汽车轮毂轴承单元试验机

Testing machine for truck wheel hub bearing unit

轮毂是连接车轮和车轴的部分,是轮胎和车轴之间承受负荷的旋转组件,担负着承载车重、传递动力、轮胎散热等功能,而且作为一个旋转运动部件,轮毂在具有一定的刚度前提下,必须符合轻质、耐疲劳、动平衡等条件。轮毂加载试验机通过对轮毂内部轴承的轴向双向加载和径向单向加载,模拟轮毂在工作中的实际工况,并且对试验轴承温度、加速度、转速、时间等数据进行自动测量、记录及处理。

Wheel hub is the parts connecting to the wheel and axle, is rotating components under load between the tyre and axle, bearing the function of loading vehicle weight, the transmission power, tire heat dissipation, etc., and as a rotating parts, on the premise of a certain stiffness, wheel hub must meet conditions such as light weight, fatigue, dynamic balance,etc. Through the wheel hub inner bearing axial hi-directional loading and radial one-way loading, wheel hub loading testing machine simulates the actual working condition of wheel hub at work, and measures, records and processes automatically the test data of temperature, acceleration, speed, time ,etc of tested bearings.
