Embodiment Construction

[0015] As shown in Figure 1 and 2.

[0016] The light-weight optimization and dynamic balance optimization technology of the present invention designs a CG150 engine for a motorcycle, including a piston ring 6, a piston ring 7, an oil ring 8, a piston 9, a piston pin 10, a crank connecting rod assembly 5, and a piston pin gear clip 11 , cylinder 12, left box body 1 and right box body 2 etc. parts. Its working principle is the same as internal combustion engine technology.

[0017] Its improved structure involves the following parts: the first piston ring 6 and the second piston ring 7 are reduced by 1 / 3 compared with normal; the thickness of oil ring is reduced by 2 / 5 compared with normal; the total height of piston is reduced by 1 / 3 compared with normal piston , the skirt is also opened to increase three oil storage tanks 16; the length of the piston pin 10 matched with the piston is reduced by 4.4mm compared with the normal, and the outer diameter of the piston pin is reduc...

Abstract

The invention relates to a CG150 engine adopting light-weight optimization and balance optimization technology, belonging to the motorcycle engine field. It mainly solves problems that the whole machine has serious vibration and outputs of power and torque are smaller because the rotational inertia is not appropriate and friction loss is larger. The optimization design not only relates to thermal parts such as piston, piston ring, piston pin, piston block joint and cylinder so on but also changes main parts such as crank-connecting rod, box, crank bearing, bearing pushing bolt and variable speed assembly so on. By decreasing frictional loss of thermal parts outputs of power and torque are improved. By optimal dynamical balance rate and main shaft angle the vibration is decreased. By changing transmission ratio the effect of comfortable riding is obtained. It is used for motorcycle engine so as to be suitable for mountain road.

Description

technical field [0001] The invention relates to the technical field of motorcycle engines, in particular to a CG150 engine for motorcycles (including tricycles) using lightweight optimization and dynamic balance optimization technologies. Background technique [0002] At present, the CG150 engine widely sold in the market is a mature model, but in actual use, there are generally serious vibrations of the whole machine and power and torque output caused by large running inertia and large friction loss. Minor problems cannot meet the requirements of customers, especially those using in mountainous road conditions. Since the structure and related parameters of this type of engine are fixed, it is difficult to try to overcome the above-mentioned problems by changing the local structure, because for a mature model, it is often "moving the whole body". Contents of the invention [0003] The invention provides a CG150 engine for motorcycles designed with light-weight optimizatio...
