AI Technical Summary

Technical Problem

Existing devices for opening and closing windows, doors, or sliding roofs in motor vehicles are susceptible to shocks and pressures, leading to noise and vibration issues.

Method used

A device using an integrated sheet steel housing with two shell-shaped halves, supported by elastic support shells that dampen vibrations and provide a compact, stable structure, eliminating distinct magnetic circuit closing brackets and enhancing silencing through enlarged surfaces and hammer-type brush holders.

Benefits of technology

The solution results in a shock-resistant, silent, and resonance-free operation by dampening vibrations and reducing noise, ensuring a stable and compact design.

This problem is solved by the features of the invention. Advantageous embodiments of the invention are set forth in the subclaims. By the use according to the invention of an integrated sheet steel housing with two shell-shaped housing halves made of sheet steel which can be divided in the direction of the motor axis by very simple means from the point of view of manufacturing and assembly technique, the result is a capsule-shaped "lucre", compact, in itself stable and therefore insensitive to shocks and pressures, due to the electric motor with the transmission mechanism locked close to it.
