  • Patent number: 5069312
    Abstract: A handbrake system for use with a truck-mounted, single-cylinder brake rigging including truss-type brake beams, there being a single handbrake pivotal lever supported intermediate its ends by a twisted transfer link that is, in turn, fixed to the brake rigging transfer lever. A fulcrum end of the handbrake lever is free to engage the bearing surface of a thrust block mounted on the brake beam at the juncture of the beam tension and strut members in order to allow the point of engagement between the fulcrum end and the bearing surface to change with rotation of the handbrake lever. In addition, the fulcrum end of the handbrake lever is arranged with two, spaced-apart arcuate segments that successively engage the bearing surface of the thrust block during rotation of the handbrake lever to change its lever ratio and, accordingly, limit the degree of rotation of the handbrake lever.
