Abstract

An electrical-mechanical brake apparatus includes a bracket and a pedal arm supported by the bracket. The bracket has a cam surface. An arm extends from the pivot arm to a follower. As the pedal arm moves toward the bracket, the follower moves along the cam surface, compressing the cam bias for simulating the feel of a purely mechanical brake system. In certain embodiments, the earn body rotates while in others the cam follower rotates.

Claims

1. A pedal assembly for a pedal arm of a vehicle comprising:

a bracket for pivotally supporting the pedal arm about a pivot axis, the bracket having a cam surface positioned radially outward from the pivot axis;

an arm extending from the pedal arm to the cam surface;

a follower mounted to an end of the arm;

a biasing spring forcing the follower member against the cam surface such that hysteresis is generated when the pedal arm is depressed.

2. The pedal assembly of claim 1, wherein the pedal assembly further comprises a main spring extending between the pedal arm and the bracket.

3. The pedal assembly of claim 1, further comprising a hub mounted to the pedal arm about the pivot axis and wherein the arm extends from the hub.

4. The pedal assembly of claim 3, wherein the follower is a roller.

5. The pedal assembly of claim 4, further comprising a hysteresis spring extending between the roller and the hub.

6. The pedal assembly of claim 5, wherein the arm is a telescoping arm.

7. The pedal assembly of claim 1, wherein the follower is a shoe.

8. The pedal assembly of claim 7, further comprising a biasing arm extending between one end of the arm and the shoe.

9. The pedal assembly of claim 8, wherein the biasing spring extends between the bracket and the biasing arm.
