Abstract
A mechanical anti-lock braking apparatus for intermittently releasing pressure applied by a brake shoe to a wheel being braked includes a control member, a power input for causing the control member to rotate with the wheel around a rotational axis, and a control input for changing the position of the control member relative to a follower connected to the calipers or brackets to which the brake shoe is mounted. The control member and/or the follower has a shape which causes the follower to oscillate as the control member rotates, with the relative position of the control member and follower determining the magnitude of the oscillations.

A mechanical anti-lock braking apparatus for intermittently releasing pressure applied by a brake shoe to a wheel being braked, including:
- a control member;
- a power input for causing the control member to rotate with the wheel around a rotational axis;
- and
- a control input for changing a position of the control member relative to a follower connected to brake shoe mounting members,
- wherein the control member and follower have shapes which cause the follower to oscillate as the control member rotates, with the relative position of the control member and follower determining the magnitude of the oscillations.
Mechanical anti-lock braking apparatus for intermittently releasing pressure applied by a brake shoe to a wheel being braked, comprising:
- a control member;
- a mechanical power input for causing the control member to rotate with the wheel around a rotational axis;
- a control input for moving the control member axially along the rotational axis;
- and
- a cam follower having one end connected to the brake shoe and another end which engages and follows a camming surface of the control member,
- wherein the control member has a shape which causes the cam follower to oscillate as the control member rotates, the amplitude of the oscillations varying as the control member is axially moved along the rotational axis.
Mechanical anti-lock braking apparatus for intermittently releasing pressure applied by a brake shoe to a wheel being braked, comprising:
- means for inputting a wheel speed;
- means for inputting a magnitude of braking pressure applied by an operator of the vehicle;
- means for causing the brake shoe to oscillate in response to said wheel speed inputting means and said magnitude inputting means at a frequency which is dependent on the rotation of the wheel and at an amplitude which is dependent on the applied braking pressure,
- wherein the respective inputting means and the oscillation causing means include no electrical components.
