Function, Specifications, Materials, and Key Parameters of
DZ15221770070 Lower Side View Mirror Assembly
1. Function
The DZ15221770070 lower side view mirror assembly is designed to
enhance the driver's field of vision, particularly in areas that
are typically obscured or difficult to see, such as directly below
the cab or behind obstructions when lifting heavy loads. This
mirror helps eliminate blind spots, improves safety during vehicle
operation, and assists in maneuvers like parking, reversing, and
navigating tight spaces.
2. Specifications
• Part Number: DZ15221770070
• Application: Specifically designed for use in heavy-duty
commercial vehicles, such as certain models from Shaanxi Automobile
Group (陕汽重卡), to be mounted on the vehicle door or body to provide
an expanded field of view.
• Type: Lower side view mirror assembly, which may include a mirror
housing, mirror glass, adjustment mechanism, and mounting hardware.
• Configuration: The mirror assembly is engineered to be robust and
durable, capable of withstanding the vibrations and harsh
environmental conditions encountered in commercial vehicle
operations.
3. Materials
• Mirror Housing: Typically constructed from high-quality plastic
or a composite material to ensure durability, light weight, and
resistance to corrosion and weathering.
• Mirror Glass: Often made of glass with a reflective coating, and
may include features like anti-glare treatment or heating elements
to improve visibility in various conditions.
• Adjustment Mechanism: May utilize metal components for strength
and precision, with plastic parts for lightweight and corrosion
resistance.
• Mounting Hardware: Constructed from metal to ensure a secure and
stable attachment to the vehicle.
4. Key Parameters
• Mirror Size and Shape: The dimensions and curvature of the mirror
glass are optimized to provide the widest possible field of view
without distortion.
• Field of View: Specifically engineered to cover areas that are
not visible through the main side mirrors, such as directly below
the cab or behind obstacles.
• Adjustment Range: The mirror assembly allows for manual or
power-operated adjustments in multiple directions (up/down,
left/right) to accommodate different driver preferences and seating
positions.
• Heating Function (if applicable): Includes a heating element to
defrost the mirror glass in cold weather, improving visibility.
• Vibration and Durability: Designed to withstand the vibrations
and impacts encountered in commercial vehicle operations, ensuring
long-term reliability.
• Compliance with Standards: Meets relevant safety and performance
standards for automotive mirrors, including those related to
visibility, durability, and impact resistance.
5. English Terminology
• Lower Side View Mirror Assembly: Also referred to as an
under-mirror assembly or auxiliary side mirror.
• Mirror Housing: The outer casing that protects the mirror glass
and adjustment mechanism.
• Mirror Glass: The reflective surface that provides the view to
the driver.
• Adjustment Mechanism: The system that allows the mirror to be
moved to different positions.
• Heating Element: A component that warms the mirror glass to
prevent fogging or frosting.
• Field of View: The area that is visible through the mirror.
• Blind Spot: An area around the vehicle that is not visible to the
driver through the mirrors or direct line of sight.
