主缸活塞

Master cylinder piston converts mechanical force into hydraulic pressure in braking and actuation systems.

技术定义与适配语境
典型 主缸活塞 会按材料、尺寸公差、适配关系和失效风险在 汽车制造 中评估。

A precision cylindrical component within a master cylinder that moves under applied force to displace hydraulic fluid, creating pressure for actuating downstream mechanisms like brakes or clutches. It operates within a sealed bore and interfaces with seals to maintain fluid integrity while transmitting force.

定义
A precision cylindrical component within a master cylinder that moves under applied force to displace hydraulic fluid, creating pressure for actuating downstream mechanisms like brakes or clutches. It operates within a sealed bore and interfaces with seals to maintain fluid integrity while transmitting force.
工作原理
The piston translates linear mechanical input (e.g., from a pedal or lever) into hydraulic pressure by compressing fluid in the cylinder bore. This pressure is transmitted through hydraulic lines to actuate slave cylinders or other components, enabling force amplification and remote operation.
材料
Typically aluminum alloy (e.g.6061-T6) for lightweight applicationsor hardened steel (e.g.AISI 4140) for high-stress environments. May include surface treatments like anodizing or chrome plating for corrosion and wear resistance.
Weight
50-150 g
Diameter
19-25 mm
Stroke Length
20-40 mm
Surface Finish
Ra 0.4-0.8 μm
Operating Pressure
Up to 20 MPa
标准
ISO 4925DIN 74254
