Product Specifications

Technical details and manufacturing context for Actuator (e.g., Solenoid, Pneumatic Piston)

Definition
An actuator in brake/clutch assemblies is a critical component that receives control signals and generates precise mechanical movement to engage or disengage braking or clutching mechanisms. It serves as the interface between electronic/pneumatic control systems and the physical braking/clutching action, enabling automated or assisted operation of these safety-critical systems.
Working Principle
Actuators in brake/clutch systems operate by converting electrical energy (in solenoids) or pneumatic pressure (in pneumatic pistons) into linear or rotational mechanical motion. Solenoids use electromagnetic fields to move a plunger, while pneumatic pistons use compressed air to drive a piston rod. This motion is then transmitted to brake pads, clutch plates, or other engagement mechanisms to control vehicle deceleration or power transmission.
Common Materials
Stainless steel, Aluminum alloy, Engineering plastics, Copper windings
Technical Parameters
  • Stroke length - the distance the actuator can move from fully retracted to fully extended position (mm) Standard Spec
Components / BOM
  • Solenoid coil
    Generates electromagnetic field when energized to move the plunger
    Material: Copper wire with insulation
  • Plunger/armature
    Moves linearly within the solenoid to transmit force
    Material: Magnetic steel
  • Piston
    Moves within cylinder under pneumatic pressure to generate force
    Material: Aluminum alloy or stainless steel
  • Cylinder housing
    Contains and guides the piston movement
    Material: Aluminum alloy or steel
  • Return spring
    Returns actuator to default position when de-energized
    Material: Spring steel
Engineering Reasoning
0.5-10 bar (pneumatic), 12-24 VDC (solenoid), -40°C to 85°C ambient
Pneumatic: 12 bar burst pressure, Solenoid: 30 VDC dielectric breakdown, Thermal: 120°C coil insulation degradation
Design Rationale: Pneumatic: Seal extrusion failure at 12 MPa due to elastomer yield strength (3.5 MPa for NBR), Solenoid: Copper wire insulation breakdown at 30 VDC/mm, Thermal: Polyimide insulation glass transition at 120°C
Risk Mitigation (FMEA)
Trigger Hydraulic fluid contamination > ISO 4406 18/16/13
Mode: Spool valve stiction exceeding 2.5 N actuation force
Strategy: 5 μm absolute filtration with β₅≥200 at 3.5 bar differential
