Description

一种齿轮传动液压调速的无极变速器
技术领域
本发明涉及传动装置技术领域,具体涉及一种齿轮传动液压调速的无极变速器。
背景技术
现有的无极变速器可分为两大类:静液压无极变速器、机械式无极变速器。
静液压无极变速器具有调速范围大、易操作、且实现自动化、使用寿命长,但制造精度要求高,滑动率较大、运转时容易发生漏油,所以传动效率相对机械式无极变速器较低,这也是为什么普通车辆一直没有用静液压无极变速器的原因。
机械式无极变速器,由于现在车用无极变速器都采用摩擦式传动方式,所以承载能力较低、抗过载及耐冲击性较差、摩擦件使用寿命较短,其传动效率较静液压无极变速器较高,但是相对于齿轮传动效率较低。
发明内容
本发明的目的是提供一种齿轮传动液压调速的无极变速器,它结合液压和齿轮的特点,避免了静液压无极变速器、机械式无极变速器的弊端,具有传动效率高、易实现自动化、使用寿命高、成本低、体积小的特点。
为了解决背景技术所存在的问题,本发明是采用以下技术方案:它包含主动差速器、被动差速器、第一定量液压泵、第二定量液压泵、流量分配阀、出油管、进油管,所述主动差速器的右侧输出轴上固定有第一输出齿轮,主动差速器的左侧输出轴上固定有第二输出齿轮,主动差速器两侧的输出轴分别连接在第一定量液压泵、第二定量液压泵上,第一定量液压泵、第二定量液压泵的上端通过进油管连接到流量分配阀出油端,第一定量液压泵、第二定量液压泵外侧均通过出油管连接到流量分配阀进油端,主动差速器的旋转外壳上有齿轮,且上端啮合有第一输入齿轮,被动差速器右侧输入轴上固定有第一从动齿轮且与第一输出齿轮啮合,被动差速器左侧输入轴上固定有第二从动齿轮且与传导齿轮啮合,第二输出齿轮也与传导齿轮啮合,被动差速器的旋转外壳上也设有齿轮且与第二输出齿轮啮合。
本发明工作原理:输入齿轮13驱动主差速器外壳旋转,从而带动两侧输出轴旋转,然后通过各个齿轮啮合,从而带动被动差速器2的两侧输入轴旋转,但被动差速器2的两侧输入轴旋转方向是相反的,所以被动差速器2的旋转外壳向着转速较快的一根输入轴相同的方向旋转,外壳旋转的速度和两根输入轴转速差成正比,当两轴转数相等时,则外壳不旋转,由于输出齿轮14与被动差速器2旋转外壳啮合,所以能量最终会通过齿轮14传递出去,流量分配阀的作用就是通过流通截面积的分配,来控制两个定量液压泵的转速差,从而控制被动差速器2的两根输入轴的转速差,因此可达到控制输出齿轮转速的目的,在整个能量传递过程中能量先从主动差速器分流,而后又在被动差速器合流,所以整体功率不会发生改变,因此变速的同时,扭矩也会发生相应的改变,本发明中,液压系统中,液压油本身不参与传动,只负责主动差速器两侧的输出轴的能量分配,所以液压系统本身消耗的能量较少。
本发明具有以下有益效果:它结合液压和齿轮的特点,避免了静液压无极变速器、机械式无极变速器的弊端,具有传动效率高、易实现自动化、使用寿命高、成本低、体积小的特点。

本具体实施方式工作原理:输入齿轮13驱动主差速器外壳旋转,从而带动两侧输出轴旋转,然后通过各个齿轮啮合,从而带动被动差速器2的两侧输入轴旋转,但被动差速器2的两侧输入轴旋转方向是相反的,所以被动差速器2的旋转外壳向着转速较快一根输入轴相同的方向旋转,外壳旋转的速度和两根输入轴转速差成正比,当两轴转数相等时,则外壳不旋转,由于输出齿轮14与被动差速器2旋转外壳啮合,所以能量最终会通过齿轮14传递出去,流量分配阀的作用就是通过流通截面积的分配,来控制两个定量液压泵的转速差,从而控制被动差速器2的两根输入轴的转速差,因此可达到控制输出齿轮转速的目的,在整个能量传递过程中能量先从主动差速器分流,而后又在被动差速器合流,所以整体功率不会发生改变,因此变速的同时,扭矩也会发生相应的改变,本发明中,液压系统中,液压油本身不参与传动,只负责能量分配,所以液压系统本身消耗的能量较少。
本具体实施方式具有以下有益效果:它结合液压和齿轮的特点,避免了静液压无极变速器、机械式无极变速器的弊端,具有传动效率高、易实现自动化、使用寿命高、成本低、体积小的特点。
