DE2800806A1 - Lorry spare wheel carried horizontally in centre on plate - is swivelled by hand crank into vertical position on road to side of vehicle - Google Patents

Abstract

The arrangement is intended for holding in horizontal position and placing on the road surface in vertical position of a tyred spare wheel of a lorry. It comprises a carrier plate (1) fixed to the wheel, which can be swivelled about an axis (3) parallel to the longitudinal vehicle axis and is slidable on transverse rails (4) between end stops (10, 5). The slide and swivel motion is actuated by a spindle (8, 9) or rack with hand crank (7) or by hydraulic means. The plate has vertical arms (1a, b) with rollers (2, 3) running on the lower flange (4a) of the rail. The flange has a projection (6) near the outer stop (10) and an opening for the roller (2) to pass through, allowing the plate to swivel down as it approaches the stop (10). The spindle is held on the chassis at one end, the other end being pivoted to the plate.

Description

Patent description

Spare wheel holder for motor vehicles and trailers Addition to the patent application P 2? 25 611.7 In the patent application P 27 25 611.7 there is a spare wheel holder described, in which the uninterrupted rotation of a hand crank alone Spare wheel transported from the middle of the vehicle to the edge of the vehicle, then from the horizontal or horizontally similar transport position to an inclined vertical one Mounting position swiveled and vice versa - by changing the direction of rotation of the hand crank -can be brought into a necessarily secured transport position.

In the interests of a more extensive use of spare wheel 4EalW stanchions of the same type also for spare wheels of different tire sizes and with different Rim designs - with further independence from the vehicle's state of charge - In this additional application, the wheel holder (1) has special designs and devices with functional features described below and shown in the drawings.

A key feature of this wheel holder (1a, 1b, 1c) is an angled, than Wheel well, trough-shaped foot. This foot is used for recording and preliminary Fixation of the wheel, which can be rolled up in a vertical position. That way learns the attachment of the wheel or its loosening a significant simplification, since it is in in this always vertical position without additional support and both hands of the operator for the screw fastening.

Wheel holder with double screw fastening (Fig. 1) This wheel holder (1a) are assigned at least two screw fasteners of known design, which also the STVZO demand for double securing of the spare wheel and off two clamping brackets; with the associated screws can exist.

Wheel holder with wheel cage (Fig. 2) This wheel holder (lb) has at least three clamps (14, 15, 16). A clamping bracket (16) is pivotably arranged and opens or closes the wheel cage formed by all brackets. Of the pivotable clamping bracket (16) is against unintentional movements by a known Locking element such as bolt, pin or screw (1,) secured. The second wheel lock - the first is formed by the closed and secured wheel cage - takes over a screw (18) located in the center of the wheel and going through all clamping brackets, which is turned into a thread of the wheel holder (lb). The tensile force of this screw (18) and the pretensioning acting on the clamping brackets (14,15,16) presses the spare wheel against the wheel holder (1b).

Wheel holder with wheel clamp ig.3) One that is partly inevitable This wheel holder (1c) wants to attach a wheel with a minimum expenditure of time when the wheel holder is pivoted, automatically closing wheel clamps are used.

In this embodiment, the wheel holder (1c) is doubled angled foot and a movable head part guided in the Xad holder (1c) (19) formed a wheel clamp, which when turning the hand crank (7) - the with The pivoting of the threaded spindle (9) and tube nut (8) is known Wheel holder (1) causes - closes or opens.

The closing process inevitably takes place through the connection of the spindle system (8,9) with the head part (19) will the Closing force size and in particular the minimum required by the Weight of the spare wheel guaranteed. When operating the hand crank (7), which swivels in the complete wheel holder (lc, 19) with the spare wheel, the tensile forces the threaded spindle (a) transferred to the movable head part (19) and press here the spare wheel against the foot of the wheel holder (1c).

Head part (19) and foot of the wheel holder (1c) are shaped so that they Clamp the tire around the circumference and sides of the wheel and hold it immovably. A screw (18) with a bracket (20) is used as a second wheel lock Execution.

The spare wheel holder is included in all of the above versions their special wheel holders (1a, 1b, 1c), including the wheel holder (1) of the main application, there is of course the possibility, for reasons of equity or other reasons to dispense with the movement of the wheel holder towards the center of the vehicle and on swiveling the wheel holder into a horizontal or similar horizontal position to restrict. In such cases, the guide rail (4) could be dispensed with if the bearing journals of the rollers (3) - as well as the pipe nut (8) or the threaded spindle (9) - should not be stored in the guide rail (4). In such cases, useful pivot bearings on the vehicle frame are becoming more common Directly welded or screwed on. The fastening task of the wheel holder, the was usually oversized by the sliders (2), then a screw or a plug connection of a known type.

Claims (3)

Patent claims 1 spare wheel holder for space-saving and secured Accommodation of spare wheels, after the main registration P 27 25 11.? marked, that it consists of a wheel holder (1), which by uninterrupted rotary movements a hand crank (7) moved longitudinally in a specially designed guide rail (4), can be swiveled and secured, characterized in that the wheel holder (1a) is provided with a trough-shaped foot designed as a wheel trough. 2 spare wheel holder according to claims 1 to 19, characterized in that that the wheel holder (lb) at least three clamping brackets (14, 15, 16) are associated with which a clamping bracket (16) is pivotable, which by a screw (17), bolt or Locking element of known design can be secured against movement. 3 spare wheel holder according to claims 1 to 10, characterized in that that the wheel holder (1c) is designed as a guide part and consists of an additional, movable one Head part (19), which with the threaded spindle (9) or the pipe nut (8) is articulated and that when rotating the hand crank (7) not only the complete wheel holder (1c, 19) is pivoted, but that inevitably and simultaneously the wheel clamp formed from the two wheel holder parts (1c and 19) is opened or is closed, in which a spring arranged between the wheel holder parts (1c, 19) (21) supports the opening process. 7 spare wheel holder according to claims 1 to 12, characterized in that that the guide rail (4) is designed as a pivot bearing and fastening elements known design has the wheel holder in any desired transport position between vertical and horizontal, that of the spindle system (8,9) during the swiveling process will be able to determine and secure.
