Description
Technical field
The utility model belongs to automobile technical field, is related to a kind of hybrid power system of automobile.
Background technology
As the measure of countries in the world environmental protection is increasingly stringenter, hybrid vehicle is since its is energy saving, low emission etc.
Feature becomes a much-talked-about topic of automotive research and exploitation.Hybrid vehicle refers to equipping two kinds of power resources simultaneously, i.e.,
Automobile of the heat dynamic resource (being generated by traditional gasoline engine or diesel engine) with electrodynamic source (battery and motor).By mixed
It closes and uses motor on power vehicle so that dynamical system can require flexible modulation according to the actual operating mode of vehicle, and send out
Motivation is maintained in the best region of comprehensive performance and works, to reduce oil consumption and discharge.
As Chinese patent literature discloses a kind of hybrid power system (application number of automobile：200910140702.9), packet
Include engine, first motor, the second motor, clutch, transmission mechanism and battery with transmission shaft, the first motor and
Two motors are connected respectively to the battery, and the motor shaft of second motor is connect with the transmission mechanism, the engine
The motor shaft of the motor axis connection of output shaft and the first motor, the first motor is hollow shaft, the clutch setting
In the motor shaft of the first motor, the active part of the clutch and the inner wall of the motor shaft of the first motor connect
It connects, the secondary part of the clutch and the transmission axis connection.The system is coaxial by the second motor, engine and generator
Arrangement, such arrangement structure is more regular, and arrangement is very convenient.But in the system motor shaft of the second motor with
Transmission shaft is coaxially connected, and the power of the second motor and engine is to pass to wheel using transmission mechanism by transmission shaft
, that is to say, that the second motor and engine are carried out to vehicle by same power transmission route and with identical speed ratio
Power output, it is low for the torque demand of driving motor at this time if speed is relatively high, but engine speed is high when high speed, meeting
It causes oil consumption to increase noise simultaneously to increase.And if speed ratio is relatively low, although oil consumption can be reduced, driving motor just need have compared with
Big torque causes the size of vehicle-body width direction to increase, therefore be unfavorable for vehicle body to bring the increase of driving motor size
The optimization design of size.
Invention content
The purpose of this utility model is the presence of the above problem in view of the prior art, it is proposed that a kind of hybrid power of automobile
System, technical problem to be solved in the utility model are：Under the premise of ensureing fuel economy, the ruler of vehicle body can be reduced
It is very little.
The purpose of this utility model can be realized by following technical proposal：A kind of hybrid power system of automobile, including
Driving motor, power output shaft, jackshaft and the engine that power output shaft can be driven to rotate, the power output shaft and centre
Axis is arranged in parallel, and the power output shaft is connected with jackshaft by first gear pair and jackshaft is driven to rotate, the centre
Axis is equipped with the jackshaft drive pinion being connected with automobile differential, which is characterized in that the output shaft of driving motor, which is equipped with, to be driven
Dynamic motor driving gear, the jackshaft are equipped with the driving motor driven gear being meshed with driving motor driving gear, institute
The diameter for stating driving motor driving gear is less than the diameter of driving motor driven gear, the driving motor driven gear and driving
The gear ratio of motor driving gear is more than the gear ratio of first gear pair.
The ratio of canine tooth tooth number and the pinion gear number of teeth in gear ratio, that is, gear pair.Engine and driving motor in the application
Running car is driven for two power transmission routes and using different speed ratios, i.e. it is defeated that the power of engine passes sequentially through power
Shaft, first gear pair, jackshaft and jackshaft drive pinion are transmitted to automobile differential and carry out power output to vehicle, and drive
Dynamic motor is then transmitted to vapour by driving motor driving gear, driving motor driven gear, jackshaft and jackshaft drive pinion
Vehicle differential mechanism carries out power output to vehicle.And the gear ratio of driving motor driven gear and driving motor driving gear is more than the
The gear ratio of one gear pair, therefore engine is ensure that compared to having lower speed ratio for driving motor, to ensure automobile
Fuel economy when running at high speed.It is straight due to driving motor driving gear simultaneously in the power transmission route of driving motor
Diameter is less than the diameter of driving motor driven gear, forms deceleration mechanism, therefore just can expire using the driving motor of reduced size
The power demand of sufficient automobile, so as to reduce the size of vehicle body.
In the hybrid power system of above-mentioned automobile, shaft and the power output shaft of the driving motor are coaxially disposed.
