Abstract

A brake hydraulic pressure control device ( 2 ) controls a fluid pressure of a brake fluid supplied to wheel cylinders mounted on brake calipers ( 107, 114 ) of a motorcycle ( 100 ). The brake hydraulic pressure control device ( 2 ) includes: a base body in which flow passages are formed; and valves which open or close the flow passages. The base body is fixed below a spring in connecting portions ( 130 A, 130 B) which connect a trunk portion ( 101 ) of the motorcycle ( 100 ) and a wheels (front wheel ( 106 ), rear wheel ( 113 )) to each other.

First claim

The invention claimed is:

1. A brake hydraulic pressure control device for controlling a fluid pressure of a brake fluid supplied to a wheel cylinder mounted on a brake caliper of a motorcycle, the brake hydraulic pressure control device comprising:
a base body in which a flow passage is formed; and
a valve which opens or closes the flow passage, wherein
the base body is fixed below a spring in a connecting portion which connects a trunk portion of the motorcycle and a wheel to each other, wherein the base body and valve are positioned inside a wheel rim of the wheel, wherein the wheel rim has an axis of rotation, a lateral extent in the direction of the axis of rotation, and a radial extent, and the base body and valve are within the both the lateral extent and the radial extent.

2. The brake hydraulic pressure control device according to claim 1 , wherein the base body is fixed to the brake caliper.

3. The brake hydraulic pressure control device according to claim 1 , wherein the base body and the valve are positioned at a portion other than a primary ground contact portion of the motorcycle.

4. The brake hydraulic pressure control device according to claim 3 , wherein the base body and the valve are positioned at a portion other than a secondary ground contact portion of the motorcycle.

5. The brake hydraulic pressure control device according to claim 1 , wherein a controller of the valve is arranged on the trunk portion.

6. The brake hydraulic pressure control device according to claim 1 , further comprising a valve case which houses the valve therein, wherein
a region of a power source line for the valve arranged inside the valve case and a region of the power source line for the valve arranged outside the valve case are connected to each other not by means of a connector.

7. The brake hydraulic pressure control device according to claim 1 , further comprising a protective cover which covers at least a portion of the base body and the valve.

8. The brake hydraulic pressure control device according to claim 1 , wherein the base body includes: a first surface in which a valve hole for housing the valve is formed; a second surface in which a master cylinder port communicating with a master cylinder and a wheel cylinder port communicating with the wheel cylinder are formed; and a third surface in which an accumulator port communicating with an accumulator is formed.

9. The brake hydraulic pressure control device according to claim 8 , wherein the first surface, the second surface and the third surface are orthogonal to each other.

10. The brake hydraulic pressure control device according to claim 1 , wherein the wheel is a front wheel.

11. The brake hydraulic pressure control device according to claim 1 , wherein the wheel is a rear wheel.

12. An anti-lock brake system comprising the brake hydraulic control device described in claim 1 .

13. The anti-lock brake system according to claim 12 , wherein the anti-lock brake system is a pumpless anti-lock brake system.
