Abstract
The invention belongs to the technical field of automobile hydraulic torque converters, in particular to an automobile hydraulic torque converter. The automobile hydraulic torque converter comprises a turbine hub, an inner base ring, a guide wheel body, a retainer ring installed on the side, close to the turbine hub, of the guide wheel body, and a bearing installed on the turbine hub. The automobile hydraulic torque converter is characterized in that the turbine hub is provided with an axial channel, and an axial oil hole is formed in the retainer ring and the guide wheel body; one end of the axial channel communicates with a gap between a locked clutch and the turbine hub, and the other end of the axial channel communicates with the axial oil hole; the axial oil hole communicates with an oil duct in the inner base ring; and the retainer ring directly makes contact with the bearing. The hydraulic torque converter not only improves an oil discharge structure of a traditional hydraulic torque converter and guarantees the service life of the bearing, but also is more compact in structure through a new oil passing structure, and reduces the axial dimension.

Technical field
The invention belongs to automobile torque converter technical field, and in particular to automobile fluid torque-converter.
Background technology
Automobile torque converter is applied to the form automatic transmission gearbox such as AT, CVT, is a pass in car transmissions
Key parts.Its Main Function is the clutch that instead of manual gear gearbox, and the gearshift for solving automatic catch gearbox is asked
Topic, simplifies the operating process of human pilot, reduces the mechanical shock when automobile is shifted gears in the process of moving；Fluid torque-converter exists
In its evolution, with its outstanding use reliability, outstanding performance, in transmission case of automobile market with occupying
Critical role.
With the continuous development of automotive engineering, its gearbox controls to low-grade locking to develop, existing market realized 10 kilometers/
Gearbox instruction torque converter locking during h～20 kilometer/h.Torque-converters switch between fluid power operating mode and locking operating mode mainly by
Hydraulic oil is controlled.Therefore, fluid torque-converter oil channel structures are one of its indispensable structures.With constantly carrying for automotive engineering
Height, the raising that people are required to automobile oil consumption in the process of moving are improved constantly to requirement of the shift speed with gearshift opportunity, this
Also there is higher requirement to the physical dimension and oil channel structures of fluid torque-converter.
As depicted in figs. 1 and 2, between the oil channel structures of existing fluid torque-converter, including lockup clutch 1 and hubcap 2
The oil inlet passage 3 that opens up, a part of hydraulic oil are entered in fluid torque-converter cavity 4, in pump impeller body 5 and whirlpool by oil inlet passage 3
Circulation working oil is formed between wheel body 6；Space of another part hydraulic oil between turbine body 6 and lockup clutch 1 flow to be closed
It is deposited in space between lock clutch 1 and turbine hub 7 and for a long time herein；Circulation work oil Tong Guo not be opened on guard ring 8
If groove and the space oil return between guide wheel body 9 and pump impeller hub 10 to inside race 11 oil duct in.
In order to prevent wearing and tearing between 8 groove of bearing 12 and guard ring on turbine hub 7, between existing guard ring 8 and bearing 12
Pad 13 is provided with, the axial space increase of fluid torque-converter cavity is this results in, the overall dimensions of fluid torque-converter increases,
The size of gearbox is caused to increase, manufacturing cost increase.
The content of the invention
In order to solve the problems, such as in background technology, the invention provides a kind of automobile fluid torque-converter, improves tradition
Oil outlet structure in fluid torque-converter, not only ensures the service life of bearing；Fluid power is caused by new excessively oily structure simultaneously
Torque-converters structure is compacter, reduces its axial dimension.
The present invention concrete technical scheme be：
The invention provides a kind of automobile fluid torque-converter, including turbine hub, inside race, guide wheel body, installed in guide wheel
Guard ring and bearing installed in turbine hub on of the body near turbine hub side；
Its improvements is：Axial passage is offered on the turbine hub；Axial direction is offered on the guard ring and guide wheel body
Oilhole；Described axial passage one end is connected with the space between lockup clutch and turbine hub, the other end and the axial oilhole
It is connected；The axial oilhole is connected with the oil duct on inside race；The guard ring and bearing directly contact.
It is an advantage of the current invention that：
Present invention eliminates pad between the groove opened up on guard ring and groove and bearing, while increasing on turbine hub
Axial passage, not only ensure that the working environment (reducing the service wear of bearing, extend the working life of bearing) of bearing, while
Fluid torque-converter internal structure can be made compacter, reduce its axial dimension；

15- inside races, 16- axial directions oilhole.
Specific embodiment
As shown in Figure 3 and Figure 4, fluid torque-converter proposed by the present invention, is optimized to the oil circuit of fluid torque-converter, takes
The groove and pad 12 disappeared on the left of guard ring 8 with 7 bearing of turbine hub, 11 contact surface, can so make the 11 functional contact face of bearing be
One complete face, improves the working environment of bearing with this, improves bearing life, and the modification of this oil channel structures causes bearing to exist
Allow to use thin-wall bearing during type selecting, reduce torque-converters axial dimension；Axial passage is opened up on turbine hub 7 simultaneously
13, axial oilhole 16 is offered on guard ring 8 and guide wheel body 9；13 one end of axial passage and lockup clutch 1 and turbine hub 7 it
Between space connection, the other end is connected with the axial oilhole 16；Axial oilhole 16 is connected with the oil duct on inside race 15,
Oil duct of the final working oil from inside race 15 flows out.
Therefore, in fluid power operating mode, hydraulic oil is into entering for opening up between lockup clutch 1 and hubcap 2 for fluid torque-converter
Friction plate 14 is separated with hubcap 2 by oily passage 3 by pressure, and flows into fluid torque-converter cavity 4, a portion hydraulic oil
Circulation working oil is formed between pump impeller body 5 and turbine body 6, another part is by the sky between lockup clutch 1 and turbine hub 7
On gap, turbine hub 7, axial passage 13 and axial oilhole 16 flow to the passage of inside race 15, realize oil return.
