Abstract

The invention discloses a bevel-gear-type vehicle drive-by-wire steering wheel device in order to achieve the purposes that the rotation angle of a steering wheel can be detected accurately, adjustable and appropriate road feels can be provided for drivers, the working mode can be changed on different working conditions and full-wheel-steering rotation turns are completed by adjusting the steering wheel. A gear shaft is installed in a bearing seat of a box through a bearing, an electromagnetic coil is fixedly installed on the box, and a damping disk is fixedly connected to the lower end of the gear shaft. A driven bevel gear is fixedly installed at the right end of a transmission lead screw, a driving bevel gear is fixedly installed on the gear shaft, and the driven bevel gear and the driving bevel gear are installed in a meshed, transmission and matched mode. A transmission lead screw is installed on the box through a bearing, and a transmission nut and the transmission lead screw are installed in a transmission and matched mode. A shell of an angular displacement sensor is fixedly installed on the box, and an input hollow shaft of the angular displacement sensor is fixedly connected with the transmission lead screw. The bevel-gear-type vehicle drive-by-wire steering wheel device is suitable for being used as a drive-by-wire steering wheel of a vehicle.

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...
