steering coupling device, 8b is the right steering coupling device), a steering motor 10; the left front drive motor The output shaft of 3a is connected to the left front wheel 1a through the left front drive reducer 2a, the output shaft of the right front drive motor 3b is connected to...

Embodiment 2

[0046] The invention also discloses a tracked vehicle steering method, which is applied to the above tracked vehicle steering system;

[0047] This steering method includes:

[0048] When the required power of the outer wheel is less than or equal to the maximum output power of the front drive motors 3a and 3b and the rear drive motors 3c and 3d corresponding to the outer crawler belt, control the two electromagnetic brake clutch devices 13 to turn the corresponding steering motor 10 The connection between the output shaft and the corresponding steering motor shaft gear 12 is disconnected, so that the steering motor 10 stops driving the steering motor shaft gear 12. When the required power of the outer wheel was greater than the maximum output power of the front drive motors 3a and 3b and the rear drive motors 3c and 3d corresponding to the outer crawler belt, the inner electromagnetic brake clutch device 13 was controlled to connect the corresponding steering motor 10 output ...

Abstract

The invention discloses a tracked vehicle steering system and method. The steering system is a four-wheel independent drive system, two front wheels are driven by a drive motor and a reducer, two rearwheels are driven by a drive motor and a steering coupling device, and the power of the two steering coupling devices is supplemented by a steering motor. The system and method of the invention solvethe problem of insufficient torque when steering at low speed and small radius under the condition of small motor volume by means of four-wheel independent driving, and solve the problem that the motor power of the outer motor is low when steering at high speed and large radius by means of steering motor to carry out power supplement to the steering coupling device.

Description

technical field [0001] The invention relates to the technical field of tracked vehicles, in particular to a tracked vehicle steering system and method. Background technique [0002] Tracked vehicles achieve the purpose of steering by making the two sides of the track have a speed difference through the steering mechanism, which is fundamentally different from wheeled vehicles. Tracked vehicles have excellent driving ability under harsh working conditions and have good maneuverability and off-road performance. Now they are widely used in military, civil, agricultural and other fields. With the large-scale application of tracked vehicles and the demand for electrical energy in the on-board electrical and electronic systems of tracked vehicles in the future, the electric drive technology of tracked vehicles has become an important development direction. [0003] At present, the widely used electric transmission drive mode is mostly driven by dual motors independently, that is,...
