Without bump-stops, a vehicle that "bottoms out", will experience a very hard shock when the suspension contacts the bottom of the frame or body, which is transferred to the occupants and every connector and weld on the vehicle. Factory vehicles often come with plain rubber "nubs" to absorb the worst of the forces, and insulate the shock.
A common application is in vehicle suspension systems, where a bushing made of rubber (or, more often, synthetic rubber or polyurethane [1]) separates the faces of two metal objects while allowing a certain amount of movement. This movement allows the suspension parts to move freely, for example, when traveling over a large bump, while ...
Hysteresis of structural material, for example the compression of rubber disks, stretching of rubber bands and cords, bending of steel springs, or twisting of torsion bars. Hysteresis is the tendency for otherwise elastic materials to rebound with less force than was required to deform them. Simple vehicles with no separate shock absorbers are ...
The huge haul trucks, which can weigh up to 450 tonnes (440 long tons; 500 short tons), require a much larger wheel chock that itself will weigh almost 40 kilograms (88 pounds). These circumstances will benefit from urethane wheel chocks that are lightweight enough to be maneuvered, yet can withstand the responsibility of holding a truck if a ...
Nose up, tail down attitude of vehicle without self-levelling suspension. Many vehicle systems on a conventional vehicle are negatively affected by the change in attitude coming from changes in load - specifically a heavy load in the rear seat or luggage compartment. [1]
Cut-way of a deflated railway vehicle air spring bellows. 'A' is the rubber bellows element. Air bag or air strut failure is usually caused by wet rust, due to old age, or moisture within the air system that damages it from the inside. Air ride suspension parts may fail because rubber dries out.
