To provide a hand braking unit that has an independent trailer brake function, satisfies the requirement of a driver for deceleration or braking of the trailer in the driving process, and improves the driving experience of an intelligent commercial vehicle.SOLUTION: A hand brake unit includes: a first control valve 20 of a trailer, which has a first passage and a second passage that are selectively opened; an air supply pipeline P1 of a main vehicle which connects an air source and a brake air chamber 15 of the main vehicle; an exhaust pipeline P4 of the main vehicle which selectively conducts the air supply pipeline of the main vehicle to connect the brake air chamber of the main vehicle and an exhaust port; and a cooperative control pipeline of the trailer which is connected to the air supply pipeline and the exhaust pipeline of the main vehicle to connect the brake air chamber of the trailer via the first passage. The hand brake unit further includes a second control valve 30 of the trailer, and the brake air chamber of the trailer is connected to the exhaust port via the second passage and the second control valve of the trailer to form the exhaust pipeline of the trailer.SELECTED DRAWING: Figure 1

    【課題】トレーラの独立ブレーキ機能を有し、運転者の走行中のトレーラの減速またはブレーキの需要を満たし、インテリジェント化商用車の運転体験を向上させる。【解決手段】ハンドブレーキユニットは、選一的に開放する第1の通路と第2の通路とを有するトレーラの第1の制御弁20と、空気源と主車のブレーキエア室15とを接続する主車の給気パイプラインP1と、主車の給気パイプラインとを選一的に導通して主車のブレーキエア室及び排気口を接続する主車の排気パイプラインP4と、主車の給気パイプライン及び主車の排気パイプラインに連通して第1の通路を介してトレーラのブレーキエア室を接続するトレーラの協同制御パイプラインとを含み、トレーラの第2の制御弁30をさらに含み、トレーラのブレーキエア室が第2の通路とトレーラの第2の制御弁を介して排気口を接続してトレーラの排気パイプラインを形成する。【選択図】図1
