Description
Technical field
The utility model relates to a kind of break, specifically a kind of double cylinder brake device.
Background technique
The highway communication of China is again more and more flourishing, people are also more and more diversity at the selection traffic tool, electric motor car, motorcycle and mountain bike have become the popular object selected, electric motor car and motorcycle at the traffic tool that to go to than the business district of comparatively dense be people's first-selection, convenient stop, traffic congestion can not be caused, and convenient and swift be the advantage of electric motor car and motorcycle, due to growth in the living standard, hypertension, " three the is high " crowd of high fat of blood and hyperglycaemia becomes common disease, the increasing mountain bike that all starts to ride is lost weight, can to take exercises and low-carbon environment-friendly selects the reason of riding, but existing electric motor car, motorcycle and mountain bike brake system there will be brake failure in the process travelled, especially returning when running at high speed stops does not live the phenomenon of car, the property of people and life can not be protected, electric motor car, the traffic accident that motorcycle and mountain bike cause also gets more and more, head it off is very urgent.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of double cylinder brake device, the brake system stopping electric motor car, motorcycle or mountain bike there will be the phenomenon of brake failure in the process of moving, and there will not be stops does not live the generation of car situation, and property and life are protected.
To achieve these goals, the utility model is achieved through the following technical solutions: a kind of double cylinder brake device, comprise housing, dust ring, seal ring, piston, shoe plate spring, brake block and pilot pin, described surface of shell has circular pumping cylinder I and circular pumping cylinder II, the inwall of pumping cylinder I and pumping cylinder II respectively has groove I and groove II, the width of groove I is 2mm ~ 5mm, the width of groove II is 3mm ~ 8mm, the piston that quantity is two, the dust ring of the seal ring that quantity is two and quantity two is arranged in pumping cylinder I and pumping cylinder II end of to upper successively respectively, dust ring is embedded in groove I, seal ring is embedded in groove II, shoe plate spring is fixed on the side of pumping cylinder I and pumping cylinder II, brake block is above pumping cylinder I and pumping cylinder II, the top of brake block is pilot pin, brake block and pilot pin are fixedly mounted on housing.
The width of described groove I is 3mm, and the width of groove II is 6mm.
The material of described seal ring is polyurethane.
This break use twin-rotor housing effectively can ensure that electric motor car, motorcycle or mountain bike there will not be to stop in running at high speed and not live the generation of car situation, substantially increase stability and Security, though stopping distance is short, and the travelling comfort of braking is also improved, stopped the phenomenon occurring brake failure in running process, property and the life of people are protected.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of pumping cylinder I and pumping cylinder II;
In figure: 1, housing, 2, dust ring, 3, seal ring, 4, piston, 5, shoe plate spring, 6, brake block, 7, pilot pin, 11, pumping cylinder I, 12, pumping cylinder II, 13, groove I, 14, groove II.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
As depicted in figs. 1 and 2, this double cylinder brake device, comprise housing 1, dust ring 2, seal ring 3, piston 4, shoe plate spring 5, brake block 6 and pilot pin 7, described housing 1 surface has circular pumping cylinder I 11 and circular pumping cylinder II 12, the inwall of pumping cylinder I 11 and pumping cylinder II 12 respectively has groove I 13 and groove II 14, the width of groove I 13 is 2mm ~ 5mm, the width of groove II 14 is 3mm ~ 8mm, dust ring 2 is embedded in groove I 13, seal ring 3 is embedded in groove II 14, find in production testing process, when the width of groove I 13 is 3mm, when the width of groove II 14 is 6mm, the effect that is dust-proof and sealing of dust ring 2 and seal ring 3 is best, when the material of seal ring 3 is polyurethane, seal ring 3 is more wear-resisting, high voltage performance, ageing resistance, ozone resistance and oil resistance are best, the seal ring 3 of the piston 4 that quantity is two, quantity two and the dust ring 2 of quantity two are arranged in pumping cylinder I 11 and pumping cylinder II 12 end of to upper successively respectively, shoe plate spring 5 is fixed on the side of pumping cylinder I 11 and pumping cylinder II 12, brake block 6 is above pumping cylinder I 11 and pumping cylinder II 12, the top of brake block 6 is pilot pins 7, and brake block 6 and pilot pin 7 are fixedly mounted on housing 1.
