Automobile wind-resistance brake device and electrical control system thereof

Abstract

Disclosed are an automobile wind-resistance brake device and an electrical control system thereof. An approximate-square groove is formed in an automobile body plate. A horizontal movable turning plate which can outwardly open a certain angle to serve as a choke plate is mounted in the groove. The opening angle of the movable turning plate is determined by a group of tensioning devices. Opening of the movable turning plate is achieved by a group of electromagnetic opening-closing mechanisms. Closing of the movable turning plate is achieved by self weight, pull force of the tensioning devices and suction force of the electromagnetic opening-closing mechanisms. Locking of the movable turning plate is achieved by a group of electromagnetic locks. A plurality of raised gratings are formed on the inner side of the movable turning plate to increase resistance of the movable turning plate. By the brake device, wind resistance coefficient of an automobile is variable, the wind resistance coefficient is small during normal travelling of the automobile while the wind resistance coefficient becomes quite large during emergency brake, and accordingly an automobile brake system is helped to reduce brake distance greatly.

Description

technical field [0001] The invention relates to an auxiliary braking system of an automobile, in particular to a wind resistance braking device and its electrical control system. Background technique [0002] Wind resistance is an important factor affecting the speed of a car. For a long time, people have regarded wind resistance as an unfavorable factor, and have worked hard to study how to reduce the wind resistance coefficient of a car, so as to increase the speed of the car and reduce the overall energy consumption of the car. However, wind resistance also has a positive side. When a car running at high speed is performing emergency braking, people hope to use wind resistance for auxiliary braking, thereby reducing the speed of the car and shortening the braking distance of the car to the greatest extent. Chinese patents No. 03241621.0 and No. 201220009259.9 disclose two kinds of wind resistance braking devices. But the shortcoming of No. 03241621.0 patent technical sc...

AI Technical Summary

Problems solved by technology

But the shortcoming of No. 03241621.0 patent technical scheme is that the matching operating mechanism of its cable is difficult to be configured in the existing automobile, and the structure of the choke plate is bulky and bulky, and it is not easy to be installed on the automobile; On the roof of the train, hydraulic cylinders and hydraulic pump station systems are used to control the take-off and landing of the choke plate, and a large fairing is also required. This solution is also not suitable for use in automobiles.
