Although this kind of brake disc can improve the convective heat dissipation effect of the brake disc and reduce the temperature rise of the brake disc under the braking condition of the train, it will greatly consume the traction of the train due to the pumping effect under the traction condition. power
At present, there is no device that can actively control the pumping effect of the brake disc, so that on the one hand, the convective heat dissipation effect of the brake disc can be maintained, and on the other hand, the power consumption of the pumping air of the brake disc when the train is towed can be reduced

An active control device for reducing air pumping power consumption of the brake disc of a high speed train comprises a linear bearing element, a double tapered roller bearing element, a brake disc air inlet opening / blocking element and a driving cylinder, wherein the brake disc air inlet opening / blocking element and the linear bearing element as well as the double tapered roller bearing element and the driving cylinder are connected and matched to achieve the purposes of rectilinear motion in the axial direction of an axle and synchronous rotation along with the axle. Through the combination between the double tapered roller bearing element and the linear bearing element, the active control device is a floating active control device which integrates the rectilinear motion and the rotational motion and reduces the power consumption, the air pumping power consumption of the brake disc is reduced under the traction condition of the train through controlling the opening / blocking of the air inlet of the brake disc by a rubber element, and the convection heat dissipation effect of the brake disc is maintained under the brake condition of the train.
Description
technical field [0001] The invention belongs to the technical field of railway vehicles, and relates to an active control device for reducing power consumption of train brake disc pumps, in particular to a floating active control device for reducing power consumption that integrates rotary motion and linear motion. technical background [0002] Most of the high-speed trains currently operating online, especially those in China, use ventilated brake discs with internal cooling ribs. Although this kind of brake disc can improve the convective heat dissipation effect of the brake disc and reduce the temperature rise of the brake disc under the braking condition of the train, it will greatly consume the traction of the train due to the pumping effect under the traction condition. power. At present, there is no device that can actively control the air pumping effect of the brake disc, so that on the one hand, the convective heat dissipation effect of the brake disc can be mainta...
