Abstract
The invention relates to a light-weight hub shell of a car transmission connector. The light-weight hub shell comprises a hub and a cavity, wherein three first circular-arc sections are arranged on the inner cavity of the cavity; adjacent two first circular-arc sections form a circular-arc ball path at the inner cavity of the cavity; three groove sections are arranged on the outer wall of the cavity; the groove sections are symmetrically arranged with respect to the circular-arc ball path; the hub is formed by three lug boss sections; and adjacent two lug boss sections are transited through a second circular arc. The light-weight hub shell has the advantages that: the lug boss sections form the hub on the cavity, the adjacent two lug boss sections are transited through the second circular arc, the first circular-arc sections are arranged in the inner side wall of the cavity, adjacent two first circular-arc sections form the circular-arc ball path, and the grooves are arranged on the outer side wall of the cavity; compared with a current structure, the integral product weight is reduced by 30% relative to the current product weight; moreover, light-weight volume distribution of materials is reasonably carried out according to mechanical requirements of the product, so that the performance of the product is improved, the quality of the product is guaranteed, the raw material loss is reduced, and the mould processing period is shortened.
Description
Technical field
The present invention relates to a kind of lightweight hub shell of car transmission coupling piece.
Background technique
Along with science and technology constantly develops, living standard improves constantly, the continuous enhancing of environmental consciousness, and people are also just more and more higher to the performance of car and safety requirement.Car Drive Shaft as safety knot component most important in car transmission component, because of many excellent in performance such as its claimed structure is compact, lightweight, low noise, reliability are high, freedom from repairs.So cause its complex structure, produce, processing, detection difficulty is all very large, the transmission system of the whole world car overwhelming majority all adopts sliding end housing as the power transmission component from gearbox to wheel of key, because of the operating characteristic of its product, so require very high to concentricity between each structure of semi-cylindrical arc surface cylindricality alley inner chamber of the even circumferential of three in this product distribution and alley indexing accuracy, existing Car Drive Shaft sliding end flange shell comprises wheel hub and cavity, the inner chamber of described cavity is evenly distributed in endoporus by six semi-cylindrical arc surface cyclotomy deciles Saturday, six cylindricality alleys are formed in endoporus, the outer wall cylindrical structural of described cavity, described wheel hub is made up of 1 circular discs and 6 cylindrical holes, and its cavity profile and wheel hub profile are all cylindrical structural, and structure is simple, and consumptive material is many, and utilization rate of raw materials is very low, and cost of production is high.Inner-cavity structure amount of deformation in follow-up heat treatment process of six semi-cylindrical arc surfaces is very large, is difficult to the precision ensureing product.Simultaneously because much unnecessary materials considerably increase the weight of product on product, cause in car using process afterwards occur that oil consumption is many, noise is high, travel in tremble and large etc. affect performance and safe many hidden danger.
Summary of the invention
The technical problem to be solved in the present invention is just to provide a kind of lightweight hub shell of car transmission coupling piece, effectively can solve existing flange shell and there is processing difficulties and the high problem of cost of production.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of lightweight hub shell of car transmission coupling piece, comprise wheel hub and cavity, cavity is arranged on wheel hub, the inner chamber of cavity is provided with the first circular arc of three sections of rectangular shapes settings of cross section, three section of first circular arc is that trisection is evenly distributed on cavity circumferentially, adjacent two section of first circular arc forms the rectangular circular arc alley of one section of cross section at the inner chamber of cavity, the outer wall of cavity is provided with the groove that three sections of cross sections are circular arc, groove and circular arc alley are symmetrical arranged, wheel hub is formed by the boss that three sections are arranged on cavity, excessive by the second circular arc between adjacent both ends boss, every section of boss is evenly provided with two fixed holes.
Preferably, the settings such as the cavity wall thickness homogeneous phase at three section of first circular arc place, ensure that product comprehensive mechanical property, turn avoid the thermal distortion in subsequent heat treatment course of working, namely improve product size precision and integrated quality.
Preferably, the diameter of groove equals the diameter of the second circular arc, and overall processing effect is good, connects reliable.
Preferably, wheel hub and cavity are made into integration, and the height of boss equals the diameter of fixed hole, is wholely set easy to process, connect reliable, improve the join strength of wheel hub, prevent the damage of wheel hub.
In sum, advantage of the present invention: form wheel hub by three sections of boss on cavity, adjacent two sections of boss also pass through the second arc transition, the circular arc alley that the first circular arc that inside cavities wall is provided with and adjacent two section of first circular arc are formed, the groove that cavity outer side wall is provided with, relative to existing structure, overall product weight reduces 30% than existing product weight, and the lightweight capacity distribution of material rationally can be carried out according to the mechanical requirements of product, namely improve the performance of product, in turn ensure that the quality of product, reduce raw material loss simultaneously, shorten the Mould Machining cycle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is the structural representation of the lightweight hub shell of a kind of car transmission of the present invention coupling piece;
