Abstract
The utility model discloses a novel auxiliary oil pump assembly for automatic transmission belongs to car technical field, including motor, oil pump and check valve, sealed through tang and oil blanket between motor and the oil pump, the motor passes through the operation of transmission shaft driving oil pump, and the oil -out at the oil pump is fixed to the check valve, prevents that oil from revealing, the oil inlet of oil pump with inhale oil filter and be connected. The utility model discloses when satisfying system machine oil flow demand, still to have solved because auxiliary oil pump when out of work, it reveals the problem that leads to the fact system's fuel delivery not enough.
Description
Technical field
This utility model belongs to automobile technical field, more particularly to a kind of new type auto change speed gear box auxiliary oil pump assembly.
Background technology
During hybrid power car load use, during vehicle low speed pure motor driving operating mode, due to automatic gear-box machinery
Pump input rotating speed is low, while mechanical pump volumetric efficiency is affected by factors such as temperature, outlet pressures, causes mechanical pump capacity not
Foot, so as to cause the shake of DCT main oil way of hydraulic system pressure, liquid controling element response time long, even results in clutch when serious
The failures such as friction plate scaling loss.And the gear that conventional automatic gearbox oil pump is relied primarily on clutch drives oil pump upper transfer gear
Operated.The traffic demand of FCL hydraulic systems, needs to design new auxiliary under to compensate the pure electronic operating mode of vehicle low speed
Oil pump.
The content of the invention
The purpose of this utility model patent is to provide a kind of new type auto change speed gear box auxiliary oil pump assembly, solves at a high speed
When the demand and auxiliary oil pump of rotation output system oil flow rate do not work, because its leakage causes asking for flow system flow deficiency
Topic.
What the technical solution of the utility model was realized in：
A kind of new type auto change speed gear box auxiliary oil pump assembly, including motor 1, oil pump 2 and check valve 3, the motor 1 with
Sealed by seam 4 and oil sealing 5 between oil pump 2, motor 1 drives oil pump 2 to operate by power transmission shaft, and check valve 3 is fixed on oil pump 2
Oil-out, the oil-in for preventing oily leakage, oil pump 2 is connected with oil adsorption filter 7.
Automatic gear-box auxiliary oil pump of the present utility model is so work:
When needing auxiliary oil pump to work, oil pump 2 is driven by motor 1, and by high speed the stream of output system demand is rotated
Amount.Simultaneously in order to prevent when auxiliary oil pump does not work, the problem for causing flow system flow not enough due to the leakage of auxiliary oil pump,
Increase check valve 3 in auxiliary oil pump assembly.
Compared with prior art, advantage of the present utility model is as follows：
This utility model is also solved due to when auxiliary oil pump does not work while system machine oil traffic demand is met,
Its leakage causes the not enough problem of system fuel delivery.
Description of the drawings
Fig. 1 is the structural representation of auxiliary oil pump assembly of the present utility model；
Fig. 2 is the structure principle chart of auxiliary oil pump assembly sealing of the present utility model；
Fig. 3 is the scheme of installation of auxiliary oil pump assembly of the present utility model；
In figure：Motor 1, oil pump 2, check valve 3, seam 4, oil sealing 5, gear box casing 6, oil adsorption filter 7, oil sump 8,
Oil pipe 9.
Specific embodiment
This utility model is further described below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of new type auto change speed gear box auxiliary oil pump assembly, including motor 1, oil pump 2 and unidirectional
Valve 3, is sealed between motor 1 and oil pump 2 by seam 4 and oil sealing 5；Motor 1 drives oil pump 2 to operate by power transmission shaft, check valve 3
The oil-out of oil pump 2 is fixed on, oily leakage is prevented.
Auxiliary oil pump assembly is bolted on gear box casing 6, and oil-in and the oil adsorption filter 7 of oil pump 2 connect
Connect, so as to the oil in oil sump 8 is drawn into into auxiliary oil pump 1, while check valve 3 is pumped out auxiliary oil pump by oil pipe 9
Oil delivery in hydraulic systems.
Automatic gear-box auxiliary oil pump of the present utility model is so work:
When needing auxiliary oil pump to work, oil pump 2 is driven by motor 1, and by high speed the stream of output system demand is rotated
Amount.Simultaneously in order to prevent when auxiliary oil pump does not work, the problem for causing flow system flow not enough due to the leakage of auxiliary oil pump,
Increase check valve 3 in auxiliary oil pump assembly.
