Description
Technical field
The present invention relates to Brake for vehicle technical field, particularly a kind of multisection type brake-shoe for drum brake.
Background technology
Brake is the dress for having the function of to make moving component (or movable machinery) slow down, stop or keep halted state etc.
Put, be the machine components for making the movement parts in machinery stop or slow down, be commonly called as brake, lock.Brake is mainly by frame processed, brake component
Formed with manipulation device etc..Some brakes are also equipped with the automatic regulating apparatus in brake component gap, in order to reduce braking moment and
Structure size, brake are commonly mounted on the high speed shaft of equipment, but the higher large scale equipment of security requirement should be then mounted in and leaned on
On the slow-speed shaft of nearly equipment working portion.
In Brake for vehicle, there is a kind of brake using a shoe type drum brake, a hoof mechanism type brake master
It is divided into two classes：One kind be it is mechanical, using it is most common be pneumatic type cam mechanism hoof；Another kind of is fluid pressure type：It is
Piston hoof is promoted with hydraulic cylinder.The both ends stroke of cam hoof passage brake-shoe is equal so that brake-shoe turns in the other end
Dynamic be connected under the action of support shaft rotates along supporting point, so that the brake block on brake-shoe and brake drum friction, so that
Realize the braking of vehicle, the effect that pneumatic cam mechanism is received due to one end of brake-shoe in the brake of Zhang Ti mechanisms is opened first
Open so that braking brake block at the end gets off drag friction pad wear inequality with brake drum friction, long term first
Even, so as to cause the braking effect of brake bad, the friction plate replacement cycle is short, and brake service cost greatly increases, for
For oversize vehicle, the above problem is especially apparent.
The content of the invention
The goal of the invention of the present invention is：For above-mentioned problem, there is provided a kind of multistage for drum brake
Formula brake-shoe, by improving the structure design of brake-shoe, using multisection type brake-shoe drive mechanism so that the friction on brake-shoe
Piece uniformly can carry out friction catch with brake drum, substantially increase the service life of brake-shoe, ensure that using the present invention
The brake of the brake-shoe of structure has good braking effect, its installation simple in structure and easy to maintain, solves existing big
The problem of type vehicle shoe brake braking effect is bad, and brake use cost is high.
The technical solution adopted by the present invention is as follows：
The multisection type brake-shoe for drum brake of the present invention, including the brake-shoe body being detachably connected with brake disc；
The brake-shoe body includes active hoof and trailing shoe, one end of the active hoof and the hydraulic pressure of driving brake-shoe body opening and closing or
Person's cam mechanism connects, and the other end trailing shoe of active hoof is sequentially connected so that trailing shoe can be realized synchronous whole with active hoof
Body opening and closing；The active hoof is equipped with the installing plate perpendicular to brake bottom plate with trailing shoe, for installing friction plate；Institute
State and the return spring consistent with both directions is also associated between active hoof and trailing shoe, the return after being opened for brake-shoe.
Due to using the above structure, by brake-shoe subsection setup, and using drive coordination action side between each brake-shoe
Formula connects so that braking can be by overall uniform brake drum effect, so as to ensure that the friction plate on brake-shoe can be uniform
Effective brake drum effect, so as to produce the friction catch effect of balance and stability, and then realizes the good braking effect of brake
Fruit, its is simple in structure, install convenient, and practicality is good, and the brake-shoe of segmented ensure that the uniform stressed of friction plate, so as to ensure
The service life of friction plate, greatly reduces the replacement frequency of friction plate, reduces the use cost of brake, has good
Good use value；Reset position-limit mechanism can ensure trailing shoe in multisection type brake-shoe can parking position accuracy, ensure its work
Use effect.
Further, the drive connection end of the active hoof and trailing shoe is respectively equipped with runner one and runner two；Institute
It is that the runner being toothed around, runner one and runner two are intermeshed installation by the gear teeth thereon to state runner one and runner two.
Further, the gearratio of the runner one and runner two is 1:1.
Further, the runner one is equal with the thickness of runner two, and is equal to the thickness of installing plate；The installation
The thickness of plate is 5mm-8mm.
Further, the drive connection end of the active hoof and/or trailing shoe is equipped with connecting hole, available for by actively
This of hoof and/or trailing shoe end are relatively fixed with back-plate to be connected.
Further, the active hoof is equipped with a connection end, for the hydraulic pressure or cam machine with driving its opening and closing
Structure connects.
Further, the installing plate is curved panel, which is provided with some heat emission holes；Along the lateral wall of the installing plate
On be uniformly equipped with friction plate, the active hoof is set independently of each other with the friction plate on trailing shoe.
Further, the both ends of the return spring are fixedly connected with active hoof and trailing shoe respectively；The return spring
It can be connected between active hoof and trailing shoe by a tooth form cam, the tooth form cam is used to adjust active hoof and trailing shoe
The distance between brake drum of brake.
Due to the adoption of the above technical scheme, the beneficial effect of the multisection type brake-shoe for drum brake of the invention
It is：Active hoof and trailing shoe are installed using the rotation intermeshing with the gear teeth, when active hoof is subject to the tension force of cam mechanism,
Active hoof can drive at the same time realizes braking purpose so as to which brake-shoe turns to be bonded with brake drum synchronous with active hoof；Work as master
When return spring on dynamic hoof and/or trailing shoe recovers the position of brake-shoe, the active hoof and trailing shoe that can ensure two groups are answered
The synchronization of position and uniformity, so as to ensure the stability of whole brake structural, so that brake can be chronically at one
Stable and good braking effect；Said structure is simple, and effect propety is good, be brake structural improve on one greatly into
Step.Return spring can be respectively acting on active hoof and trailing shoe, ensure the integral reset effect of brake-shoe, so as to ensure car
Normal driving, and be ready for next time stable braking, by setting tooth form cam by return spring and brake-shoe
Connection so that it can carry out the gap adjustment between friction plate and brake drum after friction plate is constantly worn, so as to ensure good
Good braking effect, its structural stability are good；Mutually independent friction plate causes its not squeezed mutually in mechanism each
Pressure, avoids the phenomenon of friction plate fin from occurring, further enhances the braking ability of brake, even if the friction in some
One of piece is damaged when needing replacing, and other friction plates can also continue to keep good friction catch effect, ensure that car
Security when driving, avoids causing the generation of traffic accident since friction plate damages in roadway way.
In conclusion its simple in structure, easy for installation, use of the multisection type brake-shoe for drum brake of the present invention
Performance is good；Manufacture craft is simple, and use cost is low；Stable structure, good braking effect；Improve the safety during vehicle driving
Property；With good use value, it is adapted to promote and apply.
