Description

The invention relates to a wheel guide rail according to the preamble of claim 1, a vehicle treatment system according to the preamble of claim 22 and a method for cleaning the wheels of a vehicle according to the preamble of claim 26.

In gantry washing systems in which the vehicle to be washed is retracted by the driver in the gantry washing and parked there for washing with a traversable in the entrance and longitudinal washing portal, wheel guide rails are known. These serve to position the vehicle transversely to the longitudinal direction as centrally as possible between the washing portal and the treatment devices arranged thereon, for example rotating side washing brushes or high-pressure nozzles.

So revealed the US 6 561 202 B1 a vehicle washing system with a driving range for the vehicle to be washed, which is provided on the two outer sides of the vehicle with Radleitschienen. In the retraction area, the wheel guide rails are widened outwards in a V-shape. The driver drives his vehicle on sight between the wheel guide rails in the washing position in the vehicle washing system. In order to prevent the driver from driving too far to the right or left, as a result of which he touches on the wheel guides only partially, visible, largely vertically upwardly directed, guide posts are provided on the wheel guide rails even during entry. The risk that the driver anfährt the wheel guide, thereby significantly reduced. In order to prevent the treatment devices from touching the guide posts during washing, the guide posts are folded longitudinally against the wheel guide rails.

The JP H11-105 677 A discloses a gantry car wash with a movable on rails in the retractable and longitudinal direction of the vehicle and the gantry car wash washing portal. In order to optimally position the vehicle in the washing area in the gantry washing system, a pair of wheel rails is fastened to guide the front and rear wheels of a vehicle side. The wheel guide rail pair has a V-shaped retraction area and then narrows to a narrow lane for the front and rear wheels. The vehicle then moves through the pair of wheel guide rails into the optimum washing position. When extending the vehicle forward but there is the Radleitschienenpaar in the way, because the driver does not want to go straight to the front end of Radleitschienenpaars, but possibly also the side. It happens that the driver with the guided in the Radleitschienenpaar wheels of a vehicle side drives over the Radleitschienen while tires, rims or Radleitschienen be damaged. Therefore, the Radleitschienenpaar is sunk only during the extension after the end of the washing process in the ground. This has the disadvantage that it is not structurally possible or undesirable in many vehicle washing systems to excavate pits in the ground in which the wheel guide rails can be sunk with their drive arrangement.

The US 4,981,151 discloses a conveyor belt for a vehicle washing system, wherein the side of the conveyor belt two Radleitschienen are constantly pressed towards each other. As a result, tires of different sizes should always be centered on the conveyor belt.

The US 2014/0 170 324 A1 discloses a vehicle washing system with a laterally on the vehicle wheels to be moved sprayer.

The US 5,730,061 A discloses a conveyor belt for a vehicle washing system, in which two Radleitschienen are fixedly arranged laterally of the conveyor belt.

The US Pat. No. 3,596,241 discloses a gantry washing system with fixed Radleitschienen arranged laterally of the washing area.

The DE 20 2008 009 959 U1 discloses a fixed Radleitschiene for a vehicle washing system, with a in the installed state of the washing machine floor upwardly facing and extending along the direction of travel of the vehicle to be treated machine edge, which is designed so that it is inclined upwards to the driving range.

In recent years, the tires of the wheels have become increasingly lower in motor vehicles. This is especially the case with large vehicles such as off-road vehicles or SUVs, which often have low profile tires with extremely low rubber tires and large rims. These vehicles are also often wide and have a large gauge, which means that they occupy almost all the available width between the arranged on both sides of the washing and retraction area Radleitschienen in many vehicle washing systems, especially older car washes. Often the tires are then very close to the wheel guide rails or even touching them.

In vehicles with a small gauge this problem does not exist in principle, however, the drivers are often unable to position the vehicle centrally between the Radleitschienen, but steer very close to one of the two Radleitschienen. Even then are the Vehicle wheels very close to the wheel tracks. Especially with small vehicles, the rubber tires are often relatively low.

So that the drivers of vehicles with very large wheels feel the start of a wheel guide rail when entering the wash area, the wheel guide rails must be at least 60 mm high. If the wheel guide rails are lower, the drivers of such vehicles often do not notice that they touch or even drive over a wheel guide rail.

