Telescopic prop comprising a spindle, and driving said prop by means of a crown wheel comprising an integrated thrust bearing for supporting loads

Abstract

Disclosed is a vertical elongate prop for supporting a parked vehicle trailer (1), consisting of a top prop tube (21), an inner prop member (22) which can telescopically slide into the prop tube, and a threaded spindle (3) for moving the inner prop member (22) in relation to the prop tube (21). The threaded spindle (3) meshes with a threaded bearing (31) that is secured to the upper end of the inner prop member (22). The upper end of the threaded spindle (3) is connected to a crown wheel (32), the upward-facing surface of which is part of a thrust bearing (33) or is designed to accommodate a thrust bearing (33). The thrust bearing (33) is supported on the vehicle trailer (1), either directly or via a cover (23) that is connected to the prop tube (21).

Description

technical field [0001] The present invention relates to a vertically elongated frame for supporting a parked vehicle trailer, the vertically elongated frame consisting of: a top strut tube; an inner strut member telescopically slidable into the strut tube; and A threaded mandrel for moving the inner strut member relative to the strut tube, wherein the threaded mandrel engages a threaded bearing secured to the upper end of the inner strut member. Background technique [0002] When a vehicle trailer, such as a semi-trailer, is to be disconnected from its tow vehicle, vertical brackets mounted on the trailer extend down into the parking lot to keep the trailer in a horizontal position at all times. [0003] In the prior art, telescopic supports are mainly used, which are usually mounted in pairs in front of the frame of the semi-trailer. The telescoping stand almost always consists of a hollow strut tube, outside of which the lower section extends downwards for parking. Since...
