Anti-Lock Braking System With Electromagnetic Brake
view source
US Patent:

50005235, Mar 19, 1991
Filed:

May 17, 1989
Appl. No.:

7/352971
Inventors:

Robert J. Hammersmith - Rochester Hills MI
Kevin G. Leppek - Troy MI
Paul D. Wilkey - Vandalia OH
Thomas H. Gardner - Englewood OH
Dennis J. Ricker - Huber Heights OH
James J. Kowalik - West Carrollton OH
Assignee:

General Motors Corporation - Detroit MI
International Classification:

B60T 842
US Classification:

303115
Abstract:

A vehicle wheel anti-lock braking system (ABS) is provided including a master cylinder and a wheel brake. An ABS controller cognizant of the rotational condition of the wheel provide a signal when the wheel condition is within preset parameters. An isolation valve responsive to close upon an activation signal given by said controller prevents fluid communication between the master cylinder and the wheel brake. An actuator frame is also provided having a bore fluidly communicating with the wheel brake. A piston is mounted within the bore for providing a variable control volume in communication with said wheel brake for and modulating the pressure therein. A reversible motor reciprocally powers piston. The motor has a rotor with a connected disc. A friction surface is provided for engagement with the disc to lock the position of the piston.

Filed:

Appl. No.:

7/669144
Inventors:

Robert J. Hammersmith - Rochester Hills MI
Kevin G. Leppek - Troy MI
Paul D. Wilkey - Vandalia OH
Thomas H. Gardner - Englewood OH
Dennis J. Ricker - Huber Heights OH

International Classification:

B60T 842
US Classification:

303115EC
Abstract:

A vehicle wheel anti-lock braking system (ABS) is provided including a master cylinder and a wheel brake. A controller cognizant of the rotational condition of the wheel provides a signal when the wheel condition is within preset parameters. An actuator frame is also provided having a bore fluidly communicating with the wheel brake. A piston is mounted within the bore for providing a variable control volume in communication with the wheel brake and for modulating the pressure therein. A reversible motor reciprocally powers the piston. The motor has a rotor with a connected disc. A friction surface is provided for engagement with the disc to lock the position of the piston. A plunger is also provided to urge the friction surface into engagement with the disc. An electromagnetic core, responsive to a signal by the controller, moves the plunger to a position allowing cessation of engagement between the friction surface and the disc thereby allowing rotation of the motor and movement of the piston.

US Patent:

20050040611, Feb 24, 2005
Filed:

Aug 21, 2003
Appl. No.:

10/646649
Inventors:

Scott Williston - Rochester Hills MI, US
Alan MacDonald - Novi MI, US
James Kowalik - Commerce Twp. MI, US
International Classification:

B60G017/00
US Classification:

280006159, 177137000
Abstract:

A payload monitoring system for a vehicle includes a first spring device and a first pressure transducer. The first pressure transducer generates a first pressure signal based on a pressure of the first spring device. A controller determines a payload of the vehicle based on the first pressure signal. The controller indicates the payload to an operator. The controller signals a warning if the payload is greater than a payload threshold.
