Further, described gap is 15mm.
Preferably, described leakproof oil gluten is triangle lamellar body, rectangular lamellar body and square lamellar body.
Preferably, the described vent 30mm of described leakproof oil gluten distance.
Preferably, the thickness of described leakproof oil gluten is 6mm.
The beneficial effects of the utility model specifically are:
1, of the present utility modelly comprise gear box casing for electric automobile gear-box ventilation place oil baffle structure, vent and at least one leakproof oil gluten, described vent is arranged on the described gear box casing, described leakproof oil gluten be arranged on the inwall of described gear box casing and be positioned at described vent around, thereby utilize lubricating oil splash that leakproof oil gluten stops that the gear pair of electric automobile gear-box stirs near vent, design ingenious, simple for structure, substantially do not increasing gearbox weight and do not reducing under the situation of gearbox inner space, solve the phenomenon of gearbox breather plug leakage of oil, be suitable for large-scale promotion application.
2, the leakproof oil gluten for electric automobile gear-box ventilation place oil baffle structure of the present utility model also plays the effect of reinforcing housing, design ingenious, simple for structure, substantially do not increasing gearbox weight and do not reducing under the situation of gearbox inner space, solve the phenomenon of gearbox breather plug leakage of oil, be suitable for large-scale promotion application.
Description of drawings
Fig. 1 is the schematic perspective view of a specific embodiment of the present utility model.
Embodiment
In order more to be expressly understood technology contents of the present utility model, describe in detail especially exemplified by following examples.Should be understood that embodiment only is for explanation the utility model, rather than to restriction of the present utility model.
See also shown in Figure 1, of the present utility modelly comprise gear box casing 2, vent 3 and at least one leakproof oil gluten 6 for electric automobile gear-box ventilation place oil baffle structure, described vent 3 is arranged on the described gear box casing 2, described leakproof oil gluten 6 be arranged on the inwall of described gear box casing 2 and be positioned at described vent 3 around.
Described vent 3 is used for installing breather plug, is used for being communicated with the gearbox interior or exterior space, so that the balance inner and outer air pressure.Leakproof oil gluten 6 is except playing near the effect that stops lubricating oil splash also to have reinforcement gear box casing 2 intensity vent 3.
Described leakproof oil gluten 6 can be installed on the described gear box casing 2, also can be integrally formed with described gear box casing 2, and in specific embodiment of the utility model, described leakproof oil gluten 6 is integrally formed with described gear box casing 2.
