Results of studies of the influence of a wheeled propeller on the parameters of a high-pass vehicle in winter conditions
One of the main problems in the transportation of agricultural goods by road in conditions of snow drifts and deep snow is a decrease in traction and coupling properties and the collapse of vehicles with the formation of a deep track. These factors lead to an increase in the force of resistance to movement and, as a consequence, to an increase in the amount of slipping. At present, multipurpose KamAZ vehicles are widely used for the transportation of goods in winter snowy conditions, especially for agricultural purposes. In conditions of low bearing capacity of the soil, in icy conditions or in the presence of high snow cover, these cars cannot fully realize their traction and coupling properties due to the high specific load on the propeller with a relatively small contact patch. It becomes necessary to reduce the normal pressure of the wheel propellers on the soil, which is possible due to the installation of arched tires with a large support area. The article presents experimental studies of the KamAZ-43501 car on arched tires.
