It is preferably provided synchronizer, to guarantee that shift is steady in time.
A kind of gear transmission structure of more gear gearboxes provided by the utility model compared with the existing technology, have with
Lower advantage: it first, since the gear transmission structure of the gearbox includes power input shaft, power output shaft and is inputted with power
Axis, power output shaft multiple gear axis arranged in parallel, the transmission gear of power input shaft and the speed change of gear axis
Between by the connection of power shift gear that can be axially displaced, the transmission gear of gear axis is defeated by linkage gear and power
The transmission transmission gear of shaft connects, and the linkage gear intermeshing on adjacent gear axis has compact-sized, axis tooth cloth
The feature that office is reasonable and transmission efficiency is high；Second, fixing several according to radius length sequence due to being set on gear axis
The transmission gear of arrangement, the transmission gear on adjacent gear axis put in order the irregular distribution of identical and radius length, speed change
Increasing for gear can expand slewing range significantly, and the speed difference between adjacent gear further decreases, automobile gear shift mistake
Velocity variations are more smooth in journey.
Detailed description of the invention
Fig. 1 is the gear transmission structure schematic diagram of the more gear gearboxes of the utility model.
Specific embodiment
Gear transmission structure to a kind of more gear gearboxes provided by the utility model and work with reference to the accompanying drawing
Principle is described in further detail.
It is the gear transmission structure schematic diagram of more gear gearboxes provided by the utility model referring to Fig. 1.It is new to constitute this
The gear transmission structure of the more gear gearboxes of type includes power input shaft 1, power output shaft 2 and with state power input shaft 1, dynamic
The multiple gear axis 3 arranged in parallel of power output shaft 2, wherein suit fixes several according to half path length on gear axis 3
Spend tactic transmission gear 31, the identical and radius length that puts in order of the transmission gear 31 on adjacent gear axis 3 is joined
Difference cloth, passing through between the transmission gear 11 of power input shaft 1 and the transmission gear 31 of gear axis 3 can be axially displaced
Power shift gear connection, the transmission gear 31 of gear axis 3 passes through the transmission gear 21 of linkage gear 32 and power output shaft 2
Connection.
Its working principle is that: power enters in gearbox through power input shaft 1, the transmission gear 11 on power input shaft 1
It is connect with the transmission gear 31 on gear axis 3 by power shift gear, since the transmission gear 31 on gear axis 3 is more
It is a and arranged according to radius size sequence, it therefore can have the wider array of transmission ratio of range, widen speed change space further；Into
One step, with power input shaft 13 quantity of gear axis arranged in parallel be also multiple and transmission gear 31 put in order it is identical
And the irregular distribution of radius length, therefore speed change gear is considerably increased, the speed difference between adjacent gear is reduced, guarantees speed change
Process is smooth, improves the comfort of traveling.
In the present embodiment, the quantity of gear axis 3 is two, and the quantity of the transmission gear 31 on gear axis is equal
It is 6, i.e., realizes that gearbox has 12 speed change gears simultaneously by the axial movement of power shift gear.
In the gear transmission structure for constituting above-mentioned more gear gearboxes,
--- as preferable embodiment, 11 quantity of transmission gear of above-mentioned power input shaft 1 is multiple and according to half
Electrical path length sequence arranges, and the transmission gear 11 on power input shaft 1 is Chong Die with 31 position of transmission gear on gear axis 3, changes
Gear gear is at least engaged with the transmission gear 31 of the transmission gear 11 of one group of power input shaft 1 and gear axis 3 simultaneously, power
11 quantity of transmission gear on input shaft 1 increases, and further increasing power input shaft 1 and gear axis 3 has more pass
Dynamic ratio guarantees that speed-change process is more careful；
--- preferably, the quantity of above-mentioned power shift gear is multiple, wherein being located at a shift of 1 side of power input shaft
Gear is instant power shift gear, other power shift gears positioned at 1 other side of power input shaft are preparation power shift gear and are distributed in
The two sides of instant power shift gear, in the present embodiment, the quantity of power shift gear is 3, and one positioned at 1 upside of power input shaft changes
Keeping off gear is instant power shift gear 41, the as preparation power shift gear of 2 power shift gears on the downside of power input shaft 1 (42,
42 ') and it is located at the left and right sides of instant power shift gear 41, instant power shift gear 41 is real-time speed working gear, when wanting
When carrying out gear change operation, after electric-control system is by upshift or downshift signal, the control preparation nearest with target gear distance is shifted gears
Gear (42 or 42 ') work, i.e., nibble with the transmission gear 11 of power input shaft 1 and the transmission gear 31 of gear axis 3 simultaneously
It closes；
--- reverse gear 51 is set at least one gear axis 3, in the present embodiment, the radius of reverse gear 51 is big
In the radius of any one transmission gear 31 on gear axis 3, i.e. reverse gear 51 controls it by selector fork and passes in speed change
Do axial displacement on moving axis 3, realize and engage and separate with the constant speed gear 12 on power input shaft 1, power shift gear 41 with reverse gear
After gear 51 engages, whole transmission gears 31 of gear axis 3 are detached from working condition, and power output shaft 2 exports opposite move
Power.
