Abstract:

For the purpose of studying loading of automobile transmission, the paper dwells on the road-experimental research program on the 4X4-type automobile with 5-ton carrying capacity, which envisages the testing of vehicle on the asphaltic, cobblestone and dirt roads, at different values of tire internal pressure. In accordance with values of radial rigidities determined under bench-test conditions, therehas been established the impact of their changes on torque moment, and conditions of choosing the optimal values of tire rigidity and damping radial axis for the different-type roads.

Keywords: smooth ride, tire, spring, carrying capacity, dynamic characteristics
