Description
Technical field
The present invention relates to fluid torque-converter technical fields, and in particular to a kind of high-power fluid power change with monoblock type guide wheel
Square device.
Background technique
Currently, being commonly heavily loaded upward slope using the vehicle of high-power fluid torque-converter in the market, and road conditions are more complicated, need
Frequent bending moment is wanted, this has resulted in high-power fluid torque-converter working condition and has needed to continue bending moment.Therefore, in certain fields, it is
Use can preferably be matched with Some vehicles or engineering machinery model by meeting this drive characteristic, and guide wheel must be remain stationary
It is motionless, need it is direct be connected and fixed with external oil pump sleeve and case of transmission, to reach fluid torque-converter at runtime
It can continue to keep bending moment characteristic.However, the Guiding wheel structure of fluid torque-converter is all that assembly parts are assembled by several components in the market
It forms, technique manufacture is relative complex, and at high cost, guide wheel intensity is not high.In addition, pump impeller component inner bearing is all external, bearing
It is poor to be directly exposed to outer quality stability.
Summary of the invention
The purpose of the present invention is to provide a kind of high-power fluid torque-converter with monoblock type guide wheel, the fluid torque-converters
Part type is not only reduced, product is simplified, also enhances the intensity of guide wheel itself, protects bearing, and manufactures and safeguards
It is convenient.
To achieve the above object, the invention adopts the following technical scheme:
A kind of high-power fluid torque-converter with monoblock type guide wheel, including pump impeller, turbine, guide wheel and front shroud；The pump
Wheel and front shroud surround a cavity, and guide wheel and turbine are sequentially embedded installation in the cavity；The pump impeller includes pump impeller shell, sets
Set the bearing one being arranged in tooth set middle cavity in the intermediolateral tooth set of pump impeller shell and insertion；The guide wheel includes leading
The guide wheel pellet among guide wheel body and with guide wheel body integrally casting shaping is arranged in wheel ontology and insertion.
Further, the turbine is connected with guide wheel by bearing two；The bearing two is successively from turbine and guide wheel
Centre passes through.
Further, the turbine is connected with front shroud by bearing three；The bearing three is arranged between front shroud and turbine.
Further, support ring is installed on the side wall of the guide wheel body；The support baffle ring and bearing one closely paste
It closes.
Further, the bearing one is interference fitted with tooth set.
Further, the side wall of the guide wheel body is equipped with support ring mounting groove.
Further, the guide wheel body uses aluminium material, and the guide wheel pellet uses No. 45 steel materials.
Further, the inner wall of the pump impeller shell is equipped with pump impeller blade；The guide wheel body is equipped with guide vane.
Compared to the prior art, the invention has the benefit that
(1) guide wheel body in the present invention uses aluminum component, and abrasion is very fast, is not suitable for directly matching with external oil pump sleeve
It closes.The present invention inlays the guide wheel pellet big into intensity when guide wheel body is cast inside it, and guide wheel body and guide wheel pellet are being cast
It is formed an entirety after making, reduces part type, simplifies product, enhances the intensity of guide wheel itself.
(2) present invention by pump impeller bearing one setting tooth set in, avoid because outer boundry particle and bearing one contact due to it is right
Bearing one causes to wear, to preferably protect bearing one.

Fig. 3 is the structural schematic diagram of pump impeller.
Wherein:
101, pump impeller shell, 102, tooth set, 103, bearing one, 104, pump impeller blade, 200, guide wheel, 201, guide wheel body,
202, guide wheel pellet, 203, support baffle ring, 300, turbine, 400, front shroud, 500 bearings three.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing:
A kind of high-power fluid torque-converter with monoblock type guide wheel as shown in Figure 1, including pump impeller, turbine 300, guide wheel
200 and front shroud 400.The pump impeller and front shroud 400 weld together, and the two surrounds an annular cavity, guide wheel 200 and turbine
300 are sequentially embedded installation in the cavity.The turbine 300 is connected with guide wheel 200 by bearing two；The bearing two successively from
The centre of turbine 300 and guide wheel 200 passes through.The turbine 300 is connected with front shroud 400 by bearing 3 500；The bearing three
500 are arranged between front shroud 400 and turbine 300.
As shown in Fig. 2, the guide wheel 200 include guide wheel body 201 and insertion setting the centre of guide wheel body 201 and with lead
Take turns the guide wheel pellet 202 of 201 integrally casting shaping of ontology.Support ring 203 is installed on the side wall of the guide wheel body 201；Institute
Support baffle ring 203 is stated to fit closely with bearing 1.The side wall of the guide wheel body 201 is equipped with support ring mounting groove, is used for
Installation support baffle ring 203.The support baffle ring 203, the bearing 1 being used to support in pump impeller.The guide wheel body 201 uses
Aluminium material, the guide wheel pellet 202 use No. 45 steel materials.Guide wheel of the present invention eliminates existing fluid torque-converter
Preceding baffle ring, retaining ring, outer ring, inner ring and rear baffle ring in guide wheel, change traditional handicraft, when guide wheel body 201 is cast, just will
Guide wheel pellet 202 is inlayed among guide wheel body 201, forms an entirety after casting the two.Guide wheel pellet 202 and guide wheel body
After 201 castings are integrated, in the inwall processing spline of guide wheel pellet 202, to be connected with external oil pump sleeve.In the present invention
When the high-power fluid torque-converter works, guide wheel 200 is directly connected and fixed with external oil pump sleeve and case of transmission,
Guarantee the performance of bending moment always.Present invention reduces the manufacturing procedures of guide wheel, reduce the type of part, simplify product, together
When enhance the intensity of guide wheel itself.
As shown in figure 3, the pump impeller includes pump impeller shell 101, setting in the intermediolateral tooth of pump impeller shell 101 set 102
And the bearing 1 in tooth 102 middle cavities of set is arranged in insertion.The bearing 1 and 102 interference fit of tooth set.Institute
The inner wall for stating pump impeller shell 101 is equipped with pump impeller blade 104；The guide wheel body 201 is equipped with guide vane.The bearing one
103 are fixed between support baffle ring 203 and the lateral wall of tooth set 102.By the way that the assembly of bearing 1 is covered inside 102 in tooth, energy
Enough avoiding outer boundry particle from contacting with bearing one damages bearing one, preferably protects bearing one.
The course of work of the invention are as follows:
Pump impeller is connected by the elastic plate being connected on front shroud with engine flywheel, by its rotation of driven by engine.Pump
Wheel converts the mechanical energy of engine to the kinetic energy of the intracavitary working fluid of torque-converters, and makes liquid stream along pump impeller blade direction high velocity stream
Enter turbine, push turbine rotation, then export through output shaft, and is transmitted to driven member acting.Liquid stream acts on the torque on guide wheel
Turbine is reacted on, so that the torque on turbine is equal to the sum of pump impeller and the torque of guide wheel, so that the output torque of guide wheel be made to be greater than
Input torque generates automatic torque-changing.
Embodiment described above only describe the preferred embodiments of the invention, not to model of the invention
It encloses and is defined, without departing from the spirit of the design of the present invention, those of ordinary skill in the art are to technical side of the invention
The various changes and improvements that case is made should all be fallen into the protection scope that claims of the present invention determines.
