Abstract:
A brake caliper (12) includes a housing having at least one bore formed therein. A coolant passage (22) is formed through the housing and extends radially outwardly from the bore and is fluidically coupled thereto. The coolant passage (22) can accept a coolant, which can be actively moved or it can be passively moved. The brake caliper (12) also has at least one piston (16) slidably mounted in the bore. The piston can be made from a thermally conductive material. The piston (16) can include a wall that is thicker at a first end there of than at the second end thereof . The thicker end is that which contacts a brake pad. A method of cooling a disc brake assembly is also provided. The coolant passage takes heat out of the disc brake assembly before it reaches the brake fluid. Heat is dissipated by thermal exchange into the caliper, coolant, and/or the atmosphere.

Abstract:
A wheeled riding device has a body with an elongate front arm, a turning tail, and a joint part pivotally connecting the turning tail and front arm relative to one another. A front wheel is carried by a forward end of the front arm. Rear wheels are carried by a rear end of the turning tail. A standing platform is supported over the front arm and turning tail. The rear wheels and turning tail can pivot laterally side to side relative to the front arm. The front wheel and front arm can pivot vertically up and down relative to the standing platform. The front wheel, during a turn, is cambered inward into the turn. The device is controlled by the rider using body movements and skills required to ride a snowboard.
Abstract:
The brake housing (12) comprises a first portion (14), a second portion (16), and a demountably coupled cylinder block (18). The first and second portions (14, 16) comprise respective openings (40, 68) through which a rotating component passes. The portions (14) and (16) are coupled together to define an internal space about a portion of the rotating body. One or more cylinder blocks (18) are formed separately of the first and second portions (14, 16) and directly demountably coupled to the first or second portions. Each cylinder block (18) is provided with a first surface (28) that faces the portion (14, 16) to which the cylinder block is coupled. Each block (18) is also provided with one or more cavities (20) that open onto an opposite surface (22) of the cylinder blocks (18) for receiving respective pistons (24). The blocks (18) can be fixed at any location inside the housing (12) to meet the requirements of the associated brake assembly at hand.
Abstract:
A braking device 10 comprises a calliper 11 intended to run alongside a friction track P, a housing 12 in this calliper into the bottom of which housing there open hydraulic connection ports 13A and 13B, one of these hydraulic connection ports being situated centrally with respect to this bottom of the housing, a piston 14 slideably mounted in this housing and equipped at one end with a brake pad 17 and comprising a cavity 8 opening at the other end facing the bottom of the housing, a hollow central rod 21 fixed to the bottom of this housing in the continuation of the hydraulic connection port 13A situated in a central position and comprising a stepped head 22 at an end situated inside the cavity and a stack of Belleville washers 23 compressed between this stepped head and a flange 9 protruding from the internal wall of the cavity, radially toward the central rod, and secured to this piston, this stack being designed to ensure total recoil of the piston toward the bottom of the housing, until it reaches a configuration in abutment with respect to the bottom of the calliper, as the brake pressure reduces.
Abstract:
A park brake (14) is incorporated into a housing (10) of a disc brake system (12). The housing (10) is in the form of an annular ring having a plurality of cavities (16) for housing service brake pistons which act on brake pads (18) to selectively force the brake pads (18) onto a brake disc to produce a surface brake effect. The park brake (14) includes an actuator (23) supported by the housing (10) which is switchable between an applied state where it forces the brake pad (18) into contact with the brake disc of the system (10) independent of the action of the service brake pistons to produce a park brake effect, and a released state where the actuator (23) allows the brake pad (18) to become disengaged from the brake disc. The actuator (23) includes a hydraulically operated park brake piston (27) having a rod (24) extending therefrom. The rod (24) is slidably retained within a hole (26) formed in the housing (10) and is arranged to abut or otherwise apply force to the brake pad (18). When fluid pressure is applied to the pad brake piston (27) it retracts the rod (27) into the housing (10) releasing the park brake (14). In the absences of the application of fluid pressure, a spring (34) of the actuator (23) operates to switch the actuator (23) to an applied state where the rod (24) pushes on the pad (18) forcing it into contact with the brake disc thereby providing the park brake effect.
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 disassemble the running wheel if the tire mounted on the wheel rim (6) is significantly 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 cylinders. The aim of the invention is to provide a brake cylinder which has a simple structure and permits easy disassembly of the running wheel. To this end the brake cylinder (100) has a connecting member (302) for mounting said brake cylinder (100) on a frame part (2") in such a way that it is able to pivot about an axis situated substantially orthogonally to the element for receiving the brake pad (103).
