卡钳体/壳体

Structural housing component of disc brake calipers that contains pistons and brake pads.

技术定义与适配语境
典型 卡钳体/壳体 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。

The caliper body/housing is the primary structural component in a disc brake system that mounts over the brake rotor. It serves as a rigid frame containing hydraulic pistons, brake pads, and fluid passages. During braking, hydraulic pressure forces pistons against the inner brake pad, while the caliper body slides or flexes to apply equal force to the outer pad, creating clamping force on the rotor.

定义
The caliper body/housing is the primary structural component in a disc brake system that mounts over the brake rotor. It serves as a rigid frame containing hydraulic pistons, brake pads, and fluid passages. During braking, hydraulic pressure forces pistons against the inner brake pad, while the caliper body slides or flexes to apply equal force to the outer pad, creating clamping force on the rotor.
工作原理
Converts hydraulic pressure from the master cylinder into mechanical clamping force through piston movement. The caliper body acts as a reaction frame: hydraulic pressure pushes pistons against the inner brake pad, while the caliper body either slides on guide pins (floating caliper) or flexes (fixed caliper) to apply equal force to the outer pad, sandwiching the rotor between pads.
材料
Typically gray cast iron (GCI) or aluminum alloy (A356-T6). High-performance applications may use forged aluminum or ductile iron. Materials must withstand thermal cycling (up to 300°C)corrosionand mechanical stresses.

常见问题

What is the difference between floating and fixed caliper bodies?

Floating caliper bodies slide on guide pins to apply pressure, while fixed caliper bodies are rigidly mounted and use pistons on both sides of the rotor for more even pressure distribution and better performance.

Why are caliper bodies typically made from cast iron or aluminum?

Cast iron provides excellent durability and heat dissipation, while aluminum reduces weight and improves corrosion resistance, making it common in modern vehicles for better fuel efficiency.
