The utility model relates to a wheel-side supporting shaft of a driving axle. In order to solve the shortcomings of high processing cost and poor versatility of the existing wheel-side supporting shaft of an integral driving axle, the utility model constructs a combined wheel-side supporting shaft of a driving axle, which is successively provided with a locking nut installation position and an internal gear spline connection position from left to right on the supporting shaft. The bearing position, the oil seal position and the connecting disc are separated, and the supporting shaft is composed of the main body of the supporting shaft and the connecting disc. The locking nut installation position, the spline connection position of the internal gear, the bearing position and the oil seal position are arranged on the main body of the supporting shaft, and the connecting disc is fixed on the right end surface of the main body of the supporting shaft through bolts. In the utility model, the supporting shaft is a split structure, and the main body of the supporting shaft and the connecting disc can be manufactured separately, which reduces the manufacturing cost. The modular and serialized design of the driving axle with different braking modes and different loads is realized through different combinations of the main body of the supporting shaft and the connecting disc.

驱动桥组合式轮边支承轴及驱动桥
本技术涉及一种轮边支承轴,更具体地说,涉及一种驱动桥组合式轮边支承轴及驱动桥。
技术介绍
现有的驱动桥轮边支承轴为一体结构,如图1所示,其从左至右设置有锁紧螺母安装位、内齿轮花键联接位、轴承位、油封位、联接盘等。对于湿式制动的驱动桥,联接盘一般是通过螺栓与湿式制动器及湿式桥壳联接的;对于干式制动的驱动桥,联接盘一般是通过焊接与干式桥壳联接,通过螺栓与干式制动器联接的。根据不同载荷要求,其轴承位、内齿轮花键联接位、锁紧螺母安装位的尺寸设计不同。目前整体式的驱动桥轮边支承轴的加工先经锻造形成毛坯,再进行精加工。对于湿式桥轮边支承轴,联接盘外径是轴承位外径的3至4倍,锻造工艺性差,材料有效利用率低,成本高。产品系列化开发时,由于联接盘的联接方式不同,或载荷不同,需要设计开发多种不同的轮边支承轴,其通用性差,种类繁多。
技术实现思路
本技术要解决的技术问题是现有整体式驱动桥轮边支承轴加工成本高、通用性差的缺点,而提供一种便于加工、部件通用性高的驱动桥组合式轮边支承轴以及使用该轮边支承轴的驱动桥。本技术为实现其目的的技术方案是这样的:构造一种驱动桥组合式轮边支承轴,在所述支承轴上从左至右依次设置有锁紧螺母安装位、内齿轮花键联接位、轴承位、油封位、联接盘;其特征在于所述支承轴为分体式结构,其主要由支承轴主体和所述联接盘构成,所述锁紧螺母安装位、内齿轮花键联接位、轴承位、油封位设置在所述支承轴主体上,所述联接盘通过螺栓固定在所述支承轴主体的右端面上。在本技术中,支承轴为分体式结构,支承轴主体和所述联接盘可以分开加工制造,降低了制造成本,通过支承轴 ...
