Abstract
The utility model discloses a drive shaft of a microcar, comprising a flange fork, one universal joint assembly, one universal joint fork, an axle tube, another universal joint fork, another universal joint assembly and a slide fork, which are sequentially connected with each other from one end to the other end, wherein a dust cover is sheathed out of the slide fork, and a plurality of clamp springs are arranged between each universal joint assembly and each universal joint fork. The structure of the drive shaft is different form that of a conventional drive shaft, and one end of the drive shaft is designed to be the flange fork and the other end of the drive shaft is designed to be the slide fork without continuously using a structure type with two flange forks at two ends. Under the condition that the performance of the drive shaft meets the use requirement, compared with the conventional drive shaft, the whole drive shaft eliminates one flange fork, is added with one universal joint fork, and eliminates a spline shaft, so that a part with a higher manufacturing cost can be saved in the connection of a whole automobile chassis can be saved, therefore, the cost of the whole automobile is saved, and the weight of a drive shaft assembly is reduced by 10%.
Description
Technical field
The utility model relates to and belongs to the truck drive shaft technical field, is specifically related to a kind of minicar transmission shaft.
Background technique
In the last few years, along with rapid economy development, China had become global first automobile market.In 2001 ~ 2010 years during the decade, the minicar growth that remains a constant speed basically, average growth rate per annum is about 12%, and vehicle driving shaft assembly is one of key components and parts of automobile, is in great demand.And along with the rising of oil price, little car manufacturer more and more payes attention to light-weight design.Traditional minicar transmission shaft is as shown in Figure 1; Comprise flange york 1, universal joint assembly 2, universal-joint fork 3, central siphon 4, splined shaft 5, slip yoke 6, universal joint assembly 7 and flange york 8 that right-to-left connects successively; The dust-proof cover 9 that is provided with tubular in the end and splined shaft 5 joints of slip yoke 6; Flange york 1 and flange york 8 respectively with minicar on gearbox be connected with bolt with back axle, complex structure, the process for machining and manufacturing of this transmission shaft is loaded down with trivial details, weight is big, cost is high.
The model utility content
The utility model is in order to solve deficiency of the prior art, and a kind of simple in structure, in light weight, minicar transmission shaft that cost is low is provided.
For solving the problems of the technologies described above; The utility model adopts following technological scheme: a kind of minicar transmission shaft; Comprise from an end connecting flange york, universal joint assembly, universal-joint fork, central siphon, universal-joint fork, universal joint assembly and the slip yoke of setting successively, outside slip yoke, be arranged with dust-proof cover to the other end.
Be provided with jump ring between said universal joint assembly and the universal-joint fork.
Adopt technique scheme, the utility model is different with traditional transmission shaft structure, and no longer continuing to use two ends all is the conventional construction type of flange york, and designing an end is flange york, and an end is a slip yoke.Under performance satisfies usage requirement; Compare with traditional transmission shaft, whole transmission shaft saves a flange york and increases a universal-joint fork, saved a splined shaft; Like this; Whole automobile chassis connects just can save a cost than higher part, for car load is practiced thrift cost, and makes driving-shaft assembly loss of weight 10%.Jump ring is used for regulating the gap between universal joint assembly and the universal-joint fork.The utility model is simple in structure, be easy to manufacturing, on the basis that does not influence whole transmission shaft performance, carried out bigger improvement, and weight saving also greatly reduces manufacture cost, and market potential is big, is worthy of popularization.
Description of drawings
Fig. 1 is the structural representation of traditional minicar transmission shaft;
Fig. 2 is the structural representation of the utility model.
Embodiment
As shown in Figure 2; A kind of minicar transmission shaft of the utility model; Comprise from an end connecting flange york 1, universal joint assembly 2, universal-joint fork 3, central siphon 4, universal-joint fork 10, universal joint assembly 7 and the slip yoke 6 of setting successively, outside slip yoke 6, be arranged with dust-proof cover 9 to the other end.Flange york 1 is connected by bolt with the minicar back axle, and slip yoke 6 is connected with external splines on the minicar gearbox.Be provided with jump ring 11 between universal joint assembly 2 and the universal-joint fork 3, jump ring 11 is used for regulating the gap between universal joint assembly 2 and the universal-joint fork 3.Establish jump ring 12 between universal-joint fork 10 and the universal joint assembly 7, jump ring 12 is used for regulating the gap between universal joint assembly 7 and the universal-joint fork 10.
The utility model is different with traditional transmission shaft structure, no longer continues to use the structure type that two ends all are flange yorks, and designing an end is that flange york 1, one end is a slip yoke 6.Under performance satisfies usage requirement, compare comparison diagram 1 and Fig. 2 with traditional transmission shaft; The utility model saves a flange york 8 and increases a universal-joint fork 10; Saved a splined shaft 5, like this, whole automobile chassis connects just can save a cost than higher part; For car load is practiced thrift cost, and make driving-shaft assembly loss of weight 10%.
Claims (2)
1. minicar transmission shaft is characterized in that: comprise from an end connecting flange york, universal joint assembly, universal-joint fork, central siphon, universal-joint fork, universal joint assembly and the slip yoke of setting successively to the other end, outside slip yoke, be arranged with dust-proof cover.
2. a kind of minicar transmission shaft according to claim 1 is characterized in that: be provided with jump ring between said universal joint assembly and the universal-joint fork.
