Description

TECHNICAL FIELD OF THE INVENTION

The invention relates to a multi-part in the wheel circumferential direction truck fender with a to be fixed to a truck frame, front in the direction of travel first plastic molded body to be fastened to the truck frame, in the direction of travel second plastic molded body and one on the first and the second Plastic moldings releasably fastened, in the direction of travel middle third plastic moldings. More particularly, the present invention relates to a truck fender having the features of the preamble of independent claim 1. Furthermore, the present invention relates to a truck having a pair of such truck fenders.

The multi-part construction of truck fenders from a front, a rear and a middle plastic moldings allows to produce the plastic moldings in smaller injection molds than the plastic moldings for a one-piece truck fender. In addition, the front and rear plastic moldings can not only be used as parts of a truck mudguard for a single wheel, but also for a double wheel of a double axle, then in conjunction with a longer central plastic molded body. In particular, however, multi-part truck fenders are used to have the ability to remove the third plastic molded body, d. H. if necessary for space reasons, d. H. If, for example, a load carried by the respective truck reaches so close to the wheel enclosed by the truck fender that there is no space left for the middle plastic molding. In the reverse direction, in a truck normally replacing a semitrailer or superstructure with the middle plastic moldings of its truck fenders, this medium plastic molded article can be supplemented when the truck is driven without the semitrailer or superstructure.

STATE OF THE ART

The DE 10 2011 050 258 A1 discloses an elastic strap of an elastomeric material having at least one protruding from its underside securing element and an upward directional change, which lies in the tensioning direction in front of the securing element. This elastic strap serves to secure a central portion of a three-piece truck fender at its front and rear portions when the transition between the front and rear portions of the truck fender is not made by a semi-trailer pulled by the truck. In this application, a total of four tension straps are used, two each for securing the middle part at the front and the rear of the truck fender. The change in direction of the known tension band can be quickly visually recognize whether it is properly hooked with his fuse element or not. The provision of a total of four straps for securing the middle part of a three-piece truck mudguard means a considerable effort, especially since the function of the straps at different temperatures and environmental conditions durably sicherstellender elastomer material is relatively expensive.

From the WO 2007/118563 A1 is a fender for motor vehicles, especially for mobile concrete pumps known. The mudguard has a dirt catcher that partially overlaps the running surfaces of wheels of the mobile work machine and fastening means for fixing the mud flap to a chassis-fixed point of the work machine. The fender is designed as a self-supporting hollow chamber component made of plastic, which has a strainer portion and an integrally connected thereto flange. The flange has a plurality of grid-like mutually arranged transverse openings for receiving the fastening means.

From the DE 36 37 453 A1 is a splash catcher for installation in truck fenders known to prevent the rainwater runway laterally emerging spray water mist of circumferentially short trained single and double tire seats or Abdeckmuldenkotflügeln in two- or multi-axle vehicles. For the double wheels of a double axle two semicircular trained truck short fenders with built-in and also lying between them fender-free space overlapping spray catcher. In the fender-free space of the sprayer is covered with a cover plate. At a front, open side between the inner edge fender plate and spray water catcher base, a locking plate may be attached by clips to prevent uncontrolled leakage of water spray directly in front of the covered by the truck fender wheel.

From the DE 20 2011 051 494 U1 a fender is known for attachment to trucks or truck trailers. The fender has a Radhauskörper to cover one or more vehicle wheels. The wheel house body is designed such that in the region of its upper side at a local recording a corresponding in shape and size insert element is on or can be placed. The recess is closed at the edge, and the insert element is a tread element on which a fixing element is designed as a latching nose.

OBJECT OF THE INVENTION

The invention has for its object to show a multi-part in Radumfangsrichtung truck fenders with the features of the preamble of independent claim 1 and a truck equipped with a pair of such truck fenders, in which costs are saved without the functionality of the truck fenders in terms of usability with and without truck semi-trailers or superstructures.

SOLUTION

The object of the invention is achieved by a wheel peripheral multi-part truck fenders with the features of independent claim 1 and by a truck with a truck frame and a pair of two such truck fenders with the features of claim 10. The dependent claims 2 to 9 relate to preferred embodiments of the truck fender according to the invention.

DESCRIPTION OF THE INVENTION

An inventive in the wheel circumferential multi-part truck fender has a to be fixed to a truck frame, front in the direction of travel first plastic molded body, to be fastened to the truck frame, in the direction of travel second plastic molded body and a releasably secured to the first and the second plastic molded body , in the direction of travel middle third plastic moldings on. The third molded plastic body has in a front in the direction of travel and in a rear direction in the direction of travel contours on its underside, which engage under horizontal positive engagement at complementary terminal contours at the upper ends of the first and second plastic moldings. First detachable fastening devices hold the third plastic molded article from above on the first plastic molded article, and second releasable fastening devices hold the third plastic molded article from above on the second plastic molded article. At least the first and the second fastening devices engage the third plastic molded body with the first plastic molded body or the second plastic molded body.

