In order to make the engine structure compactness, improve the output power of unit weight, reduce oil consumption, people have designed the motor to the top double-piston again, as the utility model people in first to file 01106292.4, a kind of dual-purpose gasoline and diesel oil four-stroke internal combustion engine, by connecting rod, body, distribution device, oil supply system, lubrication system, cooling system, starting arrangement is formed, connecting rod is by piston set, connection rod set, bent axle and flywheel constitute, the cylinder that cylinder sleeve is housed is installed in the body, it is characterized in that: this explosive motor has two cover crank linkage mechanisms, and two cover crank linkage mechanisms are by 3,5 or 7 driving gears connect; Two opposed pistons of installing in the cylinder of every single cylinder, two pistons have identical phase place; The inlet and exhaust valve of distribution device is arranged at the sidewall at cylinder middle part, adopts four-stroke intake and exhaust mode.But owing to two cover crank linkage mechanisms are adopted the mode of gears output, gear former gapped at the stroke that has in fact reduced piston, make the motor to the top double-piston of this structure can not bring into play due benefit, do not reach theoretical design level far away.
Summary of the invention:
The purpose of this utility model---be to provide a kind of novel twin-tub double-piston explosive motor, its reasonable in design, operation steadily, and can simplify motor, reduce processing and maintenance cost.
The utility model provides a kind of twin-tub double-piston explosive motor, form by body, distribution device, oil supply system, lubrication system, cooling system, starting arrangement, the cylinder that cylinder sleeve is housed is installed in the body, it is characterized in that: this explosive motor has several cylinder group; There are two to become countercylinder in each cylinder group, installing two opposite pistons (1) in the cylinder of every single cylinder (5); Two cover linkage mechanisms are arranged in each cylinder group, and linkage mechanism is made of pitman shaft (2), connecting rod (3), and two cover linkage mechanisms are opposite to two two ends that become countercylinder, and are connected on the common output crank shaft (4) by connecting rod (3) respectively.
In the utility model twin-tub double-piston explosive motor, two the paired pistons (1) in described every single cylinder (5) are staggered relatively, and phase place is identical.
In the utility model twin-tub double-piston explosive motor, two cover linkage mechanisms in described each cylinder group, two connecting rods (3) of linkage mechanism, their end are connected on the different shaft parts of output crank shaft (4), and the other end is connected respectively on two pitman shafts (2) of two cover linkage mechanisms.
In the utility model twin-tub double-piston explosive motor, described two cover linkage mechanisms have corresponding two pitman shafts (2) to be connected respectively on the piston (1) and connecting rod (3) of two one-tenth countercylinders (5) in the same cylinder group.
In the utility model twin-tub double-piston explosive motor, the one-tenth countercylinder in the described same cylinder group has a shared output crank shaft (4), the shared output shafts of a plurality of associated cylinder groups (4) of same motor.
In the utility model twin-tub double-piston explosive motor, described motor has 1 or a plurality of cylinder block, forms twin-tub or multi-cylinder internal combustion engine that total number of cylinders is an even number.
Described in the corresponding background technique, double-piston explosive motor described in the utility model has following advantage:
1, structural design compactness is selected cylinder co-ordination in groups for use, compares with in-line arrangement or V-type cylinder engine, and when output power was identical, the weight of himself was the lightest, and promptly the output power height of unit weight is particularly suitable for as automobile power machinery.
2, owing to all select two pistons of paired anti-phase placement in every single cylinder for use, and the use of connecting rod and pitman shaft considered stress equalization, thereby improved the continuity of engine power, improved the motor traveling comfort.
4, double-piston internal-combustion engine function free arrangement cylinder described in the utility model, and the production of motor is easy to realize modularization, is convenient to carry out the Transform Type design of product and exploitation once more.
5, related connecting rod can reduce resolution of forces better in the utility model, and can simplify motor, reduces processing and maintenance cost.
