Abstract

The application relates to a brake rocker arm, which includes a shaft seat, and the shaft seat is provided with an oil drain mechanism and a pressing mechanism, and the oil drain assembly includes an oil drain seat and a conduction assembly, and the oil drain seat and the shaft seat connected, the oil drain seat is provided with an oil drain cavity, the conduction assembly is located in the oil drain cavity and can slide in the oil drain cavity, the press-down mechanism includes a press-down seat and a press-down assembly, and the press-down A lower pressure chamber is provided on the seat, the lower pressure seat is connected with the oil drain seat, the lower pressure assembly is located in the lower pressure chamber and can slide in the lower pressure chamber, the oil drain chamber and The shaft seat is communicated with through the first flow channel, and the oil drain chamber is communicated with the down pressure chamber through the second flow channel. The application has the effect of reducing the volume and weight of the engine valve train.

Description

technical field [0001] The present application relates to the field of rocker arms used in valve train assemblies, in particular to a brake rocker arm. Background technique [0002] In addition to wheel brakes, compression engine brakes can be used, for example, as auxiliary brakes on relatively large vehicles (eg trucks) powered by heavy or medium duty diesel engines. When activated, the compression engine braking system is arranged to provide an additional opening for the exhaust valve of an engine cylinder to allow compressed air to pass through the exhaust valve of the engine cylinder as the piston approaches the top dead center position of that cylinder of the engine. Air valve released. This makes the engine act as an energy-hungry air compressor slowing the vehicle down. [0003] Existing vented engine brakes are generally independent, and are installed above the engine valve train through one or more brake housings. [0004] With regard to the related technologies...
