Abstract

[0002] With the continuous development of automobiles and special sanitation vehicles, it is found that the power output transmission assembly of the sanitation vehicle engine and the cylinder that drives the power output transmission assembly are installed at different positions on the vehicle, one is installed on the engine and the other is installed on the vehicle frame.
[0003] Since the engine is installed in a soft connection manner (fixed by a soft rubber shock pad), while the cylinder fixing bracket is in a hard connection manner (welded to the vehicle frame), this causes the engine to vibrate during operation, and the power output transmission assembly and the cylinder fixing bracket cannot vibrate at the same frequency. When the vehicle is running, the separation fork shaft and arm assembly of the engine power output transmission assembly and the cylinder piston rod generate eccentric angles, resulting in collision and overloading, which will damage parts such as the cylinder, Y-joint and separation fork arm. After a period of use, the engine shock pad will deform, with a deviation from the position adjusted before leaving the factory, which further exacerbates the wear and damage of the cylinder, cylinder joint and cylinder fork arm, causing the special vehicle to be unable to operate normally.
