  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  As shown in FIG. 1, the vehicle brake hydraulic pressure control device 10 </ b> B is released from the master cylinder 12 that pressurizes the hydraulic fluid according to the operation of the brake lever 11 and generates hydraulic pressure, and the front wheel caliper 14 side. A reservoir 13 that temporarily stores hydraulic fluid, an inlet control valve 15 that is a normally open solenoid valve and an outlet control valve 16 that is a normally closed solenoid valve provided between the master cylinder 12 and the front wheel brake caliper 14; A pump 17 that sucks the hydraulic fluid stored in the reservoir 13 and returns it to the master cylinder 12 side, a motor 29B that drives the pump 17, drive control of the motor 29B, and opening / closing control of the inlet control valve 15 and the outlet control valve 16 And a brake fluid path A1, B1, C1, D1, E1 that is provided in the base body 40B and allows the brake fluid to flow therethrough.

  The base body 40B includes an inlet port 12P to which a liquid path (brake pipe) extending from the master cylinder 12 is connected, and an outlet port 14P to which a liquid path (brake pipe) extending to the front brake caliper 14 is connected.

  Here, the brake fluid passage A1 is a fluid passage from the inlet port 12P to the inlet control valve 15, and the brake fluid passage B1 is a fluid passage from the inlet control valve 15 to the outlet port 14P. The brake fluid passage C1 is a fluid passage from the brake fluid passage B1 to the reservoir 13, and the brake fluid passage D1 is a fluid passage from the reservoir 13 to the pump 17. Further, the brake fluid passage E1 is a fluid passage from the pump 17 to the brake fluid passage A1.

Next, the operation of the vehicle brake fluid pressure control device 10B will be described.
ABS non-operating state: When there is no concern that the front wheels are locked, the control device 30B stops the pump 17 and opens the inlet control valve 15 and closes the outlet control valve 16. In this state, when the brake lever 11 is operated to the braking side, the hydraulic pressure is increased by the master cylinder 12, and this hydraulic pressure is transmitted to the front wheel brake caliper 14 via the inlet control valve 15.

ABS (decompression mode): When the front wheel is about to lock, the control device 30B closes the inlet control valve 15 and opens the outlet control valve 16. The hydraulic pressure in the front brake caliper 14 is released to the reservoir 13 via the outlet control valve 16. As a result, the brake fluid pressure of the front wheel brake caliper 14 is reduced.

ABS (holding mode): The control device 30B closes both the inlet control valve 15 and the outlet control valve 16. As a result, the brake fluid pressure of the front wheel brake caliper 14 is kept constant.

ABS (pressure increase mode): When increasing the brake fluid pressure, the control device 30B opens the inlet control valve 15 and closes the outlet control valve 16. As a result, the hydraulic pressure generated in the master cylinder 12 is transmitted to the front wheel brake caliper 14. As a result, the brake pressure of the front wheel brake caliper 14 is increased.

FIG. 2 is a plan view of the vehicle brake control device, and FIG. 3 is a sectional view taken along line 3-3 of FIG. FIG. 3 will be described first.
As shown in FIG. 3, the housing 36 includes a peripheral wall portion 84 formed with openings on the front (front) side and the back side, and a connector portion 37.
The electromagnetic valve 15 as an inlet control valve and the electromagnetic valve 16 as an outlet control valve include an electromagnetic coil 33. The electromagnetic coil 33 includes a yoke portion 86 having a flat side surface 86a.
The peripheral wall portion 84 has a rectangular shape and includes a chamfered portion 88 having at least one chamfered portion, and the two electromagnetic valves 15 and 16, the electromagnetic coils 33 and 33, and the motor 29 </ b> B are accommodated inside the peripheral wall portion 84. A storage chamber 89 is provided.

  The electromagnetic valves 15 and 16 are accommodated in the accommodating chamber 89 so that the side surface 86a of the yoke portion 86 and the chamfered portion 88 face each other. The interval between the adjacent yoke portions 86 and 89 can be increased. As a result, the distance between the coil connection terminals 128 and 128 extending from the electromagnetic coils 33 and 33 is increased, the area of the yoke portion 86 is increased, and the magnetic path area of the yoke portion 86 can be increased.

