BRAKE LIQUID-PRESSURE CONTROL DEVICE

摘要

To efficiently make a brake fluid pressure control device compact and lightweight. A brake fluid pressure control device 10 includes: a block-shaped housing 30, inside of which are respectively formed a front wheel-use flow path 11 and a rear wheel-use flow path 21, with plural mounting holes being formed in each side surface of the housing 30; a pair of front wheel-use switching valve bodies 1a and 2a that are mounted in a pair of mounting holes 31a and 31b formed in a first side surface 30a that forms a substantially square shape of the housing 30, with the front wheel-use switching valve bodies 1a and 2a controlling the pressure of a brake fluid supplied to a front wheel-use wheel cylinder 103; a pair of rear wheel-use switching valve bodies 3a and 4a that are mounted in a pair of mounting holes 31c and 31d formed in the first side surface 30a of the housing 30, with the rear wheel-use switching valve bodies 3a and 4a controlling the pressure of the brake fluid supplied to a rear wheel-use wheel cylinder 106; a pressure sensor 13 that is inserted inside a mounting hole 31j in the first side surface 30a of the housing 30; and an electronic control unit 8 that drives and controls the front wheel-use and rear wheel-use switching valve bodies 1a to 4a.
