Description

自行车省力传动装置 技术领域
本发明属于非机动车即自行车、 三轮车等车辆的技术领域, 进一歩讲是一 种非机动车的自行车省力传动装置。
背景技术
现有普通自行车由于受踩踏说位置的限制, 链盘上用于与踏板连接的单臂杆 的长度比较短, 不太省力。
发明内容
为了解决上述问题, 本发明提供了一种自行车省力传动杆, 它可增加传动 力臂的长度, 从而达到省力的目的。
本发明的技术方案是这样构成的, 一种自行车省力传动装置, 它包括传动 件、 连接于传动件一端的踏板或手柄装置、 连接于传动件另一端的一对 "Z "字 形连杆, 踏板或手柄装置与传动件连接的连接作用中心线及两个 "z"字形连杆 与传动件连接的连接作用中心线相互平行; 每个 "z"字形连杆均包括一对相互 平行的横杆和固接于两横杆之间的立杆, 其中第二横杆均用于和自行车车架转 动连接, 且两个 "Z "字形连杆的第一横杆之间的轴心距等于第二横杆之间的轴 心距; 其特征在于: 所述传动件由连接板和动力杆组成 , 两个 "Z "字形连杆 的第一横杆分别与连接板两端转动连接, 动力杆的一端固定连接在连接板中部, 动力杆的另一端与踏板或手柄装置连接, 且两个 "z"字形连杆的第一横杆与连 接板的转动连接位置分别位于动力杆与连接板的固定连接位置的两侧; 其中一 个 "Z "字形连杆固定连接有以该 "Z "字形连杆的第二横杆轴心为转动中心的 传动链盘, 所述传动链盘用来带动自行车飞轮或者通过自行车变速链盘带动自 行车飞轮。
使用时, 先将两个 " z"字形连杆的第二横杆连接在自行车前端或后端, 使 其与自行车车架转动连接, 再将传动链盘通过传动链条与自行车飞轮连接, 或 者将传动链盘与自行车变速链盘 (自行车变速链盘为多片链盘固定连接而成) 中的一片链盘进行连接, 接着使自行车变速链盘中的另一片链盘通过另一传动 链条与自行车飞轮进行连接 (这里自行车变速链盘仅起到导轮的作用)。 当踩动 踏板装置 (或摇动手柄装置) 带动传动件转动时, 由于两个 "Z "字形连杆的第 二横杆与自行车车架转动连接, 且两个 "z"字形连杆的第一横杆之间的轴心距 等于第二横杆之间的轴心距, 因此两个 "Z "字形连杆都只能分别绕其第二横杆 的轴心线做圆周运动, 从而通过带动与其中一个 "Z "字形连杆固定连接的传动 链盘的转动, 来带动自行车飞轮转动, 或者由传动链盘带动自行车变速链盘转 动, 再通过自行车变速链盘带动自行车飞轮转动。
较之已有技术而言, 本发明由于将传动件设置成由连接板和动力杆组成, 两个 "Z "字形连杆的第一横杆分别与连接板两端转动连接, 动力杆的一端固定 连接在连接板中部, 动力杆的另一端与踏板或手柄装置连接, 且两个 "Z "字形 连杆的第一横杆与连接板的转动连接位置分别位于动力杆与连接板的固定连接 位置的两侧; 因此, 当通过作用力使踏板或手柄装置向下 (如图 1 所示垂直纸 面方向向下) 转时, 动力杆上端对连接板施加的向下作用力转移到连接板的中 部 (固定连接点), 并通过连接板使得两个 "Z "字形连杆的第一横杆成为一个 整体, 使得连接板可同时带动两个 "z "字形连杆的第一横杆向下运动, 这样即 可使踏板或手柄装置在向下转动的同时顺利带动两个 "z "字形连杆作同歩圆周 运动, 此外由于该结构力臂更长且动力杆能根据需要加长, 因此真正达到了省 力效果。

具体实施方式
下面结合说明书附图和具体实施例对本发明内容进行详细说明:
