Macpherson suspension system

Abstract

The invention provides a Macpherson suspension system. The system comprises a shock absorber (1), a knuckle (2), a connecting piece (3) for connecting the shock absorber (1) and the knuckle (2), a bolt (4) arranged on the connecting piece (3), a groove bolt (5) and eccentric washers (7), wherein grooves (6) are formed at the thread positions of the groove bolt (5); a positioning device is arranged at the contact position of the groove bolt (5) and the connecting piece (3); and the eccentric washers (7) are arranged between the groove bolt (5) and connecting holes (8) of the connecting piece (3) and provided with bulges (9) protruded on the inner walls of the eccentric washers (7). The traditional Macpherson suspension system in which a kingpin inclination angle cannot be adjusted is improved into the Macpherson suspension system in which the kingpin inclination angle can be adjusted and changed, so that the application range and maintenance range of the Macpherson suspension system are expanded, and a larger free design space is provided for an automobile.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, and more specifically relates to a McPherson suspension system. Background technique [0002] McPherson suspension is a suspension form invented by McPherson, a famous chassis engineer of General Motors in the United States. Due to the phenomenon of offset, the spring can only vibrate in the up and down direction, and the stroke length and tightness of the shock absorber can be used to set the hardness and performance of the suspension. [0003] With the development of automobile product technology, people have higher and higher requirements on the performance and function of automobiles. However, due to the limitation of design structure, the four-wheel alignment parameters of McPherson suspension system except the toe value (from the top of the car to the Looking down, the left and right wheels form a "eight" shape with an opening facing backward.

Problems solved by technology

[0003] With the development of automobile product technology, people have higher and higher requirements on the performance and function of automobiles. However, due to the limitation of design structure, the four-wheel alignment parameters of McPherson suspension system except the toe-in value (from the top of the car to the Looking down, the left and right wheels form a "eight" shape with an opening facing backward. The distance between the front end of the two wheels of the car is smaller than the distance between the rear end, that is, the distance between the upper opening of the "eight" character is smaller than the distance between the lower end opening, and the difference between the distances is called front. Beam value), the other three values ​​are guaranteed by design and cannot be adjusted. In this design method, the value of the kingpin inclination angle of the automobile wheel is fixed and cannot be changed. The maintenance performance is not very high, and Because the inclination angle of the kingpin cannot be adjusted, it will also cause a certain degree of wheel wear and vehicle deviation, which makes its design and manufacturing process have certain defects.
