Embodiment Construction

[0026] figure 1 An electric drive mechanism for a forklift is shown. The drive mechanism consists of a transmission 1 on the left, a transmission 2 on the right, an electric motor 3 on the left, an electric motor 4 on the right and a multi-disc brake 5 .

[0027] figure 2 and image 3 A multi-disc brake 5 and its structural environment are shown. The housing of the left transmission 1 is connected to the housing 15 of the left electric motor 3 . The housing of the right transmission 2 is connected to the housing 16 of the right electric motor 4 . The housings 15 and 16 of the electric motors 3 and 4 are fixedly connected to one another on the sides facing away from the transmission 1 and 2 respectively. Housing 15 of electric motor 3 on the left accommodates multi-disc brake 5 . The multi-disc brake 5 itself consists of a first disk pack assembly 6 , a second disk pack assembly 7 , a ball ramp actuator 8 , a positively acting actuating part 9 and a negatively acting act...

Abstract

The invention relates to a multi-disc brake with a first disc pack assembly and a second disc pack assembly which are coaxial with each other, the first disc pack assembly is composed of a first outerdisc pack and a first inner disc pack connected with a first shaft, and the second disc pack assembly is composed of a second outer disc pack and a second inner disc pack connected with a second shaft. A radial feed channel is formed in at least one component of an actuator of the multi-disc brake, cooling fluid can be fed to an radially outer end of the radial feed channel via a radial feed line, a radially inner end of the radial feed channel is connected to at least one output line in a first and / or second coaxial opening in the first shaft and the second shaft, and one or more radial outflow channels are formed in the first shaft and the second shaft and led from the first coaxial opening to the first inner disc pack and from the second coaxial opening to the second inner disc pack.

Description

technical field [0001] The invention relates to a multi-disc brake, which has: a first friction plate set assembly and a second friction plate set assembly coaxial with each other, and the first friction plate set assembly consists of a first outer plate that is non-rotatable and axially movable. The friction plate set is composed of the first internal friction plate set that is non-rotatably connected to the rotatably driven first shaft and can move axially, and the second friction plate set assembly is composed of the non-rotatable, axially movable The moving second outer friction plate set is composed of an axially movable second friction plate set that is non-rotatably connected to a rotatably driven second shaft that is coaxial with the first shaft, wherein, The first plate pack assembly and the second plate pack assembly are surrounded by a common housing; the actuator is axially arranged between the first plate pack assembly and the second plate pack assembly and can be...
