Abstract

这是一种节能高效的电动车。其用可充电蓄电 池为电源，由数台大小功率不同的电动机驱动，每台 电动机有其各自的电路***和开关装置。当电动车 开始起动或上坡阻力大时，大小功率的电动机同时开 动，形成合力。当起动后惯性力增大，阻力相对减小 时，可只开动小功率电动机，但其作用于驱动轴的最 高转数应大于大功率电动机。这样可节省电能消耗， 从而延长电动车的连续行驶里程和时间。而且其成 本低，驾驶方便，无污染。

Description

本发明涉及一种电力驱动的陆地交通运载工具，是由数台电动机组合成可分为多级功率驱动的电动车。
目前人们使用的以燃油发动机驱动的汽车本身机械损失较大，能量利用率低，因此耗能高，而且污染环境。现有的电动车也是能量利用率低，耗电量较大，目前水平的蓄电池电能容量还无法维持较长时间的连续行驶，因此实用效果较差。
本发明的目的是提供一种新型的节省电能消耗，连续行驶里程更长且无污染的组合电动机分级功率驱动的电动车。
本发明的目的是这样实现的：以可充电的蓄电池为电源，用数台功率大小不同的组合电动机作为电动车的驱动动力。每台电动机有其各自的电路***和开关装置，采用并列的电动机开关踏板，可同时开关，也可分别开关。当同时启动这些电动机运转时产生合力，可输出的功率最大，形成最大的功率输出级。当只开动大功率电动机时形成较大的功率输出级，如只开动较小功率电动机则是最小的功率输出级。这样就使电动车构成多于电动机数量的多个功率输出级，根据行驶时阻力大小的不同采用相应的功率输出级。如当电动车起动加速时，数台电动机同时开动运转，形成最大功率输出级。加速后，随着惯性力增加，阻力相对减弱，这时电动机的功率输出级递减，最后只启动小功率电动机运转既可使电动车加速或保持匀速行驶。为使较小功率电动机输出的功率能够有效驱动行驶，其作用于驱动轴的最高转数高于相对较大功率的电动机。在电动机与驱动轴之间的离合器，可起到提高电动车的起动性和减少磨擦阻力，均衡车速等作用。
采用上述方案，可以使电动车充分利用惯性力，提高能量转换率，延长连续行驶时间和里程，减轻环境污染，而且制造成本低，驾驶方便。
下面结合附图进一步说明实施本发明的方法。
附图中，1、大功率电动机;2、小功率电动机;3、电动机开关并列踏板;4、离合器制动踏板;5、离合器;6、驱动轴;7、可充电蓄电池;8、充电器。
以电动车自带的充电器（8）可随时接通电源向可充电蓄电池（7）充电，行驶时以蓄电池为动力电源启动电动机。图中的大功率电动机（1）和小功率电动机（2）分别有各自的电路***和开关装置。电动机开关踏板（3）是将两台电动机的开关并列在一起，可同时踏动开通，也可分别踏动其中任何一个。当电动车开始起动、上坡等阻力较大的情况下，就可同时开通两台电动机，由两者的合力形成最大的功率输出级。当阻力减小如只需加速时，便可只踏动一个大功率电动机的开关踏板。当行驶达到一定速度后，只需保持匀速或慢加速时。便可只踏动小功率电动机的开关踏板。这样在小功率电动机作用于驱动轴（6）的转速快于大功率电动机的条件下，利用行驶中的惯性力，以较小的电能消耗取得更好的驱动效果。离合器制动踏板（4）是两台电动机与驱动轴之间的离合器（5）制动***的并列踏板，可同时制动两个离合器，也可分别制动。
