摘要： A two piece bicycle crank set having two monolithic, thin wall continuous tubular members. The tubular members are coupled midway between two bearing sets within a bracket shell of a bicycle. The coupling connecting the tubular members can include an outer sleeve, an inner sleeve, two exteriorly tapered and internally threaded bushings and a threaded stud. Alternatively, an interference fit coupling connects the tubular members and includes a mortise member and a tenon member.

摘要： A two-piece bicycle crank set comprises two monolithic, thin-wall continuous tubular members. Each tubular member includes a crank arm and a one-half portion of a crank axle, where the crank arm and the portion of the crank axle form a continuous thin-wall tubular shape. The two tubular members are coupled midway between two bearing sets within a bracket shell of a bicycle. The coupling connecting the two tubular members can include an outer sleeve, an inner sleeve, two exteriorly tapered and internally threaded bushings and a threaded stud. Turning the threaded stud positions the bushings to expand the inner sleeve, whereby the crank axle portions of the two tubular members are secured between the inner sleeve and the outer sleeve by the expanding inner sleeve. Alternatively, an interference fit coupling connects the two tubular members and includes a mortise member and a tenon member. The tenon member fits into and interlocks within the mortise member to secure the first tubular member to the second tubular member. The interference fit coupling can further include an attachment bolt and a separation bolt to facilitate assembly and disassembly.
摘要翻译：两片式自行车曲柄组件包括两个整体的薄壁连续管状构件。每个管状构件包括曲柄臂和曲柄轴的一半部分，其中曲柄臂和曲柄轴的部分形成连续的薄壁管状形状。两个管状构件在自行车的支架壳内的两个轴承组之间的中间连接。连接两个管状构件的联接器可以包括外套筒，内套筒，两个外部锥形和内螺纹衬套以及螺柱。旋转螺柱将套管定位成使套筒膨胀，由此两个管状构件的曲柄轴部分通过膨胀的内套筒固定在内套筒和外套筒之间。或者，过盈配合联接器连接两个管状构件，并且包括榫眼构件和榫头构件。榫头构件在榫眼构件内嵌入并互锁，以将第一管状构件固定到第二管状构件。过盈配合联接器还可以包括附接螺栓和分离螺栓以便于组装和拆卸。
