Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated: present embodiment is being to implement under the prerequisite with technical solutions of the utility model; provided detailed mode of execution and concrete operating process, but protection domain of the present utility model is not limited to following embodiment.
As shown in Figure 1, present embodiment comprises: outer cylinder body 1, left outer piston 2, left inner carrier 3, gearshift axle 4, gearshift shifting block 5, right outer piston 6, right inner carrier 7, wherein: outer cylinder body 1 comprises the left chamber 1a and the right chamber 1b of two symmetrical configuration, the left chamber 1a of outer cylinder body 1 and 1b inside, right chamber are symmetrical arranged left outer piston 2 and right outer piston 6 respectively, left side outer piston 2 and right outer piston 6 inside are provided with left inner carrier 3 and right inner carrier 7 respectively, gearshift axle 4 is arranged between left inner carrier 3 and the right inner carrier 7, and gearshift shifting block 5 is pinned at gearshift axle 4 centers;
Described outer cylinder body 1 is respectively equipped with left oil transportation mouth c above left chamber 1a and right chamber 1b and right oil transportation mouth d is used for circulation control fluid;
The limit position that described outer cylinder body 1 inside is positioned at left outer piston 2 and right outer piston 6 is respectively equipped with the first left limit step e and the first right limit step f;
The limit position that described left outer piston 2 and right outer piston 6 inside are positioned at left inner carrier 3 and right inner carrier 7 is respectively equipped with the second left limit step g and the second right limit step h.
As shown in Figure 2, the operation of advancing right gear of present embodiment is as follows: the logical pressure oil of cylinder body left side chamber 1a, the logical oil return of right chamber 1b (oil pressure is zero), left side outer piston 2 is not moved by the restriction of limited step, and left inner carrier 3 left sides produce thrust to the right, this thrust promotes left inner carrier 3, gearshift axle 4, gearshift shifting block 5 and right inner carrier 7, right outer piston 6 and moves right together, until entering right gear;
As shown in Figure 3, the operation of moving back neutral of present embodiment is as follows: when the supposition initial position is in the right gear, to about two chamber 1a and 1b infeed pressure oil simultaneously, the thrust that chamber, left side 1a pressure oil only produces left at left inner carrier 3, and right chamber 1b pressure oil is in right inner carrier and outer piston generation thrust to the right, because inside and outside two pistons in the right are simultaneously stressed, thrust greater than the generation of left side inner carrier, so, left side inner carrier 3, gearshift axle 4, shifting block 5 and right inner carrier 7 and right outer piston 6, to left movement, right outer piston 2 is subjected to the restriction of cylinder body limited step no longer to continue motion after arriving neutral gear position always, also no longer exchange gear shaft generation thrust left, the gearshift axle at this time is subjected to a pair of equal and opposite in direction that left and right sides inner carrier produces, direction opposite effect power, make a concerted effort is zero, gearshift axle gearshift shifting block is accurately positioned in neutral gear position with stop motion.
