Abstract

The invention discloses an automobile valve rocker embedded with tension pulleys. The automobile valve rocker comprises a rocker body. A shaft pedestal is arranged in the center of the rocker body. A shaft sleeve hole is formed in the shaft pedestal. Rocker rods are arranged at the two ends of the rocker body. The upper end of the shaft pedestal and each end of the rocker body are each provided with a reinforcing rib shaft rod, and the reinforcing rib shaft rods are guided into the front end faces and the rear end faces of the rocker rods. Tension pulley bodies are arranged on the reinforcing rib shaft rods, and the pulley surfaces of the tension pulley bodies are sleeved with a tension steel wire rope. In this way, the compressive strength of the valve rocker can be improved through the tension pulley bodies installed on the valve rocker in the embedded mode, the situation that deformation and fracture occur when the valve rock bears high stress is avoided, and the service life of the valve rocker is prolonged.

Description

technical field [0001] The invention relates to the field of automobile castings, in particular to an automobile valve rocker embedded in a tension pulley. Background technique [0002] The valve rocker arm is an automobile valve part that cooperates with the camshaft to open the door in a timely manner to complete the intake and exhaust of the engine. It is an important part of the valve control system. The shaft hole is used for assembling the rocker arm shaft, and an intake and exhaust valve rocker arm are respectively installed at both ends of the shaft. A decompression shaft is also installed on the rocker arm of the valve, which is used to reduce the pressure in the cylinder and facilitate the starting of the gasoline and diesel engines. The traditional valve rocker arm is cast in one piece, lacks corresponding protection devices to protect the valve rocker arm and improve its stability, and the valve rocker arm is easily broken when it is used for a long time or subj...
