Technical field
The present invention relates to vehicle brake apparatus technical field, particularly relate to a kind of brake shoe assembly.
Background technology
Vehicle brake is the vitals of vehicle, is to ensure that the key of traffic safety.The most conventional vehicle
Brake includes drum brake and disk brake.Drum brake is mainly by base plate, brake drum, braking
The parts compositions such as hoof, wheel cylinder, return spring.Brake drum is arranged on wheel hub, along with wheel rotates together,
When braking, wheelcylinder piston promotes brake-shoe compressing brake drum, and brake drum, by friction eceleration, forces wheel
Stop operating.Drum brake is the most traditional a kind of brake, because it has low price, braking
Can well wait advantage to be widely used, wherein, brake-shoe is the key component of drum brake.Existing skill
In art, if Authorization Notice No. is a kind of brake shoe assembly disclosed in the utility model of " CN203477135U ",
Being that brake-shoe and friction plate are fixed by the mode using riveted, above-mentioned fixed form is in order to ensure that riveted is strong
Degree, usual riveted holes quantity is more, adds the workload that friction plate is changed, and during riveted holes negligible amounts,
The frictional force of brake-shoe is restricted and causes stopping power to decline.
Summary of the invention
In order to solve technical problem present in background technology, the present invention proposes a kind of brake shoe assembly, real
Having showed the improvement to brake shoe assembly structure, its friction lining board is changed convenient, and frictional damping superior.
A kind of brake shoe assembly that the present invention proposes, for carrying out car braking with brake drum friction, including system
Dynamic hoof and friction lining board, brake-shoe includes brake and is fixed on above-mentioned brake near friction lining board one
Some connecting portions of side, connecting portion includes connecting-rod body and friction taps, friction taps and connecting-rod body away from
Brake one end is fixed, and the middle part of connecting-rod body is provided with annular protrusion, friction lining board corresponding connection parts position
Install the conduit being equipped with some through friction lining board thickness directions, the length phase of the length of connecting-rod body and conduit
Deng, the internal diameter of the conduit external diameter more than connecting-rod body and the external diameter less than annular protrusion, above-mentioned conduit correspondence is even
The annular protrusion position of extension bar body is provided with annular groove, and the maximum outside diameter of friction taps is less than conduit internal diameter, system
Dynamic hoof is fixed with coordinating of connecting portion by conduit with friction lining board, and connecting-rod body uses elastomeric material system
Making, friction taps uses hard alloy to make.
Preferably, from away from connecting-rod body one end near connecting-rod body one end, the sectional area of friction taps by
The least.
Preferably, the quantity of connecting portion is 8-12.
Preferably, connecting portion is evenly distributed on connection body.
Preferably, annular protrusion is less than annular protrusion and company with connecting-rod body near the distance being connected body one end
Extension bar body is away from the distance connecting body one end.
In above-mentioned brake shoe assembly, due to annular protrusion and the setting of annular groove, by conduit and connecting portion
Cooperation, brake-shoe is assembled with friction lining board, due to avoid use riveted connected mode, reduce
Working strength in assembling process；When brake shoe assembly is in non-brake state, due to connecting-rod body
Length is equal with the length of conduit, and friction taps passes the rubbing surface of friction lining board；When brake shoe assembly is in
During on-position, due to the effect of retrothrust, brake-shoe and friction lining board are in is close to state, friction side
Head is in, with the rubbing surface of friction lining board, the state of flushing, and connecting-rod body is in compressive state, meanwhile, and friction side
Head is by away from the stress in brake-shoe direction, so that contact friction between friction lining board with brake drum
Power is bigger, therefore, it can promote stopping power during brake shoe assembly on-position.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of brake shoe assembly that the present invention proposes.
Detailed description of the invention
As it is shown in figure 1, the structural representation of a kind of brake shoe assembly that Fig. 1 is the present invention to be proposed.
With reference to Fig. 1, in one embodiment, a kind of brake shoe assembly that the present invention proposes, it is used for and brake drum
Friction carries out car braking, and including brake-shoe 1 and friction lining board 2, brake-shoe 1 includes brake 11 He
It is fixed on the above-mentioned brake 11 10 connecting portions 12 near friction lining board 2 side and connecting portion 12 is equal
Even being distributed on brake 11, connecting portion 12 includes connecting-rod body 121 and friction taps 122, friction side
122 fix away from brake 11 one end with connecting-rod body 121, from away from connecting-rod body 121 one end to
Near connecting-rod body 121 one end, the sectional area of friction taps 122 is gradually reduced, in connecting-rod body 121
Portion is provided with annular protrusion 3, and friction lining board 2 corresponding connection parts 12 position is provided with 10 through friction lining boards
The conduit 4 of 2 thickness directions, the length of connecting-rod body 121 is equal with the length of conduit 4, the internal diameter of conduit 4
External diameter more than connecting-rod body 121 and the external diameter less than annular protrusion 3, the corresponding connecting-rod body of above-mentioned conduit 4
Annular protrusion 3 position of 121 is provided with annular groove 41, and the maximum outside diameter of friction taps 122 is less than conduit 4
Internal diameter, brake-shoe 1 is fixed with coordinating of connecting portion 12 by conduit 4 with friction lining board 2, connecting rod
Body 121 uses elastomeric material to make, and friction taps 122 uses hard alloy to make.
In the above-described embodiments, due to annular protrusion 3 and the setting of annular groove 41, by conduit 4 and company
Connect the cooperation in portion 12, brake-shoe 1 is assembled with friction lining board 2, connect owing to avoiding use riveted
Mode, reduces the working strength in assembling process；When brake shoe assembly is in non-brake state, due to
The length of connecting-rod body 121 is equal with the length of conduit 4, and friction taps 122 passes rubbing of friction lining board 2
Wiping face；When brake shoe assembly is in on-position, due to the effect of retrothrust, brake-shoe 1 and friction
Liner plate 2 is in is close to state, and friction taps 122 is in, with the rubbing surface of friction lining board 2, the state of flushing, even
Extension bar body 121 is in compressive state, and meanwhile, friction taps 122 is subject to the stress away from brake-shoe 1 direction,
So that the contact friction force between friction lining board 2 and brake drum is bigger, therefore, it can promote braking
Stopping power during hoof assembly on-position.
In the technical scheme improved further, annular protrusion 3 is close with connecting-rod body 121 is connected body one
The distance of end less than annular protrusion 3 and connecting-rod body 121 away from being connected the distance of body one end, due to, when
Friction lining board 2 wears up at annular groove 41, represents and needs to change friction lining board 2, and above-mentioned design can
So that friction lining board 2 is more fully utilized.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention not office
Being limited to this, any those familiar with the art is in the technical scope that the invention discloses, according to this
The technical scheme of invention and inventive concept thereof in addition equivalent or change, all should contain the protection in the present invention
Within the scope of.
