Description
Technical field
The present invention relates to a kind of technology in electric vehicle field, specifically a kind of novel parking actuator sealing knot
Structure.
Background technology
Retarder used in new energy power drive system is opposite small compared with for orthodox car, and parking actuator volume without
Too big variation, while parking actuator oil resistance is poor, therefore will usually be hung over outside reduction case outside parking actuator.
To avoid in system operation, lubricating oil passes through parking actuator and retarder in retarder cavity assembly knot
Structure flows into parking actuator, it is also necessary to is effectively sealed to the coupling part of the two.The general sealing for using oil sealing at present
Form.But oil sealing higher price, in addition oil sealing sealing is high to matching requirements, is unfavorable for reducing cost.
Invention content
The present invention is directed to deficiencies of the prior art, it is proposed that a kind of novel parking actuator sealing structure,
Oil-returning structure is arranged in parking actuator and retarder coupling part, and the lubricating oil that the two coupling part is entered to the overwhelming majority returns
Oil processing, then be sealed using elastic sealed body, when reducing the action of parking actuator output shaft, elastic sealed body is in dynamic
The pressure of retarder side under sealing state realizes effectively sealing.
The present invention is achieved by the following technical solutions：
The present invention includes parking actuator and retarder, wherein parking actuator is equipped with parking crank, and parking crank stretches into
Retarder cavity is simultaneously rotatablely connected with reducer shell；
The reducer shell is being equipped with sealed groove in face of parking actuator side, and correspondingly, parking actuator is equipped with
Sealing flange；Sealing flange and sealed groove are sealed by elastic sealed body, between elastic sealed body and seal groove base
The side wall of sealed groove is equipped with oil return opening.
The elastic sealed body is O-ring.
Preferably, the sealed groove and/or sealing flange use double-layer structure, double-layer structure to be connected using reducing sleeve；
Each layer structure corresponds to parking actuator and retarder is respectively equipped with an elastic sealed body.
The parking actuator is set to retarder top.
Technique effect
Compared with prior art, oil-returning structure is arranged in parking actuator and retarder coupling part in the present invention, to big absolutely
The lubricating oil of part into the two coupling part does oil return processing, then seals oil resistance using elastic sealed body, reduces parking and holds
Elastic sealed body is in the pressure of retarder side under dynamic sealing state when row device output shaft acts, and realizes effectively sealing；And
When parking actuator output shaft attonity, elastic sealed body are in static seal, there is more reliable safety relative to oil sealing dynamic sealing
Sealing effect；It is simple using elastic sealed body sealing mounting process, it is not necessarily to assembly tooling fixture, and its price is low, is conducive to
Reduce production cost.
Description of the drawings
Fig. 1 is the dimensional structure diagram of embodiment 1；
Fig. 2 is the overall structure diagram of embodiment 1；
Fig. 3 is sealed groove and sealing flange structural schematic diagram in embodiment 1；
Fig. 4 is schematic diagram of the embodiment 1 using double-layer sealing structure；
In figure：It is parking actuator 1, parking crank 2, retarder 3, reducing sleeve 5, sealed groove 41, sealing flange 42, O-shaped
Sealing ring 43, oil return opening 44.
Specific implementation mode
Below in conjunction with the accompanying drawings and specific implementation mode the present invention will be described in detail.
Embodiment 1
As shown in Figure 1, Figure 2 and Figure 3, the present embodiment includes parking actuator 1 and retarder 3, wherein parking actuator 1
Equipped with parking crank 2, parking crank 2 stretches into retarder cavity and is rotatablely connected with reducer shell；
The reducer shell is being equipped with sealed groove 41, correspondingly, parking actuator 1 in face of 1 side of parking actuator
Equipped with sealing flange 42；Sealing flange 42 and sealed groove 41 are sealed by O-ring 43, at 41 bottom of O-ring 43 and sealed groove
The side wall of sealed groove 41 is equipped with oil return opening 44 between portion.
As a kind of deformation of the present embodiment, the sealing flange 42 uses double-layer structure, each layer structure to correspond to parking and hold
Row device 1 and retarder 3 are respectively equipped with an O-ring 43, and double-layer structure is connected by reducing sleeve 5, as shown in Figure 4.
Parking actuator 1 is set to 3 top of retarder in the present embodiment, and reducer gear stirs the lubricating oil splash of oil splashing
Amount to top is less；Further, it by controlling the fit-up gap of sealed groove 41 and parking crank 2, reduces lubricating oil and flies
Splash the amount in sealed groove；It is preferred that using the used in new energy vehicles parking actuator of the 0.2mm recommended in JB/ZQ 4245-1997
Fit clearance (can select smaller fit clearance) under conditions of process and assemble allows；And enter the lubrication of sealed groove 41
Oil is back to retarder cavity by oil return opening, avoids accumulating, and improves the reliability of O-ring sealing.
It is emphasized that：It the above is only presently preferred embodiments of the present invention, not the present invention made in any form
Limitation, it is every according to the technical essence of the invention to any simple modification, equivalent change and modification made by above example,
In the range of still falling within technical solution of the present invention.
