摘要:
The invention is referred to a DC motor arrangement for an automotive wiper. This DC motor arrangement comprises a first portion of a housing (1) and a second portion of a housing (12), a DC motor (2) located inside the first portion of the housing (1), the DC motor (2) comprising a first power line (2a) and a second power line (2b), and a filter unit (30) associated to the DC motor (2). The filter unit (30) comprises: a first filter means (3) connected in series with the first power line (2a), a second filter means (4) connected in series with the second power line (2b), a first portion (5) of a metallic plate (56) connected to the first filter means (3), a second portion (6) of a metallic plate (56) connected to the second filter means (4). The first portion (5) of the metallic plate (56) and the second portion (6) of the metallic plate (56) are electrically connected to a common substrate (8), and respectively connected in series to the second portion of the housing (12).

The invention relates to a drive apparatus (1) for operating an element in a motor vehicle, in particular a wiper arm, having a housing (2), an electric motor, a gear wheel (4) which can be driven in a rotatable manner by the electric motor, having a switching disc (6) which is arranged on the gear wheel (4) and having at least one sensing finger (7), which makes contact with the switching disc (6) as a sliding contact, for generating a position-dependent electrical signal. According to the invention, provision is made for damping means (13) which are composed of a vibration-damping material for acoustically decoupling the sensing finger (7) to be assigned to the sensing finger (7). The invention also relates to a window wiper apparatus.
