Means to reduce oscillatory deflection of vehicle
This patent describes a vehicle movable across terrain (T). The vehicle is comprised of a first mass including a vehicle chassis; resilient support means including terrain-engaging wheel assemblies connected to the chassis and enabling reciprocable vertical and angular deflection of the chassis relative to the terrain (T) as the vehicle moves thereacross; a second mass including a load-handling boom component carried by the chassis and independently movable relative to the resilient support means, the first mass being greater than the second mass; means for movably connecting the load-handling boom component to the chassis and enabling reciprocable vertical angular deflection of the component relative to the chassis as the vehicle moves across the terrain (T); and deflection reduction means connected between the chassis and the load-handling boom component to reduce vertical and angular deflection of the chassis relative to the terrain (T) tending to occur in response to dynamic loads imposed on the vehicle by movement across uneven terrain (T) or by acceleration or deceleration of the vehicle; the deflection reduction means including resiliently compressible and expandable load-bearing spring means connected between the chassis and the load-handling boom component and responsive to and tending to enable limited vertical angular deflection of the load-handling boom component relative to the chassis which would cause spring motion at a predetermined rate of speed in response to the dynamic loads, and the deflection reduction means further comprising damping means connected between the chassis and the load-handling boom component and to the spring means to reduce the rate of speed of spring motion as rapidly as possible to thereby dissipate the dynamic loads.
