To provide a trailer control valve and a trailer control system which improves consistency of braking between a tractor and a trailer, thereby improves safety of the vehicle.SOLUTION: A trailer control valve comprises: a relay piston 30 and a balance piston 50, with two end faces of the relay piston 30 being respectively in communication with a control port 42 and located in a brake cavity 10, with the balance piston 50 being connected to a bottom wall of a first chamber 31 via an over-run amount spring 55, and there being a space in communication with brake cavity 10 between the balance piston and a top wall of the first chamber 31; an adjusting piston 60 arranged in a second chamber 32 of the relay piston 30, extending into the first chamber 31 and directly facing a valve port 52 of the balance piston 50; and an over-run amount adjusting port 44 in communication with the second chamber 32, where as an air pressure at the over-run amount adjusting port 44 changes, the adjusting piston 60 is pushed to change a distance from the valve port 52, such that an air pressure over-run amount of an air outlet relative to the control port 42 changes.SELECTED DRAWING: Figure 1

    【課題】トラクタとトレーラとの制動の一致性を向上させ、車両の安全性を向上させる。【解決手段】中継ピストン30の両端面は、制御口42に連通しブレーキキャビティ10に位置し、バランスピストン50は、オーバーラン量バネ55を介して第1のチャンバー31の底壁に接続され、且つ第1のチャンバー31の頂壁との間に、ブレーキキャビティ10に連通するスペースが残されている中継ピストン30及びバランスピストン50と、中継ピストン30の第2のチャンバー32に設置され、第1のチャンバー31に突入してバランスピストン50の弁口52に正対する調整ピストン60と、オーバーラン量調整口44であって、第2のチャンバー32に連通し、オーバーラン量調整口44の気圧が変わるにつれて、調整ピストン60が押し動かされて弁口52との間の距離を変えて、排気口の制御口42に対する気圧オーバーラン量を変えるオーバーラン量調整口44とを含む。【選択図】図1
