Abstract

The invention provides a cam bearing block applied to a continuous variable valve lift driving device and relates to engine parts, solving the problem that an engine is high in cost and poor in economical efficiency by using an existing cam bearing block. The cam bearing block applied to a continuous variable valve lift driving device provided by the invention is arranged between a cam shaft and a driving part, and comprises a supporting part, a connecting part fixedly connected with the supporting part and a regulating center arranged on the connecting part; the supporting part is used for supporting the cam shaft; the connecting part is movably connected with the driving part at the regulating center to enable the driving part to rotate around the regulating center.

Description

technical field [0001] The present invention relates to engine components, and more particularly to cam bearing housings for variable valve lift drives. Background technique [0002] An engine equipped with a variable valve lift driving device can change the valve lift according to different working conditions of the engine, thereby improving the efficiency of the engine and reducing fuel consumption. [0003] The variable valve lift driving device usually includes a valve, a valve connecting rod connected to the valve, a valve rocker arm connected to the valve connecting rod, and a camshaft that drives the valve to open or close. There is a swing between the camshaft and the valve rocker arm. The swing arm is connected with a driving part, which is used to drive the swing arm to realize the change of the valve lift. [0004] A camshaft is a shaft that houses one or more cams, supported by cam bearing housings. In the variable valve lift driving device, the cam bearing sea...
