Abstract
A suspension for a vehicle provides a configuration in which a bolt is screw-fastened to a stud part of a ball joint in a state in which the stud part is inserted into a knuckle, an outer diameter of the stud part is increased at the time of fastening the bolt so that the stud part and the knuckle are coupled to each other. Thus, a position of a hard point corresponding to a center of the ball joint is not changed when the ball joint is coupled by the bolt.
Claims11
A suspension for a vehicle, the suspension comprising:
- a lower arm and a knuckle disposed to be spaced apart from each other;
- a ball joint including:
- a first end having a ball part and coupled to the lower arm, and a second end corresponding to a stud part and installed by being inserted into the knuckle;
- and
- a bolt fastened to the stud part by penetrating the knuckle in a direction opposite to a direction in which the stud part is inserted, the bolt configured to enter the stud part in a longitudinal direction of the stud part,
- wherein the stud part is spread outward and expanded in outer diameter when the bolt is fastened to the stud part, and
- wherein a restrictive force is implemented as a contact between the stud part and the knuckle increases when the outer diameter is expanded, such that the stud part and the knuckle are coupled.

- a head part insertion groove into which a head part of the bolt is inserted and seated, and
- an intermediate hole configured to connect the stud part insertion groove and the head part insertion groove,
- wherein the stud part insertion groove, the head part insertion groove, and the intermediate hole are connected to each other on a same axis,
- wherein even though an axial force is applied in an axial direction to the ball joint when the bolt is fastened to the stud part in a state in which the stud part is inserted into the stud part insertion groove, a state in which the stud part is supported in the stud part insertion groove is maintained such that the ball joint does not move in the axial direction, and
- wherein a position of a hard point of the ball joint is not changed as the ball joint does not move in the axial direction at a time of fastening the bolt.
