    摘要： A stabilizer bar for controlling the roll of an automotive vehicle has left and right sections, each provided with a torsion rod and a torque arm. The torsion rods are aligned along a transverse axis and attached to a structural component of the vehicle, while the torque arms are connected to the left and right control arms of the vehicle's suspension system. In addition, the bar has a coupling between the torsion rods of the two sections for controlling the torsional stiffness of the bar. The coupling includes a rotor fitted to one of the torsion rods and a housing fitted to the other torsion rod, with the housing receiving the rotor, such that a cavities exist between the rotor and housing. Both the rotor and housing carry vanes, that alternate so that the vanes of the rotor are located between the vanes of the housing. The cavities contain a magneto-rheological fluid. The bar also includes an electrical coil controls the viscosity of the fluid either at the coupling or at a valve located remote from the coupling, but in either place, such that the variations in the viscosity of the fluid control the torsional stiffness of the stabilizer bar.

    摘要： An automotive vehicle has road wheels that are coupled to suspension uprights of the vehicle through wheel ends that have the capacity to monitor lateral loads that act on the road wheels at tire patches where the road wheels contact a road surface. Each wheel end offsets displacements that would be produced within the wheel end by vertical loads with displacements that would be produced by moments induced by the vertical loads, so that the remaining displacements within the wheel end reflect essentially lateral loads exerted at the tire patch. The wheel end contains a sensor and a target that the sensor monitors to detect the presence and magnitude of the displacements and hence the magnitude and direction of the lateral force at the tire patch. The sensor may also monitor angular velocity, angular position, and temperature.

    摘要： A clutch (A,B) includes a cam (20,70) and a rotor (22,74), both of which revolve around a common axis (X). The cam has a camming surface (30,72) provided with lobes (32), whereas the rotor carries pistons (26,80) which bear against the camming surface of the cam. The pistons project from piston cavities (40,42; 76) in the rotor and those cavities communicate through a connecting cavity (44,78), to thereby form a fluid chamber (56,82) of constant volume which contains a magneto-rheological fluid (28,84). An electrical coil controls the viscosity of the rheological fluid. When the viscosity is low, the pistons will move inwardly and outwardly on the rotor as the camming surface passes over them and no torque will transfer between the cam and rotor. However, when the fluid is viscous, the fluid will impede displacement of the pistons in the piston cavities, and the pistons will grip the camming surface sufficiently to enable torque to transfer between the cam and rotor.

    摘要翻译： 离合器（A，B）包括凸轮（20,70）和转子（22,74），两者都围绕公共轴线（X）旋转。 凸轮具有设置有凸角（32）的凸轮表面（30,72），而转子承载抵靠凸轮的凸轮表面的活塞（26,80）。 活塞从转子中的活塞腔（40,42; 76）突出，并且这些空腔通过连接空腔（44,78）连通，从而形成恒定体积的流体室（56,82），其包含磁流变学 流体（28,84）。 电线圈控制流变液的粘度。 当粘度低时，当凸轮表面越过它们时，活塞将在转子上向内和向外移动，并且转矩将不会在凸轮和转子之间传递。 然而，当流体是粘性的时，流体将阻止活塞在活塞空腔中的位移，并且活塞将充分地夹紧凸轮表面，以使转矩能够在凸轮和转子之间传递。
