The floor module is pre-assembled in a first pre-assembly process and the drive train and the chassis are pre-assembled in a second pre-assembly process. The floor module, the drive train and the chassis are combined and then connected to the shell of the motor vehicle.

The device comprises a sealing sleeve (20) that can be arranged about the facing ends of two tubes (1, 2) and a clamping sleeve (10) into which the sealing sleeve extends. One of the elements comprising the sealing sleeve (20) and the clamping sleeve (10) has at least one retaining member (32A, 32B) capable of engaging, in axial retention inside the clamping sleeve, with a retention surface (1'A, 2'A) of one of the tubes covered by the clamping sleeve.

Pre-assembled blade (20) for fans (10) for cooling the coolant contained inside the radiator (1) of operating machines and / or vehicles, comprising a blade body (20a) rigidly connected to an axial shank (21), a part of which situated radially on the outside of the blade body is in the form of a cylindrical pin (21b); wherein the shank (21) has a part axially on the outside of the blade body in the form of a cylindrical pin (21b), holes (21c) with internal female threading being formed inside the pin (21b); and in that the blade (20) comprises —a blade flange (22) comprising. a hollow cylindrical body (22a), the opposite end bases of which comprise respectively: a flat edge (22b) provided with through-holes (22c). an inset annular seat (22d); a disk (23) provided with through-holes (23a) and an eccentric recess (23d) for stably containing with friction a pin (24) which is also eccentric, for rotationally actuating the blade about its axis; —screws (25) designed to pass through the through-holes (23a) in the disk (23) and mate with the female thread of the holes (21c) in the pin (21b) in order to fix relative to each other the disk (23), flange (22) and pin (21b), thus ensuring a definite angular alignment of the blade relative to the pin (24) during pre-assembly.

A panel mount for supporting an electronic device at a hole in a control panel and mountable with access to only the front of the panel. It has a housing that slides into a tubular elastomeric grommet. During installation, an expander segment of the housing slides within a bulging segment of the grommet to expand the grommet inward of the hole and for retaining the components within the hole. A tubular male pre-assembly segment on the exterior surface of the tubular housing permits the housing to be pre-inserted partially into the grommet without expanding any part of the grommet radially outward in preparation for inserting the assembled housing and grommet into the panel hole. A withdrawal lock prevents the housing from sliding axially out of the grommet after installation. The withdrawal lock includes a shoulder formed on the grommet and a shoulder formed on the housing.

The invention concerns a method which consists in cyclically: transferring a first row of products (3) between the station for preparing said products (6) and the pre-assembly station (7), at a speed V; transferring similarly a second row of products (3) onto said pre-assembly table (7), and in order to manage the docking of said second row with the row of products already set on said pre-assembly table (7), moving said set row at a speed v selected between zero and V, depending on the type or products (3); transferring, as the case may be, another row of products (3) onto the table (7), and, when the number of rows is reached to obtain said layer, transferring said layer onto the setting table (13) of the palletizing station (14). The installation comprises transfer means consisting of pushers (25) and (26) mobile between different stations, driven at suitable speeds. The invention also concerns, at the pre-assembly station (7), a modular endless belt which is supported and moves on a slider bed, said belt being mobile, driven at a speed which is related to that of the pushers (25) and (26).
