Abstract

The invention relates to a vent valve type exhaust brake system. A throttle valve (6) is arranged in a vent valve sleeve (7) and sleeved with a vent valve reset spring (9) and an adjusting cap (10), the vent valve reset spring (9) and the adjusting cap (10) are installed in a brake valve end cover (11), and a hollow spherical connector (8) is installed between the brake valve end cover (11) and the vent valve sleeve (7) in a sleeved mode and sealed by a sealing gasket (12); an ECU (4) is connected with a drive valve (5), the drive valve (5) is connected with a control device (13) on a brake assembly (2), and the vent valve sleeve (7) on the brake assembly (2) is connected with an air cylinder cover (3). The vent valve type exhaust brake system is uniform in brake force, brake performance of the vent valve type exhaust brake system is the same as the brake performance of an engine vent valve, damage to an engine is not caused, and the vent valve type exhaust brake system is compact in structure and easy to achieve.

Description

technical field [0001] The invention belongs to the technical field of vehicle braking, and in particular relates to an exhaust valve type exhaust braking system. Background technique [0002] At present, there are two types of exhaust brakes commonly used in domestic vehicle engines. [0003] One is the exhaust pipe exhaust brake, which adopts the structural form of installing an exhaust butterfly valve in the exhaust pipeline. The advantage is that the structure is simple and easy to implement; the disadvantage is that the braking force is limited, which may damage the engine, especially for the exhaust. The door creates a reverse impact force. [0004] The other is engine exhaust valve exhaust braking. By adding an auxiliary opening mode to the exhaust valve, the exhaust valve is opened a small amount after receiving the braking signal, resulting in lax closing and forming the exhaust valve throttling effect And consume energy, the advantage of this method is that the ...