This minimum height of the Radleitschienen leads with the low rubber tires that when positioned very close to the Radleitschienen wheels, the Radleitschienen cover the lower parts of the vehicle rims and the tires, so that these areas can not be cleaned by the usual rim washing. Especially in conventional wheel wash brushes, which are delivered from the side obliquely in the axial direction of the vehicle wheels on this, then the lower portions of the rim and the tire can not be cleaned, leaving behind the back of the wheel rim unsightly, asymmetric soiling.

The object of the present invention is therefore to overcome the abovementioned disadvantages and to provide a wheel guide rail, a vehicle washing system and a method for cleaning vehicle wheels, which enable complete cleaning of the vehicle wheels and in particular of the vehicle wheels.

11 a side view of a vehicle washing system according to the invention.

1 shows a vehicle washing system according to the invention in the form of a gantry washing system 1 with a washing portal 2 , The washing portal 2 has two substantially vertical portal columns 3 . 3 ' on, passing through a portal traverse 4 are connected. At the laundry portal 2 are vertical side washing brushes 5 . 5 ' and a horizontal roof brush 6 arranged. At the bottom of the portal columns 3 . 3 ' are rim wash brushes 7 . 7 ' arranged, which via delivery devices 8th . 8th' from the in 1 shown retracted position to a longitudinal center axis M of the gantry washing system 1 can be extended.

How good in 2 recognizable, the washing portal points 2 castors 9 . 9 ' on, on the ground 10 the gantry washing system 1 mounted rails 11 . 11 ' to run. The washing portal 2 can thus by a drive, not shown in detail in a longitudinal direction L of the gantry washing system 1 be moved back and forth.

The above-described formation of a gantry washing system 1 is known per se and therefore does not require a detailed description.

Next are on the ground 10 between the rails 11 . 11 ' Radleitschienen according to the invention 12 . 12 ' mounted, which a washing area W for a vehicle to be washed 13 limit laterally. So that the washing area W is as wide as possible, are the Radleitschienen 12 . 12 ' as close as possible to the rails 11 . 11 ' arranged, but without the procedure of the washing portal 2 to hinder. The wheel guide rails 12 . 12 ' serve for the lateral guidance of in 1 shown front wheels 14 . 14 ' of the vehicle 13 when driving into the washing position, possibly also the non-visible rear wheels. As the wheel rails 12 . 12 ' are formed largely identical, is hereinafter in the 1 right wheel guide rail 12 described. The statements apply accordingly also for the mirror-image arranged left wheel guide rail 12 ' ,

As in particular from 3 to 5 shows, the wheel points 14 in a known manner one on a wheel rim 15 mounted, filled with compressed air rubber tires 16 on. Here is the rubber tire 16 lower than the wheel guide rail 12 ,

According to the invention is in 3 wheel guide rail shown in detail 12 between a drawn with solid lines stop position for the wheel 14 and a dashed line wheel wash position for washing the vehicle 13 , in particular for washing the wheel 14 with the rim washing brush 7 , movable back and forth.

For this purpose, the wheel guide 12 by means of a longitudinal L parallel to the rail 11 extending bottom plate 17 on the ground 10 attached. At her the washing area W and thus the wheel 13 facing end of the bottom plate 17 is about a first pivot 18 a stop flank 19 about a longitudinal axis L extending first rotational axis D1 arranged pivotally. The stop flank 19 is advantageously made of a stable, material, such as a 5 to 15 millimeters thick elongated steel sheet.

Advantageously, the hinge 18 be designed similar to a piano hinge massive construction. For this purpose, a first propeller shaft passes 20 by in the longitudinal direction L alternating hinge eyelets 21 the bottom plate 17 and in 3 not shown corresponding hinge eyes the stop edge 19 , Around the stop flank 19 between the in 3 To move shown stop position and wheel wash position back and forth is the propeller shaft 20 rotatable in the hinge eyes 21 the bottom plate 17 stored. On the other hand, the PTO shaft 20 non-rotatably with the hinge eyelets of the stop flank 19 and thus rotatably with the stop edge 19 connected. In addition, one or both ends of the propeller shaft 20 connected to a not shown rotary drive, the first PTO shaft 20 and thus the stop flank 19 by an angle of rotation α between the stop position and the wheel washing position can move back and forth, as indicated by the arrow 22 indicated.

