轮边减速桥,这个名词我想大家都不会陌生。相对于单减速器桥来说,由于轮边减速桥的承载能强,且又将驱动桥的主减速器的尺寸缩小,车桥与地面间隙增加,使其通过性更强,也带来了轮边减速桥的抢购风潮。
The term wheel reducer is familiar to all of us. Compared with the single reducer axle, due to the strong bearing capacity of the wheel reducer axle, and the reduction of the size of the main reducer of the drive axle, the gap between the axle and the ground is increased, which makes it more trafficable, and also brings a rush to buy the wheel reducer axle.
工作原理
working principle
一般来说。使用轮边减速器是为了进一步增加汽车的驱动力,以满足或修正整个传动系统驱动力的匹配。目前采用的轮边减速器,就是为满足整个传动系统匹配的需要,而增加的一套降速增扭的齿轮传动装置。
Generally speaking. The use of wheel reducer is to further increase the driving force of the car to meet or correct the matching of the driving force of the entire transmission system. At present, the wheel side reducer is an additional gear transmission device for speed reduction and torque increase to meet the matching needs of the entire transmission system.
从发动机经离合器、变速器和分动器把动力传递到前、后桥的主减速器,再从主减速器的输出端传递到轮边减速器及车轮,以驱动汽车行驶。在这一过程中,轮边减速器的工作原理就是把主减速器传递的转速和扭矩经由其降速增扭后,再传递到车轮,以便使车轮在地面附着力的反作用下,产生较大驱动力。
The power is transmitted from the engine to the main reducer of the front and rear axles through the clutch, transmission and transfer case, and then from the output end of the main reducer to the wheel reducer and wheels to drive the car. In this process, the working principle of the wheel side reducer is to transfer the speed and torque transmitted by the main reducer to the wheels after speed reduction and torque increase, so that the wheels can generate greater driving force under the reaction of the ground adhesion.
优点
advantage
1、通过性强
1. Strong trafficability
轮边减速器桥与单减速器桥比拟,轮边减速器桥要比单减速器桥的主减速器小,轮边减速器桥的离地间隙更大,所以其通过性更强。适合复杂路面。
Compared with the single reducer bridge, the wheel reducer bridge is smaller than the main reducer of the single reducer bridge, and the ground clearance of the wheel reducer bridge is larger, so its trafficability is stronger. Suitable for complex pavement.
2、驱动力强
2. Strong driving force
轮边减速器功用就是降速增扭,所以其扭矩大,驱动力强。适合爬坡。
The biggest function of wheel reducer is to reduce speed and increase torque, so it has large torque and strong driving force. Suitable for climbing.

缺点
shortcoming
1、结构复杂,传动率低
1. Complex structure, low transmission rate
轮边减速器的结构复杂,传导件较多,这使得传动率下降,能量损失加大。复杂的结构让维修保养也更加麻烦。
First of all, the structure of the wheel reducer is complex, and there are many conductive parts, which reduces the transmission rate and increases the energy loss. The complex structure makes maintenance more difficult.
2、装配技术要求高
2. High technical requirements for assembly
轮边减速器在装配的过程中要求严格,假如各部门零部件的配合尺寸泛起较大偏差,易导致轮边减速器的可靠性下降,同时因为国产制动鼓的材料及成本问题,国产车中轮边减速器散热效果仍是不很理想。
The wheel reducer is strictly required in the assembly process. If there is a large deviation in the matching size of the parts of various departments, it is easy to reduce the reliability of the wheel reducer. At the same time, because of the material and cost problems of the domestic brake drum, the heat dissipation effect of the wheel reducer in domestic vehicles is still not ideal.
