US 9,845,083 B2 · Park brake control assembly

Abstract

A parking brake control assembly having a brake actuator includes an engagement member, a retention member, a release actuator, and a biasing member. In a first position of brake actuator, the retention member is arranged to engage the engagement member upon movement of the brake actuator from a first position to a second position to hold the brake actuator in the second position. Movement of the brake actuator from the first to the second position causes the release actuator to move relative to the retention member such that the biasing member provides a force on the retention member tending to disengage the retention member from the engagement member so that upon movement of the brake actuator to return the brake actuator from the second position to the first position, the retention member disengages from the engagement member enabling the brake actuator to be returned to the first position.

Dependent claims

A parking brake control assembly having a brake actuator movable between a first position and a second position, comprising:

an engagement member coupled to the brake actuator;
and
a control mechanism comprising:
a retention member that rotates about an axis;
a release actuator that moves relative to the retention member as the brake actuator moves between the first and second positions, the release actuator rotating about the same axis as the retention member;
and
a biasing member acting on the retention member and responsive to the movement of the release actuator,
wherein, in the first position of the brake actuator, the retention member is arranged to engage the engagement member upon movement of the brake actuator from the first position to the second position, and movement of the brake actuator from the first position to the second position causes the release actuator to move relative to the retention member such that the biasing member provides a force on the retention member that urges the retention member out of engagement with the engagement member.
