Abstract

The utility model provides a two stroke double rocker arm type rotary engine, composed of a cylinder block, a main shaft, a cylinder cap, rocker arms, rocker shafts, seal assemblies and general purpose systems of fuel, ignition and start of a piston engine. The utility model is provided without connecting rods and various bearing shells, and the moving components are fewer. When running, every moving component is in symmetrical balanced state, and the vibration is small. The cylinder block forms a symmetrical frame box, and the main shaft is installed in the center. The two cylinders respectively work in two cycles at every rotating cycle of the main shaft. Thus, the power is greater than the power of piston engines with the same discharge capacity, and structural and operating performances are better than piston type and Wankel engines. The two stroke double rocker arm type rotary engine is particularly suitable for motorcycles, cars, tractors, ships and other mobile machines.

Description

Two stroke double rocker arm type rotary engine

The utility model relates to a kind of rotary engine, is specially adapted to movable type mechanical: fields such as motorcycle, automobile, tractor, steamer, excavation machinery.

General reciprocating engine commonly used, its reciprocating inertial force has hindered the raising of reciprocating engine power and efficient, and complex structure, and amount of parts is many, and when running up, movement parts such as piston ring and distribution device break down easily.At the initial stage in the sixties, wankel (Wankle) triangle piston circulating engine occurred, and once once produced in batches, but because piston-deflection still produces vibration, and makes machine oil easily scurry in the cylinder, must set up grease proofing device, thereby make mechanism complicated.In addition, its apex seal itself swing, seal arrangement can only be the line contact, easily produces drawback such as collaborate, its structure is unsatisfactory.The seventies initial stage, newpapers and periodicals were not once led several rotary engines, develop the rotary engine of various different structures, but the report of success is not all arranged so far in respect of peace Buddhist nun's dyne (Anidyne) Lai Kesi (Ryenco) of the U.S., the clarks (Ciarke) of Britain, the He Fu (Huf) of federation of Germany, the uncommon people such as (Sarich) in Australian Surrey.

The purpose of this utility model provides the two rocking arm type rotary engines of a kind of two-stroke, and it both can avoid the reciprocating inertial force of reciprocating engine, and was more superior than Wankel engine structure again, is used for every field to replace piston type gasoline (diesel oil) machine.

The utility model is achieved in that this machine oil cylinder body, main shaft, rocking arm, pitman arm shaft, cylinder cap and six component of black box, and with the general fuel delivery of reciprocating engine, ignition system, flywheel, pay composition such as machine.Two rocking arm symmetric arrangement are done about swing, act ons identically with the piston of reciprocating engine, and drive has the main axis rotation of symmetrical cam and output power.During work, the position of two rocking arms, slew rate, pressure of standing etc. are in symmetry status fully, do not need to add in addition Equilibrator.

Below with reference to accompanying drawing model utility is described in further detail.

Fig. 1,2,3, the 4th, main structure of this machine and working principle schematic representation.

Fig. 5 is the cylinder body sketch, and secondary Fig. 5-2,5-3 are A-A and the B-B sectional drawings of master map 5-1

Fig. 6 is the main shaft sketch.

Fig. 7 is the cylinder cap sketch.

Fig. 8 is the rocking arm sketch.Accompanying drawing 8-2,8-3 are 8-A and the B-B sectional drawing of master map 8-1

Fig. 9 is the black box schematic representation.

With reference to Fig. 1 and 5, cylinder body (1) is the frame case of a symmetric shape, and main shaft (2) is installed at the center, is supported by the rolling bearing on the cylinder cap (3).Main shaft (2) turns clockwise, and two rocking arms (4) are around pitman arm shaft (5) external symmetry swing inwards.When main shaft (2) was in Fig. 1 position, port K1 and K2 were all blocked by rocking arm (4), and scavenging air belt S1 and S2 are cut off by apex seal, and compression stroke begins, and rocking arm is outwards swung; When main shaft (2) is in Fig. 2 position, compression stroke is near ending, the inlet hole conducting, owing to form partial vacuum in the cylinder body (1), incoming mixture enters its inside, and spark plug R discharge or oil are chewed oil spout, and the pressurized gas in the cylinder body (1) force rocking arm (4) to be swung inwards, drive main shaft (2) and rotate to Fig. 3 position, this is power (work) stroke.Port, scavenging air belt still are in and close or the partition state at this moment.When main shaft (2) is in Fig. 4 position, inlet hole is plugged, exhaust port communicates with atmosphere earlier, the interior combustion gas of cylinder body (1), scavenging air belt is conducting subsequently, and incoming mixture enters, be that exhaust, air inlet and scavenging are carried out simultaneously, when main shaft (1) transferred back to Fig. 1 position, new work cycle began, and so went round and began again by main shaft (2) output power and moment of torsion.

With reference to Fig. 6, have a symmetrical cam on the main shaft (2), play the connecting rod effect.The pin P at cam end angle plays piston and acts on slightly.

With reference to Fig. 8, rocking arm (4) is made up of aluminum alloy (L) and alloyed steel (G), and curve bath T has cooperated piston action with sub-slightly P on the main shaft (2).

With reference to Fig. 9, black box has: end sealing strip (8), end sealing strip back of the body spring (9), apex seal (10), apex seal back of the body spring (11), sealing Xiao (12), sealing Xiao's stage clip (13).

As mentioned above, the utility model does not have uneven movement parts, vibrates little; No connecting rod and various bearing shell, moving parts is few, and is simple and compact for structure.Main shaft (2) whenever circles 360 °, and cylinder promptly has two work cycle, so the power of output and moment of torsion are greater than the reciprocating engine with discharge capacity.Moreover apex seal (8) contacts with cylinder body (1), cylinder cap (3) face of being with end sealing strip (10), and excellent sealing performance is arranged.All part does not have specific (special) requirements to material and processing technology, and easily manufactured, cost is low.Cylinder body (1) and cylinder cap (3) can be made into the foundry goods or the weldment of water jacket or fan blade.Rocking arm is available water or air cooling also.

Slave of the present utility model and auxiliary equipment: fuel system, igniter, starting device etc. all can be applied mechanically piston-mode motor. Because two cylinders produce power stroke simultaneously, so will dispose heavier flywheel.

Weigh from its structure and service behaviour aspect, the utility model is more superior than piston type and Wankel engine, substantial progress is arranged, and can be applicable to every field, is specially adapted to movable type mechanical.
