Abstract

The invention discloses a cam type vehicle steer-by-wire steering wheel device, aiming at accurately detecting the rotation angle of a steering wheel, providing adjustable and appropriate road sense for a driver, and changing a work mode under different work conditions and adjusting the steering wheel to complete the turning number of full steering. A center shaft is mounted on an upper end cover and a box body by bearings; an electromagnetic coil is fixedly mounted in an electromagnetic coil box; the electromagnetic coil box is fixedly connected with the upper end cover; a damping disc is fixedly connected with the center shaft; a limit nut and a thread part of the center shaft are mounted in a transmission fit mode; a baffle ring is mounted on the center shaft in a sleeving way; a driven frame and front and rear groove baffles are mounted in a sliding fit mode; a camshaft and an output shaft of a direct current motor are fixedly connected; a cam and the camshaft are mounted in a matching way by pretightening mechanisms; a first proximity switch is fixedly mounted on the box body; a second proximity switch is fixedly mounted on the rear groove baffle. The cam type vehicle steer-by-wire steering wheel device is applicable to a vehicle and can be used as a steer-by-wire steering wheel.

Description

technical field [0001] The invention relates to a vehicle steering device, in particular to a cam 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 patent application number is 201310322163.7, which is a patent for a vehicle steering wheel steering wheel device, which can change the working mo...
