Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a washing machine for automobile wheels.

[Prior Art] In recent years, the popularity of car wash machines for car bodies has been remarkable, and it can be said that there is no gas station in all parts of the country that does not have a car wash machine. When these car wash machines are used, the body and windshield of a car can be thoroughly cleaned without the need for manual labor, but the wheels fitted to the tires are not sufficiently cleaned.

Therefore, there was a problem in that the wheels had to be washed manually after the car was washed in a car wash.

[Problems to be Solved by the Invention] The present invention has been made in view of the above-mentioned problems in cleaning wheels in car washes, and it is an object of the present invention to efficiently and cleanly clean wheels without requiring any manpower. The purpose is to provide a wheel cleaning machine that can

[Means for solving the problem] The wheel is originally designed aesthetically, and its surface has complex irregularities and grooves running in various directions. For example, the sole wheel cannot be thoroughly cleaned by simply reciprocating or circular motion.

Therefore, the inventors conducted extensive research to make the bristles of the brush move in accordance with the surface shape of the wheel. As a result, they discovered that rotating the brush while making a circular motion around the axis of rotation of the tire wheel is the most effective way to clean the wheel, and have completed the present invention.

The automobile wheel cleaning machine of the present invention includes: a brush rotation mechanism that rotates a brush rotation shaft while making a circular motion; a brush attached to the brush rotation shaft of the brush rotation mechanism;
A cleaning liquid spout installed toward the wheel, a drive device for the brush rotation mechanism, and a brush movement device that horizontally supports the brush rotation mechanism and the drive device and moves it back and forth in the tire wheel axis direction. This is the summary.

[Operation] A wheel washer is placed on the side of the wheel to be cleaned, and the brush rotation mechanism is placed opposite to align the central axis of circular motion of the brush rotation axis with the rotation axis of the tire wheel. Next, detergent is sprayed from the cleaning liquid spout installed in the center of the brush rotation mechanism, and the drive device is activated to rotate the brush 11! When li/'R is rotated, the brush rotation shaft rotates in a circular motion about the rotation axis of the wheel, and the brush attached to the brush rotation shaft rotates.

The brush moving device is then actuated to horizontally move the brush rotation mechanism and drive toward the wheel so that the bristles of the brush come into contact with the wheel. Since the brush rotating shaft moves in a circle around the rotating shaft of the tire wheel by the brush rotating mechanism, the wheel is scrubbed in all directions with the bristles of the brush and cleaned.

Returning again to FIGS. 1 and 2, the brush rotating machine [22
A motor support member 60 is fixed on the support member 24, and a motor 62 is fixed to this motor support member 60. A drive pulley 66 is fitted onto the output shaft 64 of the motor 62 , and a belt 68 is wound around the drive shaft 28 of the brush rotation mechanism 22 and the pulley 30 . Further, an air cylinder 1 is attached to the side surface of the motor support member 60.
The tip of the piston rod 20 of No. 8 is fixed.

The operation of the apparatus of this embodiment having the above configuration will be explained. As shown in FIG. 1, first, a wheel washer is placed on the side of the tire wheel 70 to be cleaned, and the brush 52 is not opposed to the front surface of the wheel 72, and the central axis 42 of the brush rotation mechanism 22 and the tire wheel 70 are Align the rotation axis of the Next, the detergent is fed into the detergent injection hole 56 formed in the central axis of the brush rotation mechanism 22 and sprayed from the detergent injection nozzle 58, and the motor 62

rotates.

On the other hand, since the brush drive gear 34 is fitted onto the drive shaft 28, the rotation of the brush drive gear 34 rotates the brush rotation carrier gear 46 that meshes with the brush drive gear 34.

The brush rotation carrier gear 46 meshes with the brush rotation gear 54, thereby causing the brush rotation gear 54 to rotate, thereby causing the brush rotation shaft 50 to rotate. However, since this brush rotating shaft 50 is pivotally supported by the rotating plate 48, the brush rotating shaft 50 rotates while making a circular motion.

Therefore, the brush 52 attached to the tip of the brush rotating shaft 50 rotates while making a circular motion about the central shaft 42.

Next, when the air cylinder 18 of the brush moving device 10 is actuated to push out the piston rod 20, the motor support member 60 and the brush rotation mechanism support member 24 are pushed forward, so the support rod 16 slides inside the support cylinder 14. do,

In this embodiment, the motor 62 is fixed on the brush rotation mechanism 22, but the motor 62 has a brush rotation mismatch.
It may be fixed next to the Further, although the brush rotating shaft 50 and the brush 52 are shown to be horizontal, this has the advantage that the tire wheel 70 can be washed while being mounted on the car. However, if the brush rotating shaft 50 and the brush 52 are supported vertically, the wheel 72 of the tire wheel 70 that is not mounted on the vehicle can be cleaned.

[Effects of the Invention] As explained above, the automobile wheel cleaning machine of the present invention cleans the wheels with a brush that rotates while making a circular motion around the rotation axis of the tire wheel. Since the bristles of the brush can follow the complex surface shape, it is possible to clean the wheels extremely efficiently and without the need for manual labor. In addition, compared to simple circular motion, the shape of the brush can be made smaller, and since the friction surface is smaller, the torque required for rotation is less, and the motor 3 can be made smaller.Furthermore, since the brush can be moved back and forth by the brush moving device,
The brush spreads due to centrifugal force according to the rotation speed, and by adjusting the forward and backward movement for wheels with different diameters, the entire surface can be cleaned without leaking, and the pressing force of the brush can be changed. It has many excellent effects, such as the ability to
