摘要： A tripod type constant velocity universal joint for interconnecting two shafts to permit transmission of a driving force in a vehicle such as a motor car. In said tripod type constant velocity universal joint, a trunnion portion of the tripod shafts is urged against and supported by a tulip portion of a second shaft by a tripod spring, the spherical head of a mushroom-shaped member provided in the mounting hole of said trunnion portion is kept in contact with a recess in said tulip portion by the biasing force of a compression spring, and further, said mushroom-shaped member or said trunnion portion of the tripod shafts is formed to provide a spherically curved surface or a conical surface incorporating a straight line, in which the distance from the center of the joint is increased as a point on the external configuration leaves the center toward the outer periphery.

摘要： An arm direction changeover valve (11) is provided in an arm block (20). A first pilot check valve (18) is provided in a first block (21). A second pilot check valve (19) is provided in a second block (22). The three blocks, i.e., the arm block (20), the first block (21), and the second block (22) are arranged side by side. The first block (21) and the second block (22) are arranged to be contiguous to each other. Accordingly, an increase in size can be prevented even if a float mechanism and a multi-direction changeover valve are formed integrally with each other.

摘要： A bellows-form boot for universal joint which is formed integrally of a le-diameter cylindrical portion and a small-diameter cylindrical portion at both ends, the former being adapted to be fitted to a joint case housing therein the universal joint and the latter to a driving shaft, a central annular bellows portion having ridge portions whose diameters are tapered down toward the small-diameter portion, and a bracing boss portion extending between the large-diameter portion and the bellows portion. The boss portion has a wall thickness of 2 to 3 times the average wall thickness of the bellows portion and is profiled so that the inner face thereof may abuttingly contact with the edge face of the joint case and the outer face thereof is flush with the outer face of the bellows portion in the mutual joining area. The bellows portion has, at its zone adjacent to the boss portion extending from the end to the crest of the first ridge portion thereof, wall thicknesses gradually increasing from the latter to the former, whose maximum is a half the wall thickness of the boss portion.

摘要： A dust boot for a universal joint covering two joint elements having largely curved corner portions in the outer peripheral surface thereof near their joint portion, comprises a resilient annular covering portion for covering the joint portion of the universal joint and two annular end portions which are integrally formed with the covering portion in axially both ends thereof. The annular end portions are mounted on the two joint elements near their joint portion. Since the area of an open end of the dust boot mounted on the joint element having largely curved corner portions is made smaller than the cross sectional area of the outer peripheral surface of the joint element, specifically only the curvature of the open end of the dust boot corresponding to the largely curved corner portions of the joint element is made smaller than that of the corner portions of the joint element, the dust boot can be closely mounted on the joint element with excellent sealing effect.
摘要翻译： 一种用于万向接头的防尘罩，其覆盖在其接合部分的外周表面处具有大的弯曲角部的两个接头元件，包括用于覆盖万向接头的接合部分的弹性环形覆盖部分和一体的两个环形端部 在其两端形成有覆盖部分。 环形端部在其接合部分附近安装在两个接头元件上。 由于安装在具有大的弯曲角部的关节元件上的防尘罩的开口端的面积小于接头元件的外周面的截面面积，具体地仅仅是灰尘的开口端的曲率 与接头元件的大部分弯曲的角部相对应的靴子被制成小于接头元件的角部的靴子，防尘罩可以以良好的密封效果紧密地安装在接头元件上。
