The invention discloses a transmission mechanism for adjusting gears of a gear shifting system of a motorcycle engine, one end of the transmission mechanism is connected with a gear shifting foot crank, the other end of the transmission mechanism is connected with a drum shaft, a gear shifting cam coaxially rotating with the drum shaft is arranged at the front end of the drum shaft, and the transmission mechanism comprises a gas spring pull rod arranged outside a crankcase. The two ends of the air spring pull rod are fixedly connected with the gear shifting foot crutch and the gear shifting rod installation block respectively, the gear shifting rod installation block is meshed with the front end of the gear shifting rod assembly, and the rear end of the gear shifting rod assembly is arranged in the crankcase and provided with a shifting rod for shifting the gear shifting cam to rotate. The problems that in the prior art, due to the fact that the overall span of a gear shifting mechanism is long, a plurality of supporting bearings, large return springs and small return springs need to be arranged in the middle, position deviation is prone to occurring, the speed change jamming or slipping fault is caused, and meanwhile the later maintenance difficulty is increased are solved.

    本发明公开了一种调节摩托车发动机变档系统档位的传动机构,该传动机构一端连接变档脚拐,另一端连接鼓轮轴,鼓轮轴前端设有与其同轴转动的变档凸轮,所述传动机构包括设置在曲轴箱外部的气弹簧拉杆,气弹簧拉杆两端分别与变档脚拐、变档杆安装块固定连接,变档杆安装块与变档杆组件前端啮合,变档杆组件后端设置在曲轴箱内部,并设有拨动变档凸轮转动的拨杆。本发明解决了现有技术中变档机构的整体跨度较长,需要在中间设置多个支撑轴承以及大、小回位弹簧,导致容易出现位置偏差,引起变速卡死或打滑的故障,同时也会增加后期的维护难度的问题。
