Problems solved by technology

[0003] However, it has been found to be disadvantageous in this known embodiment that usually two components that are fixedly connected to each other, especially in the axial direction, are connected to each other in a particularly complex manner, or even during the entire use of the actuator. Unsatisfactory interconnection in the axial direction observed during lifetime
Increased number of components and thus increased manufacturing effort due to hitherto common joining processes, e.g. using threads and / or snap rings and / or press fits, pre-defined positional relationships or mounting clearances cannot be observed or the required positioning accuracy cannot be achieved

Embodiment Construction

[0058] figure 1 The general structure of an actuator 1 according to the invention is shown according to a preferred (first) embodiment, which is designed as a single-motor transmission actuator. Its individual components are explained in detail in the following figures.

[0059] The single-motor transmission actuator 1 has a plurality of components and / or mechanisms and / or elements which are each individually protected subject matter individually and / or also in combination with each other. The same applies to the methods thus performed individually and / or in combination and also to the corresponding methods which, although capable of being carried out by means of the components, mechanisms and / or elements described, are carried out in the same manner as the The components, mechanisms and / or elements are independent and, accordingly, the method can be independently protected.

[0060] The single-motor transmission actuator 1 firstly has a drive unit 2 as an inspectable unit, ...

Abstract

The invention relates to an actuator (1) for selecting and shifting at least two speeds of a transmission, comprising a motor (5) and at least one speed-changing device (4), which converts a motion of the motor (5) into shifting motion and / or into a selecting motion of a shifting shaft (20), wherein at least two components of the actuator (1) connected to each other are fastened to each other by means of a plastically shaped retaining region (95). The invention further relates to a method for connecting two components of such an actuator (1).

Description

technical field [0001] The invention relates to an actuator for selecting and shifting at least two gears of a transmission, said actuator having (preferably exactly one) motor, such as an electric motor, and at least one transmission / transmission mechanism, so The transmission / gear mechanism converts the movement of the motor into a shifting movement of the shifting shaft and / or into a selection movement of the shifting shaft. The actuator is preferably designed as a shift transmission actuator and more preferably as a single-motor transmission actuator. The present invention therefore also relates to a single-motor transmission actuator and to its use for shifting and selecting a transmission and optionally additionally for actuating a clutch. Background technique [0002] Such actuators / shift transmission actuators are known from the prior art and are disclosed, for example, by WO 2014 / 177366. In this case, the transmission actuator has exactly one motor and a screw dri...
