Abstract

The utility model relates to a dual motive power device for a dual engine automobile. The utility model is characterized in that through a linked machine or a changing machine, two engines with clutches are connected together to form dual motive power device to substitute the single motor to connect and drive the automobile chassis without clutches; operating the clutches of the two engines or clutches of both the changing machine and the two engines can dispatch two full throttle power of the host machine or both auxiliary machine of the host machine, or three full throttle power of small or big machine or both machines to adapt to power requests in different running conditions; therefore, the dual motive power device for a dual engine automobile can raise load rate of engines, and save fuel oils with 25%-40% fuel saving ratio.

Description

Dual motive power device for dual engine automobile

The utility model relates to a kind of twin engine vehicle dual powerplant.

Satisfying the requirement of tractive performance, under the gross horsepower unmodified prerequisite, changing a monomotor into two driving engines, and need select the service condition of driving engine for use, just can improve the rate of load condensate of driving engine, thereby saving fuel oil by running car.

At present, the Germany a kind of two-engined urban transit bus sample car occurs and (sees " external automobile " second phase in 1987: " the urban transit bus transmission system of nineteen ninety " literary composition).It is to reequip to design on the car prortotype basis of self-acting clutch and automatic transmission with hydraulic torque converter, and carries out comprehensive system controlled by computer.This scheme is not suitable for Domestic Automotive Industry present level and development condition.

The purpose of the twin engine vehicle that the utility model is spoken of also is fuel-economizing; And, be based on Domestic Automotive Industry.Design or repacking design on the car prortotype basis of simple power-transfer clutch, simple transmission.And the structure of the earlier online back of employing speed change is shifted gears by chaufeur.Like this, need system controlled by computer.

The technical solution of dual powerplant described in the utility model is: by the online device or the device of changing planes the driving engine of two band power-transfer clutchs is associated in together, forms dual powerplant, substitute monomotor and connect and drive not chassis with power-transfer clutch.The change planes power-transfer clutch of device and two driving engines of the power-transfer clutch of actuating two driving engines or actuating, can select for use main frame or main frame to add two kinds of driving engine running conditions of subsidiary engine, add two kinds of full throttle power of subsidiary engine or select for use little machine, big machine or two machines to move three kinds of driving engine running conditions simultaneously thereby send main frame or main frame, move three kinds of full throttle power simultaneously to adapt to the power requirement under the different driving conditions thereby send little machine, big machine or two machines.Therefore, can improve the rate of load condensate of driving engine, save fuel oil.

Dual powerplant described in the utility model does not need auto-control, and is simple in structure.Can be used for not having air pump, light-duty following passenger vehicle, lorry.Can not be used for the often urban transit bus of conversion driving engine service condition.

Fig. 1 be dual powerplant described in the utility model structure and with the block diagram that concerns on chassis.

Two driving engines 1 and 2 devices 5 of changing planes that maybe can throw off by online device constant-mesh, gear-driven, gear-driven with power-transfer clutch 3 and 4 are associated in together respectively, form dual powerplant A, through not with the gearshift of the chassis B of power-transfer clutch with simple transmission 6 ... reach wheel.

The utility model is divided into two types, the promptly online type and the type of changing planes.Online type by two power-transfer clutchs from changing planes with incompatible, thereby participate in or do not participate in driving.Power-transfer clutch is often to separate, and the release thrust bearing wearing and tearing are big, and the life-span is short.Change planes type when changing planes, first cut-off clutch, conversion is changed planes after the joint or disengaged condition of gear, engages the clutch again.At this moment, power-transfer clutch only separates in the moment of changing planes, and is normal the joint, and the release thrust bearing wearing and tearing are little, and the life-span is long.But the type of changing planes is more complicated than the structure of online type.

Two driving engines of the present utility model can be various types of driving engines: spark ignition engine, diesel engine, rotating combustion engine ..., or even compound.The ratio of two engine powers is influential to oil-saving effect.Best power ratio is difference with driving engine service condition number, engine type and automobile purposes.Have under the condition of two kinds of driving engine service condition by maneuvering system control, when two driving engines are all piston engine, when being used for light-duty following lorry, main engine power should be more bigger than power for auxiliary machinery; When being used for medium-sized or above lorry and passenger vehicle, main engine power is smaller.Main and auxiliary acc power is than between 0.7～1.4, have under the condition of three kinds of driving engine service condition by maneuvering system control, when two driving engines are all piston engine, city motor bus two acc power ratios should be 0.5～0.6, lorry is 0.6～0.8, and small passenger car is 0.4～0.5.Two engine position directions can be in the same way, oppositely directed or mutually tilting; Before can one, one afterwards arrange; In case of necessity, two driving engines can be attached together in a body.Arbitrary power-transfer clutch or both can connect with the online device or the device of changing planes by transmission shaft.The online device or the device of changing planes can attach together within a housing with the change-speed box on chassis, even the online device or the device of changing planes can attach together within a housing with the change-speed box and the diff on chassis.This measure can be simplified the structure of automobile widely.

Good effect of the present utility model is fuel-economizing significantly, and fuel saving ratio reaches 25%～40%.And structure is very simple.Can be used for not having air pump, light-duty following passenger vehicle, lorry and small passenger car.

Embodiment of the present utility model is as follows.

Fig. 2 is that the change-speed box on driving engine reversed arrangement, online device or change planes device and chassis and diff attach together the dual powerplant scheme drawing within a housing.

Two driving engines 1 and 2 that have power-transfer clutch 3 and 4 are respectively connected by the online level or the level 5 of changing planes, and power is reached speed change level 6 and differential level 7, reach left and right two-wheeled by axle drive shaft 8 again.Such axle drive shaft leaf breakaway-element axle drive shaft is applicable to independent suspension and F/F, f-w-d or rear-mounted engine.The automobile of back-wheel drive.

When present embodiment was used for small passenger car, dual powerplant was placed on after the front-wheel.At this moment, forward and backward wheelbase is bigger, and center of gravity is more moderate, can obtain ride comfort preferably, make take stable comfortable.
