As shown in Figure 1, the hybrid gearbox is mainly by clutch housing, case of transmission, an axle assembly, jackshaft
Assembly, two axle assemblies and automatic gearshift composition.Clutch housing and case of transmission are bolted to form an envelope
The cavity closed, an axle assembly, countershaft assembly, two axle assemblies are installed in the cavity by bearing support, and motor is connected to shell
Below, by connection inside hollow shaft and speed changer, AMT moves mechanism loaded on above case of transmission automatically.Engine is in the past
One axis input power of face, motor is from the rear through hollow shaft input power, it can be achieved that engine driving/motor independently drives, is mixed
It closes driving, stop/drive a vehicle the functions such as power generation and Brake energy recovery.Electropneumatic self shifter machine is arranged in the hybrid gearbox
Structure, it can be achieved that speed changer internal synthesizer and sliding sleeve mutually indepedent extension shelves.The gearshift structure is simple, easy to control, surely
It is fixed reliable.
One axle assembly includes an axis 3 and a shaft gear 4, and an axis 3 is connect by spline with a shaft gear 3 and is fitted together.
Countershaft assembly includes jackshaft 20, intermediate shaft transmission gear 15, one shelves gear 17 of jackshaft and intermediate spindle motor
Transmission gear 19, three on jackshaft, become countershaft assembly, such countershaft assembly has two by interference fit
Root, be placed in two axle assembly two sides.
Two axle assemblies include synchronizer 7, two axis, one shelves gear 16, in conjunction with gear ring 9, hollow shaft 11, sliding sleeve 10, hollow shaft tooth
Wheel 18 and two axis 14, synchronizer 7 and combination gear ring 9 are connect by spline with two axis 14, two axis, one shelves gear 16 and hollow shaft 11
Empty set is on two axis 14, and for 18 empty set of cannon pinion in hollow shaft 11, sliding sleeve 10, can on the external splines of hollow shaft front end
It moves left and right, the above part dress is integrated composition main shaft assembly.One axle assembly, countershaft assembly and main shaft assembly pass through bearing branch
It supports in the cavity that clutches shell 5 and case of transmission 6 form.
Motor 12 is connected to 6 rear end of case of transmission, and 12 internal spline of motor is connected with 11 external splines of hollow shaft, and two axis pass through
Hollow shaft reaches motor rear end, and rear end is equipped with rear bearing cover 13 and output flange 21, for supporting two axis and output power.
In above-mentioned assembly, a shaft gear and intermediate shaft transmission gear engagement, one shelves gear of one shelves gear of jackshaft and two axis
Engagement, cannon pinion and motor-driven gear engagement, AMT automatic gearshift 8 can stir synchronizer 7 and sliding sleeve 10 or so
Mobile realize hangs shelves.
All aluminium alloy structure, small in volume can be used in the shell of hybrid gearbox of the present invention, and speed changer uses
Low-powered engine (increases motor driven, so corresponding engine can reduce), can reduce oil consumption and discharge；Using motor
Starting, starting torque is big, and starting performance improves, and discharge value is greatly lowered.
There are several types of operating modes for the hybrid gearbox:
Electric-only mode: when vehicle is worked with electric-only mode, clutch 2 is separated, and motor independently drives, and vehicle can be one
To three gear gear downward drivings.As shown in Figure 1, AMT automatic gearshift 8 pushes sliding sleeve 10 to move right and 18 knot of cannon pinion
It closes, while pushing synchronizer 7 to move right and combining (gear all has in conjunction with gear ring) with two axis, one shelves gear 16, complete motor 1
Shelves driving, power transmits at this time are as follows: (hollow shaft front end is external splines to 12 → hollow shaft of motor, 11 → sliding sleeve 10, and sliding sleeve passes through flower
Key connection covers in hollow shaft) → 20 → jackshaft of cannon pinion 18 → motor-driven gear, 19 → jackshaft, one shelves gear 17
One 16 → synchronizer of shelves gear of → bis- axis, 7 → bis- 14 → output flange of axis 21.
