摘要： The present invention relates to a method of controlling a variable damper in a vehicle wherein a rear-wheel variable damper can be controlled by estimating a vertical acceleration value of a rear wheel based on the fact that there is a certain time delay in a wheel motion between front and rear wheels due to the wheelbase and vehicle speed. To this end, the method of the present invention comprises the steps of (a) detecting vehicle body accelerations other than a desired vehicle body acceleration of a vehicle body; (b) calculating the desired vehicle body acceleration based on the other detected vehicle body accelerations according to a geometric rule; (c) calculating vehicle body vertical velocities by filtering the vehicle body accelerations to eliminate DC offsets therefrom and integrating the filtered accelerations; (d) detecting accelerations of front right/left vehicle wheels; (e) calculating front wheel vertical velocities by filtering the detected accelerations of the front right/left wheels to eliminate DC offsets therefrom and integrating the filtered accelerations, and then calculating accelerations of rear wheels by time delaying the accelerations of the front wheels by a time interval taken while a road input to the front wheel is delivered to the rear wheel at a vehicle speed; and (f) calculating damper velocities based on the calculated vehicle body vertical velocities and the calculated vehicle wheel vertical velocities. Accordingly, the Sky-hook determination can be more accurately made. Further, since it is not necessary to use all the four sensors, the number of parts of vehicles can be reduced when mass-producing the vehicles. Consequently, the selling prices for finished vehicles can be lowered, and thus, an unnecessary economical burden cannot be imposed on the consumers.
摘要翻译：本发明涉及一种控制车辆中的可变阻尼器的方法，其中可以通过基于在车轮运动中存在一定时间延迟的事实来估计后轮的垂直加速度值来控制后轮可变阻尼器由于轴距和车速而在前后轮之间。为此，本发明的方法包括以下步骤：（a）检测除了车体的期望的车身加速度以外的车身加速度; （b）根据几何规则，基于其他检测到的车身加速度来计算所需车身加速度; （c）通过过滤车体加速度来计算车体垂直速度以消除其中的直流偏移并积分经滤波的加速度; （d）检测前右/左车轮的加速度; （e）通过对所检测到的前右/右轮的加速度进行滤波来计算前轮垂直速度，以消除其中的直流偏移并对滤波的加速度进行积分，然后通过将前轮的加速度延迟一段时间来计算后轮的加速度输入前轮的道路以车速输送到后轮时所经过的间隔; 和（f）基于计算的车身垂直速度和计算的车轮垂直速度计算阻尼器速度。因此，可以更准确地进行天钩确定。此外，由于不需要使用所有四个传感器，因此在批量生产车辆时可以减少车辆的部件数量。因此，可以降低成品车的销售价格，不能对消费者造成不必要的经济负担。

摘要： Axle-chassis connecting device is particularly for a commercial vehicle having two tandem axles of the hydropneumatic suspension type. The vertical load coming from the chassis is transmitted directly to the wheels by jacks (23) without passing through the axle tanks, and is taken into account near the wheel plane by means of a multifunction part (20) which further assures, simultaneously, the connection of the axle to the chassis by a longitudinal guide rod (26) and the transmission of the braking torques coming from the braking means (35).

摘要： An air spring apparatus for a vehicle suspension. An active air cylinder and piston of the apparatus are connected in series with the vehicle suspension. An inactive air cylinder constituting an air column extension of the active air cylinder is connected in series with the active air cylinder by an air conduit. The spring rate of the system is automatically adjustable to produce optimum isolation of impulsive forces and to maintain the forces on the road under dynamic conditions essentially equal to those forces under static conditions.
