Description
The present invention relates to a kind of hybrid gearboxes.
(input and output shaft are in same straight line usually using two grades of coaxial speed variators for hybrid electric vehicle in existing market
On), the problem of presence in use: vehicle is short of power, lacks two grades of coaxial speed variators of more large torque (1000Nm), economic vehicle
Velocity modulation is whole to be limited in scope (second gear speed ratio is 1, immutable), and speed changer installation length is long, because vehicle rear overhang limited length makes to become
Fast device matching vehicle is limited.Therefore, how to make speed changer wider raising economic speed in hybrid power assembly, improve whole
Vehicle fuel economy improves vehicle dynamic property, meets more multi-vehicle-type and matches needs, is the speed changer in hybrid power system
Developing direction and the speed changer develop purpose to be achieved.
Technical problem solved by the present invention is the present invention provides a kind of hybrid gearbox, biography can be easily adjusted
Dynamic ratio.
The technical scheme is that a kind of hybrid gearbox, including the input shaft that is located on same axis and defeated
Shaft, the input shaft are equipped with input shaft shaft gear,
A shelves gear and intermediate gear, a shelves gear and described two are equipped with by bearing respectively on the output shaft
Synchronizer is equipped between shelves gear, which is mounted on the output shaft by the way that spline is axially slidable；
Further include the jackshaft for being parallel to input shaft, output shaft, is successively fixedly installed jackshaft axis on the jackshaft
Gear, the first countershaft-gear and the second countershaft-gear, the jackshaft shaft gear are often engaged with the input shaft shaft gear,
First countershaft-gear is often engaged with the intermediate gear, and second countershaft-gear is often nibbled with a shelves gear
It closes, the synchronizer is matched with first countershaft-gear (9), second countershaft-gear respectively.
The speed ratio of one shelves gear is 2.8, and the speed ratio of the intermediate gear is 1.2.
The output shaft is equipped with the external splines for connecting motor.
The input shaft is integrally formed with the input shaft shaft gear, and the jackshaft is with the jackshaft shaft gear
It is integrally formed.
The beneficial effects of the present invention are: input shaft power drives jackshaft shaft gear, jackshaft by input shaft shaft gear
Shaft gear drives jackshaft rotation, and jackshaft drives the first countershaft-gear and the second countershaft-gear, the first jackshaft simultaneously
Gear drives intermediate gear rotation, and the second countershaft-gear drives shelves gear rotation.When needing to shift to first gear, on output shaft
Synchronizer and a shelves gear between transmit power, synchronizer is separated with intermediate gear, at this time a shelves gear pass through synchronizer band
Dynamic output shaft rotation, and intermediate gear dallies on output shaft；When needing to change to two grades, the synchronizer on output shaft and two grades
When transmitting power between gear, synchronizer is separated with a shelves gear, and intermediate gear drives output shaft rotation by synchronizer at this time,
And a shelves gear dallies on output shaft.The configuration of the present invention is simple is capable of increasing the adjusting range of transmission ratio, improves vehicle economy
Vehicle speed range plays the effect of further fuel-economizing to improve vehicle fuel economy in hybrid power system.
Fig. 1 is the structural diagram of the present invention.
Present invention will be further explained below with reference to the attached drawings and examples:
Referring to Fig. 1, a kind of hybrid gearbox is described including the input shaft 1 and output shaft 2 being located on same axis
It is fixedly installed with input shaft shaft gear 3 on input shaft 1, a shelves gear 4 and two is equipped with by bearing respectively on the output shaft 2
Shelves gear 5, is equipped with synchronizer 6 between a shelves gear 4 and the intermediate gear 5, which can axially be slided by spline
Dynamic is mounted on the output shaft 2；Further include the jackshaft 7 for being parallel to input shaft 1, output shaft 2, on the jackshaft 7 according to
It is secondary to be fixedly installed jackshaft shaft gear 8, the first countershaft-gear 9 and the second countershaft-gear 10, the jackshaft shaft gear 8
It is often engaged with the input shaft shaft gear 3, first countershaft-gear 9 is often engaged with the intermediate gear 5, in described second
Between shaft gear 10 often engaged with a shelves gear 4, the synchronizer 6 respectively with first countershaft-gear 9, described second
Countershaft-gear 10 matches.The speed ratio of one shelves gear is 2.8, and the speed ratio of the intermediate gear is 1.2.Input shaft with it is defeated
Enter axis shaft gear to be integrally formed, jackshaft is integrally formed with jackshaft shaft gear.The output shaft 2 is equipped with for connecting electricity
The external splines of machine, motor shaft are the type of attachment of internal spline, and output shaft on the one hand can be made to transmit enough torques, on the other hand may be used
It is effective to shorten speed changer integral installation length, make speed changer on vehicle convenient for arrangement.The working principle of the invention is in this way
: 1 power of input shaft drives jackshaft shaft gear 8 by input shaft shaft gear 3, and jackshaft shaft gear 8 drives 7 turns of jackshaft
Dynamic, jackshaft 7 drives the first countershaft-gear 9 and the second countershaft-gear 10 simultaneously, and the first countershaft-gear 9 drives two grades of teeth
5 rotation of wheel, the second countershaft-gear 10 drive a shelves gear 4 rotation.Synchronizer 6 when needing to shift to first gear, on output shaft
Power is transmitted between a shelves gear 4, synchronizer 6 is separated with intermediate gear 5, and a shelves gear 4 is driven defeated by synchronizer 6 at this time
Shaft 2 rotates, and intermediate gear 5 dallies on output shaft 2；When needing to change to two grades, the synchronizer 6 on output shaft and two grades
When transmitting power between gear 5, synchronizer 6 is separated with a shelves gear 4, and intermediate gear 5 drives output shaft by synchronizer 6 at this time
2 rotations, and a shelves gear 4 dallies on output shaft 2.
