Abstract
The utility model discloses a differential motor for an electro-tricycle. The differential motor comprises a cavity body defined by a box cover (1) and a box body (2). A motor body is arranged outside the cavity body, a ventilating bolt hole (3) is formed in the lateral face of the upper portion of the box body (2), an oil draining hole (4) is formed in the lower portion of the box cover (1) and an oil filling hole (5) which is communicated with the cavity body is formed in the lateral face of the upper portion of the box cover (2). The differential motor for the electro-tricycle has the advantages of being simple in structure and convenient to use. By the adoption of the differential motor, not only can engine oil be filled into the box body conveniently, air pressure inside the box body be released automatically and the service condition of the engine oil be checked conveniently, but also the engine oil inside the box body can be drained completely, friction of the box body can be reduced, gears inside the box body are protected, service life is prolonged and the differential motor can be connected with a rear axle conveniently.
Description
Technical field
The utility model relates to a kind of electro-tricycle, the automobile-used differential mechanism of particularly a kind of electric three-wheel.
Background technique
The automobile-used differential speed motor of existing electric three-wheel mainly comprises the cavity that is surrounded by casing and housing, is outside equipped with motor at cavity, is provided with the ventilation bolt hole in the upper end of described casing, is provided with bolt in the ventilation bolt hole; Be provided with drain oil in described lower part of frame.This ventilation bolt hole mainly plays two effects, and the one, in cavity, inject lubricant oil by this bolt hole, the 2nd, play the effect of outside exhaust.Structure although it is so is feasible, but there is following deficiency in such structure: 1. by the oiling in cavity of ventilation bolt hole, after bolt must being taken out, adopt special-purpose oil can for oiling machinery to refuel, cause refueling process very inconvenient 2. when needs are exitted, the bolt taking-up could must be exitted, and, venting regularly, in case forget venting, will cause the cavity internal air pressure to raise, make seal ring and mould assembling face be subjected to high pressure and the oil impregnate phenomenon takes place.3. because drain oil is arranged on position on the upper side, bottom, when causing draining the oil, can't put only,, will can produce wearing and tearing, reduce working life internal gear of motor in case impurity is too much in the lubricant oil.
The model utility content
The purpose of this utility model just provide a kind of can the automobile-used differential speed motor of convenient oiling electric three-wheel.
The purpose of this utility model is to realize by such technological scheme, the automobile-used differential speed motor of a kind of electric three-wheel, comprise the cavity that surrounds by case lid and casing, be outside equipped with motor at cavity, be provided with the ventilation bolt hole in the casing upper side, bottom at described case lid is provided with drain oil, is provided with the tank filler sleeve that communicates with cavity in the case lid upper side.
Further, be provided with the casing labyrinth in casing, described casing labyrinth communicates with cavity and ventilation bolt hole respectively, is provided with dividing plate between described casing labyrinth and cavity, and dividing plate is provided with the vent that communicates with cavity.
Clean in order to drain the oil, described drain oil is positioned at the bottom of case lid, is provided with plug screw in described drain oil.
For the ease of observing the machine oil consumption, on case lid and be positioned at the tank filler sleeve front side and be provided with the oil rule hole, in the oil rule hole, be provided with oil rule.
For the ease of being connected with back axle, the exterior edge face of described cap is provided with bolt mounting holes, and described bolt mounting holes is 5-12.
Wherein, in the utility model, described bolt mounting holes is 10, can adapt to different back axle specifications like this.
Owing to adopted technique scheme; the utlity model has advantage simple in structure, easy to use; adopt it not only can in casing, add machine oil easily, discharge casing internal air pressure, the use condition of checking up Engine oil easily automatically; but also the machine oil of casing energy can be put only; reduce its friction, protection casing internal gear improves working life; and, can also be connected with back axle easily.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a housing structure schematic representation of the present utility model;
Fig. 2 is a cover structure schematic representation of the present utility model;
Fig. 3 is the rear view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, 2, 3, the automobile-used differential speed motor of a kind of electric three-wheel, comprise the cavity that surrounds by case lid 1 and casing 2, be outside equipped with motor at cavity, be provided with ventilation bolt hole 3 in casing 2 upper side, be provided with drain oil 4 in the bottom of described case lid 1, be provided with the tank filler sleeve 5 that communicates with cavity in case lid 2 upper side.
In the utility model, can be by this tank filler sleeve 5 easily to refueling in the cavity, simultaneously, by ventilation bolt hole 3, can play the effect of automatic release casing 2 internal air pressures, prevented because air pressure is too high, seal ring in the casing 2 is caused damage, prevented the generation of oil impregnate phenomenon.
Further be provided with, in order to prevent that the machine oil in the casing 2 from flowing out by the ventilation bolt hole, in casing 2, be provided with casing labyrinth 6, described casing labyrinth 6 communicates with cavity and ventilation bolt hole 3 respectively, be provided with dividing plate 7 between described casing labyrinth 6 and cavity, dividing plate 7 is provided with the vent 8 that communicates with cavity.Do like this and just can prevent that getting rid of of drive is oily flows out by tank filler sleeve 3 because gear rotates.
Further, described drain oil 4 is positioned at the bottom of case lid 1, is provided with plug screw 9 in described drain oil 4.Doing so just can be clean with the release of the machine oil in the cavity, prevent because the interior impurity of machine oil is too much, and generation is worn and torn to gear, reduces working life.
For the ease of observing oil level, the convenient oiling on case lid 1 and be positioned at tank filler sleeve 5 front sides and be provided with oil rule hole 10, is provided with oil rule 11 in oil rule hole 10.
For the ease of being connected with split type back axle, the exterior edge face of described case lid 1 is provided with bolt mounting holes 12, and described bolt mounting holes 12 is 5-12.
In the utility model, the bolt mounting holes 12 that is adopted is 10.Certainly, can be provided with voluntarily according to actual conditions.
