A powered bogie for a railway vehicle, including one or more motors mounted on the bogie chassis, the front and rear reducing gears being arranged between, on the one hand, a longitudinal plane midway between the two front wheels and midway between the two rear wheels and, on the other hand, a longitudinal plane passing through the front wheel and the rear wheel situated on the same, first transverse side of the bogie is provided.

Motor-driven bogie for a streetcar

A railway vehicle including a plurality of bogies is provided. Each bogie includes a chassis, two front wheels and two rear wheels. For each front wheel and each rear wheel, a guidance device is provided for guiding the wheel in rotation and a primary suspension device of the chassis is provided on the guidance device. At least the primary suspension devices associated with the front and rear wheels are arranged on the same first lateral side of the bogie. The primary suspension devices each include two longitudinal connecting rods, each connected by a first connection point to the chassis and by a second connection point to the corresponding guidance device and at least one resilient component inserted between the two connecting rods to define at least the vertical stiffness of the primary suspension device, the two connecting rods being offset longitudinally relative to one another. Each of the bogies also includes a pivot connection device for connecting the bogie to the railway vehicle.

Railway vehicle comprising pivoting bogies

A bogie for a railway vehicle including a chassis; two front wheels and two rear wheels; and for each front wheel and each rear wheel, a guide for guiding the wheel in rotation and a primary suspension device of the chassis on the guide is provided. At least the primary suspension devices associated with the front and rear wheels arranged on the same first lateral side of the bogie each include two longitudinal connecting rods, each connected to the chassis by a first connection point and to the corresponding guide by a second connection point, and at least one resilient component inserted between the two connecting rods to define at least the vertical stiffness of the primary suspension device, the two connecting rods being offset longitudinally from one another.

Bogie for railway vehicle

A railway vehicle including two end bogies is provided. Each end bogie includes a chassis; two front wheels and two rear wheels; for each front wheel and each rear wheel, guide for guiding the wheel in rotation and a primary suspension device of the chassis on the guide. At least the primary suspension devices associated with the front and rear wheels arranged on the same first lateral side of the bogie include two longitudinal connecting rods, each connected by a first connection point to the chassis, and by a second connection point to the corresponding guide, at least one resilient component inserted between the two connecting rods to define at least the vertical stiffness of the primary suspension device, the two connecting rods being offset longitudinally relative to one another. Each end bogie includes pivot connector suitable for connecting the end bogie to the vehicle.

Railway vehicle comprising pivoting end bogies

A motor bogie for a rail vehicle having an integral low-slung floor, the motor bogie having a frame resting on four wheels via a primary suspension, the frame supporting at least one motor disposed on one side of the frame and connected to at least one wheel via transmission, wherein each wheel has an individual wheel shaft supported by an axle box, and wherein the transmission comprise a gear unit coupled directly to the shaft of the wheel and a telescopic transmission of the type having a double universal joint and disposed between the gear unit and the motor, the gear unit being placed outside the wheel, and having a casing incorporating the axle box of the shaft of the wheel, the casing of the gear unit serving as a support element for supporting a primary suspension member on which the frame bears.
