Abstract: The invention relates to a locking mechanism for securing a battery pack (20) which is accommodated in an electrical vehicle (12), in particular in an electrical industrial truck, comprising a vehicle-side plug element (26) and a battery plug element (28), which can be plugged together with said plug element (26) and is connected to the battery pack (20). In this case, it is provided according to the invention that the mechanism comprises a locking element (32), which is arranged on the vehicle (12) and can be moved, in particular pivoted, between a battery release position and a battery locking position, the locking element (32) and the vehicle-side plug element (26) being arranged in relation to one another in such a way that the plug-type connection between the vehicle-side plug element (26) and the battery plug element (28) can be produced and released depending on the position of the locking element (32).

Abstract: In an industrial truck, in particular a fork-lift truck, having a vehicle frame and a load pickup means (16), which can be displaced in relation to the vehicle frame, at least one wheel which is closer to the load pickup means and, at a distance from this, at least one wheel (20) which is further away from the load pickup means being provided on the vehicle frame, the wheel axle (18) of at least one wheel (20) being capable of moving in relation to the vehicle frame along a movement trajectory with a movement component which is orthogonal with respect to the standing area of the industrial truck, in addition a loading force (B), which is caused by the tare weight of the industrial truck and a load (L) which may have been picked up by said industrial truck, acting on the at least one moveable wheel axle (18), which loading force changes operationally, the at least one moveable wheel axle (18) in addition has or can have an arbitrarily variable additional force applied to it.

Abstract: A pressure-medium-actuated actuation device, in particular for a vehicle steering apparatus, comprises a double-acting actuator (12) with two active regions (24, 26) acting essentially in opposition, each active region (24, 26) having connected to it in each case a pressure-medium line section (28, 30), by means of which a pressure medium can be supplied to the active regions (24, 26) or can be discharged from these (24, 26), and each pressure-line section (28, 30) which supplies pressure medium to the actuator (12) being connected to a pressure-medium pump (14) coupled to a pump drive (16), by means of which the at least one pressure-medium pump (14) can be driven for the conveyance of pressure medium. According to the invention, the pump drive (16) is designed in such a way that the quantity of the pressure medium conveyed per unit time by the pressure-medium pump (14) can be varied and its conveying direction (I, II) can be reversed.
