Preferably, it is equipped on the oil circuit at hydraulic pump inlet and outlet both ends and on the oil circuit at electronic pump inlet and outlet both ends
Filter.
Preferably, overflow valve is additionally provided between the hydraulic pump and gearshift magnetic valve, the overflow valve is arranged in hydraulic pump
On oil circuit between the filter and gearshift magnetic valve of outlet end.
After adopting the above technical scheme, the utility model has the following beneficial effects:
A kind of power shifting hydraulic oil container provided by the utility model is collected living in shift clutch using gearbox oil sump
There are the hydraulic oil of partial compromise caused by gap with mobile cavity for plug, can separate hydraulic system oil and gear box oil,
When oil mass is lower than certain limit value in hydraulic reservoir, then hydraulic pressure system will be returned to after the oil filtering in gearbox oil sump
It unites in fuel tank, solves the problems, such as hydraulic system luboil cleanness；In conclusion the utility model has structure simple, stabilization can
Lean on, it is economical and practical the advantages that, have very big market value, should be widely promoted application.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of power shifting hydraulic oil container of the utility model.
Wherein: fuel tank 1, hydraulic pump 2, oil sump 3, electronic pump 4, sensor 5, the shift clutch of the first shift clutch 6, second
Device 7, the first gearshift magnetic valve 8, the second gearshift magnetic valve 9, mobile cavity 10, piston 11, filter 12, overflow valve 13.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
In the present invention unless specifically defined or limited otherwise, term " installation ", " connected ", " connection ", " Gu
It is fixed " etc. terms should broadly understood, for example, it may be being fixedly connected, may be a detachable connection, or integral；It can be
Mechanical connection, is also possible to be electrically connected；It can be directly connected, two can also be can be indirectly connected through an intermediary
The interaction relationship of connection or two elements inside element.It for the ordinary skill in the art, can basis
Concrete condition understands the concrete meaning of above-mentioned term in the present invention.
As shown in Figure 1, the present embodiment provides a kind of power shifting hydraulic oil container, including fuel tank 1 and at least two shift gears from
Clutch is equipped with the hydraulic pump 2 that hydraulic oil in fuel tank 1 is supplied to shift clutch between the fuel tank 1 and shift clutch,
Between the hydraulic pump 2 and shift clutch be equipped with control shift clutch oil circuit transformation gearshift magnetic valve, it is described shift gears from
Clutch is also connected with the oil sump 3 for collecting shift clutch leakage hydraulic oil, and being equipped between the oil sump 3 and fuel tank 1 will be oily
Hydraulic oil provides the electronic pump 4 of oil dropping apparatus 1 in pond 3, is equipped with the sensor 5 being electrically connected with electronic pump 4 in the fuel tank 1.
Wherein, two shift clutch are arranged in parallel on the outlet oil circuit of hydraulic pump 2, respectively first shift gears from
Clutch 6 and the second shift clutch 7, the gearshift magnetic valve also are provided with two, respectively connect with the first shift clutch 6
First gearshift magnetic valve 8 and the second gearshift magnetic valve 9 connecting with the second shift clutch 7, stating shift clutch includes movement
Chamber 10 and the piston 11 being arranged in mobile cavity 10, the oil sump 3 are connected to by oil circuit with mobile cavity 10, the hydraulic pump 2
