Problems solved by technology

There are some shortcomings in the prior art: the one, traditional tire blowout control is mostly to provide a kind of control method, needs to write complicated control program in the whole vehicle controller, and the scheme based on designing a kind of safety auxiliary device is seldom; Most of the designed tire burst control devices are based on the hydraulic system. The manufacturing and processing precision of the hydraulic components is high, and the assembly is relatively difficult. There are many valve systems and oil circuits. The system reliability will be affected after the liquid pollution, the layout is inconvenient, and the faults are not easy to check and eliminate; the third is that the further danger of the tire rim is not fully considered after the car blows out; the fourth is that the uneven distribution of the load after the blowout is not considered

Abstract

The invention discloses a tire burst safety guaranteeing auxiliary device applicable to a four-driven unmanned mine truck, and aims to improve the safety of the unmanned mine truck after tire burst of a wheel and ensure the working efficiency of the mine truck. The auxiliary device consists of a driving mechanism, a transmission mechanism, a connecting structure and an auxiliary wheel, wherein the driving mechanism adopts an auxiliary motor as a power source of the safety guaranteeing auxiliary device; the transmission mechanism adopts a rod system, and comprises a plurality of transmission rods working together; the connecting structure adopts a hinged structure, and is used for fixing the safety guaranteeing auxiliary device and connecting the mechanisms; the auxiliary wheel is equipped with a wheel hub driving motor, is mounted on a fork-shaped mechanism, and provides a part of a braking force for the unmanned mine truck after the tire burst. The tire burst safety guaranteeing auxiliary device has the characteristics of convenience in mounting and dismounting, convenience in maintenance, suitability for working in a harsh working condition and the like; during working, the tire burst safety guaranteeing auxiliary device has a self-locking function so as to improve the working reliability thereof.

Description

[0001] Technical field: [0002] The invention belongs to the field of active safety of automobiles, and specifically designs a tire blowout safety auxiliary device suitable for four-wheel drive unmanned mining vehicles, which is used for safety auxiliary control of unmanned mining vehicles after tire blowouts, and aims to improve the safety of unmanned mining vehicles. Stability and safety and work efficiency after a flat tire. [0003] technical background: [0004] According to relevant data survey statistics, more than 70% of traffic accidents on the expressway are caused by high-speed automobile tire blowouts, and drivers who lack experience in emergency handling of tire blowouts will cause car crashes and fatalities if the driver makes a wrong operation. There will be a rear-end collision, and the car with a flat tire will collide with the surrounding vehicles to cause more serious traffic accidents. Therefore, the control technology of the flat tire is very important. T...