The fact that the connection contours on the underside of the third plastic molded body and the complementary terminal contours are in a horizontal positive engagement at the upper ends of the first and second plastic moldings, only means that this positive connection between the terminal contours is effected in their entirety and only relative displacements of the third plastic molded body prevented relative to the first and the second plastic molded body in the horizontal. In particular, neither a complete positive connection alone between the first or the second plastic molded body and the third plastic molded body is required.

In the truck fender according to the invention, the third plastic molded body is releasably locked at least on the first or the second fastening means with the first and the second molded plastic body, so that at least no additional tension bands as part of the releasable fastening means of the third plastic molded body to the first or the second plastic molded body needed. The locking ensures a play-free attachment of the third to the first and second plastic molded body. The departure of tension bands at least between the first or the second plastic molded body on the one hand and the third plastic molded body on the other hand in favor of locking is based on the finding that the frequency with which the average plastic molded body is removed and reassembled in a multi-part truck fender, if necessary, comparatively low is. Accordingly, the releasable fastening devices are subjected to only a small alternating load, which is to be handled without separate tension bands of elastomeric material. Even if the releasable fasteners provided for locking should be overloaded during the service life of the truck fender, it is unlikely that this will result in higher spare parts costs than previously saved by dispensing with the separate tightening straps. It should be noted that with frequent mounting and dismounting of the third plastic molded body, not only the risk of damaging the clamping bands, but also the risk of losing these straps, which in their implementation affects the operating costs of each truck.

The risk of loss of fastening devices is completely eliminated if the first and / or second fastening means, which are designed for locking, are formed integrally with the first and the third plastic molded body or integrally with the second and third plastic molded body. As a result, the maximum savings in the production of releasable fastening devices is achieved.

Ideally, at least the first or second fastening devices are designed such that they automatically engage the third plastic molded body when placed on the first plastic molded body or the second plastic molded body with the first plastic molded body or the second plastic molded body. It does not need anybody special handles more to make this latching.

Basically, the latching of the third plastic molded body at least with the first or the second plastic molded body but also by separate locking elements, such as depressible and latchable and after a Entrastbewegung again retractable, while preferably movably secured to the third plastic molded body latching pins are effected. These locking bolts can be simple plastic injection-molded parts which, when the first, second and / or third plastic molded body are produced, are also integral with this, d. H. can be made via tear-offs connected to this.

Preferably, at least the first or second fastening means on two spaced transversely to the direction of travel latching configurations. Hereby, an increased positional stability of the latched third plastic molded body is achieved. Ideally, however, each individual locking configuration is already sufficient to securely hold the third plastic molding on the first or second plastic molding.

Specifically, each locking configuration of the first or second fastening devices may have a latching lug on the first or second plastic molded body or the third plastic molded body, which engages behind a latching edge on the third or first or second plastic molded body. Preferably, the respective latching nose engages transversely to its latching direction in a form-fitting manner into a recess, at the edge of which the respective latching edge is formed.

The indication of direction "transversely to its direction of rerouting" belongs to the adverb "positively locking". In other words, a positive connection between the latching lug and the recess is achieved transversely to the latching direction, wherein the edge of the recess at the same time forms the respective latching edge. The locking lug thus holds the plastic moldings not only on the locking edge together, but also stabilizes their relative position in other spatial directions.

Preferably, the respective recess, in which engages the respective locking lug, edge-closed, d. H. also limited on the opposite side of the locking edge. Alternatively or additionally, it has a closed bottom. That is, the recess may also be formed in the region of the wall of the respective plastic molding and means no breakthrough of the same.

The locking lugs of at least the first or second fastening devices, however, are preferably formed on elastically deflectable extensions of the respective plastic molded body. Preferably, they are thereby formed on the third plastic molded body, because then, without this third plastic molded body is mounted, no projections protrude with locking lugs at the upper ends of the first and second plastic molded body.

The locking of the third plastic molded body only with the first or the second plastic molded body can be solved by swinging the third plastic molded body, even if this requires a lot of free space upwards. However, it is preferred if the free ends of the elastic extensions on which the latching noses are provided, are manually or at least with a tool deflected to push out the latching noses from their locking engagement. This disengagement of the locking lugs from their locking engagement allows subsequent removal of the third plastic molding of the first and second Ku nststofffo rm body.

In a truck according to the invention with a truck frame and a pair of two truck fenders according to the invention, the first and second plastic moldings of each of the two truck fenders are attached to the truck frame, and the third plastic molded body is detachably attached to the first and second Attached plastic molded body, said attachment comprises at least on the first or second plastic molded body a latching.

Advantageous developments of the invention will become apparent from the claims, the description and the drawings. The advantages of features and of combinations of several features mentioned in the description are merely exemplary and can take effect alternatively or cumulatively, without the advantages having to be achieved by embodiments according to the invention. Without thereby altering the subject matter of the appended claims, as regards the disclosure of the original application documents and the patent, further features can be found in the drawings, in particular the illustrated geometries and the relative dimensions of several components and their relative arrangement and operative connection.
