Embodiment Construction

[0025] figure 1 Such as figure 2 , image 3 and Figure 4 Also a partial top view of an embodiment of the rotor 1 according to the invention. The rotor 1 has an inner rotor ring 2 , which forms a shaft seat on the peripheral surface of the inner ring for mounting on a drive shaft or a driven shaft. A plurality of rotor segments 3 are separated from one another by gaps 4 or spaces provided for insertion of magnets 5 , wherein rotor segments 3 are elastically connected to rotor inner ring 2 via webs 6 . The web 6 is designed as an S-shaped bent spring.

[0026] An oval or egg-shaped cutout 7 is provided centrally in the rotor section 3 as a tool receptacle into which a tool can be inserted for mounting the rotor 1 . The corresponding installation procedure is then followed by image 3 and Figure 4 A detailed description. Furthermore, the rotor segment 3 is essentially trapezoidal, viewed in the axial direction of the rotor (ie in the plan view shown here), so that the ...

Abstract

The present invention relates to a rotor (1) for a motor vehicle actuator comprising an inner rotor ring (2) and, attached thereto, rotor segments (3), which are separated from one another in the circumferential direction by gaps (4), wherein the gaps (4) are made of such a size as to each receive a magnet (5) and are configured such that, during operation, the magnets (5) point substantially in a radial direction in the manner of spokes, wherein at least one of the rotor segments (3) is attached to the inner rotor ring (2) by way of an arm (6), which has such material properties and deformation characteristics that, after lengthening (delta(L)) as a result of a positional displacement (delta(D)) of the rotor segment (3) radially outwards, it reverts to its original form when the force responsible for the positional change no longer occurs. The present invention also relates to an actuator or an electric machine having such a rotor (1) and also to an associated assembly method.

Description

technical field [0001] The invention relates to a rotor for a motor vehicle actuator, said rotor having an inner rotor ring and rotor segments mounted thereon, said rotor segments being separated from one another in the circumferential direction by gaps, wherein the gaps are dimensioned And are configured to receive one magnet in each case, so that the magnets are spoke-shaped and point substantially in a radial direction during operation. Furthermore, the invention relates to an actuator or electric machine with such a rotor, and a method for its assembly. Background technique [0002] Motor vehicle actuators, especially brushless DC motors, should operate in fluids such as oil or brake fluid. In the case of motor vehicle actuators arranged in spokes, the magnets are arranged in the form of spokes in the laminated core (rotor or rotor part). According to the prior art, during the production of such actuators, the magnets are pushed into the lamination stack, disadvantageo...
