Keyed contour braking system for a commercial vehicle
View Patent ↗Various embodiments of the invention relate to a vehicle, especially a commercial vehicle, with a braking system for a wheel of the vehicle having an axle arrangement and a brake, especially a disc brake, whereby the cross-section of the axle arrangement has an outer contour differing from a circle, and the brake has a brake carrier. According to one embodiment of the invention, the brake carrier has an opening whose inner contour differs from a circle and the outer contour lies on the axle arrangement such that the brake carrier surrounds the axle of the brake to form a keyed fit with the axle arrangement.
1. A braking system, comprising:
an axle arrangement having a cross-section with an outer contour that differs from a circle; and
a brake, coupled to the axle arrangement, having a brake carrier with an opening having a non-circular inner contour on the outer contour of the axle arrangement such that the brake carrier surrounds the axle of the brake to form a keyed fit with the axle arrangement, wherein
the brake carrier is plate-shaped, and a brake pad is held and guided by a contact surface on the brake carrier.
2. The braking system according to claim 1 , wherein the inner contour of the opening provides a closed structure around the axle arrangement.
3. The braking system according to claim 1 , wherein the inner contour of the opening encloses the axle arrangement at an angle less than 360°.
4. The braking system according to claim 3 , wherein the inner contour of the opening is shaped like a “C” or “U”.
5. The braking system according to claim 4 , wherein the two legs of the “C” or “U” enclose a sharp angle of preferably about 0.2° to about 5°.
6. The braking system according to claim 1 , wherein the inner contour of the opening fits in two or more angled positions around the axle of the brake on the outer contour of the axle arrangement.
7. The braking system according to claim 1 , wherein at least one contact surface on the axle arrangement acting in the direction of the axle of the brake is configured to axially fix the brake carrier on the axle arrangement.
8. The braking system according to claim 1 , further comprising at least one screw lying perpendicular to the axle of the brake to fasten the brake carrier on the axle arrangement.
9. The braking system according to claim 8 , wherein a first screw and at least one other screw, perpendicular to the axle of the brake, are offset from each other in the direction of the axle.
10. The braking system according to claim 1 , wherein the brake carrier is welded to the axle arrangement.
11. The braking system according to claim 1 , wherein the outer contour of the axle arrangement is a shape selected from the group consisting of a square, a rectangle, a triangle, a parallelogram, a trapezoid, and an oval.
12. The braking system according to claim 1 , wherein the inner contour of the opening is a shape selected from the group consisting of a square, a rectangle, a triangle, a parallelogram, a trapezoid, and an oval.
13. The braking system according to claim 1 , wherein the inner contour of the opening includes at least two rotatably offset squares.
14. The braking system according to claim 1 , wherein no part of the brake carrier projects beyond the outer perimeter of a brake disc of the brake.
15. The braking system according to claim 1 , wherein the brake carrier is configured to hold and to guide a braking-side brake pad of the brake and/or a pressure plate of the brake.
16. The braking system according to claim 1 , further comprising a clamping device to clamp the free ends of the inner contour of the opening to the outer contour of the axle arrangement.
17. The braking system according to claim 16 , further comprising a braking-side brake pad symmetrical with the clamping device and a rim-side brake pad offset perpendicular to the axle of the brake in the direction of a disk exit side in the preferred direction of rotation.
18. The braking system according to claim 1 , further comprising a guide pin affixed to the brake carrier and movably mounted to a sliding caliper of the brake.
19. A vehicle, comprising:
at least one wheel; and
a braking system, coupled to the at least one wheel, having an axle arrangement and a brake, the axle arrangement having a non-circular outer contour cross-section and the brake having a brake carrier, defining a non-circular inner contour opening, and lying on the outer contour of the axle arrangement such that the brake carrier surrounds the axle of the brake to form a keyed fit with the axle arrangement, wherein
the brake carrier is plate-shaped, and a brake pad is held and guided by a contact surface on the brake carrier.
