The invention relates to a pure electric sanitation vehicle and a vehicle steering system. The vehicle steering system includes an electronically controlled hydraulic power assist system, a steering wheel, a steering wheel shaft, an eddy current resistance device, and a power supply. The turntable on the rotating shaft, when the steering wheel bounces back, the turntable will generate circumferential resistance to the steering wheel shaft under the action of the magnetic field generated by the coil of the eddy current resistance device; the resistance controller is used when the vehicle speed is lower than the set value v, the steering wheel rotation angle exceeds the set value α and After receiving the power-assisted motor failure signal sent by the vehicle controller, the coil of the eddy current resistance device is energized to provide circumferential resistance to the steering wheel shaft, which solves the problem that the current electronically controlled hydraulic power steering system of the vehicle steering system makes the steering wheel turn back when the faulty hydraulic power is interrupted. Bullets are easy to cause injury to the driver, which is a big safety hazard.
Description
technical field [0001] The invention relates to a pure electric sanitation vehicle and a vehicle steering system. Background technique [0002] The steering system is a mechanism used to maintain or change the driving direction of the car. When the car is turning, it must ensure that there is a coordinated relationship between the steering wheels. When the car is turning, all the wheels should rotate around the same instantaneous steering center. There should be sideslip. The normal steering trapezoidal linkage structure should be able to meet this requirement, but the actual vehicle cannot fully meet this requirement, and only the steering trapezoidal linkage can be optimized, generally within the common steering angle (inner wheel 15°~25°range), Make the steering relationship between inner and outer wheels close to concentric. Due to the fixed transmission ratio of the traditional automotive power steering system, it is difficult to adapt to the changes of the vehicle st...
