Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mounting structure for an actuator unit for an anti-skid brake system of a vehicle.

[Conventional technology]

Actuator units for appropriately changing the hydraulic pressure of brake oil supplied to the front and rear brakes in a vehicle's anti-skid system generally include those shown in FIGS. 4, 5a, and 5b (for example, 1990
(See page C-63, etc. of the new car manual "Nissan Sunny NX Coupe" published by Nissan Motor Co., Ltd. in January 2017).

In this device, the actuator unit 1 connects the cylindrical motor part 1b of the actuator unit 1 to a rectangular parallelepiped pump in a space S formed between a dash panel 8 and a strut housing 9 located in front of the dash panel 8. It is arranged toward the outer side of the vehicle than the portion 1a. The actuator unit 1 is connected to the front and rear brake cylinders 4 and 6 of the vehicle through pipes 5 and 7, and the dash panel 8 near the strut housing 9 on the opposite side of the actuator unit 1 through the pipe 3.
It is connected to the master cylinder 2b of the booster 2 disposed above. This booster 2 is composed of a booster main body 2a and a master cylinder 2b, with the master cylinder 2b facing toward the front of the vehicle. In addition, 10a in the figure
10b indicates a bracket for attaching the actuator unit 1 to the vehicle body, and 10b indicates a battery.

[Problem to be solved by the invention]

In recent years, as vehicle production becomes more efficient, the parts and components installed in vehicles have become more efficient.
Equipment and various production facilities are being shared, and it is hoped that the installed parts, equipment, and layout of each part can be shared between right-hand drive cars for domestic use and left-hand drive cars for export.

However, in the above-described mounting structure for the actuator unit 1, since the mounting position of the booster 2 is different depending on the right-hand drive vehicle and the left-hand drive vehicle, the position of the space S is necessarily different.

Therefore, the mounting position of actuator unit 1 is also different.
There was a problem in that the piping 5.7 and the bracket 10a could not be shared.

In addition, in order to solve this problem, if the mounting position of the actuator unit 1 is fixed regardless of whether the vehicle is a right-hand drive vehicle or a left-hand drive vehicle, the actuator unit 1 can be installed in either a right-hand drive vehicle or a left-hand drive vehicle. A problem arises in that the booster 2 interferes with the booster 2.

Therefore, the present invention enables piping and brackets to be shared between right-hand drive cars and left-hand drive cars, and when installing the actuator unit, the actuator unit and booster can be used in both right-hand drive cars and left-hand drive cars. An object of the present invention is to provide a mounting structure for an actuator unit for an anti-skid brake system that does not interfere with the actuator unit.

[Means to solve the problem]

As a means for solving the above-mentioned problems, the present invention provides an actuator unit that includes an approximately rectangular parallelepiped pump section and an approximately cylindrical motor section, and is located behind a battery disposed in front of a strut housing. and a master cylinder of a booster disposed behind the actuator unit is arranged in a vertical position. be.

[Effect]

By taking such measures, piping and brackets can be shared in both right-hand drive vehicles and left-hand drive vehicles when installing the actuator unit, thereby reducing man-hours and costs.

In addition, the actuator unit is placed behind the battery, which is placed in front of the strut housing, and at a position below the height of the battery.
Damage to the actuator unit due to touching from above can be prevented.

Furthermore, when installing the actuator unit, the motor part of the actuator unit and the master cylinder of the booster are arranged in vertical positions, so the actuator unit can be installed in both right-hand drive and left-hand drive vehicles. There is no interference between the actuator unit and the booster, and the length in the front and rear direction of the area where the actuator unit and booster exist can be shortened.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

First, an embodiment in which the present invention is applied to a left-hand drive vehicle will be described with reference to FIGS. 1, 2, and 3a.

The actuator unit 11 has a rectangular parallelepiped pump section 1.
1a and a cylindrical motor part 11b integrally fixed to the rear surface of the pump part 11a, and is arranged in front of a strut housing 13 that supports a front wheel suspension member (not shown) formed in the hood ridge 12. The battery 14 is located at the rear of the battery 14. The battery 14 is installed on a front side member 15 that is disposed below the hood ridge 12 and extends in the longitudinal direction of the vehicle via a bracket 16 having a hat-shaped cross section, and one end of the actuator unit 11 is fixed to the side surface of the front side member 15. The other end is placed on the front side member 15 via a bracket 17 fixed on the front side member 15 and a bracket 18 fixed on the bracket 17, and at a position below the height H of the battery 14. It is located.

Dash panel 1 behind actuator unit 11
A booster 20 consisting of a booster main body 2Da and a master cylinder 20b is attached to the booster 9.

Here, the actuator unit 11 is arranged such that the center line L of the motor section 11b of the actuator unit 11 is located below and biased toward the outside of the vehicle with respect to the center line L20 of the master cylinder 20b of the booster 20. ing.

The actuator unit 11 includes the actuator unit 11 and front and rear wheel brake cylinders (
(not shown) connects the brake tube 21.21.22.
22 is routed, and brake tubes 23 and 23 connecting the master cylinder 20b of the booster 20 of the actuator unit 11 are also routed. In addition, 2 in the figure
4 indicates a radiator.

Next, referring to FIG. 3b, an explanation will be given of an embodiment in which the present invention is applied to a right-hand drive vehicle.
The only difference is that 0 is attached to the dash panel 19 on the side opposite to the side where the battery 14 is disposed with respect to the center of the vehicle, and the other configurations are the same as the embodiment shown in FIG. 3a.

In the actuator unit mounting structure configured as described above, since the actuator unit 11 is fixed even in right-hand drive vehicles and left-hand drive vehicles, the brake tubes 21, 21, 22, 22, 23, 23 and brackets 17. 18 can be shared, reducing man-hours and costs.

In addition, since the actuator unit 11 is arranged behind the battery 14 arranged in front of the strut housing 13 and at a position below the height of the battery 14, the actuator unit 11 can be damaged by being touched from above. can be prevented.

Furthermore, since the motor section 11b of the actuator unit 11 and the master cylinder 20b of the booster 20 are arranged in vertical positions, the actuator unit and the booster can be connected to each other in both right-hand drive and left-hand drive vehicles. The devices do not interfere, and the length in the front-rear direction of the portion where the actuator unit 11 and booster 2Q exist can be shortened.

〔Effect of the invention〕

As described above, according to the present invention, piping and brackets can be shared in both right-hand drive vehicles and left-hand drive vehicles when arranging the actuator unit, thereby reducing man-hours and costs.

Furthermore, since the actuator unit is arranged behind the battery arranged in front of the strut housing and at a position below the height of the battery, damage to the actuator unit due to handling from above can be prevented.

Furthermore, when installing the actuator unit, the motor part of the actuator unit and the master cylinder of the booster are arranged in vertical positions, so the actuator unit can be installed in both right-hand drive and left-hand drive vehicles. There is no interference between the actuator unit and the booster, and the length in the front-rear direction of the area where the actuator unit and booster exist can be shortened.
