 This prototype chainless bike suggests the future of cycling could be ceramic 这辆无链条自行车原型车显示未来的自行车可以是陶瓷制成的 The future of cycling may just have been revealed at Eurobike, an annual cycling trade show that is taking place right now in Germany. At the event, a company called CeramicSpeed took the wraps off a prototype bike that looks like something straight out of a science-fiction movie, complete with a revolutionary new chainless drive system that promises to be a revelation for riders, improving speed and efficiency without an increase in power. 自行车的未来有可能刚刚才在欧洲自行车展上露出真相，这是一个目前正在德国举行的年度自行车展销会。展会上，一家名为CeramicSpeed的公司展出了一辆像是从科幻电影中走出来的自行车样板车，该车采用一套无链条驱动系统，肯定会给车手们带来惊喜，它提高了车速和骑行效率，但并不需要使更多的力。 ceramic：陶瓷 prototype：原型，雏形， revelation：意外的发现 CeramicSpeed developed its new DrivEn system in conjunction with the University of Colorado’s mechanical engineering department. The innovative crankset does away with the traditional chain drive, replacing it with a system that uses 21 ceramic bearings to transfer power generated from the pedals through front- and rear-mounted pinions instead. This cuts down on the number of moving parts involved with the drivetrain considerably. CeramicSpeed公司和科罗拉多大学的机械工程系合作开发了叫做DrivEn的驱动系统。创新的大齿盘代替了传统的链条驱动，从而使用由21个陶瓷轴承组成的系统，它把脚蹬子发出的力通过安装在前面和后面的小齿盘转化成驱动力。这大大减少了与传动系统有关的活动零件的数量。 The DrivEn prototype does away with the chain, derailleurs, and pulleys found on most traditional bikes, which has the effect of reducing the number of friction points found in the drive system. As the chain slides through a typical cycling crankset, there are eight points where it can generate friction, lowering efficiency as a result. But CeramicSpeed’s new drive drops that number down to just two friction points, which means more of the power that is generated from pedaling goes directly into pushing the bike forward, translating into more speed for less work. DrivEn新系统取消了传统自行车上的链条、变速器和滑轮，其作用是减少驱动系统中的摩擦点的数量。当链条通过循环曲轴箱滑动时，原本会有8个摩擦点，这降低了驱动效率。但CeramicSpeed的新系统把摩擦点降低到了2个，表明从脚蹬子传来的力更直接转化成驱动力，就是说用更少的力达到更高的速度。 According to CeramicSpeed, the DrivEn actually gets more efficient at higher speeds. In fact, the company claims that when a rider hits 380 watts of output, efficiency actually climbs to 99 percent, something that is unheard of on a traditional bike model. If true, that means that nearly all of the power generated by a rider is being transferred directly to the wheels of the bike. That should lead to faster rides for both serious and casual cyclists alike. 据CeramicSpeed公司介绍，这套新系统实际上在高速时更有效。事实上，该公司声称当一个骑手发出了380瓦的功率输出时，效率能达到99%，这在传统自行车上是不可想象的。如果这是真的，就意味着一个骑手发出的全部力量几乎完全能转化成驱动力。这将使得无论是专业骑手还是休闲骑手都能骑得更快速。 It is unclear when — or even if — the DrivEn system will be brought to market, but it does show the level of technology and innovation the cycling industry is toying with at the moment. The prototype was even good enough to earn CeramicSpeed a Design Award at Eurobike, indicating a product that will be worth keeping an eye on in the future. 目前还不清楚这种DrivEn系统何时-或甚至会不会被引进消费市场，但它确实显示了目前自行车行业技术和创新水平正在努力的方向。这个优秀的原型设计甚至在欧洲自行车展上为CeramicSpeed赢得了一项设计奖，这表明这款产品的未来非常值得期待。 👇 |
