Abstract:
A rolling reducing apparatus for a vehicle, comprising:suspension means for absorbing shock generated by driving the vehicle and for supporting a vehicle chassis, said suspension means comprising a lower arm connecting the vehicle chassis to a wheel carrier, and a link assembly for detecting a decrease in a distance between the lower arm and the vehicle chassis;centrifugal force compensating means for detecting centrifugal force generated by turning the vehicle and compensating for the centrifugal force by increasing the distance between the vehicle chassis and the lower arm beyond the decrease in the distance detected by the link assembly;wherein said suspension means further comprises an air spring, disposed between the vehicle chassis and the lower arm, for supporting the vehicle chassis, a compressed air source for compressing air, and a leveling valve for selectively supplying air compressed by the air source to the air spring to cause the increase in the distance between the lower arm and the vehicle chassis; andwherein said centrifugal force compensating means comprises a crank member assembly disposed between the link assembly and the leveling valve, said crank member assembly comprising a crank body, a weight fly attached to a lower portion of the crank body, a first eccentric protrusion formed on one side of an upper portion of the crank body, said first eccentric protrusion being pivotably connected to the link assembly, and a second eccentric protrusion formed on the other side of the upper portion of the crank body, the second eccentric protrusion located below the first eccentric protrusion and pivotably connected to the leveling valve, wherein said crank member controls the leveling valve to supply air compressed by the air source to the air spring by a pivot motion of the weight fly.
