Embodiment Construction

[0039] Figure 1-3 A drive system 1 according to the invention, arranged to drive a water pump P, is shown.

[0040] The drive system 1 includes a drive shaft 10 , a housing 20 , a bearing 30 , a drive belt 50 and a flange 60 . The shaft 10 centered on the central longitudinal axis X1 drives the water pump P housed in the housing 20 . Bearing 30 includes a stationary inner ring 32 and a rotating outer ring 40 centered on axis X1.

[0041] The drive shaft 10 is rotated about the axis X1 by means of a flange 60 which is driven by a rotating ring 40 which is driven by a belt 50 . In other words, the belt 50, the rotating ring 40, the flange 60 and the shaft 10 are rotationally fixed about the axis X1. The shaft 10 comprises a cylindrical portion 11 centered on the axis X1. On the opposite side of the pulley P along the axis X1 , the shaft 10 has an end 12 to which the flange 60 is fitted. This end 12 comprises a fluted part 13 , a substantially convex part 14 and two grooves...

Abstract

The present invention provides a system (1) for driving a water pump (P). The system includes a driveshaft, a case containing the water pump, a bearing including a stationary ring that is stationary relative to the case and a rotating ring secured in rotation with the driveshaft. The system further includes a drive belt, at least one rolling path for the drive belt, the rolling path being secured in rotation with the rotating ring, and a flange transmitting the torque from the rotating ring to the drive shaft. The flange is made from plastic and is overmolded both on the rotating ring and on the driveshaft. The invention also relates to a mounting method for such a system.

Description

technical field [0001] The present invention relates to a system for driving a water pump, and a method for installing such a system. Background technique [0002] In a known manner, the water pump is driven using a drive system comprising a pulley fastened to the drive shaft of the pump and a belt mounted on the pulley to transmit torque and rotational movement. Bearings are usually interposed between the drive shaft and the pulley. The transmission of torque requires a very low concentricity tolerance between the rotating ring of the bearing and the drive shaft. The diversity of components in the assembly of the drive system increases the risk of concentricity errors. [0003] EP-A-1,788,254, FR-A-2,979,395 and FR-A-2,979,397 describe different systems for driving water pumps. Each of these systems includes a metal flange connecting the drive shaft to the rotating ring of the bearing. The rolling path of the belt is formed by a rotating ring or flange, thereby performi...
