Abstract

A low suspension arm strut coupling is provided for a suspension of an off-road vehicle. The suspension comprises a lower suspension arm that is hingedly coupled between a chassis of the off-road vehicle and a spindle assembly that is coupled with a front wheel. An upper suspension arm is hingedly coupled between the chassis and the spindle assembly. A strut is coupled between the lower suspension arm and the chassis. A lower pivot couples the strut to the lower suspension, and an upper pivot couples the strut to the chassis. The upper and lower pivots provide a lower center of gravity of the off-road vehicle and a relatively smaller shock angle. The lower suspension arm is reinforced to withstand forces due to movement of the front wheel and operation of the strut in response to travel over terrain.

First claim

What is claimed is:

1. A front suspension for coupling a front wheel with a chassis of an off-road vehicle, comprising:
a spindle assembly for mounting the front wheel;
an upper suspension arm for coupling an upper portion of the spindle assembly to the chassis wherein the upper suspension arm is configured to accommodate the strut being disposed between the lower suspension arm and the chassis wherein the upper suspension arm includes one or more inboard mounting points that are configured to be coupled with locations of the chassis forward of inboard mounting points comprising the lower suspension arm;
a lower suspension arm for coupling a lower portion of the spindle assembly to the chassis;
a lower pivot comprising the lower suspension arm for receiving a strut to dampen vertical motion of the lower suspension arm, wherein the lower pivot is configured to cooperate with an upper pivot to couple the strut between the lower suspension arm and the chassis; and
a leading portion of the spindle assembly for steering the front wheel.

2. A front suspension for coupling a front wheel with a chassis of an off-road vehicle, comprising:
a spindle assembly for mounting the front wheel;
an upper suspension arm for coupling an upper portion of the spindle assembly to the chassis;
a lower suspension arm for coupling a lower portion of the spindle assembly to the chassis;
a lower pivot comprising the lower suspension arm for receiving a strut to dampen vertical motion of the lower suspension arm the lower pivot is configured to cooperate with an upper pivot to couple the strut between the lower suspension arm and the chassis wherein the lower pivot is configured to cooperate with an upper pivot to provide a substantially 90-degree angle between the strut and the lower suspension arm during full compression of the strut; and
a leading portion of the spindle assembly for steering the front wheel.

3. A lower suspension arm for a front suspension of an off-road vehicle, comprising:
one or more inboard mounting points for coupling to a chassis of the vehicle;
an outboard mounting point for coupling with a spindle assembly;
a tube end welded to the outboard mounting point for receiving a rod-end joint coupled with the spindle assembly; and
a lower pivot for coupling to a strut wherein the lower pivot is configured to provide a substantially 90-degree angle between the strut and the lower suspension arm during full compression of the strut.
