Embodiment Construction

[0032] The present invention will be further described below in conjunction with the embodiments and accompanying drawings, but the present invention is not limited thereto.

[0033] The train energy feedback type active radial bogie (hereinafter referred to as the bogie) provided by the present invention has a structure such as figure 1 As shown, it consists of three major systems: energy recovery system, active control system and radial steering system. Wherein: the energy recovery system can recover the energy of the vertical vibration of the train in the form of electric energy, store it in the storage battery, and provide electric energy for the active radial steering of the present invention. The active control system establishes the actual track path input and body attitude information feedback by collecting vehicle speed information, and drives the servo motor to rotate through the control of the central processing unit, so that the articulated swing arm mechanism of t...

Abstract

The invention discloses a train energy feedback type active radial bogie. The train energy feedback type active radial bogie is provided with an energy recovery system, an active control system and a radial steering system. The radial steering system comprises a front swing arm assembly, a rear swing arm assembly and a radial steering transmission device. The front swing arm assembly and the rear swing arm assembly are connected with a gear base of an upper bevel gear (11) and a gear base of a lower bevel gear (12) through flanges respectively, wherein the upper bevel gear (11) and the lower bevel gear (12) are arranged on the radial steering transmission device. The train energy feedback type active radial bogie has the advantages of being simple in mechanical structure, moderate in cost and capable of achieving energy recovery, being used for assembling rail train radial steering equipment replacement parts, and having the good radial steering effect.

Description

technical field [0001] The invention relates to a bogie, in particular to an energy feedback type active radial bogie for rail trains. Background technique [0002] Existing trains will cause huge dust pollution and economic losses due to wheel and rail wear, and the radial steering technology of trains is the main technical solution to reduce wheel and rail wear. [0003] The radial steering of the train wheel set is mainly realized by the radial bogie, and the radial bogie is mainly divided into three types: self-guiding, forced-guiding and active radial steering. [0004] The self-steering radial bogie drives the wheel set to move in the radial direction by itself through the force between the wheel and the track. This solution is low in cost and does not require additional energy consumption, but the curve passability is poor and the radial degree of the wheel set is low. [0005] The forced-guided radial bogie relies on the mechanism connected to the car body to force ...
