Abstract
The utility model discloses a middle axle output shaft. The middle axle output shaft comprises an axle body and a flange plate, wherein the flange plate is arranged on one end of the axle body; a groove is formed in the middle part on the end surface of the flange plate; the groove is sunken into the axle hole; the groove is distributed in the axial direction in the form of a variable cross section; the section area at the port of the groove is maximal; the section area at the bottom of the groove is minimal; the bottom of the groove and the port are smoothly transitional; two notches are formed in the edge of the flange plate and are symmetrical. The middle axle output shaft has beneficial effects of reducing the weight of the whole middle axle output shaft while ensuring the structural strength of the middle axle output shaft, and reducing the product material cost.
Description
Technical field
The utility model relates to a kind of middle bridge of heavy duty automobile, relates in particular to a kind of jackshaft output shaft.
Background technology
The structure of the jackshaft output shaft on the existing heavy motor vehicle consists of (axis body and flange are integral structure) by axis body and flange, wherein, flange is the circular flange of rule, the junction of axis body and flange is the solid construction body, such structure causes the deadweight of jackshaft output shaft very large, and have redundancy on the structure, the material cost of making product is higher.
The utility model content
For the problem of background technology, the utility model proposes a kind of jackshaft output shaft, comprise axis body and flange, described flange is arranged at an end of axis body, and its improvement is: the middle part of flange end face is provided with groove, and groove gos deep in the axis body.After adopting aforementioned structure, can effectively reduce the deadweight of jackshaft output shaft, reduce material cost.
On the basis of aforementioned improved, for the effect that makes groove reduce deadweight reaches maximization, the utility model has also been done following improvement: described groove is in the axial direction variable section and distributes, the sectional area of groove port is maximum, the sectional area at groove bottom land place is minimum, seamlessly transits between bottom land and the port.
On the basis of aforementioned improved, in order further to reduce deadweight, the utility model has also been done following improvement: the flange edge is provided with breach.
Based on the aforementioned improvement that breach is set, the utility model has also been done following improvement: the quantity of described breach is two, two gap position symmetries.
Useful technique effect of the present utility model is: under the condition of the structural strength that guarantees the jackshaft output shaft, make the weight of whole jackshaft output shaft obtain alleviating, reduced product material cost.
Description of drawings
Fig. 1 is schematic diagram of the present utility model;
Fig. 2 is schematic diagram of the present utility model;
Fig. 3 is the schematic diagram of prior art;
Fig. 4 is the schematic diagram of prior art;
Among the figure: axis body 1, flange 2, groove 3, breach 4.
The specific embodiment
For existing jackshaft output shaft, our technical personnel adopts virtual technology that its mechanical structure is conducted in-depth analysis, the analysis conclusion shows, during running car, the suffered stress in axis body 1 middle part is maximum, the stress that axis body 1 end and flange 2 places are subjected to is very little, thereby so that have structural redundancy on the existing jackshaft output shaft, therefore, the contriver considers from eliminating the angle of structural redundancy, the deadweight of jackshaft output shaft is alleviated, reduce simultaneously the material consumption when producing, concrete scheme is:
A kind of jackshaft output shaft comprises axis body 1 and flange 2, and described flange 2 is arranged at an end of axis body 1, and its improvement is: the middle part of flange 2 end faces is provided with groove 3, and groove 3 gos deep in the axis body 1.Prove through experimental analysis, the required stress of bearing of the structure at flange 2 and axis body 1 junction and peripheral position place is very little, cause original solid section of groove 3 positions to become redundancy structure, even with its elimination, can not affect structural strength yet, also so that the deadweight of jackshaft output shaft has obtained reduction, reduced material consumption simultaneously.
Based on aforesaid scheme, the utility model has also been done following improvement: described groove 3 is in the axial direction variable section and distributes, and the sectional area of groove 3 ports is maximum, and the sectional area at groove 3 bottom land places is minimum, seamlessly transits between bottom land and the port.
In order further to reduce dead load, the utility model has also carried out following improvement for flange 2: flange 2 edges are provided with breach 4.
Based on aforementioned improvement for flange 2, the utility model has also proposed following preferred version: the quantity of described breach 4 is two, and two breach 4 positions are symmetrical.
