Abstract

The utility model relates to a motor vehicle and particularly relates to a rotor engine for a motorcycle. The utility model is provided with a cylinder, wherein, the front and the rear parts are provided with cylinder covers, and a triangular piston rotor rotating in the cylinder. A piston of the triangular piston rotor is supported on a pinion which is arranged on an eccentric shaft and is engaged with an inner gear ring. The matching structure of the inner cavity type surface of the cylinder and the triangular piston rotor type surface is formed in a mode that a circle making radius R which is equal to forty-nine, an eccentricity e which is equal to seven and a top circular arc radius a which is equal to two are calculated by the rotation wheel curve formula to form a picture. Accordingly, the rotor engine formed in the mode has the advantages of compact structure, light weight, small size and less harmful ingredient of exhaust gases and is particularly suitable for the motorcycle having horsepower of four to ten.

Description

Be used for the particularly rotary engine of motorcycle of Motor Vehicle

The utility model relates to and is used for the particularly rotary engine of motorcycle of Motor Vehicle.

Be used for the CO of the rotary engine of Motor Vehicle than transmission Reciprocating engine exhaust emissions ₂And NO ₂Low by 1/3, in light weight 2/3, overall volume is little by 2/3, and part sum and motion number of packages are few 1/2, advantages such as oil consumption province, make have more than 100 year historical Reciprocating engine might be progressively by its replacement.Especially the CH that rotary engine is high slightly can make CH in outlet pipe _xReach purification with air burning, thereby become present comparatively ideal environment protecting type engine.The attention and the application of external more than ten production firms of national tens of family have been caused.Rotary engine is because of seeming easy, actual complex, the reason that technical requirements is high, the domestic manufacturing that manufacturer production is seldom arranged or introduce rotary engine.And the key problem in technology of manufacturing rotary engine is a cylinder block and the tight coordination and appropriate the cooperating of piston rotary spinning roller curved surface.And appropriate cooperate degree mainly is the ever-changing of its spinning roller curve and quite complicated designing and calculating.In case the incorrect cooperation of the spinning roller curve that calculates must cause the compression ratio of motor to descend, oil gas can not fully burn, and noxious gas emission increases, and noise increases, the bad result that power descends.

The purpose of this utility model provides a kind of rotary engine cylinder block and piston spinning roller curved surface of making and cooperates appropriately, and profile cooperates rotary engine accurately and reliably.

Technical solution of the present utility model is: be used for the particularly rotary engine of the motorcycle triangular-piston rotor 2 that has that the cylinder body 1 of cylinder cap is equipped with in front and back and rotate in cylinder body 1 of Motor Vehicle, triangular-piston rotor is bearing on the small gear 6 on the eccentric shaft 5, small gear 6 is meshed with ring gear 3, its special way is by wound circle radius R=49mm, three parameters of eccentric distance e=7mm and diaphragm seal 9 top radius of arc a=2mm, by cylinder body spinning roller curve equation: The cylinder body profile made from by three-apexed rotor piston rotary spinning roller curve equation:

The three-apexed rotor piston-type surface of the making formation rotary engine that matches.

The utility model is by R=49mm, e=7mm, and the long axis length ρ 1 of the cylinder body spinning roller curve that three calculation of parameter of a=2mm are produced can be 116mm, minor axis length ρ 2 can be 88mm.

The utility model is by R=49mm, e=7mm, and the distance L 1 of spinning roller curve from the limit to the drift angle that three parameter designing of a=2mm are calculated the triangular-piston rotor of making can be 88mm, triangle heart O can be 37mm to the distance L 2 on limit.

Because two spinning roller curves have constituted the minimum area F=F1+F2 that piston contacts with cylinder body, make compression ratio

Thereby guaranteed the perfect combustion of oily vapour, oil consumption is few, and noise is little, and power increases, and has reduced discharge of harmful gases effectively.The appropriate cooperation of cylinder body and piston spinning roller curve and combination accurately and reliably not only make the rotary engine structure compactness, and volume is little, and is in light weight, but also provide bigger design freedom for the shortening of vehicle body and the increase of carriage box volume capacity.

Following accompanying drawing has been described an embodiment of the present utility model.

Fig. 1 is positioned on the interior topology view of cylinder body for the utility model triangular-piston rotor.

Fig. 2 is the spinning roller curve synoptic diagram of the cylinder body die cavity of the utility model three-apexed rotor piston.

Fig. 3 is the shape schematic representation of the utility model triangular-piston rotor.

Fig. 4 pacifies the into interior shape schematic representation of cylinder body for the utility model triangular-piston rotor.

Fig. 1 has described the rotary engine that is assembled by the machining manufacturing, and wherein cylinder body has the fixing pin 7 of several each intervals and is positioned at same clamping bolt 8 of taking turns on week on wheel week.Spark plug 4 is platinum ignition mechanisms of the prior art among the figure.Small gear 6 is fixed on the cylinder body 1 and does not rotate.Triangular-piston rotor 2 is bearing on the axle journal of eccentric shaft 5 and ring gear 3 is housed with small gear 6 engagements and rotate, and forms triangular-piston rotor and does planetary motion around small gear.Prototype of the present utility model is derived from West Germany's Wankel engine, so the black box in this motor, the gas sealing system of piston, frizing and bearing combination, ignition mechanism enclosing cover, flywheel, oil inlet pipe, (not shown) such as balancer weight and prior art are basic identical.Cylinder body and wherein triangular-piston rotor 2 peace advance the e value that occurs in the cylinder body 1, the radius of arc a value on wound circle radius R and diaphragm seal 9 tops, both used a computer and calculated, also to just can reach the appropriate result of apolegamy with a lot of supporting values, so R, the different values with a of e can obtain similarly many spinning roller curves of Fig. 3 and Fig. 4, and can not reach appropriate cooperation, even can't work.By R=49mm, e=7mm, three parameters of a=2mm, by cylinder body and triangular-piston rotor spinning roller curve equation, on the xoy coordinate, the cylinder body that the some point values that calculate by the changing value at θ angle are drawn and the cylinder body cavity surface and the triangle piston profile of triangular-piston rotor spinning roller curve plotting are most preferred embodiments of the present utility model.Detect the correctness of its both spinning roller curve, the ρ 1=116mm shown in available Fig. 2, Fig. 3, ρ 2=88mm, L1=88mm, the physical dimension of L2=37mm is verified and is weighed.

The utility model is specially adapted to 4～10 horsepowers motorcycle rotary engine.
