Device for lifting and holding the Engine in motor vehicle

The invention relates to a "Ygrricütüäg for the Hwmä of the engine in the motor vehicle, in particular in a passenger vehicle.

During a re ^ ^ of assembly, maintenance and repair work on a motor vehicle it is necessary to remove the engine from its bracket and from parts connected to it, such as the gearbox, to be solved and then in the engine compartment, but still with a certain distance to the other units or Keep sharing.

It is known to use stationary overhead traveling cranes or mobile boom cranes for this purpose. Overhead traveling cranes and boom cranes are relatively complex and expensive devices. For this reason, they are often not available in smaller companies. Even where they are available their use often does not make sense, since they are used for the stated purpose for the duration of the respective work £ * »£» asderea use, are blocked.

The invention is based on the task to be simple and easy biliie * V ^ s = JFi «üiuäs SU = Hsbsu rsid Halts« dss engine? i «Kr *« "* vehicle to sohaffen.

According to the invention, this task is solved by an im essential horizontal girder with one support strut each at both of its ends, by an "approximately in the middle of the Support vertically adjustable spindle, at the lower end of which the ends of at least one rope or chain loop are releasably attached, by means for vertical Blocking of the spindle and by an essentially horizontal foot supported on parts of the motor vehicle as the inner edge of each support.

The device according to the invention knows from few and simple individual parts and is therefore particularly economical. It is with its PUssen on parts of the chassis or there Body of the motor vehicle on both Seiton odor before and Supported behind the engine «Suitable, essentially horizontal support surfaces can be found on almost all types of motor vehicle Motor laid and attached with their ends to the spindle. The spindle is then adjusted as far as it is flat to loosen the connections between the motor and the chassis or the body and the other parts of the motor vehicle is required. After loosening these connections the motor is raised to the desired height by means of the spindle and held there by the device for as long as desired.

In an advantageous embodiment of the invention, it is provided that the means for vertical adjustment of the spindle are a cylinder with a pressure-impacted piston). Yes

Compound with a source of druok oil, which is generally in siser Kyftf-fcfaJirasetiewerketAtt is vorbanden, borrowed this training di · handling of the device. Tue Wednesday to * vertical adjustment of the spindle can also be used Threaded bushing attached to the carrier in which the threaded spindle is mounted * and a lever for Turning the spindle «This represents a particularly advantageous embodiment of the invention because of its harmony dar »

The area of use of the invention can be enlarged, as in a further development, since the Support struts are attached to the girder and can be moved in the longitudinal direction of the girder the Ves ^ rlöutusg used for several different · »· vehicle types in which the support surfaces have different distances from one another. The device becomes a particular one The distance is adjusted by »the fixed connections between support struts and girders are released, the support struts in a suitable distance from each other and then reattached.

In this way, a height adjustment of the carrier can be achieved achieves r-erdem that every fun in «an associated support» strut Lösι ir attached and is displaceable in the vertical direction. Di _uroh it is possible to perform a-aeh on to support lower support surfaces, level there ·· from the front » especially long support struts to be provided in brauohei

To protect the paint on the supporting surfaces of the motor vehicle In a further advantageous embodiment, each foot can be provided with a soft surface on its support surface. stranding is «'

An embodiment of the invention is shown in the drawing and is explained in more detail below «

In the illustrated embodiment, the carrier 1 consists of a straight square steel tube · In the middle of the carrier is a hole on the top, into which a threaded bushing with an internal thread is inserted and shrinked. Below ler threaded bush 2 is a DurchgangsIoeh in the carrier 1. ^{A spindle 3 with an} external trapezoidal thread is screwed into the threaded bushing 2. The spindle 3 can be easily rotated in the threaded bushing 2, whereby the pitch of the threaded bushing 2 and spindle 3 is small enough to ensure that the spindle is self-locking in the event of a tensile load.

In the vicinity of each brew of the carrier 1 there is a support strut k-, Di "" * has at its upper end a U-shaped piece 5, in the open side of which the carrier profile fits. Threaded bolts 6 are welded to the two side flanges of the misshapen piece 5 and protrude beyond the top of the carrier. A plate is placed on the two threaded bolts 5 of a support strut and tightened by means of wing nuts 7. In this way, each support strut is positively and detachably connected to the carrier . "

The support strut h consists in its middle section of a tube 8. On this tube, a bushing 9 is slidably arranged, on the outer surface of which the foot 10 ang is simmering. Each foot 10 is supported on a suitable support surface 11 on the body of the motor vehicle. The tube 8 is secured against slipping downward on the socket 9 by means of a pin 12. For this purpose, the tube 8 has a

Number of holes 13 at different heights, through which the pin 12 can be inserted, which is secured in its position by a spring.

At the lower end of the spindle 3, a bracket 14 is attached, the a securable pin 15 carries. The pin 15 is through the last chain links at the ends of a chain loop inserted and connects the chain loop in this way with the spindle 3. Tn of the chain loop 16 hangs a motor 17, shown only schematically.

To turn the spindle 3 and thus to adjust it in a square wrench 18 is used in the vertical direction a square is attached to the upper end of the spindle.

The device described is used in the following way: After loosening all four wing nuts 7, the two support struts k are pushed at such a distance from one another that the feet 10 can be placed on suitable support surfaces 11. It must be ensured that the spindle 3 is arranged approximately above the center of gravity of the engine. By tightening the wing nuts 7, the support struts are fixed in the correct position. If the distance between the top of the motor and the carrier 1 is too large or too small, the pins 12 are unlocked and pulled out of the tubes 8 and after moving the tubes 8 in the sockets 9 to a suitable height of the carrier 1 in the appropriate hole 13 again secured . The spindle 3 is turned down by means of the square wrench 18 so far that the chain end links of the chain sockets 16 placed around the motor 17 can be placed on the half-pulled pin 15, which is then secured in the bracket 14.
