US Patent:

7340977, Mar 11, 2008

Filed:

Feb 27, 2004

Appl. No.:

10/789973

Inventors:

David Leslie Agnew - Clarkston MI, US
Michael Charles Carr - Oxford MI, US

Assignee:

Continental Tevis, Inc. - Auburn Hills MI

International Classification:

G05G 1/14

US Classification:

74512

Abstract:

A brake mechanism includes a pedal arm, a beam and a cam. The pedal arm is pivotally connected to the vehicle, while the beam is interposed between the pedal arm and the input rod for transmitting force from the pedal arm to the input rod. The beam is pivotally connected to the pedal arm and rotatable relative thereto. The cam defines a cam profile, and the beam contacts the cam and follows the cam profile as the pedal arm is activated. The cam profile is shaped to adjust the position of the beam relative to the pedal arm as the pedal arm swings relative to the vehicle. In this way, a variable force ratio is provided to maintain brake pedal feel while achieving an acceptable force ratio for failed power situations. The mechanism can be designed such that the force ratio does not drop off further into the pedal travel.

Appl. No.:

10/445995

Inventors:

Michael Carr - Oxford MI, US
Philipp Weinschrod - Metamora MI, US

Assignee:

Continental Teves, Inc.

International Classification:

G05G001/14

US Classification:

074/560000

Abstract:

A brake activating mechanism for a vehicle is responsive to the required braking force to adjust the magnification of the manual input force, thereby providing greater assistance to the vehicle operator. The brake activating mechanism generally includes a pedal arm connected to a brake pedal for receiving the manual input force and connected to a pushrod for transmitting the output force. A clutch mechanism is employed that is responsive to the input force to modify the position of the pivot point. In this way, the magnification of the input force via the pedal arm is modified.
