Abstract

The utility model relates to a power transmission system of a hybrid powered car, in particular to a hybrid powered car gearbox, the utility model is improved on the basis of car gearbox techniques, power of an engine and a motor is introduced to the power transmission system, and the power is effectively distributed, controlled and adjusted by the power transmission system to achieve the purpose of utilizing a small horsepower motor for energy saving and environment protection to pull a large car. The hybrid powered car gearbox outputs power through a gearbox gear group (7). The hybrid powered car gearbox is characterized in that a first clutch is engaged and connected with gears of a gear group (1) and the gearbox gear group (7) to output the power transmission of the engine; and a motor clutch group (14) is directly connected with a layshaft (9) to output the power transmission of the motor.

Description

The hybrid vehicle change speed gear box

Technical field

The utility model relates to a kind of on hybrid vehicle, the system that driving engine and motor power are control effectively, i.e. hybrid vehicle change speed gear box.

Background technology

Hybrid vehicle is the product of the fuel automobile in current energy scarcity period to the electronlmobil transition, hybrid vehicle is exactly that the power of motor is introduced automobile, directly introduce motor and need high-power, not so starting difficulty, add motor again and also will increase controller, battery, a series of problems such as layout.

The utility model content

In order to address the above problem, the utility model adopts this solution of hybrid vehicle change speed gear box, it is characterized in that comprising:

On the basis of automobile variable speed box technology, the change speed gear box input shaft is changed over first clutch and gear cluster, the power of driving engine is exported through output shaft by the gear mesh of first clutch axle and gear cluster and gearbox gear group.

Countershaft is the major part of transferring power, and the power of motor is directly to be connected with countershaft by the electric motor clutch group, also can be by the gear mesh of electric motor clutch gear cluster and gearbox gear group, through countershaft. output shaft output.

First clutch and electric motor clutch can be controlled various function conversions, reload buffer power-transfer clutch on first clutch and electric motor clutch, the impact that brings in the time of can reducing work.

If load onto oil pump on countershaft, can also solving to stall, back each needs the oily problem of using of hydraulic oil department.

The specific embodiment

Referring to accompanying drawing 1, accompanying drawing 4, the hybrid vehicle change speed gear box, be to output power by gearbox gear group 7, it is characterized in that: engine power transmits by first clutch and gear cluster 1, outputs power with gearbox gear group 7 gears mesh, the motor power transfer mode have two kinds, its first kind by electric motor clutch group 14, with gearbox gear group 7 in countershaft 9 direct connections, second kind of connection mode is by electric motor clutch and gear cluster 20, be connected with countershaft 9 gears mesh.

Referring to accompanying drawing 1, accompanying drawing 4, when engine operation, power transmits by first clutch and gear cluster 1, it is made up of the slotting tooth 2 of power-transfer clutch, input shaft 3, first clutch 5, energy disperser 6, first clutch axle and gear 4, with the gear mesh of gearbox gear group 7, by countershaft 9, output shaft 8 outputs.

Referring to accompanying drawing 1, accompanying drawing 4, its power driven mode one during machine operation: motor power transmits by electric motor clutch group 14, it is by motor coupler 13, motor shaft 12, electric motor clutch 11, energy disperser 16 is formed, by motor coupler 13, directly be connected with countershaft 9: referring to accompanying drawing 2. motor power type of drive two: motor power transmits by electric motor clutch and gear cluster 20, it is by motor coupler 13, motor shaft 12, electric motor clutch 11, energy disperser 16, motor gear axle 17, motor gear 18 is formed, referring to accompanying drawing 3, the gear of motor gear 18, gear mesh with countershaft 9, output power by gearbox gear group 7.

No matter be engine power or motor power, enter among gearbox gear group 7, the countershaft 9 after, regulate the speed with the conversion gear, adjust moment of torsion with the throttle size, can use the fraction horsepower motor like this, export big moment of torsion.

Can also be when the needs high-power with first clutch 5 and electric motor clutch 11 adhesives simultaneously, at this moment driving engine and motor can be worked simultaneously, to reach torque peak output.

When gently touching on the brake, automobile inertial power by output shaft insert tooth 10, output shaft 8, gearbox gear group 7, through countershaft 9 drive motor passive transports, generating also reaches the purpose of energy-conservation deceleration simultaneously to battery charge.

When engine operation, as electric motor clutch 11 adhesives, power is by countershaft 9 and gearbox gear group 7, and the drive motor passive transport generates electricity to battery charge.

Referring among accompanying drawing 3, the energy disperser 16 recoil spring being housed, slotting tooth is installed on the motor shaft 12, and terminal pad is installed on the power-transfer clutch, the impact to reduce when power-transfer clutch is worked, the traveling comfort (energy disperser 6 also is like this) when increasing operation.

Oil pump 21 is the fuel-feeds system for auto body and change speed gear box service itself, with the energy problem behind the solution motorcar electric.
