Abstract
The utility model relates to a cardan joint half shaft in an automobile steering drive axle. The cardan joint half shaft in the automobile steering drive axle aims to lower the weight and save materials under the condition that a half shaft torque is not changed. The cardan joint half shaft in the automobile steering drive axle comprises an outer half shaft and an inner half shaft, one end of the outer half shaft is connected with a cardan joint through a joint fork, and the other end of the outer half shaft is in key connection with a hub reduction gear. One end of the inner half shaft is connected with the cardan joint through the joint fork, and the other end of the inner half shaft is in key connection with a main speed reducer. The cardan joint half shaft in the automobile steering drive axle is characterized in that a hollow shaft is arranged in the middle of the outer half shaft or the middle of the inner half shaft, and the two ends of the hollow shaft are connected with the joint fork and a solid spline shaft respectively through friction welding. Preferably, hollow shafts are arranged both in the outer half shaft and the inner half shaft.
Description
Technical field
The utility model relates to a kind of semi-axis structure, particularly the articulated shaft on a kind of motor turning ransaxle.
Background technique
At present, double cardan universal joint semiaxis is applied in car load is turned in the steering drive axle of having relatively high expectations, and the domestic inside and outside semiaxis of double cardan universal joint axle is generally the solid shaft that solid forging forms, complex process, and waste of material is more, and manufacture cost is high.
Model utility content
For deficiency of the prior art, the utility model aims to provide a kind of in the situation that not changing semiaxis moment of torsion, weight reduction, the articulated shaft in the motor turning ransaxle of saving material.
In order to address the above problem, the articulated shaft in this kind of motor turning ransaxle, comprising: outer semiaxis and inner shaft, and outer semiaxis one end is pitched with universal joint and is connected by joint, and the other end is connected with wheel reductor key; Inner shaft one end is pitched with universal joint and is connected by joint, and the other end is connected with main reducing gear key, it is characterized in that: the middle part of this outer semiaxis or inner shaft is hollow shaft, and these hollow shaft two ends weld together by friction welding with joint fork and solid splined shaft respectively.
Preferably, the middle part of described outer semiaxis and inner shaft is hollow shaft.
The beneficial effects of the utility model are: this kind of articulated shaft, by selecting tubing manufacture, not only can effectively reduce weight, cost-saving, improve the working life of double cardan universal joint axle.The inside and outside semiaxis that adopts split to forge can not only effectively improve the utilization ratio of material, and the manufacturing process of inside and outside semiaxis is simplified, by changing the length of semiaxis, just can change the length of inside and outside semiaxis, the product manufacturing cycle shortens, and reduces the expense producing because of mold developing.
Accompanying drawing explanation
Fig. 1 is the sectional structure schematic diagram of the articulated shaft in motor turning ransaxle of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in Figure 1, articulated shaft in this kind of motor turning ransaxle, comprising: outer semiaxis 1 and inner shaft 3, and the middle part of this outer semiaxis 1 or inner shaft 3 is hollow shaft, weld by friction welding with joint fork one end of this hollow shaft, and the other end and one section of solid splined shaft weld by friction welding.Here, wherein a semiaxis has above-mentioned hollow-core construction, and another root semiaxis can be traditional solid shaft, can be also the semiaxis similar to said structure, and the middle part of semiaxis 1 and inner shaft 3 is hollow shaft.
The inside and outside semiaxis of this kind of double cardan universal joint axle forges by split, inside and outside semiaxis is divided into one or more snippets to be re-used friction welding after forging molding respectively and is welded as integral body, simultaneously, half shaft portion can adopt solid construction, also can adopt hollow-core construction, when using hollow-core construction, can select tubing manufacture, not only can effectively reduce weight, cost-saving, the working life of improving double cardan universal joint axle.The inside and outside semiaxis that adopts split to forge can not only effectively improve the utilization ratio of material, and the manufacturing process of inside and outside semiaxis is simplified, by changing the length of semiaxis, just can change the length of inside and outside semiaxis, the product manufacturing cycle shortens, and reduces the expense producing because of mold developing.
