Detailed description of the invention
Embodiment:
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, a kind of spare tyre lifter housing structure, comprise upper shell 1 and lower house 6, described upper shell is a U-shaped metal shell, described upper shell end face two ends are provided with upper shell mounting hole 18, described upper shell end face middle part is provided with lower house knock hole 19, and before and after described upper shell, middle part, two sides is provided with lifter camshaft shaft hole 20,21, and before and after described upper shell, bottom, two sides is respectively provided with two buckle mounting holes 22, described lower house is a rectangular ring plastic casing, described lower house is arranged in described upper shell, described lower house bottom surface dual-side is respectively provided with two buckles 8, described buckle and corresponding the connecting and fixing of described buckle mounting hole, described lower house end face middle part is provided with the positioning convex corresponding with described knock hole 10, described positioning convex and described knock hole are pegged graft and are located, described lower house end face both ends are provided with square nut deep gouge 13, described nut deep gouge is corresponding with described upper shell mounting hole, described lower house bottom surface is provided with a criss-cross chain entrance hole 12 and an oval chain leadout hole 23, described upper shell front-angle end is provided with a pull back spring fixed card slot 17.
Tradition spare tyre lifter upper and lower casing is generally metal construction, by punch forming.Upper shell passes through flanging, and in flanging punching, by four pairs of fastening assemblies, spare tyre lifter is assemblied on the wheel support of vehicle frame.Lower house Main Function is installation and the location of restricted internal transmission component, and inner transmission component is protected.Upper shell of the present utility model is metal construction, and by punch forming, lower house is plastic material, lightweight.Upper shell Main Function is installation and the location of restricted internal transmission component, and inner transmission component is protected, and the effect of lower house is only for to carry out closed protective to inner transmission component.The utility model unit construction is simple, and lower house is Plastic Parts, and quality is lighter compared with conventional confguration.Upper shell and lower house form the space of a relative closure, reduce the area that the inner transmission component of spare tyre lifter directly contacts with outside air, lubricating oil evaporation rate is reduced, and intraware is slowed down by the speed of corrosion, the phenomenon of simultaneously having avoided sandstone to enter intraware occurs, thereby extended the service life of spare tyre lifter.
Four buckle mounting holes offering on the buckle of lower house structure of the present utility model bottom by lower house itself and upper shell are fixed, without other secure components, simple to operate, lower house top positions by the knock hole at positioning convex and upper shell top, and positioning precision is higher.
The utility model is exposed to outer driving tooth wheel seat pull back spring 16 by conventional confguration and protects among housing; avoid Stone Shock to cause the possibility of deflection of spring, inefficacy; pull back spring in prior art is improved to notching construction at the spring mounting hole of upper shell is fixed card slot simultaneously, has simplified the installation of spring.
The criss-cross chain entrance hole that lower house of the present utility model bottom surface is provided with is by the fashionable direction of restriction chain roll, avoid existing angle that clamping stagnation occurs due to chain and driven gear chain, make spare tyre lifter lifting more smooth and easy, improved conventional confguration lower house to the rigid wearing and tearing of the metal between chain surface simultaneously.
The square nut deep gouge of lower house end face of the present utility model is for placing two square nuts that match with the bolt assembly 9 of fixing upper shell, when assembling lifter assembly, directly be connected with square nut through upper shell mounting hole with fastening assembly, spare tyre lifter assembly is installed on vehicle frame, has simplified the assembling of spare tyre lifter assembly.
