A gear shift shifting block 1 is filled, the gear shift shifting block 1 includes moving tooth 1-1, stir head 1-2, and the moving tooth 1-1, stir head 1-2, which are located at, to be changed
On the same diameter line of shelves axis 2.The stir head 1-2 and five reverse speed fork tails 6, three fourth gear shift fork tails, 7,1 grades of shift fork tails 8
Prong it is corresponding, the prong for sliding into respective notch shift fork tail for the axial movement by selector shaft 2 carries out gear shift, and described five fall
The prong 6-1 of shelves shift fork tail 6 to pre- hanger 9 distance, it is axial convex to pre-hung along selector shaft 2 with the stir head 1-2 of gear shift shifting block 1
The distance of wheel 5 is identical.
When hanging reverse gear, selector shaft 2 is moved axially, the stir head 1-2 of gear shift shifting block 1 is made to be moved to five reverse speed fork tails 6
In prong 6-1, because five reverse speed fork tails 6 prong 6-1 to the distance of pre- hanger 9 and the stir head 1-2 of gear shift shifting block 1 along axial direction
Distance to pre-hung cam 5 is identical, so pre-hung cam 5 at this time is located just at the lower section of pre- hanger 9.Pass through gear shift again later
The moving tooth 1-1 of shifting block 1 rotates selector shaft 2, and the stir head 1-2 of gear shift shifting block 1 is made to stir five reverse speed fork tails 6, five reverse speed forks
Axis 11 will drive five reverse speed forks first axial movement, the extension reverse gear being achieved in.Meanwhile five are stirred in stir head 1-2
When reverse speed fork tail 6, selector shaft 2 also will drive pre-hung cam 5 and rotate together, when pre-hung cam 5 contacts toggle arm 9,
Pre-hung cam 5 can rotate a low-angle compression retracteding position spring relative to fixed seat 3, until rotating to camshaft 15 by spacer pin 4
Limitation after i.e. stop.At this moment pre-hung cam 5 will start to stir pre- hanger 9, and one or two grades of shift fork axles 12 is made to drive one or two grades to dial
Plug 13 moves together, realizes two grades of pre-hungs, slows down to the spur gear of input shaft.Spur gear after deceleration can be with reverse gear
Spur gear smoothly engages, and avoids impact and the appearance of noise, solves the problems, such as that reverse gear beats tooth, while also improving driver
The comfort level of driving, increases the market competitiveness.After completing two grades of pre-hungs, pre-hung is crossed on the vertex of 5 free end of pre-hung cam
The end of arm 9 is detached from pre- hanger 9, at this moment pre-hung cam 5 can by return spring 14 elasticity restore realize return, and
Selector shaft 2 can move axially when reverse gear is made the return trip empty grade, and be staggered pre-hung cam 5 and pre- hanger 9, realize reverse gear and make the return trip empty shelves.The gear shift
Mechanism when replacing other gears in addition to reverse gear, pre-hung cam 5 in structure will not with it is pre- on one or two grades of shift fork tails 8
Hanger 9 contacts, which can guarantee the smooth gear shift between each gear.Moreover, the mechanism also simple and stable, without using
The parts such as reverse gear ring gear, reverse speed fork can realize the smooth extension shelves of reverse gear, reduce costs, simplify the assembly of speed changer,
Improve production efficiency.
