摘要
钳盘式制动器拖磨实验台是对行车制动的机械的制动装置的性能进行测试的实验装置。
本文只要论述了该实验台的设计思想，设计方法及设计过程，并从理论上对该方案进行了论证。
在设计过程中，本文详细地阐述了各种元件的设计步骤及方法，以及对标准件的选择原则。传动系统中为了达到力矩要求采用了链传动，本文对链传动的优点缺点加以分析，并对链传动的性能加以计算说明。对轴的强度进行了校核。
制动过程中，转速变化很大，能量瞬时是一个主要问题，促使油温快速升高。在本次设计中，一方面采用恒功率变量泵来减小电机容量，另一方面在油箱中管路：回油处加上冷却器，来保持油温在一定温度范围内。同时考虑油液不能在太低温度下工作，加上加热器当环境温度过低时要打开加热器。
本文对钳盘式制动器的各个设计部分进行了详细的介绍，对其工作原理——液压、气压控制进行调研、考察。

ABSTRACT
The dish type system moves the machine drag along to whet the experiment to is to a car system too the mechanical a function for moving device that move proceeds the on trial device that test.
The asked to discuss primarily should the design experimenting too thought, designing the method and designing the process, combining form proceeded the argument to that project theoretically.
In design process, this text expatiated every kind of a design of piece step and methods in detail, and to the choice principle of the standard piece. Spread to move the system inside for attaining the dint request adopted the chain spreads to move, this ask to spread to the chain the dynamic advantage weakness takes into the analysis, and spread to the chain the dynamic function take into the calculation elucidation. Proceeded the school to the axial strength.
The system moves the process inside, turning to change soon very big, the moment of energy is a key problem, urging the oil to go up quickly. In this design, adopt on the other hand the power change the deal pump to let up the electrical engineering capacity, on the other hand take care of the road in fuel tank: Returning the oil pluses the water cooler, keep oil is within the scope of certain temperature. Considering at the same time oil liquid can’t under too the low temperature degree work, plus the heating apparatus be the environment temperature to want to open the heating apparatus over the low hour.
This text moves to the dish type system the each design part of the machine proceeded the detailed introduction, as to it’s work the principle —— liquid press, the barometric control proceeds the investigation, investigating.
Key words : Experiment the set, temperature the control, dint request
