Title: Wheel load control device
Inventor: KASAHARA TAMIYOSHI
IPC: B60G17/015
Filed: 1991-11-14
Abstract: PURPOSE:To provide a wheel load control device capable of preventing generation of opposite roll at low speed turning and also increasing turn-round performance of a vehicle more than a conventional suspension device. CONSTITUTION:At the beginning of vehicle turning, since a damping force of damping force variable shock absorbers 11, 12, 13, and 14 is lowered in turning rightward, reduction in a right front wheel load is reduced and the total wheel load on the front wheel side is increased temporarily. As a result, since a cornering force generated on the front wheel side becomes larger than that on the rear wheel side, turn-round performance of the vehicle at the beginning of turning can be increased. Also generation of opposite roll at low speed turning can be prevented.
