Abstract
This invention provides a self loop pump type dynamic force transmitter that can transmit dynamic force. it mainly relates to all kinds of clutches, transmission and brake and other assembly product. The technique plan is that liquor entrance and exit ends of hydraulic pump 1 are directly connected by a cast channel 2, control valve 6 is set at channel central part and is driven by electrical machine 7, inside the self loop system is full of liquor. When control valve 6 is started, pump axis 5 can free rotate relative to pump block 1, and when valve 6 is closed, liquor in channel 2 meet maximum resistance and pump 5 can not move. The value of resistance of self loop system can be controlled by adjusting position of control valve 6, so pump axis 5 and pump block 1 can be placed all kinds of relative states. Different applications and different capability clutch, brake and non-stage transmission and other dynamic force transmitting product can be designed and made by using pump axis 5 and pump block 1 shell as the two action ends of dynamic force transmitting.
Description
Invention field:
The present invention relates to the power transmission member in all kinds of electromechanical equipments, specially refer to various clutches, speed changer, brake assembly.
Background technique:
At present, in the known all kinds of electromechanical equipments, extensively exist and a large amount of clutch, speed changer, breaks that use all exist various heterogeneitys, in various degree serious even to ordering defective, now be described below respectively:
One product with friction mode work
1 exists the consumption of friction material, and also there is fuel consumption in clutch.
2 bear the overload and impact capacity poor.
3 stepless speed variator gear ratio inaccuracy, slewing range is little.Driving belt is fragile, can't bear big load and impact force
The person, equipment accident take place in the easy heating burnout of 4 brake bushs.
Two products with the work of gear mode:
1 when using as clutch, and impact, fragile, the generally only suitable low speed transmission of gear are arranged during joint.
2 when using as speed changer, can not stepless change, and slewing range is little, has gear abrasion consumption and impact failure, consumes oil plant.
3 complex structures, component kind and quantity are all many, need join operating device, volume is big, weight is big, use and operate equal inconvenience.
Three products with electromagnetic mode work:
Slip type magnetic clutch bearing capacity is poor, volume is big, transmitting torque is little, low, the easy heating of efficient, big, the consumed power of volume when slow in one's movements, low speed and unfavourable balance are big.
Four their common defects are:
1 consumes machine thing oil plant, user cost height.
2 complex structures, the cost of production height.
3 is fragile, and maintenance, the maintenance work amount is big, the expense height, and Utilization ratio is low.
Summary of the invention:
The purpose of this invention is to provide a kind of self circulating pump type power transmitter, to overcome above-mentioned existing defective.And with its excellent performance replacement the said goods.
Technological scheme of the present invention is: a kind of self circulating pump type power transmitter is made of oil hydraulic pump, connecting pipe and control valve, and pipe ends directly is communicated with the liquid entrance two ends of oil hydraulic pump, and control valve is arranged on the stage casing of pipeline, is operated by Electric Machine Control.Be full of liquid in the self-circulation system.Constitute the controlled self-circulating pump of a damping, its pump case and transmission shaft are as two effect ends of transmission of power.This device can be realized stepless change, transmission clutch and braking function fully.And having simple in structurely simultaneously, volume is little, in light weight, efficient is high and big or small unrestricted, the advantage such as user cost is low of transmitting torque.
According to such scheme, the present invention also has following measure: pressure transducer is set to measure torque in the hyperbaric chamber of oil hydraulic pump.At clutch end revolution detector is set, works by stepper motor driver drive stepping motor operation control valve.Thereby be equipped with microprocessing systems and realize intelligent control.Its outside can be provided with the various box body of protection, supporting and installation effect as required.
Description of drawings
Fig. 1 is a hydraulic work schematic diagram of the present invention
In the accompanying drawing 2: the 1-pump housing, 2-connecting pipe, 3-connection shaft, 4-protecgulum, 5-pump shaft, 6-control valve, 7-motor.。
Below in conjunction with accompanying drawing 2 and embodiment the technology of the present invention is described further:
Operation principle: if the connecting axle 3 that the housing of the pump housing 1 is connected and fixed is as the input of power, pump shaft 5 is as clutch end, then its specific works principle:
1 when control valve 6 (being driven by motor 7) is closed, the flow q=0 of interface channel 2 interior liquid mediums, and according to calculation of hydraulic pressure formula q=vn, V is discharge capacity, and n is rotating speed, and rotation speed n is zero as can be known, and namely pump shaft 5 is inactive state with respect to the pump housing 1. Be equivalent to firmly connect transmission, pump shaft 5 has Maximum speed output.
2 when control valve 6 standard-sized sheet, and the import and export of hydraulic pump all do not have pressure, according to the Po=p.q/60 of calculation of hydraulic pressure formula, and Po power output, p Be pressure, when pressure was zero, then power output was zero. This moment, pump shaft 5 was state free to rotate with respect to the pump housing 1, and transmission of power is in branch From state, rotating speed is zero.
3 when control valve is closed gradually, and the damping of the working fluid in the circulatory system increases gradually, and the outlet end pressure p is driven to maximum gradually by mould, and the output power of its pump shaft 5 also increases to maximum gradually by zero.The output speed of pump shaft 5 is also by zero synchronization that increases to gradually with the pump housing 1, so this structure can realize clutch, braking and three functions of speed change fully, and three functions are integrated in one.
Embodiment:
As Fig. 2, control valve 6 is installed in the middle part of pipeline 2, and the two-port of pipeline 2 is communicated with respectively with the liquid entrance two ends of the pump housing 1, and the coupling shaft 3 usefulness screws and the pump housing 1 are fixing, and its axial position is concentric with pump shaft 5, and the axle of motor 7 is connected with the screw mandrel of control valve 6.
Beneficial effect:
1 volume is little, and is in light weight, simple in structure, existing technical maturity, material and cheap for manufacturing cost.
2 uses are easy to operate.
3 is not fragile, and the life-span is long, keeps in repair, maintains simply, stable work in work.
4 consume atomicly comparatively speaking, and cost of use is low.
5 transmission efficiency height, torque is big.
6 can realize the gamut stepless change, and friction-free braking has been cancelled clutch.
7 easily realize full intellectualized control.
Particularly unrestricted and do not have characteristics of neutral transition completely without the level speed change according to transmitting torque size, can be applied in heavy armored vehicle fully, on tank and the helicopter, has very military significance, on the other hand more because being extensive use of of power transmission member, make this invention have very huge application market, especially in traffic, the all trades and professions of heavy industry and light industry can be brought into play its huge effect and incomparable superiority, can save great amount of manpower, material resources, financial resources, the performance of raising equipment and efficient significantly reduce user's input cost and cost of use.Therefore think personally that this invention can produce very big economic benefit and social benefit.Its concrete benefit has to be assessed.
