四冲程内燃机发动机通常包括气缸、 曲柄连扞机构、 曲轴飞轮组 和配气机构。在发动机的工作过程中, 燃料和空气以一定的比例通过 进气门进入气虹, 经压缩后点火燃烧变为热能, 燃烧后的气体所产生 的高温高压, 作用于活塞顶部, 推动活塞直接运动。 连杆连接活塞和 曲轴,把活塞的直线运动转化为曲轴的旋转运动, 并通过曲轴来直接 分配发动机产生的动力。 曲轴一端设置飞轮,把动力传递到离合器上 驱动车辆运动。 曲轴的另一端设置曲轴定时齿轮, 通过皮带或者链条 与凸轮轴上的凸轮轴齿轮相连,控制气门的开启和关闭。但是无论是 采用皮带或者链条传动, 都有其不足之处。链条在传动过程中和与其 相啮合齿轮不断摩擦, 容易产生磨损, 使得动力分配发生变化, 偏离 原来设定的分配比例。 如采用皮带传动, 则要求皮带具有足够的宽度 以传输需要的力矩, 这就会增大发动机组的宽度,使得安装了该发动 机组的机动车, 特别是摩托车的车身显得更加笨重。 发明内容  A four-stroke internal combustion engine typically includes a cylinder, a crank linkage mechanism, a crankshaft flywheel assembly, and a valve train. During the working process of the engine, the fuel and air enter the gas rainbow through the intake valve at a certain ratio. After compression, the ignition combustion becomes heat energy, and the high temperature and high pressure generated by the burned gas acts on the top of the piston to push the piston directly. . The connecting rod connects the piston and the crankshaft, converts the linear motion of the piston into the rotational motion of the crankshaft, and directly distributes the power generated by the engine through the crankshaft. A flywheel is arranged at one end of the crankshaft to transmit power to the clutch to drive the vehicle to move. The crankshaft timing gear is disposed at the other end of the crankshaft, and is connected to the camshaft gear on the camshaft by a belt or a chain to control the opening and closing of the valve. However, whether it is a belt or a chain drive, there are deficiencies. The chain is constantly rubbed during the transmission and meshing with the gears, which tends to cause wear and tear, which causes the power distribution to change, deviating from the originally set distribution ratio. If a belt drive is used, the belt is required to have a sufficient width to transmit the required torque, which increases the width of the engine block, making the vehicle in which the engine unit is mounted, particularly the body of the motorcycle, more cumbersome.
