Abstract

The utility model relates to a CG150 engine applying the optimization and balancing optimization techniques, belonging to the field of the engine for motorcycle or tricycle. The utility model mainly solves the problems that the whole machine vibrates seriously and the torque output is very small due to inappropriate moment of inertia and great friction loss. The optimal design relates to a plurality of thermal parts: piston, piston ring, piston pin, piston block and other parts. Besides, the utility model correspondingly improves the design of crank linkage, housing, crank axle, bearing pin, transmission assembly and other main parts to reduce the friction loss of the thermal parts; then the power and the torque output are thus improved; the balancing rate and the drift angle of the main shaft are optimized to reduce the vibration; the transmission ratio is changed. The utility model has the advantages that people feel comfortable when driving and the utility model can be applied for the motorcycle or tricycle to drive in mountainous areas.

Technical field

The utility model relates to motorcycle engine technical field, particularly applying lightweight optimization and dynamic balance optimization technique motorcycle (containing tricycle) CG150 motor.

Background technique

At present, the motor of the CG150 model of widely selling on the market is a kind of type of maturation, but in actual use, ubiquity seriously reaches power, moment of torsion output problem of smaller because of running inertia reaches the big complete machine oscillation that causes of frictional loss more greatly, can not satisfy particularly mountain area road conditions use requirement of client of client.Because its structure of motor and the relevant parameter of this kind model are fixed, attempt that to overcome the problems referred to above be difficult by changing partial structurtes, because, often " pull one hair and move the whole body " for the type of a maturation.

The model utility content

The utility model provides the motorcycle CG150 motor of a kind of moving element applying lightweight optimization and dynamic balance optimization technique design, and the complete machine oscillation that it can solve the prior art existence seriously reaches power, moment of torsion output problem of smaller.

The technical solution of the utility model is: the CG150 motor of applying lightweight optimization and dynamic balance optimization technique, comprise piston one ring, piston two rings, oil ring, piston, wrist pin, crank rod assembly and wrist pin shelves card, cylinder, left box body and right case, it is characterized in that piston one ring and piston two rings more all reduce 1/3; Oil ring thickness more normally reduces 2/5; The piston height overall reduces 1/3 more normally, and compares with normal piston, and the skirt section has oil storage tank; The wrist pin length that matches with piston more normally reduces 4.4mm, and piston pin external diameter more normally reduces the weight of 2mm piston one ring, piston two rings, oil ring, piston all than normally alleviating 1/3; The more normal short 0.55mm of cylinder height dimension; The weight of crank rod assembly more normally alleviates 1/3; Left box body and right case crankshaft bearing aperture more normally enlarge 4mm to cooperate with reinforcement absorbing left side crankshaft bearing, right crankshaft bearing respectively.

Further technological scheme is:

Piston one ring thickness is 0.8mm; Piston two ring thicknesses are 0.8mm; Oil ring thickness is 1.5mm; Piston height overall 40.2mm, and there are three road oil storage tanks in the skirt section; Wrist pin aperture φ 13mm, piston pin external diameter are φ 13mm.

The crank rod assembly weight that comprises left crankshaft bearing, right crankshaft bearing and timing gear is the 3200-3220 gram; The connecting rod small end aperture is φ 13mm, and the major part aperture is φ 36mm.

The external diameter of left side crankshaft bearing (3) and right crankshaft bearing (4) is φ 72mm, reaches corresponding left box body (1) and right case (2) crankshaft bearing aperture and is φ 72mm.

The beneficial effects of the utility model are:

Because of the frictional loss of piston ring group and piston plays a leading role, it also is the major obstacle that restriction internal-combustion engine mechanical efficiency further improves, so in the utility model, fully take into account piston ring sealing, running-in ability, scrape under the suitable prerequisite of oiliness, burnish resistance, antifriction quality and face pressing, one, two ring thicknesses are more normally reduced 1/3, oil ring thickness more normally reduces 2/5, reaches the purpose of the loss of reducing friction; Guaranteeing that piston safety is durable and resisting under the prerequisite of serious heat load and mechanical load, depth pistion is more normally reduced 1/3, about weight saving 1/3, increase by three road oil storage tanks simultaneously in the skirt section, to reach the purpose of the loss of reducing friction, rotating speed reinforcement and raising performance; The crank-connecting rod combination takes light-weight design, weight more normally to alleviate about 1/3, reduces the amount of unbalance of crank-connecting rod operation process, to reach the purpose that alleviates complete machine oscillation; Use the reinforced left and right sides crankshaft bearing that possesses shock sucking function, further alleviate the uneven vibration that causes of crank combination running.

The utility model makes it can produce the effect that power, moment of torsion output increase and complete machine oscillation reduce because of frictional loss that has reduced the heating power parts and lightweight optimization and the dynamic balance optimization that has realized main running gear.
