AI Technical Summary

Problems solved by technology

[0009] The problem with the above-mentioned conventional opening angle adjustment mechanism using a hydraulic linear actuator is that the hydraulic unit, that is, the hydraulic linear actuator occupies a relatively large space and has a slow response time
In addition, such hydraulic control systems are quite complex and include a relatively large number of complex components, thereby limiting throughput

Embodiment Construction

[0025] Detailed description of the preferred embodiment

[0026] Now refer to the attached Figures 3 to 9 , the opening angle adjustment mechanism 100 using an electric linear actuator according to a preferred embodiment of the present invention will be described in detail. Like numbers in the drawings indicate like parts.

[0027] image 3 Among them, the opening angle adjustment mechanism 100 for the vehicle suspension system includes a pair of rear wheels 30, a rear cross member 31, a pair of steering knuckles 32, a pair of control arms 33, a pair of electric linear actuators 36, and a pair of linkage Rod 37. Each rear wheel 30 is rotationally coupled to a corresponding steering knuckle 32 which is pivotally coupled to a control arm 33 and a rear arm (not shown). The rear arm supports a steering knuckle 32 arranged in the longitudinal direction of the vehicle and a control arm 33 perpendicular to its longitudinal centerline. The suspension system also includes a spring...

Abstract

A toe angle adjustment mechanism includes an electrical linear actuator, an interconnection arm, and a control lever, wherein the electrical linear actuator is mounted on a rear cross member of a vehicle having a pair of rear wheels. The interconnection arm, pivotally attached to the rear cross member, pivotally interconnects the electrical linear actuator with the control lever, which is pivotally connected with a steering knuckle rotationally coupled with a corresponding rear wheel. The electrical linear actuator includes a housing, a motor, a ball screw rotated by the motor, a ball nut operatively mounted on the ball screw for linear movement therealong in response to rotation of the ball screw by the motor, and a nut rod attached to the ball nut.

Description

technical field [0001] The present invention relates to a splay angle adjustment mechanism for a vehicle, and more particularly, to an effective splay angle adjustment mechanism that uses an electric linear actuator to effectively adjust the splay angle of a rear wheel of a vehicle. Background of the invention [0002] Vehicle suspension systems are used to provide comfort to vehicle occupants and to enhance the drivability of the vehicle. To this end, the vehicle should be effectively protected from the impact of forces due to uneven road conditions, so that the driver of the vehicle can comfortably control the vehicle, have a good grip on the vehicle and obtain good feedback from the vehicle. [0003] This vehicle suspension system provides more passenger comfort and improves drivability by using an effective splay angle adjustment mechanism. The difference between the steering angle of the inner wheel and the steering angle of the outer wheel defines the opening angle. ...
