Embodiment
Fig. 1 gives the schematic diagram of the pneumatic actuator for speed changer of the present utility model.Shift of transmission final controlling element, comprising cylinder and to be arranged in cylinder can the main piston 202 of back and forth movement, and main piston rod 203 stretches out outside cylinder block, for being flexibly connected the driver part of expection.In the utility model, this pneumatic actuator is specially adapted to the executable operations of shift of transmission.In a kind of desirable embodiment, above-mentioned main piston 202 can rest on three positions in described cylinder block in the same direction, causes the mechanism driven by main piston rod can perform the motion of three kinds of positions or state.For speed changer, the three kind positions of piston in cylinder block correspond respectively to three gears of speed changer.
In order to realize above-mentioned function, the utility model devises a kind of mode of execution, is divided into front air cylinder 101 and rear cylinder 102 by cylinder block, between intercepted by partition wall.Front air cylinder 101 and rear cylinder 102 arrange two gas channels respectively separately, or gas can be made to discharge front and back cylinder by gas channel by insufflation gas in gas channel forwards, backwards cylinder.Wherein main piston 202 is placed in rear cylinder, and piston rod 203 stretches out cylinder outside, for connecting the driver part in expectation.Auxiliary piston 201 is provided with in front air cylinder 101, auxiliary piston rod is through the partition wall intercepting front and back cylinder cavity, utilize auxiliary piston 201 can realize making main piston 202 to stop three positions in the cylinder, and then three kinds of executing states are provided, as shown in Figure 1 to Figure 2.For speed changer, three kinds of states of the execution cylinder of the present embodiment can realize performing an action of a gear of speed changer, two gears and neutral.
It is about solution another technical problem of the present utility model that structure below describes, namely when use above-mentioned can provide speed changer three keep off perform execution cylinder time, how to show current shift information intuitively, and how to judge when whether front gear box is unavailable because of actuator failure.In another embodiment of the present utility model, utilize reasonable Arrangement position transducer can monitor the state of actuator in real time, and then directly draw the shifting state of current variator.This position transducer can be the form of magnetic switch, and corresponding to the reaction magnetic ring on main piston and auxiliary piston, when piston driving magnet ring is through magnetic switch, induction switch meeting feedback piston position information, directly or indirectly passes to operator.Described position transducer is arranged on described cylinder block, the position of induction piston.
Fig. 1 shows a kind of arrangement of the position transducer that the utility model relates to, and arranges 3 position transducers 301,302,303, is arranged in respectively in cylinder block and corresponds to main piston 3 positions in the cylinder.This position transducer can be magnetic switch sensor, main piston is provided with magnet ring 300, when the magnetic sensible switch sensor of the magnet ring 300 on piston through being arranged on cylinder, and sensor feedback signal.Particularly,
For the another kind of arrangement of position transducer, be furnished with 4 position transducers 301,302,303,304, as shown in Figure 2.Wherein first sensor 301 is for feeding back the position of auxiliary piston 201, second and third, four-sensor 302,303,304 arranges position for feeding back main piston 202 successively.Sensor feedback information is as follows: when main piston 202 is positioned at primary importance, the second sensor 302 feedback position information; When main piston 202 is positioned at the second place, first sensor 301 and the 3rd sensor 303 feedback position information simultaneously; When main piston 202 is positioned at the 3rd position, four-sensor 304 feedback position information.Be need to realize by means of auxiliary piston 201 based on the second place of main piston 202 with the arrangement of upper sensor, when first sensor 301 and the 3rd sensor 303 feed back simultaneously, show that current actuating mechanism function well and main piston is in the second place.Otherwise, if first sensor 301 or the 3rd sensor 303 feed back separately, then represent that current final controlling element exists fault, need maintenance.What deserves to be explained is, above sensor arrangement and the set-up mode of feedback information are the structures depending on concrete final controlling element, namely when actuator structure changes, the arrangement of sensor and feedback system also can change accordingly, but do not depart from know-why of the present utility model and original intention.
The feedback information of the sensor can be the mode that light emitting diode is lighted, and can adopt the realizations such as buzzer.When above-mentioned final controlling element is arranged in the gearshift execution component for speed changer on speed changer, current gear can be read easily by the sensor feedback information on final controlling element.
Therefore the utility model additionally provides a kind of speed changer, utilize above-mentioned final controlling element.Comprising control gear, signal connects above-mentioned position transducer, collecting sensor feedback information.Also comprise at least one gas source; At least three gas open-close valves, for controlling described gas source to described cylinder block air inlet or give vent to anger.The piston rod of cylinder main piston connects shift of transmission parts, as selector fork.When main piston rod moves, drive selector fork, make shift fork promote gear and be interconnected, realize gearshift.The position of main piston in cylinder corresponds to a kind of state of selector fork, namely corresponds to a gear of speed changer.Need to further illustrate, signal is connected to the control gear of position transducer, by detecting the piston position information of position sensor feedback, reading current variator gear, feeding back to user interface.User can directly obtain Current vehicle gear situation and whether speed changer is normal.If speed changer is because of actuator failure generation exception, the malposition signal transmission of the sensor feedback that position transducer control gear receives, to full-vehicle control device, is made the response of speed changer exception by car load.
The utility model also provides a kind of vehicle using above-mentioned speed changer, has full-vehicle control device, is connected with above-mentioned biography device control gear, gas open-close valve communication.
