Abstract
The subject matter of the invention is a trackless tugger train having at least one transportation module and at least two axle modules. Each transportation module is arranged between two axle modules, wherein each axle module has a wheel axle and a steering device for steering the wheel axle, wherein the steering devices of the axle module are embodied in each case in such a way that each steering device steers the axle module which is assigned to it, independently of a steering device of another axle module.
Claims15
A trackless tugger train, comprising:
- at least one transportation module;
- and
- at least two axle modules;
- wherein the at least one transportation module is arranged between two of the axle modules;
- wherein each axle module has a wheel axle and a steering device for steering the wheel axle;
- wherein each steering device of the respective axle module is embodied in each case in such a way that the steering device steers the respective axle module independently of the steering device of another one of the axle modules;
- wherein the axle modules each have a first cantilever arm and a second cantilever arm, wherein the first cantilever arm and second cantilever arm are connected to the wheel axle via an articulated connection;
- wherein the articulated connection has a first vertical pivoting joint and a second vertical pivoting joint, wherein the first and second vertical pivoting joints each have a rotational axis which is embodied vertically with respect to a longitudinal extent of the cantilever arm, wherein the first cantilever arm is connected to the wheel axle via the first vertical pivoting joint, and wherein the second cantilever arm is connected to the wheel axle via the second vertical pivoting joint;
- and
- wherein the articulated connection has a horizontal pivoting joint, wherein the horizontal pivoting joint has a rotational axis which extends transversely with respect to the direction of travel of the tugger train at least in the case of straight-ahead travel of the tugger train.
