Abstract
The present disclosure further relates to a positioning assembly, such as for positioning a brake piston. The positioning assembly comprises a support member extending along an axis, a first compression-loaded member, and a second compression-loaded member, wherein the first compression-loaded member and the second compression-loaded member are axially supported on or configured to be axially supported on the support member. The present disclosure further relates to a brake piston assembly including said positioning assembly.
Claims16
A positioning assembly for positioning a brake piston, the positioning assembly comprising:
- a support member extending along an axis, a first compression-loaded member, and a second compression-loaded member, wherein the first compression-loaded member and the second compression-loaded member are axially supported on or configured to be axially supported on the support member;
- wherein the second compression-loaded member includes a conical portion that tapers along an axial length of the second compression-loaded member;
- wherein the second compression-loaded member includes one or more notches that at least partially extend along the conical portion;
- and
- wherein the first compression-loaded member at least partially circumferentially surrounds at least a portion of the second compression-loaded member.
A brake piston assembly, comprising:
- a stationary portion,
- a brake piston, and
- a positioning assembly, comprising:
- a support member extending along an axis,
- a first compression-loaded member, and
- a second compression-loaded member,
- wherein the first compression-loaded member and the second compression-loaded member are axially supported on or configured to be axially supported on the support member;
- wherein the support member is rigidly connected to the stationary portion;
- wherein the brake piston is movable relative to the stationary portion along a piston axis arranged in parallel to the axis of the support member;
- wherein the second compression-loaded member is in frictional engagement with a portion of the brake piston;
- and
- wherein the second compression-loaded member and the brake piston are configured such that axial movement of the brake piston relative to the second compression-loaded member toward the stationary portion increases frictional engagement between the second compression-loaded member and the brake piston, and axial movement of the brake piston relative to the second compression-loaded member away from the stationary portion decreases frictional engagement between the second compression-loaded member and the brake piston.
