Abstract
The utility model relates to a kind of brake shoes of high-speed rail motor vehicle wheels, belong to braking field of mechanical technique, it is made of brake block backboard and friction plate combination, brake block backboard is a curved lonely face shape steel metal plate, be intervally arranged open-work in the plate face, and the back side of open-work has with each open-work for concentric enlarged rounded spring groove；Friction plate is to secure friction block on the table top that side view is a T shape frame to constitute, and upright bar is the caudal peduncle of T shape frame, and caudal peduncle insertion open-work is simultaneously embedded in circlip in the spring groove at the open-work back side, friction plate is fixed.A kind of brake shoe of the high-speed rail motor vehicle wheels of the utility model, it is arranged using the combination of friction plate, keep the permeability of brake block good, it is more advantageous to distributing for heat, the friction mode of point contact simultaneously, pressure and frictional force are increased, braking distance is shortened, achievees the effect that emergency braking in a short time.
Description
Technical field
The utility model belongs to braking field of mechanical technique more particularly to a kind of brake of high-speed rail motor vehicle wheels
Piece.
Background technique
Train braking device is to guarantee the equipment of traffic safety to realize train deceleration or out of service.The work of brake
It is mainly to carry out self-friction as principle, using the friction of brake block and brake disc, after the kinetic energy that vehicle is advanced is converted into friction
Thermal energy stops car.A set of good efficient brake system must be able to provide stable, enough, controllable brake weight,
And there is good hydraulic pressure transfer and heat-sinking capability.The knot of the brake apparatus of high-speed rail train especially brake block in the prior art
Structure design is there is also backboard and friction plate fixed form are unreasonable, and brake speed is slow, braking distance is long, and the face contact of use is set
Meter rubs smaller, while the also undesirable problem of the air permeability inside brake block.
Summary of the invention
The utility model provides a kind of brake of high-speed rail motor vehicle wheels for above-mentioned the deficiencies in the prior art
Piece.
A kind of brake shoe of high-speed rail motor vehicle wheels of the utility model, is by brake block backboard and friction plate combination
It constitutes, brake block backboard is a curved lonely face shape steel metal plate, and be intervally arranged open-work in the plate face, and the back side of open-work has with each
Hole is concentric enlarged rounded spring groove；Friction plate is to secure friction block on the table top that side view is a T shape frame to constitute, and is stood
Bar is the caudal peduncle of T shape frame, and caudal peduncle insertion open-work is simultaneously embedded in circlip in the spring groove at the open-work back side, friction plate is fixed.
The friction plate block is that five ribs or six ribs are blocky as a further improvement of the utility model,.
The three row friction plates of front arrangement of the brake block backboard as a further improvement of the utility model, it is intermediate
Six rib block of behavior, five rib block of two sides behavior.
There is the card slot of insertion circlip in the end of the caudal peduncle of the T shape frame as a further improvement of the utility model,.
The friction block has central bore as a further improvement of the utility model,.
A kind of brake shoe of high-speed rail motor vehicle wheels of the utility model fixes backboard and friction plate with circlip,
And the combination arrangement of friction plate, keep the permeability of brake block good, is more advantageous to distributing for heat, while the friction side of point contact
Formula increases pressure and frictional force, shortens braking distance, achievees the effect that emergency braking in a short time.
Detailed description of the invention
Fig. 1 is a kind of this practical new brake shoe positive structure schematic of high-speed rail motor vehicle wheels；
Fig. 2 is a kind of this practical new brake shoe structure schematic diagram of high-speed rail motor vehicle wheels；
Fig. 3 is Fig. 2 A-A to sectional view；
Fig. 4 is a kind of this practical new perspective view of the brake shoe of high-speed rail motor vehicle wheels.
Specific embodiment
A kind of brake shoe of high-speed rail motor vehicle wheels of the utility model is described further with reference to the accompanying drawing:
As shown in Figs 1-4, the brake shoe of a kind of high-speed rail motor vehicle wheels of the utility model, is by brake block backboard
1 and the combination of friction plate 2 constitute, the brake block backboard 1 is a curved lonely face shape steel metal plate, is intervally arranged in the plate face
Hole 3, the back side of open-work 3 have with each open-work 3 for concentric enlarged rounded spring groove 4, the position of fixedly embedded circlip 8.Described
Friction plate 2 is to secure friction block 6 on the table top that side view is a T shape frame 5 to constitute, and upright bar is the caudal peduncle 7 of T shape frame 5, caudal peduncle
There is the card slot 9 of insertion circlip 8 in 7 end, with the position of fixed friction block 6.Caudal peduncle 7 is embedded in open-work 3 and the bullet at 3 back side of open-work
It is embedded in circlip 8 in spring slot 4, friction plate 2 is fixed.Friction block 6 has central bore 10, dissipates the more good ventilation of the present apparatus
It is hot, have both the function of loss of weight, braking flexibility enhancing.
It is that five ribs and six ribs are blocky that 2 pieces of friction plate in the brake shoe, which use,.The front arrangement of brake block backboard 1
Three row friction plates 2, intermediate six rib block of behavior, five rib block of two sides behavior, such permutation and combination increase pressure, frictional force it is same
When, further strengthen the performance of ventilation and heat.
