Applications in Automobile
The diagram illustrates the distribution of PM parts in automobiles:
Powertrain System: Components such as valve seats, guide rings, connecting rods, bearing caps, VVT system parts, and exhaust pipe seats.
Transmission System: Including synchronizer hubs and planetary carriers.
Chassis System: Shock absorber parts, pistons, and guide assemblies.
Braking System: ABS sensor rings and brake pad inserts.
Pump Systems: Critical components within fuel pumps, oil pumps, and transmission pumps.
In recent years, the focus on energy saving and emission reduction has driven the rapid development and adoption of three key types of PM parts: Variable Valve Timing (VVT) components, variable displacement oil pumps, and brake vacuum booster pumps. Advancements in PM technologies—such as high-density sintering, the fabrication of complex composite parts, and the use of specialized alloys—are enabling the production of these components with the required strength, wear resistance, and precision, making them essential for next-generation, efficient vehicles.
