Description

Wheel cleaning device for vehicles {Wheel a cleansing device for vehicle}

The present invention relates to a washing apparatus for washing wheel wheels of large vehicles such as buses and trucks, and more particularly, to improve cleaning efficiency by allowing brushes to come into close contact with each other regardless of the shape of the front wheels and rear wheels of large vehicles. It relates to a vehicle wheel cleaning device that can increase the reliability of the operation.

In general, the wheel of the vehicle is a rotary body that rotates by the power of the engine while supporting the vehicle body to a predetermined height with respect to the ground, is coupled to the hub installed on the tip of the axle arranged on both sides of the vehicle body, the bolt provided inside Various fasteners, such as, etc. and various structures such as hub (Him) and rim (Rim) and also serves as an exterior material while shielding the exposure to the outside.

Such wheels require frequent wheel cleaning as tires or wheels are easily contaminated by dirt or debris while driving the vehicle, but most people are indifferent to cleaning the wheels, making it difficult to maintain cleanliness.

In particular, in the case of a large commercial vehicle such as a bus, the cleanliness of the vehicle is very important as part of the service to the passengers. Affects the image In addition, even in the case of large vehicles such as trucks, there is a problem that it is difficult to maintain the cleanliness of the vehicle due to the characteristics of frequent driving and aggregates such as gravel, sand.

In order to solve such a problem, a wheel cleaning apparatus having a brush disposed in the vehicle width direction and cleaning the wheel has been proposed.

However, the conventional wheel cleaning device has a problem in that the length of the brush is unsuitable for cleaning the wheel of a large vehicle. That is, when looking at a large vehicle such as a truck or a bus, the front wheels are one by one and the rear wheels are two pairs of structures. As a result, the wheels of the front wheels are provided to protrude to the outside and the wheels of the rear wheels are tires. Since the two are to be inserted into each other, the wheel is provided at the center and a predetermined depth is provided inward so that tires can be disposed on both sides thereof.

Therefore, the brush having a fixed length in the wheel cleaning apparatus according to the prior art can perform a relatively good cleaning for the front wheel, but the shorter the length of the brush for the rear wheel caused a problem that the cleaning state is poor.

In order to solve this problem, a wheel cleaning device including a rail including a compressor, a cylinder, a reduction motor, and a brush and disposed in the width direction of the vehicle has been proposed, but this also has a very complicated structure, which leads to poor serviceability and manufacturing cost. There is a disadvantage that is not economical because it is expensive.

In addition, as the brush rotates, the brush is broken while being entangled in bolts for fixing the wheel, and the brush is frequently damaged, and the broken brush is entangled in the bolt for fixing the wheel.

In order to solve this problem, the applicant has been registered with a wheel cleaning device for a large vehicle to perform the wheel cleaning by spraying the washing water of high pressure through the Republic of Korea Patent No. 10-0740291.

However, the wheel cleaning device for a large vehicle registered by the present applicant is provided with a plurality of nozzles on the rotating head to wash the wheels, so that the structure is simple and economically available and advantageous in terms of maintenance. In order to remove the fixed contaminants, a large amount of washing water has to be sprayed at a high pressure, so there is a problem of low economical efficiency due to the increase in the amount of washing water used.

In addition, as the use of washing water increases, there is a drawback that there is a concern about environmental pollution due to various cleaning chemicals contained in the washing water.Therefore, the wastewater treatment facility for filtering and treating the used washing water has to be expanded and expanded. There was a problem that the burden of facility investment is increased.

In order to solve the above problem, the present applicant has been registered with the improved wheel cleaning device for a vehicle through the Republic of Korea Patent No. 10-0867930, such a vehicle wheel cleaning device is formed vertically to form a vertical to form a skeleton A frame having a frame and a horizontal frame arranged horizontally at a predetermined height of the vertical frame, a link having a predetermined length hingedly suspended from an upper portion of the vertical frame, and for rotating the link back and forth, i.e., in the vehicle width direction. The driving source is rotated at a constant speed by contacting the front and rear cylinders, the lower end of the link, the nozzle for ejecting the wash water to the member which is interlocked with the linkage, and the wheel of the vehicle to receive the driving force by friction. Brush to control and detects the entrance of the vehicle and outputs various control signals It is composed of

The wheel cleaning device for a vehicle registered by the present applicant has a configuration in which a brush having a coil shape is wound around a ring member having an annular shape, thereby allowing elastic flow in the rotational direction during cleaning to prevent damage to the brush while preventing the damage of the large vehicle. It is possible to clean the front and rear wheels.

However, the applicant's registered wheel cleaning device for the vehicle is not only easy to manufacture due to the complicated structure, but also has a disadvantage of poor serviceability. In addition, since the carrier is suspended from the link of the joint structure when the carrier moves forward and backward, it is difficult to accurately match the brush to the wheel of the vehicle.

In order to solve this drawback, the present applicant proposes a wheel cleaning device for a vehicle, which allows a carrier to be accurately positioned on a wheel of a vehicle through a forward and a lift operation by a driving source through Korean Patent Application No. 10-2009-0047914. There is a bar.

However, the wheel cleaning device for a vehicle applied for by the present applicant has a disadvantage of low versatility in washing wheels of various sizes because the size of the brush is determined. For example, a transportation company operating a village bus and a large bus must have a brush for each vehicle wheel size and a brush for each vehicle type. Since it has to be replaced with the right brush, it is not only cumbersome but also has a problem in that manpower and time are consumed.

In addition, the front wheel of the vehicle has a prominent curvature with a gentle curvature as a whole, while the brush performs a relatively good cleaning in line contact with the protruding portion, while the cleaning of the curved surface is difficult. In the case of the rear wheel of the vehicle, the vehicle has a gentle curvature and a predetermined depth, but the brush has a problem in that it is difficult to clean the curved surface part. That is, the brush is composed of brush hair having a constant length (washing), and the cleaning of the curved portion is difficult as the cleaning is performed by rubbing the end of each brush hair to the surface to be cleaned.

The present invention was created to solve the problems of the prior art as described above, an object of the present invention is to allow the brush to vary in diameter according to the shape and size of the wheel, so that the shape and size of the front and rear wheels are different The present invention provides a vehicle wheel washing apparatus capable of stably washing a large vehicle wheel.
