Description
Technical field
The utility model relates to twin-turbine torque converter technical field, specially a kind of twin-turbine torque converter machine
Core.
Background technique
China's loading machine largely uses twin-turbine torque converter, which is one kind that torque-converters is shunted in power.
Twin-turbine torque converter is made of hubcap, pump impeller, turbine group and guide wheel, is mounted between engine and speed changer, with hydraulic
Oil is working media, rises and transmits torque, bending moment, the effect of speed change and clutch, currently, a large amount of twin turbines hydraulic moment changeable in the market
Only only using being bolted together, twin-turbine torque converter in use can for the hubcap of device and the connection of pump impeller
Vibration is generated, prolonged use meeting causes hubcap to connect with pump impeller not secured enough so that bolt generation loosening, reduces double whirlpools
Take turns the service life of fluid torque-converter machine core.
Utility model content
The purpose of this utility model is to provide a kind of twin-turbine torque converter machine cores, to solve in above-mentioned background technique
It is proposing currently, the connection of the hubcap of a large amount of twin-turbine torque converter and pump impeller is only only using being bolted in the market
Together, twin-turbine torque converter can generate vibration in use, prolonged use meeting so that bolt generate loosening,
The problem of causing hubcap to connect with pump impeller not secured enough, reducing the service life of twin-turbine torque converter machine core.
To achieve the above object, the utility model provides the following technical solutions: a kind of twin-turbine torque converter machine core, packet
Hubcap is included, pump impeller is connected on the right side of the hubcap, turbine group, the right side of the hubcap are connected between the hubcap and pump impeller
Upper and lower ends offer mounting groove, and the left side upper and lower ends of the pump impeller are connected with expansion lantern ring, two expansion lantern rings
It is plugged on the inner cavity of mounting groove.
Preferably, the hubcap is bolted with pump impeller.
Preferably, the expansion lantern ring and mounting groove are interference fit.
Preferably, the length of the mounting groove is longer than expansion lantern ring.
Compared with prior art, the utility model has the beneficial effects that the utility model increases expansion sleeve on pump impeller
Ring enables pump impeller closely to link together with hubcap, increases the stability of its connection, forms rigid connection,
Loosening will not be generated under prolonged vibration, connects it stronger.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is the utility model mounting groove schematic diagram；
Fig. 3 is that the utility model expands lantern ring schematic diagram.
In figure: 1 hubcap, 2 pump impellers, 3 turbine groups, 4 mounting grooves, 5 expansion lantern rings.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of twin-turbine torque converter machine core, including
Hubcap 1, the right side of hubcap 1 are connected with pump impeller 2, and turbine group 3, the right side upper and lower two of hubcap 1 are connected between hubcap 1 and pump impeller 2
End offers mounting groove 4, and the left side upper and lower ends of pump impeller 2 are connected with expansion lantern ring 5, and two expansion lantern rings 5 are plugged on installation
The inner cavity of slot 4.
Wherein, hubcap 1 is bolted with pump impeller 2, and expansion lantern ring 5 and mounting groove 4 are interference fit, mounting groove 4
Length is longer than expansion lantern ring 5.
Working principle: the left side upper and lower ends of pump impeller 2 are respectively connected with expansion lantern ring 5, and the right side upper and lower ends of hubcap 1 are opened
Equipped with mounting groove 4, the inner cavity that lantern ring 5 is plugged on mounting groove 4 is expanded, is plugged into expansion lantern ring 5 from the right side of pump impeller 2 using bolt
Inner cavity, expansion lantern ring 5 is expanded by bolt compresses, so that expansion lantern ring 5 is connected to the inner cavity of mounting groove 4, so that pump impeller 2 and cover
Wheel 1 can closely fit together, and increase the stability of its connection, form rigid connection, under prolonged vibration
Loosening will not be generated, connects it stronger.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
