附 录A The Design of Pull Arm Garbage Truck 1The introduction of Pull Arm Garbage Truck Pull arm garbage truck is equipped with two types of chassis that has a trunk load and unloading functions to pull arm device-specific vehicles. It can be achieved with car trunk the combination and separation, while the bulk of the trunk to achieve self-unloading cargo operations. The model has been widely used in foreign countries, often in the domestic industry as a sanitation refuse collection vehicles. 5 t pull arm garbage truck is one of the commonly used models, compared to 8 t Arm pull over large tonnage trucks, the pull-arm device structure is relatively simple and easy to domestic Manufacturers; And large tonnage often imported pull arm device. Domestic Manufacturers producing 5 t pull the car pulling the boom arm structure of the device, although about the same, but the important structural parameters o the selection and design o di erent structural arrangement, it will directly a ect the car performance [20] . 2 Pull the boom structure and principle of the device 2.1 The structural characteristics of pull-arm device 5 t pull arm garbage truck pulling device consists of pulling the boom arm and pull arm cylinder, the United Moving frame, trunk insurance hook and cylinder, and the frame. La Boom device structural arrangement shown in figure 2, pull telescopic arm is not used right-angle bend structure. the end of the cylinder and pull the piston rod side arm hinged on the hinge pivot B; Another linkage frame front end and hinged at the hinge pivot C, the formation o a rotary arm pull heart. Cylinder head cylinder arm pull side hinged front frame on the hinge pivot A; linkage frame hinged rear axle frame rear hinge pivot D, the formation o linkage rotary frame heart. Insurance linkage tr
