Technical field
This utility model is related to new energy vehicle field, and in particular to a kind of hybrid power system variator.
Background technology
Country new energy vehicle market is burning hot at present, and plug-in hybrid electric vehicle type efficiently solves the continuation of the journey of pure electric vehicle type The not enough problem of mileage, and conventional power system is combined together with pure power-driven power system, respective inferior position is compensate for, Again the advantage of both sides is maximized.Current less than 10 meters plug-ins mixing mini-bus manufacturing technology is at home or blank, so it is our Case needs to develop a kind of little centre-to-centre spacing (centre-to-centre spacing is 116mm), 5 forward gears, axial dimensions, and short (housing forward end face is to flange Side surface is 421mm), moment of torsion 800Nm, ratio coverage are big, and two gear speed are than the double intermediate gearboxs up to more than 3;To coordinate mixing Dynamical system is used, and variator front end is reserved and motor connection interface, is reserved and management system connecting interface, bottom on upper lid With intermediate shaft brake, the demand of new forms of energy City bus market is met.This programme is intended to give full play to double intermediate gearbox chis It is very little little, lightweight, the advantage of large carrying capacity, it is few to meet buses gear requirement again, large carrying capacity, and fast grade of starting needs Ask.
Utility model content
The purpose of this utility model is for above-mentioned the problems of the prior art, there is provided a kind of hybrid power system becomes Fast device.
To achieve these goals, the technical solution adopted in the utility model is:Including the input shaft with input gear, Input gear is often engaged with the middle shaft transmission gear on jackshaft, and described jackshaft is provided with two and symmetrical position In the both sides of main shaft;The front end connection input shaft of main shaft, the coupling flange, output end disk of main shaft are provided with main shaft tooth on main shaft Wheel, is provided with sliding sleeve between mainshaft gear, the countershaft-gear of often engagement corresponding with mainshaft gear is provided with jackshaft;Described Selector fork axle is provided with above main shaft, be provided with selector fork axle for drive sliding sleeve move selector fork, sliding sleeve with Mainshaft gear can pass through spline connection;Intermediate shaft brake is provided with below described jackshaft.
Five mainshaft gears are installed on described main shaft, are reversed gear with five forward and one, one keeps off and reverses gear altogether Same gear, the ratio coverage 0.754~5.881 of the five forward, the speed reversed gear is used to compare for 5.429.
It is provided with described selector fork axle and the one of selector fork axle and back fork movement can be driven to reverse gear Shifting block moves block.
Described input shaft is connected on case of transmission;The front end of jackshaft is connected on case of transmission, and rear end connects It is connected on bonnet housing;By being connected in input shaft without outer ring cylinder roller bearing, rear end is connected to bonnet for the front end of main shaft On housing.
The reserved through hole with motor connection in described case of transmission front end, reserves on lid on case of transmission and manipulates control The interface of system connection processed.
Described input gear is obtained by being integrally formed processing with input shaft.
The axle center right side of jackshaft is located to direction of principal axis, the axle center of intermediate shaft brake input shaft is input into along variator ring flange Lower section.
The axle center of intermediate shaft brake input shaft is 20 ° with the angle of the axle center place vertical direction of jackshaft.
Compared with prior art, this utility model speed changer structure is compact, it is ensured that variator installation length can be realized 421mm (from case of transmission front end face to output flange rear end face), therefore it is beneficial to arrangement.Shifted gears using full sliding sleeve, changed Gear is light, coordinates the control system of hybrid power, controls speed discrepancy, enter to keep off probability big during gearshift.In being provided with below jackshaft Between shaft brake, the rotating speed of transmission countershaft and its associated part can be reduced rapidly during variator upshift, so as to contract Short lock in time, shift time and power interruption time are reduced, reduce power loss.Variator of the present utility model is without manipulation Device, each gear self-locking spring pressing plate are individually compressed, and upper cover controlled window prevents debris from entering box house using cover plate, real With reliability.
Further, this utility model intermediate shaft brake is located at jackshaft obliquely downward, from variator ring flange towards input Axle sees that the axle center of intermediate shaft brake input shaft is located at the lower right in lower-left jackshaft axle center, both line and jackshaft axles The angle of heart place vertical direction is 20 °, shortens the size on variator vertical direction, is more beneficial for the arrangement of car load.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
Referring to Fig. 1,5 gear automobile speed changer of this utility model, inside variator, include input shaft 1 (input shaft 1 and input tooth Wheel is integrated), main shaft 5 and five mainshaft gears 6, be provided with sliding sleeve 7 between mainshaft gear 6, the both sides of main shaft 5 have two it is completely right The jackshaft 3 of title, middle shaft transmission gear 2 are often engaged with the input gear of input shaft 1, remaining gear 4 on jackshaft 3 with it is right The mainshaft gear 6 answered often is engaged.Input shaft 1 is connected on case of transmission, and the front end of jackshaft 3 is connected to case of transmission On, rear end is connected on bonnet housing, and by being connected in input shaft 1 without outer ring cylinder roller bearing, rear end connects 5 front end of main shaft It is connected on bonnet housing, the coupling flange, output end disk of main shaft 5.
The course of work of the present utility model is:The power of electromotor is connected with the power of motor by clutch, is passed to The input shaft 1 of variator, the input gear on input shaft 1 are often engaged with middle shaft transmission gear 2, drive jackshaft 3 Rotated, countershaft-gear 4 is often engaged with mainshaft gear 6, mainshaft gear 6 dallies on main shaft 5.Sliding sleeve 7 is passed through with main shaft 5 Spline connection, and selector fork 8 is straddled on sliding sleeve 7, (one falls to control gear shifting pulling head moving gear shift shift fork 8 by steerable system Keeping off and guide block being moved for gear shifting pulling head, guide block drives shift fork axle 9 and a back fork 10 to move), selector fork 8 drives sliding sleeve 7 one Movement is played, when sliding sleeve 7 is combined with the internal spline of mainshaft gear 6, main shaft 5 is integrally formed with mainshaft gear 6, according to certain speed Power is transmitted than rotation, then power is exported through ring flange 11.
During upshift, intermediate shaft brake 12 participates in the process of work:
Variator from low gear hang high gear when, first step on clutch, the power input of open slew device, 7 times neutral gear positions of sliding sleeve.This When due to the inertia of vehicle, think to continue according to the rotating speed uniform rotation before keeping off of making the return trip empty in 11 a period of time of main shaft 5 and ring flange. 5 rotating speed of rotating ratio main shaft now of high gear mainshaft gear 6 is much higher, and intermediate shaft brake 12 participates in work and provides resistance, will The rotating speed of jackshaft 3, input shaft 1 and mainshaft gear 6 is reduced rapidly, and the very short time just can be by 6 rotating speed of high gear mainshaft gear It is reduced near the speed of mainshaft and completes synchronization, then sliding sleeve 7 hangs high gear, completes upshift process.The work of intermediate shaft brake 12 Time is that sliding sleeve 7 disengages low gear gear to a period of time hung into before high gear gear.
