Abstract
A leakproof structure which is arranged between an electric generator and a crank case comprises the electric generator and the crank case; a sealing device is arranged between the electric generator and the crank case; the sealing device comprises a separating plate and a rear end cover, an O-shaped sealing ring and a sealing gasket. According to the leakproof structure which is arranged between the electric generator and the crank case, the separating plate which is arranged between the electric generator and the crank case rear end enables the electric generator and the crank case to be connected transitionally; the rear end cover of the crank case is thickened; the crank case rear end cover and the separating plate are sealed through an O-shaped sealing ring end surface; the separating plate and the electric generator are sealed through the sealing gasket; the separating plate, the electric generator and the rear end cover are guaranteed well sealing due to fastening through bolts. The leakproof structure between the electric generator and the crank case has the advantages of being low in cost and good in sealing effect and solving the problem of water entering, dust proof and the like during operation of the electric generator.
Description
Technical field
The present invention relates to hybrid power automobile power assembly, and in particular to the connection sealing knot between electromotor and crankcase
Structure.
Background technology
Now whole world Ge great depots produce one after another Green Vehicle, and wherein rechargeable hybrid power vehicle is also to give priority to product
One of product.In today that petroleum resources are increasingly in short supply, rechargeable hybrid power vehicle has good development prospect.Most cases
Under, the car is driven by motor with electric-only mode and is travelled, when power battery charged state is reduced to a certain scope, by starting
Machine and generating set into increasing journey system start generate electricity, the electric energy for sending directly feed motor-driven vehicle traveling, reach increasing
Plus the purpose of course continuation mileage.
At present, the electromotor of rechargeable hybrid power vehicle typically borrows the platform product of existing fuel engines, not specially
Door exploitation, is not especially modified to electromotor main parts size such as crankcase etc., improves platform generalization, reduces to reach
Cost, and shorten the purpose of project development progress.Under this background, the electromotor and engine crankcase of hybrid vehicle
The connection of rear end face is affected by general layout and electromotor this body structure, and electromotor can not be effectively direct with the end face of crankcase
Sealing, or the sealing by the way that larger change is carried out to crankcase rear end face to ensure with motor is needed, for existing platform
Electromotor, Change cost is high.
The content of the invention
In view of the foregoing defects the prior art has, it is an object of the invention to provide a kind of low cost, good sealing effect
Electromotor and crankcase connection sealing structure, the problems such as solving electromotor and intake and be dust-proof in running.
To solve the above problems, the technical solution adopted in the present invention is：
A kind of sealing structure between electromotor and crankcase, including electromotor, crankcase, between electromotor and crankcase
Sealing device is provided with, the sealing device includes dividing plate, rear end cap, O-ring seal, sealing gasket.
Transition connection is carried out by increasing by a dividing plate between electromotor and crankcase rear end face, crankcase rear end cover adds
O-ring seal end face seal is adopted between thickness, with dividing plate, dividing plate is sealed again with electromotor by sealing gasket, and uses bolt respectively
Fastener guarantee dividing plate and motor, rear end cap excellent sealing.
The present invention has compared with prior art following major advantage：Due to connecting using bulkhead transition, and pass through O respectively
Type sealing ring and sealing gasket carry out the mode of pressurized crankcase and electromotor replace by change crankcase rear end face come with generating
The mode of secret envelope, to the main parts size of available engine platform change is not required to, and Change cost is low, in addition, also ensuring that song
Axle box is reliably connected with electromotor, and prevents electromotor from intaking, and enters dirt, affects the performance and service life of motor, so as to
Electromotor maintenance cost after sale is reduced, it is economical and practical.

Fig. 2：Dividing plate and crankcase joint face figure；
Fig. 3：The rear end cover structure schematic diagram of crankcase.
Fig. 4：Electromotor, crankcase and dividing plate assembling schematic diagram.
In figure：Dividing plate 1, sealing gasket 2, O-ring seal 3, rear end cap 4, electromotor 5, crankcase 6, dividing plate connects with crankcase
Connect hole 11, rear end cap mounting groove 12, dividing plate and motor connection hole 13, rear end cap and bulkhead seal face 41.
Specific embodiment
With reference to the accompanying drawings and detailed description, the present invention is described in further detail：
Referring to Fig. 1, dividing plate 1 is sealed by sealing gasket 2 with the end face of electromotor 5.
Referring to Fig. 2, Fig. 3 and Fig. 4, in order to make rear end cap 4 good fit with dividing plate 1, dividing plate middle setting rear end cap is installed
Groove 12, afterwards, by rear end cap 4, coordinates with rear end cap mounting groove 12 and installs, and the bottom of rear end cap mounting groove 12 is provided with through hole, leads to
Hole circumference is provided with O-ring seal 3, and end face seal is carried out with bulkhead seal face 41 by O-ring seal 3 and rear end cap.Finally,
Dividing plate 1 passes through dividing plate and crankcase connecting hole 11 with the rear end face of crankcase 6, is fastened using bolt；Dividing plate 1 and motor by every
Plate and motor connection hole 13, are fastened using bolt.
By figure 1 above, the connection of Fig. 2 and Fig. 3 each several parts, as shown in figure 4, can prevent completely during generator operation
Extraneous dust, water etc. enters electromotor, affects the performance and service life of electromotor.
