Abstract
A self-energizing brake caliper comprises a caliper bracket fixed to a vehicle frame, a first caliper arm rotatably connected to the caliper bracket, a second caliper arm rotatably connected to the caliper bracket, an inboard brake pad, and an outboard brake pad. The first caliper arm is rotatably connected to the outboard brake pad at a first position and is configured to press against the outboard brake pad at the first position by receiving the power of an actuator at the second position which is inboard side. The second caliper arm is rotatably connected to the inboard brake pad at a third position and is configured to press against the inboard brake pad at the third position by receiving the power of an actuator at the fourth position which is inboard side.
Claims20
A self-energizing brake caliper comprising:
- a caliper bracket fixed to a vehicle frame;
- a first caliper arm rotatably connected to the caliper bracket with a rotational axis parallel to a radial direction with respect to a brake disc;
- a second caliper arm rotatably connected to the caliper bracket with a rotational axis parallel to the radial direction with respect to the brake disc;
- an inboard brake pad;
- and
- an outboard brake pad;
- wherein the first caliper arm is rotatably connected to the outboard brake pad at a first position and is configured to press against the outboard brake pad at the first position by receiving the power of an actuator at a second position which is at inboard side;
- and extends from the first position to the second position via a position at which the first caliper arm is connected to the caliper bracket,
- wherein the second caliper arm is rotatably connected to the inboard brake pad at a third position and is configured to press against the inboard brake pad at the third position by receiving the power of an actuator at a fourth position which is at the inboard side, and extends from the fourth position to a position at which the second caliper arm is connected to the caliper bracket via the third position, and
- wherein a friction force generated by the outboard brake pad during braking creates a moment for the first caliper arm to exert an axial force on the outboard brake pad toward the inboard side, and a friction force generated by the inboard brake pad during the braking creates a moment for the second caliper arm to exert an axial force on the inboard brake pad toward the outboard side.
A self-energizing brake caliper comprising:
- a caliper bracket fixed to a vehicle frame;
- a first caliper arm rotatably connected to the caliper bracket;
- a second caliper arm rotatably connected to the caliper bracket;
- an inboard brake pad;
- and
- an outboard brake pad;
- wherein the first caliper arm receives the power of an actuator at 1-1 position, is rotatably connected to the caliper bracket at 2-1 position, is rotatably connected to the outboard brake pad at 3-1 position which is between the 1-1 position and the 2-1 position, and is configured to press against the outboard brake pad at the 3-1 position by the power of the actuator;
- and
- wherein the second caliper arm receives the power of an actuator at 4-1 position, is rotatably connected to the caliper bracket at 2-1 position, is rotatably connected to the inboard brake pad at an intermediate position which is between the 4-1 position and the 2-1 position, and is configured to press against the inboard brake pad at the intermediate position by the power of the actuator.
