【摘要】 为提高中、低档摩托车的制动安全性能，目前亟待开发一种经济实用、便于安装的防抱死控制装置及其检测系统。本论文首先分析了摩托车制动时车轮的受力及运动状况，建立防抱死控制的数学模型，推导了控制参数的计算公式；在分析盘式制动器设计计算方法的基础上，提出针对已知摩托车车型、盘式制动器参数及路面条件的情况下，防抱死控制器理想控制压力的计算公式。基于上述理论，针对防抱死控制器产品的定型设计，提出变螺距弹簧和防抱死控制器工作压力的设计计算方法，并编制了系列化设计软件。给出防抱死控制器检测实验台的整体结构示意图和控制系统原理图，对试验台机械系统进行了详细设计。模拟各种路面条件，使用CRAS软件测试防抱死控制器的动、静态输入输出压力，并进行控制器装车道路试验，实验均取得了预期效果。课题的研究成果已取得国家专利，目前已作为产品投入小批量生产。该控制器结构新颖、便于安装、性能价格比好，将具有广阔的市场前景。更多还原

【Abstract】 In order to improve brake capability of medium-price and low-price motorcycles, a kind of economical and practical Anti-Lock Brake System (ABS) and its testing system need to be researched and developed urgently at present. This paper narrated the principle of motorcycle anti-lock brake control, provided the calculating method of controlling parameter and derived a formula about the braking pressure and friction factor of real road conditions. A mechanical motorcycle anti-lock brake controller was contrived and the series-design theory was completed on the basis of this formula; the construction parameters and design of nonlinear-spring were also addressed. The construction of testing system was designed and controlling principle was narrated. The input and output pressure of the controller were tested statically and dynamically under high μ, mid μ and low u conditions and real road conditions in computer routing, the controller satisfied two goals: delay and reduce the peak of braking pressure and produce superior braking distance. This controller has three virtues: the novel construction, the convenient for installation and the competitive price. Now it is in a small batch production and it will have a brisk market prospect.更多还原
