Description
Technical field
The present invention relates to magnetic-levitation train technical field, particularly a kind of braking technology of magnetic-levitation train.
Background technology
Relative to wheel-rail train, the remarkable advantage of magnetic-levitation train is that the contact movement between parts is few, avoids machinery
Abrasion and later maintenance, such as with linear motor instead of electric rotating machine, Wheel Rail Contact is changed to suspend.But the machinery of magnetic-levitation train
Mode of braking has still followed traditional hydraulic tongs mode of braking, and hydraulic tongs are made of hydraulic cylinder, caliper etc., this covering device is not
Only movable part is more and occupied space.Magnetic-levitation train falls vehicle mode of braking in crisis, but does not follow this thinking research
Go down, but gone on along hydraulic tongs mode of braking.
Wheel track braking process is the rotating speed of brake wheel, this stage is rolling friction, and friction coefficient is small, frictional force is small；So
Rear wheel is no longer rotated by locking, is slided under effect of inertia until stopping, this stage is sliding friction, and friction coefficient is big, rubs
It is big to wipe power.The brake silpper of the present invention has supporting role concurrently, and rail process is controllably sat using magnetic-levitation train and realizes sliding friction braking,
Wheeled vehicle, which is limited to structure, can not possibly seat rail braking.It is mounted on to brake silpper visible seam contact pin type on magnetic-levitation train and is formed greatly
Contact area reduce pressure, reduce abrasion, the hydraulic tongs installation space of saving can be used for installation electromagnet or linear motor to carry
High suspension force or tractive force.
Invention content
The object of the present invention is to provide a kind of slipper brakes of magnetic-levitation train, it can efficiently solve existing magnetic-levitation train
The problem of brake structural complexity and big occupied space.
The technical solution adopted in the present invention is：A kind of slipper brake of magnetic-levitation train, including circuit sleeper and suspension
Frame, circuit sleeper both sides are equipped with cantilevered magnetic conduction rail, and the cross section of suspension rack is closed for top and both sides three side sealing, in bottom
Section opening and both sides carry the semi-closed structure of cantilever, the upper surface of two bottom sides cantilever and the lower section for being located at magnetic conduction rail distal end
Equipped with electromagnet, the inner surface of suspension rack top both sides and positioned at magnetic conduction rail proximal end top equipped with rubber pad, brake silpper leads to
Cross the Interal fixation of bolt and rubber pad lower surface.
The upper and lower surface of rubber pad is equipped with steel plate, which is fixed by compression molding technique with rubber pad.
The inner surface at the top of steel plate and suspension rack that the rubber pad passes through upper surface is fixed.
The material hardness of the brake silpper is less than magnetic conduction rail material hardness.
The beneficial effects of the invention are as follows：Replace hydraulic tongs that can save installation space, reduction mechanical wear with brake silpper.Rubber
The stress of the rubber cushion meeting each brake silpper of autobalance simultaneously reduces vertical vibration, makes each brake silpper that can uniformly share and rubs
Wipe power.

Specific embodiment
In order to further appreciate that present disclosure, feature and effect, following embodiment is hereby enumerated, and coordinate attached drawing detailed
It is described as follows：
Embodiment, as shown in Figure 1, a kind of slipper brake of magnetic-levitation train, including circuit sleeper 1 and suspension rack 6, circuit
1 both sides of sleeper are equipped with cantilevered magnetic conduction rail 3, and the cross section of suspension rack 6 is closed for top and both sides three side sealing, and bottom stage casing is opened
Mouthful and both sides carry the semi-closed structure of cantilever, the upper surface of two bottom sides cantilever and set below 3 distal end of magnetic conduction rail
There is an electromagnet 2, the inner surface of 6 top both sides of suspension rack and rubber pad 4, brake silpper 5 are equipped with above 3 proximal end of magnetic conduction rail
Pass through bolt and the Interal fixation of 4 lower surface of rubber pad.
The 4 upper and lower surface of rubber pad is equipped with steel plate, which is fixed by compression molding technique with rubber pad.
The rubber pad 4 is fixed by the steel plate and the inner surface at 6 top of suspension rack of upper surface.
The material hardness of the brake silpper 5 is less than 3 material hardness of magnetic conduction rail.
During train operation, magnetic-levitation train is in suspended state, has between 5 bottom of brake silpper and magnetic conduction rail 3 between suspension
Gap.During train braking, 5 bottom of brake silpper is contacted with 3 upper surface of magnetic conduction rail, and train braking is realized by frictional force.
As shown in Fig. 2, in suspended state the imperceptible impact of passenger is allowed to gradual braking, the suspension that electromagnet 2 provides
Power cannot cancel at once but gradually revocation, therefore the normal pressure that brake silpper 5 is subject to gradually rises to car weight, with magnetic conduction steel
The frictional force that rail 3 generates becomes larger.Under emergency braking operating mode, suspending power is cancelled at once, rail braking is directly sat by magnetic-levitation train.
The dynamics calculation effect of the present invention is satisfied, such as railway carriage weighs 36 tons, speed 200km/h, with the overload of occupant comfort such as
0.13G implements braking, and more than 1200 meters of braking distance, duration 44.5 seconds are suitable with wheel-rail train.
