Definitions
- the present invention relates to a bogie for railway vehicles, including vehicles for light or conventional metropolitan networks.
- Such a transmission normally includes a reduction unit and one or more couplings operable to compensate for relative movements between the motor and the axles.
- the object of the invention is to provide a bogie for railway vehicles which is extremely simple and safe in operation, and eliminates the disadvantages of prior art bogies listed above.
- the bogie for railway vehicles which includes a rigid chassis, at least two pairs of wheels with each wheel fixed to a corresponding axle, at least one of the wheels being driven by a corresponding drive motor, and which also includes resilient suspension means between the chassis and the axles, and is characterised in that a structure is provided between the chassis and the axle of the at least one driven wheel, the structure being mounted by means of an articulation pin on the chassis and connected thereto by the suspension means, the said motor being arranged with its centre of gravity lying substantially on the axis of the articulation pin.
- Such a bogie achieves the result of carrying the weight of the drive motor, or motors, so that they are entirely suspended while a considerable portion of the weight of the reduction unit is also suspended so that the transmission means do not have to absorb relative movements between the axle and the chassis due to the primary suspension of the bogie.
- the invention thus simplifies the problem, enabling the motor to be entirely suspended, the reduction unit to be semi-suspended and the drive to be transmitted directly from the motor to the reduction unit and from this to the wheel.
- the chassis of a railway bogie is generally indicated 5 and includes a pair of robust symmetrical longitudinal members 6, of inverted-U shape, of which only part of one is visible in the drawings.
- the longitudinal members 6 are connected to each other by at least two cross-members 4, each of which may be shaped, for example, like a tubular bar.
- the bogie includes two pairs of wheels 10.
- One end of a longitudinal member 6 is illustrated schematically in the drawings and a structure 8, commonly known as a "reduction unit” and which acts as a wishbone, is fixed to the said end by means of an articulation pin 7.
- the structure 8 encloses a speed reducer 20 and houses bearings 14 and 15 carrying an axle 9 on which a wheel 10 is mounted.
- the two wheels 10 are therefore independent. This is particularly useful both for high-speed railway vehicles and for vehicles for city and suburban lines which are often required to travel on tortuous networks.
- the independent wheels 10 avoid the risk of snaking movements caused by the cone angle of the wheel rims and therefore avoid any resulting transverse instability of the bogie.
- bogies with independent wheels 10 eliminate the anti-steering effect of the axle 9, which is due to the different developments of the inner and outer tracks 13, and therefore any longitudinal slippage between the wheels 10 and tracks 13. In this way, any annoying flats are eliminated from the rolling face of the wheel, thus reducing the need for expensive re-turning of the wheels 10.
- a brake disc 16 is securely fixed to one end of the axle 9, in the case described the axle 9 inwards of the chassis 5.
- a brake calliper 17, acting on the disc 16, is carried by the structure 8.
- the usual primary suspension assembly for the bogie, generally indicated 11, is also fixed to the ends of the longitudinal members 6.
- the assembly 11 includes, in particular, resilient suspension means of any type, operable to ensure the optimum suspension of the vehicle and acting through a fulcrum 21 on an arm 18 fixed to the structure 8.
- a drive motor 12 for the wheel 10 is mounted on the side of the structure 8 ( Figure 1), its position being fixed so that its axis of rotation, on which its centre of gravity also lies, coincides with the axis of the pin 7 articulating the chassis 5 to the structure 8.
- the speed reducer 20 is operable to reduce and transmit the rotation from the shaft of the motor 12 to the axle 9 and thereby to the wheel 10. Therefore the weight of the motor 12 bears only on the primary suspension 11.
- the need is eliminated for any devices on the bogie to compensate for any relative movements between the motor 12 and the wheel 10 due to the primary suspension.
- the geared drive transmission unit is carried by the same structure 8 as that which supports the motor 12, eliminates the need for devices to compensate for relative movements.
- the structure 8 is perfectly adapted for the independent drive of each wheel 10 of the bogie, thereby satisfying the requirements of high-speed vehicles and those of suburban vehicles.
