Description

technical field [0001] The invention belongs to the field of rail vehicle motor suspension devices, and in particular relates to a shock-absorbing axle seat device for motor suspension. Background technique [0002] The rail train based on the linear motor as the driving device changes the power of the vehicle from the rotational adhesion drive to the motor linear drive, which improves the climbing ability of the rail vehicle and greatly improves the vehicle's ability to adapt to the terrain. The special rail for the linear motor of this type of train is provided with an induction plate, and a small enough air gap must be kept between the linear motor and the induction plate to improve the driving force of the linear motor. This type of rail vehicle not only inherits the technical advantages of the conventional steel wheel-rail rail transit system, but also avoids the technical weaknesses of rubber wheel monorail and other transportation systems, so it can be widely used in ...

Problems solved by technology

[0006] In order to solve the problem that the existing shaft-suspended motor suspension method in which the linear motor is directly hung on the axle of the train will constrain the freedom of movement of the bogie wheel to the axle, the vibration of both the frame and the axle will act directly in the form of rigid transmission. On the linear motor, which affects the service life of the three; and the suspension structure of the linear motor with elastic shock absorption function is to suspend the linear motor on the frame beam through a series of springs, and only through a series of springs with a large length In order to hang down from the frame beam for a long enough distance, so that the air gap value between the linear motor suspended by the primary spring and the induction plate on its special rail is within the parameter range specified by the design, but the length value is relatively large The first series of springs weakens the stiffness parameter of the spring against its own radial swing, resulting in a greater swing degree of freedom for the linear motor suspended by the first series of springs, thereby increasing the swing and vibration amplitude of the linear motor and reducing the linear motor. The stability and reliability of the installation will further shorten the maintenance period and increase the inspection frequency, increase the maintenance cost, and negatively affect the safety of train operation.
