Automobile torque converter is applied to the automatic catch gearbox of the forms such as AT, CVT, is one in car transmissions
Key components and parts.Its main function is the clutch instead of manual gear gearbox.Solves the shift of automatic catch gearbox
Problem simplifies the operating process of driver, reduces mechanical shock when shifting gears in vehicle traveling process.Fluid torque-converter
In its evolution, critical role is occupied in transmission case of automobile market with its outstanding performance.
With the continuous development of automotive engineering, gearbox is controlled to low grade locking development.Torque-converters in fluid power operating mode
Switching is mainly controlled by hydraulic oil between locking operating mode.Therefore, fluid torque-converter oil channel structures are its indispensable knots
One of structure.As oil consumption requirement, the requirement of shift speed and opportunity of shifting gears in vehicle traveling process is continuously improved in people, to becoming
The performance requirement of fast case is higher and higher, while requiring to shorten its axial dimension as far as possible.Correspondingly to the structure of fluid torque-converter
Size and oil channel structures also have higher requirement, it is desirable that shorten its axial ruler as far as possible while ensureing fluid torque-converter performance
It is very little.
As shown in Figure 1, the first bearing 19 of existing fluid torque-converter is arranged between turbine hub 17 and guard ring 18, the second axis
It holds 15 to be arranged between the guide wheel 16 and pump impeller hub 11 of the other side, first bearing 19 and second bearing 15 are located at same axis direction
On, this results in fluid torque-converter overall dimensions to become larger.
Invention content
The purpose of this utility model is that shortening gearbox axial dimension, and provide a kind of automobile shortening axial dimension
Use fluid torque-converter.
To achieve the goals above, the technical solution of the utility model is：
A kind of automobile fluid torque-converter shortening axial dimension, including pump impeller hub, turbine hub, guide wheel assembly, first axle
It holds and second bearing, the guide wheel assembly is arranged between pump impeller hub and turbine hub, first bearing and second bearing are installed respectively
Between the installation gap that turbine hub and guide wheel assembly and pump impeller hub and guide wheel assembly are formed, the guide wheel assembly includes along diameter
To inside race, one-way clutch, outer race, guide wheel and the guard ring being located between outer race and first bearing installed successively,
The outer diameter of guard ring is less than internal diameter of the outer diameter more than outer race of outer race, is characterized in that：One is offered on the guide wheel
Installation groove is enclosed, second bearing is arranged in installation groove, and the internal diameter of second bearing is more than the outer diameter of outer race.
Further, the material of the pump impeller hub and turbine hub is the 20CrMo after high-frequency quenching, its hardness is made to reach
To HRC58 or more, to ensure bearing working surface intensity, bearing needle can be made to directly act on contact surface, cancel existing fluid power and become
Bearing shim in square device shortens torque-converters axial dimension.
Compared with prior art, the utility model has the advantage of：
1, a circle installation groove is offered on guide wheel, second bearing is arranged in installation groove, and second bearing
Internal diameter be more than the diameter of outer race, second bearing and guide wheel can be made to be in same axial position, reduce the axis of second bearing
To installation space, and then make guide wheel closer to pump impeller.
2, the material of pump impeller hub and turbine hub is changed to the 20CrMo after high-frequency quenching, its hardness is made to reach
HRC58 or more can make bearing needle directly act on contact surface to ensure bearing working surface intensity, cancel existing hydraulic moment changeable
Bearing shim in device shortens torque-converters axial dimension.
