Description
Technical field
The invention belongs to power transmission shaft technical field, more particularly to a kind of few part lightweight power transmission shaft.
Background technology
Current light truck class power transmission shaft uses segmentation structure, and rear and front end power transmission shaft is coordinated using convex and recessed seam, used
Bolt, the mode of nut fastening is 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, 14 annexes altogether.Middle part number of components
Mesh is more, heavier-weight.Error is also larger caused by different part form and position tolerances coordinate, and middle four nuts need to connect tight
Gu, manufacturing process inefficiency.Meanwhile, number of parts is more with matching relationship, and quality risk point is also more, power transmission shaft reliability
It is relatively low.
The content of the invention
It is an object of the invention to overcome the shortcomings of that prior art is present, and provide a kind of fit precision height, good reliability
Few part lightweight power transmission shaft.
The purpose of the present invention is completed by following technical solution, including front propeller shaft, inter-axle shaft, it is described before
One end of power transmission shaft is welded with the second splined shaft, and the other end of inter-axle shaft is welded with weld yoke, second splined shaft and welding
In positioned opposite between fork；Slip yoke is provided with described weld yoke, the second splined shaft is inserted in the slip yoke；Described
Positioning sleeve and jump ring are installed on two splined shafts, the positioning sleeve fixes the bearing on the second splined shaft, and pass through jump ring card
Tight spacing fixation, 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.
Beneficial effects of the present invention are：New construction power transmission shaft light truck number of parts is reduced, weight saving 2.3kg；Power transmission shaft
After part is reduced, the production cost reduction of each operation, production efficiency improves about more than 50%；Simultaneously it can be reduced for automobile
Oil consumption, reaches the purpose of energy-saving and emission-reduction；By the structure for changing middle spline shaft so that middle spline shaft possesses to be propped up in the middle of installation
The function that support coordinates with free-sliding spline；Improve the fit precision of power transmission shaft again while number of parts is reduced, improve transmission
The reliability of axle.

Embodiment
Detailed introduction is done to the present invention below in conjunction with accompanying drawing：As shown in accompanying drawing 2,3, the present invention includes front propeller shaft
11st, inter-axle shaft 12, one end of described front propeller shaft 11 is welded with the second splined shaft 13, the other end welding of inter-axle shaft 12
There is weld yoke 14, in positioned opposite between second splined shaft 13 and weld yoke 14；Slip yoke is provided with described weld yoke 14
15, the second splined shaft 13 is inserted in the slip yoke 15；Positioning sleeve 16 and jump ring 17 are installed on the second described splined shaft 13,
The positioning sleeve 16 fixes the bearing 18 on the second splined shaft 13, and by the spacing fixation of the clamping of jump ring 17, and the positioning sleeve 6
It is located at the side of slip yoke 15 with jump ring 17.
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 6
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, 1 annex altogether.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 be changed to the structure of positioning sleeve 16 and jump ring 17, reduce by a major part again herein.Pitched again because eliminating flange 2,
Therefore, front and rear two sections power transmission shaft is no longer needed by bolt 9, and nut 8 is attached.12 annexes are reduced herein.
It is understood that it will be understood by those skilled in the art that being subject to technical scheme and inventive concept
It should all belong to the protection domain of appended claims of the invention with replacing or changing.
