具有弹簧和倾转基座的扭转减震装置
摘要：
一种扭转减震装置，包括：两个同轴元件(12)，其安装成抵抗弹簧(8)作用能相对于彼此转动；及用于弹簧定位的两个基座(4、6)。每个基座(4、6)包括背面枢转凸起(14)，其可在设于两个同轴元件中的两个槽座内枢转。背面枢转凸起(14)通过圆柱部分界定，圆柱部分具有第一圆弧(15)，在第一圆弧的外端部处的切线与弹簧的轴线形成角度α。每个槽座的截面由第二圆弧(16)形成，第二圆弧的中心和曲率半径与第一圆弧(15)的中心和曲率半径相同，在第二圆弧的外端部处的切线与弹簧的轴线形成大于角度α的角度γ。枢转轴线以间距L彼此平行，包含在位于与转动轴线距离R处的平面中。装置最大游隙角度为δ。γ属于区间[arctg(L/2R)-δ/8，arctg(L/2R)+δ]。
摘要（英）：

This device comprises two coaxial elements (12) mounted rotating relative to each other, against a spring (8), and two seats (4, 6) for positioning the spring. Each seat (4, 6) comprises a pivoting dorsal protrusion (14) that can pivot in two housings provided in the two coaxial elements. The pivoting protrusion (14) is delimited by a cylinder portion, having a first circular arc section (15) of which the tangent at the outer end of this arc forms an angle a with the axis of the spring. The section of each housing is formed by a second circular arc (16), having the same centre and radius of curvature as the first circular arc (15), of which the tangent at the outer end forms an angle gamma greater than alpha with the axis of the spring. The pivot axes are parallel at a distance L from each other, and are included in a plane positioned at a distance R from the axis of rotation. The maximum clearance angle of the device is delta. Gamma belongs to the interval: [arctg(L/2R) - delta/8, arctg(L/2R) + delta].
