Description
Technical field
The utility model belongs to power transmission shaft technical field, more particularly to a kind of few part lightweight power transmission shaft.
Background technology
Light truck class power transmission shaft uses segmentation structure at present, and rear and front end power transmission shaft is coordinated using convex and concave mouth, is used
Bolt, the mode of nut fastening are attached.As shown in Figure 1, existing light truck class power transmission shaft is segmentation structure, pars intermedia
The part of position is the first splined shaft 1, flange yoke 2, flanged yoke 3, slip shaft yoke 4, spline housing 5, intermediate washer 6 and intermediate nut 7
And the nut 8 for connection, bolt 9,10 each 4, pad.5 major parts altogether, 14 annexes.Middle part number of components
Mesh is more, heavier-weight.Error caused by different part form and position tolerances coordinate is also larger, and middle four nuts need to connect tightly
Gu manufacturing process efficiency is low.Meanwhile number of parts and matching relationship are more, quality risk point is also more, power transmission shaft reliability
It is relatively low.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of the prior art, and it is high, reliable to provide a kind of fit precision
The good few part lightweight power transmission shaft of property.
The purpose of this utility model is completed by following technical solution, including front propeller shaft, inter-axle shaft, described
One end of front propeller shaft be welded with the second splined shaft, the other end of inter-axle shaft is welded with weld yoke, second splined shaft with
In positioned opposite between weld yoke；Slip yoke is provided with described weld yoke, the second splined shaft is inserted in the slip yoke；It is described
The second splined shaft on positioning sleeve and jump ring are installed, the positioning sleeve fixes the bearing on the second splined shaft, and passes through card
The spacing fixation of spring clamping, and the positioning sleeve and jump ring are located at slip yoke side.
Preferably, described jump ring is stuck in the groove opened up on the second splined shaft, the jump ring is located at by positioning sleeve.
Preferably, offering sliding groove in described slip yoke, the second splined shaft is coordinated by sliding groove and slip yoke
It is slidably connected.
The beneficial effects of the utility model are：New construction power transmission shaft light truck number of parts is reduced, weight saving 2.3kg；Pass
After moving axis part is reduced, the production cost of each operation reduces, and production efficiency improves about more than 50%；It can be dropped for automobile simultaneously
Its low oil consumption, reach the purpose of energy-saving and emission-reduction；By the structure for changing middle spline shaft so that middle spline shaft possesses in installation
Between support with free-sliding spline coordinate function；Improve the fit precision of power transmission shaft again while number of parts is reduced, improve
The reliability of power transmission shaft.

Embodiment
Detailed introduction is done to the utility model below in conjunction with accompanying drawing：As shown in accompanying drawing 2,3, before the utility model includes
Power transmission shaft 11, inter-axle shaft 12, one end of described front propeller shaft 11 are welded with the second splined shaft 13, inter-axle shaft 12 it is another
End is welded with weld yoke 14, in positioned opposite between second splined shaft 13 and weld yoke 14；It is provided with described weld yoke 14
Slip yoke 15, the second splined shaft 13 are inserted in the slip yoke 15；The He of positioning sleeve 16 is installed on the second described splined shaft 13
Jump ring 17, the positioning sleeve 16 fix the bearing 18 on the second splined shaft 13, and by the spacing fixation of the clamping of jump ring 17, and should
Positioning sleeve 16 and jump ring 17 are located at the side of slip yoke 15.
Described jump ring 17 is stuck in the groove 131 opened up on the second splined shaft 13, and the jump ring 17 is located at positioning sleeve 16
It is other；Sliding groove 151 is offered in described slip yoke 15, the second splined shaft 13 is coordinated by sliding groove 151 and slip yoke 15 to be slided
Dynamic connection.
Analysis optimization is carried out to intermediate structure, front and rear two section is carried out by the way of the second splined shaft 13 coordinates slip yoke 15
The fit system of power transmission shaft.The part of middle part is changed into the second splined shaft 13, positioning sleeve 16, jump ring 17, slip yoke after optimization
15, weld yoke 14.3 major parts altogether, 1 annex.Mutual structure before optimization than reducing 2 major parts, 13 annexes.Drop
While low number of parts, production efficiency is improved.Because of the reduction of number of parts, caused by corresponding part form and position tolerance with
Error also reduces, and the performance of power transmission shaft is relatively reliable.
First splined shaft 1 of traditional structure, slip shaft yoke 4, spline housing 5 are used the second splined shaft by new light truck power transmission shaft
13 substitute with slip yoke 15, reduce by a part herein, while the fixed form of bearing 18 is by flange yoke 2, nut 8, pad
10 mode is changed to the structure of positioning sleeve 16 and jump ring 17, reduces by a major part again herein.Again because eliminating flange 2
Fork, therefore, front and rear two sections power transmission shaft no longer need to be attached by bolt 9, nut 8.Reduce 12 annexes herein.
The utility model is not limited to above-mentioned embodiment, makees any change no matter being formed in its shape or material, all
It is to use structure design provided by the utility model, is all a kind of deformation of the present utility model, is considered as new in this practicality
Within type protection domain.
