Description
Technical Field
The utility model belongs to the hydraulic component in the machinery trade, in particular to car is with two separation and reunion automatic transmission with supplementary electric oil pump.
Background
With the increasing demand for environmental protection improvement in various countries around the world, the hydraulic demand for novel efficient gearboxes is also increasingly outstanding, and the lubricating oil pump of the automobile transmission is gradually changed from a mechanical pump to an electric oil pump. At the present stage, the motor output end of the motor is connected with the pump through the spigot and the shaft coupling in the domestic production, the electric oil pump with the structure is usually large in size, the electric oil pump is not beneficial to the complete oil immersion of the electric oil pump in the gearbox, meanwhile, the spigot and the shaft coupling have fit clearance, the coaxiality of the electric oil pump assembly is easy to produce in the design and assembly, and the defects of large current, high noise, low efficiency, short service life and the like in the use process are further caused.
Disclosure of Invention
An object of the utility model is to overcome above-mentioned technique not enough, provide a compact structure, small, efficient, long service life's two separation and reunion automatic transmission are with supplementary electric oil pump.
The utility model provides a technical scheme that technical problem adopted is, two separation and reunion automatic transmission are with supplementary electric oil pump includes the oil pump body, the driving gear, the rotor shaft, the baffle, the electricity organism, the motor lid, ball bearing one, ball bearing two, the characteristics are, center department is equipped with the rotor shaft through ball bearing one and ball bearing two in the motor body and the motor lid, the right-hand member dress of rotor shaft is in the internal center department of oil pump, the overhead driving gear that is equipped with of right-hand member of rotor shaft in the oil pump body with the key, the oil pump body passes through baffle and motor lid right-hand member face fixed connection, driven gear is connected in the driving gear meshing transmission in the oil pump body, be equipped with the rotor on the internal rotor shaft of motor, the internal stator that is equipped with of rotor outlying motor, fixed connection magnet holder on the end of rotor shaft left side, inlay an axle head magnet in the magnet holder, fixed connection sensor assembly on the left end face of motor body.
The utility model has the advantages that: the auxiliary electric oil pump for the double-clutch automatic transmission adopts a continuous fastening structure, reduces the using quantity of parts, reduces the whole volume of the electric oil pump, and has simpler and more compact structure and more convenient manufacture and maintenance. In addition, the structure of one transmission shaft is adopted, the problem that the coaxiality of the coupling structure is poor in the design and assembly processes is eliminated to a greater extent, the electric oil pump is stable in the operation process, the noise is degraded, the working efficiency is improved, and the service life is long.

In the embodiment, referring to fig. 1, an auxiliary electric oil pump for a dual clutch automatic transmission is characterized in that a motor cover 11 is fixedly arranged on the right end face of a motor body 8, a first ball bearing 9 is arranged in a groove in the center of the motor body 8, and a second ball bearing 10 is arranged in a groove in the center of the motor cover 11. The rotor shaft 3 is arranged in the ball bearing I9 and the ball bearing II 10. The rotor 8-1 is fixed on the periphery of the rotor shaft 3, the stator 8-2 is arranged on the periphery of the rotor 8-1, and the stator 8-2 is fixed on the inner wall of the motor body 8. A magnet seat 5 is arranged in the left end head of the rotor shaft 3, and a shaft head magnet 6 is embedded in the magnet seat 5. The left end of the rotor shaft 3 is arranged at the center in the oil pump body 1, a driving gear 2 is arranged on the right end head of the rotor shaft 3 through a key, and the driving gear 2 is in meshing transmission connection with a driven gear 2-1. The oil pump body 1 is fixed on the left end face of the motor cover 11 through the partition plate 4, and the sensor assembly 7 is fixedly connected on the left end face of the motor body 8 through a positioning pin and a screw. A positioning block 12 is fixed in the lower part of the oil pump body 1 for positioning during installation.
The working principle of the utility model is that when the auxiliary electric oil pump for the double-clutch automatic transmission works, the power of a customer is input into the motor through the sensor assembly 7, and the position signal of the rotor 8-1 is transmitted to the outside. A rotor shaft 3 in the oil pump body 1 drives a driving gear 2 and a driven gear 2-1 to be in meshing transmission, an oil suction area and an oil discharge area are formed in a closed space in the oil pump body 1, oil flows in from an oil suction port and flows out from an oil discharge port, and flow and pressure are provided for a hydraulic system.
