Document Type and Number:
WIPO Patent Application WO/2008/029600
Kind Code:
A1
Abstract:
Intended is a brake liquid pressure control device capable of dissipating the heat, which is generated from an electronic control unit, efficiently and in a space-saving manner. The brake liquid pressure control device comprises a hydraulic unit (12), a coil unit (14) and an electronic control unit (16). The hydraulic unit (12) includes an electromagnetic change-over valve body (26a-h) for switching the flow of a brake liquid to flow in a passage (24), and a hydraulic housing (28) having a passage formed therein for holding the electromagnetic change-over valve. The coil unit (14) includes a coil (38a-h) for activating the electromagnetic change-over valve body, and a coil housing (42) for holding a coil. The electronic control unit (16) includes an electronic part (20a-d) for controlling the electromagnetic change-over valve body and the coil, and a circuit board (22) having the electronic part mounted therein. The hydraulic unit is arranged on one side of the coil unit. The electronic control unit is arranged on the other side of the coil unit. The brake liquid pressure control device further comprises fastening means (18, 19) for fixing the hydraulic housing and the coil housing and for transferring the heat generated from the electronic part, to the hydraulic housing.
