Vehicle steer-by-wire steering wheel device

Abstract

The invention discloses a vehicle steer-by-wire steering wheel device, aiming at accurately detecting the rotating angle of a steering wheel, and providing adjustable and proper road feel and rotating number of turns which can change the working mode under different working conditions and adjusts the steering wheel to complete all wheel steering for a driver. A motor is fixedly connected with a box; the output shaft of the motor is fixedly connected with the lower end of a third gear shaft through a coupler; gears of the third gear shaft are in mesh transmission and matched mounting with gears of a second gear shaft; gears of the third gear shaft are in mesh transmission and matched connection with gears of a first gear shaft; gears are in mesh transmission and matched mounting with gears of a fourth gear shaft; an angle displacement sensor is fixedly connected with the upper end of a first transmission shaft; a transmission nut is in transmission and matched mounting with the thread part of the first transmission shaft; the shell of an electromagnet is fixedly connected with the box; and protecting plates at the two sides of a check block supporting seat are in movable fit and mounting with the two outer side walls of a travel check baffle. The vehicle steer-by-wire steering wheel device is suitable for being used as a steer-by-wire steering wheel of a vehicle.

Description

technical field [0001] The invention relates to a vehicle steering device, in particular to a 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] With the improvement of application conditions, the performance of vehicle steering system needs to be further improved. In order to solve the problems existin...

AI Technical Summary

Problems solved by technology

First of all, since the selected steering gear is fixed, the number of rotations required for the steering wheel from one limit position to another limit position during steering is also fixed. When performing loading operations, frequent large-angle steering is required to complete the work. At this time, the labor intensity of the operator is very high; secondly, the driver does not have a suitable road feeling during driving; thirdly, since the full hydraulic steering gear needs to be installed at the lower end of the steering wheel, the pipeline must be led near the cab, Increased assembly complexity and noise in the cab
