Embodiment Construction

[0024] In the different figures, similar components are in each case assigned the same reference numerals, and therefore said components are only described once as a whole.

[0025] figure 1 Shown is a perspective side view of a portion of a prior art steering column 1 . The steering column section shown comprises a torque transmitting shaft 2 connected at its axial ends to respective conventional prior art universal joints 3 and 4 . exist figure 1 The steering column section described in is used in a manner known per se to be used by the steering wheel ( figure 1 not shown) is transmitted to a steering mechanism (also not shown), for example a rack and pinion steering mechanism.

[0026] For this purpose, the steering wheel is via, for example, an additional axis ( figure 1 not shown) is connected to the figure 1 The joint yoke 5 of the upper universal joint 3 is shown, and the input side of the steering mechanism is connected to figure 1 The joint yoke 5 of the lower u...

Abstract

The invention relates to a universal joint for connecting torque transmission shafts (2, 11) with two pitch yokes (6, 16), each of which can be connected to the shaft (2, 16) , 11) one of which each of the shafts defines a shaft longitudinal axis (10, 12) and each pitch yoke (6, 16) carries a pair of bearing means (7), each of the bearing means defining joint axes (8, 9), the universal joint has a joint part (13) arranged between the joint yokes (6, 16) with two complementary pairs of bearing means ( 14), wherein the two pitch yokes (6, 16) are coupled to each other by means of the joint part (13) in such a way as to involve a pairwise interaction between the bearing arrangement (7) and the complementary bearing arrangement (14) . At least one joint axis (8, 9) encloses an acute or obtuse angle (α, β) with the respective shaft longitudinal axis (10, 12). The invention further relates to a steering column of a motor vehicle equipped with at least one such universal joint.

Description

technical field [0001] The invention relates to a universal joint for connecting a torque transmission shaft of a motor vehicle, in particular a steering column, and a steering column adapted thereto. Background technique [0002] The steering column in a motor vehicle transmits the steering angle and the steering torque from the steering wheel to a steering mechanism, for example a rack and pinion steering mechanism, in a manner known per se. Steering columns that are commonly used today have joints on the transmission path, in particular universal joints or Hooker joints, in order to allow, for example, even an offset path of the steering column connection. In this way, a shorter steering column section can be achieved, and thus better positioning from an accident point of view, and an adjustment to spatial conditions can likewise be achieved. However, the steering transmission ratio of the steering column is in this case generally a periodic function of the steering whee...
