Abstract
The present invention discloses a kind of end cap of racing car differential mechanism, racing car differential mechanism comprises upper end portion, middle part, underpart, upper end portion comprises from top to bottom and has diameter D1 respectively, first cylindrical body of D2, second cylindrical body, middle part is the three cylindrical body with diameter D3, D1<D2<D3, the two ends up and down of three cylindrical body have chamfering, the sidewall of three cylindrical body has three grooves of even circumferential distribution, the cross section of groove is radius r and action h fan-shaped, end cap comprises Upper shaft sleeve and Lower shaft sleeve, on, the internal diameter of Lower shaft sleeve is D4 respectively, D3, D4=D2=D3-2r+2h, the inwall of Lower shaft sleeve has the convex of fitting with three grooves, the cross section of convex is radius r and action h fan-shaped, the close outer edge of the end face of Lower shaft sleeve is drilled with multiple bolt connecting hole.
Description
Technical field
The present invention relates to the technical field of racing car, particularly relate to a kind of end cap of racing car differential mechanism.
Background technique
The differential mechanism that racing car adopts is the irregular body (as Figure 1-3) small in ends broad in the middle that overall length is only the cylindrical body composition of multiple different-diameters of 200mm, the differential mechanism face be connected with other parts by bolt is the widest only has the width of 9mm to be plane and remaining is the inclined-plane of 40 degree towards camber angle for 19mm, the face of such feature accounts for 1/2nd of all junction surfaces, and in the other junction surface of 1/2nd, the narrowest junction surface only has the width of 9mm and wall thickness is only 3mm.The plane wide and very thin at differential mechanism 9mm is bored evenly distributedly bolt connecting hole to reduce the intensity of differential mechanism to a certain extent and there is the danger of leakage of oil.
Summary of the invention
For overcoming the defect of prior art, the technical problem to be solved in the present invention there is provided a kind of bolt hole can be replaced to play connection function and do not affect differential mechanism intensity, avoid that leakage of oil is dangerous, transmission of torque steadily, be connected reliably with differential mechanism, install and remove and facilitate and the end cap of racing car differential mechanism without axial float.
Technological scheme of the present invention is: the end cap of this racing car differential mechanism, racing car differential mechanism comprises upper end portion, middle part, underpart, upper end portion comprises from top to bottom and has diameter D1 respectively, first cylindrical body of D2, second cylindrical body, middle part is the three cylindrical body with diameter D3, D1<D2<D3, the two ends up and down of three cylindrical body have chamfering, the sidewall of three cylindrical body has three grooves of even circumferential distribution, the cross section of groove is radius r and action h fan-shaped, end cap comprises Upper shaft sleeve and Lower shaft sleeve, on, the internal diameter of Lower shaft sleeve is D4 respectively, D3, D4=D2=D3-2r+2h, the inwall of Lower shaft sleeve has the convex of fitting with three grooves, the cross section of convex is radius r and action h fan-shaped, the close outer edge of the end face of Lower shaft sleeve is drilled with multiple bolt connecting hole.
Because the second cylindrical body of the Upper shaft sleeve of end cap and the upper end portion of racing car differential mechanism is fitted and groove in the middle part of the Lower shaft sleeve of end cap and racing car differential mechanism is fitted, serve effect that differential mechanism is connected with other parts so this end cap substitutes the bolt hole spudded on differential mechanism and do not affect differential mechanism intensity, avoid leakage of oil danger, and transmission of torque steadily, be connected reliably with differential mechanism, install and remove and to facilitate and without axial float.

Embodiment
As Figure 1-5, the end cap of this racing car differential mechanism, racing car differential mechanism 1 comprises upper end portion, middle part, underpart, upper end portion comprises from top to bottom and has diameter D1 respectively, first cylindrical body 11 of D2, second cylindrical body 12, middle part is the three cylindrical body 13 with diameter D3, D1<D2<D3, the two ends up and down of three cylindrical body have chamfering 131, the sidewall of three cylindrical body has three grooves 132 of even circumferential distribution, the cross section of groove is radius r and action h fan-shaped, end cap 2 comprises Upper shaft sleeve 21 and Lower shaft sleeve 22, on, the internal diameter of Lower shaft sleeve is D4 respectively, D3, D4=D2=D3-2r+2h, the inwall of Lower shaft sleeve has the convex 221 of fitting with three grooves, the cross section of convex is radius r and action h fan-shaped, the close outer edge of the end face 223 of Lower shaft sleeve is drilled with multiple bolt connecting hole 222.
Because the second cylindrical body of the Upper shaft sleeve of end cap and the upper end portion of racing car differential mechanism is fitted and groove in the middle part of the Lower shaft sleeve of end cap and racing car differential mechanism is fitted, serve effect that differential mechanism is connected with other parts so this end cap substitutes the bolt hole spudded on differential mechanism and do not affect differential mechanism intensity, avoid leakage of oil danger, and transmission of torque steadily, be connected reliably with differential mechanism, install and remove and to facilitate and without axial float.
Preferably, bolt connecting hole 222 even circumferential distribution.
Preferably, bolt connecting hole 222 and M6 bolt are connected.
Preferably, r=50mm, the laminating tolerance of convex 221 and groove 132 is 0.04mm.
The above; it is only preferred embodiment of the present invention; not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong to the protection domain of technical solution of the present invention.
