Embodiment Construction

[0018] Depend on figure 1 As we know, the spare tire lifting and fixing device includes a winch mechanism, a steel wire rope spare tire support mechanism and a vehicle body mounting bracket. The winch 14 is welded on the body mounting bracket II12, and the wire rope protruding from the winch 14 is connected to the body mounting bracket I8 through a wire rope conduit 11. , the end passes through the cylindrical rubber and is fixed by the wire rope lock 10, and the cylindrical spongy body 13 is installed on the opposite side of the winch 14, and entangles the big end of the main shaft 7. It has the functions of dustproof and shock absorption. The main shaft 7 drives the eccentric wheel fixed plate 6 and the eccentric wheel 5 to rotate, and the duck plate 4 reciprocates to make the internal meshing gear 1 rotate to tighten or loosen the wire rope, so as to realize the ascent and descent of the spare tire.

[0019] Depend on figure 2 It is a schematic diagram of the internal tr...

Abstract

A spare tire fixing device comprises a winch mechanism, a steel wire rope spare tire support mechanism and a vehicle body mounting support and is characterized in that a spindle (7) drives a eccentric gear fixing plate (6) and an eccentric gear (5) to rotate, a contour plate (4) reciprocates to allow an inner meshing gear (1) to rotate to tighten or loosen a steel wire rope so as to ascend and descend a spare tire. The steel wire rope extends and contracts by rotation of an eccentric gear mechanism in the winch mechanism so as to ascend and descend the spare tire. The winch mechanism has a feature of slipping, feedback can be provided for operators when the spare tire is fixed, and damage, caused by excessive operation, of a transmission mechanism can be avoided. The spare tire fixing device is stable in transmission, simple to operate and low in noise.

Description

technical field [0001] The invention belongs to a lifting auxiliary device for a spare tire of an automobile, in particular to a lifting and fixing device for a spare tire. Background technique [0002] At present, most of the spare tire lifting and fixing devices used on domestic commercial vehicles are chain-type. The spare tire lifting and fixing device is composed of eccentric wheel, sprocket, chain ring, eccentric wheel, housing and spare wheel supporting part. The mechanism is simple, the operation is laborious, the transmission is not stable, the noise is loud, it is easy to get stuck, and the performance is not stable enough. Contents of the invention [0003] In order to overcome the defects of the prior art, the purpose of the present invention is to provide a spare tire lifting and fixing device, which is to realize the elongation and contraction of the steel wire rope through the rotation of the eccentric wheel mechanism inside the winch mechanism, and complete...
