Embodiment Construction

[0022] The figure shows a joint yoke 10 and a rod 11 which together form a connecting device 13 made up of the joint 10 and the rod 11 .

[0023] The universal joint fork 10 comprises a fork-shaped base 14 which has two legs 15 extending parallel thereto and which are connected at the end opposite the fork-shaped base 14 to a transverse beam 16 . In the fork base 14 there is provided a recess 17 which extends centrally through the fork base 14 .

[0024] In the recess 17, which is also referred to as a through-hole, through-hole or through-opening, a toothing is provided, said toothing at Figure 4 shown in . exist figure 2 The teeth are shown in . The toothing is formed in the form of a thread 18 , so that the toothing in the recess 17 is an internal thread.

[0025] The thread 18 thus has a continuous helical turn which passes through the substantially cylindrical wall of the recess in the form of an incision. At least the bulge that rises relative to the notch forms t...

Abstract

The invention relates to a connection device consisting of a yoke (10) and a rod (11), wherein the yoke has in a recess (17) teeth running transversely to the longitudinal axis and the rod (11) has a longitudinal Teeth. Furthermore, the invention relates to a method for producing such a connecting device.

Description

technical field [0001] The invention relates to a connection device of a cardan shaft having two parts engaging with each other. Furthermore, the invention relates to a method for producing a lever-fork connection. Background technique [0002] Cardan shafts are primarily used in situations where a compliant clutch is no longer sufficient to transmit torque if the axes of rotation are misaligned or if parts move relative to each other. Cardan shafts are also used for length compensation. [0003] The gimbal shaft includes at least one yoke joint connected to a rod or shaft. For torque transmission, in such connections, also known as shaft-hub connections, the contact or connection surfaces of the two components are usually connected to one another in a force-fit and / or friction-fit manner. For this purpose, the contact surfaces are provided with knurls (teething) which ensure a good force fit or friction fit. [0004] The connecting surface of the joint yoke which is arr...
