And increase assembly precision in assembling process.
It is to be directly connected to bell housing with gear box oil bottom case again, does not need to make in bell housing using oil return line
Hydraulic oil can flow back into oil sump, keep structure simpler, repair it is more convenient.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the partial structurtes enlarged diagram in Fig. 1.
Specific embodiment
Below in conjunction with attached drawing detailed description of the present invention embodiment.
As shown in Figure 1, the structure of the present embodiment include Flywheel disc 4, bell housing 7, gasket 8, flexible disc 9, crank shaft bolt 6,
Gearbox is installed bolt 3, bell housing installation bolt 12 and transition rings 10, the Flywheel disc 4 and is set in bell housing 7, Flywheel disc 4 one
End face connects engine crankshaft output end, and other end connects flexible disc 9, and the flexible disc 9 connects the input terminal of gearbox 11,
Gasket 8 is equipped between the flexible disc 9 and Flywheel disc 4, Flywheel disc 4, gasket 8 and flexible disc 9 connect by the way that crank shaft bolt 6 is fixed
It connects, while 8 flexible disc 9 of gasket is installed bolt 3 by gearbox with gearbox 11 and is fixedly connected, the transition rings are set to bell housing
End face is installed bolt 12 by bell housing and is fixedly connected with bell housing 7.
In the present embodiment, there is a recessed portion, the speed change towards an end face center of gearbox on the Flywheel disc 4
Case installation bolt 3 is located in the recessed portion in the projection on Flywheel disc 4.
In the present embodiment, 4 center of Flywheel disc has a through-hole, is installed with bearing 2, the gearbox 11 in through-hole
The nose of input terminal is fixedly connected with 2 inner ring of bearing.
In the present embodiment, 7 lower wall of bell housing is equipped with an oil return opening 15, and the oil return opening 15 is along bell housing 7
It extends radially through, one end positioned at 7 lateral wall of bell housing of oil return opening 15 is equipped with a plug 16, which is closed, and returns
Side wall between 7 end face of hydraulic fluid port 15 and bell housing is equipped with a through-hole 14, oil return opening 15 to be connected to 7 end face of bell housing, institute
It states position just opposite with the through-hole 14 in transition rings 10 and also is provided with a through-hole 13, be connected to 7 lateral through aperture of bell housing, the mistake
The through-hole 13 crossed on ring 10 is connected to the oil sump of gearbox 11, by the hydraulic oil in bell housing 7 back to gearbox 11
In oil sump.
Working principle is as follows:
In the accompanying drawings, size A is the distance between 4 end face of engine flywheel disk and 5 end face of engine start gear ring, size
A is to guarantee that engine start gear ring 5 can normally be engaged with the gear ring on Flywheel disc 4, to enable the engine to normally open
It is dynamic.
Size B is the bolt head of the gearbox installation bolt 3 to fixed flexible disc 9 to 4 recessed portion bottom of Flywheel disc
Distance value, the size of size B directly influence the problem of whether bolt head interferes with 4 recessed portion of Flywheel disc.
Therefore the present embodiment be the further improvement on available engine and gearbox docking mechanism, Flywheel disc 4 with
Add gasket 8 between flexible disc 9, add transition rings between Flywheel disc 4 and gearbox, so as to be effectively ensured size A and
The value of size B engages engine start gear ring normally with flywheel ring gear, while gearbox is installed the bolt head of bolt 3 and flown
4 recessed portion bottom of wheel disc does not interfere.
Flywheel disc 4 is installed on the engine by crank shaft bolt 6；Flexible disc 9 installs bolt 3 by gearbox and is mounted on change
On fast case；Bolt 3 is installed by gearbox to be attached gasket 8, flexible disc 9 and gearbox 11；Bell housing installs bolt 12
Gearbox and bell housing, transition rings are mounted on one, wherein engine has been made of one with bell housing.In the course of work, hair
Motivation is output power on gearbox by Flywheel disc 4, gasket 8, flexible disc 9.Increase axis on transmission input nose
It holds, circular runout in motion process can be reduced, increase assembly precision in assembling process.
The gearbox can have gear box hydraulic oil, have one to return below bell housing to wet type docking is connected in bell housing
Oil is returned to gear box oil bottom case by hydraulic fluid port.The prior art is usually to increase pipeline at this oil return opening, guides to gear box oil bottom
At shell, maintenance assembly is inconvenient.The oil return opening is blocked with plug, the drilling on bell housing and transition rings, with the oil return
Oral pore is connected, and so that the gear box oil in bell housing is directly passed through connecting hole and is back in gear box oil bottom case, to reduce pipeline
Arrangement, improve assembly and maintenance convenience and efficiency.
