Technical field
The present invention relates to a kind of hydraulic conveyor of the automatic transmission for vehicle.Or rather, the present invention relates to the hydraulic conveyor for the automatic transmission of vehicle, its rotational speed that can control electric motor by the hydraulic pressure based on being transported to cooler prevents unnecessary hydraulic slip.
Background technique
Recently,, due to the reinforcement of worldwide soaring oil prices and exhaust emissions regulation, its whole strength is put into raising fuel economy by motor vehicle manufacturers.
The raising of fuel economy can realize by the unnecessary power consumption that minimizes oil hydraulic pump.
At present automatic transmission has low-pressure hydraulic pump and high-pressure hydraulic pump to improve fuel economy.Therefore, the hydraulic pressure being produced by low-pressure hydraulic pump is transported to low-pressure section (for example, torque converter, cooling equipment, and lubricating utensil), and the hydraulic pressure being produced by high-pressure hydraulic pump is transported to high-pressure section (for example, the friction member of selectivity operation in the time of conversion).
In further details, the hydraulic pressure of automatic transmission produces for low-pressure section (that is, being produced by low-pressure hydraulic pump) conventionally, and the needed hydraulic pressure of high-pressure section is produced by high-pressure hydraulic pump, is then transported to high-pressure section.

With reference to figure 1, traditional hydraulic conveyor is applicable to the low hydraulic pressure being produced by low-pressure hydraulic pump 2 to be transported to as the low-pressure section 4 of torque converter (T/C), cooling segment and lubricated part, and the high hydraulic pressure being produced by high-pressure hydraulic pump 6 is transported to the high-pressure section 8 of the friction member relevant to conversion for operation.
The hydraulic pressure being produced by low-pressure hydraulic pump 2 is controlled and becomes stable hydraulic at low pressure modulating valve 10 place, be then transported to low-pressure section 4, and low pressure modulating valve 10 is controlled by the pilot pressure of the first solenoid SOL1.
If the low hydraulic pressure of carrying from low-pressure hydraulic pump 2 is increased to high hydraulic pressure by high-pressure hydraulic pump 6, the control that the hydraulic pressure increasing by high-pressure hydraulic pump 6 is so subject to septum valve 12 becomes stable hydraulic, is then transported to high-pressure section 8.

Fig. 2 is according to the schematic diagram of the hydraulic conveyor of the automatic transmission of exemplary of the present invention.
With reference to figure 2, be applicable to the low hydraulic pressure being produced by low-pressure hydraulic pump 102 to be transported to as the low-pressure section 104 of torque converter (T/C), cooling segment and lubricated part according to the hydraulic conveyor of exemplary of the present invention, and the high hydraulic pressure being produced by high-pressure hydraulic pump 106 is transported to for operating and the high-pressure section 106 of changing relevant friction member.
Low hydraulic pressure is the low pressure of the operation of promotion torque converter (T/C) and Cooling and Lubricator, and high hydraulic pressure is the high pressure that promotes the operation of multiple friction members.
Low-pressure hydraulic pump 102 and high-pressure hydraulic pump 106 interconnect by an axle, and drive by electric motor M.Electric motor M controls by transmission control unit.
The hydraulic pressure being produced by low-pressure hydraulic pump 102 is subject to the control of low pressure modulating valve 110 and becomes stable hydraulic, is then transported to low-pressure section 104.For this purpose, low-pressure hydraulic pump 102 receives by intake line 112 oil being stored in oil sump P, and low hydraulic pressure is disposed to the first low pressure line 114.
Low pressure modulating valve 110 is controlled by being arranged on the elastic force of resilient member 116 of its side and the hydraulic pressure of the first low pressure line 114 that is transported to the opposite side of resilient member 116.Low pressure modulating valve 110 is recycled to intake line 112 by the first recirculating line 118 by the part of the hydraulic pressure of carrying by the first low pressure line 114, to control hydraulic pressure.
The part of the low hydraulic pressure of carrying from low-pressure hydraulic pump 102 is increased to high hydraulic pressure by high-pressure hydraulic pump 106, and high hydraulic pressure is disposed to pressure duct 120.The hydraulic pressure of pressure duct 120 is controlled by septum valve 122, is then transported to high-pressure section 108.
The pilot pressure, the hydraulic pressure that is arranged on the elastic force of the resilient member 124 of side described in it and is transported to the pressure duct 120 of its opposite side of the solenoid valve SOL of septum valve 122 by being transported to its side are controlled.Septum valve 122 is recycled to the second low pressure line 130 by the second recirculating line 126 by the part of the hydraulic pressure of carrying by pressure duct 120, to control hydraulic pressure.
