Abstract
Abstract A wheel hub assembly for a motorcycle has a fixed spindle and a boss rotatable about the spindle. A plate forming a brake disc projects radially from the boss and carries the wheel supporting structure on its outer periphery. Secured on the spindle, one to each side of the boss, are two members carrying opposed hydraulic cylinders. The cylinders apply brake blocks to the two faces of the brake disc.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
114 words
A wheel hub assembly for a motorcycle having a spindle to be non-rotatably secured to a motorcycle frame and, supported on the spindle by bearings for rotation, a wheel boss from which extends radially a plate having parallel faces and constituting a brake disc having a periphery which carries structure by which a wheel is attached to the hub assembly, there being rigidly secured to the spindle, one to each side of the wheel boss, two members carrying opposed hydraulically actuated cylinders adapted to be connected with an external brake control circuit and provided with pistons carrying brake blocks which on operation of the cylinders engage with respective opposed faces of the said disc.
