Abstract
An automatic parking brake cable tension adjustment apparatus includes a first connecting member attached by a cable to a brake handle, a first pivoting member, a second pivoting member, a mechanical linkage between the first and second pivoting member, and a second connecting member attached by a cable to a parking brake. As the brake cable becomes extended past a certain point, the first pivoting member contacts a fixed stop and pivots, thereby pivoting the second pivoting member. A threaded connection between the second pivoting member and the second connecting member rotates, automatically adjusting the tension of the brake cable.
Claims8
A vehicle parking brake cable tension adjustment apparatus adapted for connection between a first parking brake cable portion extending from a brake lever and a second parking brake cable portion extending from a vehicle brake apparatus, comprising:
- a first connecting member adapted for attachment in axial alignment to the first parking brake cable portion;
- a first pivoting member connected to the first connecting member to pivot with respect to the first connecting member upon engagement with a fixed stop;
- a second pivoting member axially aligned with said first connecting member and pivotally connected to the first connecting member;
- a mechanical linkage linking the first pivoting member to the second pivoting member, configured so that the second pivoting member pivots only when the first pivoting member pivots upon engagement with the stop;
- and
- a second connecting member having two ends and being axially aligned with the first connecting member and the second pivoting member, the first end being pivotally connected to the second pivoting member, and the second end being attachable to the second parking brake cable portion extending from the vehicle brake apparatus.
The apparatus of clam 1, wherein the mechanical linkage includes a tooth projecting from the first pivoting member engaging a ratchet fixed to the second pivoting member.
A vehicle parking brake assembly, comprising:
- a brake handle
- a first brake cable portion protecting from the brake handle;
- a first connecting member attached in axial alignment to the first brake cable portion;
- a first pivoting member connected to the first connecting member to pivot with respect to the first connecting member upon engagement with a fixed stop;
- a second pivoting member axially aligned with and pivotally connected to the first connecting member;
- a mechanical linkage linking the first pivoting member to the second pivoting member, configured so that the second pivoting member pivots only when the first pivoting member pivots upon engagement with the stop;
- a second connecting member having two ends and aligned with the axis, the first end pivotally connected to the second pivoting member;
- and
- a second brake cable portion protecting from the second end of the second connecting member, and having a distal end adapted for attachment to a vehicle parking brake apparatus.
