    • A vibration damping mount capable of reducing vibration and noise, and improving vehicle stability and controllability. Between an inner cylindrical sleeve and outer cylindrical sleeve which are coaxially arranged with each other, a vibration-damping rubber body is disposed and joined thereto. A stopper plate is secured to a lower end of the inner cylindrical sleeve. The vibration-damping rubber body extends from the lower end thereof along a flange which projects outward from a lower end of the outer cylindrical sleeve to define an annular rubber stopper. An end edge of the annular rubber stopper abuts a peripheral part of the stopper plate. A rubber spacer is disposed in an annular space defined by the rubber stopper, vibration-damping rubber body and stopper plate so as to be compressed and generate a reaction force upon obliquely applied loads due to the relative displacement between the inner sleeve and outer sleeve, thereby reducing vibration and noise with friction damping, and improving vehicle stability and controllability against the obliquely applied loads by applying an increased spring constant upwardly.
    • 一种能够减轻振动和噪音,提高车辆稳定性和可控性的减振支架。 在彼此同轴布置的内圆柱形套筒和外圆筒形套筒之间,设置并连接减振橡胶体。 止动板固定在内圆柱套筒的下端。 减震橡胶体从其下端沿着从外圆柱形套筒的下端向外突出的凸缘延伸以限定环形橡胶塞。 环形橡胶止动件的端缘与止动板的周边部分抵接。 橡胶垫片设置在由橡胶塞,减振橡胶体和止挡板限定的环形空间中,以便由于内套筒和外套筒之间的相对位移而被倾斜施加的载荷上产生反作用力, 从而通过向上施加增加的弹簧常数来减少具有摩擦阻尼的振动和噪声,以及改善车辆稳定性和针对倾斜施加的载荷的可控性。

    • A hydraulic damping device for preventing the transmission of vibrations of wide-ranging frequencies. The device includes a thick vibration damping rubber body which defines a main liquid chamber therewithin, first and second deformable rubber diaphragms which respectively define first and second auxiliary liquid chambers, first and second passageways for respectively connecting the auxiliary liquid chambers to the main liquid chamber, each passageway generating liquid resonance in a predetermined frequency vibration range different from each other, and a bottom plate for defining a pressure chamber with the first deformable rubber diaphragm which defines the first auxiliary liquid chamber connected with the main liquid chamber by the first passageway generating liquid resonance in a high-frequency vibration range. The pressure chamber is selectively brought into communication with the atmosphere or a negative pressure source. When idle vibrations are input, the pressure chamber communicates with the atmosphere to freely deform the first deformable rubber diaphragm, whereby a damping liquid flows mainly through the first passageway and accordingly the idle vibrations are effectively absorbed, whereas when shake vibrations are input, the pressure chamber communicates with the negative pressure source to restrict the free deformation of the first deformable rubber diaphragm, whereby the damping liquid flows mainly through the second passageway generating liquid resonance in a low-frequency vibration range, and accordingly shake vibrations are effectively restrained.
    • 一种用于防止大范围频率的振动传播的液压阻尼装置。 该装置包括在其中限定主液室的厚度减振橡胶体,分别限定第一和第二辅助液室的第一和第二可变形橡胶隔膜,用于将辅助液室分别连接到主液室的第一和第二通道, 每个通道以预定的频率振动范围彼此不同地产生液体共振;以及底板,用于限定具有第一可变形橡胶膜的压力室,该第一可变形橡胶膜限定通过第一通道产生液体与主液室连接的第一辅助液室 谐振在高频振动范围内。 压力室选择性地与大气或负压源连通。 当输入怠速振动时,压力室与大气连通以使第一可变形橡胶隔膜自由变形,由此阻尼液主要流过第一通道,因此怠速振动被有效地吸收,而当输入振动时,压力 室与负压源连通以限制第一可变形橡胶隔膜的自由变形,由此阻尼液主要流过在低频振动范围内产生液体共振的第二通道,从而有效地抑制了振动。
