The invention relates to a steering handle for motor vehicles with the side of one on one Steering column arranged handlebar protruding extensions, on each of which a handle is arranged, wherein the handles are pivotably mounted on the handlebar and are dependent on the rotational movement of the handlebar at least one of the handles by means of the associated parallelogram guide with the handlebar forming control rod in its skewed position to the steering column axis when turning of the handlebar can be moved approximately parallel, according to patent application G 47923 Π / 63 c (German Auslegeschrift 1253 598).

In a known type of steering handle, the handles with the handlebar are arranged on the handlebar so that they extend in one plane and are rotatable about axes parallel to the steering column axis. The handles are freely rotatable, which gives the vehicle owner the impression of a certain instability of the steering, so that it is not possible for him to actuate the steering exactly (US Pat. No. 2,737,060).

In a further known type of steering handle, the handles are essentially arranged upwardly angled ends of the handlebar. Through this rigid connection of the handles with the handlebars there is the disadvantage that when the steering angle is large, the downward movement Handle assumes a position contradicting the anatomical conditions of the operating hand (German patent specification 935 646). In order to eliminate these disadvantages of the known steering handle, it was proposed according to the main patent to pivot the handles on the handlebars and at least one of the handles by means of a guide that forms a parallelogram with the handlebar Control rod in its skewed position to the steering column axis when turning the handlebar approximately parallel to move, with the control rods alternately depending on the direction of rotation of the handlebars the action of a clock spring by means of a hook piece against each one on the bearing housing the steering column or the collar bolts attached to the handlebars.

Since in practice a sufficiently play-free representation of a parallelogram guide according to the However, the main patent is associated with a relatively high manufacturing cost, is the invention the underlying task of developing a steering handle of the type mentioned at the outset and to do so simplify that it can be produced with the least amount of effort.

This object is achieved according to the invention in that the for moving the handles in Depending on the steering angle provided control rods are designed as cardan shafts, which each via universal joints on the one hand on the pivotable handles and on the other hand on the Bearing housing of the steering column are hinged. Through the use of cardan shafts and universal joints the number of joints compared to the embodiment according to the main patent per se is reduced and at the same time compliance with the smallest manufacturing tolerances with lower manufacturing costs achieved. Another advantage of the invention would be that through the use of cardan shafts the possible steering angle of the handlebars can be increased considerably.

In a particularly useful embodiment of the invention it is also provided that the handlebars in a transverse plane to the steering column axis pivotably attached handles reaching through the handlebars Have approaches through which they are connected to the cardan shafts by universal joints.

In the drawings, an embodiment of the steering handle according to the invention is in schematic Way presented. It shows

F i g. 1 shows a view of the steering handle according to the invention from the driver's point of view when driving straight ahead and in dashed lines when the handlebar is turned counterclockwise by about 110 °,

F i g. 2 shows a plan view of the steering handle according to FIG. 1 seen obliquely from above and in front.

The steering handle according to the invention, which can be used with particular advantage for progressive steering is, consists according to the embodiment of the arranged on a steering column 1, in Top view of a V-shaped handlebar 2, on whose handles 17 and 17 'are arranged at both ends at an angle to the steering column axis.

The handles 17 and 17 'are hinged to the bent, free ends 3 and 3' of the handlebar 2 so that that they can be pivoted in a plane perpendicular to the steering column axis ίο, so that they, as in Fig. 1 indicated by dashed lines, when turning the handlebar substantially approximately parallel to itself be moved yourself. The handles are therefore ' even with a greater steering angle of 90 ° and more, always within easy reach for operating the Handlebar's comfortable position.

To control the adjustment movement of the handles depending on the handlebar deflection Cardan shafts 27 and 27 'are used, each of which has a universal joint 26 or 26' with a bearing housing 14 for the steering column 1 and at the other end via a universal joint 25 or 25 'with the handles 17 and 17 'are connected.

The universal joints 26 and 26 'consist in a known manner each from a joint ball, which over a joint socket is attached to the bearing housing 14 and via a second joint socket rotated by 90 ° is connected to the cardan shaft 27 or 27 '. The universal joints 25 and 25 'on the other Side of the cardan shafts have corresponding joint balls, which also have ball sockets both with the cardan shafts 27 and 27 'and with the rear lugs 8 and 8' of the handles are connected.

It can be seen that when the handlebars deflect from the center position shown, the Handles 17 and 17 'on the cardan shafts 27 and

27 'are pivoted in their pivot bearings on the handlebar 2 so that they are at each steering angle lie in a position parallel to their position in the central position.

Claims (2)

Patent claims: 1. Steering handle for motor vehicles with the side of one arranged on a steering column Handlebar protruding extensions, on each of which a handle is arranged, the handles on Handlebars are pivotably mounted and depending on the rotational movement of the handlebar in each case at least one of the handles by means of the one assigned to it, with the handlebar a parallelogram guide forming control rod in its skewed position to the steering column axis when turning the handlebar approximately parallel displaceable is, according to patent application G 47923 Π / 63 c (German Auslegeschrift 1253 598), thereby characterized in that to move the handles (17 and 17 ') depending on Steering angle provided control rods are designed as cardan shafts (27 and 27 ') which each via universal joints (25 and 25 'or 26 and 26') on the one hand to the pivotable Handles (17 and 17 ') and on the other hand are hinged to the bearing housing (14) of the steering column. 2. steering handle according to claim 1, characterized in that the handlebars (2) in one Handles (17 and 17 ') attached to the steering column axis so as to be pivotable transverse plane the handlebar (2) have penetrating lugs (8 and 8 ') through which they can be connected to the cardan shafts (27 and 27') are connected by universal joints (25 and 25 ').
