Description

RECORDING DEVICE FOR MOTOR VEHICLE GROUPS

The present invention relates to a receiving device for motor vehicle assemblies, in particular for units of commercial vehicles in order to enable fast, safe and flexible removal and installation of the modules.

For the installation and removal of heavy, bulky motor vehicle assemblies usually lifting devices are used, which are provided with a receiving plate and other fasteners for receiving the modules. For the expansion of large units, in particular transmissions of commercial vehicles, known from the prior art pit jack, on the for receiving a commercial vehicle unit, a so-called. Gear plate is mounted on the vertical support of the pit lift. Such a receiving device can be universally used for a variety of assemblies, which generally differ greatly in terms of dimension, shape and weight. For receiving and fastening heavy, truncated-cone-shaped commercial vehicle transmission usually other auxiliary elements such as wooden blocks, receiving claws and Befestigungsspannbänder or chains are used to support the gearbox on the plate or lash down.

For more accurate positioning of the receiving plate on the male unit pivotable mounting plates are known from the prior art continue. However, up to 1,000 kg heavy commercial vehicle units can easily tilt or slip when using such gear plates or require a time-consuming lashing and attaching the unit by means of additional straps or safety chains. In addition, the removal and installation of such assemblies by means of the above-mentioned receiving devices by the usually severely limited mobility and the limited space available in labor pits in conjunction with Mehrstempelhubanlagen or pit lifts difficult and usually leads to tedious positioning and alignment procedures before the transmission can be received on the receiving plate. It is therefore desirable to form a receiving device with the lowest possible height. For safety reasons, the use of known from the prior art pit lifts with gear plates usually also requires the costly use of two Werkstattmitarbeiter for positioning, securing and mounting the gearbox on the transmission plate.

It is therefore an object of the present invention to develop a Aufnahmevorrich- device with low overall height for motor vehicle assemblies, in particular for units of commercial vehicles, which allows a quick and secure recording of heavy and often soiled assemblies. It is a further object of the present invention to provide a highly flexible receiving device for use with pit lifts, which can be easily adapted to the variety of different dimensions, shapes and weights of different assemblies reliable.

These objects are achieved by a receiving device according to the features of patent claim 1. The dependent claims relate to advantageous embodiments of the invention.

According to the invention, the receiving device for motor vehicle assemblies comprises a receiving carrier and at least one receiving element fastened on the receiving carrier. Furthermore, the receiving device comprises a first pivoting mechanism of the receiving carrier consisting of a first scissor lifting element and a first carrier arm, wherein the first Scherenhub- element is connected to the receiving carrier and a first end portion of the first support arm and wherein a second end portion of the first support arm at the top thereof articulated with the recording medium in connection. A receiving device in the context of this invention is thus a receiving device, which is used in conjunction with a designed as a linear actuator vertical carrier, for example, a so-called. Pit Jack, and is connected thereto. Such a vertical carrier designed as a linear actuator, for example a pit lift, is known from the prior art, designed in the usual way and not further described.

A pivoting mechanism of the receiving carrier allows a pivoting back and forth or tilting or tilting of the receiving device from the horizontal, to position the receiving device as close as possible to the component to be installed or removed. The scissor lift element is designed as a scissor lever. The pivoting mechanism according to the invention consisting of scissor lifting mechanism and articulated lifting arm allows flexible adaptation to a wide variety of assemblies (for example, truncated cone-shaped gearbox) with low height and effort. The use of the pivot mechanism according to the invention enables a reduction of the required lifting forces by the use of a long lever arm (support arm), while the scissor lift in the retracted state has a very small footprint and thus has a low overall height of the receiving device allows.

According to the invention, the receiving device may comprise a second pivoting mechanism of the receiving carrier having a second scissor lifting element and a second carrier arm, wherein the second scissor lifting element is connected to the receiving carrier and a first end portion of the second carrier arm, and wherein a second end portion of the second carrier arm at the top thereof articulates with the Receiving carrier is connected and is pivotally connected at the bottom with the top of the second end portion of the first support arm. In this case, the second carrier arm can be arranged perpendicularly or substantially perpendicular to the first carrier arm. The thigh joints of the first and second support arm can be arranged rotated 90 ° to each other. The arrangement and mounting of the two support arms enables a 3-dimensional pivoting movement of the receiving device about a central pivot point of the receiving device.

