Abstract

An apparatus for a vehicle is provided that has a spindle sleeve ( 12 ) with a spindle sleeve inner surface axis ( 14 ) that is coaxial with the axis of an axle ( 16 ). The spindle sleeve ( 12 ) has a spindle sleeve outer surface axis ( 20 ) that is oriented at an angle to the axis of the axle. A hub ( 28 ) is present that has a hub axis ( 30 ) that is coaxial with the spindle sleeve outer surface axis ( 20 ). A rotor ( 32 ) is coaxial with the hub axis ( 30 ) and brake calipers ( 34 ) are carried by the axle. A brake caliper positional correction device ( 36 ) is present and is carried by the axle ( 16 ) and has a correction surface ( 38 ) that carries the brake calipers ( 34 ). The correction surface ( 38 ) orients the brake calipers ( 34 ) such that the brake calipers ( 34 ) are properly positioned with respect to the rotor ( 32 ).

First claim

What is claimed is:

1. An apparatus for a vehicle, comprising:
a spindle sleeve with a spindle sleeve inner surface axis that is coaxial with the axis of an axle, wherein the spindle sleeve has a spindle sleeve outer surface axis that is oriented at an angle to the axis of the axle, wherein the spindle sleeve has an inner surface and an outer surface;
a hub that has a hub axis that is coaxial with the spindle sleeve outer surface axis, wherein a rotor is coaxial with the hub axis and wherein brake calipers are carried by the axle; and
a brake caliper positional correction device that is carried by the axle and has a correction surface that carries the brake calipers, wherein the correction surface orients the brake calipers such that the brake calipers are properly positioned with respect to the rotor;
wherein the axle has a caliper mounting bracket rigidly attached to a shaft of the axle, wherein the brake caliper positional correction device is attached to the caliper mounting bracket by a plurality of mounting bolts;
wherein the brake caliper positional correction device has an outboard component and an inboard component, wherein the correction surface is located on the outboard component, wherein the outboard component engages the caliper mounting bracket such that the correction surface does not engage the caliper mounting bracket, wherein the inboard component engages the caliper mounting bracket such that the caliper mounting bracket is located outboard from the inboard component and such that the caliper mounting bracket is located inboard from the outboard component.

2. The apparatus of claim 1 , wherein the angle the spindle sleeve outer surface axis is oriented with respect to the spindle sleeve inner surface axis is greater than zero degrees.

3. The apparatus of claim 1 , wherein the correction surface faces the brake calipers.

4. The apparatus of claim 3 , wherein the correction surface engages the brake calipers.

5. The apparatus of claim 1 , wherein the brake caliper positional correction device has a back surface that is oppositely disposed to the correction surface, wherein the back surface is oriented at a brake caliper positional correction device angle to the correction surface, wherein the brake caliper positional correction device angle is greater than zero.

6. The apparatus of claim 1 , wherein the brake caliper positional correction device angle is a compound angle.

7. The apparatus of claim 1 , wherein the brake caliper positional correction device positions the brake calipers in an outboard direction of the axle.

8. The apparatus of claim 1 , wherein the brake caliper positional correction device has a plurality of holes through which the plurality of mounting bolts are disposed.

9. The apparatus of claim 1 , wherein the inboard component has a caliper mounting bracket engagement surface that engages the caliper mounting bracket, wherein the inboard component has a bolt mounting surface that engages the mounting bolts, wherein the bolt mounting surface is oriented at an angle that is greater than zero to the caliper mounting bracket engagement surface,
wherein the mounting bolts extend through the inboard component, the caliper mounting bracket, the outboard component, and into the brake calipers and are in threaded engagement with the brake calipers.

10. The apparatus of claim 9 , wherein the outboard component includes an upper outboard component and a lower outboard component, wherein the upper outboard component is spaced from and free from contact with the lower outboard component, wherein the correction surface is located on both the upper outboard component and the lower outboard component, wherein the mounting bolts extend through both the upper outboard component and the lower outboard component,
wherein the inboard component includes an upper inboard component and a lower inboard component, wherein the upper inboard component is spaced from and free from contact with the lower inboard component, wherein the bolt mounting surface is located on both the upper inboard component and the lower inboard component, wherein the mounting bolts engage and extend through both the upper inboard component and the lower inboard component.

11. The apparatus of claim 10 , wherein the upper inboard component, the lower inboard component, the upper outboard component, and the lower outboard component each have a different number of identification holes that identify the upper inboard component, the lower inboard component, the upper outboard component, and the lower outboard component from one another.

12. The apparatus of claim 1 , wherein the brake calipers have a first brake pad and a second brake pad that move into engagement with the rotor to stop the rotor from spinning, wherein the first brake pad is located inboard of the rotor, wherein the second brake pad is located outboard of the rotor.

13. The apparatus of claim 12 , wherein when the brake calipers are properly positioned with respect to the rotor the first brake pad is in alignment with the rotor and the second brake pad is in alignment with the rotor, wherein when the brake calipers are properly positioned with respect to the rotor the distance from the first brake pad to the rotor is the same as the distance from the second brake pad to the rotor.
