US 5,564,534 A · Link between a motorcycle brake caliper and a master cylinder

Abstract

Links are provided for linking a brake caliper pivotally supported through a pin to a vehicle body. A master cylinder is fixed to the vehicle body and is constructed of a first link having one end pivotally supported through a pin to the brake caliper and the other end pivotally supported through a pin to an input member of the master cylinder. A second link is provided having one end pivotally supported through a pin to the vehicle body and the other end pivotally supported through a pin to the first link at an intermediate portion thereof. When the brake caliper is swung in a first direction by a brake reaction force received from a brake disc, the input member is upwardly driven through the first link and the second link, and the master cylinder is operated to generate a secondary brake hydraulic pressure.

Dependent claims

A brake for a motorcycle comprising:

a brake disc operatively affixed for rotation with a wheel;
a brake caliper pivotally supported relative to a support, said brake caliper being selectively actuated for engaging said brake disc;
a master cylinder for generating a brake hydraulic pressure;
and
linking means for transmitting a pivotal motion of said brake caliper to an input member of said master cylinder;
said linking means comprising a first link having one end pivotally supported relative to said brake caliper and the other end pivotally supported relative to said input member, and a second link having one end pivotally supported relative to said support and the other end pivotally supported relative to a central portion of said first link.
