随车起重机发动机加速现有2种方式。一是脚踏油门式,二是软轴油门式。这2种方式在使用中都有一定的局限性。我们研制的新型发动机转速与起重动作的随动机构采用滚子推杆和盘形凸轮装置,滚子推杆即油门拉杆,而盘形凸轮安装在油门操作手柄一端,通过盘形凸轮与滚子推杆相对位置变化带动油门拉线 Truck crane engine acceleration in two ways. First, pedal throttle, the second is the throttle throttle. These two methods have some limitations in use. We developed a new engine speed and lifting movements follow-up mechanism using the roller and cam disc cam device, the roller lever that is the throttle lever, and the disc-shaped cam mounted on one end of the throttle handle, through the disc cam and roll The relative position of the sub-push rod drives the throttle cable
