Accompanying drawing explanation
The position transducer of Fig. 1 first embodiment of the invention is arranged schematic diagram;
The position transducer of Fig. 2 second embodiment of the invention is arranged schematic diagram;
Embodiment
Fig. 1 has provided the schematic diagram of the pneumatic actuator for speed changer of the present invention.Shift of transmission final controlling element, comprise cylinder and be arranged in cylinder can back and forth movement main piston 202, main piston rod 203 stretches out outside cylinder block, for being flexibly connected the driver part of expection.In the present invention, 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, and the mechanism that causes being driven by main piston rod can carry out 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 present invention has designed a kind of mode of execution, be about to cylinder block and be divided into front air cylinder 101 and rear cylinder 102, between by partition wall, intercept.Front air cylinder 101 and rear cylinder 102 arrange respectively two gas channels separately, can in cylinder, are filled with gas or make gas discharge front and back cylinder by gas channel forwards, backwards by gas channel.Wherein main piston 202 is placed in rear cylinder, and piston rod 203 stretches out cylinder outside, for connecting the driver part of expectation.In front air cylinder 101, be provided with auxiliary piston 201, auxiliary piston rod is through the partition wall of cylinder cavity before and after intercepting, utilize auxiliary piston 201 to realize and make main piston 202 rest on three positions in cylinder, and then three kinds of executing states are provided, as shown in Figure 1 to Figure 3.Take speed changer as example, and three kinds of states of the execution cylinder of the present embodiment can be realized a gear, two gear and the performing an action of neutral of speed changer.
It is about solving another technical problem of the present invention that structure is below described, above-mentioned when the speed changer execution cylinder that three gears are carried out can be provided when using, how to show intuitively current shift information, and how to judge when whether front gear box is because actuator failure is unavailable.In another embodiment of the present invention, utilize reasonable Arrangement position transducer can monitor in real time the state of actuator, and then directly draw the shifting state when front derailleur.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 process magnetic switch, induction switch can feed back 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 has shown a kind of arrangement of the position transducer the present invention relates to, and arranges 3 position transducers 301,302,303, is arranged in respectively in cylinder block 3 positions in cylinder corresponding to main piston.This position transducer can be magnetic switch sensor, is provided with magnet ring 300 on main piston, when magnet ring 300 processes on piston are arranged at the magnetic sensible switch sensor 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 the position for feeding back main piston 202 successively.Sensor feedback information is as follows: when main piston 202 is positioned at primary importance, and 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 be feedback position information simultaneously; When main piston 202 is positioned at the 3rd position, four-sensor 304 feedback position information.With the arrangement of upper sensor, be that the second place based on main piston 202 need to realize by means of auxiliary piston 201, when first sensor 301 and the 3rd sensor 303 feed back simultaneously, show current actuating mechanism function well and main piston in the second place.Otherwise, if first sensor 301 or the 3rd sensor 303 feed back separately, 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 that depends on concrete final controlling element, 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 invention 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 on speed changer while carrying out member for the gearshift of speed changer, can read easily current gear by the sensor feedback information on final controlling element.
Therefore the present invention also 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 giving 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 interconnect, realize gearshift.The position of main piston in cylinder be corresponding to a kind of state of selector fork, corresponding to a gear of speed changer.Need to further illustrate, signal is connected in the control gear of position transducer, and the piston position information of feeding back by detection position sensor, reads current transmission gear, feeds back to user interface.User can directly obtain when vehicle in front gear situation and speed changer whether normal.If speed changer is abnormal because of actuator failure generation, the malposition signal of the sensor feedback that position transducer control gear receives passes to car load control gear, by car load, makes the abnormal response of speed changer.
The present invention also provides a kind of vehicle that uses above-mentioned speed changer, has car load control gear, is connected with above-mentioned biography device control gear, gas open-close valve communication.
The content that this specification is not described in detail belongs to the known prior art of professional and technical personnel in the field.
