Abstract
The present invention is particularly useful for lowering the front end of an automobile. The devices, methods, and systems of the present invention can find use in any variety of automobiles, such as trucks, sport utility vehicles (SUVs), passenger cars, and the like. The invention can be employed regardless of the type of suspension system in the automobile, and allows the vehicle to be lowered while retaining a maximum amount of travel. This is accomplished with a drop spindle having certain features such as a tap opening and a countersunk opening on the underside of the lower ball joint boss.
Claims26
A steering knuckle for lowering the chassis frame of an automobile, the steering knuckle comprising:
- an upper ball joint boss;
- a lower ball joint boss;
- a central aperture that receives a live wheel hub assembly;
- and
- a tap opening comprising a threaded section oriented for receiving a threaded hub assembly stud or bolt;
- wherein the threaded section of the tap opening is adapted to receive the threaded hub assembly stud or bolt alone a central longitudinal axis defined by the tap opening such that the threaded hub assembly stud or bolt engages the threaded section of the tap opening with a central longitudinal axis defined by the threaded hub assembly stud or bolt collinear with the central longitudinal axis defined by the tap opening and wherein the central longitudinal axis defined by the tap opening intersects with the upper ball joint boss.
A method of lowering the chassis frame of an automobile, the method comprising coupling an upper A-frame and a lower A-frame of the automobile with a steering knuckle that includes:
- an upper ball joint boss;
- a lower ball joint boss;
- a central aperture that receives a live wheel hub assembly;
- and
- a tap opening comprising a threaded section oriented for receiving a threaded hub assembly stud or bolt;
- wherein the threaded section of the tap opening is adapted to receive the threaded hub assembly stud or bolt along a central longitudinal axis defined by the tap opening such that the threaded hub assembly stud or bolt engages the threaded section of the tap opening with a central longitudinal axis defined by the threaded hub assembly stud or bolt collinear with the central longitudinal axis defined by the tap opening, and wherein the central longitudinal axis defined by the tap opening intersects with the upper ball joint boss.
A system that lowers the front end of an automobile, wherein the system includes:
- a steering knuckle comprising:
- an upper ball joint boss coupled with an upper control arm of the automobile;
- a lower ball joint boss coupled with a lower control arm of the automobile via a lower ball joint housing;
- a central aperture that receives a live wheel hub assembly;
- and
- a tap opening comprising a threaded section oriented for receiving a threaded hub assembly stud or bolt;
- and
- a spacer at least partially disposed inside a lower A-frame;
- wherein the threaded section of the tap opening is adapted to receive the threaded hub assembly stud or bolt along a central longitudinal axis defined by the tap opening such that the threaded hub assembly stud or bolt engages the threaded section of the tap opening with a central longitudinal axis defined by the threaded hub assembly stud or bolt collinear with the central longitudinal axis defined by the tap opening, and wherein the central longitudinal axis defined by the tap opening intersects with the upper ball joint boss.
A steering knuckle for lowering the chassis frame of an automobile, the steering knuckle comprising:
- a steering knuckle body;
- an upper ball joint boss extending from the steering knuckle body;
- a lower ball joint boss extending from the steering knuckle body;
- an aperture in the steering knuckle body, the aperture disposed between the upper ball joint boss and the lower ball joint boss and adapted for receiving a wheel hub assembly;
- and
- a tap opening comprising a threaded section adapted for receiving a threaded hub assembly stud or bolt along a central longitudinal axis defined by the tap opening, the threaded hub assembly stud or bolt coupling the steering knuckle to the wheel hub assembly;
- wherein the threaded section of the tap opening is adapted to receive the threaded hub assembly stud or bolt such that the threaded hub assembly stud or bolt engages the threaded section of the tap opening with a central longitudinal axis defined by the threaded hub assembly stud or bolt collinear with the central longitudinal axis defined by the tap opening, and wherein the central longitudinal axis defined by the tap opening intersects with the upper ball joint boss.
