Modern Automotive Wheel Alignment Technology Research And Discussion

In the last few years, fly to develop soon along with economic developments in our country, the mobile car in our country retention measures to too pass to increase over 10% speed annually, is an inside particularly, the upscale car increases speed also astonishing. Modern all of car manufactory house, all have been aware of the vehicle passes by to drive a period of time empress, driving the department automotive with change direction the department the inside the each movable spare parts, willing result in to drive the stability automotive because wear away, change direction the easy and convenient with embark the comfortable etc. function all descent having obviously. For example: Reduce to shake the spring coil flexibility tired, the chassis is apart from the ground lowers highly. Automotive a wear and tear for and changing direction system a movable spare parts, will cause the spare parts loosen to move, the phenomenon that crossbeam flections or carriages tilt to one side. Above all situations, all will result in the vehicle the driver the minor faults on the function, and the fuel consumes excessive, the spare parts accelerates ground wear away, the tire wears away play etc. phenomenon. For the sake of wear and tear that lower the spare parts, car manufactory with idea car bedrock strut and change direction the system give the betterment, making its can proceed the adjustment within the scope of certain, satisfy to give the in expiation of function because of the spare parts wears away.The abroad adjusts to the car four- wheeler fixed position the technical research there has been many year, but our country batch quantity produce car only contain 120 years, our country of car produce basic up is to usher in the foreign technique with production line, for example the Volkswagen Santana, Jatta, golf etc. all belong to family use the car, at foreign country already many years in gave birth to. The four-wheeler of for this reason these caress type positions and adjusts, or usher in the ex- technique condition. Current these caresses are already basic to eliminate abroad, returning in the country at produce. So improve to the four-wheeler fixed position adjustment technique of these caress type, can in the car manufactory and society together, all gives to put into practice to the new old car.The investigative work in this text is divided into primarily three part: The first, pass the analysis before in to the car proceed four- wheeler fixed position examination process an instrument for using equipments with examine the method, find out its existent key problem; The second, the local four- wheeler positions the technical present condition now, aiming at some four- Wheelers fixed position parameter of the some familiar car type (familiar strut a construction) can't proceed the project that regulatory present condition put forward solution, and verify the possibility of the project; The third, for increases to manipulate and stabilize the function automotive, to in common use McPherson strut in car with control up and down the arm strut the excellent turning afresh. Should many dynamics analyze the method, establishing the McPherson strut with control up and down many dynamics of the arm strut a system analysis model, make use of that model to proceed to the ex- a fixed position parameter in car the improvement designs, and proceeded the improvement the design to the McPherson strut according to the excellent parameter turning behind.
