 Automobile parts

 Automobile parts usually refer to all parts and components except the frame of the car. The frame can also be considered as a component, but it is not the same concept as the parts.

 Among them, parts refer to single components that cannot be separated; components refer to a combination of parts that realize a certain action (or: function). A component can be a single part or a combination of multiple parts. In this combination, there is a main part that realizes the given action (or: function), and the other parts only play auxiliary roles such as connection, fastening, and guidance.

1. Parts

Parts refer to single finished products or parts that are made directly without assembly processes, or parts that are connected together by more than two parts and have specified functions, which usually cannot be further decomposed. For example, tires, wheels, pistons, etc. are all parts.

2. Units

Units are combinations of parts that have a certain specific function. They can usually work independently in different environments and have high functionality and independence. For example, the electronic control unit (ECU) and fuel pump module of the car.

3. Subassembly

Subassembly refers to a part that is assembled by two or more parts through an assembly process and has a subordinate assembly relationship with the subassembly. For example, the clutch subassembly, seat adjustment subassembly, etc.

4. Subassembly

Subassembly refers to a component that is assembled by multiple parts and subassemblies through an assembly process and has a subordinate assembly relationship with the assembly. For example, the transmission subassembly, steering system subassembly, etc.
