A brief introduction of universal joint.

The so-called universal joint, it refers a mechanical structure,which use spherical connection to achieve the different coaxial transmission of power, and it is a very important component in a car.

Universal joint, called the universal combined with transmission device. In front of a rear wheel drive car engine, transmission device installed in the transmission of universal output shaft and axles Lord reducer between input shaft; And lead the engine of the car front wheel drive shaft that is omitted, gimbal installed in both responsible for driving and be responsible for steering the front axle half shaft between with wheels.

According to the apparent elasticity in the reverse direction,universal can be divided into rigid Universal joint and flexible Universal joint. Rigid Universal joint can divide again unconstant velocity joins(the commonly used is a cross universal joint), quasi rzeppa constant velocity joins (such as thermodynamic type Universal joint) and patterned constant speed universal (such as ball cage type Universal joint).http://www.seekpart.com/power-transmission/universal-joints/A+cross+universal+joint.html
