Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of camshaft driver connection structures, in particular to a connection structure between a signal disk and a driver. Background Art
[0002] Variable valve timing systems are widely used in new automotive engines, increasing engine power and torque while reducing fuel consumption and exhaust emissions. In traditional engines, the connection between the camshaft, timing gear, and crankshaft is fixed, meaning the valve timing is fixed. Variable valve timing systems adjust the valve opening moment relative to the crankshaft angle within a certain range, optimizing the valve timing and achieving the goals of increasing engine power and torque while reducing fuel consumption and exhaust emissions. The driver is a key component of the variable valve timing system, creating a movable connection between the camshaft and timing gear that can rotate within a certain angle. The driver then uses the engine controller, oil control valve, and sensor to control the dynamic angle in a closed-loop manner, enabling intelligent adjustment of the valve timing.
[0003] Currently, the traditional riveting method between the driver and the signal disc has low strength. The signal disc, rivets, and rotor are in a simple fixed structure. During the driver installation process, facing the huge torque of the OCV valve, the signal disc often suffers from problems such as falling off, shifting, and deformation, which in turn leads to poor signal sensing and overall failure of the timing system, bringing huge difficulties to product research and development.
[0004] Therefore, the purpose of the present invention is to provide a connection structure between a signal disk and a driver to solve the above-mentioned existing problems. Utility Model Content
