Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to adjusting and mounting a sensor for wheel speed detection in an anti-skid brake system.

Even after completing the vehicle, it was necessary to adjust the gap between the teeth of a gear that is attached to the hub and rotates together with the wheel to detect the wheel speed, and the sensor that generates pulses due to the rotation of the gear. In the past, since the sensor was installed in the dust cover behind the disk rotor, it was necessary to remove the wheel or disk rotor in front of the sensor to adjust the sensor's position. In addition, sometimes it was necessary to remove the hub, wheel speed detection gears, and sensors in order to make adjustments.

Therefore, in order to eliminate the inconvenience of the adjustment work, the present invention has been developed to connect the gauge used for adjustment to the tooth surface of the speed detection gear without removing anything from the car body, even if the car is already completed. There is a small hole in the dust cover that allows adjustment by placing it in the gap between the sensors.

To explain the above in terms of aspects, as shown in FIGS. 1 and 2, a hub 3 is rotatably attached to a knuckle 1 via a bearing 2, and a wheel speed detection gear 5 is attached to the hub by a pin 4. A disk rotor 6 and a tire mounting wheel are fixed to the outside, and a dust cover 7 is attached to the knuckle 1 on the back surface of the disk rotor 6. Conventionally, the wheel speed detection sensor 8 was housed inside the dust cover 7, but in the present invention, a fan-shaped hole 9 is made in the sensor installation part of the dust cover so that the mounting position of the sensor 8 can be adjusted. It is something to do.

Therefore, when assembling the car body, temporarily tighten it.
This is used to adjust the position of the sensor. In creating a gauge 10 with a thickness that predetermines the distance between the gear tooth surface and the sensor, as shown in FIG. Pass it through the small hole 9 made in the dust cover 7 from inside the vehicle body, such as the cover 7, and insert it to the side of the sensor and hit it against the tooth surface of the gear 5. Next, as shown in FIG. 4, the gear 5 is rotated or the gauge 10 is slid so that the gauge 10 comes between the gear and the sensor, and the sensor 8 is brought into contact with the gauge 10 and fixed. On top of that, the fifth
As shown in the figure, the gap between the tooth surface of the gear and the sensor is adjusted to the thickness of the gauge by returning the gauge to its original position and then pulling it out.

As a result of the above, in the past, the position of the sensor that detects the wheel speed was blocked from outside the car body by the brake rotor, etc., and the sensor itself was in the way and could not be adjusted from the inside. After assembly, the brake rotor can be easily readjusted without removing the brake rotor, etc., even when the vehicle is completed, and the work efficiency can be improved with a simple structure.

Claims (1)

[Scope of utility model registration request] The gap between the surface of the wheel speed detection gear 5, which is fixed to the inside of the hub 3 by a pin 4 and rotates together with the wheel, and the wheel speed detection sensor 8 is adjusted by adjusting the position of the sensor. The wheel speed of the anti-skid brake system has a small fan-shaped hole 9 into which a gauge 10 for adjustment can be inserted and removed, formed at the sensor installation position of the dust cover 7 that covers the back side of the disc rotor 6 attached to the hub 3.