Thereby, a second pivoting movement of the receiving device is made possible perpendicular to the first pivoting movement. The arrangement according to the invention of the two support arms one above the other and offset by 90 ° relative to one another results in a particularly low overall height in combination with the two scissor lift elements, while at the same time reducing the force required due to the long lever arms which simultaneously serve as a stabilizing element of the mounting plate.

Furthermore, the first carrier arm may be longer than the second carrier arm. Furthermore, the first end region of the second carrier arm can lie vertically below the first end region of the first carrier arm. In other words, the second support arm is steeper than the first support arm toward the first end portion which communicates with the scissor lift member. This inventive arrangement and expression of the support arms allows a compact possible dimensioning of the receiving medium to be pivoted at the same time as strong lifting force.

The lower edge of the second support arm preferably forms with the horizontal an angle between 10 ° and 35 ° degrees, more preferably an angle between 15 ° and 25 ° degrees.

The pivotal movement of the first pivot mechanism performs a pivotal movement of x °, where x is preferably in a range between 20 ° and 40 °, more preferably in a range between 25 ° and 35 °. The pivotal movement of the second pivot mechanism allows a Pivoting movement of ± y ° with a pivot axis perpendicular to the first pivoting movement, wherein y is preferably in a range of 10 ° and 20 °, more preferably in a range of 12.5 ° and 17.5 °. Preferably, the thickness of the first support arm decreases from the second to the first end portion. In other words; the support arms may be wedge-shaped and taper towards their outer end. This shape offers an optimal compromise between carrying stability and freedom of movement at the outer ends for exerting the pivoting mechanism.

Preferably, the receiving element is fastened with a detachable plug connection on the receiving carrier. This allows the use of different recording elements, which are adapted to the purpose and the shape and size of the component to be installed or removed and can be changed as easily and quickly.

Preferably, the receiving elements are pivotally mounted in order to adapt as flexibly as possible to the shape and size of the male assembly. Preferably, the receiving elements 15 ° are pivotable about a horizontal axis.

Preferably, the receiving elements have a convex shape. Preferably, three convex receiving elements are used, more preferably four convex receiving elements are used. The convex receiving elements with a rounded receiving surface thus enable a particularly stable and secure reception of truncated cone-shaped (conical) commercial vehicle transmissions. For the most secure and non-slip receiving the modules, the receiving elements may be provided on the receiving surface with a rubber coating. Furthermore, the receiving element can be attached to different locations of the recording medium. Preferably, the receiving carrier has at least two connecting elements for each releasable plug connection of the receiving element. This allows a flexible adaptation of the receiving device to the shape and size of the assembly to be accommodated. Furthermore, instead of a releasable plug connection, the receiving element or the receiving elements can also be mounted displaceably on the receiving carrier, for example by means of a guide rail mounted on the receiving carrier.

Furthermore, the recording medium may consist of four square tubes arranged in a plane, two of which are arranged parallel to one another and in each case perpendicular to the other two square tubes. This allows a particularly high carrying stability with high freedom of movement in the inventive arrangement of the square tubes, preferably two opposite square tubes are mounted closer to the vertical support shaft, so that the recording medium forms the shape of a "Roman two".

The lower side of the first carrier arm can have a fastening element for rotatable contact with a vertical carrier designed as a linear actuator. The underside of the support arm can also be mounted on a rail device, for example, to move the receiving device horizontally in a lifting pit. In this case, the vertical movement of the receiving device can be carried out exclusively by the scissor lifting elements.

