Abstract

The invention discloses a braking rocker arm and a control method thereof, comprising a rocker arm shaft, a braking rocker arm body is sleeved on the surface of the rocker arm shaft, a roller is movably connected to the right side of the braking rocker arm body, and the The bottom of the roller is provided with a cam, the left side of the brake rocker body is fixedly connected with a brake execution box, the top of the brake execution box is provided with a knob, and the bottom of the knob is fixedly connected with a threaded rod, and the thread The bottom of the rod penetrates into the inner cavity of the brake execution box and is movably connected with a pressing plate. The invention solves the problem by arranging an oil outlet shell, a rubber sealing plate, a return spring, a control block, an adjustment groove, a squeeze wheel, a pull rod, an exhaust pipe, a first check valve, an air inlet pipe, a second check valve and an oil outlet pipe. The existing brake rocker arm lubricating oil supply is small, the lubrication effect is poor, and the problem of low braking precision is easily caused.

Description

technical field [0001] The invention relates to the technical field of brake rocker arms, in particular to a brake rocker arm and a control method thereof. Background technique [0002] When the car is braking, in addition to friction braking, the engine can also be braked to ensure that the engine will not output power to the outside world. The engine braking is mostly realized by the brake rocker arm. Its working principle is that when the engine is in the compression stroke When approaching the top dead center, driven by the brake rocker arm, the exhaust valve is opened a small lift, the compressed high-pressure gas in the cylinder is quickly released, so that the pressure in the cylinder is rapidly reduced, so the engine will work in the next During the stroke, the engine will basically not do external work. Since the brake rocker arm needs to move through the rocker arm shaft to exhaust the engine during braking, it needs to be lubricated at all times. The existing brak...
