Abstract

The invention discloses an auxiliary braking system and an implementation method. The auxiliary braking system comprises an exhaust gas turbocharger (20). An air outlet (21) is connected with an engine air inlet pipeline (30) which is provided with a first airflow outlet (31) and a second airflow outlet (32). The first airflow outlet (31) is used for supplying air to an engine (100), the second airflow outlet (32) is connected with a first air storage tank (60) through a first one-way valve (40), and the first air storage tank (60) is connected with a second air storage tank (70) of the braking system. Part of compressed air which is turbocharged and can not be used by the engine is applied to the braking system, a new air source is provided for the braking system, waste of energy for an automobile is reduced, and therefore the whole performance of the automobile is optimized.

Description

technical field [0001] The invention relates to a vehicle braking system, in particular to an auxiliary braking system and a realization method. Background technique [0002] In the existing braking system, the air is pumped into the air storage tank through the air pump installed on the engine, and then the air storage tank has a gas pipe connected to the brake master cylinder under the brake pedal. When the brake is applied, the valve of the brake master cylinder is opened, and the compressed air can be input into the brake cylinder through the air pipe. In this braking method, the high pressure in the air storage tank is driven by the engine, which consumes a lot of power. In order to improve engine power and improve economy, engines, especially diesel engines, are mostly equipped with supercharging devices now. In a common exhaust gas turbocharger, the exhaust gas turbine pushes the end of the compressor to compress the intake air, increasing the density of the intake ...
