Description

一种自行车传动装置和具有该装置的自行车及电动自行车 技术领域
本发明涉及一种自行车传动装置和具有该装置的自行车及电动自行车，属于自行车传动技术领域。
背景技术
现有的自行车和电动自行车的传动装置均为链条式传动，比如搭载后驱轮毂电机的电动自行车，其中轴与后驱轮毂电机之间通过链条(和链轮)传动连接，中轴的两端连接曲柄，曲柄端部连接脚踏。在实际应用时，电动模式下，后驱轮毂电机通电运行而直接带动后轮转动，使车辆前行；人力骑行模式下，骑行者踩踏脚踏，而通过曲柄带动中轴旋转，中轴在通过链条带动轮毂电机的外壳转动，电机外壳带动自行车后轮转动而使车辆前行。
上述这种链条式传动装置存在以下缺点：传动链条易断裂损坏，而且容易误伤使用者，同时容易污损使用者衣物，而且需要经常维护。因此，近年来已经采用轴传动代替普通的链条传动，轴传动具有结实牢靠免维护的特点，但传统的轴传动的传动轴两端一般使用深沟球轴承，而深沟球轴承直径与高度比大，增加了车架的尺寸与重量，且深沟球轴承的轴向与径向负载偏小，非常影响传动系统的使用寿命。
发明内容
本发明目的是针对现有技术存在的缺陷提供一种自行车传动装置和具有该装置的自行车和电动自行车。
本发明为实现上述目的，采用如下技术方案：一种自行车传动装置，包括五通管和后平叉，所述五通管内设置有传动输入轴，所述后平叉内设置有通过圆锥齿轮与所述传动输入轴配合连接的传动输出轴；所述传动输入轴的两端分别通过支撑轴承与对应设置在五通管两侧的五通管盖固定连接，且所述传动输入轴的两端分别与自行车脚蹬固定连接；所述传动输出轴分别通过套设的推力球轴承和滚针轴承与设置在所述五通管和后平叉之间的输出轴轴承安装座固定连接。
进一步优选的方案是，所述传动输入轴为五通轴。
进一步优选的方案是，所述传动输出轴由所述推力球轴承轴向限位，并由所述滚针轴承径向限位。
进一步优选的方案是，所述输出轴轴承安装座通过设置的键销与所述五通管和后平叉固定连接。
一种自行车，其包括上述的自行车传动装置。
一种电动自行车，其包括上述的自行车传动装置。
本发明的有益效果：本发明中采用推力球轴承和滚针轴承代替传统的深沟球轴承，由于推力球轴承的轴向负载大，滚针轴承的径向负载更大，且滚针轴承的体积更小，使得传动装置的整体结构更加紧凑，体积更小，使用寿命更长；并且上述结构的设置还使得车架用铝型材的尺寸结构更加小，不仅省了材料，还能留给别的部件更多的安装空间，进一步的使得零件的布局更宽松合理。
附图说明
图1为本发明的主视图结构示意图。
图2为本发明图1中A-A向结构示意图。
具体实施方式
图1、图2所示，涉及一种自行车传动装置，包括五通管3和后平叉7，所述五通管3内设置有传动输入轴1，所述后平叉7内设置有通过圆锥齿轮与所述传动输入轴1配合连接的传动输出轴4；所述传动输入轴1的两端分别通过支撑轴承5与对应设置在五通管3两侧的五通管盖6固定连接，且所述传动输入轴1的两端分别与自行车脚蹬(未图示)固定连接；所述传动输出轴4分别通过套设的推力球轴承9和滚针轴承10与设置在所述五通管3和后平叉7之间的输出轴轴承安装座8固定连接。
进一步优选的方案是，所述传动输入轴1为五通轴。
进一步优选的方案是，所述传动输出轴4由所述推力球轴承9轴向限位，并由所述滚针轴承10径向限位。
进一步优选的方案是，所述输出轴轴承安装座8通过设置的键销2与所述五通管3和后平叉7固定连接。
本发明的上述自行车传动装置不仅可以应用于自行车的传动装置中，还可以应用于电动自行车的传动装置中。
本发明中采用推力球轴承和滚针轴承代替传统的深沟球轴承，由于推力球轴承的轴向负载大，滚针轴承的径向负载更大，且滚针轴承的体积更小，使得传动装置的整体结构更加紧凑，体积更小，使用寿命更长；并且上述结构的设置还使得车架用铝型材的尺寸结构更加小，不仅省了材料，还能留给别的部件更多的安装空间，进一步的使得零件的布局更宽松合理。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
