Abstract
A vehicular parking brake includes a braking device, a linear actuator, a first tie rod connected to the linear actuator, a second tie rod connected to the braking device, and a motion transmitting mechanism connecting the first tie rod to the second tie rod with a variable transmission ratio that varies based on a reaction force produced by the braking device.
Claims14
The parking brake according to claim 11, wherein the motion transmitting means is configured so that a translatory movement of the first tie rod section by the linear actuator in a first direction at a first speed up to a first level of force applied by the linear actuator causes a translatory movement of the second tie rod section in the first direction at the first speed and such that when the first level of force exceeds a first value in response to a reaction force of the braking device exceeding a second value, the transmission ratio of the motion transmitting means is changed such that the movement of the first tie rod section by the linear actuator in the first direction at the first speed causes a translatory movement of the second tie rod section in the first direction at a second speed less than the first speed.
A vehicular parking brake comprising:
- a braking device,
- a linear actuator,
- a first tie rod connected to the linear actuator,
- a second tie rod connected to the braking device, and
- motion transmitting means for moving the second tie rod in response to a movement of the first tie rod with a variable transmission ratio.
A vehicular parking brake comprising:
- a braking device,
- a linear actuator,
- a fixed support,
- a frame slidably mounted on the fixed support for linear movement relative to the frame in a first direction and in a second direction opposite the first direction,
- a first skid slidably mounted to a first linear guide on the frame,
- a second skid slidably mounted to a second linear guide on the frame,
- a first tie rod connecting the linear actuator to the first skid,
- a second tie rod connecting the second skid to the braking device,
- means for selectively blocking movement of the frame relative to the fixed support,
- a triangular body having a first vertex pivotably mounted to the frame, a second vertex and a third vertex,
- a first connecting rod extending from the first skid to the second vertex, and
- a second connecting rod extending from third vertex to the second skid.
