Description

A kind of wheel tyre explosion safety control device of the unmanned mine car of 4 wheel driven
Technical field:
The utility model belongs to the field of automobile active safety, and a kind of wheel of the specific design unmanned mine car of 4 wheel driven is blown out Safety control, the safety auxiliary control after being blown out for unmanned mine car, it is intended to improve the stability after unmanned mine car is blown out With security and operating efficiency.
Technical background:
According to related data investigation statisticses, the traffic accident 70% on highway is above is because the automobile run at high speed is quick-fried Caused by tire, and driver can cause car crash due to lacking the experience progress faulty operation for emergency processing of blowing out, and follow Automobile can usually knock into the back phenomenon, and automobile of blowing out can also collide with surrounding driving vehicle and cause more serious traffic thing Therefore therefore the control technology blown out it is most important.Prior art is mainly the tire pressure collection by tire air pressure monitoring unit Signal is sent to the central control unit of automobile, and central control unit decision-making simultaneously sends brake hard instruction to establish tyre explosion safety Control system, longitudinal direction execution unit closes air throttle after receiving control instruction during automobile flat tire, and horizontal execution unit receives control Steering assistance motor is controlled to maintain preferable travel direction after instruction.Orthodox car is usually front-wheel steer, in automobile flat tire When, pass through active front steering system (Active front steering, AFS) or the stable electronic system of vehicle body (Electronic Stability Program, ESP) can control the stability for rear vehicle of blowing out to a certain extent, but It is the standard configuration system that ESP system is not automobile, and both control systems are nor being directed to automobile flat tire and designing 's.It is usually the spare wheel carrier beam device of design mine car for the control that mine car is blown out and tire pressure is carried out to the tire of mine car With the monitoring and controlling of temperature, need to configure spare tyre on mine car using the device of spare wheel carrier, and be limited to the shadow of mine car application environment Ring, the diameter of tyres and width of mine car are all larger, so spare tyre carries inconvenience, the application of spare wheel carrier can influence the cloth of vehicle Put;To mine car tire with tire pressure and the monitoring and controlling of temperature, the monitoring system that the method needs needs control algolithm, and The program of complexity is write in entire car controller, it is necessary to using more sensor, under the severe working environment of mine car not Easily ensure the normal operating conditions of monitoring system.Unmanned technology is the focus of colleges and universities and business research in recent years, also by The great attention of country, and the case of existing unmanned vehicle work and preferable application is obtained in the aerospace industry and communications and transportation Effect, therefore unmanned vehicle can be applied to the industrial circles such as mining soon, therefore, this patent design is applied to the quick-fried of unmanned mine car Tire safety control has preferable application value.Some shortcomings in the prior art be present:First, traditional control of blowing out is more It is to provide a kind of control method, it is necessary to write the control program of complexity in entire car controller, and it is auxiliary based on a kind of safety is designed Help the scheme of device few;Second, the control device of blowing out of design is mostly to be based on hydraulic system, Hydraulic Elements manufacture and processing essence Degree requires higher, and assembling is relatively difficult, valve system and oil circuit is more, fluid by temperature and whether there is air it is mixed have a great influence, oil System reliability is influenceed after liquid pollution, arrangement is inconvenient, and failure is not easy to check and excluded;Third, do not examined fully after automobile flat tire Consider tire and take off the danger that rim is further brought;Fourth, do not account for blow out after load distribution inequality problem.
This patent devises a kind of wheel tyre explosion safety control device of the unmanned mine car of 4 wheel driven, passes through the electricity in drive mechanism Machine provides power for leverage transmission mechanism, and leverage transmission mechanism realizes the connection of connection articulated structure to realize by be hinged structure The change of leverage relative position, it is simple and reliable for structure, be easy to fabricate;Kinematic pair is face contact, and pressure is small during work, carrying Ability is big, impact resistance;In the case where the driving link characteristics of motion is constant, driven member is made by the relative length for changing each component The different characteristics of motion is obtained, is easily controlled the characteristics of motion of mechanism;When safety aid moves to final state, output transmission Bar can be contacted and rolled with road surface perpendicular to ground, auxiliary wheel, and the vertical active force between auxiliary wheel and ground makes quick-fried Axletree where tire wheel highly raises two wheel lifts so that on axletree, and four-wheel automobile switchs to three-wheel driving mode, avoids four The danger that wheel rim comes off occurs for the coaxial wheel of not blowing out of wheel automobile flat tire wheel, avoids unmanned mine car when higher speed travels The hidden danger of trailing wheel elder generation locking occurs after blowing out because of brake hard;Auxiliary wheel is equipped with hub driven motor, is driven by wheel hub Motor reversal provides partial brake power for automobile of blowing out, two wheels automobile caused by liftoff of axletree where making up wheel of blowing out The decrement of brake force, the unmanned mine car for making to blow out are capable of the parking of safety or worked on after gradual slow down, avoid There is the generation of the accidents such as sideslip, whipping or overturning;The fork configuration of auxiliary wheel is connected with being designed with the defeated of shock absorber structure Go out drive link connection, auxiliary wheel can be relaxed and contacted to earth caused impact, and make traveling process of the unmanned mine car after blowing out Middle buffering, damping, improve the ride comfort of running car.
