A novel energy-saving truck air guide cover

Abstract

The invention discloses a novel energy-saving truck air guide cover, comprising a mounting bottom plate and a flow guide cover body mounted on the top of the mounting bottom plate. The mounting bottomplate is provided with transverse reinforcing ribs, and the transverse reinforcing ribs are welded to connect the vertical reinforcing ribs; the transverse reinforcing ribs are welded to the verticalreinforcing ribs. One end of the mounting bottom plate is arc-shaped, and the arc-shaped end of the mounting bottom plate is connected with the flow guide cover body through a hinge; A main body of that air guide cover is an arc plate, and the side wall of the main body of the air guiding cover is provided with an air guiding groove; At that other end of the air deflector cover body, an adjustinglever is mount, and the other end of the adjusting lever is connected and mount on the top of the mounting bottom plate. The invention has simple structure and reasonable design. A slotted groove isarranged on the top of the air guide cover body to prevent the air flow from forming a negative pressure region at the rear of the air guide cover body and reduce the pressure difference resistance caused by the air flow separation. The device adopts a streamline structure as a whole. At the same time, the wind power on the main body of the air guide cover can be effectively decomposed through theair guide groove, which reduces the resistance of the vehicle and the fuel consumption of the vehicle, and is suitable for promotion and use.

Description

technical field [0001] The invention relates to the technical field of vehicle wind deflectors, in particular to a novel energy-saving truck wind deflector. Background technique [0002] As we all know, the box body of a van is higher than the cab, and there is a height difference and a certain gap, which makes the shape of the vehicle discontinuous and the streamline poor. When the van is running at high speed, when the airflow above the cab hits the upper part of the front part of the closed compartment, a large peeling will occur from the front edge of the compartment roof, and the value of the air resistance coefficient will increase accordingly. If a flow guiding device is installed on the top cover of the cab to make a streamlined transition between the cab and the compartment, so as to guide the airflow flowing through the upper part of the cab to "connect" with the upper surface of the compartment, so that the airflow can flow along the roof of the closed compartment...

Problems solved by technology

[0003] However, at present, the shape of the existing wind deflector is mainly arc plate. Although this kind of wind deflector is easy to process and has a certain drag reduction effect, it cannot improve the external flow of the truck to the greatest extent, and it is easy to cause damage to the wind deflector. A large negative pressure area is formed at the rear edge of the cowl, which is not conducive to the driving of trucks; at the same time, the air guide method of the existing air guide is integral, which cannot decompose the wind force applied to the air guide. High resistance, affecting fuel consumption
