Latest Patents
One of Dorr's latest patents is a drive unit for a wiper system of motor vehicles. This invention discloses a connection and a two-step method of manufacturing a drive unit for a wiper arm system. The system consists of a wiper shaft mounted in a bore through a crank arm. The wiper shaft is designed with a groove within the thickness of the crank arm, and material from one surface of the crank arm is displaced to create an annular recess. This design allows for the crank arm material adjacent to the groove to be radially displaced into a groove formed in the wiper shaft, creating an axial holding element. The radial distance R1 of the recess from the crank arm bore is substantially equal to the axial distance A1 of the groove below the crank arm surface, facilitating the extruding process. Additionally, knurled areas on the shaft on either side of the groove are press-fit into the crank arm bore as the first step in assembling the shaft to the crank arm, bringing a flange into abutment against the other surface of the crank arm.
