Abstract
The present invention discloses a transmission shaft comprising a shaft body (1) and a spline body, the shaft body (1) is in turn provided with a first installation spline body (2), a first bearing neck (3), a first mounting ring (4), a shaft sleeve (5), a second bearing neck (6), a second installation spline body (7), a second mounting ring (8), a third bearing neck (9), a connection shaft (10) and a connection boss (11), the diameter of the first mounting ring (4) and the diameter of the shaft sleeve (5) are same, and the diameter of the second bearing neck (6), the diameter of the second installation spline body (7), the diameter of the second mounting ring (8), the diameter of the third bearing neck (9), the diameter of the connection shaft (10) and the diameter of connection boss (11) gradually decrease, the shaft sleeve (5) sleeves the shaft body (1), and the transmission shaft has the advantage of being stable in structure and suitable for installation.
Description
Technical field
The present invention relates to power transmission shaft field, be specifically related to a kind of power transmission shaft being suitable to and installing。
Background technology
Power transmission shaft is the vitals transmitting power in automotive transmission, and its effect is, together with change speed gear box, drive axle, the power of electromotor is passed to wheel, makes automobile produce driving force。Existing power transmission shaft is unsuitable for installing, and it needs later maintenance more, adds artificial expenditure。
Summary of the invention
It is an object of the invention to provide one to be suitable to install and constitutionally stable power transmission shaft。
For solving the problems referred to above, the invention provides a kind of power transmission shaft, including axis body and spline body, described axis body is sequentially provided with the first installation spline body, clutch shaft bearing neck, the first installing ring, axle sleeve, the second bearing neck, the second installation spline body, the second installing ring, the 3rd bearing neck, connects axle and connect boss, the diameter of described first installing ring is identical with the diameter of axle sleeve, described second bearing neck, the second diameter installing spline body, the second installing ring, the 3rd bearing neck, connection axle and connection boss are sequentially reduced, and described axle sleeve is sheathed on axis body
The present invention compared with prior art, has the following advantages。
(1) the overall structure synergism of the present invention make the present invention have be suitable to install and constitutionally stable advantage。Owing to axis body being sequentially provided with the first installation spline body, clutch shaft bearing neck, the first installing ring, axle sleeve, the second bearing neck, the second installation spline body, the second installing ring, the 3rd bearing neck, connect axle and connect boss, reasonable in design, using Stability Analysis of Structures when installing, service life, relatively existing product was remarkably reinforced。Spline body and the second installation spline body mounting and connection parts are installed due to first, clutch shaft bearing neck and the second bearing neck are suitable with the bearing of parts, connecting spline body and connector suitable, axle sleeve is reasonable for the global design in service life extending axis body, it is ensured that result of use and increasing the service life。
(2) owing to the diameter of the first installing ring and the diameter of axle sleeve are identical; described second bearing neck, second install spline body, the second installing ring, the 3rd bearing neck, connect axle and connect boss diameter be sequentially reduced, reasonable in design; meeting the requirement of mate connection member, axle sleeve is sheathed on axis body and protects axis body comprehensively。Installing spline body due to first or the second installation spline surface layer is provided with protective layer, protective layer is zinc-plated protective layer, it is to avoid the desired physical considerations of parts does not reach use standard and can increase the service life, and reduces expenditure。
Accompanying drawing explanation
Fig. 1 is the structural representation of the power transmission shaft being suitable to install of the present invention。
In figure: 1-axis body, 2-first installs spline body, 3-clutch shaft bearing neck, 4-the first installing ring, 5-axle sleeve, 6-the second bearing neck, and 7-second installs spline body, 8-the second installing ring, 9-the 3rd bearing neck, and 10-connects axle, and 11-connects boss, 12-protective layer。
Detailed description of the invention
Below in conjunction with drawings and Examples the present invention will be further explained explanation
As shown in Figure 1, a kind of power transmission shaft, including axis body 1 and spline body, described axis body is sequentially provided with the first installation spline body 2, clutch shaft bearing neck the 3, first installing ring 4, axle sleeve the 5, second bearing neck the 6, second installation spline body the 7, second installing ring the 8, the 3rd bearing neck 9, connects axle 10 and connect boss 11, the diameter of described first installing ring 4 is identical with the diameter of axle sleeve 5, the diameter that described second bearing neck 6, second installs spline body the 7, second installing ring the 8, the 3rd bearing neck 9, connection axle 10 and connection boss 11 is sequentially reduced, and described axle sleeve 5 is sheathed on axis body 1。
Described first installation spline body 2 or the second installation spline body 7 top layer are provided with protective layer 12, and described protective layer 12 is zinc-plated protective layer。
Foregoing is example and the explanation of the present invention; but not meaning that the obtainable advantage of the present invention is so limited, wherein one or more of advantage being likely in the simple transformation to structure and/or some embodiments in every practice process of the present invention to realize are all in the protection domain of the application。
