Embodiment Construction

[0029] A control unit B of a hydraulic brake apparatus for a vehicle according to an embodiment of the present disclosure will be described with reference to the drawings. The control unit B includes: a first piping system for controlling the brake hydraulic pressure applied to the left front wheel and the right rear wheel; and a second piping system for controlling the brake pressure applied to the right front wheel and the left rear wheel hydraulic. Since the configuration of the first piping system is similar to that of the second piping system, only the configuration of the first piping system will be described, and the description of the second piping system will be omitted.

[0030] First, based on figure 1 The overall configuration of the vehicle hydraulic brake apparatus A having the control unit B will be described. The hydraulic brake apparatus A for a vehicle is constituted by a master cylinder 10 , wheel cylinders WCfl and WCrr, a control apparatus 60 , and a co...

Abstract

A control unit of a hydraulic brake apparatus for a vehicle including a housing, a switching control valve, pressure increase control valves, pressure decrease control valves, a reservoir, a pump driven by a motor, a first passage, a second passage, an inner bore and a passage forming member being liquid-tightly fitted into the inner bore in order to form an extended ring-shaped passage, wherein the extended ring-shaped passage forms a part of the first passage, and the switching control valve, the pressure increase control valves and the outlet valve are connected to the extended ring-shaped passage, and a part of the second passage is formed within the passage forming member, and end portions of the part of the second passage are connected to the switching control valve and the switching valve.

Description

technical field [0001] The present disclosure relates to a control unit of a hydraulic brake apparatus for a vehicle by which brake hydraulic pressure is automatically applied to wheel cylinders during antiskid control, sideslip control (eg, electronic stability control), traction control, and the like. Background technique [0002] As an example of a control unit of a hydraulic brake apparatus that automatically applies hydraulic pressure to wheel cylinders, there is known, for example, a control unit disclosed in JPH11-208440A, which has a housing in which is integrally formed a Holes for control valves, communication passages for control valves, etc. [0003] In view of the space efficiency in the control unit and the connection efficiency of the pipes connected to the outside of the housing, such a control unit has such a structure that the master cylinder port and the wheel cylinder port are arranged at the upper part of the housing; The lower part; while the pump, con...
