Vehicle steer-by-wire mode switching limit device

Abstract

The invention discloses a vehicle steer-by-wire mode switching limit device and aims at achieving steer mode switching and accurate limit of a steering wheel at any positions. A linear guide rail is fixedly arranged on a box body, a sliding block is connected onto the linear guide rail in a sliding mode, an incomplete rack and the sliding block are respectively and fixedly connected with two sides of a stroke baffle, a long groove is arranged on the lower side of the stroke baffle, a short groove is arranged in the long groove, and an incomplete gear is fixedly connected onto a driving gear shaft and is meshed with the incomplete rack. A stop block support is fixedly connected onto a bottom plate of the box body, a limit stop block is arranged in a sliding channel arranged at the upper end of the stop block support in a matching mode, a spring is arranged in the sliding channel of the stop block support, a driven frame is fixedly connected with the lower end of the limit stop block, a motor is fixedly connected onto the stop block support, a cam is fixedly connected onto an output shaft of the motor, and the outline of the cam is contacted with the inner surface of the bottom of the driven frame in a movable matching mode. The vehicle steer-by-wire mode switching limit device can achieve steering mode switching and accurate limit when the steering wheel is at any positions.

Description

technical field [0001] The invention relates to a limiting device, in particular to a limiting device for switching a steering-by-wire mode of a vehicle. 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. [0003] With the improvement of application conditions and the development of modern technology, the performance of all aspects of the vehicle needs to be further improved, especially in the steering system, the technical requirements of stable and re...

AI Technical Summary

Problems solved by technology

Due to the large rotation angle of the steering wheel, the size of the rack and the required working space will be large. However, the space of the cab floor is limited, and it is not easy to design and install.

In the existing technical solutions, the steering wheel must be returned to the initial position when the vehicle can drive straight in order to realize the switch from one steering mode to another, which lacks practicability
