Problems solved by technology

The setting of the McPherson front suspension system causes periodic vibration in the front and rear direction due to the dynamic imbalance of the tire when the wheel rotates. Vibration is transmitted to the driver; especially when driving on the highway, this movement can occur at a certain speed even if the roa

Embodiment Construction

[0031] Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the following description is only illustrative and exemplary.

[0032] figure 2 is a schematic diagram of a MacPherson suspension control arm according to one embodiment of the invention. As shown in the figure, the control arm 1 of the front MacPherson suspension of an automobile includes a control arm body 10 , a ball stud 11 , a front frame bushing 12 and a rear frame bushing 13 . A ball stud 11 is located on the control arm body 10 and is used to connect the steering knuckle. Front frame bushings 12 and rear frame bushings 13 are also located on the control arm body 10 and are used to attach to a frame (not shown). Considering that those skilled in the art already have a good understanding of the conventional settings of the MacPherson suspension, the connection relationship between the MacPherson suspension re...

Abstract

The invention relates to an automotive front Macpherson suspension and an automobile comprising the same. A control arm of the automotive front Macpherson suspension comprises a control arm body, a ball pin, a front frame bushing and a rear frame bushing, wherein the ball pin is positioned on the control arm body and is connected with a steering joint; the front frame bushing and the rear frame bushing are positioned on the control arm body and are connected with a frame; at least one of the front frame bushing and the rear frame bushing is made of a rubber material, and the radial rigidity is greater than the axial rigidity. Moreover, the invention also provides an arrangement relationship between key hard points of the control arm. According to the automotive front Macpherson suspension and the corresponding automobile, the rigidity characteristic of front and rear automobile reinforcing bushings on the control arm is perfectly designed, the relationship between the key hard points of the control arm is advantageously designed, the dynamic unbalance of a tire assembly when a vehicle runs at high speed and the vibration transferred to a driver by the frame are reduced, and the driving control and the driving comfort are improved.

Description

technical field [0001] The invention relates to an automobile chassis suspension system; more specifically, the invention relates to an automobile front MacPherson suspension. Furthermore, the present invention also relates to an automobile comprising such a front MacPherson suspension. Background technique [0002] As we all know, the driving control and comfort of a car are closely related to the suspension system in the chassis structure. At the same time, the simplicity and complexity of the suspension system structure also directly determines the level of car manufacturing costs. [0003] At present, the front suspension of most cars adopts McPherson independent suspension, such as figure 1 As shown in , this suspension system is mainly composed of a control arm 1, a spring damper assembly 2, a steering knuckle 3, and a stabilizer bar (not shown). figure 1 The part shown by the middle dotted line represents the front wheel corresponding to the suspension. McPherson ...