In summary, the present invention provides a receiving device for motor vehicle assemblies which, by means of the pivoting mechanisms according to the invention in combination with the releasable and displaceable receiving elements, which are at the same time likewise pivotable, can be quickly connected to the various shapes and sizes of modules to be installed or removed can be adjusted. In particular, heavy, conical commercial vehicle transmissions can be safely installed and removed with the recording device according to the invention. The carrier element according to the invention in combination with the pivoting mechanisms consisting of scissor lift element and carrier arms has a low overall height and at the same time high leverage. The recording device according to the invention is therefore universally applicable, easy to handle and allows for easy, safe and fast removal and installation of gearboxes and, in contrast to common Aufnahmevorrichtun- conditions also reliable operated by only one person.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying schematic drawings.

Fig. 1 shows an exploded view of the receiving device according to an embodiment of the present invention. The receiving device 1 has a recording medium as a connection between the pivoting devices and the receptacles 20 for the units. The support structure consists of welded square tubes 14, 15, of which two square tubes 14 are arranged parallel to each other and each perpendicular to the other two square tubes 15 are. The square tubes 14, 15 shown in Fig. 1 are flattened at the Längskannten and have there additional four narrow longitudinal edges. At the outer ends of the square tubes 14 are on the top of fasteners 11 in the form of collar drilling bushes which are pressed into the square tubes. As a result, a cost-effective, secure plug-in system is realized that at the same time prevents possible plastic deformation of the square tubes. The collar drill bushings 11 serve to receive the receptacles 20. The square tubes 14 have eight collar drill bushings, so that a receptacle element 20 can be inserted into the most suitable collar drill bushing 11, depending on the size and position of the component to be accommodated. On the top of the square tubes 15, a bearing plate 16 is mounted, which has on its underside in a central position of the receiving carrier 10 plain bearing bushes 13. The plain bearing bushes 13 are pivotally connected to a sliding bearing pin 62 of the second support arm 60 and thus allow a pivoting movement of the recording medium from the horizontal. This sliding bearing improves the sliding and wear properties of the receiving device when executing the pivoting movement, wherein the axial load is added to this bearing by a collar on the sliding bearing. At one end of the support plate 16, a fastener 17 is further attached for attachment of the upper tip of the second scissors 50. The connecting element 17 is designed as a simple bearing point and not provided with sliding bushes, since the scissor lever 50 only a small pivoting movements (± 15 ° ). The connecting element 17 is aligned during mounting to prevent distortion and consequent jamming in the scissors mechanisms.

In Fig. 1, as well as in the views of Figs. 2A, 2B, 2C and 2D a trained as a first support arm 40 base support is further shown as a connecting element between a pit lift (not shown) and the rest of the receiving device. The first carrier arm 40 has a wedge-shaped, to the first end portion 41 tapered support 44, which has a high load-bearing capacity with minimum space requirements. The carrier 44 is designed as a fuel cutting part made of solid material and machined to ensure requirements with respect to the shape and position tolerances and the surface requirements.

The support arm 40 is mounted with a receiving element 43 on a pit lift (not shown) and rotatably mounted about this. As shown in Fig. 2D, a receptacle 43 is selected, which still encloses the pit lift cylinder outside. As a result, the connection can be supported on the inside and outside of the cylinder and thus reduces the Materia Ibeanspruchung. The receptacle 43 is positioned by a connector and partially supported and welded to the support all around. The pit lift cylinder outside additionally enclosing shape of the receptacle 43 thus allows a particularly secure attachment of the receiving device 1 to the pit lift despite the high bending stresses occurring of about 500 N / mm ² . The outwardly wedge-shaped support 44 has, as shown in Fig. 2B, at its outer end a flat, straight end portion 45 on which a slide bush 41 is mounted, which is pivotally connected to a lower end of the first scissor lift member 30.

In the second thick end portion 42 of the first support arm 40, this has a solid hinge pin, which is secured by a groove and a threaded pin against displacement in any direction. This hinge pin is hinged to a sliding bushing of the second end portion 62 of the second support arm 60. The second support arm 60 is thus hinged to the first support arm 40.

