Transmission control device

Abstract

The invention relates to a control device (10), in particular an integrated control device for transmission systems of motor vehicles, comprising a base part (20) and a cover part (28), a circuit carrier (18), and at least one via (12) for connecting to a structure (48) of modular connection technology. The cover part (28) and the base part (20) receive a filling medium (22). The cover part (28) has at least one section (32), (40), (44) that can be deformed in a deformation direction (34).

Description

technical field

[0001] The invention relates to a controller, in particular an integrated controller for a gearbox of a motor vehicle. Background technique

[0002] Controllers, in particular gearbox controllers such as are used in automatic gearboxes of motor vehicles, are exposed to high mechanical loads. The controller is partly embodied within the vehicle's automatic transmission and is thus exposed to extremely aggressive media such as, for example, transmission fluid (ATF = Automatic Transmission Fluid). A control unit for a motor vehicle gearbox essentially comprises a circuit carrier, for example via electrical contacts in the form of crimp connections and feed-through contacts blown into the housing of the control unit (Durchkontaktierung), such as nickel-iron-pin (Ni-Fe-Pin) contacts. The blown-in feedthroughs have the particular advantage that they are hermetically sealed and enable outwardly guided electrical contacts, so that the feedthroughs of the gearbox co...

Examples

Embodiment Construction

[0019] according to figure 1 The diagram in FIG. 1 shows a first embodiment variant of the controller provided according to the invention.

[0020] from according to figure 1 It can be seen in the illustration that an integrated controller, in particular a controller for a gearbox or an automatic gearbox of a motor vehicle, has at least one pin-shaped feed-through in the bottom part 20, which is preferably composed of Made of plastic material. The individual pin-shaped feedthroughs 12 are electrically insulated from one another, wherein the pin-shaped feedthroughs 12 are designed to be solderable or laser weldable and to enable a crimp connection. The pin-shaped feedthroughs 12 are either inserted into the base part 20 made of plastic or sprayed into the base part by means of the seal 14 . The pin-shaped feedthrough 12 is connected via an electrical connection 16 to an electrical component, which is arranged on the upper side of the circuit carrier 18 . The bottom part 20 ...
