Abstract
The invention discloses an end cover of a differential mechanism of a racing automobile. The differential mechanism of the racing automobile comprises an upper end portion, a middle portion and a lower end portion. The upper end portion comprises a first cylinder with the diameter as D1and a second cylinder with the diameter as D2 from the top to the bottom, and the middle portion is provided with a third cylinder with the diameter as D3, wherein D1<D2<D3. Chamfers are arranged at the upper end and the lower end of the third cylinder, and three through grooves distributed evenly are arranged on a lateral wall of the third cylinder. The cross section of each through groove is a sector with the radius as r and chord height as h. The end cover comprises an upper shaft sleeve and a lower shaft sleeve, the inner diameters of the upper shaft sleeve and the lower shaft sleeve are respectively D4 and D3, wherein D4=D2=D3-2r+2h. Bosses attached to the three through grooves are arranged on an inner wall of the lower shaft sleeve, the cross section of each boss is a sector with the radius as r and chord height as h, and a plurality of bolt connecting holes are arranged at the position of an end face of the lower shaft sleeve close to an outer edge.
Description
Technical field
The present invention relates to the technical field of racing car, relate in particular to a kind of end cap of racing car differential mechanism.
Background technique
The differential mechanism that racing car is adopted is the irregular body (as Figure 1-3) small in ends broad in the middle that overall length only forms for the cylindrical body of a plurality of different-diameters of 200mm, the differential mechanism face that is connected with other parts by bolt the widest for 19mm and only have the width of 9mm be the plane remaining be to be the inclined-planes of 40 degree towards camber angle, the face of feature accounts for 1/2nd of all junction surfaces like this, and the narrowest junction surface only has the width of 9mm and wall thickness only to be 3mm in other 1/2nd the junction surface.Bore evenly distributedly the danger that bolt connecting hole can reduce to a certain extent the intensity of differential mechanism and have leakage of oil at differential mechanism 9mm on the wide and very thin plane.
Summary of the invention
For overcoming the defective of prior art, the technical problem to be solved in the present invention provided a kind of can replace bolt hole 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 make things convenient for and the end cap of shaftless racing car differential mechanism to play.
Technological scheme of the present invention is: the end cap of this racing car differential mechanism, the racing car differential mechanism comprises the upper end portion, the middle part, the underpart, the upper end portion comprises having respectively diameter D1 from top to bottom, the first cylindrical body of D2, the second cylindrical body, the middle part is the three cylindrical body with diameter D3, D1＜D2＜D3, the up and down two ends of three cylindrical body have chamfering, sidewall at the three cylindrical body has three grooves that even circumferential distributes, the cross section of groove is the fan-shaped of radius r and action h, end cap comprises Upper shaft sleeve and Lower shaft sleeve, on, the internal diameter of Lower shaft sleeve is respectively D4, D3, D4=D2=D3-2r+2h, the inwall of Lower shaft sleeve has the convex of fitting with three grooves, and the cross section of convex is the fan-shaped of radius r and action h, and the close outer edge of the end face of Lower shaft sleeve is drilled with a plurality of bolt connecting holes.
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 the groove at the Lower shaft sleeve of end cap and racing car differential mechanism middle part is fitted, so this end cap substitutes the bolt hole that spuds at differential mechanism and has played the effect that differential mechanism is connected with other parts and do not affected differential mechanism intensity, avoided leakage of oil dangerous, and transmission of torque steadily, be connected reliably with differential mechanism, install and remove and make things convenient for and shaftless to play.

Embodiment
Shown in Fig. 1-5, the end cap of this racing car differential mechanism, racing car differential mechanism 1 comprises the upper end portion, the middle part, the underpart, the upper end portion comprises having respectively diameter D1 from top to bottom, the first cylindrical body 11 of D2, the second cylindrical body 12, the middle part is the three cylindrical body 13 with diameter D3, D1＜D2＜D3, the up and down two ends of three cylindrical body have chamfering 131, sidewall at the three cylindrical body has three grooves 132 that even circumferential distributes, the cross section of groove is the fan-shaped of radius r and action h, end cap 2 comprises Upper shaft sleeve 21 and Lower shaft sleeve 22, on, the internal diameter of Lower shaft sleeve is respectively D4, D3, D4=D2=D3-2r+2h, the inwall of Lower shaft sleeve have the convex 221 of fitting with three grooves, the cross section of convex is the fan-shaped of radius r and action h, and the close outer edge of the end face 223 of Lower shaft sleeve is drilled with a plurality of bolt connecting holes 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 the groove at the Lower shaft sleeve of end cap and racing car differential mechanism middle part is fitted, so this end cap substitutes the bolt hole that spuds at differential mechanism and has played the effect that differential mechanism is connected with other parts and do not affected differential mechanism intensity, avoided leakage of oil dangerous, and transmission of torque steadily, be connected reliably with differential mechanism, install and remove and make things convenient for and shaftless to play.
Preferably, bolt connecting hole 222 even circumferentials distribute.
Preferably, bolt connecting hole 222 is connected with the M6 bolt.
Preferably, r=50mm, the applying tolerance of convex 221 and groove 132 is 0.04mm.
The above; it only is preferred embodiment of the present invention; be not that the present invention is done any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment all still belong to the protection domain of technical solution of the present invention.
