Description
Technical field：
The utility model is related to battery truck process technology, more particularly to a kind of battery truck brake hub cap and trailing wheel sealing
Structure.
Background technology：
Electric car, i.e. electrically driven vehicle, also known as electricity are driven.Electric car is divided into alternating current electric vehicle and DC electric car.It is logical
The electric car often said is originated using battery as energy, by parts such as controller, motors, converts electrical energy into mechanical energy fortune
It is dynamic, change the vehicle of speed with control electric current size.
The trailing wheel of battery truck is driving wheel, and hind axle is that brake hub cap is set with drive shaft, drive shaft, and tradition is set
Be present larger defect in meter, do not sealed between hind axle and brake hub cap mainly, battery truck works in sleety weather, gesture
It must make to enter rainwater between brake hub cap and drive shaft, it is another on the one hand with the abrasion between brake wheel and drive shaft
Aspect rainwater corrosion, hind axle is difficult to dismantle with brake hub cap when ultimately resulting in maintenance battery truck, even if disassembling also needs
Substantial amounts of time and manpower are wasted, under efficiency is at a fairly low.
Utility model content：
In order to make up prior art problem, the purpose of this utility model is to provide a kind of battery truck brake hub cap and trailing wheel
Axle sealing structure, reasonable in design, it is ensured that sealing will not enter rainwater, convenient pair between brake hub cap and hind axle
Trailing wheel is dismantled and installed when repairing, and greatly improves the efficiency removed and installed.
The technical solution of the utility model is as follows：
It is set with battery truck brake hub cap and trailing wheel axle sealing structure, including the brake hub cap with axis hole, axis hole
Hind axle, it is characterised in that described hind axle is provided with limited step, hind axle latter end is provided with external screw thread, hind axle
It is set with to screw outside interior sealing baffle plate, inner seal ring, brake hub cap, exterior seal ring, exterior seal ring successively and external seal is installed
It is described interior sealing baffle plate, outer close in baffle plate, described inner seal ring, the sealing mounting groove at exterior seal ring insertion axis hole two ends
Inner seal ring, exterior seal ring are sealed in sealing mounting groove when block plate works.
Described battery truck brake hub cap and trailing wheel axle sealing structure, it is characterised in that in described brake hub cap
Outer wall is provided with inner convex platform, outer lug boss is integrally formed, and inner convex platform, outer lug boss are distributed in axis hole two ends bead, inner convex platform, outer lug boss
Centre bore and axis hole are coaxial and wait big, and centre bore two ends are respectively equipped with sealing mounting groove.
Described battery truck brake hub cap and trailing wheel axle sealing structure, it is characterised in that described hind axle it is spacing
Step is to being optical axis between thread segment, and interior sealing baffle plate is pad, and interior sealing barrier slides are set in optical axis section, interior sealing gear
The back side is withstood on limited step when plate works.
Described battery truck brake hub cap and trailing wheel axle sealing structure, it is characterised in that described external seal baffle plate rotation
Conjunction is installed on hind axle thread segment, sealing locking exterior seal ring during work.
The utility model has the advantages that：
The utility model reasonable in design, it is ensured that sealing will not enter rain between brake hub cap and hind axle
Water, is dismantled and is installed when conveniently being repaired to trailing wheel, greatly improve the efficiency removed and installed.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model.
Embodiment：
Referring to accompanying drawing：
It is set with battery truck brake hub cap and trailing wheel axle sealing structure, including the brake hub cap 1 with axis hole, axis hole
Hind axle 2, hind axle 2 is provided with limited step 3, and the latter end of hind axle 2 is provided with external screw thread 4, be set with successively on hind axle 2 in
Screwed outside sealing baffle 5, inner seal ring 6, brake hub cap 1, exterior seal ring 7, exterior seal ring 8 and external seal baffle plate 8 is installed, it is interior
, will when interior sealing baffle plate 5, external seal baffle plate 8 work in sealing ring 6, the sealing mounting groove 9 at the insertion axis hole of exterior seal ring 7 two ends
Inner seal ring 6, exterior seal ring 7 are sealed in sealing mounting groove 9.
Brake hub cap 1 inside and outside wall, which is provided with, is integrally formed inner convex platform 10, outer lug boss 11,11 points of inner convex platform 10, outer lug boss
It is distributed in axis hole two ends bead, inner convex platform 10, the centre bore of outer lug boss 11 and axis hole are coaxial and wait big, and centre bore two ends are respectively equipped with close
Seal mounting groove 9.
The limited step 3 of hind axle 2 is to being optical axis between thread segment 4, and interior sealing baffle plate 5 is pad, and interior sealing baffle plate 5 is slided
Dynamic to be set in optical axis section, the back side is withstood on limited step 3 when interior sealing baffle plate 5 works.
External seal baffle plate 8, which is screwed, to be installed on the thread segment of hind axle 2, and external seal baffle plate 8 can be stop nut, during work
Sealing locking exterior seal ring 7.
The part meeting of the thread segment of hind axle 2 is exposed, and external seal baffle plate 8 is placed on thread segment outside, can easily be existed by corrosion
On the thread segment of hind axle 2, the utility model can ensure that sealing will not enter rainwater, side between brake hub cap and hind axle
Dismantled and installed when just being repaired to trailing wheel, greatly improve the efficiency removed and installed.
