Abstract

The invention belongs to the technical field of key automobile components. In the shifting process of an existing automatic mechanical transmission (AMT) or manual transmission, power of an engine 1 cannot be transmitted to an output shaft 11, and accordingly the problem of power failure exists; riding comfort of an automobile is affected by the problem, and further an applicable scope of transmissions of the kind is affected. Through a method that a motor 4 is mounted at one end, opposite to a differential 12, of the output shaft 11, a function that the motor 4 substitutes for the engine to output power in the shifting process is realized, and accordingly the problem of power failure is solved. Meanwhile, the motor can assist the automobile to have hybrid functions in motor-assisted starting, boosted accelerating, braking energy recovery and the like.

Description

A kind of mixed motivity type automation change speed gear box or Manual transmission

Technical field

The technical field of the invention is the vehicle key parts.

Background technology

As everyone knows, existing vehicle manual change speed gear box must make master clutch between driving engine and change speed gear box separate shifting gears, and the gearshift sleeve of change speed gear box inside also must experience the process that has a separation and mesh, therefore in this process, the power of driving engine can't pass to vehicle, also has the power interruption problem.This problems affect has arrived the travelling comfort of vehicle, but and then has affected the field of application of this type of change speed gear box.The automation change speed gear box developed on the hand gear box foundation (being AMT) is because its basic structure is identical with Manual transmission, thereby can't overcome the problems referred to above.

In addition, existing automation change speed gear box and Manual transmission do not possess hybrid power functions such as electronic start assisting, power-assisted acceleration, braking energy recovery.

Summary of the invention

The present invention, by the method for an end (end contrary with the diff 12) mounted motor 4 at output shaft 11, has realized replacing the function of engine output power by motor 4 in above-mentioned shift process, thereby has overcome the problem of above-mentioned power interruption.Detailed process is: when master clutch 2 separates for gearshift, motor 4 starts immediately and again before closure, is continuing to keep the power output to output shaft 11 at gearshift end, master clutch 2.At master clutch 2, again after closure, the needs of visible driving, continue to keep or the output of middle stopping power.

Simultaneously, motor 4 can also be realized following hybrid power function:

One,, during vehicle start, driving engine 1 can be in flameout state.Now, master clutch 2 separates, and motor 4 can work independently, and makes vehicle complete starting.After vehicle obtains certain speed, restart driving engine 1, closed master clutch 2, driving engine 1 provides power for vehicle.Make thus driving engine avoid as much as possible the slow speed of revolution work area, thereby emission behavior and fuel economy are improved;

Two, motor 4 can have the function of electrical generator concurrently.As long as vehicle place on the go, particularly, in the braking procedure of vehicle, motor 4 can be generated electricity under the driving of output shaft 11, and by the electrical power storage sent in storage battery.Can make thus originally the braking energy of loss in vain be recycled utilization.This function also can realize with driving engine, it being charged when the storage battery dump energy is on the low side;

Three, in the vehicle traveling process, motor 4 can in the situation that in storage battery remaining electric power allow outputting power at any time, or drive separately vehicle, or work together with driving engine 1 so that vehicle obtains better acceleration capability.

The accompanying drawing explanation

1, driving engine; 2, master clutch; 3, input shaft; 4, motor; 5, tween drive shaft; 6, gear mesh (showing 6 pairs in figure, is typical 5 grades of change speed gear boxs configuration); 7, selector fork; 8, gearshift sleeve (in figure, showing 3); 9, gear box; 10, gearbox shifting fork controls mechanism; (for Manual transmission, this device is replaced by hand-gear shift lever); 11, output shaft; 12, diff

That accompanying drawing shows is the embodiment of the present invention automation change speed gear box (being AMT).

The common working process of automation change speed gear box is: driving engine 1 by master clutch 2 and input shaft 3 by transmission of power to tween drive shaft 5.Tween drive shaft 5 further passes to gear mesh 6 by gear mesh 6 (its number depends on the gear number of Gearbox design) by power and is positioned at the gear on output shaft.Now, depend on the engagement situation of gearshift sleeve 8 (its number depends on the gear number of Gearbox design) and gear mesh, power will be passed to output shaft 11 by that gearshift sleeve in engagement, and finally by diff 12, be passed to wheel.

The output shaft of motor 4 can directly be connected with the output shaft of change speed gear box 11, also can pass through gear, chain or other any mechanisms and indirectly be connected.The housing of motor 4 can be fixed on gear box 9.

When needs are shifted gears, at first, master clutch 2 separates; Now motor 4 can start to guarantee that the power of vehicle can not interrupt; Then, selector fork 7 (for the situation of Manual transmission, is the gear level of being handled by navigating mate at selector fork control mechanism 10.In accompanying drawing, do not mean.Lower with) control under, make gearshift sleeve in engagement from institute's gears in mesh to disengaging; Then, selector fork 7 is under the control of selector fork control mechanism 10, and the gearshift sleeve that will be determined by the target gear is pushed the target gear mesh to and made it engagement; Finally, master clutch 2 closures, shift process completes.

The specific embodiment

Slightly.
