Had set forth in order to make the Pneumatic power fluid-control type clutch automatic control device compact structure front, spatial volume is little, employing is processed pneumatic linear actuator 1, transition oil hydraulic cylinder 4 and is carried out oil hydraulic cylinder 12 on cast iron or Al alloy block, and process passage as required thereon and replace application tube and tracheae, and with one-way valve 5, two-bit triplet proportional flow control valve 6, two-bit triplet pneumatic valve 8,16, No. 1 outlet valve 17 of venting plug and No. 2 outlet valves 19 all be contained in it above, can be described as the integrated of height, this is determined by the installing space restriction.If installing space is unrestricted, worker's pneumatic linear actuator 1, transition oil hydraulic cylinder 4 with carry out oil hydraulic cylinder 12, all can make monomer-type, the available dedicated oil pipe is connected with tracheae between various cylinder bodies and the various valves, has replaced the passage connection.
Pneumatic power fluid-control type clutch automatic control device has solved that pure pneumatic clutch control system volume is big, low-response, technical problem that control accuracy is low, localized design problems such as the installation of clutch sensor and system's repairing have been solved simultaneously, and clutch separation and joint be decomposed into two independently processes, evaded the influence of pneumatic element damping, effectively improved position in the engaging process, velocity control accuracy and speed of response the hydraulic control precision.
The working principle of Pneumatic power fluid-control type clutch automatic control device:
Consult Fig. 1 and Fig. 4, the left surface effect of the big piston head of combined piston 3 be the air (6bar) that certain pressure is arranged, the oil pocket of the right flank of the small piston head of combined piston 3 produces is hydraulic oil with certain pressure (6bar * S1/S2).The pressure oil of the small piston head right atrial pressure oil pocket of combined piston 3 and the pressure oil of piston 13 left surface annular oil cavities are connected by an automatically controlled two-bit triplet proportional flow control valve 6.In pneumatic linear actuator 1, push the left surface of the big piston head of combined piston 3 by pressure air, the oil pocket of the right flank of combined piston 3 small piston heads generation pressure oil in the transition oil hydraulic cylinder 4 (6bar * S1/S2), under the situation of not considering two-bit triplet proportional flow control valve and oil duct pressure drop, the piston 13 (under the effect of power S3 * 6bar * S1/S2) of carrying out oil hydraulic cylinder 12 directly drives and separates tappet 14, separate tappet 14 and promote disengaging yoke 18 again, when separation tappet 14 moves right, clutch separation, clutch combination when separating tappet 14 to left movement.The air in pneumatic linear actuator 1 inner piston rod chamber is discharged or is entered by venting plug 16 in the working procedure, and keeping in this chamber is atmospheric pressure all the time.
The separation process of clutch
Clutch disengage process is to be that the pressed gas of 6bar is a power with pneumatic source 9 pressure.ECU (Electrical Control Unit) (TCU) 10 sends instructions to two-bit triplet pneumatic valve 8, P interface and A interface are connected, pressed gas in the pneumatic source 9, enter the pressure chamber of big piston head left surface in the pneumatic linear actuator 1, promote that combined piston 3 moves right and in transition oil hydraulic cylinder 4 oil pocket of the right flank of combined piston 3 small piston heads set up oil pressure (6bar * S1/S2), ECU (Electrical Control Unit) 10 sends instructions to two-bit triplet proportional flow control valve 6, the P interface of two-bit triplet proportional flow control valve 6 and A interface are connected, pressure oil in the transition oil hydraulic cylinder 4 enters into the pressure oil cavity of carrying out oil hydraulic cylinder 12 through two-bit triplet proportional flow control valve 6, on piston 13 left side ring surfaces, form the Driving force that size is S3 * 6bar * S1/S2, affact on the disengaging yoke 18 through separating tappet 14, separate tappet 14 and move right, disengaging yoke 18 is swung to the right and is made clutch separation.In this process, core bar when separation tappet 14 moves right in the displacement transducer 11 also together moves right, position signal according to displacement transducer 11 feedbacks, form the closed loop control system of clutch separation, flow by control two-bit triplet Proportional valve 6, can make piston 13 be parked in any one position, even clutch is parked on any one position, thus the separating rate of solenoidoperated cluthes and position.
After the separation process of clutch finishes, ECU (Electrical Control Unit) 10 sends instructions and makes 8 outages of two-bit triplet pneumatic valve, P interface and A interface are obstructed, A interface and T interface are connected, the pressure chamber in big piston head left side and atmosphere are connected in the steam-operating cylinder 1, pressure in its chamber is identical with barometric pressure, this moment, combined piston 3 was moved to the left in the effect of return spring 2, form certain pressure reduction in the transition oil hydraulic cylinder 4 and between atmosphere, this moment, one-way valve 5 was opened, hydraulic oil in the lubricating cup 7 flow into to be and cross oil hydraulic cylinder and finish repairing for 4 li, for next working procedure is prepared.
The engaging process of clutch
The engaging process of clutch is to be power with the returning place force that is installed in the return spring on the clutch, ECU (Electrical Control Unit) 10 sends instructions and makes 6 outages of two-bit triplet proportional flow control valve, the A interface of two-bit triplet proportional flow control valve 6 and T interface are connected, promptly carry out oil hydraulic cylinder 12 pressure oil cavities and lubricating cup 7 connections, the returning place force of the return spring on the clutch reacts on the disengaging yoke 18, react on the separation tappet 14 by disengaging yoke 18, react on the piston 13 by separating tappet 14, piston 13 is expelled back into lubricating cup with hydraulic oil through two-bit triplet proportional flow control valve 6 to left movement, clutch.According to the position signal of displacement transducer 11 feedbacks, form the closed loop control system of clutch, the flow of control two-bit triplet proportional flow control valve 6 comes solenoidoperated cluthes position and clutch engagement.
