FIELD: process engineering.
SUBSTANCE: set of inventions relates to wiper design and components. Connection device has connector (18) secured to wiper carcass-less brush and adapter (16) articulated therewith. Connection element (14) is connected with wiper brush lever (12) with adapter (16) fitted in its channel of U-like cross-section. Said adapter has flexible tab with button arranged at its top wall to lock it in said section of connection element. Said connection element (18) has mid lengthwise rib (28) extending in the brush lengthwise direction. Said rib supports hinge pin (30) extending at its lengthwise sides is fitted in seats at adapter (16) sides elastically pliable in lateral directions. Adapter (16) outer walls feature common depth. Female seats are composed of blind holes with their cylindrical surface making radial surfaces of sliding. Their end surfaces make axial surfaces of sliding (48, 50) are mirror-finished. Said surfaces feature roughness with mean arithmetic channel deflection Ra smaller than 0.2 mcm. Said surfaces are single contact surfaces between connection element (18) and adapter (16).
EFFECT: lower friction, sufficient stiffness, simplified design.
