Pad Retraction Device

View page
US Patent:
8376092, Feb 19, 2013
Filed:
Feb 10, 2011
Appl. No.:
13/024357
Inventors:
Brad Robert Lethorn - Northville MI, US
Assignee:
Akebono Brake Corp. - Farmington Hills MI
International Classification:
F16D 55/22
US Classification:
188 723, 188 7338
Abstract:
A device comprising: a pair of opposing legs; a bridge between and connecting the pair of legs; a pair of retraction spring arms attached to the outside of each of the legs; the retraction spring arms each comprising: a guide support tab connected to each of the pair of opposing legs wherein the retraction spring arms assist in retracting a pair of brake pads, and the guide support tabs guide the retraction spring arms during movement.

Pad Retraction Spring For Disc Brake Assembly

View page
US Patent:
6378665, Apr 30, 2002
Filed:
Jun 30, 2000
Appl. No.:
09/607725
Inventors:
Christopher O. McCormick - Novi MI
Charles Giacomazza - Royal Oak MI
Brad R. Lethorn - Novi MI
Daniel P. Schneider - Plymouth MI
Assignee:
Kelsey-Hayes Company - Livonia MI
International Classification:
F16D 5522
US Classification:
188 723, 188 7338
Abstract:
This invention relates to a pad retraction spring for use in a disc brake assembly. The pad retraction spring is operative to move the friction pads from engagement with the rotor when the friction pads are in a non-braking position. The pad retraction spring is effective to apply a first force against the friction pads when the friction pads are new, and effective to apply a second force against the friction pads when the friction pads are worn. The second force is greater than the first force, and at least one of the first force and the second force by itself is not sufficient to move at least one of the friction pads from engagement with the rotor when the friction pads are in the non-braking condition.

Retraction Spring Assembly For Brake System

View page
US Patent:
20190085921, Mar 21, 2019
Filed:
Sep 21, 2017
Appl. No.:
15/711493
Inventors:
- Tokyo, JP
Brad Robert Lethorn - Northville MI, US
International Classification:
F16D 65/097
Abstract:
A retraction spring having: a) a bias device which stores energy during a brake apply and releases the energy during a brake release b) an anchor arm integrally attached at the support side arm of the bias device; c) a retraction arm integrally attached at the pad side arm of the bias device; wherein the loop axis lies within and is generally parallel to a transverse plane; wherein during the brake apply, movement of the retraction arm is away from the bias device, away from the anchor arm, and/or toward a rotor and results in the energy being stored in the bias device; and wherein during the brake release, the energy stored in the bias device is released and transferred to the retraction arm to result in movement of the retraction arm toward the bias device, toward the anchor arm, and/or away from the rotor.
