Description

履带车辆的无级变速转向机构 技术领域
本发明涉及履带车辆转向技术领域，特别涉及一种履带车辆的无级变速转向机构。
背景技术
履带车辆的转向不同于轮式车辆的转向，轮式车辆的转向只需要控制车轮角度转向即可，而目前采用的履带车辆的转向，基本都是通过刹车控制一侧的履带降速，而另一侧的履带正常运转来实现转向，但是，这种控制方式，当履带车辆高速行驶时，如果一侧的履带被刹停，容易造成翻车事故，危险系数高；而且，其通过人工制动控制，转弯精度低。
技术问题
本发明的目的：为了克服现有技术的缺陷，本发明提供了一种履带车辆的无级变速转向机构，其通过无级变速器连续精确地调整差速器左右半轴的转速，实现履带的精确转弯，提高了履带车辆高速行驶的安全性。
技术解决方案
本发明的技术方案：一种履带车辆的无级变速转向机构，其特征在于：包括有差速器、右传动轴、左传动轴以及用于调节右传动轴、左传动轴转速的无级变速器，差速器上连接有左半轴、右半轴，差速器的右半轴与右传动轴联动配合，右传动轴转动带动差速器的右半轴转动，差速器的左半轴与左传动轴联动配合，左传动轴转动带动差速器的左半轴转动，差速器的右半轴与右传动轴的转速比等于差速器的左半轴与左传动轴的转速比。
有益效果
采用上述技术方案，使用时，通过无级变速器控制右传动轴、左传动轴的转速，当右传动轴与左传动轴转速相等时，差速器的左半轴、右半轴转速也相等，履带车辆直行；当控制无级变速器使得右传动轴的转速相对于左传动轴变大时，差速器的右半轴转速也变大，从而使得履带车辆的右侧履带转速变大，这样可以实现履带车辆的左转弯；当控制无级变速器使得右传动轴的转速相对于左传动轴变小时，差速器的右半轴转速也变小，从而使得履带车辆的右侧履带转速变小，这样可以实现履带车辆的右转弯。因此，这种结构的无级变速转向机构，其通过无级变速器可以连续精确地调整差速器左、右半轴的转速，实现履带的精确转弯，提高了履带车辆高速行驶的安全性。
本发明的进一步设置：右传动轴上套设有第一右传动齿轮，差速器的右半轴上套设有第二右传动齿轮，第一右传动齿轮与第二右传动齿轮啮合形成差速器的右半轴与右传动轴的联动配合。
采用上述进一步设置，通过第一右传动齿轮与第二右传动齿轮啮合实现差速器的右半轴与右传动轴的联动配合，其结构简单，传动性能稳定，而且，可以通过改变第一右传动齿轮、第二右传动齿轮的齿数来调节右传动轴的转速，使用更加方便。
本发明的再进一步设置：左传动轴上套设有第一左传动齿轮，差速器的左半轴上套设有第二左传动齿轮，第一左传动齿轮与第二左传动齿轮啮合形成差速器的左半轴与左传动轴的联动配合。
采用上述再进一步设置，通过第一左传动齿轮与第二左传动齿轮啮合实现差速器的左半轴与左传动轴的联动配合，其结构简单，传动性能稳定，而且，可以通过改变第一左传动齿轮、第二左传动齿轮的齿数来调节左传动轴的转速，使用更加方便。

初始状态下，无级变速器 4 的两传动轮 41 、 42 转速相等即右传动轴 2 、左传动轴 3 的转速相等，这样差速器 1 的左半轴 5 、右半轴 6 转速也相等，此时，履带车辆直行；当控制无级变速器 4 使得右传动轴 2 的转速相对于左传动轴 3 变大时，差速器 1 的右半轴 6 转速也变大，从而使得履带车辆的右侧履带转速变大，这样可以实现履带车辆的左转弯；当控制无级变速器 4 使得右传动轴 2 的转速相对于左传动轴 3 变小时，差速器 1 的右半轴 6 转速也变小，从而使得履带车辆的右侧履带转速变小，这样可以实现履带车辆的右转弯。因此，这种结构的无级变速转向机构，其通过无级变速器 4 可以连续精确地调整差速器 1 左右半轴 6 的转速，实现履带的精确转弯，提高了履带车辆高速行驶的安全性。
