Description

Drive technology for vehicle treatment systems, in particular washing systems

DESCRIPTION

The present disclosure relates to a drive technology for device components, and more particularly

Treatment organs of vehicle treatment plants.

In practice, it is known various

To operate device components of a treatment plant, each with different electric drive motors, the drive motors are usually designed as DC motors or asynchronous motors and adapted to the particular device component to be driven. The known drive motors usually have an inner rotor which acts as an output element and is connected to the device component to be driven, i. it is a matter of

Internal rotor motors.

The previously known drive techniques are not optimally formed. It is therefore the task of the present

Invention to provide an improved drive technology, in particular an improved washer drive, a washer drive motor for use in a washer drive, a treatment plant or

Car wash with a corresponding

Washer drive motor or washer drive, and a treatment member and a vehicle treatment system with a corresponding washer drive motor or washer drive.

The invention solves the problem by the features of the independent claims.

The disclosed drive technology includes a modular concept in which multiple drive motors have a unitary design so that they can drive various device components of the treatment plant

can be used. In addition, a drive motor is proposed with a hollow shaft. By using a hollow shaft, the range of application of the drive motor is massively increased. Through the hollow shaft no one

Media supply for subordinate

Device components or other drive motors are created.

The drive technology provides the preferred use of a synchronous motor, in particular in the form of a

External rotor motor. A synchronous motor can handle many different types of drives

Cover device components. On the one hand, it can be controlled or regulated to a certain speed or a certain torque. In addition, a control or regulation of the rotational position is possible. Thus, the synchronous motor can be used both for purely driving purposes as well as for power- or torque-controlled delivery, as well as for positioning tasks. On

Synchronous motor is thus also suitable for the common driving of a device component with multiple drive motors. The drive technology and / or the modular concept can provide that a plurality of washer drive motors or washer drives can be connected to a system controller via uniform interfaces, wherein the

Plant control for automatic detection and / or

Configuration of a connected drive or its power supply is formed. For a replacement or reconfiguration of a drive motor then no specially trained personnel is no longer necessary. Rather, a plug-and-play concept is achieved.

The disclosed drive technology thus allows a far-reaching reduction in parts costs and facilitates the maintenance and repair of drive motors.

Furthermore, a reduction in energy intake and novel control concepts for the

Device components are achieved.

The present disclosure includes various

The washer drive motor is preferably designed to drive the outer rotor during operation so that it is moved relative to a stationary or relatively slow moving inner rotor / inner stator. In other words, the outer rotor of the

Device component which has a

Drive motor is driven, whose inner rotor has a hollow shaft.

A drive motor with an inner rotor, the one

Hollow shaft has special advantages for the additional media supply or control of a Device component of the treatment plant, which is connected to the drive motor.

Advantage that the number of identical parts significantly increased and thus the manufacturing cost can be reduced. Furthermore, the number of spare parts for a

Treatment plant to be reduced. As a result of

uniform design, a drive motor or a washer drive for various

Device components are used. It may therefore be sufficient to maintain only one or a few drive motors or washer drives as spare parts in the event of a malfunction. The replacement of a defective drive motor or a defective washer drive can be done very quickly and easily due to the uniform design, since no special knowledge of the device components or treatment organs and their drive parameters are necessary.

Treatment method for a vehicle

(Vehicle treatment method), particularly used in a vehicle washing method.

Particular advantages for a vehicle treatment method result from the disclosed embodiment of a

Wheel washer with the movement device (64) and the plate-shaped treatment brush. On

Vehicle treatment method according to the present

Revelation may include the following steps:

• Delivery of a plate-shaped treatment brush

(56) to a vehicle wheel;

• Common operation of a traction drive (68) of the treatment plant and a moving device (64) on which the dish-shaped treatment brush is mounted or guided, such that the

dish-shaped treatment brush in one

Arc movement, so that an outer diameter of the plate-shaped treatment brush (56) in

Is guided substantially tangentially to an outer diameter of the vehicle wheel to be treated (71), and in particular tangentially to a

Outer diameter of a rim (72).

Furthermore, there are special advantages for a

Vehicle treatment method from that in FIG. 2

outlined training a side brush (52) with two or more separately driven brush segments (53, 54), in particular according to the above-explained

Training .

By driving the two or more separately

Brush segments, if necessary, separate and in particular different Waschbesätze or Bürstenbesätze

can have different beneficial effects. The washing mats or brush trimmings can, for example, have the same or different lengths and the same or different trimming materials. Furthermore, the brush segments (52, 53) may each be formed with or without a fluid supply.

End face of the vehicle to at least local lifting off the surface of the vehicle. By the

Takeoff can be insufficient in the transition area, and especially at the left and right rear edges

Treatment results or wash results arise. The lifting can be triggered by the fact that in

Transitional area only a subarea of the

Side washing brush or just a brush segment sufficient or even locally inflated against the

Surface of the vehicle has. By the

Interaction between the rotating brush or the substantially statically arranged surface contour of the vehicle in the transition region may lead to a deflection of the brush. Type and extent of the deflection depend on the formation of the contact zone, the direction of rotation and the rotational speed of the side brush.
