丰田小货车以及工具车上装用的液压感载比例阀,是一种构造简单、维修方便的制动稳定装置。本文主要谈谈它的构造与调整,以利于其推广和使用。一、构造与原理车辆制动时,在惯性力的作用下,前、后轴的垂直载荷将发生很大的变化,即前轴负荷变大,后轴负荷变小。制动愈是剧烈,这种现象愈是严重。此时,如前、后轮制动器的制动压力不能随前、后轴载荷的变化与按比例地分配,则后轮将由于垂直载荷的减小而使其与地面的附着力降低(前轮与之相反),从而后轮首先抱死。在侧向力的作用下,车辆可能发生危 Toyota pickup truck and the vehicle equipped with a hydraulic load-sensing proportional valve is a simple structure, easy maintenance brake stability device. This article mainly talks about its structure and adjustment, in order to facilitate their promotion and use. First, the structure and principle Vehicle braking, under the action of inertial force, the vertical load of the front and rear axle will change a lot, that is, the front axle load becomes larger and the rear axle load becomes smaller. The more severe braking, this phenomenon is more serious. At this moment, if the brake pressure of the front and rear brakes can not be distributed proportionally with the changes of the front and rear axle loads, the rear wheel will reduce its adhesion to the ground due to the decrease of the vertical load In contrast), so the rear wheel first lock. Under lateral forces, the vehicle may be at risk
