Abstract
The invention provides a resistance-reducing connecting cover body arranged between a truck head and a carriage of a container freight truck, which relates to a connecting cover body arranged between the truck head and the carriage of the container freight truck. The invention solves the problem that a flow guiding cover arranged above a cab of the container freight truck only can be used for reducing a positive pressure zone generated by the positive impaction of airflows, but can not be used for reducing a negative pressure zone generated by air flow and resistance caused by the impaction of the airflows. A portal cover body comprises a first vertical plate, a second vertical plate and an upper transverse plate, wherein the thickness of the first vertical plate, the second vertical plate and the upper transverse plate is 8mm; the first vertical plate, the second vertical plate and the upper transverse plate are inclined to the direction of an inner cavity of the portal cover body and have equal inclination angles; the first vertical plate and the second vertical plate are made of flexible materials, and the portal cover body is removably connected with the end surface of the front end of a container and the end surface of the rear end of the cab. The invention is used for the resistance-reducing connection between the truck head and the carriage of the container freight truck.

The containerized shipment truck is behind loading container, there is very big space between headstock operator's compartment and the freight container, according to aerodynamic principle, the containerized shipment truck in the process of moving, because the motion of gas, produce strong turbulent flow in the gap between operator's compartment and freight container, cause energy dissipation, form the resistance that zone of negative pressure and gas shock freight container outshot cause.Existing containerized shipment truck is installed streamlined reefer housing for addressing the above problem above operator's compartment, streamlined reefer housing only can reduce the zone of positive pressure that the air-flow frontal impact produces, and can not reduce the zone of negative pressure of air flows generation and the resistance that gas shock causes.
Summary of the invention
The objective of the invention is only can reduce the zone of positive pressure that the air-flow frontal impact produces for solving the existing streamlined reefer housing that is installed in containerized shipment truck cap top, and can not reduce the problem of the resistance that zone of negative pressure that air flows produces and gas shock cause, provide a kind of containerized shipment truck headstock that is installed in to be connected cover body with drag reduction between the compartment.
The present invention includes upper cross plate, the starting stave and second riser, the starting stave and second riser are symmetricly set on the two ends of upper cross plate, and the starting stave and second riser and upper cross plate constitute gantry shape cover body, starting stave, the thickness of second riser and upper cross plate equates, its thickness is 5mm-10mm, starting stave, second riser and upper cross plate all tilt to the interior cavity direction of gantry shape cover body, and starting stave, the angle of inclination of second riser and upper cross plate equates, its angle of inclination is 50 °～80 °, upper cross plate, the material of the starting stave and second riser is flexible material, the large end face of gantry shape cover body reclines mutually with the front end end face of freight container, and the front end end face of gantry shape cover body and freight container removably connects, the small end face of gantry shape cover body reclines mutually with the rear end end face of operator's compartment, and the rear end end face of gantry shape cover body and operator's compartment removably connects.
The present invention has the following advantages: one, shape cover body employing flexible material in gantry of the present invention, and gantry shape cover body is with headstock operator's compartment and freight container smooth connection, form the osed top outward appearance, both can eliminate the zone of negative pressure that air flows produces, can reduce the resistance that gas shock causes again, reach the purpose of drag-reduction energy-saving.Two, gantry shape cover body of the present invention and operator's compartment and freight container removably connect, and easy and simple to handle.
Description of drawings
Fig. 1 is an integral structure front view of the present invention, Fig. 2 is the A-A cutaway view of Fig. 1, Fig. 3 is the B-B cutaway view of Fig. 1, and Fig. 4 is that the large end face of gantry shape cover body 6 is connected with freight container 5, the small end face of gantry shape cover body 6 and operator's compartment 4 bonded assembly running condition figure, and Fig. 5 is the birds-eye view of Fig. 4.