Instead of the rotatably driven propeller shaft 20 could be the stop flank 19 also via one or more over in the longitudinal direction L at the Radleitschiene 12 distributed arranged lifting cylinder with joint drive between the stop position and the wheel washing position and are moved.

After retracting and positioning the vehicle 13 becomes the stop flank 19 brought from the stop position in the folded-down wheel washing position. In some gantry washing systems, the driver then gets out of the vehicle 13 off and leaves for washing the vehicle 13 the gantry washing system 1 , In order to prevent the driver in this case from the folded-down wheel guide rail 12 gets stuck and stumbles, the wheel guide 12 be advantageously designed so that they in the wheel washing position as possible a plane, non-dangerous walkway tread 23 formed.

For this purpose, it is provided that at the stop edge 19 by means of a second rotary joint 24 a footboard 25 is arranged rotatably about a second axis of rotation D2 extending parallel to the axis of rotation D1. Here is the hinge 24 similar to a massive piano band with a second propeller shaft 27 , which by further in the longitudinal direction L alternate hinge eyes 26 from stop flank 19 and tread plate 25 runs, trained.

Next is at the tread plate 25 on their long-distance other side 28 over a third pivot 29 an elongated support plate 30 about a parallel to the rotation axis D2 extending third axis of rotation D3 rotatably arranged. Here is the hinge 29 similar to a massive piano band with a third propeller shaft 31 , which by further in the longitudinal direction L alternate hinge eyes 32 from tread plate 25 and support plate 30 runs, trained.

Here is the third pivot 29 so on the tread plate 25 and the support plate 30 arranged that at the in 3 shown stop position a hinge-side end face 33 the support plate 30 at the bottom of the tread plate 25 , which over the hinge eyelets 32 protrudes, strikes. As a result, the opening angle between tread plate 25 and support plate 30 be limited to 90 °. This could also be achieved in an alternative embodiment in that the hinge-side end face 33 the support plate 30 above the hinged eyelets 32 extends and the hinge-side end face of the tread plate 25 on the left flat side of the support plate 30 strikes. In the above manner, a means for limiting the angle between treadboard 25 and support plate 30 provided.

By this limitation of the opening angle is one of the hinge-side end face 33 opposite hinged end face 34 the support plate 30 then essentially perpendicular to the bottom plate 17 on.

Will the stop edge 19 the wheel guide rail 12 then from the in 3 with solid lines drawn stop position by means of the first propeller shaft 20 to the ground 10 folded down in the dashed wheel wash position, so the tread plate moves 25 corresponding to the right, causing the support plate 30 tilts to the right, as if by the arrow 35 indicated. The support plate 30 then comes under the footboard 25 flat on the bottom plate 17 to lie. Here are the thickness of the tread plate 25 , the support plate 30 and the diameter of the swivel joint 27 so that they are in total in the wheel washing position as high as those through the first pivot 18 held stop edge 19 , here as high as the diameter of the first swivel joint 18 ,

By then flush with each other tops of the stop edge 19 and tread plate 25 becomes the wide, common tread 23 educated. The tread 23 is thus easily accessible and provides for the driver of the vehicle 13 not an obstacle when looking for the positioning of the vehicle 13 get out and leave the wash area W.

Preference may be given to the first rotary joint 18 and the second pivot 24 same diameter and thus have the same height, so that the tread 23 parallel to the bottom plate 17 and thus also to the ground 10 runs.

By limiting the opening angle between tread plate 25 and support plate 30 is used both when folding up and when folding down the wheel guide rail 12 prevents the support plate 30 contrary to the direction of rotation 35 about the in 3 shown 90 ° position swinging out to the right.

4 showed an alternative embodiment of a Radleitschiene invention 36 which between the in 4 drawn with solid lines top stop position and drawn with solid lines lower wheel washing position can be moved back and forth.

This is on the one hand in the ground 10 a the dimensions of the wheel guide 36 corresponding U- or trough-shaped depression 37 intended.

On the other hand, the wheel guide rail 36 an inverted U- or trough-shaped cross-section, which is manufacturing technology favorable. It forms an in 4 vertically extending stop leg 38 the stop for starting with the wheel 14 of the vehicle 13 as shown in the raised stop position. An in 4 horizontally extending connecting leg 39 forms a plan with the ground in the lowered wheel washing position 10 running tread 40 , Thus, the driver can get out of the vehicle 13 get out and run out of the washing area W safely.

