Description
Technical field
The utility model relates to differential art field, is specifically related to a kind of piece differential cage body.
Background technique
Differential mechanism is assembled by differential casing, planetary pinion, differential gear, semiaxis and planet pin.Differential casing serves as planetary wheel carrier, and planetary pinion, differential gear, semiaxis and planet pin are arranged in differential casing.Differential casing adopts integrally casting shaping usually, inner chamber is provided with for holding planetary pinion and differential gear at the middle part of housing, two of housing is provided with half axis hole that communicates with inner chamber for installing semiaxis, housing is provided with the planetary gear shaft hole of lateral direction penetrating inner chamber for installing planet pin, the outer wall of housing horizontally outward extends to form spiral bevel gear setting circle for installing fixing spiral bevel gear.
The subject matter that existing structure exists is: (1) spiral bevel gear is fixed by screws in spiral bevel gear setting circle, for ensureing enough worm tooth numbers, needs the thickness increasing spiral bevel gear setting circle, cause differential casing always great, manufacture cost is high; (2) half shaft hole inner walls are provided with helical oil groove, must be added by machine and form, add one technique; (3) inner chamber is curved surface, and holding space is little, and the overall dimensions of differential casing is higher.
Model utility content
Of the present utility modelly aim to provide that a kind of volume is little, lightweight, cost is low, the differential casing of easily manufactured, compact structure.
For this reason, the technological scheme that the utility model adopts is: a kind of piece differential cage body, employing integrally casting is shaping, the middle part of described housing is provided with sphere inner chamber for holding planetary pinion and differential gear, two of housing is provided with half axis hole communicated with sphere inner chamber, housing is provided with the planetary gear shaft hole of lateral direction penetrating sphere inner chamber, the outer wall of housing horizontally outward extends to form spiral bevel gear setting circle, described housing is provided with the positioning pin hole of a longitudinal extension for locking the planet pin of planetary gear shaft hole, it is characterized in that: the side hoop of described spiral bevel gear setting circle is distributed with reinforcement platform, each reinforcement platform is provided with the gear fastener hole of a through spiral bevel gear setting circle of longitudinal direction, described half shaft hole inner wall is distributed with the straight oil groove of longitudinal extension.
The beneficial effects of the utility model: by setting up reinforcement platform in the side of spiral bevel gear setting circle, for arranging gear fastener hole, can ensure the tooth number of screw thread, again can weight reduction, reduce costs; Sphere inner chamber can increase the volume of inner chamber, and the external frame of planetary pinion, differential gear mates with sphere inner chamber, reduces the whole height of differential casing, makes overall structure more compact; Half shaft hole inner wall is provided with straight oil groove, is formed in casting process, eliminate one machining sequence.

Embodiment
Below by embodiment also by reference to the accompanying drawings, the utility model is described in further detail:
Shown in composition graphs 1-Fig. 4, a kind of piece differential cage body, adopt integrally casting shaping, the middle part of housing is provided with sphere inner chamber 1 for holding planetary pinion and differential gear, and planetary pinion and differential gear are arranged in sphere inner chamber 1.Two of housing is provided with half axis hole 2 communicated with sphere inner chamber 1, be respectively used to semiaxis (i.e. output shaft) is installed, differential mechanism is to while the semiaxis transferring power of both sides, both sides semiaxis is allowed to rotate with different rotating speeds, meet two sidecar wheels and make Unequal distance traveling with the form of pure rolling as far as possible, reduce the friction on tire and ground.
Housing is provided with the planetary gear shaft hole 3 of lateral direction penetrating sphere inner chamber 1, for installing planet pin, two planetary pinions are sleeved on planet pin relatively.The outer wall of housing horizontally outward extends to form spiral bevel gear setting circle 4, spiral bevel gear setting circle 4 is for installing spiral bevel gear, spiral bevel gear is fixedly mounted on spiral bevel gear setting circle 4, and drives differential casing to rotate together, is connected with the power input shaft of differential mechanism.
Housing is provided with the positioning pin hole 7 of a longitudinal extension for installing locating stud, locating stud inserts on the planet pin of locking planetary gear shaft hole 3, exits in planetary gear shaft hole 3 to prevent planet pin.
The side hoop of spiral bevel gear setting circle 4 is distributed with strengthens platform 5, and each reinforcement platform 5 is provided with the gear fastener hole 6 of a through spiral bevel gear setting circle 4 of longitudinal direction, spiral bevel gear is arranged on the one side not arranging and strengthen platform 5, and passes through screw lock.Half axis hole 2 inwall is distributed with the straight oil groove 8 of longitudinal extension.
Preferably, the reinforcement platform 5 on spiral bevel gear setting circle 4 totally eight, and circumferentially uniform; Gear fastener hole 6 and reinforcement platform 5 one_to_one corresponding, be therefore also eight.Each half axis hole 2 inwall is evenly equipped with three straight oil grooves 8, but is not limited to three.
