Embodiment Construction

[0034] The following will be described respectively in the figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The exemplary embodiment shown in .

[0035] figure 1 It shows how the drive unit 1 is constructed, and the main components it comprises. The drive unit 1 is based on a chassis 2 made of a profile on which track sections 3, coupling means 4 for coupling to hitch triangles 30 of a trailer or caravan, and means for steering and steering the drive unit can be mounted on on the chassis 2. The profile is dimensioned to support the loads typically applied to hitch coupling structures. Profiles can be extruded, but also welded. The material can be aluminum or steel.

[0036] figure 2 Track sections 3 are shown mounted on each side of the chassis 2 . The track part 3 comprises a motor 10 with a gear 10 a which engages a drive wheel 11 , an idler wheel 12 , at least one support wheel 13 and a track 14 via a drive connection 15 . as ...

Abstract

When, according to the invention, a drive unit for trailers or caravans is ar not ranged such that it comprises a chassis (2) with crawler sections (3), a coupling device (4) having first and second coupling parts (28, 29), said second coupling part (29) being arranged on the hitch triangle (30) behind the normal hitch coupling and behind the nose wheel, and the drive unit additionally comprises means for steering and manoeuvring the unit, a good weight distribution is achieved between main wheel and drive unit, so that it is easy to control the placing of the trailer or of the caravan, without having to worry about the risk of colliding with the neighbour or damaging one's own vehicle.

Description

technical field [0001] The invention relates to a motorized, manoeuvrable drive unit with track parts, which is intended to be mounted especially on hitch triangles of trailers and caravans, which hitch tripods are equipped with hitch Joint structure and front wheel. Background technique [0002] It is well known that frequent maneuvering of a trailer or caravan can cause problems when the trailer or caravan is moving the final distance to where it will be parked or used. The compartments often separate before the trailer or caravan is fully in place, which can be explained by the fact that the driver is inexperienced in performing the necessary maneuvers in the confined space of the location, and by his fear of damaging his own or an adjacent caravan. At the same time, if the supporting structure is soft or irregular, the weight of the trailer or caravan and the size of the obstacle often exceeds the driver's power to maneuver them into place, leading to altercations amon...
