摘要:
A straddle-type vehicle includes an input shaft connected to a rear drive shaft and extending in a front-rear direction of the vehicle, an output shaft connected to an axle and configured to rotate by receiving a driving force from the input shaft, a brake operator on which an operation is performed to brake the input shaft, a plate group disposed between a wall portion of a housing and a cam member, a cam plate disposed between the cam member and the plate group, an operation shaft extending in a direction perpendicular or substantially perpendicular to an axial direction of the input shaft, a first engagement protrusion protruding from the cam plate, a second engagement protrusion protruding from the operation shaft and engaging with the first engagement protrusion, a lever rotatable together with the operation shaft, and an operation cable connected to the brake operator and the lever.

A brake roller may comprise a brake shaft and a brake stack assembly located around the brake shaft. A one-way jaw clutch assembly may be configured to apply a force to the brake stack. A roller shell may be located radially outward of the brake stack. The one-way jaw clutch assembly may be configured to vary the force applied to the brake stack in response to a rotation of the roller shell in a circumferential direction.

A plurality of stationary metallic discs are alternately arranged with and selectively moved into and out of braking engagement with a plurality of rotating friction discs. A rotatable member carrying an adjustable pin is movable axially to move the pin into engagement with a pressure arm which acts on the stationary discs to set the brake by interengagement of the stationary and rotating discs. The rotatable member includes a cam surface which engages a fixed cam guide such that, as the rotatable member is rotated, the member and pin move jointly in an axial direction with respect to the discs. The cam surface includes a first rise portion for rapid and relatively greater axial travel during initial brake movement to take up the release or running clearance. The cam also includes a relatively shallow rise portion to provide a gradual application of a relatively high brake setting force with reduced axial travel after the release clearance has been taken up. A ratchet and pawl arrangement provides for axial adjustment of the pin with respect to the disc to compensate for disc wear. The brake actuator is of the spring set and electromagnetically released type and includes a manual release. A damper is included in the actuator and is adjustable to provide for adjustment of the brake setting time independent of setting torque. The damper also prevents overriding of the cam guide and surface as the brake is set.

The present invention provides a wheel hub for a vehicle, including: a) a wheel axle defining an axis of rotation for the wheel; b) a hub body rotatably coupled to the axle for rotation about the axis of rotation, the hub body defining an internal cavity; and, c) a braking assembly, including: i) at least one first annular plate disposed within the internal cavity about the axle, the at least one first annular plate rotatably fixed with respect to the hub body so as to rotate therewith about the axis of rotation; ii) at least one second annular plate disposed within the internal cavity about the axle and adjacent to the at least one first annular plate, the at least one second annular plate rotatably fixed with respect to the axle, and at least one of the first and second annular plates being slidably movable within at least part of the internal cavity; and, iii) an actuator disposed within the internal cavity and configured in use, to cause an axial load to be applied to the slidably movable plate to thereby cause the at least one first and second annular plates to frictionally engage thereby applying a braking load between the hub body and wheel axle so as to brake the wheel of the vehicle.
