Abstract
A brake stem for a motorcycle in which the operation of the front and rear brakes is synchronized. A front brake caliper is attached to a bracket on the front wheel. The braking force on the caliper is transmitted to a master cylinder via the bracket, and serves to compress the master cylinder. The master cylinder includes an outlet which transmits pressurized hydraulic fluid from the master cylinder to a rear brake.
Claims20
A brake system for a motorcycle having a suspension for a front wheel, the front wheel having a front brake disc, the system comprising:
- a first bracket swingably mountable to an axle of the front wheel;
- a second bracket swingably mounted to the first bracket, the second bracket being positioned behind a front fork;
- a caliper mounted to the second bracket, the caliper being for operating the front brake disc;
- a torque transmitting unit operably connected to the second bracket, the torque transmitting unit generating hydraulic pressure in response to a braking reaction force applied to the bracket;
- a mudguard connected to the second bracket, the mudguard being movable with the axle of the front wheel;
- and
- a rear brake, the rear brake being responsive to the hydraulic pressure generated by the torque transmitting unit.
The brake system of claim 5, further comprising:
- hydraulic piping connecting an outlet of the master cylinder to the rear brake;
- and
- a proportional control valve arranged in series with the hydraulic piping.
A brake system for a motorcycle comprising:
- a front brake for exerting a braking force on a front wheel of the motorcycle;
- a front brake actuator for actuating the front brake;
- a bracket which is mountable to an axle of the front wheel, the bracket being positioned behind a front fork;
- a torque transmitting unit, the torque transmitting unit being operatively connected to the front brake, and responsive to a braking reaction force exerted by the front wheel on the front brake;
- a mudguard, the mudguard being operatively connected to the bracket;
- and
- a rear brake for exerting a braking force on a rear wheel of the motorcycle, the rear brake being responsive to the torque transmitting unit to exert the braking force on the rear wheel.
A motorcycle comprising:
- a body frame;
- a front wheel;
- a rear wheel;
- a bottom link front wheel suspension including:
- a front fork;
- front wheel support arms connected to distal ends of the front fork, the front wheel support arms being engaged with an axle of the front wheel;
- a rod, the rod having a lower end and an upper end, whereby the lower end being swingable coupled to the front wheel support arms;
- an arm being longitudinally swingable, the arm extending forward from a bottom bridge in order to connect the upper end of the rod;
- and
- spring/damper units coupled to the arm;
- and
- a brake system including:
- a bracket engaged with the axle of the front wheel, the bracket being positioned behind the front fork;
- a caliper for exerting a braking force on the front wheel, the caliper being supported on the bracket;
- a mudguard connected to the bracket;
- and
- a torque transmitting unit, the torque transmitting unit being operably connected at one end to the bracket, and at another end to the front fork.
