Gear assembly 6-2B comprises gear body 6-2B1 as shown in Figure 6, be provided with in the gear body 6-2B1 for the circular groove 6-2B2 that forward one-way clutch assembly 6-2C and reverse one-way clutch assembly 6-2A are installed, be provided with back-up ring 6-2C8 in the outside of circular groove 6-2B2.
Outer ring liner 6-2C4 bosom position is provided with for the spring fitting groove 6-2C41 that ring-spring 6-2C3 is installed as shown in Figure 7, spring fitting groove 6-2C41 both sides are provided with for the sloping shape roller slot 6-2C42 (as shown in Figure 4 and Figure 5) that places roller 6-2C2, and it is identical to be positioned at the direction of sloping shape roller slot 6-2C42 of both sides.
By 1 engagement of the clutch 6-2 on the jack shaft and driving shaft or separate, by the motion of jack shaft the first flower tooth 6-4 and jack shaft the second flower tooth 6-6, the engagement of meshing or unclamping jack shaft the first gear 6-3, jack shaft the second gear 6-5 or jack shaft the 3rd gear 6-7; The part effect of installing on two intermediate shaft structures 6 and this axle is identical, and just gear is not of uniform size causes, and gear is different.The moment of torsion of one of them intermediate shaft structure 6 passes to driven shaft 5 by reverse gear structure 4, realizes reverse gear; A mesomerism gear that increases is realized reverse gear; Wherein, driving shaft 1 and driven shaft 5 eccentric designs are to realize the velocity ratio differentiation of two jack shaft 6-1.
Oppositely one-way clutch assembly 6-2A is the same with the structure of forward one-way clutch assembly 6-2C, installs on the contrary, and unique difference is different with the inner circle spline diameter of reverse flower keyboard at forward flower keyboard 6-2C7.
The inside end of inner ring 6-2C1 touch the circular groove 6-2B2 in the middle of the gear body 6-2B1, and the back-up ring 6-2C8 that an outside end is installed on the gear body 6-2B1 blocks, and can rotate; On the inner ring 6-2C1 spline tooth is arranged, can mesh with forward flower keyboard 6-2C7; Its inner plane contacts with the interior edge face of pusher dog 6-2C5.
Outer ring liner 6-2C4 is fixed by center side wall and the gland of gear body 6-2B1 by the spline tooth on it and gear body 6-2B1 engagement, and the centre has spring fitting groove 6-2C41, places ring-spring 6-2C3; Have a lot of sloping shape roller slot 6-2C42 on the liner 6-2C4 of outer ring, roller 6-2C2 realizes surmounting when the large end position of notch, realizes locking when small end; Roller 6-2C2 promotes by pusher dog 6-2C5, and the ring-spring 6-2C3 between roller 6-2C2 and the pusher dog 6-2C5 can remedy precision deficiency or wearing and tearing.
Stage clip 6-2C6 stretches out a plurality of spring pin 6-2C61, in the situation that do not have stressedly, spring pin 6-2C61 catches on pusher dog 6-2C5, forces the large end of pusher dog 6-2C5 and the roller 6-2C2 notch on the liner 6-2C4 of outer ring to move, and realizes surmounting; When being subject to the pressure of forward flower keyboard 6-2C7, spring pin 6-2C61 compression is extended in the axis projection direction, and the small end that promotes pusher dog 6-2C5 and the roller 6-2C2 notch on the liner 6-2C4 of outer ring moves, and realizes locking.
When gearbox adopted two intermediate shaft structures, the below narrated referred to as jack shaft one and jack shaft two for convenient:
If the moment of torsion transfer route is: the first gear of driving shaft 1 → clutch 6-2 → jack shaft one → jack shaft one, the gearbox state is that forward flower keyboard 6-2C7 and the reverse flower keyboard on the clutch 6-2 all is locking state, forward flower keyboard 6-2C7 on jack shaft two clutches and reverse flower keyboard all are releasing orientations, the second flower tooth of the first flower tooth of jack shaft two, the second flower tooth of jack shaft two and jack shaft one is releasing orientation, and the first flower tooth of jack shaft one and the first gear of jack shaft one mesh.
Arrive the first gear of jack shaft two if need to shift up, step is:
The first spline of jack shaft two and the engagement of the first gear of jack shaft two, the reverse flower keyboard on the clutch of jack shaft one unclamps; Forward flower keyboard 6-2C7 on the clutch of jack shaft two and reverse flower keyboard are locked; Because be to shift up, the forward flower keyboard 6-2C7 on the clutch of jack shaft one is surmounted; Do not have moment of torsion out of stock, realize gearshift in zero second; Forward flower keyboard 6-2C7 on the clutch of jack shaft one unclamps, and the first flower tooth of jack shaft one and the first gear of jack shaft one unclamp.In this process, after forward flower keyboard 6-2C7 and reverse flower keyboard unclamped, the part of axle no longer was subject to moment of torsion in the clutch 6-2 of jack shaft one and jack shaft two, realizes release under the effect of stage clip 6-2C6.
If need downshift to arrive the second gear of jack shaft two, step is:
The second gear (13) engagement of the first spline of jack shaft two and jack shaft two, the forward flower keyboard 6-2C7 on jack shaft one clutch unclamps; Forward flower keyboard 6-2C7 on the clutch of jack shaft two and reverse flower keyboard are locked; Owing to being downshift, the reverse flower keyboard on the clutch of jack shaft one is surmounted, and realizes gearshift; Reverse flower keyboard on the clutch of jack shaft one unclamps, and the first flower tooth of jack shaft one and the first gear of jack shaft one unclamp.
Reverse gear: moment of torsion is delivered on the 3rd gear of jack shaft two, realizes by reverse gear structure (20).
Parking shelves: all flower keyboard total deadlocks on the clutch of the clutch of jack shaft one and jack shaft two.
It is emphasized that, it more than is preferred embodiment of the present invention, be not that body is done any type of restriction in appearance, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
