    摘要: A vehicle is supported by wheel and tire assemblies. The assemblies each have a tire mounted around a cylindrical wheel rim and retained in place by an annular retaining ring that abuts the wheel rim and the tire. A lock ring is located in an annular groove in the wheel rim and abuts the retaining ring to hold the retaining ring in place against the tire. A tension plate is connected to the retaining ring through a set of tap screws to hold the tension plate against the end of the wheel rim and thereby retain the annular ring and the tire against rotation around the rim.

    摘要: A selectable multi-wheel drive system for a mining machine has an electrical motor directly driving a wheel and driving a hydraulic pump through a clutching mechanism. Another wheel is connected to be driven by a hydraulic motor connected through a hydraulic circuit to be driven by the hydraulic pump. The hydraulic pump is selectively connected to the hydraulic motor so that one wheel or both wheels may be driven. The hydraulic circuit is controlled so that when in a one wheel drive condition the hydraulic motor is placed in a free-wheeling mode and no losses occur in the hydraulic circuit because of connection to the wheel.
