Abstract
The utility model discloses an integrative differential mechanism, its technical scheme main points are, including the casing, be equipped with the differential subassembly in the casing, the casing both sides are the step form that supplies output tooth joint, and the casing is topped bar and is equipped with the first screw hole that is used for with output tooth fixed connection on the lateral wall. Set the casing to the step shape, export like this the tooth just can the joint on the step, then construct at the connection fixed knot who utilizes first screw hole, can guarantee to export the drive differential mechanism that the tooth can be stable and rotate. This kind of structure, output tooth just can realize with the dismantling of differential mechanism, can change the output tooth of different specifications on differential mechanism.
Description
Technical field
This utility model relates to electric automobiles, particularly to one one differential mechanism.
Background technology
Electro-tricycle is that with motor-driven three-wheel means of transport, this electro-tricycle is divided into household type, shipping type and factory's type Multiple Type by purposes as power source with storage battery.The storage battery of electro-tricycle uses tubular type Large Copacity, left and right lining, deep discharge, towed storage battery, and the requirement of the continuous discharge that adapts to work long hours, storage battery normally uses 2 years, and inner capacities does not subtracts.The motor of electro-tricycle uses DC series excitation traction formula to have brush or brushless electric machine, and motor internal is provided with speed governing step-up system, and normal use is hardly damaged, it is ensured that output powerful；Being additionally provided with parts the most important in electro-tricycle, these parts are: the differential gear housing being connected with motor output shaft.
A core component in differential gear housing is exactly differential mechanism, existing notification number is the Chinese patent of CN203431125U, disclose the power attachment structure of a kind of electric-tricycle differential gear-box, but output gear therein one whole with differential mechanism, this structure cannot change output gear, single differential mechanism can not adapt in differential gear housing under structure.
Utility model content
The deficiency existed for prior art, the purpose of this utility model is to provide a kind of one differential mechanism be easy to and separate with output gear.
Above-mentioned technical purpose of the present utility model has the technical scheme that a kind of one differential mechanism, including housing, differential assembly it is provided with in described housing, it is step-like that described housing both sides are for output gear clamping, and described housing sidewall of topping bar is provided with for fixing the first screw hole being connected with output gear.
By technique scheme, housing being arranged to step shape, such output gear just can be connected to above step, is then utilizing the connection fixed structure of the first screw hole, it can be ensured that the drive differential mechanism that output gear can be stable rotates.This structure, it is detachable that output gear can be realized as with differential mechanism, can change the output gear of different size on differential mechanism.
This utility model is further arranged to: described housing is docked with right shell by symmetrical left housing and forms, described left housing be equipped with on right shell for fixing the second screw hole being connected.
By technique scheme, the structure that the structure of the second screw hole can effectively achieve a butt joint can facilitate the splicing of housing to assemble, and the structure of the second screw hole can allow left housing relatively stable with what right shell docked.And left housing and right shell are symmetrical, so installing when, output gear is either stuck in the left side or the right and can be carried out.
This utility model is further arranged to: described first screw hole quantity runs through the left and right sides of described housing, and described first screw hole quantity is four, and described first screw hole is circumferentially uniformly distributed.
By technique scheme, four equally distributed screws ensure that the stable connection of housing and output wheel, does not haves, during operating, situations such as rocking, it is ensured that housing can stablize the transmission effectively realizing strength.
This utility model is further arranged to: described second screw hole quantity is two and is circumferentially uniformly distributed.
Pass through technique scheme, owing to needing to utilize screw to be fixed between left housing and right shell, guarantee that it can connect each other more tight, but affect the structure of housing to not punch too much, so have only to two equally distributed screw holes and just can complete the connection in structure.
In sum, this utility model in contrast to the housing having the beneficial effect that left and right splicing of prior art can be easy to people's dismounting over the entire structure, different output gears can be fixed on different both sides by people simultaneously, the structure that whole screw connects can effectively realize enclosure interior and fix with outside, dismounting is fixed up efficient and convenient, time saving and energy saving.

Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
A kind of one differential mechanism, including housing 1, differential assembly it is provided with in housing 1, the both sides of housing 1 are all that the power transmission shaft with tire is connected, the clamping of the spline in power transmission shaft and housing 1, housing 1 both sides are and supply the step-like of output gear clamping, and step-like structure just can allow output gear be stuck in above, it is ensured that its fixing-stable.Housing 1 sidewall of topping bar is provided with for fixing the first screw hole 21 being connected with output gear.Installing when, need to be arranged on by output gear outside housing 1, whole one differential mechanism is arranged on inside differential gear housing, output gear engages with the train of reduction gears within differential gear housing, power is after motor passes over, transmission through gear train is last again through the rotating shaft rotation driving whole one differential mechanism drive both sides of output gear, so guarantees the normal advance of electro-tricycle.
Such as Fig. 1 to Fig. 2, housing 1 is docked with right shell 12 by symmetrical left housing 11 and forms, and is provided with symmetrical step-like structure above left housing 11 and right shell 12.First screw hole 21 runs through left housing 11 and right shell 12, and its quantity is 4.Left housing 11 be equipped with for fixing the second screw hole 22 being connected on right shell 12, docking left housing 11 with right shell 12 when, left housing 11 can be mutually aligned with right shell 12, then screw is screwed on, realizing left housing 11 to be connected with right the fixing of shell 12, the structure that screw is screwed in the second screw hole 22 is as shown in FIG..First screw hole 21 is that aperture is consistent with the second screw hole 22, and such first screw hole 21 can be fixedly connected with same screw with the second screw hole 22, and be convenient for people to is fixing.And the first screw hole 21 is circumferentially uniformly distributed with the second screw hole 22, it is ensured that the internal and outside connection of housing 1 all can keep uniform force stable.
The above is only exemplary embodiment of the present utility model, and not for limiting protection domain of the present utility model, protection domain of the present utility model is determined by appended claim.
