Abstract

The present invention relates to an overlapping device for a running mechanism of a low speed magnetic suspension train, which is formed from that a pair of upper supporting seats (3a) and a pair of lower supporting seats (3b) are respectively fixed at the upper parts and the lower parts in two corresponding modules (1) of a running mechanism. An upper supporting seat (3a) and a lower supporting seat (3b) of the same module (1) are interlaced in a front position and a rear position, an upper supporting seat (3a) of one module (1) and a lower supporting seat (3b) of the other module (1) are the same in the front position and the rear position. A connecting shaft (4) is connected between two supporting seats of the same pair of upper supporting seats (3a) or the same pair of lower supporting seats (3b). A hanging ear (5) is connected between the connecting shafts (4) of the upper supporting seats (3a) and the lower supporting seats (3b). The overlapping device can cause a module generating faults not to fall on a rail during running of a train, meanwhile, the transverse dislocation and the longitudinal displacement of two adjacent modules during normal running of the train can not be influenced.

Description

The lapping device that is used for low speed magnetic suspension train running mechanism

Technical field

The invention belongs to the magnetic suspension train technical field, belong to the running mechanism technical field of low speed magnetic suspension train especially.

Background technology

The running mechanism of low speed magnetic suspension train is made up of module (normally 5 pairs), and body suspension is on running module.When operation, by electromagnetic attraction module is suspended in orbit, each module is controlled separately.In travelling, when electric (or other reason) fault occurring, if a module can not suspend, remaining module just often, this malfunctioning module will drop on the track and track friction, collision, cause the accident.At present, still incompetent malfunctioning module do not come off in orbit mechanism or the device of making in low speed magnetic suspension train.

Summary of the invention

Purpose of the present invention just provides a kind of lapping device that is used for low speed magnetic suspension train running mechanism, and this kind lapping device can make train under steam, and the module of et out of order does not drop on the track; Simultaneously, it does not influence the transversion malposition and the longitudinal travel of train two adjacent blocks in cruising.

The technical solution adopted for the present invention to solve the technical problems is: a kind of lapping device that is used for low speed magnetic suspension train running mechanism, it consists of: the upper and lower of the two relative module inboards of running mechanism is fixed with upper and lower two pairs of bearings respectively, and the upper bracket and the undersetting of same module misplace on front and back position; The upper bracket of one module then with the undersetting front and back position of another module on identical; Be connected with adapter shaft between two bearings of same pair of upper bracket or same pair of undersetting, be connected with hanger between the adapter shaft of the upper bracket of a module and the undersetting of another module.

Working process of the present invention with principle is: the upper bracket of a module couples together two relative modules with the undersetting of another module by hanger, forms the connection mode of intersecting in twos.When wherein a module et out of order falls, because the undersetting of this malfunctioning module links to each other with the upper bracket of another normal module by hanger, thereby normal module is upwards held this malfunctioning module bearing by this, make malfunctioning module not drop on the track, and not can with orbiting collision, friction, have an accident, the fault train can walk on and overhaul to the maintenance point.And because the inside upper part and the bottom of two relative modules are provided with two pairs of bearings respectively, and the upper and lower bearing of same module is gone up dislocation at front and back position (on This train is bound for XXX), the two ends of hanger are separately fixed on the undersetting of another module of module upper bracket by adapter shaft, form a kind of connection of swinging, adapter shaft can vertically move, radially wobble around hanger and certain transversion malposition.Also promptly two adjacent modules can vertically reach transversion malposition, and intervention module is not passed through curve track.Make and catenary motion and cross motion decoupling zero do not retrain cross travel and longitudinal travel that train produces in cruising.

The present invention adopts the beneficial effect of above invention scheme to be, when the train et out of order, malfunctioning module will be held by another relative module, and not drop on the track, avoid the generation of accident, guarantee the safety of train operation; Simultaneously, it does not influence the transversion malposition and the longitudinal travel of train two adjacent blocks in cruising yet.

The concrete structure that is connected hanger between the adapter shaft of the upper bracket of one module and the undersetting of another module is: the middle part of adapter shaft is through on the through hole of hanger end, is embedded with rubber arthrosis between through hole and the adapter shaft.

What rubber arthrosis between hanger and the adapter shaft formed flexibly connects, and has both guaranteed that hanger can be around the flexible swing of adapter shaft, module vertical, transversely for flexibly connecting, make horizontal, the longitudinal travel of train when cruising not be subjected to rigid constraint; Make the impact and the collision that do not produce rigidity between hanger and the adapter shaft again, improved reliability of the present invention and service life.

Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.

The specific embodiment

Fig. 1-4 illustrates, and a kind of specific embodiment of the present invention is; A kind of lapping device that is used for the low speed magnetic suspension train running module, it consists of: relative two modules, 1 inboard (i.e. the opposite face of two modules) of running mechanism, the upper and lower be fixed with upper and lower two pairs of

bearing

3a, 3b respectively, the upper bracket 3a and the undersetting 3b of same module 1 misplace on front and back position, if also be the front portion of upper bracket 3a in module 1, the undersetting 3b of same module 1 is then at the rear portion of this module 1; On the contrary, if undersetting 3b forwardly, then upper bracket 3a is at the rear portion.The upper bracket 3a of the one module 1 then undersetting 3b with another module 1 is identical on front and back position; Be connected with between two bearings of same pair of upper bracket 3a or same pair of undersetting 3b between the adapter shaft 4 of undersetting 3b of the upper bracket 3a of adapter shaft 4, one modules 1 and another module 1 and be connected with hanger 5.

Fig. 3 illustrates, and the concrete structure that is connected hanger 5 between the adapter shaft 4 of the upper bracket 3a of a module 1 and the undersetting 3b of another module 1 is: the middle part of adapter shaft 4 is through on the through hole of hanger 5 ends.The external diameter that is embedded with rubber arthrosis 6 between through hole and the adapter shaft 4 and is rubber arthrosis 6 cooperates with the through hole of hanger 5 ends, and the internal diameter of rubber arthrosis 6 cooperates with the external diameter at adapter shaft 4 middle parts.
