The lower end for sliding pin 4 is tooth type structures, and the tooth type structures match with the serrate slot opened up on shift fork universal driving shaft 13
Close.
Operation principle：
When scope gear cylinder is in low gear position, as shown in Figure 1：
Pin 4 is slided in the presence of the power of spring 5, is stuck in the groove of shift fork universal driving shaft 13, slides the external cylindrical surface of pin 4
Groove and shift fork axle interlocking block 12, interlocking steel ball, interlocking plunger center alignment.Now any gear of main tank can put into gear, it is illustrated that
So that 4/5 gear shift fork axle 8 is put into gear as an example, 4/5 gear shift fork axle 8 is moved, and the second interlocking steel ball 9 of axle side is extruded from its side channel, the
Two interlocking steel balls 9 promote its a series of interlocking plunger in left side, the first interlocking steel ball 7 and shift fork axle interlocking block 12, until Far Left
Shift fork axle interlocking block 12 insertion slide pin 4 groove in；I.e. odd-side is in low gear position, and main tank can put into gear.Self-locking spring
Under compressive state on self-locking steel ball, when main tank is shifted gears, self-locking steel ball is pressed into the arc groove of the corresponding gear of shift fork axle,
Realize auto-lock function.
When scope gear cylinder is in high to low gear transfer process, as shown in Fig. 2 work of the cylinder piston 1 in left side air pressure
Under, moved from the left-most position of cylinder 2 to centre position, and then drive cylinder shift fork axle 15, scope gear shift fork 14 and shift fork
Universal driving shaft 13 moves right；
The serrate slot slope driving of shift fork universal driving shaft 13 slides pin 4 and moved up, until slide pin 4 head be ejected it is recessed
Groove is close to the external cylindrical surface of shift fork universal driving shaft 13；Slide pin 4 to move up, shift fork axle interlocking block 12 is extruded, shift fork axle interlocking block
12 promote its a series of interlocking plunger in right side and interlocking steel ball, until the groove of the gear shift fork axle 8 of the second interlocking steel ball 9 insertion 4/5
In.Now, main tank respectively keeps off interlocking steel ball or interlocking block is stuck in the groove of each gear shift fork axle, and is locked at because main tank is respectively kept off
Neutral gear position；I.e. in odd-side high to low gear transfer process, main tank can not put into gear.
When scope gear cylinder is in high gear position, as shown in figure 3, piston 1 is in the presence of the air pressure of left side, from interposition
Put and continue to move right, and then drive cylinder shift fork axle 15, scope gear shift fork 14 and shift fork universal driving shaft 13 to move right.Slide post
The head of pin 4 is fallen into the groove on the left side of shift fork universal driving shaft 13 from the external cylindrical surface of shift fork universal driving shaft 13.Pin 4 is slided to move down, its
The groove of external cylindrical surface again with shift fork axle interlocking block 12, interlocking steel ball and interlocking plunger center alignment.The now any gear of main tank
It can put into gear, it is illustrated that so that 4/5 gear shift fork axle 8 is put into gear as an example, 4/5 gear shift fork axle 8 moves, the second interlocking steel ball 9 from its of axle side
Side channel is extruded, and the second interlocking steel ball 9 promotes its a series of interlocking plunger in left side, the first interlocking steel ball 7 and shift fork axle interlocking block
12, until the insertion of leftmost shift fork axle interlocking block 12 is slided in the groove of pin 4；I.e. odd-side is in high gear position, and main tank can
Put into gear.
