Abstract
A ball-joint assembly (34, 36, 38) of a crank (30, 32) and a connecting rod (26, 28) of a windshield wiper module, comprising a crankpin (40) fixed to the crank (30, 32) and a ball-joint housing comprising a socket (42) being arranged to receive the crankpin (40), said socket (42) being fixed in an opening (46) of an end of the connecting rod (26, 28), wherein the socket (42) is made in two parts (48, 50) assembled one with the other with a first part (48) being overmolded on the opening (46) of the end of the connecting rod (26, 28) and a second part (50) being fitted on the crankpin (40), said first part (48) having a hole (49) configured to receive the second part (50).
Claims13
A ball-joint assembly of a crank and a connecting rod of a windshield wiper module, comprising a crankpin fixed to the crank and a ball-joint housing including a socket being configured to receive the crankpin, the socket being fixed in an opening disposed at an end of the connecting rod, wherein the socket is made in two parts assembled one with the other, with a first part being overmolded at the opening of the end of the connecting rod and a second part being fitted on the crankpin, the first part having a hole configured to receive the second part.
The ball-joint assembly of claim 11, wherein the second part is fabricated from a material with a lower coefficient of friction than the material from which the first part is fabricated.
A vehicle comprising a windshield wiper module with a ball joint assembly, wherein the ball joint assembly includes a crankpin fixed to the crank and a ball-joint housing including a socket being configured to receive the crankpin, the socket being fixed in an opening disposed at an end of the connecting rod, wherein the socket is made in two parts assembled one with the other, with a first part being overmolded at the opening of the end of the connecting rod and a second part being fitted on the crankpin, the first part having a hole configured to receive the second part.
A method for assembling a windshield wiper module with a ball-joint assembly, the method comprising:
- overmolding a first part of a socket on the end of a connecting rod of the windshield wiper module,
- fitting a second part of the socket on a crankpin of a crank of the windshield wiper module, and
- a step of joining the connecting rod and the crank by snapping the two parts of the socket together.
