- the transmission device 34 has an axis of rotation 65 parallel to Y.
- each of the front 37 and rear 38 parts of the frame 30 is assembled with a motor 32 and a separate transmission device 34 .
- the front and rear motors 32, assembled to the front 37 and rear 38 parts of the chassis, are substantially identical and will be described simultaneously below.

- the motor 32 comprises four fixing zones 66, substantially arranged at the vertices of a rectangle.
- Each fixing zone 66 includes an assembly hole 70 intended to cooperate with a fixing rod.
- the bearing surface 68 of the motor 32 is intended to come into contact, in the assembled configuration, with the receiving surface 60 of the front or rear part 37, 38 of the chassis.
- the bearing surface 68 of the motor 32 is substantially horizontal and oriented downwards.
- the support surface 68 is formed of two support strips 72, capable of coming into contact with one of the receiving strips 62 .
- Each backing strip 72 preferably has a shape similar to the corresponding receiving strip 62 .
- the support strips 72 are arranged close to the attachment zones 66 intended to be assembled with the lower limbs 54 of the supports 48, 50 for attachment.
- each fixing zone 66 of a motor 32 is in contact with an upper 52 or lower 54 member of a support 48, 50 for fixing the frame 30.
- a central space 75 is provided along X between said motor 32 and the nearest transverse beam 42.
- the central space is delimited along Y by the fixing lugs 44, 46 connected to the motor.
- central space 75 is open above and below the chassis 30. In particular, the central space 75 is open to the lower space 24 of the motor car 12.
- the transmission device 34 comprises a reaction rod 76, visible on the figure 2 and 3 .
- said connecting rod 76 is offset relative to motor 32 in the transverse direction Y; and one of the mounting brackets, in particular the second bracket 50, comprises a connecting rod attachment 78, disposed between said connecting rod 76 and said motor 32 in said transverse direction Y.
- a connecting shaft (not shown) connects the connecting rod 76 and the connecting rod attachment 78, said shaft comprising two ends respectively assembled to the connecting rod 76 and the connecting rod attachment 78.
- fastener 35 fixedly connects motor 32 to frame 30.
- the fixing element 35 associated with a motor 32 comprises four fixing rods 80, for example of the screw type.
- Each mounting pin 80 is inserted into assembly holes 56 and 70 of both mounting bracket 48, 50 and mounting area 66 of motor 32. In the assembled configuration, each mounting pin 80 extends along X.
- the presence of the receiving surface 60 allows the frame 30 to directly take up the weight of the motor 32 via the support surface 68. This configuration reduces the vertical force exerted on the fixing rods 80 in the assembled configuration, which reduces the risks of breakage of said rods and facilitates their dismantling.
- each support 48 is through; and each fixing rod 80 is associated with a screw head 82 enabling said screw to be maneuvered using a tool.
- each screw head 82 is adjacent to the central space 75 between the motor 32 and the corresponding cross beam 42. As will be described below, this configuration facilitates the removal of said screws.
- the fixing rod is a stud, itself screwed into a threaded cylinder, which makes it possible to avoid having a thread in the engine.
- the safety device 36 is intended to prevent an untimely fall of the motor 32 from the frame 30 during disassembly or breakage of the fixing rods 80.
- the safety device 36 comprises at least one member 84 for blocking the motor 32 and the frame 30.
- the blocking member 84 includes: a first 86 and a second 88 blocking openings, respectively carried by the frame 30 and by the motor 32; and a blocking pin 90.
- the safety device 36 comprises a first and a second substantially identical blocking members 84, which will be described simultaneously below.
- the first blocking opening 86 of each of the first and second blocking members 84 is carried by the upper member 52, respectively of the first 48 and of the second 50 fixing support.
- the second blocking opening 88 of each of the first and second blocking members 84 is carried by a zone 92, secured to the body 64 of the motor and forming a projection relative to said body. Said second opening 88 is through.
- each of the first 86 and second 88 locking apertures extends along Y and said apertures are aligned.
- the blocking pin 90 is able to slide along Y in the first 86 and second 88 aligned blocking openings. In the assembled configuration, said pin 90 is inserted into said openings.
- the blocking member 84 is configured so that the pin 90 can be maneuvered from the central space 75.
- the zone 92 of each blocking member 84 extends into the central space 75 in the configuration Assembly.
- the motor bogie 20 being integrated into the motor car 12, a method of dismantling the motor 32 from below the chassis 30 is carried out in particular according to the following steps: An operator settles in the lower space 24 under the motor bogie 20 , opposite the central space 75 of the engine 32 concerned; then, by maneuvering from said central space 75, the operator partially unscrews the four fixing rods 80 by actuating the screw heads 82. The operator then positions a lifting table (not shown) under the motor 32, in particular under the body 64 of said motor.
- the operator moves the motor 32 slightly along X, so that the support surface 68 of said motor is no longer opposite the surface 60 for receiving corresponding.
- the displacement distance along X is in particular greater than or equal to the dimension 63 of the receiving bands 62 described above.
- the motor 32 is thus released from the vertical stop formed by said receiving 60 and bearing 68 surfaces. Said motor is then lowered into the lower space 24 and possibly moved for maintenance operations. It is then reassembled on the frame 30 by a reverse process.
- a clear central space 75 opposite the element 35 for fixing the engine 32 to the chassis 30 and the safety device 36, facilitates work on said engine, in particular from underneath the car. motor 12.
