Description
[technical field]
The utility model relates to the speed changer technical field, particularly a kind of automatic clutch actuator.
[background technique]
Automatic speed changer for machine (AMT) becomes at present one of research and development focus of automatic transmission both at home and abroad with himself characteristic.The control of clutch is technological difficulties of AMT system.In order to realize the automatic control of clutch, automatically controlled pneumatic-typed, electric-controlled hydraulic formula and full electric-controlled type clutch have successively appearred.Automatically controlled pneumatic-typed clutch receives the air pressure transmission position to put control, speed controlling difference etc., is difficult to realize the accurate control of clutch cohesive process position.Electric-controlled hydraulic formula clutch can satisfy the requirement of vehicle starting process to clutch; But hydraulic power must be arranged, and the required precision of hydraulic element processing is very high, processing technology is complicated; High to performance requirements such as oil quality, sealing and antipollutions, it is bigger etc. to go back temperature influence.Full electric-controlled type clutch is driven by direct current generator, with comparing of electrically controlled and hydraulically, have simple in structure, control flexibly, characteristics such as strong to the adaptation of environment, technology is simple, and cost is low, and energy consumption is little; Shortcoming is that the execution action of motor does not have hydraulic system accurate, and selects the action of gear shift slower, and output power is less.
[model utility content]
The purpose of the utility model provides a kind of automatic clutch actuator, in conjunction with air pressure and hydraulicdriven pluses and minuses, air pressure and hydraulic control is combined, and realizes the automatic control of clutch.
To achieve these goals, the utility model adopts following technological scheme:
A kind of automatic clutch actuator comprises cylinder, oil hydraulic cylinder, piston, air pressure valve and computer; Piston comprises first piston, second piston and piston rod, and first piston is positioned at cylinder, and second piston is positioned at oil hydraulic cylinder; Piston rod one side connects the first piston and second piston, and opposite side connects clutch; Cylinder is separated into cylinder chamber, a left side and the right chamber of cylinder by first piston; Oil hydraulic cylinder is separated into oil hydraulic cylinder chamber, a left side and the right chamber of oil hydraulic cylinder by second piston; Chamber, a cylinder left side connects air pressure valve, and air pressure valve connects source of the gas and computer; The right chamber of cylinder is provided with exhaust port; Be connected with the one-way throttle valve that throttle valve and one-way valve parallel connection are combined between the left chamber of oil hydraulic cylinder and the right chamber; Computer connects throttle valve and one-way valve; The clutch place is provided with the sensor that detects the clutch displacement, and this sensor connects computer.
Preferably, the right chamber of oil hydraulic cylinder is connected with lubricating cup.
With respect to existing technology; The utlity model has following advantage: the utility model actuator combines air pressure and hydraulicdriven pluses and minuses; Utilize truck that the characteristics of gas pressure source are arranged, proposed a kind of dynamic hydraulic combined clutch actuating mechanism, both utilized the former car energy; Need not install hydraulic power additional, solve the problem of air pressure control relative difficult simultaneously; This mechanism adopts the mode of two active chamber series connection of gas-liquid, and the separation through air pressure realization clutch utilizes throttle valve to carry out the control of cohesive process.Its cost is low, utilizes the power source of former car, and pneumatic control valve is few etc., and technological requirement is simple relatively; The control difficulty is lower, the accurate control of the easy realization position of hydraulic pressure.
[description of drawings]
Fig. 1 is the structural representation of the utility model.
[embodiment]
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
See also shown in Figure 1ly, a kind of automatic clutch of the utility model actuator comprises cylinder, oil hydraulic cylinder and piston, and piston comprises first piston, second piston and piston rod; First piston is positioned at cylinder, and second piston is positioned at oil hydraulic cylinder; Piston rod one side connects the first piston and second piston, and opposite side connects clutch; Cylinder is separated into cylinder chamber, a left side and the right chamber of cylinder by first piston; Oil hydraulic cylinder is separated into oil hydraulic cylinder chamber, a left side and the right chamber of oil hydraulic cylinder by second piston; Chamber, a cylinder left side connects air pressure valve, and air pressure valve connects source of the gas and computer; The right chamber of cylinder is provided with exhaust port; Be connected with the one-way throttle valve that throttle valve and one-way valve parallel connection are combined between the left chamber of oil hydraulic cylinder and the right chamber; Computer connects throttle valve and one-way valve; The clutch place is provided with the sensor that detects the clutch displacement, and this sensor connects computer; The right chamber of oil hydraulic cylinder is connected with in order to reveal the lubricating cup that the back replenishes hydraulic oil at hydraulic oil.
The concrete working procedure of this actuator: in the clutch disengage process; Open through the computer control air pressure valve, source of the gas and chamber, a cylinder left side are connected, and the right chamber of cylinder is through the outside exhaust of exhaust port; Hydraulically-controlled one-way valve work; Pressurized air gets into cylinder left side chamber promotion piston and moves right, and the hydraulic oil in the right chamber of oil hydraulic cylinder flows to chamber, an oil hydraulic cylinder left side through one-way valve under the effect of piston, realize that clutch separates fast; In the clutch cohesive process, the computer control air pressure valve cuts out, cylinder chamber, a left side and atmosphere; The right chamber of cylinder is through exhaust port air inlet in the chamber; Hydraulically-controlled one-way valve is closed, and sensor is to the Displacement Feedback of clutch to computer, under the effect of the diaphragm spring of clutch; Computer is controlled the hydraulic oil flow in chamber, a hydraulic pressure left side to the right chamber of hydraulic pressure according to the size of driver's intention control throttle valve opening, thus the displacement of solenoidoperated cluthes.
