Abstract
A wheel suspension arm comprises a link opening (12) for pivotably securing the wheel suspension arm to a vehicle frame and an axle opening (11) for securing an axle element (2) to the wheel suspension arm. A peripheral edge (11a) of the axle opening includes at least one discontinuation, such as a slot (13). A screw (17) can be tightened to clamp the axle element (2) in the axle opening (11). The invention also relates to a method for producing the inventive wheel suspension arm and to a wheel suspension comprising said wheel suspension arm.
Claims17
A wheel suspension arm for a vehicle, the suspension arm comprising:
- a cast arm structure having a link opening for pivoting connection of the arm structure to a vehicle, and an axle opening for connecting an axle to the arm structure, wherein the axle opening defines a peripheral edge having at least one gap forming an interruption;
- and:
- a clamp configured to reduce a size of the gap and clamp the arm structure to an axle extending through the axle opening.
A method for production of a suspension assembly for a vehicle, the method comprising:
- fabricating a wheel suspension arm having an axle opening defining a peripheral edge and an interruption at the peripheral edge to permit a dimension of the axle opening to be decreased;
- providing an axle element;
- positioning at least a portion of the axle element in the axle opening;
- clamping the axle element in the axle opening.
A vehicle suspension system, comprising:
- an axle;
- a pair of suspension arms connected to the axle, each suspension arm comprising an arm structure having a link opening for connecting the suspension arm to a vehicle, the arm structure including an axle opening defining a size, and including material formed integrally with the arm structure and surrounding the axle opening and forming a discontinuity, each suspension arm including a clamp decreasing the size of the axle opening and rigidly clamping the arm structures to the axle.
