Disclosed is an aircraft windshield wiper system, having: a wiper arm; a reversible motor that drives the wiper arm, the motor including: a stator; a rotor configured to rotate relative to the stator; a forward shaft segment that is driven by the rotor and being rotationally connected to the wiper arm; an aft shaft segment that is driven by the rotor, the aft shaft segment including a forward end and an aft end; a ball nut that translates along the aft shaft segment from rotation of the aft shaft segment; a forward stop at a forward end of the aft shaft segment, configured to stop forward translational motion of the ball nut along the aft shaft segment; and an aft stop at an aft end of the aft shaft segment, configured to stop aft translational motion of the ball nut along the aft shaft segment.

The invention relates to a gear motor (1) for a motor vehicle wiper system including an electric motor (2) including a rotor (20) and a rotation shaft (22) fixed to the rotor, a reduction gear mechanism (3) including a worm/worm wheel system, a device for generating an axial load configured to offset axial play of the rotation shaft (22), including a retaining wedge (6) mounted in a sliding manner in a radial direction of said rotation shaft (22), said retaining wedge (6) exerting an axial load on the outer race of a ball bearing (5) configured to guide the rotation shaft. According to the invention, said retaining wedge (6) is arranged in an intermediate position between the seat (40) of the bearing support (4) and the worm (30) directly adjacent to the worm wheel (31), said axial load (Fa) exerted by the retaining wedge (6) on the outer race (51) of the ball bearing (5) being in the direction away from the worm (30).

A roof assembly for forming a vehicle roof of a motor vehicle. The roof assembly may have a panel component at least partially forming a roof skin of the vehicle roof, the roof skin serving as an outer sealing surface, at least one environment sensor configured to send and/or receive electromagnetic signals through a see-through area to detect a vehicle environment, and at least one cleaning feature. The cleaning feature may have a window wiper assembly having two wiper elements which have a common pivot axis, the one wiper element being configured to clean a windshield or a rear window and the other wiper element being configured to clean the see-through area.

The invention relates to a geared motor (1) for a motor-vehicle wiping system comprising an electric motor (2) comprising a rotor (20) including magnetic elements, a stator (21) having the electromagnetic excitation windings of the rotor, a rotary shaft (22) rigidly connected to the rotor, a reduction gear (3) linking the rotary shaft (22) and an output shaft of the geared motor, a casing (4) forming a protective envelope for said reduction gear, or the electric motor (2), and in which said reduction gear (3) includes a worm screw and worm wheel gear, the worm screw (30) being rigidly connected to the rotary shaft of the rotor (22), the worm wheel (31) rigidly connected to an output shaft (8) of the geared motor, bearing means (23, 24) for guiding the rotary shaft of the rotor (22) in rotation in relation to the casing (4), and potentially, a determination device for determining the angular position of the rotor including a multi-pole magnet (5) that is rigidly connected to the rotary shaft (22) of the rotor (20).

Disclosed is a vehicle wiper control device which includes: wiper blades that can be disposed on a surface to be wiped and that perform a reciprocating wiping motion between a lower reversal position and an upper reversal position which are set on the surface to be wiped; an electric motor that reciprocates the wiper blades on the surface to be wiped; a drive portion that drives the electric motor; and a load calculation portion that calculates a load on the electric motor while the wiper blades wipe from the upper reversal position to the lower reversal position. If the calculated load value exceeds a predetermined threshold, the drive portion performs wiper stop processing for stopping the wiper blades at the lower reversal position or at a storage position which is set below the lower reversal position.

A wiper device that includes: a first control section that, during intermittent operation, controls power supply to a drive source such that a wiper blade wipes to-and-fro between a first return position and a second return position on a windshield and stops moving for a predetermined duration at the first return position, and that performs position retention control that controls power supply to the drive source such that the stopped wiper blade is retained at a position at which the wiper blade is stopped; and a second control section that suspends the position retention control by the first control section in a case in which a current flowing in the drive source is detected to have increased by a predetermined value or greater while the wiper blade moves toward the first return position within a predetermined region in a vicinity of the first return position.
