本文阐述了总重在9吨以上的载重汽车的盘式制动器的发展概况,研究了重型汽车的盘式制动器的性能,并与现有制动器的性能进行了比较。在此基础上,本文作者认为重型汽车的盘式制动器将迅速发展。就经验而言,载重汽车的制动系统一般应满足二个基本要求。其一是,在干路面上行驶的满载车辆制动时,其后轮制动力矩足以使后轮在路面上滑移;其二是,在湿路面上行驶的空载车辆制动时,其前轮制动力矩不足以使前轮在路面上滑移。上述要求使制动力平衡,前 This article presents an overview of the development of disc brakes for trucks weighing more than 9 tons. The performance of disc brakes for heavy vehicles is studied and compared with the performance of existing brakes. On this basis, the author of the paper believes that the disc brake of heavy vehicles will develop rapidly. As a rule of thumb, the brake system of a truck usually meets two basic requirements. One is that when braking a fully loaded vehicle running on a dry road surface, the rear wheel braking torque is sufficient to cause the rear wheel to slip on the road surface; and second, when a no-load vehicle traveling on a wet road surface is braked, Front wheel braking torque is not enough to make the front wheel slip on the road. The above requirements make the braking force balance, before
