Influence of removable anti-skid device on the soil density

Abstract

The ways to improve the traction characteristics of the wheel MTA by the drive wheels loaders, the use of additional removable loads, the filling of the drive wheels chambers with liquid, the traction force of the tractor due to the increase in the coupling mass are studied. However, with the increase in the structural dimensions of the wheels and the use of dual tires improve the functional properties of the engines, however, significantly increase the cost of the engine, its dimensions, complicated handling of the machine. The use of removable anti-skid devices on the wheel drive increases the vertical load due to the weight of the anti-skid device. At the moment of interaction of the hook with the soil, the force required to introduce it into the soil, reduces the load on the wheel. A formula for determining the density of soils in the Wake of the mover is obtained. Depending on the magnitude of the force of introduction into the soil, two modes of interaction of the wheel with the soil are considered. To improve the traction properties of the engine, a new design of the device support was developed. After the introduction of the support to a dense layer of soil, it is opened, thereby increasing the contact area and sharply reducing the pressure of the wheel drive tires on the upper layers of the soil. Due to this process, the wheel (partially or completely) is not in contact with the topsoil. The equipment of propellers of wheeled vehicles with removable anti-skid devices, which allow to increase traction properties, reduce the compacting effect of the propulsor on the soil, seems to be a rational solution to the problem of increasing the traction characteristics of the driving wheels. The equipment of wheel machines movers with removable anti-skid devices allows to approximate the traction characteristics of wheel machines to the characteristics of crawler type movers due to the interaction of hooks with more compacted layers of the subsurface horizon soil.
