Description
本发明相关于一种脚踏车,特别是相关于一种脚踏车的油压煞车装置。The present invention relates to a bicycle, and more particularly to a hydraulic brake device associated with a bicycle.
随着全球暖化及空气污染议题的发烧,以人力脚踏驱动的脚踏车已逐渐取代汽车、机车、及电动车,促进了脚踏车的各种改良。由于脚踏车的煞车器攸关生命安全,因此煞车器是脚踏车所有改良中最重要的一环。With the global warming and air pollution issues, bicycles powered by human foot pedals have gradually replaced cars, locomotives, and electric vehicles, and have promoted various improvements in bicycles. Since the bicycle's brakes are vital to life, the brakes are the most important part of any improvement in the bicycle.
由于油压碟式煞车器即使在雨天或在路面情况不佳时仍然能发挥其煞车效果,脚踏车的煞车器中油压碟式煞车器属所有煞车器中耐候性最佳者。油压碟式煞车器的煞车原理是藉由煞车钳夹住煞车盘的两侧盘面,迫使煞车盘转速降低而达到煞车的效果。Because the hydraulic disc brakes can still exert their braking effect even in rainy days or when the road surface is not good, the hydraulic disc brakes in the bicycle brakes are the best weather resistance among all the brakes. The brake principle of the hydraulic disc brake is to clamp the two sides of the brake disc by the tongs, forcing the speed of the brake disc to decrease and achieve the effect of braking.
然而,由于油压碟式煞车器在煞车时,煞车钳与煞车盘相磨擦所产生的热能会传导至煞车油而导致煞车油温度升高,进而造成煞车油变质、以及煞车油流动性增加。煞车油变质会导致活塞无法正常运作,而煞车油流动性增加则会造成漏油的问题,二者皆会导致煞车失效而严重影响生命安全。However, when the hydraulic disc brake is braked, the heat generated by the friction between the brake caliper and the brake disc is transmitted to the brake oil, which causes the temperature of the brake oil to rise, thereby causing deterioration of the brake oil and an increase in the fluidity of the brake oil. Deterioration of the brake oil will cause the piston to fail to operate normally, and the increased fluidity of the brake oil will cause oil leakage problems, both of which will cause the brake to fail and seriously affect the safety of life.
