Title: Hub clutch unit
Inventor: ITO KENICHIRO
IPC: F16D41/10
Filed: 1993-06-10
Abstract: PURPOSE:To enable selection of the engagement and vice versa between a front-wheel axle and a wheel hub automatically according to their speed differences. CONSTITUTION:A retainer 8 holding a roller 12 is installed in space between an inner ring 2 to lee connected to a front axle 50 and an outer ring 1 to be connected to a wheel hub 52, and this retainer 8 and the inner ring 2 are connected to each other via a clearance in a direction of rotation. A torsional coil spring 17 producing a rotational resistance is attached to one end of the retainer 8, and a rotational resistance imparting means 20 is connected to the other end via a one-way clutch 18. when the front axle is rotated to the wheel hub, the one-way clutch 18 is raced in the case of going forward, whereby the roller 12 is engaged in a state of being on forward standby. In the case of backward in reverse, the one-way clutch 18 is locked, phase of the retainer 18 varies as far as a portion for the rotational direction clearance by the rotational resistance acting on the retainer 18, so that the roller 12 comes to a state of being engaged in the opposite direction against the forward direction. Conversely, rotation of the wheel hub is speedier than that of the front axle, the outer ring overruns on a sprag, so its engagement comes off.
