Adjustable shock-absorbing leg for motor vehicles

An adjustable shock-absorbing leg (1) for motor vehicles is described whose adjustment requires little expenditure of force. For this purpose, a stop bushing (11) is located unloaded by a spring assembly of the adjustable shock absorbing leg (1) on a damper housing (2b). The spring assembly consists of two helical springs (6, 7) which are connected one behind the other and have a different spring constant and are separated by an annular element (8). Whilst in the case of low loading of the spring assembly the annular body (8) does not come to rest with the stop bushing (11) and therefore the softer, lower helical spring (7) leads to a low spring constant, in the event of the annular element (8) resting against the stop bushing (11), the harder upper helical spring (6) is actuated exclusively. By changing the distance between the annular element (8) and the stop bushing (11) a displacement-dependent and therefore load-dependent change in the spring constant can be achieved. The adjustment ...

SUSPENSION DEVICE

A suspension device is equipped with a damper including a piston portion, a suspension spring, an upper seat, and a spring. The spring is arranged between the piston portion and the upper seat and is an elastic member for receiving a load from the damper. The spring has load characteristics in which hysteresis does not occur, whereby a dynamic spring constant can be small. Therefore, transmission of vibrations in a high-frequency range and an infinitesimal amplitude range is decreased. The spring has a main body that functions as a disc spring portion. Therefore, the spring constant in a direction perpendicular to an axis line of the damper is large, whereby stiffness in the direction perpendicular to the axis line is increased. As a result, ride quality is improved, and stable handling is obtained. 1.
