Speed change, which seems, wastes one's talent on a petty job.If using fixed reduction ratio, drive system structure be simply, but can generate accelerating ability and
The poor defect of grade climbing performance.Therefore it is proposed that the scheme of two speed transmission, with big retarding ratio when running at a low speed, realize compared with
Good starting performance meets the requirement of the max speed with small reduction ratio when running at high speed.
The automatic transmission of current electric car uses single oil pump.Oil pump is used to provide to the hydraulic system of speed changer
Pressure, hydraulic system are used to control the operation of clutch or associated power transmitting and converting element in speed changer, to realize two
Switching between gear.
However, the automatic transmission of single oil pump generallys use electronic oil pump, electric power is required under the slow-speed of revolution and high revolving speed
It maintains oil pump to operate, is unfavorable for energy saving.
Summary of the invention
In order to solve the above technical problems, the present invention proposes a kind of automatic transmission with external double oil pumps comprising shell
Body and it is located at the intracorporal hydraulic control system of shell and rotating ratio switching mechanism, the hydraulic control system is for driving the revolving speed
It is acted than switching mechanism, so that the automatic transmission switches between the first gear and the second gear, it is described automatic
Speed changer further includes the first oil pump and the second oil pump, and first oil pump and the second oil pump can provide for the hydraulic system
Oil pressure.
According to the preferred embodiment of the present invention, first oil pump and the second oil pump are each by oil suction line and fuel-displaced
Oil circuit is connect with the hydraulic control system.
According to the preferred embodiment of the present invention, first oil pump and the second oil pump are mounted on the outer of the shell
Side.
According to the preferred embodiment of the present invention, first oil pump is driven by motor, and second oil pump is driven by motor
The intracorporal rotating element driving of dynamic or shell.
According to the preferred embodiment of the present invention, second oil pump only works in the high revolving speed of the input shaft of speed changer.
Detailed description of the invention
Fig. 1 is the working principle diagram of the automatic transmission of one embodiment of the present of invention；
Fig. 2 is the external structure schematic diagram of the automatic transmission of one embodiment of the present of invention.
Specific embodiment
Generally speaking, proposed by the present invention is a kind of automatic transmission comprising shell and be located at the intracorporal hydraulic control of shell
System processed, rotating ratio switching mechanism, the hydraulic control system for driving the rotating ratio switching mechanism to be acted so that
The automatic transmission is obtained to switch between the first gear and the second gear.Also, the automatic transmission further includes the first oil
Pump and the second oil pump, first oil pump and the second oil pump can provide oil pressure for the hydraulic system.Of the invention is this
Double oil pump designs, allow the hydraulic control system of speed changer according to the working condition of speed changer using different operation of oil pump
Mode, such as an oil pump is only used in some cases, and work at the same time two oil pumps.
According to the present invention, first oil pump and the second oil pump each by oil suction line and fuel-displaced oil circuit with it is described hydraulic
Control system connection.Also, for the ease of the installation of oil pump and for different speed changers or vehicle, it can easily replace oil pump
Model.Preferably described first oil pump and the second oil pump are mounted on the outside of the shell.
In addition, heretofore described rotating ratio switching mechanism preferably comprises first clutch and second clutch, it is described
First oil pump is driven by motor, and second oil pump is driven by motor or the intracorporal rotating element driving of shell.And described second
Oil pump only works in the high revolving speed of the input shaft of speed changer.
Fig. 1 is the working principle diagram of the automatic transmission of one embodiment of the present of invention.As shown in Figure 1, automatic transmission
For two axis structures, it includes input axle assembly I, countershaft assembly M, output assembly O and shells 1.Input axle assembly I,
Countershaft assembly M, the rotation centerline for exporting assembly O are parallel, and input axle assembly I, countershaft assembly M, output assembly O are equal
It is installed on shell.The input axle assembly I includes input shaft, a gear driving gear shaft, two gear driving gear axis, a gear
Gear shifting actuating mechanism A1, second gear gear shifting actuating mechanism A2, a gear clutch C1, second gear clutch C2 etc..Countershaft assembly M includes
Jackshaft, a gear driven gear, second gear driven gear, main reducing gear driving gear etc..Exporting assembly O includes that main reducing gear is driven
Gear, differential assembly etc..
In this embodiment, a gear gear shifting actuating mechanism A1, second gear gear shifting actuating mechanism A2, a gear clutch C1 and second gear
Clutch C2 is as the rotating ratio switching mechanism, so that the automatic transmission is cut between the first gear and the second gear
It changes.
In addition, do not show hydraulic system in Fig. 1, the hydraulic system is used to control one and keeps off clutch and second gear clutch
Movement.
Fig. 2 is the external structure schematic diagram of the automatic transmission of above-described embodiment.In the figure, the shell of automatic transmission
1 main inside element is not shown, and basically illustrates the structure in the outside of shell.As shown in Fig. 2, the first oil pump 2 and
Two oil pumps 3 are respectively arranged in the outside of shell and spaced apart.The shell and the shell of first oil pump 2, the second oil pump 3
1 is fastenedly connected, and the first oil pump 2 is driven by motor, and the second oil pump 3 is then driven by the bearing inside speed changer.
First oil pump 2, the second oil pump 3 are connected separately with oil suction line and fuel-displaced oil circuit, oil suction line and fuel-displaced oil circuit with
The hydraulic control system 4 of enclosure interior connects.Enclosure interior hydraulic control system is adjusted the pressure of fuel-displaced oil circuit, so as to
The movement of control one gear clutch C1 and second gear clutch C2.Specifically, the first oil pump 2 is connected by the first fuel-displaced oil circuit 51
