Abstract
The present disclosure provides a sensor for measuring cam and tappet contact force of an engine and a measuring method. The sensor comprises a force carrying element, a force transmission element, a piezoelectric element, a force bearing element, a tappet head and a guide woodruff key. Meanwhile, the present disclosure also provides a measuring method by using the sensor. The sensor is simple in mechanism and convenient to use and can realize the measurement of the cam tappet contact force in the normal direction, the tangential direction and the axial direction of the contact surface.
