Model utility content
In order to solve the technical problem existed in background technique, the utility model proposes a kind of brake shoe assembly, achieving the improvement to brake shoe assembly structure, its friction lining board is changed convenient, and friction catch superior.
A kind of brake shoe assembly that the utility model proposes, for carrying out car brakeing with brake drum friction, comprise brake shoe and friction lining board, brake shoe comprises brake and is fixed on the some joints of above-mentioned brake near friction lining board side, joint comprises connecting-rod body and friction taps, friction taps and connecting-rod body are fixed away from brake one end, the middle part of connecting-rod body is provided with annular protrusion, friction lining board corresponding connection parts position is provided with the conduit of some through friction lining board thickness directions, the length of connecting-rod body is equal with the length of conduit, the internal diameter of conduit is greater than the external diameter of connecting-rod body and is less than the external diameter of annular protrusion, the annular protrusion position of the corresponding connecting-rod body of above-mentioned conduit is provided with annular groove, the maximum outside diameter of friction taps is less than conduit internal diameter, brake shoe is fixed with coordinating of joint by conduit with friction lining board, connecting-rod body adopts elastic material to make, friction taps adopts cemented carbide to make.
Preferably, from away from connecting-rod body one end near connecting-rod body one end, the sectional area of friction taps reduces gradually.
Preferably, the quantity of joint is 8-12.
Preferably, joint is evenly distributed on and connects on body.
Preferably, annular protrusion is less than annular protrusion with connecting-rod body away from the distance being connected body one end with connecting-rod body near the distance being connected body one end.
In above-mentioned brake shoe assembly, due to the setting of annular protrusion and annular groove, by coordinating of conduit and joint, brake shoe and friction lining board are assembled, uses riveted Placement owing to avoiding, reduce the working strength in assembling process; When brake shoe assembly is in non-brake state, because the length of connecting-rod body is equal with the length of conduit, friction taps passes the rubbing surface of friction lining board; When brake shoe assembly is in braking state, due to the effect of retrothrust, brake shoe and friction lining board are in is close to state, friction taps is in the rubbing surface of friction lining board the state of flushing, and connecting-rod body is in compressive state, simultaneously, friction taps is subject to the stress away from brake shoe direction, thus make contact friction force between friction lining board and brake drum larger, therefore, can Hoist braking hoof assembly braking state time stopping power.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of brake shoe assembly that the utility model proposes.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of brake shoe assembly that the utility model proposes.
With reference to Fig. 1, in one embodiment, a kind of brake shoe assembly that the utility model proposes, for carrying out car brakeing with brake drum friction, comprise brake shoe 1 and friction lining board 2, brake shoe 1 comprises brake 11 and is fixed on above-mentioned brake 11 near 10 joints 12 of friction lining board 2 side and joint 12 is evenly distributed on brake 11, joint 12 comprises connecting-rod body 121 and friction taps 122, friction taps 122 and connecting-rod body 121 are fixed away from brake 11 one end, from away from connecting-rod body 121 one end near connecting-rod body 121 one end, the sectional area of friction taps 122 reduces gradually, the middle part of connecting-rod body 121 is provided with annular protrusion 3, friction lining board 2 corresponding connection parts 12 position is provided with the conduit 4 of 10 through friction lining board 2 thickness directions, the length of connecting-rod body 121 is equal with the length of conduit 4, the internal diameter of conduit 4 is greater than the external diameter of connecting-rod body 121 and is less than the external diameter of annular protrusion 3, annular protrusion 3 position of the corresponding connecting-rod body 121 of above-mentioned conduit 4 is provided with annular groove 41, the maximum outside diameter of friction taps 122 is less than conduit 4 internal diameter, brake shoe 1 is fixed with coordinating of joint 12 by conduit 4 with friction lining board 2, connecting-rod body 121 adopts elastic material to make, friction taps 122 adopts cemented carbide to make.
In the above-described embodiments, due to the setting of annular protrusion 3 and annular groove 41, by coordinating of conduit 4 and joint 12, brake shoe 1 and friction lining board 2 are assembled, uses riveted Placement owing to avoiding, reduce the working strength in assembling process; When brake shoe assembly is in non-brake state, because the length of connecting-rod body 121 is equal with the length of conduit 4, friction taps 122 passes the rubbing surface of friction lining board 2; When brake shoe assembly is in braking state, due to the effect of retrothrust, brake shoe 1 and friction lining board 2 are in is close to state, friction taps 122 is in the rubbing surface of friction lining board 2 state of flushing, and connecting-rod body 121 is in compressive state, simultaneously, friction taps 122 is subject to the stress away from brake shoe 1 direction, thus make contact friction force between friction lining board 2 and brake drum larger, therefore, can Hoist braking hoof assembly braking state time stopping power.