As lifting drive for the wheel guide rail 36 may preferably be in the recess 37 arranged pneumatically or hydraulically operated lifting cylinder 41 with one on the connecting leg 39 arranged retractable and retractable piston 42 be used. The training and control of such lifting cylinder 41 is basically known and needs no further explanation. Instead of the illustrated linear actuator but other suitable drives can be used with which lifting and lowering the Radleitschiene 36 is possible. Also, the lifting drive in other ways with the Radleitschiene 36 get connected.

In 5 is another Radleitschiene invention 43 shown which is similar to the one in 3 shown wheel guide rail 12 is trained. Corresponding parts therefore bear the same reference numerals with an apostrophe.

In the 5 shown embodiment of the wheel guide rail 43 again has a bottom plate 17 ' on, at the Radnahen longitudinal side via a first pivot 18 ' a stop flank 19 ' is rotatably arranged. At the stop flank 19 ' is in turn via a second pivot 24 ' a footboard 25 ' rotatably articulated. This training corresponds to the in 3 described embodiment with slightly different dimensions.

Unlike the in 3 shown wheel guide rail 12 has the wheel guide rail 43 but no support plate 30 on. Instead, there is on the far wheel long side of the bottom plate 17 ' a shelf 44 arranged flat. On the shelf 44 can the free, wheel-remote end of the treadle 25 ' glide along.

Will the wheel guide 43 from the stop position (solid lines in 5 ) in the folded wheel-washing position (dashed lines in 5 ), forms the stop flank 19 ' due to the equal diameter of the first pivot 18 ' and the second pivot 24 ' one parallel to the bottom plate 17 ' running first tread 45 , The tread plate 25 ' forms a slight angle to the shelf 44 inclined second tread surface 46 ,

In an alternative, not shown embodiment, the bottom plate 17 ' preferably be so thick that the folded tread plate 25 ' in the wheel washing position flush and just to the stop edge 19 ' connects, so that in turn forms a common flat tread. Here, the tray can 44 possibly be formed of a plurality of stacked individual sheets.

Alternatively, the diameter of the second rotary joint 24 ' smaller than the diameter of the first swivel joint 18 ' so that the stop flank 19 ' slightly inclined to the shelf 44 is inclined. In an advantageous development while the diameter of the first rotary joint 18 ' and the second pivot 24 ' chosen so that the stop edge 19 ' and the tread plate 25 ' form a common, flat, flush and slightly inclined tread in the wheel washing position.

An in 6 to 9 shown Radleitschiene invention 47 is a modification of the wheel guide rail 43 out 5 Mainly due to the type of drive for folding up the stop flank 19 ' different. Therefore, the differences will be described below, in particular, the same parts will be given the same reference numbers.

Around the stop flank 19 ' and the tread plate 25 ' in the in 6a) To bring shown raised position, there is a in 8th shown in detail swivel plate 48 intended. The swivel plate 48 has a web-shaped stop on its long wheel side remote 49 on, at which the Radferne front side of the tread plate 25 ' strikes. The tread plate 25 ' is in 8th not shown, to the underlying mechanism for raising or lowering the stop edge 19 ' and the tread plate 25 ' to explain better.

To the movement of the swivel plate 48 between the in 6a) and b) to allow positions shown, a lever assembly is provided, which is based on 8th and 9 is explained.

The swivel plate 48 is moveable on several similarly designed storage elements 50 on which stuck on the bottom plate 17 ' are arranged. Possibly. can the storage elements 50 also in one piece with the bottom plate 17 ' be made. The storage elements fulfill the function of the shelf 44 out 5 ,

Between the storage elements 50 are also similarly trained circular sector-shaped lever arms arranged with holes at their ends, which by means of a lever arm 51 to be discribed. Into the holes of the lever arm 51 On the one hand, it engages from the bottom plate 17 ' upwardly projecting hinge pin 52 and on the other hand, one of the swing plate 48 downwardly projecting hinge pin 53 so that the lever arm 51 around the hinge pin 52 respectively. 53 is rotatably mounted. Thus, the pivot plate 48 between the in 6a and b positions shown are moved back and forth.

