Description

马达驱动的车辆、特别是双轮车
技术领域
本发明涉及一种马达驱动的车辆、特别是双轮车，其具有底盘、包括驱动单元和座位支架的中央单元、带有转向装置和操作单元的驾驶系统结构和轮架，所述轮架具有在后轮架和前轮架上被引导的前车轮和后车轮。
背景技术
紧凑的、重量相对轻的马达驱动的车辆由于高的交通往来以及与此相关的堵车风险而遍布在特别是市内交通中，然而也越来越多地能够灵活地使用在旅行中。特别是存在对可折叠成能携带的单元的双轮车的大量需求，所述双轮车应该在重量和尺寸方面是容易操纵和携带的。
发明内容
本发明的任务在于，提供一种用于这种马达驱动的车辆、特别是双轮车的在结构方面并且尤其在重量方面的新方案，所述马达驱动的车辆与市场中的供应商品相比带来显著的改进。
本发明通过如下方式解决所提及的问题，所述双轮车的在轮架上被引导的车轮无轮毂地借助于滚动轴承通过环形的车轮轴承法兰悬置在同样环形地能固定在轮辋上的车轮轴承法兰上。
这种结构与具有轮毂轮的已知结构相比的极大优点在于，通过车轮的无轮毂的结构可以显著地节省重量，并且通过将用于车轮悬置的铰接点布设在车轮与路面的接触点附近实现了弹入和弹出减震的优点。此外，这种结构在这种重量轻的车辆中具有的优点是，通过车轮微小的无弹性的质量明显改善行驶舒适性和行车稳定性。
特别有利地实现根据本发明的解决方案，其中，扭转弹性的弹簧元件通过固定凸缘布置在车轮轴承法兰上，所述弹簧元件优选地由与固定凸缘(一体地或刚性锁合地)连接的元件壳体构成，将至少一个、优选地在元件壳体的大致正方形的基本形状的情况下为四个均匀分布地布置的、棒状地构造的扭转弹性的弹簧元件张紧地置入所述元件壳体中。这个或这些弹簧元件可以在本发明对象的优选的实施方式中借助于基本上棒状的弹性减震核心元件张紧地布置在元件壳体中。通过弹性减震核心元件可以借助于布置在朝向轮架的一侧上的固定凸缘将弹簧元件固定在轮架上。
通过棒状的弹性减震核心元件相对车轮轴承法兰的布置(用于将固定凸缘固定在车轮轴承上的弹性减震核心元件与中心的距离＝用于使车轮弹入减震的杠杆臂)并且结合弹簧元件的弹性比和尺寸能够选择或者调节阻尼或弹性减震。
根据本发明的解决方案视为特别有利的，其中，能转向的前车轮借助于固定在环形的轮辋侧的车轮轴承法兰上的承载元件与能通过所述转向装置转向的轮架连接，以使得理论的转向轴线延伸穿过理论的车轮中心。利用这种结构在无极大耗费的情况下实现，在无轮毂的能转向的车轮中能够如同由轮毂支承的转向车轮那样以传统的方式进行转弯运动。
在根据本发明的车辆中，环形的制动元件可以作为制动盘与轮辋连接，所述制动元件基本上以传统的方式与能固定在轮架上的制动块共同作用。
被驱动的后车轮可以具有固定在轮辋侧的环形的驱动元件，所述驱动元件能够通过驱动单元直接或间接地驱动。优选地，在轮辋侧的驱动元件的驱动通过对振动的后车轮运动进行补偿的传动结构实现。
根据对于本发明的对象特别优选的驱动解决方案，轮辋侧的驱动元件是齿轮圈，所述齿轮圈能够通过齿形皮带驱动。然而轮辋侧的驱动元件也可以构造为环形的链轮齿圈，所述链轮齿圈通过链条由驱动单元驱动。
结合本发明的优点可以特别是在根据实施成轻便摩托车类型的双轮车的情况下实现。由于重量优点，根据本发明的结构尤其适合于可折叠的双轮车，其中，通过特定的车轮结构实现小的重量为这种车辆的纯电驱动装置提供理想的前提条件。
为了可以全面地利用重量优点提出，这种车辆的主要构件、例如底盘、用于容纳驱动装置的中央单元、驾驶系统结构以及轮架构造为纤维复合结构。
附图说明
根据本发明构造的马达驱动的双轮车在附图中示出。下面根据所述实施例及其细节应该详细地说明本发明对象的特征和细节。
附图中：
图1以侧视图示出根据本发明的马达驱动的车辆；
