A double-sided motor-driven tracked vehicle steering system

Abstract

The invention provides a bilateral motor-drive tracked vehicle steering system which comprises a control system, a power system and a mechanical system. The mechanical system comprises a driving motor, a brake and a speed reducer, wherein the speed reducer is connected with a vehicle driving wheel. The mechanical system further comprises a steering motor controller, a steering motor, a controllable differential, a clutch and a coupler, wherein the steering motor controller, the steering motor, the controllable differential, the clutch and one input end of the coupler are connected sequentially, another input end of the coupler is connected with the driving motor, the output end of the coupler is connected with the brake, and the steering motor controller, the controllable differential and the clutch are further connected with the control system. The steering motor is arranged in the mechanical system, torque supplied by the steering motor and the driving motor is coupled through the coupler, the maximum power of the driving motor can be reduced, and the power of the driving motor is fully utilized.

Description

technical field [0001] The invention relates to a double-sided motor-driven crawler vehicle steering system, which belongs to the technical field of vehicle steering. Background technique [0002] The problem of vehicle steering is the core issue in the driving theory of tracked vehicles, and the flexibility and controllability of steering are important indicators for evaluating the maneuverability of tracked vehicles. Tracked vehicles use the steering mechanism to obtain different speeds for the tracks on both sides to achieve steering, which is fundamentally different from the steering principle and steering mechanism of wheeled vehicles. The steering methods of tracked vehicles are generally divided into steering clutch-brake steering, mechanical dual power flow steering, hydraulic mechanical differential steering and electronically controlled differential steering. Tracked vehicles independently driven by double-sided motors usually use electronically controlled differe...
