Publication number: 20120137485Abstract: The invention concerns in particular a lining-holder cartridge for a drum brake equipped with shoes comprising a block provided with a rim for fixing a friction lining, the assembly forming a shoe for a drum brake, wherein it comprises a curved support in the form of a cylinder sector able to be fixed directly to the rim of said block, and it is provided with a friction lining with a shape adapted to that of said support. The invention greatly simplifies the replacement of drum brake linings, without removal of the brake blocks.Type: ApplicationFiled: December 3, 2009Publication date: June 7, 2012Applicant: SONOMEV FREINS (S.A.S.)Inventor: Gerard Ricci

Patent number: 8104590Abstract: A railcar brake head having an upper end, a lower end, and a pair of sides. The brake head further includes an elongated concave keyway defining an elongated axis and opening to the upper and lower ends of the brake head. At least a portion of the keyway is defined between a rear wall and spaced transversely extending upper and lower lugs. A front surface of each lug is adapted for mounting engagement with a brake shoe. The longitudinal spacing between the centralized upper and lower lugs is such that a keybridge extending from a rear face of the brake shoe is received and accommodated therebetween whereby inhibiting endwise movement of the brake shoe relative to the brake head.Type: GrantFiled: June 7, 2007Date of Patent: January 31, 2012Assignees: Powerbrace Corporation, Miner Enterprises, Inc.Inventors: Rudolph S. Fortuna, Joseph Centeno

Patent number: 6938739Abstract: A brake head positioning means for railcar braking systems. The brake head positioning means is comprised of an attachment means that is engageable with a railcar hanger arm for attaching such brake head positioning means to such railcar hanger arm. An extension means that is engageable with and extends substantially perpendicular to and outwardly from such attachment means is also included. The extension means provides sliding engagement and enables a biasing force to be achieved. Also included is a variable distancing means which is disposed for sliding engagement with and is substantially perpendicular to such extension means adjacent a first end thereof, and is engageable with a brake head adjacent a second end thereof. A biasing means, disposed around and slideably engageable with such extension means for providing a bias to such variable distancing means during service is further included.Type: GrantFiled: December 26, 2002Date of Patent: September 6, 2005Assignee: Westinghouse Air Brake Technologies CorporationInventors: Frank J. Korleski, Roland S. Moore

Patent number: 6732841Abstract: A rail vehicle bogie brake has a brake beam (4, 5). Which at its end is provided with a brake block holder (8) having a brake block (9) for brake application against a tread of a wheel. The brake block holder has a transverse cylinder (19) for its pivotable connection with the brake beam. A mounting shaft (14) is attached in the end of the brake beam and is provided with a sleeve (16). The sleeve engages the mounting shaft and has an outer diameter corresponding to the inner diameter of the cylinder. A sleeve plate (17) is held against the sleeve, which is slightly longer than the cylinder, by means of screws (18) attached in the mounting shaft and prestressing the sleeve.Type: GrantFiled: August 7, 2002Date of Patent: May 11, 2004Assignee: Sab Wabco ABInventors: Fred Emilsson, Johan Nyman

Patent number: 6176354Abstract: A truck mounted rail brake including at least a primary beam having a center section and a pair of end sections with guide end extensions. A brake head is removably mounted to the end sections by a pin. The pin is dimensioned to allow pivotal movement of the brake head about the pin. The pin is retained in the brake head by either a tab or another pin above and transverse to the first pin.Type: GrantFiled: January 29, 1999Date of Patent: January 23, 2001Assignee: New York Air Brake CorporationInventors: Jeffrey F. Sauter, Robert Gayfer, Zdzislaw Samulak
