Clutch master cylinder of automobile 1 Scope This document specifies the terms and definitions, technical requirements, and test methods of clutch master cylinder of automobile (hereinafter referred to as the "master cylinder"). This document is applicable to the clutch master cylinder of automobile. 2 Normative references The following documents contain provisions which, through reference in this text, constitute provisions of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. GB/T 10125 Corrosion tests in artificial atmospheres - Salt spray tests GB 12981 Motor vehicle brake fluids GB/T 41481 Road vehicles - Cleanliness of components and systems QC/T 307 Performance requirements and bench test methods of vacuum booster for automobile QC/T 1125 Automotive clutch terminology and definition 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 maximum stroke distance that the piston moves from its initial position to its limit position 3.2 initial pressure-building travel distance that the piston moves from its initial position to the position where the pressure of hydraulic chamber is 0.1MPa 3.3 ideal stroke distance that the piston moves from its initial position to the position where the channel (such as the center valve or compensating hole) between the storage chamber and the hydraulic chamber of the master cylinder begins to close 3.4 the point of initial assistant force downward turning point of the characteristic line under different air source pressures in the input-output characteristic curve of a master cylinder with assistance force 3.5 the point of maximal assistant force upward turning point of the characteristic line under different air source pressures in the input-output characteristic curve of a master cylinder with assistance force 4 Product classification Master cylinders are classified into three types by structural forms: Classes A, B and C. Class A is hydraulic master cylinder, as shown in Figure 1; Class B is air-assistant master cylinder, as shown in Figure 2; Class C is vacuum-assistant master cylinder, as shown in Figure 3.
