Background technology
At present, the fuel-economy performance of hybrid vehicle is high, and rideability is superior, and the driving engine of hybrid vehicle will use fuel oil, and when starting to walk, accelerating, owing to there being the auxiliary of electro-motor, so can oil consumption be reduced.At present, oil and electricity hybrid vehicle is divided into series, parallel and series-parallel connection three kinds of structure types.
" series system ", only with the electronlmobil that electrical motor driven travels, driving engine is only as propulsion source, and automobile only travels by electrical motor driven, and drive system is electro-motor.Cascaded structure is arranged simple, but driving efficiency is too low.
" parallel way " is active force with driving engine, and electro-motor is as auxiliary power.This mode mainly travels with engine drive, utilize electro-motor to have restart time produce the feature of very strong driving force, when the consumption of the engine fuel such as vehicle starting, acceleration is larger, reduce the oil consumption of driving engine by the mode of electro-motor assistive drive.This mode relatively simple for structure, only needs on automobile, increase electro-motor and storage battery.
Only travel by electrical motor driven when " series, parallel hybrid mode " startup and low speed, when speed improves, jointly power is shared efficiently by driving engine and electro-motor, hybrid connected structure overcomes the shortcoming of series and parallel connections, good combination property, but this mode needs power sharing device and electrical generator etc., therefore complex structure.
Because the driving efficiency of parallel way is high, structure is simple, therefore has a wide range of applications occasion.Existing Parallel hybrid power transmission, because driving engine and drive wheel adopt mechanical connection, can not control the economic work rotating speed of driving engine.Therefore, when city operating mode, driving engine always can not operate in optimal working point, and the fuel economy of vehicle is than poor during series connection.
Summary of the invention
The purpose of this utility model is to overcome existing deficiency in the art, provides a kind of mechanical efficiency improving hybrid power transmission system, the Parallel hybrid power transmission used for buses of Fuel Economy the best when realizing driving operating mode.
The utility model solves its technical matters and is achieved through the following technical solutions:
A kind of Parallel hybrid power transmission used for buses, be made up of main transmission box and secondary transmission case, main transmission box often engages dead axle transmission mechanism by main tank housing and the full helical teeth of triple axle be installed in main tank housing and main tank shifting operation mechanism is formed, the full helical teeth of triple axle often engages dead axle transmission mechanism and comprises an axle, two axles, tween drive shaft and transmission gear at different levels, secondary transmission case comprises odd-side housing, it is characterized in that: Spiral Bevel Gear Transmission mechanism is installed in odd-side housing, this Spiral Bevel Gear Transmission mechanism is by the basin tooth being installed on two axle mouths, the angle tooth engaged with this basin tooth and supporting seat are formed, angle tooth is coaxially fixedly mounted with rotating shaft, supporting seat is fixedly installed in odd-side housing, rotating shaft is installed on supporting seat by bearing, rotating shaft lower end is stretched out outside odd-side housing.
And the rotating shaft lower end that described angle tooth is fixedly mounted with is connected with motor output shaft.
And, described supporting seat by be positioned at tooth top, angle a upper support seat and be positioned at tooth bottom, angle a midship mounting seat and once supporting seat form.
Advantage of the present utility model and beneficial effect are:
1. a Parallel hybrid power transmission used for buses, adopt spiral bevel gear vertical transmission mechanism, under driving operating mode, for target, power division is carried out to driving engine and motor so that Fuel Economy is best, advanced by motor, engine moment couple drive vehicle; Its driving engine and electrical motor can drive automobile can drive separately again jointly, and driving engine and electrical motor adhere to two cover systems separately, separately can provide moment of torsion to automotive transmission; When vehicle start for reducing exhaust emissions driving engine and mis-fire, but use electric energy to drive vehicle to advance by angle tooth, when automobile accelerates climbing, electrical motor and driving engine can provide power to transmission device simultaneously, once automobile speed reaches cruising speed, automobile will only rely on driving engine to maintain this speed.Electrical motor not only can make electrical motor but also can do electrical generator use, with the load suffered by balanced engine, in high efficiency region work, effectively can realize energy-conserving and environment-protective.
2. a Parallel hybrid power transmission used for buses, the motor being connected to angle tooth during braking serves as electrical generator recovery braking energy and is stored in closed-centre system, now motor plays the effect of braking, function class is similar to retarder, it had both reclaimed vehicle braking energy, reduce vehicle oil consumption, additionally reduce the abrasion of car brakeing sheet.
3. a Parallel hybrid power transmission used for buses, the supporting seat of its angle tooth by be positioned at tooth top, angle a upper support seat and be positioned at tooth bottom, angle a midship mounting seat and once supporting seat form, employing straddle type mounting means, solution angular wheel shaft transmission rigidity is poor, shake serious problems.
4. the utility model scientific structure design is reasonable, best for target with Fuel Economy under driving operating mode, power division is carried out to driving engine and motor, advanced by motor, engine moment couple drive vehicle, driving engine and electrical motor can drive automobile can drive separately again jointly, improve the mechanical efficiency of hybrid power transmission system, good realizes energy-conserving and environment-protective, has reliable and stable advantage simultaneously.