For defined guidance of the swivel plate 48 are provided in a plurality of identically formed curved guide slots, with an example in the one guide slot 54 one on the bottom plate 17 ' attached guide pin 55 intervenes. The same applies to the unspecified leadership scenes accordingly.

Will the swivel plate 48 now in the longitudinal direction L in the in 6a) and 8th shown position pushed to the right, so the pivot plate moves 48 at the same time as the stop flank 19 ' and thus to the wheel 14 out, causing the stop edge 19 ' is raised. Will the swivel plate 48 then in the longitudinal direction L in the in 6b) shown position pulled to the left, so the pivot plate moves 48 from the wheel 14 away, causing the stop flank 19 ' is lowered due to its own weight.

To the swivel plate 48 In the longitudinal direction L to move back and forth, it is rotatable about a about a longitudinal axis L extending axis of rotation connector 56 with a feed bar 57 a double-acting hydraulic cylinder 58 connected, as in 6 shown. The when moving the feed bar 57 in the longitudinal direction L resulting lateral offset transversely to the longitudinal direction L can be accomplished by the skilled person common means. For example, the feed bar 57 between connector 56 and hydraulic cylinder 58 be rotatable in the manner of a connecting rod about a vertically upwardly extending axis of rotation, or the hydraulic cylinder 58 can be rotatably mounted about a corresponding axis of rotation. Means for compensating for lateral misalignment will be appreciated by those skilled in the art from the knowledge and skill known to them.

To the end positions of the swivel plate 48 to be able to determine is at the feed bar 57 an angled switching flag 59 provided, the front or rear position by means of two inductive proximity switch 60 . 61 can be detected. By polling the proximity switch 60 . 61 can thus be ensured that the Radleitschiene 47 either in the raised stop position or in the lowered wheel washing position.

In the alternative embodiment according to 7 will replace the in 6 shown hydraulic cylinder 58 an electric motor 62 used with reversing gear to the swivel plate 48 to move in the longitudinal direction L. Otherwise, the two versions do not differ. Also there, the lateral offset when moving the feed rod 57 be compensated in the longitudinal direction L with the expert usual means.

Basically, at the in 6 to 9 shown embodiment, the pivotal movement of the pivot plate 48 also only via the lever arms 51 or the leadership scenes 54 However, the use of both funds improves the leadership.

At the in 6 to 9 shown and described above Radleitschiene 47 can also be easily detected, whether a wheel 14 of the vehicle 13 on the raised wheel guide rail 47 stands. Because then on the tread plate 25 ' acting great weight will be the movement between guide pins 55 and leadership scenes 54 so strongly inhibited that the power of the drives 58 respectively. 62 is no longer enough for the swivel plate 48 to withdraw in the longitudinal direction L. Will the drive 58 respectively. 62 then to move the pivot plate 48 and thus lowering the Radleitschiene 47 controlled, reaches the pivot plate 48 but the in 7 left end position after a predetermined period of time, the system control recognizes that a wheel 14 of the vehicle 13 on the wheel guide rail 5 stands. Reaching the end position can via the proximity switch 60 be determined. The washing process is then not started to avoid the vehicle 13 and / or parts of the car wash 1 , in particular the traveling washing portal 2 to damage. Rather, in this case, a signal can be output that the driver of the vehicle 13 signals that the vehicle 13 is not positioned correctly.

Accordingly, it can also be detected when the vehicle 13 before lifting on the wheel guide rail 47 on the wheel guide rail 47 stands up and thus the power of the drives 58 respectively. 62 is not enough for the swivel plate 48 extend in the longitudinal direction.

Instead of or in addition to the above-described detection of the wheel 14 on the wheel guide rail 47 may in this or in the other above or below described Radleitschienen 12 . 36 . 43 . 47 . 63 a sensor can be provided which, based on the weight acting on the wheel guide rail, gets up the wheel 14 recognizes on or at the Radleitschiene and then outputs a corresponding signal to the plant control.

In the 10 shown further alternative embodiment of a Radleitschiene 63 largely corresponds to the wheel guide rail 43 respectively. 47 out 5 respectively. 6 to 9 , Corresponding parts therefore bear the same reference numerals with an apostrophe.

