Problems solved by technology

During the up-and-down jumping process of the suspension of the existing structure, the change curve of the toe-in and camber angle is fixed, that is, the initial reference change curve at the factory, and the matching relationship between the toe-in and camber is also unique, resulting in different road conditions and loads. At different times, the handling and driving comfort embodied by the same suspension are also different, and the degree of wear of the tires will also be different.

Embodiment Construction

[0030] For ease of description, some nouns or terms involved in the embodiments of the present application are described below:

[0031] Camber: Viewed from the front of the car, the top of the car wheel is inclined inward or outward at an angle, which is called the camber of the wheel. Normally, the roll angle of a car is camber. It is expressed by the angle of inclination from the vertical line. If the top slopes outward, it is called positive camber, and if it slopes inward, it is called negative camber. The function of camber is to increase the safety of straight-line driving of the car. When there is a camber angle, the offset of the wheel can be reduced when turning, so it can reduce the steering force; in addition, due to the camber of the wheel, under the action of vertical load Generate a component force applied to the shaft, so that the wheel is pressed inwardly on the bearing to prevent the wheel from being thrown off.

[0032] Toe-in: Looking down from the top of...

Abstract

The invention discloses a wheel toe-in camber full-dynamic control device and method for a multi-link suspension. The dynamic control device comprises an acquisition module, a controller, a toe-in adjustment execution device and a camber adjustment execution device, various real-time motion parameters of a vehicle are collected through the acquisition module, the current motion working condition of the vehicle is judged, and then the real-time toe-in control arm adjustment amount and the camber control arm adjustment amount of the vehicle are calculated, and the toe-in control arm and the camber control arm are adjusted to achieve the optimal ideal toe-in camber angle so that the wheel has proper toe-in angle and camber angle under various motion working conditions facing different road conditions, the safety of the wheel is improved, the tire wear is effectively reduced, and the service life of the tire is prolonged. According to the dynamic control method, the wheels have proper camber angles under various motion working conditions, and the toe-in angles corresponding to the camber angles are matched in real time.

Description

technical field [0001] The invention relates to the field of automobile wheel control, in particular to a full-dynamic control device and method for wheel toe camber of a multi-link suspension. Background technique [0002] The toe-in and camber curves of the vehicle suspension depend on the definition of the initial angle and the arrangement of the hard points of the suspension. level of driving comfort. During the up-and-down jumping process of the suspension of the existing structure, the change curve of the toe-in and camber angle is fixed, that is, the initial reference change curve at the factory, and the matching relationship between the toe-in and camber is also unique, resulting in different road conditions and loads. At different times, the handling and driving comfort embodied by the same suspension are also different, and the degree of wear of the tires will also be different. Contents of the invention [0003] The purpose of the present invention is to overc...
