Abstract

The invention discloses a bullet train bogie which comprises a frame (A), an axle system (K) arranged on the frame (A), a gear box (M) and a traction motor (L) which are used for driving the axle system (K) to move, a wheel disc brake device (H) and an air spring (B) arranged on the frame (A). The frame comprises a beam (4), a lateral beam (1) and a vertical beam (5). An air spring installation seat (11) is arranged on the lateral beam (1), the air spring (B) is arranged on the air spring installation seat (11), the lateral beam (1) is a hollow lateral beam with an inner cavity, and an additional air chamber (12) communicated with the air spring is formed in the inner cavity. Due to the fact that the lateral beam is arranged to be the hollow lateral beam, the additional air chamber communicated with the air spring is formed in the inner cavity, the air chamber volume is increased, the rigidity of the air spring is reduced, a damping effect is improved, and a vibration reduction effect is improved.

Description

technical field [0001] The invention relates to the technical field of EMU equipment, in particular to an EMU bogie. Background technique [0002] At present, damping springs are installed on the bogies of EMUs to reduce the vibration between the wheels and the carriages and improve ride comfort. The main type of vibration damping spring is air spring, which is widely used due to its short filling time and good vibration damping effect. [0003] However, due to the large number of parts on the bogie, the installation position of the air spring is limited, thereby limiting the air volume of the air spring, so that the air spring has a low damping effect on the wheel and the carriage. [0004] Therefore, how to improve the vibration damping effect is an urgent problem to be solved by those skilled in the art. Contents of the invention [0005] In view of this, the present invention provides a motor vehicle bogie to improve the vibration reduction effect. [0006] To achie...
