Abstract
The utility model discloses an open-ring electric control pneumatic clutch, which comprises a pedal signal sensor (14) and a clutch casing (1), wherein the pedal signal sensor (14) is connected with a controller (12); an air cylinder (5) and a slave valve (2) with an air inlet pipe (3) and an exhaust pipe (4) are fixed on the casing (1); a pipeline (6) is arranged between the air cylinder (5) and the slave valve (2). The utility model is characterized in that a stepping motor (10) is fixedly connected to an air cylinder piston (11); a rotating shaft (8) of the stepping motor is connected with a valve rod (13) of the slave valve by a gear (9) and a gear rack (7); the stepping motor (10) is connected with the controller (12). The utility model has the characteristics of simple installation, low cost and simple control.
Description
Technical field
The utility model relates to a kind of automobile clutch control gear, especially heavy automobile clutch control gear.
Background technique
Traditional heavy automobile clutch control gear has mechanical type to handle the gas power-assisted usually and hydraulic type is handled two kinds of gas power-assisteds, it is several that wherein the former is divided into linkage type, drag-line etc. again, any mechanial control device no matter, for narrow and small vehicle environmental, connect and all compare difficulty, then there is leakage of oil in the latter, defectives such as hydraulic system air inlet.Along with science and technology development, electric control mechanical type automatic speed variator becomes development trend, and electric control clutch is its critical component.Closed loop control is all adopted in the control of electric control clutch in the past, with the position of sensor acquisition clutch by controlling the motion that various solenoid valves come solenoidoperated cluthes, because the needs of automobilism environment and control accuracy, meet the demands sensor and solenoid valve costs an arm and a leg usually, increases greatly compared with mechanical type and hydraulic type cost like this.
Summary of the invention
The purpose of this utility model provides a kind of open loop electro-pneumatic clutch, and it has, and installation is simple, cost is low, control is simple, be convenient to be integrated into the electric control mechanical type automatic speed variator system.
The purpose of this utility model is achieved through the following technical solutions, it comprises clutch housing, pedal signal sensor, the pedal signal sensor links to each other with controller, the servo valve that on clutch housing, is fixed with cylinder and has inlet and outlet pipeline, be provided with pipeline between cylinder and the servo valve, it is characterized in that: be fixedly connected with stepper motor on cylinder piston, the stepper motor rotating shaft is connected with the servo valve valve rod by gear, tooth bar, and this stepper motor links to each other with controller.
The utility model is owing to adopt technique scheme, only on traditional clutch gas servo control-unit basis, increase by a stepper motor, compare with the closed loop electric control clutch, save the displacement transducer and the solenoid valve that detect the piston motion, therefore have the characteristics that control is simple, cost is low.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the accompanying drawing, 1-clutch housing, 2-servo valve, 3-suction tude, 4-outlet pipe, 5-cylinder, 6-pipeline, 7-tooth bar, 8-motor shaft, 9-gear, 10-stepper motor, 11-piston, 12-controller, 13-servo valve valve rod, 14-pedal signal sensor.
Embodiment
That the utility model is described in further detail is as follows below in conjunction with accompanying drawing:
The utility model comprises pedal signal sensor 14, clutch housing 1, pedal signal sensor 14 links to each other with controller 12, the servo valve 2 that on housing 1, is fixed with cylinder 5 and has suction tude 3, outlet pipe 4, be provided with pipeline 6 between cylinder 5 and the servo valve 2, be fixedly connected with stepper motor 10 on cylinder piston 11, stepper motor rotating shaft 8 is connected with servo valve valve rod 13 by gear 9, tooth bar 7, and this stepper motor 10 links to each other with controller 12.As shown in the figure, in a sampling period when controller 12 by pedal signal sensor 14 detect that pedal moves downward apart from the time, controller 12 control control step motors 10 are by gear 9, tooth bar 7 pulling servo valve valve rods 13 move right corresponding distance, beginning because servo valve 2 valve bodies and clutch are connected valve body motionless, servo valve 2 air inlet open, cylinder 5 air inlet pistons 11 promote clutch separation left, piston 11 itself drives motor body 10 again to left movement, and servo valve valve rod 13 motion this moment be the resultant motion that drives the own motion left of the motion to the right of tooth bars 7 and motor 10 with motor shaft 8.When moving to the displacement of instruction, step motor shaft 8 driven gears 9, tooth bar 7 just do not continue to move right, because piston 11 drives motor body 10 and itself moves, compensated the motion of motor shaft 8 drive servo valve valve rods 13 by this machine feedback, when motor no longer moves, piston 11 drives motor body 10 and servo valve valve rod 13 is closed the servo valve suction port to left movement, and piston 11 no longer continues motion.Conversely in like manner.So just realized the control of clutch and pedal.The utlity model has the characteristics that control is simple, cost is low.
