The utility model discloses a disconnect type drive axle overall, including the left and right wheel assembly, the left and right side wheel assembly are respectively arranged on the surface of the left and right bearing seat, which is characterized in that the left and right bearing seat respectively with both ends of a beam connection, the the left and right side of the bearing seat are respectively arranged with the left and right wheel assembly of the left and right wheel drive shaft assembly is connected, the left and right side of the bearing seat is also provided with a left and right brake device. The utility model is disconnected the whole drive axle with non drive off the bridge and drive off the bridge advantages, can be applied to the twin rear wheel drive, both drive off the bridge, the quality of the spring comfort is good, but also have the non drive off the bridge the advantages of low cost, the technology of the rear wheel drive twin is a technical breakthrough. The open type integral drive axle can well meet the needs of passenger cars and trucks, especially the requirements of new energy vehicles.
【技术实现步骤摘要】
断开式整体驱动桥
本技术涉及汽车驱动桥领域,特别涉及一种兼顾汽车断开式传动和整体式驱动桥特点的断开式整体驱动桥。
技术介绍
汽车驱动桥的结构型式按工作特性分,可以归并为非断开式驱动桥和断开式驱动桥两大类。非断开式驱动桥,其半轴套管与主减速器壳均与轴壳刚性地相连一个整体梁,通过弹性元件与车架相连,因此簧下质量(即非簧载质量)比较大,当汽车在行驶过程中受到路面冲击而发生跳动或振动时,由于非簧载部件的质量较大,因此这些部件的振动能量也很大,从而使得车架以及由车架承载的车身部分剧烈振动,汽车行驶的平顺性、乘坐的舒适性大大降低。为了提高汽车行驶平顺性和通过性,有些轿车和越野汽车驱动轮均采用独立悬架断开式驱动,即将两侧的驱动轮分别用弹性悬架与车架相连,两轮可彼此独立地相对于车架上下跳动。与此相应,主减速器壳固定在车架上。驱动桥壳制成分段并通过铰接连接,这种称为断开式驱动桥。但采用独立悬架的断开式驱动桥一般适用于单胎,对于双胎由于现有独立悬架会引起磨胎等技术问题,因此双胎一般不采用独立悬架。总的来说,从性价比上,非断开式驱动桥,成本低,舒适性差。独立悬架的断开式驱动桥舒适性好,但成本高,对双胎后驱动不适用,也成为一个技术障碍。
技术实现思路
本技术的目的在于针对现有技术的上述不足和缺陷,提供一种断开式整体驱动桥,以解决上述问题。本技术所解决的技术问题可以采用以下技术方案来实现:断开式整体驱动桥,包括左、右轮边总成,所述左、右轮边总成的内侧面上分别设置有左、右承载座,其特征在于,所述左、右承载座分别与一横梁的两端连接,所述左、右承载座的内侧面还分别设置有一与所述左、右轮边总成连接 ...
