Problems solved by technology

[0020] Another disadvantage in this case is that once a 90° angle is reached between the tractor unit and the trailer, the lever or levers react against the axle or axles to be steered, which of course is not desired
[0022] Another disadvantage of known steering mechanisms is that they cannot be used on trailers such as semi-trailers with an extendable chassis of adjustable length because of the distance between the front turntable bearing and the extendable part by which the trailer is connected to the tractor unit is variable

Embodiment Construction

[0057] Figures 1 to 3 The shown steering mechanism 1 according to the invention is used in this example to steer a rotatable steering shaft 2 of a trailer 3 , such as a semitrailer or trailer, which is pulled by a tractor unit 4 .

[0058] The steering mechanism 1 primarily comprises a swivel bearing 5 having a first swivel bearing part 6 and a second swivel bearing part 7 which are rotatable relative to one another.

[0059] The first slewing bearing part 6 can be connected to the trailer 3 and the second slewing bearing part 7 can be connected to the tractor unit 4 .

[0060] In this example the turntable bearing components 6 and 7 are actually fixed to the trailer 3 and tractor unit 4 respectively.

[0061] Typically the first turntable bearing part 6 will be attached to the trailer 3 and it is concentric with the connection part of the trailer 3 to the tractor unit 4, typically eg in the form of a king pin.

[0062] Furthermore, the steering mechanism 1 according to the ...

Abstract

A steering mechanism for a drawn vehicle to steer one or more turnable steered axles that at least has: DEG A slewing bearing. DEG A rocker that is fitted around a vertical shaft and is turnable. DEG A cable whose ends are connected to the rocker on either side of the vertical shaft and which is fitted around the slewing bearing to transmit a turn of the slewing bearing to the rocker; and, DEG A tackle at each end of the cable with a fixed pulley that can be coupled to the drawn vehicle, and a movable pulley on the rocker.

Description

technical field [0001] The invention relates to a steering mechanism for a trailer for steering one or more rotatable shafts when cornering by mutual cornering motion between the trailer and the tractor or tractor unit. Background technique [0002] According to the prior art, there are many steering mechanisms used on trailers to steer the axle. [0003] More specifically, in known steering mechanisms, a first slew bearing or wire pulley is typically rotated in response to turning or cornering motion of the tractor unit relative to the trailer, which is then translated into rotation of a second wire pulley or slewing bearing, which directly causes a or multiple steering shafts to steer. [0004] To achieve the aforementioned transmission and conversion of rotation, one or more cables or rods are often used to connect the first and second turntable bearings or wire pulleys to each other. [0005] Consequently, the force required to turn the steering axle due to the relativ...
