Description

Special linear motor hanging seat for rail train

Technical Field

The utility model belongs to rail vehicle motor linkage field, concretely relates to special linear electric motor of rail train hangs seat.

Background

The rail train based on the linear motor as the driving device changes the power of vehicle operation from rotary adhesion driving into motor linear driving, thereby improving the climbing capability of the rail train and greatly improving the adaptability of the vehicle to terrain. The induction plate is arranged on the special rail for the linear motor of the train, and a small enough air gap must be kept between the linear motor and the induction plate so as to improve the driving force of the linear motor. The rail vehicle type has the technical advantages of the conventional steel wheel-steel rail traffic system, and can avoid the technical weaknesses of traffic systems such as rubber wheel single rail and the like, so that the rail vehicle type can be widely applied to various urban rail traffic lines with complex terrain.

The existing linear motor is connected with a bogie frame of a rail train through a hanging seat type suspension device, and the main connection mode comprises the following two modes:

the axle suspension type motor suspension mode is that a linear motor is directly suspended on an axle of a train through a fixed hanging seat, but the suspension structure can restrict the freedom degree of movement of a steering bogie wheel to the axle, the vibration of a framework or the vibration of the axle are directly acted on the linear motor in a rigid transmission mode, and the vibration of the framework or the axle interferes with the vibration of the linear motor, the framework and the axle, so that the service life of the linear motor, the framework and the axle is influenced.

Another linear motor suspension structure with elastic damping function is to suspend the linear motor on the frame beam through a series of springs, but because the distance between the frame beam and the rail dedicated to the linear motor is large, a series of springs with a large length value are required to suspend downward from the frame beam for a long enough distance, so that the air gap value between the linear motor suspended by the series of springs and the induction plate on the rail dedicated to the linear motor is within the design parameter range. However, the primary spring with a large length value meets the length requirement, and simultaneously, the stiffness parameter of the spring for resisting self radial swing is inevitably weakened correspondingly, so that the linear motor suspended by the primary spring has a larger swing freedom degree, the swing and vibration amplitudes of the linear motor are increased, the stability and reliability of the installation of the linear motor are reduced, the shortening of the overhaul period and the improvement of the inspection frequency are further brought, the maintenance cost is increased, and the safety of train operation is negatively influenced.
