Description
Technical field
This utility model relates to the lightweight hub shell of a kind of car transmission connector.
Background technology
Along with science and technology constantly develops, living standard improves constantly, and the continuous enhancing of environmental consciousness, people are also just more and more higher with safety requirements to the performance of car. Car Drive Shaft is as safeguard construction part most important in car transmission parts, because it requires many excellent in performance such as compact conformation, lightweight, low noise, reliability height, freedom from repairs. so causing its structure complicated, produce, processing, detection difficulty is all very big, the drive system of the whole world car overwhelming majority all adopts sliding end housing as the crucial power transmission component from change speed gear box to wheel, operating characteristic because of its product, so concentricity and alley indexing accuracy between the semi-cylindrical arc surface cylindricality each structure of alley inner chamber of three even circumferential distributions in this product are required very high, existing Car Drive Shaft sliding end flange shell includes wheel hub and cavity, the inner chamber of described cavity is evenly distributed in endoporus by six semi-cylindrical arc surface cyclotomy deciles Saturday, endoporus is formed six cylindricality alleys, 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, simple in construction, and consumptive material is many, and utilization rate of raw materials is very low, and production cost is high. the inner-cavity structure of six semi-cylindrical arc surfaces deflection in follow-up heat treatment process is very big, it is difficult to ensure the precision of product. simultaneously as materials much unnecessary on product considerably increase the weight of product, cause car use procedure afterwards occurs oil consumption is many, noise is high, travel in tremble and big etc. affect performance and safe many hidden danger.
Utility model content
The technical problems to be solved in the utility model is just to provide the lightweight hub shell of a kind of car transmission connector, can effectively solve existing flange shell and there is processing difficulties and the high problem of production cost.
In order to solve above-mentioned technical problem, this utility model is achieved through the following technical solutions: the lightweight hub shell of a kind of car transmission connector, including wheel hub and cavity, cavity is arranged on wheel hub, the inner chamber of cavity is provided with the first circular arc that three sections of rectangular shapes of cross section are arranged, three section of first circular arc is that trisection is evenly distributed on the circumference of cavity, adjacent two section of first circular arc forms, at the inner chamber of cavity, the circular arc alley that one section of cross section is rectangular, 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 three sections of boss being arranged on cavity, the second circular arc is passed through excessive between adjacent both ends boss, every section of boss is uniformly provided with two fixing holes.
Preferably, arrange at the cavity wall thickness homogeneous phase at three section of first circular arc place etc., it is ensured that product comprehensive mechanical property, turn avoid the thermal deformation in the subsequent heat treatment course of processing, namely improve product size precision and integrated quality.
Preferably, the diameter of groove is equal to 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, equal to the diameter of fixing hole, is wholely set easy to process, connect reliable, improve the bonding strength of wheel hub, it is prevented that the damage of wheel hub.
In sum, advantage of the present utility model: form wheel hub on cavity by three sections of boss, adjacent two sections of boss also pass through the second arc transition, the first circular arc that inside cavities wall is provided with and the circular arc alley that adjacent two section of first circular arc is formed, the groove that cavity lateral wall is provided with, relative to existing structure, overall product weight reduces 30% than existing product weight, and the lightweight capacity distribution of material can be rationally 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 process-cycle.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the structural representation of the lightweight hub shell of a kind of car transmission connector of this utility model;
Fig. 2 is the sectional view of the A-A of Fig. 1.
Detailed description of the invention
Such as Fig. 1, shown in Fig. 2, a kind of lightweight hub shell of car transmission connector, including wheel hub 1 and cavity 2, cavity 2 is arranged on wheel hub 1, the inner chamber of cavity 2 is provided with the first circular arc 3 that three sections of rectangular shapes of cross section are arranged, three section of first circular arc 3 is evenly distributed on the circumference of cavity 2 in trisection, adjacent two section of first circular arc 3 forms, at the inner chamber of cavity 2, the circular arc alley 4 that one section of cross section is rectangular, the outer wall of cavity 2 is provided with the groove 5 that three sections of cross sections are circular arc, groove 5 and circular arc alley 4 are symmetrical arranged, wheel hub 1 is formed by three sections of boss being arranged on cavity 26, the second circular arc 7 is passed through excessive between adjacent both ends boss 6, every section of boss 6 is uniformly provided with two fixing holes 8, the cavity 2 equal setting of uniform wall thickness at three section of first circular arc 3 place, ensure that product comprehensive mechanical property, turn avoid the thermal deformation in the subsequent heat treatment course of processing, namely improve product size precision and integrated quality, the diameter of groove 5 is equal to the diameter of the second circular arc 7, overall processing effect is good, connect reliable, wheel hub 1 and cavity 2 are made into integration, the height of boss 6 is equal to the diameter of fixing hole 8, it is wholely set easy to process, connect reliable, improve the bonding strength of wheel hub, prevent the damage of wheel hub.
