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.

Device for holding a load on a load support of an industrial truck

Driving system for a an industrial truck with a combustion engine, a two-branch gear transmission whose first shaft is coupled to the combustion engine, whose second shaft is coupled to a change-over transmission, whose outlet acts on the driven wheels of the industrial truck via a collecting transmission, an electric transmission of which a first electric machine cooperates therewith, with respect to the torque, using the two-branch gear transmission, and a second electric machine is coupled via at least one collecting transmission to the driven wheels, the two-branch gear transmission producing a constant torque ratio between the first electric machine and at least the first and second shaft and an electrical circuit arrangement electrically coupling the electric machines and being connected to an electric accumulator,

Driving system for an industrial truck

A driving system for an industrial truck, comprising: a combustion engine, an electric motor fed from a battery, a gear assembly the inputs of which are coupled to the shaft of the combusion engine and the electric motor and the output of which is coupled to the driven shaft of the driving system.

Driving system for industrial trucks

A driving system for an industrial truck, comprising: a combustion engine; a two-branch gear transmission the input of which is coupled to the shaft of the combustion engine and the outputs of which are coupled to a primary shaft and a secondary shaft which are at a fixed speed ratio to each other; an adjustable transmission in the course of the secondary shaft; a gear assembly the inputs of which are coupled to the primary and secondary shafts; a change-over transmission the input of which is coupled to the output of the gear assembly and the output of which is coupled to the driven shaft of the driving system.

A driving system for an industrial truck having a driving device and at least one unit for working motions of the industrial truck, comprising: A combustion engine; an adjustable transmission coupled to the engine shaft; a gear assembly the first input shaft of which is directly coupled to the shaft of the combustion engine and the second input shaft of which is coupled to the driven shaft of the adjustable transmission; an electric motor the shaft of which is coupled to a third input shaft of the gear assembly; a change-over transmission between the driven shaft of the gear assembly ( ) and the driving wheels of the industrial truck; a battery which is connected to the electric motor via an electronic power unit; a sensor system which measures at least the speeds of the combustion engine, the electric motor, and the output shafts of the change-over transmission and, if necessary, the charging state of the battery and generates appropriate output signals; a shaft coupled to the driving system for driving the unit for the working motions of the industrial truck; a governing device which controls the speed of the motors and the gear ratio of the adjustable transmission and actuates the rotary brake and shifts the change-over transmission according to the desired-value signals of the desired-value transmitters actuated by the driver of the industrial truck and on the basis of the output signals of the sensor system.
