前轴是转向桥的重要组成部份,位于转向桥的中部,其断面为工字形结构,故也称为工字梁。它承受车重、横向的反作用力和它们所引起的弯曲力矩,以及在制动时产生的制动力和制动力矩,是汽车上的安全部件之一。 国产中、重型汽车,都是用优质中碳钢锻造前轴,但在市场上经常出现铸造前轴,这种产品因其材质机械性能差,存在使轴断裂,造成行车事故,危及人身、财产安全的潜藏祸患。
The front axle is an important part of the steering axle, located in the middle of the steering bridge, the cross-section of the I-shaped structure, it is also known as I-beam. It is subject to vehicle weight, lateral reaction and the bending moment they cause, as well as braking and braking torque generated during braking, is one of the safety components on the car. Made in the medium and heavy vehicles, are made of high quality carbon steel forging the front axle, but in the market often appear casting front axle, because of its poor mechanical properties of the material, there is the shaft rupture, resulting in traffic accidents, endangering people, property Safe hidden dangers.
