Abstract
A vehicle suspension assembly having a compact design and low center of gravity application. The suspension assembly includes a first link arm including a plurality of spaced pivot interfaces. A second link arm is coupled to a second pivot interface of the first link arm spaced from a first pivot interface adapted to coupled to a swing arm assembly. A shock absorber is coupled to the first link arm at a third pivot interface which is spaced from the first and second pivot interfaces with the second pivot interface positioned between the first and third pivot interfaces and the second link arm and shock absorber are coupled to a vehicle frame in stacked relation to provide a suspension assembly with a low center of gravity and small moment of inertia for moving linkages.
Claims17
A suspension assembly comprising:
- a first link arm having a first pivot interface;
- a second link arm coupled to the first link arm at a second pivot interface spaced from the first pivot interface;
- and
- a shock absorber coupled to the first link arm at a third pivot interface spaced from the first and second pivot interfaces with the second pivot interface being positioned between the first and third pivot interfaces and the shock absorber and second link arm being interfaced to the first link arm at the third and second pivot interfaces and being in stacked alignment so that the shock absorber supplies a reactive force having a perpendicular force component relative to the first link arm and not the second link arm to rotate the first link arm about the second pivot interface.
In combination:
- a vehicle chassis;
- a first link arm having a first pivot interface;
- a second link arm having a first end coupled to the first link arm at a second pivot interface spaced from the first pivot interface and a second end coupled to a vehicle chassis;
- and
- a shock absorber having a first end coupled to the first link arm at a third pivot interface spaced from the first and second pivot interfaces with the second pivot interface being positioned between the first and third pivot interfaces and a second end coupled to the vehicle chassis and the second link arm and shock absorber being in stacked alignment so that shock absorber is aligned with the first link arm to supply a reactive force at the third pivot interface to pivot the first link arm about the second pivot interface to counteract rotation of the first link arm about the first pivot interface and stacked relative to the second link arm so that a reactive force supplied does not impart a counter-rotation to the second link arm at the second end of the second link arm coupled to the vehicle chassis.
A vehicle comprising:
- a swing arm having a first end pivotally connected to a vehicle chassis and a second end coupled to a wheel and an elongated extent therebetween;
- a suspension assembly including first and second link arms and a shock absorber and the first link arm is coupled to the swing arm at a first pivot interface and the second link arm is coupled to the first link arm at a second pivot interface and the shock absorber is coupled to the first link arm at a third pivot interface spaced from the first and second pivot interfaces and the second pivot interface is between the first and third pivot interfaces with the second link arm and shock absorber coupled the vehicle chassis below an elongated axis of the swing arm.
