Abstract
A kind of boss wheel stroke piston combustion engine can be widely used on car, lorry, aircraft, steamer and the tank.Form by cylinder head, cylinder block, cam shell etc., it is characterized in that there is a cylindrical cam that links by spline and main shaft the cylinder block back.Have the enclosed shape arc groove that connects to form with the semi-circle symmetry on the boss wheel outer peripheral surface, and link by ball and piston rod.When the piston drivening rod is reciprocating, promotes boss crop rotation circumference and rotatablely move.
Description
The invention belongs to boss wheel stroke piston combustion engine.
At present, stroke piston combustion engine has obtained using widely.But, because main movement parts is a connecting rod, just there is complex structure, it is big to overcome inertial force, the irregular weighing apparatus of moment of torsion, volume is big, and power/liter little is manufactured deficiencies such as difficulty.
The disclosed F0 4 B85100359 crankshaft circular slide block reciprocating piston internal combustion engines of Chinese patent, have simple in structure, the characteristics that volume is little.But, because this machine cylinder adopts and vertically passes through layout mutually, when the cylinder number increased, volume obviously increased, simultaneously, because this machine is by crank block, bent axle and a pair of internal gear pair change the to-and-fro motion of piston into and rotatablely move, and have the structure relative complex, the processing and assembling difficulty, the manufacture cost height, the deficiency that friction factor is big, the power of motor and moment of torsion also are subjected to certain limitation.
In order to address the above problem, the invention provides a kind of compact structure, boss wheel stroke piston combustion engine in light weight, that volume is little, power performance and economic performance are good.This machine does not have bent axle and crankcase, substitutes bent axle with boss wheel, one week of main axis rotation, but twice of each cylinder work done.Therefore, compare with similar conventional machine, power/liter and moment of torsion can improve about 4 times, volume and weight can reduce 50%-60%, 85% component can be general with conventional uniform machines.It is little to have the inertial force of overcoming, cheap for manufacturing cost, and running is steadily lubricated characteristic of simple.Can be widely used on car, lorry, aircraft, steamer, the tank.

The present invention is achieved in that in the back of cylinder block 2 cylindrical cam 4 that links by spline 7 and main shaft 8, has with the semi-circle symmetry on the boss wheel outer peripheral surface to connect the encapsulation arc groove of forming 9, and links by ball 10 and connecting rod 6.When piston 5 drivening rods are reciprocating, promote boss crop rotation circumference and rotatablely move output power.
Be described in detail below in conjunction with accompanying drawing.
Boss wheel reciprocating IC engine is mainly by cylinder head 1, and cylinder block 2, cam shell 3, boss are taken turns 4 compositions such as grade.Cylinder head, cylinder block, cam shell, boss wheel, piston, connecting rod arrange in the same way along main shaft 8, and cylinder 11 arranges along main shaft cylindrical contour, and general one week of main axis rotation, each cylinder can work done 2 times.
Cylinder head 1 is arranged at main shaft 8 front portions.The front links by sliding bearing 12 and main shaft, and the back links by bolt and cylinder block 2.Cylinder head is provided with suction tude 13, outlet pipe 14, valve seat, timing cam 15, camshaft 16, camb cap 17, spark plug 18, bathtub shape firing chamber 19.Valve, valve seat is arranged along spindle parallel; Overhead camshaft is arranged along the main shaft warp-wise; Each cylinder is provided with a short camshaft and two cams, and is fixed on the cylinder head by rolling bearing 20, is sealed by camb cap.Cone gear 22 engagements that camshaft links by the coaxial cone gear that links 21 with main shaft, its rotating ratio is 2: 1.
Cylinder block 2 is arranged at main shaft 8 middle parts.Back and cam shell 3 link, and the cylinder block transverse section is rounded.Two 11 in adjacent cylinders have cooling water chamber 23.If employing wind, oil mixes cooling, and the cylinder wall periphery can be provided with some radiating fin.The cylinder block axle center links by a pair of thrust cylindrical bearing and main shaft.
Connecting rod 6 is inverted T-shape, and front end links by wrist pin and piston 5, and upper rear end is real to be gone out part and place in the guiding groove of connecting rod rack 24, and connecting rod rack is ∩ shape, and by screw on the inner peripheral surface of cam shell 3.The effect of connecting rod rack mainly is to prevent that connecting rod left and right sides in to-and-fro motion is shimmy.Have half spherical recess 25 at the rear end of connecting rod lower surface, a smooth ball 10 is put in the inside, and links by ball and boss wheel.
Boss wheel 4 is near cylinder block 2 rear portions, and the axle center links by spline 7 and main shaft 8.Its width and stroke of piston are apart from equal quantities, and boss wheel maximum radius and cylinder center equate to the distance of spindle axis.On the outer peripheral surface of boss wheel, have with the level and smooth enclosed shape half-arc groove 9 that connects of semicircle camber line symmetry, the radius R of circular arc equals half of stroke of piston, and the radius of the radius of arc groove and ball 10 equates.When the piston drivening rod is reciprocating, promote the boss wheel by ball, and the drive main shaft rotatablely moves as circumference together.Boss wheel sense of rotation and connecting rod vibration-direction are perpendicular.Connecting rod is every finishes air-breathing, compression, expansion, four strokes of exhaust through four circular arc cylinders, and makes merit one time.Generally speaking, on the boss wheel eight circular arcs that link can be set.Under the certain situation of boss wheel radius, cylinder can be taken turns cylindrical contour maximum limit amount along boss and be arranged.
Embodiment: one four cylinder boss wheel reciprocating IC engine, cylinder diameter 92mm, stroke of piston 92mm, 2.445 liters of swept volumes, compression ratio 6.6: 1,230 horsepowers of peak outputs (3000 rev/mins), motor maximum diameter 45CM, extreme length 65CM.
Behind the alternative bent axle of boss wheel, complete machine is arranged compact more along main axis.The processing of boss wheel is easy, with low cost, and simultaneously, the inertial force of reciprocating motion of the pistons is almost all taken turns wheel shaft to passing to main shaft along boss, makes engine running more steady, helps reducing oil consumption.Simultaneously, the component of timing cam, valve, piston etc. 85% can be general with conventional uniform machines, further reduced the complete machine manufacture cost.
