[accompanying drawing explanation]
Fig. 1 is structural representation of the present utility model.
[embodiment]
Refer to shown in Fig. 1, a kind of AMT break of the utility model, comprises piston mechanism, friction mechanism and resetting-mechanism.
Piston mechanism comprises controller, solenoid valve and piston 3; Piston 3 is arranged in the cylinder forming between clutch housing 1 and case of transmission 7; Controller connected electromagnetic valve, solenoid valve connects air inlet/outlet 2 by gas circuit, and air inlet/outlet 2 is arranged on clutch housing 1 and is communicated with the enclosed cylinder between clutch housing 1 and piston 3.
Friction mechanism comprises multiple steel discs 4 and friction plate 5; Case of transmission 7 is stretched out in the end of jack shaft 8, and multiple friction plates 5 are connected with the end of jack shaft 8 by spline; Steel disc 4 is embedded into (not shown) in the multiple grooves in clutch housing 1 by the multiple projections of circumferencial direction, connects together with clutch housing; The both sides of friction plate 5 are equipped with steel disc 4; Steel disc 4 and friction plate 5 are held between piston 3 and dividing plate 6, and dividing plate 6 is arranged in case of transmission 7 sides.
Resetting-mechanism comprises ejector pin 11 and spring 9; The spindle nose of jack shaft 8 is provided with endoporus, and ejector pin 11 can be free to slide in the endoporus of jack shaft 8 spindle noses, and ejector pin 11 inner hollow are enclosed within on spring 9.Between piston 3 and spring 9, interact by straight pin 12 and ejector pin 11, straight pin 12 is fixed together with piston 3.
In the time that speed changer need to upgrade, first speed changer is plucked to neutral gear.Then controller is to solenoid valve electrical signal, solenoid valve is opened, pressurized air enters in the cylinder of clutch housing 1 by solenoid valve and air inlet/outlet 2, promote piston 3, piston 3 overcomes the spring force of spring 9, and pressing friction sheet 5 and steel disc 4, steel disc 4 right sides are pressed on case of transmission 7 by dividing plate 6.Friction plate 5 and steel disc 4, because the impacting force of piston 3 produces frictional force, so just can carry out braking deceleration to the speed changer part with jack shaft 8 and together with being engaged with.In the time reaching deceleration requirement, solenoid valve power-off commutation, gas gas in the jar communicates with atmosphere.At this moment, spring 9 will promote piston 3 and promote left to reset, and just gas in the jar can be discharged, and eliminate braking force simultaneously.
