The 100% low floor tramcar non-power bogie comprises a bogie framework; one anti-twisting device for regulating relative positions of the bogie framework and a vehicle body is arranged at the front end and the rear end of the bogie framework respectively. According to the 100% low floor tramcar non-power bogie and the tramcar which are provided by the invention, through the arrangement of the anti-twisting devices at the two ends of the bogie framework, the bogie has good guidance quality in the running process of the tramcar, the peak of force applied by each wheel to a rail can be greatly reduced, wear of a rim of each wheel on a curve track, which is caused by the case that the wheel is close to the steel rail, is reduced, the service life of the tramcar is prolonged, and meanwhile the tramcar has an automatic resetting and centring function, so that the tramcar has good comfort.
Description
Technical field
The present invention relates to track train field, relate in particular to the non-power truck of a kind of 100% low floor tramway train and tramway train.
Background technology
Nineteen ninety, first 100% low floor tramway train formally exposes at Bremen, Germany in the world, and from then on, urban tram entered into for 100% low floor epoch.The floor level of 100% low floor tramway train is generally 350mm left and right, facilitates passenger, especially getting on or off the bus of children, wheelchair-bound disabled person etc.Meanwhile, facilitate passenger to move in car, reduce the time of getting on or off the bus.According to foreign statistic, compared with common light rail car, low floor vehicle passenger getting on/off time decreased 30%.Can meet the freight volume demand of different cities and circuit by adjusting the organizational systems of train.
Bogie truck, as the running gear of tramway train, is the critical component of its operation, guiding, load-carrying and vibration damping.Riding quality, safety and the economy of bogie truck and tramway train have substantial connection.Use traditional axletree cannot meet floor requirement for height, need to replace with axle bridge, remove the rotation coupling of left and right wheels completely, taken turns changing a pair of independent wheel into by tradition.Double-row conical bearing supporting wheel is used respectively at axle bridge two ends.Transmission and brake component are arranged in lateral wheel, the independent transmission of each wheel or braking.Attainable floor level only depends on that axle bridge is apart from the height and of rail level, the amount of deflection of secondary spring.Independent wheel can significantly reduce height of floor from rail top, does not produce snakelike unstable phenomenon, improves the critical speed of Vehicular system.But the steering capability of independent wheel is poor, the wheel rim rail that reclines on curve circuit, can not automatic centering on straight line circuit, easily causes flange wear, shortens wheel to service life.
Summary of the invention
The object of the present invention is to provide the non-power truck of a kind of 100% low floor tramway train and tramway train, solve mechanism of independent wheel in the non-power truck of existing 100% low floor tramway train poor to steering capability, on curve circuit, wheel rim easily reclines rail and causes the problem of wearing and tearing.
To achieve these goals, the invention provides the non-power truck of a kind of 100% low floor tramway train, comprise truck frame, the rear and front end of described truck frame is provided with anti-winding device, in order to regulate the relative position between described truck frame and car body.
The present invention also provides a kind of tramway train on the other hand, and this tramway train includes the non-power truck of 100% low floor tramway train as above.
The non-power truck of 100% low floor tramway train provided by the invention and tramway train, by anti-winding device being set at the two ends of truck frame, vehicle is in operational process, bogie truck has good guidance quality, can significantly reduce the wheel effect peak value of power in orbit, reduce the wearing and tearing that rail causes that recline of the wheel rim of wheel on curve circuit, increase the service life of wheel, vehicle has the alignment function of automatically reseting simultaneously, thereby train has good traveling comfort.
