Problems solved by technology

To achieve this relative movement (rail, bogie, car body) must solve the following problems: 1) The bogie must fit the track to obtain the maximum suspension force and maintain the direction of motion; 2) The bogie and the car must maintain a certain relative Positional relationship to prevent unbalanced load; 3) The bogie needs to drive the car body to deflect and change the direction of motion, so there must be a connection point between the bogie and the car body, and this connection cannot limit the freedom of the bogie to run along the track
[0014] 1. When the train passes the curved track, the two displacements produced by the air spring must be compensated, and the trajectory is not the real trajectory of the end, which is prone to additional vibration;
[0015] 2. Generate additional force, affecting the flexibility of bogie rotation;
[0016] 3. Lead to complex mechanism, increase manufacturing and maintenance costs

Abstract

The invention provides a magnetic levitation steering mechanism which is installed between a vehicle body and a steering frame of a magnetic levitation vehicle, and the steering mechanism is an arc movable sliding table, wherein the upper part of the sliding table is connected with the vehicle body, and the lower part of the sliding table is connected with the steering frame; the upper part and the lower part of the sliding table make relative movement with a circular arc movement trail. The introduction of the magnetic levitation steering mechanism realizes that a moving point of a steering module forming the steering frame makes arc movement around a relative rest point to drive the vehicle body and the steering frame to make circular arc relative movement together, so that the vehicle passes through a curve track smoothly, and the service life of an air spring and the steering frame is prolonged.

Description

Technical field [0001] The present invention relates to the technical field of magnetic levitation vehicles, in particular, to a magnetic levitation steering mechanism for magnetic levitation trains. Background technique [0002] Magnetic levitation train is a kind of train driven by magnetic levitation force (that is, magnetic attraction or repulsion). Because the magnetic force of the track makes it levitate in the air and does not need to touch the ground when walking, its resistance is only air resistance. The maximum speed of the maglev train can reach more than 500 kilometers per hour, with high speed, low noise, environmental protection, economy and comfort Features. [0003] Reference Figure 1-A The structure diagram of the magnetic levitation train steering device shown and Figure 1-B Shown Figure 1-A The enlarged view of the middle part M and the schematic diagram of the force. The bogie 11 is installed on the rail 14, an air spring 12 is provided on the bogie 11, and ...