实施例 1
如图 1所示, 本发明自行车省力传动装置实施例 1它包括传动件 1、连接于 传动件 1一端的踏板或手柄装置 2、 连接于传动件 1另一端的一对" Z "字形连 杆 3, 踏板或手柄装置 2与传动件 1连接的连接作用中心线 20及两个 "Z "字形 连杆 3与传动件连接的连接作用中心线 111、 112相互平行; 每个" V,字形连 杆 3均包括一对相互平行的横杆 31、 32和固接于两横杆之间的立杆 33, 其中第 二横杆 32均用于和自行车车架转动连接 (可将第二横杆 32设置为轴杆, 在轴 杆外套置与轴杆转动连接的轴套, 使轴套与自行车车架固定连接), 且两个 " Z " 字形连杆 3的第一横杆 31之间的轴心距等于第二横杆 32之间的轴心距; 其特 征在于: 所述传动件 1由连接板 11和动力杆 12组成, 两个 "Z "字形连杆 3的 第一横杆 31分别与连接板 11两端转动连接, 动力杆 12的一端固定连接在连接 板 11中部 (所述中部是指动力杆 12与连接板 11的固定连接位置位于两个 "Z " 字形连杆 3的第一横杆 31与连接板 11的连接孔所在位置之间, 并不要求其位 于正中的位置), 动力杆 12的另一端与踏板或手柄装置 2连接; 且两个" Z "字 形连杆 3的第一横杆 31与连接板 11的转动连接位置分别位于动力杆 12与连接 板 11的固定连接位置的两侧; 其中一个 "Z "字形连杆 3固定连接有以该 "Z " 字形连杆 3的第二横杆 31轴心为转动中心的传动链盘 5, 所述传动链盘 5用来 带动自行车飞轮或者用来通过自行车变速链盘 8带动自行车飞轮。
所述传动链盘 5最好固定连接在 "Z "字形连杆 3的立杆 33与第二横杆 32 连接的端部上(或者所述传动链盘 5也可根据调整需要而安装在第二横杆 32的 任意位置上)。
所述踏板或手柄装置 2包括转动连接在动力杆 12下端部的动力端连杆 4、 与动力端连杆 4的一端部连接的踏板或手柄 22以及与动力端连杆 4的另一端部 垂直固定连接的立臂 23, 所述立臂 23的另一端与自行车中轴 6的轴杆 7连接, 所述自行车中轴 6的轴套与轴杆 7转动连接, 且自行车中轴 6的轴套和轴杆 7 的轴线均与动力端连杆 4的轴线平行。
所述踏板或手柄 22通过摆臂 21与动力端连杆 4的一端部固定连接, 且踏 板或手柄 22能绕动力端连杆 4轴线做圆周运动。 通过摆臂 21延长了踏板或手 柄到动力端连杆轴线的传动力臂, 使用起来更加省力。
所述自行车中轴 6的轴杆 7还可与自行车变速链盘 8转动连接或者固定连 接。
上述 "Z "字形连杆的横杆与立杆之间的夹角的最佳度数为 90度, 当然并 不局限于 90度。
为了在自行车两侧都安装自行车省力传动装置, 以便交替传动, 上述 " Z " 字形连杆 3的第二横杆 32的端部 321与另一自行车省力传动装置中的立杆固定 连接, 它们之间的连接方式可以是任意的, 从而两个自行车省力传动装置的" Z " 字形连杆可共用第二横杆 32。
为了便于人们像使用现有普通自行车一样采用左右脚交替的方式进行踩踏 驱动, 所述自行车中轴 6的轴杆 7另一端部还设有用于与另一踏板或手柄装置 的立臂 23连接的轴杆连接端 71。
实施例 2
如图 2所示, 实施例 2与实施例 1的区别在于: 踏板或手柄 22直接转动连 接在动力端连杆 4的外端部, 而不是通过摆臂 21与动力端连杆 4进行连接。
