Title:
BRAKE LIQUID PRESSURE CONTROL DEVICE
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.
