The Exploration and Improvement of Steering Heavy for Heavy Dumper

摘要

The heavy phenomenon about the steering system for 6 x 4 dumpers is presented. Checking computations steering system parameter on theory, it can find out the steering system performance cannot be improved effectively according to the theory parameters. At the same time, the comparative analysis is carried out with the same type of dumpers which are reflected fairly good on the marketplace. The main reason is found out about the steering heavy on the dumpers. It carries out an optimization on the dumper's system parameters. The test results show that the steering performance of the dumpers is improved obviously, and better than the same type of competitor's dumpers. Heavy vehicles is generally used to power steering system at home and abroad, however, in the actual operation process, steering system often appear to heavy phenomenon, especially heavy dump trucks, and because of the severe overloading, steering heavy show particularly outstanding phenomenon. Steering heavy will cause the vehicle steering difficult, add to the driver fatigue, influence the safe driving, reduce automobile driving smooth and stability, and directly affect the driver's personal safety, so it must be ruled out [1].
