* Aohs arrangement with Blnselradaufhlngung "

The invention relates to one for motor vehicles, in particular All-terrain vehicles, with a la we · borrowed from · two parallel With existing longitudinal girders taps suitable axle arrangement Independent suspension.

Among other things, with changing requirements, a simple and fast approach Converting such vehicles, for example · Replacing sound parts on the same To guarantee it ^ recommends that you calibrate this driving eye - especially for military purposes - according to the modular system build up. Naturally, the design of the chassis plays an important role in this. For example, the axes of the Vehicle well sugänglloh, easy to dismantle and different Place the frame -depending on the size and distribution of the load-bearing capacity be. Furthermore, their training must take into account the structural conditions on the drive system - such as the drive train, differential gears and drive shafts, or an additional Carry existing float cover. After all, supposed to the Aoheteile -a slight salmon stroke of the appropriate Spare parts, see below, and a large variety of types, see below rermeiden- both for rersehledene Fahrseugtypen as auoh -within a vehicle · - for different purposes · »see B. steered axles, unguided axles etc. must be used.

and if necessary near the open top middle part with each other Connected.

Such an arrangement allows for a unit without any further different parts of the frame «detachably attach below. Prevention the feeder parts are screw bolts and Nuts attached directly to aa frame · however, bs is also a Direct arrangement of the middle part on the tap is conceivable, with the support parts either only on the middle part or both on the latter can also be attached to the Rahman. In all In the above cases it is possible to assemble or dismantle the axle assembly as a unit or the carrier parts one-off depending on the needs.

There is a particular advantage of the axle arrangement according to the invention furthermore "that it is suitable for both a steered and unguided Aohee". In the latter case the tie rod only replaced by a locking bar that is adjustable in length be used for driven struggles «are therefore expedient for the implementation of the drive shafts in the carrier parts Provide recesses. In general, you will have a middle part between the two support parts approximately in the middle the same, but for an arrangement with driven wheels it is more advantageous to have two middle parts - each around the Edge of the support parts- rorsuaehen? there eioh then the differential gear and the waves well «wipe the two central points accomodate bsw« have it carried out *

In addition, the arrangement according to the invention is also suitable for a floating vehicle or for converting a stretcher vehicle into a floating vehicle. For example, an arrangement of a Sohwiamwanne is recommended so that it encloses the middle part of the upper part of the body and is clamped between the last and the supporting parts, so that the central part of the body is also stiffened like a spine ^; M '■■■ - represents Anne.

Bel driven axles must of course be included in the Sohwimawanne recesses are provided on the implementation of the drive shafts, whereby the seal is part of the gasket double diohting or the like takes place

Another gate part of the axle arrangement according to the invention geeohloeeene unity consists in the fact that all external forces on the axle arrangement -i.B. due to unevenness of the road caught by the Aohs arrangement itself and not passed on to the vehicle frame · Merely acceleration-bsw. Braking forces are transmitted to the vehicle frame through the axle mounting bracket. Set this function of the axis arrangement naturally also a firm and solid development of the same »especially of the middle part, τοraus. Its preferred embodiment the invention therefore provides that the smock part Trapeze-like downward converging, old la essential has double-T-shaped cross-section rersehene legs and the outer support parts are plate-shaped and correspondingly the legs of the middle part are inclined

Oa the two legs of the central part are essentially one another have to accommodate opposing Biegeaoaente, suggests the Invention for a further stiffening of the middle part ror that swisohen the two loops of the middle part -at their upper ends- a pressure rod is arranged.

Among other things, I should avoid a large variety of types - as already mentioned above mentioned - the invention sees that the two outer carriers parts and also the wheel suspensions on both wheels are designed the same. The design of the wheel suspensions is included gänslioh la the discretion of a designer. For example, conventional longitudinal or 8-sided links would be conceivable as wheel guide members.

Torsugsweiss sole is the invention of the gate as a wheel guide member in known to sioh quietly one upper and one lower triangular wishbone is red and that on a wishbone each a lever link ezsentrieoh su its rotary

Such wishbones have the gate part "that el""ittele corresponding eyes can be hinged directly to the outer support parts. With regard to the articulation of the wheel guide members on the outer support parts as well as on the wheel carriers, the invention provides that the bearings for the wheel guide members are designed as threaded bearings in the well-known manner and are almost entirely soldered. The above-mentioned measure enables a partial use of the Aoheanordnung for buoyant · Fahrseuge _f whereby even «if the Fahrseugee la water is longer ·· The Fahrseugee la water does not have a negative effect on the above-mentioned bearings Half of the division has been achieved, but is largely redeemed in the replacement of the wheel guide members due to bearing damage.

By means of the above-mentioned lever members and the rigid connecting member It works in a simple way in wheel pressure compensation between realize the baths of the same Aohse, which for a good Driving behavior of · vehicles · in rough terrain is essential is. As a rigid connecting member, for example, a known hydraulic system or preferably one in your system Length adjustable push and pull rods can be used. at Driving on normal roads can simply lock the wheel pressure compensation by locking the push and pull rod. take place.
