The present invention relates to a mounting bolt for fixing a speed sensor for an automobile, and can be easily assembled by changing the shape of the mounting bolt, to provide a mounting bolt that can prevent loosening and recompatibility, and prevent corrosion It is to.

In general, the anti-lock brake system (ABS) system required to prevent the lock of the wheel during braking is composed of a wheel speed sensor (WSS), an ECU, a modulator, and an ABS relay. In order to detect the rotational speed of the tires, four tires are mainly equipped with a wheel speed sensor (WSS), which is an electronic pickup rotation sensor.

The wheel speed sensor WSS is bolted to the wheel bearing using a mounting bolt.

At this time, the mounting bolt should be able to maintain a constant assembly force between the wheel bearing and the wheel speed sensor to prevent the wheel speed sensor from being separated from the wheel bearing during driving.

Therefore, the mount bolt was formed by convex portions and concave grooves formed in a spiral shape on the surface thereof to rotate and assemble the female screw portions provided in the wheel bearings.

However, the mount bolt for attaching such a conventional wheel speed sensor to the wheel bearing may be damaged if the wheel bearing part is too large, and the wheel speed sensor may be damaged due to damage to the wheel bearing part, and is separate from the automated manufacturing process of the wheel bearing. In the process of assembling, rotating and assembling, as well as affect the assembly time (cycle time), there was a problem that corrosion occurs due to assembly with the wheel bearing.

The present invention has been made to solve the above problems, to change the shape of the mounting bolt, to facilitate the assembly, to prevent the loosening and re-compatibility function, to provide a mounting bolt that can prevent corrosion The purpose.

In order to achieve the above object, the present invention provides a wheel bearing including a flange having a threaded groove formed on the inner circumferential surface, a speed sensor having a sensor mount supported on the flange of the wheel bearing, and the wheel bearing and the speed. In the vehicle mounting bolt comprising a mounting bolt provided to engage the sensor, the mounting bolt is pressed into the fixing groove of the flange by a spring portion formed in the reverse direction of the assembly direction, thereby coupling the speed sensor to the wheel bearing Characterized in that.

The mountain bolt includes a head portion and a body portion formed with the spring portion, and the spring portions formed on the body portion are formed to be spaced apart from each other.

The spacing distance of the spring portion is characterized in that formed at a position corresponding to the pitch of the thread portion.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an exploded perspective view schematically showing an assembly of an automobile speed sensor according to the present invention, FIG. 2 is a cross-sectional view schematically showing an assembly of an automobile speed sensor according to the present invention, and FIG. 3 is an automobile according to the present invention. Perspective and sectional drawing of the mount bolt for.

1 and 2 include a wheel bearing 20 and a mounting bolt 30 for fixing the speed sensor 10 for a vehicle according to the present invention.

The wheel bearing 20 is provided with a flange 21 for fixing the speed sensor 10, and the speed sensor 10 is provided with a sensor mount 11 to be fixed to and supported by the flange 21.

The flange 21 of the wheel bearing 20 has a through hole 21b for penetrating the speed sensor 10 and a fixing groove 21a for fixing and supporting the speed sensor 10 at predetermined intervals. Is formed.

The threaded portion 22 is formed on the inner circumferential surface of the fixing groove 21a formed to a predetermined depth, and is fastened by the mount bolt 30 to be described later.

The speed sensor 10 is attached to the flange 21 of the wheel bearing 20 and is fixed by a double sensor mount 11 formed so as not to be loosened or broken by external vibration.

The sensor mount 11 of the speed sensor 10 includes a lower sensor mount 11b in direct contact with the flange 21 and an upper sensor mount 11a on which the mounting bolt 30 is assembled, and the upper sensor mount ( A rubber dustproof member 40 is provided between 11a) and the lower sensor mount 11b to absorb shocks due to vibration.

In the sensor mount 11 of the speed sensor 20, a fixing hole 12 having a position and a size corresponding to the fixing groove 21 a of the flange 21 is formed, and the speed sensor 10 is attached to the wheel bearing 20. Mount bolt 30 for fixing is inserted and fixed.

At this time, the mount bolt 30 passes through the flange 21 fixing groove 21a and the fixing hole 11a of the sensor mount 11 to fix the speed sensor 10.

As shown in FIG. 3, the mount bolt 30 according to the present invention includes a hexagonal head portion 31 and a cylindrical body portion 32 in which a spring portion 50 is formed.

The head 31 of the mount bolt 30 is formed in a hexagon, it is useful in the rotation assembly of the mount bolt 30.

The spring portion 50 formed in the body portion 32 of the mount bolt 30 is formed in the reverse direction of the mounting bolt 30 assembly direction and has an inclined surface 51 formed to be inclined toward the head 31.

Here, the spring portion 50 is formed to be opposed to the one side and the other side at 180 degrees at the same position of the body portion 32, a plurality of spring portion 50 is formed spaced apart from each other.

The spring portion 50 has a predetermined elasticity to facilitate insertion when the mount bolt 30 is inserted.

The inclined surface 51 of the spring portion 50 is an inclined surface formed in the assembling direction when the mounting bolt 30 is inserted into the fixing hole 11a of the sensor mount 11 and the fixing groove 21a of the flange 21. It can be inserted smoothly using (51).

The spring portion 50 of the mound bolt 30 is integrally molded in the reverse direction of the assembly direction when the mount bolt 30 is ejected, and is easily assembled by press-fitting the head 31 of the mount bolt 30.

Due to the spring portion 50 formed opposite to the mounting direction of the mount bolt 30, the mounting bolt 30 can be prevented from loosening during external vibration, and the mount bolt 30 is mounted due to the spring portion 50 designed to cross each other at an angle of 90 degrees. The shaking caused between the bolt 30 and the threaded portion 22 formed in the fixing groove 21a of the flange 21 was prevented.

In addition, the spring portion 50 formed spaced apart from the body portion 32 of the mounting bolt 30 maintains the length (pitch, P) of the general bolt, that is, the thread portion of the fixing groove (21a) When the spring portion 50 is formed at a position corresponding to the pitch of 22 to loosen the mount bolt 30, it is possible to prevent the mount bolt 30 from being damaged.

In addition, a portion exposed to the outside of the mount bolt 30 is formed of plastic, and there is no need for a separate anti-corrosion coating process.

As described above, the present invention having the configuration as described above has the effect of changing the shape of the mounting bolt for fixing the speed sensor for automobiles, making the mounting of the mounting bolt easy, and preventing the loosening of the speed sensor due to vibration. There is.

In addition, the material of the mounting bolt is made of plastic and spring steel, it is possible to achieve the effect of preventing corrosion.
