Abstract

The purpose is to decrease the physical size of a brake fluid pressure control apparatus for implementing pressure increasing / decreasing control for the fluid pressure in a wheel cylinder. A brake fluid pressure control apparatus is provided with: a piston pump (5); a pump drive motor (3); an eccentric cam rotated by the motor to activate the piston pump; a pressure-increasing electromagnetic valve (6); and a pressure-decreasing electromagnetic valve (7), in which the piston pump (5), the eccentric cam, the pressure-increasing electromagnetic valve (6), and the pressure-decreasing electromagnetic valve (7) are assembled in a housing (1a). The single piston pump (5) is installed, with the piston pump (5), when mounted on a vehicle, disposed in an upright posture under or above a cam chamber (11) of the housing in which the eccentric cam is housed.

Description

technical field [0001] The present invention relates to a brake hydraulic pressure control device including a motor-driven pump used in a hydraulic brake device of a vehicle. Background technique [0002] A brake hydraulic pressure control device for a vehicle is arranged in a hydraulic path from a master cylinder to a wheel cylinder, and controls the increase and decrease of the hydraulic pressure of the wheel cylinder for the purpose of avoiding wheel locking. As an example, there is the content disclosed in the following patent document 1, for example. [0003] The brake hydraulic pressure control device disclosed in this document is provided with an eccentric cam and a piston pump, and the piston pump is driven and operated by a motor that rotates the eccentric cam as a power source. There are two sets of the piston pumps, and the two sets of piston pumps are respectively arranged in the front wheel system and the rear wheel system of the two-wheeled vehicle. [0004] ...
