Aluminum alloy upper and lower shells
The upper and lower housings are paired enclosures made of aluminum alloy, commonly used in core components such as engines, gearboxes, and battery packs. They are lightweight (only about 1/3 the weight of steel) and have good thermal conductivity. Additionally, they can achieve precise fitting through precision machining, balancing the requirements of strength and lightweight design.
Main Functions
1. Protection and Sealing: Act like a "protective cover" to isolate dust and moisture, while preventing leakage of internal oil and electrolyte, thus protecting precision components such as gears and circuits.
2. Support and Load-bearing: Provide stable support, capable of withstanding torque, vibration, and impact forces during operation, avoiding displacement and damage to internal components.
3. Auxiliary Heat Dissipation: Leveraging the thermal conductivity of aluminum alloy, they quickly conduct heat generated by engines and motors, preventing performance issues caused by overheating of components.
4. Fitting and Assembly: Precisely fit the internal space of the vehicle, with reserved mounting holes and positioning slots facilitating connection and assembly with other accessories.
