Swinging arm type truck second modification pollution

prevention

Abstract

City life rubbish in transit, whether cause secondary pollution, necessary and shipment of rubbish are directly related to vehicle design structure. Such as loaded compressed type after the truck and other sealing structure can prevent rubbish endlessly picturequre scene in transit; And currently in use of swing arm garbage trucks, easy cause secondary pollution, therefore we according to the structure of swing arm modify the truck.

Vehicle modified design

The original car design for completely open wide type, hoisting rubbish bucket without any block structure, cabin garbage in transit endlessly picturequre scene easily. Modification scheme in the car compartment front-end department and left-right side each additional fixed windshield wallboard, adding activity type in top guide enclosures wind. The top area of about 2/3 the size of the guide enclosures wind, left-right side each small oil cylinders, open or closed guide enclosures wind. Front windscreen wallboard can stop the level and on the right direction of wind and streamlined guide enclosures wind is able to have a top vertical wind guide up and effectively solved the problem of the car endlessly picturequre scene rubbish.

Guide enclosures wind and truck of swing arm mechanical motion relationship Swinging arm type truck is to rely on the swing arm before and after exercise to ascend garbage box and realize the since installed or dump. So modified design new portfolio of top mobile guide enclosures wind, fluctuation open or closed with the swing arm swinging must be between corresponding coordination, namely the mechanical motion is according to operation requirements through hydraulic system for sequence control.

Vehicle load transport conditions

Hydraulic system three spool reversing valve valve core is the central position, swinging arm, inlet cover working condition at rest.

Vehicle dump garbage conditions

Directional control valves, pulled to the right in that right valve spool central position. In

hydraulic system under the effect of sequence control oil, first through

Guide enclosures wind small oil cylinder full open the inlet cover, then make main cylinder push to swing arm swinging, ascending car after dumping garbage dou compartments discharge box. Or fight .

Vehicle outfit garbage conditions

The working conditions of the directional control valve valve core right is pushed into a central location, through hydraulic system sequence control oil make swinging arm and conducting enclosures wind mechanical motion and the aforementioned dump contrary, namely first working back swinging arm, outfit garbage dou compartments, then close ventilation hood. So far, the garbage dump vehicle from the pack complete homework. Modification of vehicle performance after the influence of modified vehicle, its structure, weight after would affect the performance of vehicles? It needs from the following two major aspects of verification.

Vehicles a force sex and economy

The budget of the windshield, adapted before adding area approximately 3 m2, the panels that vehicle air resistance FX increases, the formula

Knowable vehicle resistance increased by 1 7.6 ~ 2 840 N, namely 180 ~ 2.9 kg. In addition in the original car windshield wallboard and add by adding

Weighing about 370 kg. Two total 550 ~ 660 kg, namely for increased vehicle maximum additional load. But this loose living garbage for maximum load with vehicles 3.5 ~ 4.0 t terms still not overload (rated load 5 t), its engine power, economy still in normal use range. Vehicle safety and handling

Because modified vehicle integral structure still is symmetric, former rear-axle lotus distribution within the normal range. Therefore adapted for vehicles to, not the security of the system and manipulation of brake performance produce any adverse effects.
