摘要： A right crank arm assembly (1) for a bicycle, comprises a right crank arm (5) and at least one front sprocket (10) coupled with the crank arm at at least one coupling portion (44) of the crank arm. The front sprocket (10) has an inner side adapted, in use, to face towards the frame of the bicycle and an outer side opposite the inner side. The assembly (1) comprises at least one first crank arm element (30) which acts in contact with the front sprocket (10) on one of said sides and at least one second crank arm element (35) which acts in contact with the front sprocket (10) on the other of said sides. The contact action of the crank arm elements on the two opposite sides of the front sprocket prevents the twisting deformation of the front sprocket during pedalling. Such a deformation would cause a reduction in the transmission efficiency of the right crank arm assembly.

摘要： Double crank alternating cycle traction system in which two independent free-turning cranks with a dynamic articulation at the place where the force is applied are strategically added to a conventional pedal cycle. The operation of the resulting mechanical composition increases the mechanical advantage of the original system. The invention is applicable to pedal cycles, mainly all kinds of bicycles, i.e. bicycles, tricycles, four-wheeled bicycles, moved by the extremities of the human body, i.e. the hands or feet.

摘要： Provided is a pedal force sensor which, in pedal force detection utilizing an elastic body, can detect pedal force over a wide range and reduce detection errors originating from variation in the attachment position or length etc. of the elastic body. Linkage between a drive wheel (30) that is fixed to a crankshaft (14) and a sprocket (50) that transmits rotary force of the crankshaft (14) to a propelling vehicle wheel is effected by a plurality of springs (80 to 90), and furthermore the space between each spring (80 to 90) and compression means thereof is set in such a way that the compression commencement timings of the plurality of springs (80 to 90) are offset. When detecting pedal force from the phase difference of the drive wheel (30) and the sprocket (50), the number of springs that are utilized changes in accordance with the range of the phase difference. In other words, since the spring constant that is utilised differs in accordance with the range of the phase difference, the pedal force can be detected on the basis of this changing spring constant. As a result, the relationship between the amount of displacement and the pedal force is made to be nonlinear, and a pedal force sensor is thereby obtained that approximates the desired detection characteristics.

摘要翻译： 提供一种踏板力传感器，其在利用弹性体的踏板力检测中能够在宽范围内检测踏板力，并且减少由弹性体的附接位置或长度等的变化引起的检测误差。 固定到曲轴（14）的驱动轮（30）与将曲轴（14）的旋转力传递到推进车轮的链轮（50）之间的连接通过多个弹簧（80〜90）进行， 并且此外，各弹簧（80〜90）与其压缩装置之间的空间被设定为使得多个弹簧（80〜90）的压缩开始定时偏移。 当从驱动轮（30）和链轮（50）的相位差检测踏板力时，利用的弹簧数量根据相位差的范围而改变。 换句话说，由于利用的弹簧常数根据相位差的范围而不同，因此可以基于该变化弹簧常数来检测踏板力。 结果，位移量和踏板力之间的关系被做成非线性，由此获得逼近期望的检测特性的踏板力传感器。