The construction of the second support arm 60 is shown in more detail in Figures 3A, 3B and 3C. The second support arm 60 connects as an intermediate support the base support 40, the scissors mechanisms and the receiving carrier 10 with each other. The length of the second support arm 60 is shorter than that of the first support arm 40. The support member 64 also has a wedge-shaped shape that tapers outwardly. In comparison to the carrier element 44, however, the carrier element 64 is more steeply sloping downwards. The end portion 61 of the second support member 64 is lower than the corresponding end portion 41 of the first support arm 40. The lower edge of the second support arm 60 forms an angle of 21 degrees with the horizontal.

At the outer end of the second support arm 60 is again a flat, straight end piece 65, on which a slide bushing is mounted. The slide bush is connected to the lower end of the scissor lift member 50. The second carrier arm 60 is connected via a hinge pin with the receiving carrier via the receiving element 13. This bolt 62 is secured against displacement by a groove and a threaded screw. The carrier 64 is also a flame cutting part, which is subsequently machined. As can be seen in FIG. 3B, chamfers 67 are located at the hinge points in order to reliably avoid a collision with the receiving carrier 10 during the pivoting movement by the beveled surfaces on the workpiece edge. The scissor levers 30, 50 shown in Fig. 1 are moved together and apart via a threaded rod with right and left-hand thread. The threads are machined from a round material; this makes it possible to design the transition between the threaded rods as short as possible, with high train and Torsionsbelastung and the lowest possible cost.

The threaded rod 31 is driven by means of a hydraulically driven ratchet (not shown). This drive mechanism is compact and provides sufficient torque. The connection is made by a hexagon whose nut is milled in solid material. To avoid over-tightening or overloading due to over-tightening, countersunk shafts are mounted on the opposite sides of the drive. The swivel mechanism is driven by a pneumatic ratchet. But it can also be a manually operated ratchet used. The corner joints of the two scissors levers 30, 50, ie the components between the shear arms and the threaded rod or the carriers, are made without sliding bushes. The entire corner joint consists of a copper alloy, which has particularly good sliding properties, high wear resistance, and high corrosion resistance. In addition, so-called lubricating nipples are attached to the connections in which the threaded rod runs in order to minimize the driving force and the wear at this point. In addition, an undercut is attached to the connection of the shear arms to make the transition soft and thus to avoid cracking at this highly stressed site. The scissor arms are formed without teeth, as tilting is already sufficiently avoided by the support joints.

The first pivot mechanism consisting of the first longer support arm 40 and the first scissor lever 30 allows a pivoting movement of 30 °. The second pivot mechanism consisting of the second shorter, steeper support arm 60 and the second scissors lever 50 allows a pivoting movement of +/- 15 °. The two pivot axis are perpendicular to each other.

The receiving elements 20 shown in Fig. 1 have a rounded support surface in the form of a rubber cover 21. The bearing surface can be swiveled by 15 ° about a horizontal axis and can thus be used flexibly with regard to the dimensions and shape of the assemblies to be picked up.

For pivotable embodiment of the receptacle 20 are bending parts that are welded, used. This sheet metal construction is attached to the Aufnahmekotz with a bolt and two lock washers. To ensure the most secure possible absorption of the aggregates, a rubber plate of the quality NBR with a hardness of approx. 65 Shore A is used as the support surface. The receptacles 20 are inserted by means of the locking pins 22 in the Bundbohrbuchsen 11 of the support member 10.

Instead of the convex receiving elements 20, as shown in Fig. 1, alternatively pluggable, flat truss receptacles (not shown) can be used, which have a long, flat receiving element, which at its two ends via two locking pins 22 in the Bundbohrbuchsen eleventh the support member 10 are inserted. Such a truss receptacle is particularly suitable for being able to receive flat, non-conical aggregates well and safely. The recorded aggregates can additionally be secured with tension straps (not shown). The exemplary embodiment illustrated in FIG. 1 is shown again in FIG. 4A in a front view for better understanding, in a side view in FIG. 4B, in a perspective view in FIG. 4C and in a plan view in FIG. 4D.

Of course, the individual features of the invention are not limited to the described combinations of features in the context of the presented exemplary embodiments and can also be used in other combinations as a function of predetermined device parameters.
