Embodiment Construction

[0025] First of all, it should be noted that in different described exemplary embodiments, the same components have the same reference numerals or the same component names, and may have different reference numerals. The disclosure of a component contained in the specification can be similarly applied to another component having the same reference numeral or the same component name. In addition, terms such as "top", "bottom", "rear", "front", "side", etc. selected in the specification for indicating position refer to figures directly described and shown, and when the position occurs When changed, it can be similarly applied to the new location.

[0026] figure 1 Shown is a rotor 1a for an electric machine comprising a rotor shaft 2a, a rotor laminate core 3 comprising a large number of rotor laminations 4 and a first rotor holder 5a and a second rotor holder 6a With a press fit on the rotor shaft 2a, the first rotor holder 5a is arranged adjacent to the rotor laminated core ...

Abstract

The invention specifies a rotor (1, 1a . . . 1f) for an electrical machine (14), which rotor comprises a rotor shaft (2, 2a . . . 2f), a rotor laminated core (3), which sits on the rotor shaft (2, 2a . . . 2f) with a press fit, a first rotor holder (5a . . . 5c), which is arranged adjacent to the rotor laminated core (3) on a first side thereof, and a second rotor holder (6a . . . 6d), which is arranged adjacent to the rotor laminated core (3) on a second, opposite side thereof. Furthermore, the rotor comprises a first shaft securing ring (7), which sits in a first groove of the rotor shaft (2, 2a . . . 2f) and axially secures the rotor laminated core (3). In addition, the invention specifies an electrical machine comprising a stator (15) and a rotor (1, 1a . . . 1f) of said type, and a vehicle (16) with at least two axles, at least one of which is driven. The driving of the vehicle (16) is performed at least partially or temporarily by the electrical machine (14) of the above mentioned type.

Description

technical field [0001] The present invention relates to a rotor for an electric machine, the rotor comprising: a rotor shaft; a rotor laminated core which is press-fitted on the rotor shaft (and has a plurality of rotor laminations); a first rotor holder in which a first side disposed adjacent to the rotor laminate; and a second rotor retainer disposed adjacent to the rotor laminate on an opposite second side thereof. Furthermore, the invention relates to an electric machine comprising a stator and a rotor of the above-mentioned type, the rotor being mounted rotatable with respect to the stator about an axis of rotation of the rotor. Finally, the invention relates to a vehicle having at least two axles, at least one of which is driven, wherein said driving is performed at least partially or temporarily by an electric machine of the above-mentioned type. Background technique [0002] When mounting the laminated rotor core on the rotor shaft, the rotor laminations are pressed...
