Abstract
The utility model provides a combined force-increasing braking device. The combined force-increasing braking device comprises a lever, a first reset spring, a connecting rod, a rocking rod, a second reset spring, an eccentric wheel, a double hinge, a limiting block and a third reset spring. One end of the lever is simply supported. One end of the first reset spring is fixed, and the other end of the first reset spring is connected to the lever. One end of the connecting rod is simply supported by the lever, and a long and thin groove is formed in the other end of the connecting rod. One end of the rocking rod is connected with the connecting rod through the long and thin groove and can slide freely in the long and thin groove, and the other end of the rocking rod is fixedly connected to the eccentric wheel. One end of the second reset spring is fixed, and the other end of the second reset spring is connected to the rocking rod. The limiting block is fixed. One end of the third reset spring is fixed to the limiting block, and the other end of the third reset spring is fixed to the double hinge. The eccentric wheel makes close contact with the double hinge under the action of the third reset spring. The combined force-increasing braking device is good in force increasing effect, high in braking efficiency, good in braking effect, simple in structure, easy to realize and good in overall effect, and a transmission chain is short.
Description
Technical field
The utility model relates to a kind of combination boosting brake device.
Background technology
Disc brake is time to conduct as power with hydraulic pressure or other mechanisms in brake, clamps brake disc, allows wheel decelerates.So the size of conductance is very large on braking effect impact.Existingly carry out disc brake with hydraulic gear, complex structure, and also cost is high.Manpower is very limited again, therefore force-increasing mechanism has very large use at this.
Utility model content
The defect existing for prior art, the purpose of this utility model is to provide a kind of combination boosting brake device, makes braking effect better, and stop mechanism is simple.
For achieving the above object, the utility model adopts following technical proposals:
A kind of combination boosting brake device, comprise lever, the first retracing spring, connecting rod, rocking bar, the second retracing spring, eccentric wheel, double-strand chain, limiting stopper and the 3rd retracing spring, described lever one end freely-supported, described first retracing spring one end is fixed, the other end is connected on lever, described connecting rod one end freely-supported is on lever, the other end of connecting rod has elongated slot, one end of described rocking bar is connected with connecting rod by elongated slot, the coupling end of rocking bar can be free to slide in elongated slot, the rocking bar other end is connected on eccentric wheel, described second retracing spring one end is fixed, the other end is connected on rocking bar, described limiting stopper is fixed, described the 3rd retracing spring one end is fixed on limiting stopper, the other end is fixed on double-strand chain, described eccentric wheel and double-strand chain be close contact under the effect of the 3rd retracing spring.
Compared with prior art, the utlity model has following advantage:
The utility model reinforcement effect is good, and braking efficiency is high, and braking effect is good; Simple in structure, easily to realize, messenger chain is short, and whole structure is good.The suitable especially place that is arranged on battery-driven car service brake, for improving deceleration and stopping performance.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of combination reinforcement stop mechanism.
The specific embodiment
Below in conjunction with accompanying drawing, to preferred embodiment of the present utility model, details are as follows:
Referring to Fig. 1, a kind of combination boosting brake device, comprise lever 1, the first retracing spring 2, connecting rod 3, rocking bar 4, the second retracing spring 5, eccentric wheel 6, double-strand chain 7, limiting stopper 8 and the 3rd retracing spring 9, described lever 1 one end freely-supported, described first retracing spring 2 one end are fixed, the other end is connected on lever 1, described connecting rod 3 one end freely-supporteds are on lever 1, the other end of connecting rod 3 has elongated slot, one end of described rocking bar 4 is connected with connecting rod 3 by elongated slot, the coupling end of rocking bar 4 can be free to slide in elongated slot, rocking bar 4 other ends are connected on eccentric wheel 6, described second retracing spring 5 one end are fixed, the other end is connected on rocking bar 4, described limiting stopper 8 is fixing, described the 3rd retracing spring 9 one end are fixed on limiting stopper 8, the other end is fixed on double-strand chain 7, described eccentric wheel 6 and double-strand chain 7 close contact under the effect of the 3rd retracing spring 9.
