  • Brake cylinder for a rim brake
    Patent number: 6374957
    Abstract: The invention relates to a brake cylinder (100) and a hydraulic rim brake comprising a unit for receiving a brake pad (103). With known brake cylinders, it is difficult to remove the running wheel if the tire mounted on the wheel rim (6) is substantially wider than the wheel rim (6), since the wheel has to be moved through the gap between the two brake pads arranged on the brake cylinder. The brake cylinder according to the invention should have a simple structure and permit easy removal of the running wheel. The brake cylinder (100) according to the invention has a connecting member (302) for the arrangement of the brake cylinder (100) on a frame part (2″) in a manner rotatable about an axis, the axis being essentially orthogonal to the receiving unit for the brake pad (103).

  • Hydraulic rim brake for bicycles
    Patent number: 4585094
    Abstract: The invention relates to a hydraulic rim brake for bicycles with a triggering mechanism which is attached to the handlebar of the bicycle and is actuated by a hand lever, with two brake cylinder housings which are attached to the frame of the bicycle in oppositely located relationship to each other and enclose between them a wheel rim, the brake cylinder housings being connected by pressure lines to the triggering mechanism, with pistons displaceable in the brake cylinder housings, and with brake shoe supports arranged on these pistons for supporting brake shoes engaging the rim. In order to protect the piston from the effect of harmful bending moments, provision is made for the brake shoe supports to be in the form of flanges which are connected to the piston and are each displaceable parallel to the motion of the brake piston in a slide guide provided on the brake cylinder housing, and for the slide guide to simultaneously constitute abutments for absorption of the braking forces.
