Problems solved by technology

[0003] However, the steering force provided by the traditional bogie is not enough to alleviate the excessive centrifugal force and guiding gravity generated between the wheel and the track, so that the friction between the wheel flange and the side track surface produces high levels of noise and vibration, thus compromising the driving comfort of the passengers
The problem also leads to wheel wear and track damage, allowing serious accidents such as derailment of rail vehicles

Abstract

An active steering bogie for railway vehicles can improve the driving stability of a railway vehicle running at a high speed, thereby increasing the stability of the vehicle, so that the vehicle is not derailed, and can also minimize the vibration of wheels and rails during the driving of the vehicle, thereby ensuring driving comfort. The active steering bogie uses leverage, has a simple structure of links for steering wheel shafts of the bogie, and can use leverage to actuate the links with a small force, thereby reducing the weight of the bogie and facilitating maintenance. The active steering bogie includes a front steering unit, hinged to front axle boxes on both sides of a front wheel shaft to steer the front wheel shaft; and a rear steering unit, hinged to rear axle boxes on both sides of a rear wheel shaft to steer the rear wheel shaft.

Description

technical field [0001] The invention relates to an active steering bogie for a railway vehicle, which can improve the driving stability of a railway vehicle running at high speed, thereby enhancing the stability of the railway vehicle, preventing the railway vehicle from derailing, and reducing the Vibration of wheels and rails during vehicle running, thereby ensuring driving comfort. More particularly, the present invention relates to a leveraged active steerable bogie for a railway vehicle, in which a simple linkage structure is used to steer the axle of the bogie and the bogie can drive the axle with a small amount of force using leverage. link, which significantly reduces the weight of the bogie and facilitates maintenance. Background technique [0002] Generally, a bogie used in a railway vehicle can support the weight of the vehicle body in such a way that the weight of the vehicle body is equally distributed to each wheel, and can also freely turn relative to the veh...
