Wheel Slip Protection System
US Patent:
2011011, May 19, 2011
Filed:
Nov 13, 2009
Appl. No.:
12/618285
Inventors:
Thomas S. Head - Greenville SC, US
James D. Wasness - Inman SC, US
James D. Wasness - Inman SC, US
International Classification:
B60T 8/58
US Classification:
303132
Abstract:
An anti-locking brake module comprises a housing having a first port coupled to a brake pipe, a second output port coupled to a brake cylinder, and a third port coupled to atmosphere. A blocking valve is in fluid communication with the first port and a vent valve is in fluid communication with the blocking valve, the second port and the third port. At least one sensor is coupled to an axle on the railcar. A microprocessor coupled to the blocking valve, the vent valve and the at least one sensor is configured to calculate one of a wheel speed of the railcar axle and a deceleration rate of the railcar axle based on signals received from the at least one sensor, and compare the calculated one of the wheel speed of the railcar axle and the deceleration rate of the railcar axle with a reference value. In response to the comparison, the blocking valve and the vent valve are activated to vent brake cylinder air pressure out of the third port. A power supply is operatively coupled to the microprocessor.
Electrically Operable Vehicle Parking Brake Drive
US Patent:
6913325, Jul 5, 2005
Filed:
Sep 11, 2003
Appl. No.:
10/660351
Inventors:
Mark Michel - Greer SC, US

Assignee:
Ellcon National, Inc. - Greenville SC
International Classification:
B60T013/74
US Classification:
303 2, 303 20, 188 34, 188162
Abstract:
An electrically or manually operable brake drive for the brakes of a vehicle which has a gear train optionally driven by a reversible electric motor or a manual member. The brakes can be set or released by the electric motor without manual changing of the drive components permitting setting and releasing of the brakes at a location remote from the drive. For maintaining the brakes in a “set” mode, the drive includes a gradual release detent mechanism which permits rotation of the gears in the brake setting direction but opposes such rotation in the opposite direction unless a drive shaft rotatable by the motor or the manual member is rotated in the brake release direction.
Vehicle Brake Status Indicating Apparatus
US Patent:
6112860, Sep 5, 2000
Filed:
Feb 5, 1999
Appl. No.:
9/245628
Inventors:
Robert W. Shepherd - Pelzer SC
James D. Wasness - Inman SC
James D. Wasness - Inman SC
Assignee:
Ellcon-National, Inc. - Greenville SC
International Classification:
F16D 6600
US Classification:
188 111R
Abstract:
In a vehicle braking system having a slack adjuster with an actuator and an electrically operable car control unit, an electrical switch is responsive the position of the actuator and is coupled to the car control unit to provide an indication of the condition of the vehicle brake shoes, i. e. whether or not the brake shoes are disengaged from the vehicle wheels.
