Accompanying drawing explanation
Fig. 1 is structure of the present invention and working principle schematic diagram.
Fig. 2 is the structural representation of electromagnetic brake of the present invention.
Embodiment
The present invention is further described below in conjunction with accompanying drawing and instantiation.
As Fig. 1, hydraulic coupling of the present invention comprises clutch casing 1, is arranged on the clutch housing 2 in clutch casing 1, and be fixedly connected with clutch housing 2 and the input shaft 3 be connected with clutch casing 1 by bearing, input shaft 3 is for being connected with motor.
Hydraulic coupling of the present invention also comprises the output shaft 11 be connected with clutch casing 1 by bearing, and output shaft 11 is for being connected with gearbox.Also spring bearing is provided with, for supporting the inner of input shaft 3 and output shaft 11 in clutch housing 2.Also being provided with in clutch housing 2 can the piston of slippage on input shaft 3, and the side of piston is piston cavity, and opposite side is clutch-plate chamber.Several copper sheets that spline is connected with output shaft 11 and several steel discs be connected with clutch housing inwall by spline are also provided with in clutch housing 2.Between the inner of output shaft 11 and piston, Returnning spring is installed.The hydraulic oil that the power that driven plunger is advanced is carried by input shaft 3 realizes.The power that piston retreats is from Returnning spring.The transmission of moment of torsion leans on the friction of steel disc and copper sheet to realize, and the size of transmitting torque leans on the pressure of the hydraulic oil of control inputs axle 3 conveying to realize.
Gear pump 8 import is connected with fuel tank, and outlet is connected with the import of automatically controlled one-way speed-regulating valve 7 and the import of automatically controlled relief valve 9 respectively.Automatically controlled one-way speed-regulating valve 7 exports and is connected with the first accumulator 6 and two position, three-way electromagnetic change valve 5 respectively.Two other mouth of two position, three-way electromagnetic change valve 5, one connects fuel tank, and another connects the second accumulator 4 and connects clutch piston cavity by input shaft 3.Automatically controlled relief valve 9 is exported and is connected with clutch-plate chamber by output shaft 11.The fluid of automatically controlled relief valve 9 overflow is to steel disc and copper sheet lubrication and dispel the heat.
Hydraulic coupling output shaft 11 is equipped with electromagnetic brake 12 by spline, and electromagnetic brake 12 is connected with transducer 10.The temperature transducer of transducer 10 is connected with fuel tank.
As Fig. 2, electromagnetic brake 12 comprises the brake block 12-1 be connected with output shaft 11 by spline.Electromagnetic brake 12 also comprises the electromagnetic brake housing 12-4 be fixedly connected with clutch casing 1, and electromagnetic brake housing 12-4 is built with coil 12-3, asbestos friction sheet 12-2 and electromagnetic brake Returnning spring 12-5.Asbestos friction sheet 12-2 is fixed on the exterior edge face of coil 12-3 for coordinating with described brake block 12-1, and electromagnetic brake Returnning spring 12-5 installs on output shaft 11.Specifically, on described electromagnetic brake Returnning spring 12-5 one end fixed installation output shaft 11, the other end leans against on described brake block 12-1.
It is below working principle of the present invention.
Close when two position, three-way electromagnetic change valve 5 dead electricity, now input shaft 3 oil circuit is communicated with the second accumulator 4, first accumulator 6, automatically controlled one-way speed-regulating valve 7.The size that clutch combines is controlled by automatically controlled relief valve 9.The working pressure of input shaft 3 oil circuit changes between 0 ~ 2 MPa.Open when two position, three-way electromagnetic change valve 5 obtains electric, now input shaft 3 oil circuit, the second accumulator 4 and the oil circuit between the first accumulator 6 and automatically controlled one-way speed-regulating valve 7 are closed, second accumulator 4, input shaft oil circuit are communicated with fuel tank, second accumulator 4, the pressure release of input shaft 3 oil circuit, under action of reset spring, clutch separation.
When entering shelves gearshift, clutch cohesive process is: first the first accumulator 6 gives clutch piston cavity oil-filled, and the first accumulator 6 is drained the oil simultaneously, and when the first accumulator 6 has been drained the oil, piston cavity is full of oil, and steel disc and copper sheet combine, but now pressure is very little.Then give the first accumulator 6, second accumulator 4 oil-filled by automatically controlled one-way speed-regulating valve 7, in Oil feeding process, piston pressure raises gradually, and the moment of torsion of clutch transmission increases thereupon gradually, and this process is the process of clutch gear-shift buffering.Regulated the length of buffer time by the uninterrupted controlling automatically controlled one-way speed-regulating valve 7, flow is little, and the oil-filled time is long, and flow is large, and the oil-filled time is short.The volume of the first accumulator 6 depends on the size of clutch piston cavity, and the volume of the second accumulator 4 depends on the longest buffer time when automatically controlled one-way speed-regulating valve 7 minimum regime flow.
One-way valve in automatically controlled one-way speed-regulating valve 7 and automatically controlled relief valve 9 cooperatively interact, and realize the different pressures needed for system under same state.As hill start, snowfield gearshift etc., when needing moment of torsion less, regulate pressure to realize by controlling automatically controlled relief valve 9.
When hydraulic coupling is separated, electromagnetic brake 12 obtains electric brake, and the maximum brake weight of electromagnetic brake 12 is according to output torque design when being separated under hydraulic coupling low temperature.When the temperature varies, temperature signal to transducer 10, then is converted signal to voltage signal by temperature transducer, flows to electromagnetic brake 12, when the temperature is low, voltage is high, when temperature height, voltage is low, thus when realizing hydraulic coupling separation, is fallen by the balance of output.When hydraulic coupling in conjunction with time, electromagnetic brake 12 dead electricity, brake block is separated under the effect of electromagnetic brake Returnning spring.
The present invention can realize following various Schema control:
1, enter a grade pattern, namely enter forward gears or reverse gear by neutral gear.
Theoretically, clutch plate working pressure is that the gear higher time is longer according to entering the difference of advance 1,2,3,4,5,6 and reverse gear and different from the time that 0-2 MPa at the uniform velocity changes.Ensure can start to walk on any shelves, start to walk on top grade although do not advocate, top grade also can be started to walk smoothly.
2, shift mode: forward gears rises or falls, different situations buffer time is different.
3, normal braking pattern: in traveling during normal braking, after control gear detects brake signal, send control signal, makes clutch automatically be separated.
4, avenge sky, descending brake mode: can arrange snow sky, a descending brake mode button, under making clutch be in abundant bonding state after pressing this button, when guaranteeing to brake, clutch is not separated.
5, hill start pattern: can arrange a hill start mode button, during hill start, clutch is half separated state, has not only ensured can not slip car but also ensure that motor does not stop working.
6, split pattern forced by clutch: control gear detects the speed of a motor vehicle, and when the speed of a motor vehicle is lower than setting value (when such as the speed of a motor vehicle is too low), posittive clutch is separated, to avoid engine misses.
