Filed: 1988-01-23
Abstract: PURPOSE:To effectively avoid a lock phenomenon of a wheel through an output lever mechanism by a low-priced device by overrun-rotating a fly wheel to operate a cam mechanism when a wheel is about to be locked during braking. CONSTITUTION:In a motorcycle, when a front master cylinder is operated to brake a front wheel, the output oil pressure is supplied to a front wheel brake 35 to clamp a brake disc 12, whereby braking is applied. Whereupon, angular deceleration is generated in a front wheel 2f, and a fly wheel 75 which senses the deceleration is about to overrun-rotate with respect to an output shaft 84 by its inertia force. At this time, when a wheel is apt to lock, both cam plates 96, 97 are relatively rotated, a thrust ball 98 rolls to displace a driven cam plate 97 and the fly wheel 75 in the axial direction. Thus, a lever 106 is oscillated to close a cutoff valve 20, so that braking oil pressure is lowered through a modulator (not shown).
