Abstract
The invention concerns a crank pin for a connecting rod of a wiper-actuating linkage system, the crank pin being configured to be received in a complementary inner cavity of a ball joint of the linkage system, and comprising a truncated spherical portion having at least one spherical sector and at least one truncated sector. The invention also concerns a complementary ball joint. The invention also concerns a corresponding linkage system and the method for assembling a connecting rod of such a system.
Claims15
A crank pin of a wiper linkage system, comprising:
- a connecting rod associated with the crank pin;
- the crank pin being configured to be received in a complementary internal cavity of a ball joint housing of the wiper linkage system, wherein a truncated spherical portion has a spherical sector and a truncated sector, and
- the crank pin having opposing cylindrical ends with a first longitudinal end portion and a second longitudinal end portion, where the truncated spherical portion is situated axially between the opposing ends of the first longitudinal end portion and the second longitudinal end portion.
A method for assembling a connecting rod of the linkage system of a wiper actuating linkage system, having a ball joint housing at one longitudinal end, wherein the method comprises:
- inserting a crank pin into an internal cavity of the ball joint housing that is carried by the connecting rod through a relative translational movement, such that a spherical sector of a truncated spherical portion of the crank pin is arranged next to a second opening portion of the internal cavity of the ball joint housing, and such that the truncated sector of the truncated spherical portion of the crank pin is arranged next to a first, holding portion of the internal cavity of the ball joint housing;
- and
- carrying out a relative rotational movement between the crank pin and the ball joint housing, as far as a predefined angular assembly position in which the spherical sector of the truncated spherical portion of the crank pin is next to the first holding portion of the internal cavity of the ball joint housing.