It is pure electric 2 grades, power transmission line is when synchronizer 7, which is moved to the left, to be combined with a shaft gear 4: motor 12 →
19 → jackshaft of hollow shaft 11 → sliding sleeve, 10 → cannon pinion, 18 → motor-driven gear 20 → centre shaft transmission gear 15 →
One 4 → synchronizer of shaft gear, 7 → bis- 14 → output flange of axis 21.
AMT behaviour's automatic gearshift 8 pushes sliding sleeve 10 to be moved to the left and combine gear ring 9 to combine, while synchronizer 7 being pushed to return
To intermediate neutral gear position, 3 grades of motor drivings, power transmitting are completed are as follows: 12 → hollow shaft of motor, 11 → sliding sleeve 10 → combine gear ring 9
→ bis- 14 → output flanges of axis 21, also referred to as motor direct high.
Pure engine mode: when vehicle is operated alone by engine, there are two gears.AMT automatic gearshift 8 pushes together
Step device 7 moves right to be combined with two axis, one shelves gear 16, realizes 1 grade of driving, power transmission route are as follows: 1 → clutch of engine 2
3 → mono- 4 → centre of shaft gear, 15 → jackshaft of shaft transmission gear, 20 → jackshaft, one shelves gear, 17 → bis- axis, one grade of tooth of → mono- axis
Take turns 16 → synchronizer, 7 → bis- 14 → output flange of axis 21；When synchronizer 7, which is moved to the left, to be combined with a shaft gear 4, exactly send out
2 grades of motivation, power transmission line is: 1 → clutch of engine, 2 → mono- axis, 3 → mono- 4 → synchronizer of shaft gear, 7 → bis- axis 14 →
Output flange 21, alternatively referred to as direct high.
Hybrid mode: when vehicle works under hybrid mode, engine and driving motor are worked at the same time.Mixing
Power has following mixed mode: 1 grade of engine, 1 grade of & motor, 2 grades of engine, 2 grades of & motor, starts 1 grade of engine, 3 grades of & motor
When 2 grades of machine, 3 grades of & motor, that is, under above several gearing regimes, motor and engine provide driving force, speed changer simultaneously
Power is converged into output to ring flange 19, to realize power mixing output.
Brake power generating mode: practical is exactly to be generated electricity using vehicle movement inertia by transmission drive motors.Vehicle is being made
Under dynamic power generation mode, speed changer is driven by ring flange one end, motor operates power generation under the drive of speed changer, it charges to battery,
Inertia energy is consumed, abrupt deceleration vehicle effect is played, recycles braking energy.Motor can operate hair under 1,2,3 grade of motor of gear
Electricity recycles braking energy, and brake power generating is motor-driven inverse process.
Power generation mode: so-called power generation mode is exactly charged the battery using engine.This speed changer is in feelings of driving a vehicle and stop
It can generate electricity under condition.Vehicle is placed in intermediate neutral gear position under the power generation mode that stops, by synchronizer 7, sliding sleeve 10 be moved to the left with
Cannon pinion 18 combines, engine driven generators power generation.Power transmission line is: 1 → clutch of engine, 2 → mono- axis 3
→ mono- 4 → intermediate shaft transmission gear 15 → jackshaft, 20 → motor-driven gear, 19 → cannon pinion of shaft gear, 18 → sliding sleeve 10
11 → motor of → hollow shaft 12.Driving power generation can be realized in the case where mixing dynamic various operating conditions, but motor is not intended to provide at this time
Power, but battery capacity storage is converted by engine power.
The present invention be it is a kind of can self shifter three gear hybrid gearboxes, which has energy-saving and environmental protection, manipulation
Comfortable feature can satisfy the various working demand in commercial vehicle traveling, it can be achieved that the pure electricity starting of large torque, pure electric vehicle are driven
Dynamic, engine independently drives, motor, engine combined power driving, Brake energy recovery, the functions such as parking power generation.Pass through
Reasonable structure design and policy control, make engine be in efficiency operation area always, to achieve energy-saving and emission reduction purposes.
