Heavy-duty truck pneumatic brake device based on wireless remote control

Abstract

The invention provides a heavy-duty truck pneumatic brake device based on wireless remote control, which comprises a brake air path, a brake mechanical device and a wireless remote control device based on radio frequency. The brake air path is connected with the brake mechanical device. The wireless remote control device based on radio frequency drives the brake mechanical device through the brake air path to realize the wireless remote control braking of a heavy-duty truck. A special pneumatic line is arranged, a pneumatic valve is controlled through an electromagnetic valve, a manual braking mechanism is simulated and the instant accurate braking of the heavy-duty truck is realized. The heavy-duty truck pneumatic brake device based on wireless remote control has the characteristics of simple structure, high stability and reliability, low cost and the like; since the wireless remote control device based on radio frequency adopts a high-reliability radio-frequency chip, the long-distance remote control braking is realized; and since an electrically-controlled air brake system and the original foot brake system are mutually independent and do not interfere with each other, a manual brake and an electric brake form an 'OR' relationship and the reliability of emergency braking is greatly improved.

Description

technical field [0001] The invention relates to high-reliability emergency braking of heavy trucks and monitoring of the Internet of Things, in particular to a pneumatic brake device for heavy trucks based on wireless remote control. Background technique [0002] In today's society, with the development of science and technology, in the fields of industrial production and national defense construction, the movement, handling and installation of large-scale structures are becoming more and more frequent. Large-scale transportation equipment has been developed abroad for many years. With the development of contemporary industrial technology, especially driven by hydraulic transmission and electronic control information technology, the field of large-scale equipment road transportation vehicles has developed rapidly, and the technology has gradually matured. [0003] With the development of information technology, especially the wide application of the Internet of Things, peopl...

AI Technical Summary

Problems solved by technology

[0003] With the development of information technology, especially the wide application of the Internet of Things, people have a comprehensive understanding of the relevant information in the operation of heavy trucks, but the control technology hinders the lack of high-reliability actuators, so the motor is out of joint, and it is impossible to control the heavy trucks. exercise effective control

[0004] Under normal circumstances, heavy-duty trucks are bulky (nearly 20m long, 3m wide, and nearly 3m high), weigh tens of tons, and the driver's control distance from the rear is nearly 20m. Due to inertia, the operator of a conventional mechanical device Difficult to brake precisely