图2示出根据本发明的具有前轮架的马达驱动的双轮车的无轮毂的前车轮；
图3示出根据本发明的具有驱动单元和制动环的车辆的无轮毂的后车轮；
图4示出扭转弹性的弹簧元件在轮架上(前车轮)的布置。
具体实施方式
马达驱动的双轮车1由底盘2、中央单元3以及驾驶系统结构8构成，所述中央单元在所述实施例中包括驱动单元4和(因为构造为电动车)电池箱5、具有驾驶员座位7的座位支架6，所述驾驶系统结构包括具有转向杆9的转向装置和操作单元。此外，后轮架10和前轮架11铰接在底盘2上。在所示的实施例中，出于重量原因将后轮架10和前轮架11构造为单臂结构。然而无问题地可以考虑的是，不仅后轮架而且前轮架(或者必要时这两个轮架中的仅仅一个轮架)可以构造为与车轮叉状地搭接。
后车轮12和前车轮13构造为无轮毂的结构(原理构造中的结构也公知为佛朗哥·斯伯勒无心轮“Franco-Sbarro-Orbitalrad”)。在所述实施例中通过环形地固定在轮辋14或15上的车轮轴承法兰20或22(未详细示出)实现车轮支承。车轮轴承法兰20、22是本身由汽车制造和/或机械制造公知为滚动轴承(球、滚子、滚针)所已知的轴承结构的一部分。在此，滚动轴承的环形件的一个环形件安置在轮辋上并且随着轮辋旋转，并且第二环形件不动地固定在轮架10或11上。在支承方面，用于后车轮支承装置和前车轮支承装置的结构细节完全或者至少在很大程度上一致。
布置在轮辋上的制动环16或17同样在后车轮12上或者在前车轮13上很大程度上在结构上是一致的，制动环与固定在轮架10或11上的制动块(未示出)共同作用。制动块的结构基本上相应于当前的现有技术。
图2详细地示出具有固定在其上的实际的车轮轴承18的前单臂轮架11，所述车轮轴承承载滚动轴承的环形的车轮轴承法兰，该车轮轴承法兰通过滚动轴承元件与同样环形的、固定在轮辋上的用于实际的车轮支承的第二车轮轴承法兰22共同作用。为了能够使具有这种无轮毂的车轮结构的双轮车进行常规的转向，假想的线X＝转向直拉杆19的轴线延伸穿过前车轮13中的同样为理论的中心Z。
图3示出被驱动的后轮辋14(无轮胎地示出)。车轮轴承法兰20固定在轮辋14上，所述车轮轴承法兰通过与其共同作用的滚动轴承元件与对应的固定在后轮架10(图1)上的车轮轴承法兰共同作用。
制动环16和具有外齿部的环形的齿轮圈21同样固定在轮辋14上，通过所述齿轮圈借助于齿形皮带(未示出)例如通过驱动单元4的小齿轮23实现驱动后车轮。后车轮12的振动的、弹入和弹出的车轮运动可以通过皮带张紧器24补偿。
在图2、3和4中示意性地示出弹性减震或阻尼结构，所述弹性减震或阻尼结构应该使用在本发明的对象中：车轮轴承法兰20、22通过刚性地固定在其上的固定凸缘25、26承载元件壳体29、30，该元件壳体优选地与固定凸缘25、26一体地连接、容纳至少一个扭转弹性的弹簧元件27、28、大致以正方形的基本形状构造。在所示的实施例中，借助于同样基本上棒状地构造的、在很大程度上刚性的、例如由钢构成的弹性减震核心元件31在所述元件壳体29、30中均匀地在正方形的角部上在张紧的情况下布置四个弹簧元件27。在朝向轮架10、11的一侧上，弹性减震核心元件31通过固定凸缘(未示出)固定在轮架10、11上。通过弹簧元件27的预紧或减小的或增大的张紧和具有弹性减震核心元件31的元件壳体29实现了在车轮相对轮架11相对运动时基于作用到扭转弹性的弹簧元件上的扭力进行弹性减震或阻尼。通过弹性减震核心元件31相对车轮轴承法兰22的布置并且结合弹簧元件27的弹性比和尺寸能够选择或者调节车轮的阻尼或减震。
对于本领域技术人员可容易实行的是，考虑不仅用于驱动而且用于车轮悬置的不同的结构上的解决方案和弹性减震解决方案，而由此不脱离本发明的基本构思。
