中科搅拌车常见的后桥的作用

目前市面上常见的轻量化搅拌车有上汽红岩,陕汽德龙M3000,重汽豪沃T5G,重汽豪瀚,重汽豪曼,其中,德龙,豪瀚,豪曼,都分153后桥和457后桥,来说说这两种后桥的区别。
At present, the common lightweight mixers on the market are SAIC Hongyan, Shaanxi Delong M3000, heavy duty HOWO t5g, heavy duty howan and heavy duty Howman. Among them, Delong, howan and Howman are divided into 153 rear axle and 457 rear axle. Let's talk about the difference between the two rear axles.
457后桥标载13吨,457桥加大了轴承,承载量还是一样的,没什么大的变化。按参数说153是东风10吨桥,457是13吨桥。而且457比153承载能力强,153桥是十吨桥,半轴螺丝八棵,传动轴六根丝;457桥是十三吨桥,半轴螺丝十棵,传动轴八根丝。
The standard load of 457 rear axle is 13 tons. The bearing capacity of 457 rear axle is the same, and there is no big change. According to the parameters, 153 is Dongfeng 10 ton bridge and 457 is 13 ton bridge. Moreover, the bearing capacity of 457 is stronger than that of 153. 153 bridge is a 10 ton bridge with eight half shaft screws and six transmission shafts; 457 bridge is a 13 ton bridge with ten half shaft screws and eight transmission shafts.
153桥,其被动齿轮分度圆直径为435mm,是当初东风引进的日产柴的技术,前桥5T,后桥10T,装在东风当初的153车型上,得名153桥。
153 axle, with a diameter of 435mm, is the technology of Nissan Diesel introduced by Dongfeng at the beginning. 5T front axle and 10t rear axle are installed on Dongfeng's original 153 model, which is named 153 axle.
 
457桥的457指的是减速器从动齿轮节圆直径为457mm,13吨中后桥。435、460、457、485、300等等这些数字,都代表了该车桥中间被动齿轮(也就是大家常说的盆齿)的节圆直径
457 axle 457 refers to the reducer driven gear pitch circle diameter of 457mm, 13T middle and rear axle. 435, 460, 457, 485, 300 and so on all represent the pitch circle diameter of the middle passive gear of the axle
后桥的作用是什么?
What is the function of the rear axle?
1、如果是前桥驱动的车辆,那么后桥就仅仅是随动桥而已,只起到承载的作用。
1. If the vehicle is driven by the front axle, then the rear axle is just a follow-up axle, which only plays the role of bearing.
2、如果前桥不是驱动桥,那么后桥就是驱动桥,这时候除了承载作用外还起到驱动和减速还有差速的作用。
2. If the front axle is not the drive axle, then the rear axle is the drive axle. At this time, it not only plays the role of bearing, but also plays the role of driving, deceleration and differential.
3、如果是四轮驱动的,一般在后桥前面还配有一个分动器,后桥分为整体桥和半桥,整体桥配非独立悬架,如钢板簧悬架,桥配独立悬架,如麦弗逊式悬架。
3. If it is four-wheel drive, it is generally equipped with a transfer case in front of the rear axle. The rear axle is divided into integral axle and half axle. The integral axle is equipped with non independent suspension, such as steel leaf spring suspension, and the axle is equipped with independent suspension, such as Macpherson suspension.
后桥技术参数
Technical parameters of rear axle
1.承载级别:是指后桥设计大承载质量,以吨表示如:6吨级,10吨级,11吨级。等级超过13吨级的在国内道路是禁止的。
1. Bearing level: it refers to the designed large bearing mass of the rear axle, expressed in tons, such as 6 tons, 10 tons and 11 tons. It is forbidden to use roads with a grade of more than 13 tons in China.
2.速比:是指用发动机的转速或者电机的转数除以减速机的输出转数,得出的数值就是减速机的速比。在出厂时车辆会注明这个数值,因为日后维修可能需要用到。
2. Speed ratio: it refers to the speed ratio of the reducer divided by the speed of the engine or the number of revolutions of the motor. This value will be indicated when the vehicle leaves the factory, because it may be needed for future maintenance.
