Description of drawings
Fig. 1 is structure of the present invention and working principle schematic representation.
Embodiment
Further describe the present invention below in conjunction with accompanying drawing and instantiation.
Such as Fig. 1, the present invention includes wet-type hydraulic clutch, described wet-type hydraulic clutch comprises clutch casing 1, be installed in from
Close the clutch housing 2 in the device casing 1, the input shaft 3 that is fixedly connected with clutch housing 2 and is connected with the clutch casing by bearing, input shaft 3 is for being connected with motor.Also comprise the output shaft 9 that is connected with clutch casing 1 by bearing.Output shaft 9 is used for being connected with gearbox.In clutch housing 2, also be provided with spring bearing, be used for supporting the inner of input shaft 3 and output shaft 9.
In clutch housing 2, also be provided with can slippage on input shaft 3 piston, in clutch housing 2, also be provided with several copper sheets that are connected with output shaft 9 by spline and several steel discs that are connected with clutch housing 2 inwalls by spline.Between the inner of output shaft 9 and the piston Returnning spring is installed.The hydraulic oil that the power that driven plunger is advanced is carried by input shaft 3 is realized.The power that piston retreats is from Returnning spring.Transfer of torque is realized by the friction of steel disc and copper sheet; The size of transmitting torque realizes by the pressure of the hydraulic oil that control inputs axle 3 is carried.
The present invention also comprises two position, three-way electromagnetic change valve 4, and its first interface is connected with input shaft 3, and second interface is connected with inner chamber as the clutch casing 1 of fuel tank, and the 3rd interface is connected with respectively accumulator 5 and automatically controlled one-way speed-regulating valve 6.The filler opening of automatically controlled one-way speed-regulating valve 6 is connected with respectively gear pump 7 and automatically controlled precursor overflow valve 8.The oil outlet of automatically controlled precursor overflow valve 8 is connected with output shaft 9, is provided for steel disc and copper sheet heat radiation, lubricated hydraulic oil by output shaft 9 to the inner chamber of clutch housing 2.
Close when two position, three-way electromagnetic change valve 4 dead electricity, this moment, input shaft 3 oil circuits were communicated with accumulator 5 and automatically controlled one-way speed-regulating valve 6, the clutch combination, and the combination force size is by automatically controlled precursor overflow valve 8 controls.The working pressure of input shaft 3 oil circuits changes between the 0-2 MPa.Two position, three-way electromagnetic change valve 4 open when electric, this moment input shaft 3 oil circuits with accumulator 5 and automatically controlled one-way speed-regulating valve 6 between the oil circuit shutoff, input shaft 3 oil circuits are communicated with fuel tank, input shaft 3 oil circuit pressure releases, clutch separation under action of reset spring.
When advancing shelves and gear shift, the clutch cohesive process is: at first accumulator 5 gives the clutch plunger chamber oil-filled, and accumulator 5 is drained the oil simultaneously, and when accumulator 5 discharged oil, piston cavity was full of oil, steel disc, copper sheet combination, but pressure is very little.Then give accumulator 5 oil-filled by automatically controlled one-way speed-regulating valve 6, piston pressure raises gradually in the oil-filled process, and the moment of torsion that clutch transmits increases thereupon gradually, and this process is exactly the process of clutch shift buffering.By the length that the uninterrupted of controlling automatically controlled one-way speed-regulating valve 6 is regulated buffer time, the little oil-filled time of flow is long, and the large oil-filled time of flow is short.
One-way valve and automatically controlled precursor overflow valve 8 in the automatically controlled one-way speed-regulating valve 6 are worked in coordination, and are implemented in the required different pressures of system under the same state.Such as half way up the mountain starting, snowfield gear shift etc., need moment of torsion hour, can regulate pressure and realize by controlling automatically controlled precursor overflow valve 8.
The present invention also comprises the control gear for control two position, three-way electromagnetic change valve 4, automatically controlled one-way speed-regulating valve 6 and automatically controlled precursor overflow valve 8.Described control gear is controlled two position, three-way electromagnetic change valve 4, automatically controlled one-way speed-regulating valve 6 and automatically controlled precursor overflow valve 8 according to the rotating speed of gear shift, gear initial position, in-position, motor, emulation mode etc.
The present invention can realize following various pattern control:
1, advances a grade pattern, namely enter forward gears or reverse gear by neutral gear.
Theoretically, the clutch plate working pressure is to advance 1,2,3,4,5,6 and the difference of reverse gear and difference according to entering from the time that the 0-2 MPa at the uniform velocity changes, and the higher time of gear is longer.Guarantee on any shelves, can both start to walk, do not start to walk although do not advocate at top grade, on top grade also can start to walk smoothly.
2, shift mode: forward gears rises or falls, different situations buffer time difference.
3, normal braking pattern: when travelling middle normal braking, after control gear detects brake signal, send control signal, clutch is separated automatically.
4, snow day, descending brake mode: a snow day, descending brake mode button can be set, clutch be under the abundant bonding state after pressing this button, clutch does not separate when guaranteeing to brake.
5, half way up the mountain plays step mode: half way up the mountain starting mode button can be set, and clutch is half separation state during the half way up the mountain starting, has not only guaranteed can not slip car but also guarantee that motor is flame-out.
6, clutch is forced split pattern: control gear detects the speed of a motor vehicle, and when the speed of a motor vehicle is lower than setting value (crossing when low such as the speed of a motor vehicle), posittive clutch separates, to avoid engine misses.