Lifting a toothed tread plate 64 and thus the stop plate 19 ' happens at the wheel guide rail 63 by a displacement of a toothed drive plate 65 in the longitudinal direction L on a shelf 44 ' , The shelf 44 ' is formed by two superimposed and connected sheets and so high that in the in 10 not shown folded wheel washing position the stop edge 19 ' , the treadle 64 as well as the drive plate 65 a plane, flush and parallel to the bottom plate 17 ' form a running surface. Alternatively, all three plates 19 ' . 64 and 65 also have different inclinations.

Here are in the in 10 shown raised position teeth 64a the tread plate 64 and teeth 65a the drive plate 65 in opposite position, so that the tread plate 64 and with it the stop plate 19 ' is held in the raised position. Thus, the stop edge 19 ' Stable even when a tire 16 to the stop edge 19 ' moves.

Around the wheel guide rail 63 and thus the stop plate 19 ' from the in 10 Lowering the upper position shown, the drive plate 65 moved in the longitudinal direction L to the right or left, causing the teeth 64a and 65a be moved against each other. This allows the tooth flanks of the teeth 64a and 65a glide on each other, reducing the tread plate 64 slowly lowered until the teeth 64a respectively. 64b in corresponding interdental spaces 65b respectively. 64b the tread plate 64 or drive plate 65 to come to rest.

To prevent the drive plate from slipping off 65 transverse to the longitudinal direction to prevent, is on the long side remote from the wheel again in the longitudinal direction L extending stop web 49 provided on the the Radferne longitudinal end face of the drive plate 65 strikes and through which it is guided in the longitudinal direction L.

Lifting the footboard 64 done by moving the drive plate 65 in the opposite direction, causing the teeth 64a . 65a comb each other in a conventional manner and thus the tread plate 64 push upwards.

In the in 10 not shown folded wheel-washing position are the teeth 64a the tread plate 64 thus flat on the shelf 44 ' on and form with your teeth 65a the drive plate 65 a largely plane and thus walk-off area .. Ggf. can if the teeth 64a . 65a and the corresponding interdental spaces 64b . 65b in the folded position in the longitudinal direction L are slightly braced against each other and / or have little play, a through the hinges 18 ' and 24 ' caused play of the treadle 64 in the axial direction of the swivel joints 18 ' and 24 ' , Thus, the longitudinal direction L can be reduced or completely prevented. Thus, the risk of tripping when walking the folded Radleitschiene 63 by slipping the tread plate 64 be further reduced in the longitudinal direction L.

In an in 11 shown embodiment, the Radleitschiene 12 . 36 . 43 . 47 or 63 be divided into sections in the longitudinal direction L, in which the stop edge 19 . 19 ' are movable separately from each other. For example, a movable portion V for the front tires 14 ' and a separate movable section H for the rear tires 14 '' be provided. The adjoining "outer" sections F, however, are fixed, so that especially in the retraction and extension areas, where the risk of driving on the Radleitschiene is greater, no movable Radleitschiene must be provided. Also can be inserted advantageously between these sections V and H, a central portion in which the stop edge is immovable again, whereby the stability of the Radleitschiene can be increased in this central part.

To the wheels 14 . 14 ' of the vehicle 13 To clean, it is first retracted in the washing area W, in which case the Radleitschienen 12 . 36 . 43 . 47 or 63 are in the raised stop position. Drives the vehicle 13 too far to the right or left, push the wheels 14 . 14 ' then at the respective stop edge 19 . 19 ' respectively. 38 at. Is the vehicle 13 positioned in the washing area W, before the start of cleaning the wheels 14 . 14 ' the wheel tracks 12 . 36 . 43 . 47 or 63 and in particular the respective stop flanks 19 . 19 ' respectively 38 moved into the wheel washing position, so that the rim washing devices, especially the rim washing brushes 7 . 7 ' not hindered. After cleaning the wheels 14 . 14 ' can the wheel guide rails 12 . 36 . 43 . 47 or 63 then be raised again. This is preferably done after the exit of the vehicle 13 from the washing area or washer hazard area, to prevent the vehicle 13 on the wheel guide rail 12 . 36 . 43 . 47 . 63 ascends.

Preferably, in the different versions, the stop edges 19 . 19 ' , the tread plates 25 . 25 ' . 64 , the tread 40 and the drive plate 65 be formed of a grippy material, such as a checker plate to facilitate running on it and make it safer.
