The invention relates to a windscreen wiper motor (10), having a housing (12) for accommodating a gearing arrangement which comprises a gear wheel (20) rotatably mounted in a shaft (13), which gear wheel has, on its outer circumference, a toothing (21) which interacts with a counterpart toothing (19) on a drive shaft (15), wherein the shaft (13) is received in a mount (22; 22a to 22c), which is constructed as a bore, of the housing (12) in an eccentric bush (25; 25a to 25c) for setting the distance (a) between the shaft (13) and the drive shaft (15), and wherein a press fit is formed at least in regions between the mount (22; 22a to 22c) and the eccentric bush (25; 25a to 25c).

Electromotive auxiliary drive, particularly a wiper drive, with an electric motor and a downstream gear forming an output shaft of the auxiliary drive, presenting at least two gear stages arranged in series in a drive train between the electric motor and the output shaft, of which one first gear stage is designed in the manner of a worm gear consisting of a worm and of a gearwheel or worm wheel interacting with this worm.

The invention concerns an output element (15; 151) for a motorisation device (1) for driving at least one windscreen wiper arm of a motor vehicle, comprising an output shaft (17; 171) and a toothed wheel (40) integral to and coaxial with the output shaft (17; 171), characterized in that the output shaft (17; 171) is made of plastic material and in that the output element (15; 151) comprises a metallic insert (16; 161; 162; 163), the plastic material of the output shaft (17; 171) being moulded partially over the metallic insert (16; 161; 162; 163), revealing an insert head (25; 251) protruding from the end of the output shaft (17; 171) and intended to connect to a windscreen wiper element in order to drive this in rotation.

The invention also concerns a motorisation device (1) and a method for production of an output element (15; 151).

A wiper system (10) for a motor vehicle, having at least one pantograph wiper arm (20), having a drive arm (22) which can be driven in a predefined angular range (32) by an output shaft (24) of a drive unit (30), wherein the output shaft (24) is pivotably accommodated in a drive bearing (42) arranged on a bracket (40) and the bracket (40) is designed to be fixed to a body of a motor vehicle, the drive arm (22) is fixed directly to the output shaft (24) and the latter is drivable oscillating pivotably about its longitudinal central axis (26) by means of the drive unit (30).
