Description

液压传动汽车
技术领域
本实用新型涉及一种汽车，尤其是一种液压传动汽车。
背景技术
纵观世界各种汽车的传动结构，都是将发动机产生的高速扭矩通过离合器传给变速器，变速器经过传动轴传给驱动桥，经过驱动桥中的主减速器、差速器传递给半轴，由半轴带动车轮转动。而变速器、减速器、差速器都是由齿轮来传递扭矩的。由于一对齿轮的传动比是固定的，所以在要求必须有速比变化的场合只能采用增加齿轮的数量来完成。所以每辆汽车上都装有变速箱。但是，齿轮变速中的齿轮是有限的，所以它的速比也是有限的。近几年虽然在汽车上出现了自动变速和所谓的无级变速装置。但都是通过液压控制和电液压控制的自动换档控制系统来实现的。也就是说，它们还不是真正意义上的无级变速结构。
实用新型内容
本实用新型需要解决的技术问题是提供一种采用液压马达，操作简单、成本低廉、能真正实现无级变速的液压传动汽车。
为解决上述问题，本实用新型所采取的技术方案是：
一种液压传动汽车，包括车体、车轮、转向机构、装于车体上的离合器、油门、位于车体中与车轮连接的动力驱动装置，所述动力驱动装置包括通过管路连接的液压泵、液压马达、油箱、油量调节阀、离合器、倒车阀，其中油量调节阀与油门连接，液压马达安装在车轮上。
液压马达数量为二、四个中的一种，液压马达为为二个时，安装于两个后轮上或者两个前轮上，为四个时，安装在前后四个轮上。所述液压马达是液压叶片马达、液压齿轮马达中的一种。
所述液压泵是液压叶片泵、三螺杆液压泵中的一种。
采用上述技术方案所产生的有益效果在于：本新型汽车采用液压传动装置，代替传统的齿轮传动装置，由于没有了齿轮传动的变速箱，可实现真正的无级变速，解决解除了困扰司机多年的换档麻烦，能够在四个车轮上分别装上液压马达，实现四轮驱动或前、后轮相互切换驱动；由于结构简单、油量控制好调节，为今后发展成电脑控制提供了可行性，同时可以大幅度降低汽车的制造成本。
附图说明
图1是本新型的液压驱动原理图。
具体实施方式
下面结合附图对本实用新型做进一步详细描述：
如图1所示，为了实现真正意义上的无级变速，降低汽车的制造成本，本新型对汽车的传统齿轮传动进行了彻底的改革。将齿轮传动完全抛弃，改由液压传动装置驱动，其包括通过管路连接的液压泵18、液压马达15、油箱17、油量调节阀12、离合器11、倒车阀14，其中油量调节阀12与油门连接，液压马达15安装在车轮16上，其中液压马达可以是液压叶片马达或者液压齿轮马达，当然，也可以采用其他形式的液压马达，而采用液压叶片马达是最好的选择，所述液压泵是液压叶片泵或者三螺杆液压泵，当然，也可以采用其他形式的液压泵，而采用液压叶片泵是最好的选择。
其中液压马达15可以只装在后轮上，形成后轮驱动，也可以在两个前轮上分别安装两个液压马达，构成前轮驱动，或者在前后四个车轮上都安装液压马达，形成四轮驱动。
工作原理：由发动机10产生的扭矩，经过离合器11传给液压泵18，液压泵18产生的高压液压油通过输油管连接三通13，三通13一端的通往驱动车轮上的液压马达15，液压马达的输出轴带动车轮转动。在三通13的另一端装有一个可调节液压油油量的油量调节阀12，当需要减速时，慢慢地打开该油量调节阀12，一部分液压油就直接流到油箱17中，流向液压马达的油相对减少了，液压马达的转速自然就变慢了。反之，可以加快转速。因此，就可以获得连续的无级变速。在油量调节阀后边的油管上装一个倒车阀14(四通阀，市场上可以买到)，只要将四通阀的阀芯旋转90度，就可以改变液压油流进液压马达的进口位置，也就改变了马达的旋转方向，从而可改变汽车行进方向。
采用液压传动比采用齿轮传动有以下主要优点：
1、可以实现真正意义上的无级变速；
2、可以大幅度降低汽车的制造成本。
3、操作简单。只要控制油量调节阀(与普通汽车油门一样操作)，就可实现无级变速。解除了困扰司机多年的换档麻烦。
4、采用液压传动，由于结构简单、油量调节好控制，为今后发展成电脑控制提供了可能。
