  • Patent number: 9340084
    Abstract: A drive axle for industrial trucks is, by fastening mechanisms, on the one hand able to be connected to the vehicle frame and, on the other hand, connected to the axle housing. Flexible elements that take effect in the main directions of force in such a manner that they are mainly subject to pressure are arranged between the fastening mechanisms and the axle housing.
    Type: Grant

  • Patent number: 9199534
    Abstract: A drive for an industrial truck with at least one drive motor for driving a wheel of the industrial truck and at least one steering motor for supporting a steering movement of the wheel around a steering axle also features a drawbar for guiding the steering or driving movement by applying a load on the drawbar. The drive motor also rotates upon a steering movement of the wheel, whereas the drawbar is connected in a torque-proof manner, relative to the steering axle, with a component also rotating upon a steering movement of the wheel.

  • Patent number: 7784572
    Abstract: A drive unit (1) for an industrial truck comprises a drive motor (2), an electronic steering mechanism (3) being arranged at the periphery thereof. In this way, the drive unit (1) is configured such that it is simpler to assemble and more reliable to operate due to less wiring.

  • Patent number: 7772728
    Abstract: An electric, drive system for floor conveyances with one or more vehicle chassis (3; 10, 11) in active connection with one another allowing relative movement and with at least one electric, drive motor and/or an electric, steering motor, with an electric transverter associated with each of these and an electronic, control system. At least one of these electric or electronic components is designed to be cooled by a liquid and is connected via an associated cooling circuit (5; 12) to at least one cooling device.

  • Patent number: 7621360
    Abstract: A drive unit for a floor trolley, with at least one steered wheel (1), which is attached to a vehicle chassis (3) so that it can swivel about an essentially vertical swivel axis (2), a drive motor (4) with a drive shaft (5) being arranged coaxially with the swivel axis (2). The motor is in driving connection with the at least one wheel (1) via a gear system (10). The drive motor (4) and the gear system (10) are mounted in a common housing (16), consisting essentially of two separate housing portions, namely, a lower and an upper housing (portion 16a, 16b), that can be joined together by a fastening mechanism (18), and is mounted to rotate on the chassis (3) via at least one roller bearing (19). A drive unit is provided that at least one of the two housing portions (16a, 16b) is associated with a drawbar connection (20) formed integrally therewith by way of the housing (16) being swiveled relative to the chassis (3) about the swivel axis (2).

  • Publication number: 20070210644
    Abstract: An actuation device for a brake has an accumulator (14). The accumulator (14), when in a parking brake position, acts on a ball ramp actuator (10) via a connecting element to actuate the brake as a parking brake. If the accumulator (14) is in a released position, an actuator (16) is activated to displace a catch (17) and to hold the accumulator (14) in this released position.
