Abstract
A rear wheel braking apparatus for a motorcycle wherein a rear fork with a rear wheel pivotally mounted on the rear end thereof is coupled to the frame of the motorcycle via a pivot shaft in a vertically swingable manner; a rear wheel drive device for coupling between the output shaft of an engine on the frame and the rear wheel is provided side by side with the rear fork; an anti-lock controlling unit for controlling the braking hydraulic pressure to be fed to the rear brake in response to the output from a built-in sensor is provided on the rear fork in the vicinity of the pivot shaft; and wherein the drive shaft of the sensor is coupled to the rear wheel drive device.
Claims16
In a motorcyle having a rear wheel pivotally supported on a rear end of a rear fork, said rear fork being coupled to a vehicle frame via a pivot shaft for vertical swinging motion, a rear wheel drive device for coupling between said rear wheel and an output shaft of an engine mounted on said vehicle frame being disposed side by side with said rear fork and being operable to indicate a rotational speed of said rear wheel,
- a rear wheel braking apparatus which comprises:
- a master cylinder installed on said vehicle frame;
- a rear wheel brake operable by an output hydraulic pressure of said master cylinder to apply a braking force to said rear wheel;
- and an anti-lock controlling unit incorporated with an inertia-type wheel angular deceleration sensor operatively conected with said rear wheel, said unit controlling a hydraulic pressure to be inputted to said rear wheel brake in response to an output from the sensor, wherein said anti-lock controlling unit is installed on said rear fork in close proximity to said pivot shaft, wherein a drive shaft of said sensor is coupled with said rear wheel drive device and wherein said master cylinder is disposed in a vicinity of said anti-lock controlling unit and hydraulically coupled therewith.
In a motorcycle having a rear wheel pivotally supported on a rear end of a rear fork, said rear fork being coupled to a vehicle frame via a pivot shaft for vertical swinging motion, a rear wheel drive device for coupling between said rear wheel and an output shaft of an engine mounted on said vehicle frame being disposed side by side with said rear fork, said rear wheel drive device being of a shaft drive type and being operable to indicate a rotational speed of the rear wheel, said rear fork having a fork leg with a hollow transmission chamber formed therein, a propeller shaft of said rear wheel drive device being housed in said transmission chamber,
- a rear wheel braking apparatus which includes a master cylinder installed on said vehicle frame;
- a rear wheel brake operable by an output hydraulic pressure of said master cylinder to apply a braking force to said rear wheel;
- and an anti-lock controlling unit incorporated with an inertia-type wheel angular deceleration sensor operatively connected with said rear wheel, said unit controlling a hydraulic pressure to be inputted to said rear wheel brake in response to an output from the sensor, wherein said anti-lock controlling unit is installed on said rear fork in close proximity to said pivot shaft, wherein a drive shaft of said sensor is coupled with said rear wheel drive device, said drive shaft of said sensor being coupled with said propeller shaft via a gear mechanism and wherein said master cylinder is disposed adjacent the anti-lock controlling unit and is hydraulically coupled therewith.
