Abstract: A skid steer vehicle having a set of right driving wheels and a set of left driving wheels, a right driving unit for driving the right driving wheels, a left driving unit for driving the left driving wheels, and a pitching control system to suppress a pitching motion of the vehicle, the pitching control system being provided with a pitching motion detector or detectors to generate a signal indicating occurrence of the pitching motion of the vehicle, and a control unit for individually controlling the right and left driving units until suppression of the pitching motion of the vehicle is detected.

Abstract: A low-vibration steering device for use on industrial vehicles comprising a steering shaft rotatably supported at its lower end by a gearbox and connected to a steering wheel at its upper end, a tubular steering column enclosing the steering shaft with an annular spacing left between the inside diameter of the steering column and the outside diameter of the steering shaft, a steering column clamp secured to a chassis frame of the vehicle and holding the steering column at a portion above its middle portion, a flexible vibration shutoff member disposed between a lower end portion of the steering column and a portion of the steering shaft near its lower end to support the said lower end portion by said portion near said lower end, and an oil-impregnated bearing interposed between an upper end portion of the steering column and a corresponding upper end portion of the steering shaft and having a greater rigidity than the flexible member.
