Abstract

The exhaust valve braking equipment includes one exhaust valve, one rocking arm structure and one power set mounted on the cylinder head, and one cylinder head oil passage. The rocking arm structure provided with one oil passage communicated to the main engine oil passage and one oil sealing block includes one rocking arm seat with oil channel and oil hole, one rocking arm shaft with axial oil hole and radial oil hole communicated each other, one rocking arm with oil holes, and one piston couple mounted to the end of the rocking arm and provided with oil holes. The exhaust valve braking equipment keeps the exhaust valve opened to reduce the work produced by the gas in the combustor to the piston, reduce the rotation speed of the engine and raise the braking efficiency.

Description

(1) Technical field [0001] The invention relates to the technical field of engine exhaust braking for heavy vehicles, in particular to an exhaust valve braking device. (2) Background technology [0002] With the continuous increase of the load and weight of heavy trucks, the power of diesel engines is also increasing, and the braking power of the whole vehicle is increasingly insufficient. It is easy to fatigue, so it is particularly important to ensure that the vehicle has sufficient braking capacity and to increase the braking power of the vehicle. (3) Contents of the invention [0003] In order to solve the problems of insufficient braking power of the exhaust butterfly valve of heavy-duty vehicles and the fatigue of the driver in the prior art, the present invention provides a convenient and practical exhaust valve braking device that can increase the braking torque of the whole vehicle. [0004] The present invention is achieved through the following measures: an exh...
