Novel brake rocker arm and control method thereof

Abstract

The invention discloses a novel brake rocker arm and a control method thereof. The novel brake rocker arm comprises a rocker arm shaft, wherein the surface of the rocker arm shaft is sleeved with a brake rocker arm body, the right side of the brake rocker arm body is movably connected with a roller, the bottom of the roller is provided with a cam, the left side of the brake rocker arm body is fixedly connected with a brake execution box, the top of the brake execution box is provided with a rotary knob, the bottom of the rotary knob is fixedly connected with a threaded rod, and the bottom of the threaded rod penetrates into an inner cavity of the brake execution box and is movably connected with a pressing plate. According to the brake rocker arm, by arranging an oil outlet shell, a rubber sealing plate, a reset spring, a control block, adjusting grooves, extrusion wheels, a pull rod, an exhaust pipe, a first one-way valve, an air inlet pipe, a second one-way valve and an oil outlet pipe, the problems that an existing brake rocker arm is small in lubricating oil supply amount and poor in lubricating effect, and low brake precision is likely to be caused are solved. The brake rocker arm has the advantages that the lubricating oil supply amount is large, the lubricating effect is good, and the brake rocker arm is worthy of popularization.

Description

Technical field [0001] The present invention relates to a brake rocker arm technical field, particularly to a novel braking rocker arm and its control method. Background technique [0002] When the car is braked, except through external friction brake can also be the engine brake, the engine does not guarantee in foreign power output, engine braking and more is achieved by braking rocker arm, its working principle is, when the engine is in the compression stroke near the top dead center, the driving in the braking rocker arm, the exhaust valve opening lift a small, quick release high pressure gas compressed in the cylinder, thereby rapidly reducing the pressure within the cylinder, and therefore the engine work in the following stroke, the engine will not substantially external work, the engine braking rocker arm due to the need to carry out the activities through exhaust rocker arm shaft during braking, it is necessary lubrication time, conventional self-lubricating effect is po...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of brake rocker arm and its control method, which has the advantages of large amount of lubricating oil supply, good lubrication effect on the brake rocker arm, and high braking precision, and solves the problem of the existing brake rocker arm lubricating oil supply. The amount of oil is small, the lubrication effect is poor, and it is easy to cause the problem of low braking precision
