Description
Technical Field
The utility model relates to the field of fluid transmission devices, in particular to a locking type hydraulic torque converter.
Background
With the high-speed development of the automobile industry in China, the automatic transmission is widely applied to modern cars, and the hydraulic torque converter is one of core components of the automatic transmission of the AT and the CVT. Torque converters utilize the flow of fluid to smoothly transfer engine torque to an automatic transmission. Inside the torque converter is an annular device filled with automatic transmission oil between the engine and the automatic transmission. The existing sedan is widely used as a single-stage double-phase three-element locking type comprehensive hydraulic torque converter consisting of a pump impeller, a turbine, a guide wheel and a locking clutch. The pump wheel is a driving part, is connected with the flywheel through a cover assembly welded with the pump wheel into a whole, converts mechanical energy into liquid energy, guides the liquid to impact the turbine blades, enables the blades to rotate so as to drive the turbine, realizes conversion of the liquid energy into the mechanical energy, the turbine is a driven part and is connected with the transmission input shaft, the guide wheel between the two impellers is fixed on an automatic transmission oil pump cover through a one-way clutch and a guide wheel shaft sleeve, and the locking clutch is arranged between the cover assembly and the turbine. The connection between the main components of a motor vehicle torque converter, such as the pump impeller assembly, the stator assembly, the turbine runner assembly, the cover assembly and the lockup clutch assembly, is well documented in the prior art.
Disclosure of Invention
The utility model aims at a hydraulic torque converter with smaller axial space, and meets the arrangement requirement of the axial dimension of the hydraulic torque converter by changing the structure of a lockup clutch assembly.
The technical scheme adopted for realizing the purpose of the utility model is that the locking type hydraulic torque converter comprises: pump wheel assembly, guide pulley assembly, turbine assembly, lockup clutch assembly and lid assembly.
The turbine assembly includes a turbine shell, a turbine sleeve, and a turbine sleeve rivet.
The lockup clutch assembly includes a lockup dial and a lockup dial rivet.
The lockup clutch assembly is mounted between the cover assembly and the turbine assembly.
The locking collar is riveted to the turbine housing by means of a locking collar rivet.
The utility model has remarkable technical effects and mainly has the following effects:
1) The torque converter axial dimension is reduced.
2) Can be widely applied to automobile hydraulic torque converters.
Drawings
FIG. 1 is a schematic diagram of a prior art torque converter lockup dial ring;
FIG. 2 is a schematic view of the structure of a torque converter lockup dial ring of the present utility model;
in the figure: pump impeller assembly 1, stator assembly 2, turbine assembly 3, turbine shell 301, turbine sleeve 302, turbine sleeve rivet 303, lockup clutch assembly 4, lockup dial 401, lockup dial rivet 402.
Detailed Description
The present utility model is further described below with reference to examples, but it should not be construed that the scope of the above subject matter of the present utility model is limited to the following examples. Various substitutions and alterations are made according to the ordinary skill and familiar means of the art without departing from the technical spirit of the utility model, and all such substitutions and alterations are intended to be included in the scope of the utility model.
Example 1:
referring to fig. 1-2, a lockup torque converter includes: pump impeller assembly 1, guide pulley assembly 2, turbine assembly 3, lockup clutch assembly 4 and lid assembly 5.
The turbine assembly 3 includes a turbine housing 301, a turbine bushing 302, and a turbine bushing rivet 303.
The lockup clutch assembly 4 includes a lockup dial 401 and a lockup dial rivet 402.
The lockup clutch assembly 4 is mounted between the cover assembly 5 and the turbine assembly 3.
The locking collar 401 is riveted to the turbine housing 301 by means of a locking collar rivet 402, which makes it possible to achieve a smaller axial dimension of the torque converter.
When the locking type hydraulic torque converter works, the torque of the engine is transmitted to the turbine shell 301 through the locking shifting ring 401, then is transmitted to the spline of the turbine shaft sleeve 302 through the turbine shell 301, and finally is transmitted to the input shaft of the transmission.
Example 2:
with reference to fig. 1 to 2, the purpose of this patent is, for a torque converter with a small axial space, to satisfy the arrangement requirements of the axial dimensions of the torque converter by changing the structure of the lockup clutch and the lockup dial ring.
The technical scheme adopted for achieving the purpose of the utility model is that the locking shifting ring and the turbine shell are riveted together by adopting a rivet mode, so that the smaller axial dimension of the torque converter can be achieved.
The working process of the utility model comprises the following steps: the locking shifting ring and the turbine shell are riveted together, and torque of the engine is transmitted to the turbine shell through the locking shifting ring, then transmitted to the turbine shaft sleeve spline through the turbine shell and finally transmitted to the input shaft of the transmission.
The utility model has the main effects that:
1) Reducing the torque converter axial dimension;
2) The utility model can be widely applied to the automobile hydraulic torque converter.
