- - Figure 3 is a perspective view illustrating the second and third step of the method according to the invention
- - Figures 4 and 5 are perspective views illustrating the fourth step of the method according to the invention
- - Figure 6 is a perspective view illustrating the fifth step of the method according to the invention
- - Figure 7 is a detailed perspective view of the underside of the arrangement during the fourth step of the method
- - Figure 8 is an exploded perspective view of a second arrangement according to the invention.
- the arrangement 10 allows the connection of a reservoir 12 for supplying brake fluid to a longitudinal master cylinder 14 for braking a motor vehicle.
- At least one lower supply pipe 16, which is linked to the reservoir 12, is intended to be received in a bore 1 8 complementary supply to the master cylinder 14.
- Means 20 for vertical immobilization are also interposed between the pipe 16 and the master cylinder 14.
- the arrangement 10 conventionally comprises two pipes 16 each intended to penetrate a bore 18 associated with the master cylinder supply 14. Each bore 18 is intended to supply fluid braking an associated internal chamber of the master cylinder 14.
- a master cylinder 14, more commonly known as a "tandem" master cylinder, is intended to supply brake fluid under pressure to two independent braking circuits of the vehicle in which it has climbed.
- the reservoir 12 carries the pipes 16. It is moreover immobilized on the master cylinder 14 by means of a pin. The mounting of such a pin is particularly difficult to achieve on an industrial scale.
- the design according to the invention is particularly advantageous in that it allows rapid and standardized mounting of a reservoir 12, whether it is an independent reservoir 12 or a reservoir 12 fixed to the master cylinder 14 This design makes it possible to mount the reservoir 12 of industrially, i.e. on an automated manufacturing line.
- the arrangement 10 comprises an intermediate base 22, which is connected to the reservoir 12 by at least one nozzle 24, which comprises the supply pipe 16, and which i is capable of being lowered vertically onto the master cylinder 14 then immobilized on the master cylinder 14 by means of vertical immobilization means cooperating by direct snap-fastening with the master cylinder 14, to allow rapid fixing of the pipe 16 on the master cylinder 14.
- the base comprises two nozzles 24 which each communicate with a pipe 16. More particularly, the reservoir 12 is fixed to the base 22, the nozzles 24 of the base being received and in particular fitted into the reservoir 12. The base 22 is interposed between the reservoir 12 and the master cylinder 14.
- the fixing of the reservoir 12 on the base 14 can be ensured by the sole nozzles 24.
- any other embodiment of this attachment can be envisaged.
- the attachment of the reservoir 12 to the base is compatible with different types of tanks 12. This configuration allows the mounting of different reservoirs of different shapes and capacities, each adapted to a particular vehicle, on the base 14.
- the base is also particularly suitable for an assembly comprising an independent reservoir 12.
- the reservoir 12 can be independent of the base 24, the nozzles 24 of the base 22 being connected to a nozzle (not shown) of an independent reservoir via an independent tube (not represented).
- the means for vertical immobilization of the base 22 include at least two arms 26 which extend substantially vertically towards the master- re cylinder 14 from a longitudinal edge 30 of the base 22 and an arm 28 which extends substantially vertically towards the master cylinder 14 from an opposite longitudinal edge 32 of the base 22.
