Background technology:
The axle housing of existing passenger vehicle vehicle bridge is integrally-built mostly, is then machined into through one piece casting, whole
It is bridge bag in the middle of the axle housing of body structure, as the housing of passenger vehicle reductor and differential mechanism, the both sides of bridge bag are axle tube structure, use
Take turns edge system and rack system in installing, but the axle housing of this structure can not be applied in electric motor coach system, with people
Environmental consciousness raising, the electric motor coach of pollution-free zero-emission gradually replaces existing fuel oil passenger vehicle, is badly in need of research and development a kind of suitable
Close the axle housing of the vehicle bridge of electric motor coach.
Content of the invention:
In sum, in order to overcome the shortcomings of prior art problem, the invention provides a kind of electric motor coach is with split type
Axle housing and its processing method, it is that the Casting Axle Housing Design of the vehicle bridge of electric motor coach is become Split type structure, including axle centre housing and both sides
Central siphon, central siphon is fixed on the both sides of axle centre housing, the integrated motor of axle centre housing, reductor and differential mechanism, and it disclosure satisfy that electricity
The needs of dynamic passenger vehicle.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of split type axle housing of electric motor coach, wherein: include left axle pipe assembly, right axle pipe assembly and axle centre housing, in
The left side of section axle housing is fixed with left axle pipe assembly, and the right side of axle centre housing is fixed with right axle pipe assembly, described left axle pipe assembly
And flange, the described left axle pipe assembly stage casing identical, described with right axle pipe assembly structure are respectively fixed with right axle pipe assembly
Integrated motor, reductor and differential mechanism in axle housing.
Technical scheme it may also is that realizing, described left axle pipe assembly, right axle pipe assembly respectively with
Axle centre housing friction welding is fixed.
Technical scheme it may also is that realizing, on described left axle pipe assembly and right axle pipe assembly respectively
Flange is fixed with by friction welding.
The electric motor coach as above processing method of split type axle housing, wherein: first by left axle pipe blank and right axle pipe
Blank is contained in the left and right sides of frock respectively by bolt, then left axle pipe blank and right axle pipe blank is machined out, then
The left axle pipe of completion of processing and right axle pipe are pulled down from frock, finally by left axle pipe and right axle pipe, friction welding is fixed on respectively
The left and right sides of axle centre housing.
Technical scheme it may also is that realize, described frock includes bridge bag and frock flange, bridge bag
Both sides be respectively and fixedly provided with frock flange.
The invention has the benefit that
1st, the present invention is that the Casting Axle Housing Design of the vehicle bridge of electric motor coach is become Split type structure, including the axle of axle centre housing and both sides
Pipe, central siphon is fixed on the both sides of axle centre housing, the integrated motor of axle centre housing, reductor and differential mechanism, and it disclosure satisfy that electric motor coach
The needs of car.
2nd, the processing method of the axle housing of the present invention can machine left axle pipe and right axle pipe simultaneously, and time processing ensures left axle pipe
And the axiality of right axle pipe, thus ensureing to install the axiality of rear axle housing both sides, improve conforming product rate；Due to left axle pipe and the right side
Axle tube structure is identical, therefore once can process two pieces central siphon, and production efficiency is high.
3rd, the tool structure of the processing method of the axle housing of the present invention simple, easy to use can be by existing fuel oil passenger vehicle
Axle housing processes, and sufficiently can utilize existing frock and equipment, input cost is low, thus effectively reducing the life of enterprise
Produce cost, improve market competitiveness of enterprises.
Brief description:
Fig. 1 is the structural representation of the axle housing of the present invention；
Fig. 2 is the structural representation of the frock of the present invention；
