Mounting assembly for a vehicle suspension arm
First Claim
1. A mounting assembly for a rotating arm comprising:
- an arm with a longitudinal axis and a cylindrical bore at one end of said arm, said cylindrical bore having a bore axis transverse to said longitudinal axis, a pin extending through said bore, a pair of clamping blocks, each of said clamping blocks having a central opening, each of said clamping blocks being circumferentially discontinuous about its central opening, when unclamped, and each of said clamping blocks having a slot defined by portions thereof, said central openings being dimensioned to allow said pin to pass through said openings in a first unclamped position and tightly gripping said pin in a second clamped position;
said pin having a pair of opposing fasteners, one at each end of said pin.

Abstract
A mounting assembly for a rotating arm, such as a control arm of an independent suspension. The mounting assembly includes a pin which passes through a cylindrical bore in one end of the arm. The pin is gripped at each end by a clamping block. Each block has a main pin-gripping opening for one end of the pin, and the opening has an initial size which allows the end of the pin to pass easily through the opening. However, when the clamping block is tightened, such as by mounting the block to a support, the opening is made smaller so as to grip the end of the pin. The arrangement allows easy removal of the pin and therefore easy replacement of the control arm of a vehicle suspension.
