Description
Technical field the utility model relates to a kind of motor, especially has the multi-cylinder hypocycloid mechanism internal-combustion engine of auxiliary output shaft structure.
The background technique multi-cylinder engine is mainly used on train, automobile, the steamer.The setting type of the cylinder of internal-combustion engine that 6 cylinders are following is generally in-line arrangement.Each cylinder all comprises parts such as cylinder body, piston and connecting rod.Piston to-and-fro motion in cylinder body in each cylinder, the merit that each piston is done is delivered on the same bent axle by connecting rod, exports by reducing gear again.Hypocycloid mechanism internal-combustion engine is that to utilize the hypocycloid of circle be the principle of straight line when special parameter (moving circle radius r equals 1/2 and decides circle radius R), and the linear reciprocating motion of piston is converted to rotatablely moving of bent axle.Wherein, decide circle and can be designed to a ring gear, moving circle can be designed to a planet gear, and the straight pin of the design one connection connnecting rod big end parallel with gear shaft can be realized two kinds of conversions between the motion on the planetary pinion circumference.
Hypocycloid form mechanical structure is proposed by people such as Huf.Franz the earliest.Therefore hypocycloid mechanism internal-combustion engine does not exist side pressure during pistons work in theory because connecting rod the time is not swung in work, and this will reduce the loss of mechanical friction merit and because the running vibration that tilting moment causes of internal-combustion engine greatly.But every section output shaft of hypocycloid multi-cylinder engine is independently, can't obtain whole output works from an end of internal-combustion engine.Although obtain integrated torque after the moment of torsion that adopts special entity hypocycloid mechanism respectively can be exported shaft part synthesizes, can make complex structure, the entire length of internal-combustion engine is strengthened.Also there are some difficulties in hypocycloid mechanism on assembling and processing technology in addition, needs be installed on the dividing plate of body by screw and locating stud as bull gear, and its installation precision and installation strength are difficult for guaranteeing; Can cause the Gear Processing difficulty when planetary pinion and output shaft are made of one, because the output shaft crank is an overhang supports, how installation strength between gear and the wheel shaft and rigidity guarantee etc. it all is masty problem during separate machined.Therefore, present structure can't realize hypocycloid mechanism internal-combustion engine high-efficient operation.
Chinese patent CN2890371 number disclosed " motor buffering output shaft device " patent (application number: 200620055324.6), be by engine output shaft, locking nut, bearing, plug screw, bevel gear, the power transmission dog, spring seat, spring, bearing support is formed, the bevel gear sky is enclosed within on the engine output shaft, and the power transmission dog is connected with spline with engine output shaft, and spring seat is installed on the output shaft of motor, spring is installed between power transmission dog and the spring seat, and the end cam of power transmission dog contacts with the interior edge face cam of bevel gear.The deficiency of this patent is: just have certain cushioning effect, can not reduce the problem that there is the output work loss in hypocycloid mechanism, realize hypocycloid mechanism internal-combustion engine high-efficient operation.
Chinese patent CN1959088 number disclosed " variable-displacement multicylinder engine system " patent (application number: 200610039007.X), be to connect solid electrically controlled gas valve executing mechanism on each cylinder, the clutch end place establishes solid speed probe and torque transducer, torque transducer and speed probe connect the input end of ECU (Electrical Control Unit) (ECU), the output of ECU (Electrical Control Unit) (ECU) connects the electromagnetic coil in the electrically controlled gas valve executing mechanism, under the support of related software, ECU (Electrical Control Unit) can calculate power demand according to transducing signal, the number of cylinders that the multicylinder engine of commander's control in real time system works is to reach the coupling of power demand and output power.The deficiency of this patent is: sensor and automatically controlled device can reduce the output work loss by the change of displacement volume, but still can't solve the problem that there is the output work loss in hypocycloid mechanism from structure, realize hypocycloid mechanism internal-combustion engine high-efficient operation.
The summary of the invention the purpose of this utility model is exactly that a kind of multi-cylinder hypocycloid mechanism internal-combustion engine with auxiliary output shaft structure will be provided, and solves the problem that there is the output work loss in hypocycloid mechanism from structure, realizes hypocycloid mechanism internal-combustion engine high-efficient operation.
In order to achieve the above object, the multi-cylinder hypocycloid mechanism internal-combustion engine with auxiliary output shaft structure that the utility model provides is except having cylinder body, piston, connecting rod, planetary gear set and output shaft, also has auxiliary output shaft structure, wherein, position between cylinder body, piston, connecting rod, planetary gear set and the output shaft and kinematic relation are prior art, repeat no more here; Auxiliary output shaft structure is made up of driving gear, driven gear and auxiliary output shaft; Auxiliary output shaft and output shaft are arranged in parallel; Driving gear has a plurality of, and driving gear is fixed on the output shaft, and driving gear is distributed in the both sides of connecting rod; Driven gear has identical quantity with driving gear, and driven gear is fixed on the auxiliary output shaft; Driving gear and driven gear correspondence in twos arrange in pairs or groups together that formative gear is connected.When the utility model uses, after each piston merit that to-and-fro motion is done in cylinder body is delivered to output shaft on the internal-combustion engine, again by driving gear and driven gear in twos the correspondence formative gear of arranging in pairs or groups together be connected and be delivered on the auxiliary output shaft, can solve the problem that there is the output work loss in hypocycloid mechanism, realize hypocycloid mechanism internal-combustion engine high-efficient operation.