  Further, since the peripheral wall portion 84 of the housing 36 is chamfered, the clamp seat 97 at the time of processing can be provided on the base body 40B protruding from the peripheral wall portion 84 without increasing the base body 40B.

As shown in FIG. 2, in the vehicle brake hydraulic pressure control device 10 </ b> B provided with a base body 40 </ b> B and a housing 36 attached to one surface of the base body 40 </ b> B, a motor (FIG. 3, reference numeral 29 </ b> B) is housed in the housing 36. In addition, a control board (reference numeral 99 in FIG. 4) is housed.
The electrical connection structure between the motor and the control board will be described in detail below.

  As shown in FIG. 4, the motor 29B is disposed on one surface of the base body 40B together with the solenoid valve 15 and the solenoid valve 16. One surface of the base body 40B is a housing / motor mounting surface that serves as both a housing mounting surface and a motor mounting surface. The motor 29B is attached to the base body 40B by attachment bolts 29a. Since the control board 99 which is the main body of the control unit 30B is collectively stored in the housing (FIG. 2, reference numeral 36), the control board 99 is disposed close to the motor 29B above the motor 29B. .

  The motor terminal 29b provided on the upper surface of the motor 29B needs to be electrically connected to the upper control board 99, and the coil connection of the electromagnetic coil 33 of the electromagnetic valves 15 and 16 disposed on the side of the motor 29B. It is necessary to electrically connect the coil side press-fit terminal 128 as a terminal and the control board 99.

  A coil-side press-fit terminal 128 is connected to a through hole 99 b provided in the control board 99. The coil-side press-fit terminal 128 has a spring-like O-shaped portion 128a and can be electrically connected only by being inserted into the through hole 99b.

At the same time, a motor-side press-fit terminal 125 as a motor connection terminal is connected to a through hole 99 a provided in the control board 99.
The motor-side press-fit terminal 125 has a spring-like O-shaped portion 125a, and can be electrically connected only by being inserted into the through hole 99a. The base part of the motor-side press-fit terminal 125 is a male terminal part 125b. Since the base part of the motor-side press-fit terminal 125 is the male terminal part 125b and the motor terminal 29b is also a male terminal, the female-female terminal 127 is required.

As shown in FIG. 5A, the female-female terminal 127 includes a bent portion 127a bent in a U-shape and a male terminal of the motor-side press-fit terminal 125 formed integrally with one end of the bent portion 127a. One female terminal 127b to which the portion 125b is fitted, and the other female terminal 127c that is integrally formed with the other end of the bent portion 127a and to which the motor terminal 29b is fitted.
Therefore, the motor 29 </ b> B is connected to the control board 99 by the motor-side press-fit terminal 125 and the female-female terminal 127.

A female-female terminal 127 including a bent portion 127a and having a U-shape is employed, and the female terminal 127b is disposed on the side of the motor 29B. Therefore, the motor-side press-fit terminal 125 can be lowered, and FIG. In b), the tip height of the motor-side press-fit terminal 125 and the tip height of the coil-side press-fit terminal 128 can be made the same.
Further, in FIG. 2, when the electromagnetic coil, the motor, and the control board are accommodated in the housing 36, it is possible to suppress the generation of a useless space (S) in the height direction.

Since the height is the same, in FIG. 4, the motor-side press-fit terminal 125 and the coil-side press-fit terminal 128 can be easily fitted on the same flat control board 99, and the electromagnetic coil 33 and the motor 29B. Can be controlled by the same control board 99, and an increase in the number of control boards 99 more than necessary can be suppressed.
Since the motor-side press-fit terminal 125 can be lowered, the distance between the motor 29B and the control board 99 is shortened, and the vehicle brake fluid pressure control device 10B can be downsized.

In the embodiment of the present invention, a press-fit terminal is used as the connection terminal, but the present invention is not limited to the press-fit terminal, and other connection terminals may be used.
The vehicle brake hydraulic pressure control device of the present invention is suitable for a motorcycle, but can also be applied to a tricycle and can be applied to a general vehicle.
