Problems solved by technology

The shroud is mostly used for trucks, and its structural features are not suitable for passenger cars; the drainage roof is mostly used for hatchback passenger cars, and its drag reduction effect is far from optimal because it only guides the top airflow

Embodiment Construction

[0024] Embodiment 1 of the vehicle of the present invention, as Figure 1-4 As shown: the vehicle includes a compartment 1, and the tail of the compartment 1 is provided with a drainage frame, and the drainage frame includes a drainage top plate 2 and a drainage side panel 3. The drainage side panels 3 are arranged on the left and right sides of the drainage top panel 2 . The drainage side panel 3 can be used in commercial vehicles, including trucks and passenger cars.

[0025] The drainage roof 2 is fixedly connected to the upper edge of the rear of the compartment 1, and the two are fixedly connected by rivets. In other embodiments, the two can also be fixedly connected by welding. The drainage top plate 2 extends left and right. The length and thickness of the drainage roof and the angle between the drainage roof and the compartment are optimized by computational fluid dynamics. In other embodiments, the drainage top plate may also be omitted.

Abstract

The invention relates to a carriage tail drainage side plate, a drainage frame and a vehicle. The vehicle comprises a carriage, wherein a drainage side plate is arranged on the side edge on the tail part of the carriage, and the drainage side plate is hinged with the carriage. By adopting the carriage tail drainage side plate, the drainage frame and the vehicle, the air resistance when the vehicle runs at a high speed can be effectively reduced, and the energy conservation and emission reduction can be realized.

Description

technical field [0001] The invention relates to a drainage side plate, a drainage frame and a vehicle at the tail of a carriage. Background technique [0002] Energy saving and emission reduction technology is one of the main directions of commercial vehicle research today. Reducing the fuel consumption of commercial vehicles can not only reduce the cost of use, but also alleviate environmental problems such as smog and acid rain, which has significant social and economic benefits. [0003] Commercial vehicles need to overcome acceleration resistance, climbing resistance, rolling resistance and air resistance when driving. Existing experimental studies have shown that when the vehicle speed exceeds 70km / h, the resistance of the air to the body becomes an important factor affecting the fuel economy, maximum speed and handling stability of commercial vehicles. At the same time, air resistance is proportional to the square of the vehicle speed, and it will increase sharply wi...
