Abstract
The utility model provides a novel differential casing, belongs to the technical field of automobile transmission, and aims to solve the problems that in the prior art, a connector of a split-type differential casing falls out during usage, the end of a journal is easy to break to damage a transmission mechanism and the like. The novel differential casing comprises a casing body, a cavity, a left output shaft mounting hole, a left output shaft channel, a right output shaft mounting hole, a right output shaft channel, an input shaft mounting hole, a plate-shaped connector and the like. The novel differential casing is integrated, reasonable in design, simple in structure, and easy to process and produce, stability of the casing is improved effectively, safety is high, and meanwhile service life of a differential is prolonged.
Description
Technical field
The utility model belongs to the vehicle transmission technical field, is specifically related to a kind of differential casing.
Background technique
Differential mechanism is the main part that drives sedan-chair, and its effect is in the semiaxis transferring power of both sides, allows the both sides semiaxis with different rotating speed rotations, satisfies two sidecar wheels and does equidistantly not travel with the form of pure rolling as far as possible, reduces the friction on tire and ground.Differential mechanism is made up of mechanical parts such as differential left right shell body, planetary pinion, planet pin and differential gears, the power of motor enters the ransaxle differential mechanism through transmission shaft, drive planetary wheel carrier, drive left and right sides semiaxis, make left and right sidesing driving wheel with different speed rotations, to obtain good steering behaviour.
The differential casing of prior art by independently two the part form, couple together with connected elements such as bolts between them, because the Environmental Conditions of vehicle is comparatively complicated, connected element can occur coming off after long-term the use, and the axle journal root of the differential mechanism of this structure easily ruptures, damage driving mechanism, serious even can cause security incident generation, but because the shape and structure of differential mechanism and the restriction that size is subjected to installing environmental conditions, improve comparatively difficulty, as " 200920126339 differential right casing body ", a kind of differential right casing body is disclosed, the problem that it easily ruptures for the axle journal root that solves the couple structure differential mechanism, by the right shell body axle journal to being damaged easily, axle journal root and step end face are through mid frequency induction hardening heat treatment, and the transition arc radius of increase differential right casing axon neck root, concentrate with the stress that reduces differential right casing axon neck root, improved mechanical property and the mechanical strength at the axle journal root transition arc position between right shell body axle journal and the step end face.But because the natural deficiency that split type this body structure of differential mechanism exists only by the improvement of partial structurtes and intensity, still can't better promote the Safety performance of differential mechanism, eliminate accident defect.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of novel differential casing, coming off in use can appear in its connected element of eliminating split type differential casing in the prior art by all-in-one-piece structure, and the axle journal root easily ruptures problems such as damage driving mechanism.
For achieving the above object, the utility model has adopted following technological scheme: a kind of novel differential casing, the enclosure body 1 that comprises the integrally casting moulding, this enclosure body 1 is provided with the cavity 2 that planetary pinion and differential gear are installed, left end at cavity 2 is provided with left output shaft mounting hole 3 and left output shaft passage 4, cavity 2 right-hand members are provided with right output shaft mounting hole 5 and right output shaft passage 6, the lower end of cavity 2 is provided with input shaft mounting hole 7, and left output shaft passage 4, cavity 2 and right output shaft passage 6 connect mutually; Described enclosure body 1 arranged outside has the tabular link 8 of stepped distribution, and tabular link 8 is linked to be left output shaft passage 4 and enclosure body 1 and right output shaft passage 6 and is integral structure.
Differential casing described in the utility model is compared with existing split type housing and is had the following advantages: the moulding of housing integrally casting, and reasonable in design, simple in structure, be easy to manufacturing, can effectively improve the steadiness of housing, safe, increase the service life simultaneously.

Fig. 1 is differential casing structural representation described in the utility model.
Fig. 2 is differential casing end-face structure schematic representation described in the utility model.
The 1-enclosure body, 2-cavity, 3-left side output shaft mounting hole, 4-left side output shaft passage, the right output shaft mounting hole of 5-.The right output shaft passage of 6-, 7-input shaft mounting hole, the tabular link of 8-.
Embodiment
Below in conjunction with accompanying drawing and related description the utility model is further specified.
As illustrated in fig. 1 and 2, the described differential casing of present embodiment, the enclosure body 1 that comprises the integrally casting moulding, this enclosure body 1 is provided with the cavity 2 that planetary pinion and differential gear are installed, left end at cavity 2 is provided with left output shaft mounting hole 3 and left output shaft passage 4, cavity 2 right-hand members are provided with right output shaft mounting hole 5 and right output shaft passage 6, and the lower end of cavity 2 is provided with input shaft mounting hole 7, and left output shaft passage 4, cavity 2 and right output shaft passage 6 connect mutually; Described enclosure body 1 arranged outside has the tabular link 8 of stepped distribution, and tabular link 8 is linked to be left output shaft passage 4 and enclosure body 1 and right output shaft passage 6 and is integral structure.Differential casing integrally casting described in the utility model moulding, reasonable in design, simple in structure, be easy to manufacturing, can effectively improve the steadiness of housing, safe, increase the service life simultaneously.
