Table 1
be moved to the left the most left A position, namely interchangeable to neutral gear position between 5 gears and 6 gears, if this moment, continuation is inflated in the 3rd cavity by the 3rd gas channel 7, also be filled with simultaneously the gas with the 3rd gas channel 7 uniform pressure in the first cavity by the first gas channel 3, control the second gas channel 5 and the 4th gas channel 8 exhausts, because the internal diameter of the first cavity gear-selecting cylinder of living in is larger, the first block selecting slide block 2 and piston rod 4 will move right together, until the first block selecting slide block 2 moves to the precalculated position with stop motion, please refer to Fig. 3, in Fig. 3, the first block selecting slide block 2 moves to the step place of two Different Diameter endoporus with stop motion, piston rod 4 moves right continuing under effect of inertia, this moment the first cavity side piston rod 4 the stressed area that only depends on piston rod 4, the lifting surface area in left side in sectional area by appropriate design piston rod 4 and the 3rd cavity, piston rod 4 is with stop motion in place, piston rod 4 arrives the B position at this moment, neutral gear position between namely 3 gears and 4 keep off.
Control the gas that the first gas channel 3 and the 4th gas channel 8 pass into uniform pressure, when the second logical atmosphere of gas channel 5 and the 3rd gas channel 7 exhaust, piston rod 4 moves right continuing, when piston rod 4 contacts with piston 9, under the pressure of two ends gas, piston rod 4 arrives stop motion in the C position, i.e. the neutral gear position of 1 gear and 2 gears.Only need each gas channel to be set to following state: the first gas channel 3 air inlets, second and third gas channel is communicated with atmosphere, the 4th gas channel 8 exhausts.
The second cavity is communicated with atmosphere all the time by the second gas channel 5 in this embodiment, and the conversion of the working staties such as the turnover gas of other three gas channels can realize by control valve.
In present embodiment in pneumatic block selecting actuator executive component quantity fewer, user cost is lower, and control flow is relatively simple, especially this mechanism structure is fairly simple, takes up room smaller, satisfies the car load design requirement.
On the basis of upper the first mode of execution, can increase control valve the working state of the second gas channel 5 is controlled, and then improve the rapidity of block selecting, below provided two kinds of embodiments, shown in being described in detail as follows.
Please refer to table 2, table 2 is the working state of each gas channel of gear-selecting cylinder in the second embodiment.
Table 2
In the second embodiment, when changing to neutral A, B, C position, the working state of each gas channel of gear-selecting cylinder is identical with working state in the first embodiment, difference is, when changing to neutral gear position corresponding to the R that reverses gear, the second gas channel 5 air inlets, the 3rd gas channel 7 is communicated with atmosphere, the first gas channel 3 air inlets, the 4th gas channel 8 exhausts.
Table 3
The third embodiment is further to improve on the second embodiment, has further improved the rapidity of block selecting.
Please refer to table 3, table 3 is the working state of each gas channel of gear-selecting cylinder in the third embodiment.
In the third embodiment, when changing to neutral A, B, D position, the working state of each gas channel of gear-selecting cylinder is identical with working state in the second embodiment, difference is, when the neutral gear position C that changes to 1 gear and 2 gear centres, the second gas channel 5 also needs air inlet, and other gas channel working staties are constant.
Control valve in the respective embodiments described above can be solenoid valve, specifically can use two-position three way magnetic valve.
In the respective embodiments described above, pneumatic block selecting actuator also comprises can transmission system, and the detection part on gear-selecting cylinder is electrically connected to the controller of transmission system, and the controller of transmission system is by the position of the testing signal judgement gear-selecting cylinder of detection part.
This set-up mode need not to increase other controlling componenies, and directly the Integrated design control program gets final product on the basis of existing technology, and user cost is fairly simple, and it is convenient to control.
Need to prove, left and right orientation used herein pronoun is with the relative position between each parts of gear-selecting cylinder definition in Fig. 2 and Fig. 3, is only simple for the description technique scheme, can not limit the protection domain of this paper.
The technique effect of the gear-selecting cylinder in the technique effect of above-mentioned pneumatic gear selection mechanism and above-mentioned arbitrary mode of execution is basic identical, does not repeat them here.
The otherwise data of pneumatic gear selection mechanism is same as the prior art, please refer to prior art.
Above a kind of gear-selecting cylinder provided by the present invention and pneumatic block selecting actuator are described in detail.Used specific case herein principle of the present invention and mode of execution are set forth, above embodiment's explanation just is used for helping to understand method of the present invention and core concept thereof.Should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention, can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection domain of claim of the present invention.
