Abstract

The utility model relates to a two-engine double-power device for vehicles. The utility model is characterized in that through a changing machine or not through a changing machine, an auxiliary machine with a clutch and a host machine without a clutch are directly connected together on the host head-end area to form a double-power device substituting a single motor to connect with and drive an automobile chassis; operating the clutches of the changing machine and the auxiliary machine or the clutch of the auxiliary machine can dispatch two full throttle power of the host machine or both the host machine and the auxiliary machine to adapt two power requirements under two loading conditions of empty loading and full loading or under two driving speed requests of slow run in the city and high run outside the city; therefore, the utility model can raise the load rate of engines, and save fuel oil with 25%-35% fuel saving ratio.

Description

Two-engine double-power device for vehicles

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, change a monomotor into two driving engines, and need select the service condition of driving engine by running car for use, just can improve the rate of load condensate of driving engine, thereby save fuel oil.

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, do not need system controlled by computer.

The technical solution of dual powerplant described in the utility model is by changing planes device or directly is not cascaded at main frame front end place with the main frame of power-transfer clutch with the subsidiary engine of simple power-transfer clutch and by the device of changing planes, form dual powerplant, substitute the monomotor connection and drive car chassis.Change planes device and subsidiary engine power-transfer clutch or actuating subsidiary engine power-transfer clutch of actuating can send main frame or main frame and add two kinds of full throttle power of subsidiary engine to adapt to zero load, fully loaded two kinds of load-up conditions down or two kinds of power needs under city (low speed), city outer (from speed) two kinds of speed of a motor vehicle requirements, thereby can improve engine load rate, save fuel oil.

Dual powerplant described in the utility model does not need auto-control, and is simple in structure.But can not coordinate to change the driving engine of joining and the rotating speed contradiction between the former chassis, only be applicable to the supporting design conditions in main and auxiliary driving engine and chassis or change the main and auxiliary engine governed speed of joining and former chassis is complementary or near the design conditions of coupling, can be used to not have light-duty following passenger vehicle, the lorry of air pump.The city motor bus that can not be used for the frequent conversion driving engine of needs service condition.

The utility model is divided into two types, promptly band change planes device and not with the device of changing planes.

Fig. 1 be band change planes device dual powerplant structure and with the block diagram that concerns on chassis.

Fig. 2 be not with the device of changing planes dual powerplant structure and with the block diagram that concerns on chassis.

Subsidiary engine 2 is by changing planes with simple clutch 3 and the device 4 (Fig. 1) or connect the front end of main frame 1 by changing planes with simple clutch 3 (Fig. 2) of changing planes, form two power set A, the gearshift that connects again chassis B is with simple clutch 5, transmission simple transmission 6 ... until wheel.

Not with two power set of the device of changing planes by the subsidiary engine clutch from changing planes with closing, thereby participate in or do not participate in driving. It is simple in structure, but clutch is often to separate, and the release bearing wearing and tearing are big, and the life-span is short. And band is changed planes two power set of device when changing planes, first cut-off clutch, conversion change planes gear by close or the disengagement state after, again clutch is engaged. Like this, clutch only separates in the moment of changing planes, and is normal the joint, and the release bearing wearing and tearing are little, and the life-span is long. If the rated speed of main and auxiliary machine is not identical, the device gear of changing planes can also be coordinated its rotating speed to reach the effect of giving full play to two engine powers and reducing oil consumption.

Main and auxiliary machine can be various types of engines, but for not with the situation of the device of changing planes, both rated speeds should equate or approach; The ratio of main engine power and power for auxiliary machinery (power-division ratios) is influential to the fuel-economizing effect. Best power-division ratios is with engine type and automobile purposes and difference. When two engines are all piston-mode motor, when being used for light-duty following lorry, main engine power should be more bigger than power for auxiliary machinery; When being used for light-duty following passenger vehicle, main engine power is smaller. Main and auxiliary acc power is than between 0.7～1.4, changes planes between device and the main frame or should join between subsidiary engine clutch and the main frame with power transmission shaft or shaft coupling; In case of necessity, main and auxiliary machine also can attach together within a body.

Good effect of the present utility model is significantly fuel-economizing. And, simple in structure, be applicable to that main and auxiliary engine and front yard coil supporting design situation or change that the main and auxiliary rated engine speed of joining mates mutually with former chassis or approach the design situation of coupling, can be used for no air pump, passenger vehicle, lorry below light-duty. The fuel-economizing rate of the twin-engined automobiles of this kind purposes reaches 25%～35%.

Below in conjunction with accompanying drawing embodiment of the present utility model is narrated.

Fig. 3 for by propeller shaft couplings, not with two power set schematic diagrames of the device of changing planes.

Fig. 4 for connected by shaft coupling, not with two power set schematic diagrames of the device of changing planes.

The purpose of embodiment is: a monomotor is driven automobile change two the engine-driven automobiles of cylinder number for half into.As: change a four-cylinder diesel engine into two two-cylinder diesels, or a two-cylinder diesel changes two single cylinder diesels into.Like this, two engine speeds are identical, and are the same with former driving engine; The rotating speed on nature and former chassis also mates.

If desired two driving engines are placed in two places of a segment distance, then should connect by transmission shaft 7 between two driving engines, as Fig. 3, if two driving engines tightly are associated in together, then should connect by coupler 8 between two driving engines, as Fig. 4.

For subsidiary engine is connected on the main frame, host aspect should be done some change.As fan and belt pulley 9 will be toward on one side (upwards or to left and right both sides) remove, as shown in Figure 3, Figure 4.

The power-transfer clutch 5 that the main frame back is connected is the gearshift power-transfer clutchs on former chassis.The 6th, change-speed box.
