Specific embodiment
It is illustrated below in conjunction with preferred embodiment of the attached drawing to the utility model, it should be understood that described herein excellent
It selects embodiment to be only used for describing and explaining the present invention, is not used to limit the utility model.
Embodiment: as shown in Figs. 1-5, the utility model provides a kind of technical solution, a kind of automobile drive bridge speed differientiator shell,
Including upper housing 1, lower case 2 is installed below upper housing 1, connects between upper housing 1 and lower case 2 by the way that fixed screw is fixed
It connects, 1 top of upper housing offers the first output shaft hole 3, and lubrication assembly 4, lubrication assembly 4 are equipped on the outside of the first output shaft hole 3
Including grease-box 401, fuel feed hole 402, sealing cover 403, oil suction sponge 404 and oil seepage hole 405, upper housing 1 and grease-box
By being welded to connect between 401,401 top side of grease-box offers fuel feed hole 402, and 402 top of fuel feed hole passes through screw thread
It is fixedly installed with sealing cover 403,401 inner sidewall of grease-box is fitted with oil suction sponge 404, in order to enable in grease-box 401
What is be fixedly connected between wall and oil suction sponge 404 is more stable, passes through limit between 401 inner wall of grease-box and oil suction sponge 404
Position is connected together, and 401 inside of grease-box is equidistant to offer oil seepage hole 405.
In order to radiate to the heat for rubbing and generating between differential mechanism internal gear, while in differential carrier
The temperature in portion radiates, and extends the service life of differential mechanism and differential carrier, 1 top of upper housing is equidistant to offer heat release hole
5, on the outside of upper housing 1 by weld it is equidistant first heat sink 6 is installed, 6 middle part of the first heat sink is by being installed by welding with the
Two heat sinks 7.
In order to can be by the engaging between limit card block 13 and limit card slot 11, to first flange disk 8 and second flange
Torsional forces between disk 12 is shared, and avoids torsional forces excessive, causes to connect consolidating for first flange disk 8 and second flange disk 12
Determine screw to wear, differential carrier caused loose phenomenon occur, 1 bottom end of upper housing by being installed by welding with first flange disk 8,
Offer differential chamber 9 inside upper housing 1,1 one middle side part of upper housing offers input shaft bore 10, in 8 bottom end of first flange disk
Portion offers limit card slot 11, and 2 top of lower case is by being installed by welding with second flange disk 12,12 upper surface pair of second flange disk
Answer 11 position of limit card slot by being installed by welding with limit card block 13, in order to enable blocking between limit card block 13 and limit card slot 11
