Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the power of the single-side motor is too large when the electronically controlled low-speed steering torque is too large for the double-side motor-driven crawler vehicle, and the power of the single-side motor is too large for medium-speed steering and high-speed steering. Stepless steering is difficult, and a dual-motor coupling drive tracked vehicle steering system that can reduce the power of one side motor and realize stepless steering is designed

Embodiment Construction

[0015] The invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0016] The dual-motor coupling-driven crawler vehicle steering system provided by the present invention works on the following principle: when steering at low power (when the power required for steering is less than the maximum power of the driving motor), electronic differential stepless steering is used, that is, the driving The form of energy provided by the motors respectively; when turning with high power and turning on difficult roads with small radius (when the power required for steering is greater than the maximum power of the driving motor), by engaging the central electromagnetic clutch, the torque of the motors on both sides is realized by coupling turn. The conversion of the two modes in the present invention is realized through the connection and disconnection of the central electromagnetic clutch. The design of this steering sy...

Abstract

The invention provides a double-motor coupled driving tracked vehicle steering system, which comprises a control subsystem, a power subsystem and a mechanical subsystem, wherein the mechanical subsystem comprises two drive motors, a clutch, a brake, a controllable coupler, an electromagnetic clutch friction disk braking device and a central electromagnetic clutch; the brake is connected with driving wheels of a tracked vehicle; the central electromagnetic clutch is connected with the controllable coupler through the electromagnetic clutch friction disk braking device; and the controllable coupler is further connected with the drive motors and the clutch respectively. By adopting the controllable coupler, the two motors are coupled together to supply energy to the driving wheels of the vehicle, namely the motor on one side, which is steered by relatively small torque, is used for supporting the motor on the other side, which is steered by relatively large torque; due to the distribution mode, the requirement on the power of the drive motor on the single side can be reduced greatly; and therefore, energy of the drive motors can be used fully, and electrodeless steering is realized.

Description

technical field [0001] The invention relates to a vehicle steering system, in particular to a dual-motor coupling-driven crawler vehicle steering system. Background technique [0002] 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 motors on both sides usually use electronically controlled differential steering, such as Zhai Li, Su...
