    • The invention relates to an adjustable camshaft (1) for the valve train of an internal combustion engine, having an outer shaft (10) and an inner shaft (11) extending concentrically with the outer shaft (10) and rotatably accommodated therein, wherein on the outer surface (13) of the outer shaft (10), at least one cam member (12) is rotatably mounted while forming a slide bearing gap, wherein the cam member (12) is connected to the inner shaft (11) in a rotationally fixedly manner. According to the invention, in the outer surface (13) of the outer shaft (10), at least one oil routing groove (14) is introduced in a position and with an axial length such that the oil routing groove (14) is formed at least across the axial width of the slide bearing gap, and that on at least one side of the cam member (12), the oil routing groove is brought out from the slide bearing gap with a free groove portion (15).
    • 本发明涉及一种用于内燃机的气门机构的可调节凸轮轴(1),具有外轴(10)和与外轴(10)同心地延伸并可旋转地容纳在其中的内轴(11),其中, 在所述外轴(10)的外表面(13)上,至少一个凸轮构件(12)可旋转地安装,同时形成滑动轴承间隙,其中所述凸轮构件(12)与所述内轴(11) 旋转固定地。 根据本发明,在外轴(10)的外表面(13)中,至少一个导油沟槽(14)被引入到具有轴向长度的位置中,从而形成导油沟槽(14) 至少横跨滑动轴承间隙的轴向宽度,并且在凸轮构件(12)的至少一侧上,油路由槽从滑动轴承间隙带出自由槽部(15)。

    • The invention relates to a camshaft, especially for motor vehicle engines, comprising a first shaft and a second shaft forming a hollow outer shaft (1) and an inner shaft (2) arranged coaxially in the outer shaft (1) and mounted in such a way that it can rotate in relation to the outer shaft (1). Said camshaft also comprises first cams (3a) arranged on the outer shaft (1) in a rotationally fixed manner, and second cams (3b) that are arranged on the outer shaft (1) and fixed to the inner shaft (2). According to the invention, the first shaft and the second shaft are supported against each other in the axial direction (x) by means of a formfitting shape (5), the first shaft, seen in the axial direction (x), comprising a first contact surface (6a) on one side of the formfitting shape (5) and a second contact surface (6b) on the other side of the formfitting shape (5), for supporting the second shaft in a rotationally movable manner by means of the formfitting shape (5).
    • 本发明涉及一种特别用于机动车辆发动机的凸轮轴,该凸轮轴包括形成中空外轴(1)的第一轴和第二轴以及同轴地布置在外轴(1)中并且以这样的方式安装的内轴(2) 它可以相对于外轴(1)旋转。 所述凸轮轴还包括抗扭地布置在外轴(1)上的第一凸轮(3a)以及布置在外轴(1)上并固定到内轴(2)的第二凸轮(3b)。 根据本发明,第一轴和第二轴通过形状配合形状(5)在轴向方向(x)上相互支撑,从轴向方向(x)看,第一轴包括第一轴 在形状配合形状(5)的一侧上的接触表面(6a)和在形状配合形状(5)的另一侧上的第二接触表面(6b),用于借助形状配合以可旋转运动的方式支撑第二轴 形状(5)。
