Abstract

The invention discloses a bevel-gear steering-by-wire steering wheel device for a vehicle, which aims at accurately detecting the rotation angle of the steering wheel, can provide the driver with an adjustable and suitable road feeling, and can change the working mode under different working conditions. Adjust the number of turns of the steering wheel to complete a full turn. The gear shaft is installed in the bearing seat of the box body through bearings, the electromagnetic coil is fixedly installed on the box body, and the damping disc is fixedly connected to the lower end of the gear shaft. The driven bevel gear is fixedly mounted on the right end of the transmission lead screw, the driving bevel gear is fixedly mounted on the gear shaft, and the driven bevel gear and the driving bevel gear are meshed and transmitted for installation. The transmission screw is installed on the box body through the bearing, and the transmission nut is installed in cooperation with the transmission of the transmission screw. The housing of the angular displacement sensor is fixedly installed on the box body, and the input hollow shaft of the angular displacement sensor is fixedly connected with the transmission lead screw. The invention is applicable to vehicles as a steer-by-wire steering wheel.

Description

technical field [0001] The invention relates to a vehicle steering device, in particular to a bevel gear type vehicle steering-by-wire steering wheel device. Background technique [0002] The function of the steering system is to control the driving direction of the vehicle. The system should be able to keep the vehicle running in a straight line stably and flexibly change the driving direction according to the requirements. The basic requirements for the steering system are light and flexible operation, stable and reliable operation, and economical and durable use. The steering performance is an important factor to ensure the safe driving of the vehicle, reduce the labor intensity of the driver, and improve the work productivity. The steering system is a key assembly that determines vehicle safety and operating efficiency. [0003] The vehicle steer-by-wire steering wheel device with the patent application number 201310025567.X can change the working mode under different w...
