Abstract

The utility model relates to a double propulsion unit for the vehicle with two engines. The utility model is characterized in that through a linked machine or a changing machine, an auxiliary machine with a clutch and a host machine without a clutch are connected together to form a double propulsion unit to substitute a single motor to connect with and drive an automobile chassis; operating the clutch of the auxiliary machine or clutches of both the changing machine and the auxiliary machine can dispatch two full throttle power of the host machine or the auxiliary machine to adapt to two power requirements under two loading conditions of empty loading and full loading or under two driving speed requests of slow run in city and high run outside city; therefore, the utility model can raise load rate of engines, save fuel oils, and the fuel saving ratio can reach 25%-35%.

Description

Double propulsion unit for the vehicle with two engines

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

Satisfying under the requirement of tractive performance, the gross horsepower unmodified prerequisite, change a monomotor into two driving engines, and need select the service condition of driving engine for use by running car, 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, carry 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 is based on Domestic Automotive Industry, and 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 to adopt online device or the device of changing planes is not linked together a subsidiary engine that has a simple power-transfer clutch and one with the main frame of power-transfer clutch, form dual powerplant, substitute the monomotor connection and drive car chassis.Change planes device and subsidiary engine power-transfer clutch of actuating subsidiary engine power-transfer clutch or 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 (at a high 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.Can be used for not having air pump, light-duty following passenger vehicle, lorry.The urban transit bus that can not be used for the frequent conversion driving engine of needs service condition.

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

Maybe can throw off by online device normal engagement, gear-driven with the subsidiary engine 2 of simple clutch 3 and main frame 1 with changing planes, the gear-driven device 4 of changing planes is linked togather, form double motor equipment A, through the gearshift of chassis B with simple clutch 5, transmission simple transmission 6 ... until wheel.

The utility model is divided into two types, i.e. online type and the type of changing planes. Online type by the subsidiary engine clutch from changing planes with incompatible, thereby participate in or do not participate in driving. Clutch is often to separate, and the release bearing wearing and tearing are big, and the life-span is short. Change planes type when changing planes, and first cut-off clutch, conversion subsidiary engine are changed planes after the joint or disengaged condition of gear, clutch are engaged again. 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. But the device of changing planes is more complicated than online device structure.

Main and auxiliary engine of the present utility model can be various types of engines: gasoline engine, diesel engine, rotary engine ..., or even compound. The ratio of main engine power and power for auxiliary machinery (power-division ratios) is influential to oil-saving effect. Optimal power contribution is than 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. Main and auxiliary two engine arrangement directions can adopt in the same way, reverse or be mutually tilting; Before also can one, one arrange rearly; In case of necessity, two engines can be attached together in a body. Subsidiary engine clutch or main frame or both can connect with online device or the device of changing planes by power transmission shaft.

Good effect of the present utility model is fuel-economizing significantly.And, simple in structure.Can be used for not having air pump, light-duty following passenger vehicle, lorry.The fuel saving ratio of the twin engine vehicle of this purposes reaches 25%～35%.

Fig. 2 for be used for light bus, before one, a rear layout, the double motor equipment schematic diagram. It is embodiment of the present utility model.

2 is subsidiary engine, and 3 is the subsidiary engine power-transfer clutch.They can be contained between two front-wheels or below the seat parallel with operator's saddle.Main frame 1 can be contained in automobile middle part or near the place of trailing wheel.The online device or the device 4 of changing planes can be placed in below last arrange seats.Main frame 1, subsidiary engine 2 connect with the online device or the device 4 of changing planes by transmission shaft 7.5 and 6 are respectively the power-transfer clutch and the change-speed box on chassis.

The transmitting ratio online or gear of changing planes should guarantee the collaborative running of the main and auxiliary machine of different rated speed of rotation, also will coordinate to change the driving engine of joining and the rotating speed contradiction between the chassis.
