Description
Technical field
The present invention relates to a kind of suspension gear of guideway vehicle linear electric machine.
Background technology
The operation of electric track vehicle relies on the driving of motor, and traditional rotating machine mainly is made up of stator and rotor, when being advanced by its rotor driven wheel, needs with a cover complicated mechanical driving system.A kind of later-model guideway vehicle type of drive adopts linear electric machine, and it is that stator with motor is launched into plane (straight line) and is suspended on the vehicle bottom, and its rotor then is the pole plate of laying on the ground between two tracks (also claiming reaction rail).Because linear electric machine all parts except that rotor (ground pole plate) all are installed on the motor stator, so also often the stator of linear electric machine directly is called linear electric machine.The linear electric machine of mentioning below the patent specification also is meant the linear electric machine stator usually.After the energising, between linear electric machine and ground pole plate (rotor), produce magnetic force, promote the guideway vehicle operation.Gap between linear electric machine and the ground pole plate also is the size of air gap and stable, is directly connected to the drawbar efficiency of guideway vehicle such as train and the stability of operation.Existing linear electric motor device adopts passive direct suspension method, is suspended on usually on the truck frame of vehicle or on the wheel shaft, just proposes linear electric machine is suspended on the wheel shaft of train as China Patent No. CN85108129A.
There are 4 deficiencies in prior art: the one, be subjected to truck frame and wheel to etc. a series of suspensions influence, and wheel track between the influence of factors such as mutual action, ground pole plate and rail the relative position error, cause size of gaps to have bigger variation, cause the magnetic force instability that promotes vehicle operating with vehicle operating.The 2nd, have in size of gaps under the situation of bigger variation, for guarantee the high-speed cruising vehicle safely, avoid linear electric machine and the collision of ground pole plate, air gap must be provided with quite big, usually be set to 10-12mm, and the stator of common motor and the air gap between rotor only are 2～3mm, the obvious increase of air gap causes seriously undermining of magnetic field, and electrical efficiency is reduced greatly.The 3rd, smaller and stable for guaranteeing the air gap between linear electric machine and ground pole plate, the discrepancy in elevation between just necessary strict control pole plate and rail, this mounting process to linear electric machine and ground pole plate requires very strict, and its work difficulty and cost all will increase greatly.The 4th, the linear electric machine quality is big, directly be suspended on the wheel shaft, will increase weight or unsprung weight between the spring of vehicle greatly, the live load that causes being born between bogie truck and the wheel track has remarkable increase, reduce the damping performance of vehicle, strengthen the wearing and tearing of bogie truck, wheel track.
Summary of the invention
Purpose of the present invention just provides a kind of guideway vehicle linear electric machine driving hanger, and this kind device can make that the air gap of linear electric machine and ground pole plate is little and reliable and stable, electrical efficiency is high; The live load of bearing between bogie truck and the wheel track is low, wearing and tearing are little, and the damping performance of vehicle is good; And installation requirement is low, cost of installation is few.
The present invention solves its technical matters, the technical scheme that is adopted is: a kind of guideway vehicle linear electric machine driving hanger, contain the linear electric machine that hangs under car body, the car body, the ground pole plate that ground two interorbitals are laid, its constructional feature is: linear electric machine hangs on the car body bottom through servoactuator; Servoactuator electrically connects through control cable and suspension controller; The non-contact displacement transducer of measuring linear electric machine and pole plate gap, ground is installed on the body of linear electric machine, and this sensor also electrically connects through cable and suspension controller.
Compared with prior art, the invention has the beneficial effects as follows: because linear electric machine hangs on the car body bottom through servoactuator, and the expansion link of servoactuator can be subjected to artificial or automatic control device control is carried out accurately flexible, thereby when vehicle operating, spacing according to linear electric machine and ground pole plate also is the situation of change of air gap, it is upper and lower mobile to regulate size of gaps to drive linear electric machine by servoactuator at any time, guarantees that air gap is little and is stabilized in setting value, the electrical efficiency height; Because size of gaps can conveniently regulate, also just need not strict control ground pole plate and rail between the discrepancy in elevation, so the mounting process of its linear electric machine and ground pole plate require low, install easy, cost is low.And because linear electric machine hangs on the car body bottom on the spring, but not between spring, under the spring on position such as the axletree, thereby greatly reducing weight or unsprung weight between the spring of vehicle, vehicle damping is good, and reduced the live load of bearing between bogie truck and wheel track, reduce its wearing and tearing.
Because servoactuator electrically connects through control cable and suspension controller.Moved by suspension controller control and driving servoactuator like this, and it is upper and lower mobile to drive linear electric machine, realizes the control to linear electric machine and ground pole plate air gap value, its control is more accurate, reliable.
Because the non-contact displacement transducer of measuring linear electric machine and pole plate gap, ground is installed on the body of linear electric machine, this sensor also electrically connects through cable and suspension controller.Like this by displacement pickup with the air gap situation of change, respond to exactly in real time, and send suspension controller to, suspension controller timely control servoactuator more accurate in view of the above, that do not have hysteresis moves, thereby more constant, failure-free control that the air gap value can obtain, and make the overall process of air gap control realize automation.
Above-mentioned linear electric machine is provided with the stop gear that limits the upper and lower mobile maximum position of linear electric machine.
The limited post that consists of of above-mentioned stop gear is fixed in linear electric machine top, and the spacing hole on this limited post top is sleeved on the right wheel shaft of car body steering framing wheel.
Because the numerical value of setting is pressed greater than the axletree diameter in the spacing hole aperture, so limited post and linear electric machine thereof can and can only be upper and lower mobile in this spacing hole's restricted portion, thereby guarantee that linear electric machine active (servo) is hung just in case after losing efficacy, mechanically limit the upper and lower mobile end position of linear electric machine, vehicle still can continue low cruise, and can keep in repair in having the station of maintainability; And avoid the vehicle paralysis on the way can't advance, and also be difficult to the difficulty of keeping in repair.
The quantity of above-mentioned servoactuator is one, two, three or four.
