Abstract
The invention relates to a hydraulic coupler. The front part of a pump wheel is provided with an input shaft, the inner back part of the pump wheel is provided with an output shaft, a bearing and a turbine are arranged on the output shaft, and blades of the turbine are 1 to 4 pieces fewer than blades of the pump wheel. The hydraulic coupler has the advantages that the structures of the turbine and the pump wheel and the number of the blades are improved, so that the transmission efficiency is improved, and the moment acting on the turbine is greater when the rotating speed of an engine is higher.
Description
Technical field
The present invention relates to mechanical part field, particularly relate to a kind of hydraulic couplers.
Background technique
Hydraulic couplers take liquid as a kind of nonrigid coupling device of working medium, also known as fluid coupling.The pump impeller of hydraulic couplers and turbine form an airtight active chamber that liquid-circulating can be made to flow, and pump impeller is contained on input shaft, and turbine cartridge is on output shaft.When power engine (internal-combustion engine, motor etc.) band driven input shaft rotates, liquid is centrifuged formula pump impeller and throws away.Namely this high-speed liquid promotes turbine and rotates after entering turbine, by the energy transferring that obtains from pump impeller to output shaft.Final liquid returns pump impeller, forms the flowing that goes round and begins again, the characteristic of hydraulic couplers because of active chamber different and variant from the shape of pump impeller, turbine.As the oily emptying by hydraulic couplers, Coupler is just in disengaged condition, can play clutch.Owing to there is liquid flowing loss in hydraulic couplers, drive line efficiency is than being low during alone clutch.At present, the application of hydraulic couplers on automobile reduces day by day.
Summary of the invention
In order to overcome the problems such as hydraulic couplers transmission efficiency is low, the invention provides a kind of hydraulic couplers.
The technological scheme that the present invention is adopted for achieving the above object is: hydraulic couplers, and input shaft is installed in pump impeller front portion, and in pump impeller, output shaft is installed at rear portion, output shaft is installed bearing and turbine.
The number of blade 1-4 sheet fewer than pump impeller of described turbine.
Hydraulic couplers of the present invention, made improvement to the structure of turbine and pump impeller and blade quantity, thus improve transmission efficiency, engine speed is larger, then the moment acting on turbine is also larger.
Accompanying drawing explanation
Fig. 1 be the structure of hydraulic couplers of the present invention as shown in Figure 1.
Embodiment
As shown in Figure 1, input shaft 2 is installed in pump impeller 1 front portion to hydraulic couplers structure of the present invention, and in pump impeller 1, output shaft 4 is installed at rear portion, output shaft 4 is installed bearing 5 and turbine 6, the number of blade 1-4 sheet fewer than pump impeller of turbine 6.
Working principle:
The pump impeller of hydraulic couplers and turbine form an airtight active chamber that liquid-circulating can be made to flow, and pump impeller is contained on input shaft, and turbine cartridge is on output shaft.When power engine (internal-combustion engine, motor etc.) band driven input shaft rotates, liquid is centrifuged formula pump impeller and throws away.Namely this high-speed liquid promotes turbine and rotates after entering turbine, by the energy transferring that obtains from pump impeller to output shaft.Final liquid returns pump impeller, forms the flowing gone round and begun again.
Hydraulic couplers carrys out transmitting torque by the change producing the moment of momentum that interacts of the blade of liquid and pump impeller, turbine.Its output torque equals input torque and deducts friction torque, so its output torque perseverance is less than input torque.By liquid communication between hydraulic couplers input shaft and output shaft, between working component, there is not rigid joint.
The feature of hydraulic couplers is: can eliminate shock and vibration; Output speed is lower than input speed, and the speed discrepancy of diaxon increases with the increase of load; Overload protection performance and starting performance good, during load excessive and stall, input shaft is still rotatable, the unlikely damage causing power engine; When load decreases, output shaft rotating speed increases until close to the rotating speed of input shaft.
The transmission efficiency of hydraulic couplers equals output shaft rotating speed and is multiplied by the ratio that output torque (output power) and input shaft rotating speed are multiplied by input torque (input power).Higher efficiency can be obtained when the rotating ratio of general hydraulic couplers nominal situation is more than 0.95.The characteristic of hydraulic couplers because of active chamber different and variant from the shape of pump impeller, turbine.As the oily emptying by hydraulic couplers, Coupler is just in disengaged condition, can play clutch.
The present invention is described by embodiment, and those skilled in the art know, without departing from the spirit and scope of the present invention, can carry out various change or equivalence replacement to these characteristic sum embodiment.In addition, under the teachings of the present invention, can modify to adapt to concrete situation and material to these characteristic sum embodiment and can not the spirit and scope of the present invention be departed from.Therefore, the present invention is not by the restriction of specific embodiment disclosed herein, and the embodiment in the right of all the application of falling into belongs to protection scope of the present invention.
