    • PURPOSE:To prevent a vehicle from inertially swinging back, in a vehicle attitude control device for restraining the nose-down and squat attitudes of the vehicle, by temporarily hightening the damping force and spring constant of a front or rear wheel suspension system upon the nose-down or squat attitude being detect. CONSTITUTION:When a brake switch and accelerator switch 15 are turned on, a rotary solenoid 13 is deenergized to open an oil passage in a hydraulic damper 1. However, when for example, the switch 15 is turned on, a control circuit 14 operates so that a rotary solenoid 13 is energized to close the oil passage in the hydraulic damper 1 for hightening the damping force of the damper 1. With this arrangement, upon braking the front wheels are controlled but upon accelerating the rear wheel are controlled. Upon the completion of the operation the switch is turned off to deenergize the solenid 13 for returning the control device to its original position. With this construction, the swinging back of the vehicle due to the inertia of the vehicle body may be prevented.
    • 目的:为了防止车辆惯性地摆动,在车辆姿态控制装置中,通过暂时地将前轮或后轮悬架系统的阻尼力和弹簧常数临时提升到鼻子上,以限制车辆的下降和蹲下的姿态 正在检测或下蹲姿势。 构成:当制动开关和加速器开关15接通时,旋转螺线管13被断电以打开液压阻尼器1中的油路。然而,例如当开关15接通时,控制电路14操作 旋转螺线管13被通电以关闭液压阻尼器1中的油通道,以加强阻尼器1的阻尼力。通过这种布置,在制动时控制前轮,但是在加速后控制后轮。 操作完成后,开关关闭,使得控制装置返回原来位置的溶剂13断电。 利用这种结构,可以防止车体由于车体的惯性而摆动。

    • A vehicle suspension system for a trailer (2) comprises a plurality of suspension units (7). Under the normal operating condition of the suspension system, air is supplied from a source (8) to the suspension units by way of level sensing valves (16 and 18). In accordance with the invention, manually operative control means (20, 30) is provided to override operation of the suspension units (7) by the sensing valve (16 and 18), and to permit manual supply of air to and venting of air from the suspension units (7), to enable the height of the vehicle to be manually adjusted. Means is provided to ensure that the suspension system is returned to its automatic operating condition as a result of the vehicle being driven. In the first embodiment this is afforded by a valve (20) which is switched when the braking system of the vehicle is actuated: in the second embodiment the valve (22) is switched by an electrical signal, which may be obtained from the vehicle tachograph, or from actuation of the vehicle braking light, whilst in the third embodiment the suspension system is returned to its automatic mode in consequence of the unplugging of the manually operative control means (38b) from an inlet socket (34b).
    • 拖车(2)的车辆悬架系统包括多个悬挂单元(7)。 在悬挂系统的正常运行状态下,通过液位传感阀(16和18)将空气从一个源(8)供应到悬挂单元。 根据本发明,提供手动操作控制装置(20,30)以通过传感阀(16和18)来超越悬挂单元(7)的操作,并且允许手动供应空气和从空气排出空气 悬挂单元(7),以便能够手动调节车辆的高度。 提供装置以确保悬架系统由于车辆被驱动而返回到其自动操作状态。 在第一实施例中,这是由当车辆的制动系统被致动时切换的阀门(20)提供的:在第二实施例中,阀门(22)由电信号切换,该电信号可以从车辆行驶开关 或者来自车辆制动灯的致动,而在第三实施例中,悬挂系统由于手动操作控制装置(38b)从入口插座(34b)的拔出而返回到其自动模式。

    • The invention provides a vehicle suspension control system comprising means for determining forces acting between the sprung mass (body) of a vehicle and one or more unsprung masses (wheel and hub assemblies) connected thereto and producing signals proportional to the forces, means for resolving the force signals to represent steady state and dynamic force components respectively, first means for determining from the steady state force signals values of vector quantities required between the sprung mass and the or each unsprung mass to maintain a constant orientation of the sprung mass relative to a reference plane, second means for determining, from the dynamic force signals, values of vector quantities required between the sprung mass and the or each unsprung mass substantially to eliminate the transmission of dynamic forces between the sprung mass and the or each unsprung mass and also means for applying the required vector quantities. The invention relates to a control system which analyses the forces experienced by a vehicle suspension system in two categories, dynamic forces and steady state forces. The dynamic forces experienced by the vehicle are those occasioned by road inputs and the steady state forces experienced by the vehicle are those occasioned by vehicle motion.
