Abstract
The utility model discloses a high performance planetary gear bracket of a motor vehicle, being provided with a bracket body and a gear shaft arranged on the bracket boy and being characterized in that the gear shaft (1) and the bracket body (2) are forged into a integral structure and three gear shafts are distributed evenly on the circumference surface of the bracket body. Because the planetary gear bracket of the utility mo el adopts a die forging method, the bracket and the three gear shafts are made into a integral structure and the planetary gear bracket has a compact structure in addition to displaying the characteristic of high performance. Therefore, with a good rigidity, the running is very stable. The three gear shafts being distributed evenly on the same circumference surface as requested ensures the position requirement corresponding to a bracket spline hole centre.
Description
[technical field]: the utility model relates to a kind of planetary gear carrier, particularly be a kind of Motor Vehicle high-performance planetary gear carrier.
[background technique] planetary gear carrier is one of strength member of vehicle transmission transmitting torque.At present, the domestic tower structure that generally adopts, the mounting hole of processing planet pin on framework.The processing mode of framework is also different, has plenty of the overall structure of grey cast iron casting; Has plenty of the composite structure that is welded with Ordinary Steel.No matter be that the sort of structure all seems and takes up space some heaviness.In addition, because support and gear shaft are splits, gear shaft is installed in the mounting hole of support, what adopt is that a kind of drive fit connects, and in the long-time using process of transmitting large torque, gear shaft will occur and get loose etc. and to influence the defective of rigidity, the stationarity of running is reduced, and noise increases.
In view of the existing problem of known technology, the technical problem that the utility model solved just provides a kind of compact structure, good rigidly, motor vehicle epicyclic gear plank stably turns round [summary of the invention].To achieve these goals, the utility model adopts following technological scheme to finish: this kind Motor Vehicle high-performance planetary gear carrier, have rack body and be arranged on gear shaft on the rack body, it is characterized in that described gear shaft and rack body forge into an overall structure, described gear shaft is three, evenly distributes on the rack body circumferential surface.Because the utility model planetary gear carrier has adopted the method for die forging, make support and three gear shafts become the overall structure of unification, make to have shown high performance characteristics again by the existing compact structure of planetary gear carrier, so it is rigidity is fine, very steady when so just making running.Article three, gear shaft is evenly distributed on the same circumference on request, has guaranteed the position degree requirement with respect to support splined hole center.
[description of drawings] the utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
[embodiment] accompanying drawing has been represented structure of the present invention and embodiment, further describes the relevant details of embodiment below more in conjunction with the accompanying drawings.This kind Motor Vehicle high-performance planetary gear carrier has rack body and puts gear shaft on rack body, and described gear shaft 1 and rack body 2 forge into an overall structure, and described gear shaft is three, evenly distributes on the rack body circumferential surface.Because planetary gear carrier is owing to adopt overall structure, adopted the Alloy Constructional Steel 42CrMo of better performances again, article three, gear shaft is evenly distributed on the same circumference, has so just guaranteed planetary gear carrier compact structure when mounted, and good rigidly during use, running are steadily, noise is little.The utility model compared with prior art has substantive distinguishing features and progress.
Claims (1)
1, a kind of Motor Vehicle high-performance planetary gear carrier, have rack body and be arranged on gear shaft on the rack body, it is characterized in that described gear shaft (1) and rack body (2) forge into an overall structure, described gear shaft is three, evenly distributes on the rack body circumferential surface.
