6. two of bogie truck wheels vertically link to each other with framework (2) by pivoted arm location rubber arthrosis (13) to axle box (1).
The single stage suspension vertical stiffness is mainly provided by helical steel springs, and pivoted arm rubber arthrosis rotational stiffness proportion in the single stage suspension vertical stiffness is very little.This version is easier to realize single stage suspension three-way rigidity rational Match, helps the bogie truck high-speed cruising.It realizes traction and braking, and the supporting locomotive weight is realized the locomotive guiding, and accommodation curve passes through, and adapts to the lateral stability of locomotive.
The utility model A type metro vehicle bogie framework adopts by high-quality steel all welded constructions such as high strength low alloy steel plate, steel pipe, foundry goods.Main transmitting tractive of framework and braking force, supporting body weight, each parts of installing and locating bogie truck, and bear from wheel to the vibratory impulse of car body, hang traction electric machine, drg, actuating device, auxiliary device and also transmit the motive power that these parts produce.Framework in the utility model is in light weight, the intensity height.
A type metro vehicle bogie draw gear of the present utility model adopts simplex pull rod push-pull type structure, it is simple in structure, can vertically realize the transmission of tractive force, braking force, and can realize laterally, catenary motion and rotation, can better adapt to the various motions between bogie truck and car body.
A type metro vehicle bogie foundation brake rigging of the present utility model adopts the Multiple disc brake mode, to satisfy railcar high speed deceleration and stopping performance.
A type metro vehicle bogie actuating device of the present utility model adopts denture clutch, integral traction alternating current dynamo, half suspended load formula gear box structure.
Among the utility model embodiment, two wheels of bogie truck vertically link to each other with framework (2) by pivoted arm location rubber arthrosis (13) to axle box (1).Be implemented in the location on the bogie truck, and make wheel to can realizing that at orbit plane low-angle relatively rotates with respect to framework, laterally and vertical by one be steel spring group (14) realize wheel to the location of framework.This takes turns linear running stability and the curving performance that locate mode has been guaranteed this programme A type metro bogie.
A type metro bogie of the present utility model has good horizontal traveling comfort and high-speed cruising stability, and the highest overall trip speed is 100km/h.
Adopt the railcar of the A type metro bogie of 100km/h speed class of the present utility model to have vast market prospect in the big city field of track traffic.
