The size of brake(-holder) block should match with brake, while mutually fit with maximum braking friction needed for braking again
It answers.Therefore, the drag friction chip size on existing rail traffic vehicles is generally large.When driver brakes vehicle, lead to
It crosses brake handle or pedal control braking system generates a pressing force to frictional force, although theoretically, brake handle or stepping on
Plate, which can control braking friction, starts from scratch and is gradually increased, but due to inaccurate and braking system the manipulation of control of people
There are resistances such as frictional force in mechanism, pressure needs to reach a certain lower limit value, brake could be driven to generate pressure to friction plate
Clamp force.So, when driver's abrupt deceleration vehicle, by the brake force that braking system generates being opened by zero in actual mechanical process
What the beginning was gradually increased, it is possible to which the brake force that the slight moving handle of driver or pedal generate in braking system is still above required
Brake force, when vehicle being made to enter on-position, generate apparent impact, influence the comfort of passenger.Especially for carrying
Biggish vehicle is measured, the size of brake(-holder) block is bigger, when vehicle enters on-position, since the inertia of vehicle is bigger, braking
The impact that moment generates will be bigger, influence on the comfort of passenger also bigger.

Power.
As illustrated in figs. 2 through 8, the side of brake disc 3 is equipped with multiple fixed blocks 9, and all fixed blocks 9 are connected by limiting bracket 10
It is connected in an entirety, and is fixedly connected by limiting bracket 10 with vehicle.Friction plate 4 is slidably arranged in fixed block 9 and limit
The inside of position bracket 10.Specifically, there is the guide groove 91 perpendicular to 3 friction surface of brake disc, respectively on the inner sidewall of each fixed block 9
It is respectively equipped with a guiding projection 41 on the both ends side wall of friction plate 4, each guiding projection 41 is respectively with corresponding guide groove 91 along vertical
It is slidably matched in the direction of 3 friction surface of brake disc.
Working principle:
Such as Fig. 4, friction plate group forms the circular circumference for covering entire brake disc 3, more friction plates 4 and brake disc 3
Surface contact, makes the surface of brake disc 3 be fully used, when the peak value oil pressure in brake piston cylinder 5 is identical, all frictions
Piece 4 works together, can generate bigger brake force, and bigger peak value brake force is provided for vehicle；If peak needed for vehicle
Value brake force remains unchanged, then increasing due to 4 quantity of friction plate of participation braking, required peak value in each brake piston cylinder 5
Oil pressure is smaller, reduces the sealing intensity requirement of braking system oil sealing everywhere, reduces costs.
When more friction plates 4 participate in, the size of each friction plate 4 can be smaller；Existing friction plate is minimized, by
The ipsilateral single plate friction piece of brake disc before becomes multiple-piece friction plate.In multiple-piece friction plate, each friction plate is connect
Touching friction area is respectively less than the contact friction area of existing single plate friction piece.When starting braking, the 1st friction plate 4 intervenes institute
The braking impact of generation is smaller；When each friction plate 4 is successively intervened, the amount of rising to of brake force is smaller, reduces braking impact；As
A kind of preferably since friction plate 4 is more, the size of friction plate 4 can be different, brake just section and middle section when vehicle is in
When, it is intervened by smaller friction plate, makes to brake just section and brake force variation in middle section is gentler, braking impact is smaller, works as vehicle
When in braking back segment, required brake force is larger, and larger sized friction plate 4 can be allowed to intervene, realize faster brake force
It rises to and stronger brake force exports.It is higher due in vehicle travel process, braking just section and middle section frequency of use, therefore both
It can be improved braking comfort, and can guarantee the braking safety under the extreme case that vehicle needs bigger brake force.
When the friction plate 4 of identical size is distributed in brake disc surface, each brake pressure control valve 6 is controlled using motor 7
The compression elasticity of interior compressed spring 67 controls the different interventions of friction plate 4 or intervenes each friction plate 4 in each braking
Order it is different, make the uniform abrasion of each friction plate 4, extend the service life of each friction plate 4, reduce maintenance times and at
This.
As a preference, each motor 7 and the electrical connection of controller (not shown), are set by controller
The each motor 7 of process control works.
In the present invention, every group of friction plate 4 is individually controlled by independent brake piston 51, brake pressure control valve 6, works as vehicle
Braking when, make each friction plate 4 successively intervene generate brake force, thus reduce braking the initial stage brake force, reduction to vehicle
Generate impact, improve passenger comfort.
In addition, each brake pressure control valve 6 can adjust the initial pressure that corresponding friction plate 4 is intervened respectively, to change
Become the precedence that each friction plate 4 is intervened, can also change the pressure difference when intervention of each friction plate 4, to change the time of intervention
Interval.The final change procedure for adjusting the brake force exported in brake disc 3, increases brake force step by step, progressively, thus more
Close to the changing rule of brake force needed for the practical braking process of vehicle.
Specifically, the oil outlet 64 of each brake pressure control valve 6 system symmetrical with corresponding 3 two sides of brake disc respectively
Piston cylinder 5 is connected to by secondary pipes, after the oil with certain pressure enters in brake piston cylinder 5, will be lived by braking
Friction plate 4 is pressed in brake disc 3 by plug 51, and pressing force depends on the oil pressure in brake piston cylinder 5, namely depends at this time
Hydraulic coupling in brake fluid cylinder pressure 2.Due to the incompressible characteristic of brake fluid in pipeline, the conduction of velocity of brake pressure is fast, when
After vehicle comes to a complete stop, driver loosens the brake 1, Simultaneous Pressure, pop-off in primary pipeline and secondary pipes, later each
Control piston 61, which resets, under 67 active force of compressed spring, in each brake pressure control valve 6 closes corresponding oil outlet 64, due to pressure
There are frictional force with casing wall when the rebound of contracting spring 67 has delay and mobile control piston 61, so primary pipeline and secondary
Pressure in pipeline has fallen to zero before control piston 61 resets.
There is no hydraulic coupling on each brake piston 51 at this time, but each brake piston 51 still keeps contacting with friction plate.When rubbing
After pad abrasion is thinning, in each braking process, under action of hydraulic force, brake piston 51 can drive friction plate to move to brake disc
It is dynamic, so that it is kept the contact condition with brake disc, eliminates the gap between friction plate and brake disc.
It should be appreciated that described above, the specific embodiments are only for explaining the present invention, is not intended to limit the present invention.By
The obvious changes or variations that spirit of the invention is extended out are still in the protection scope of this invention.
