Where are automotive components (general structural parts) mainly used
The general structural components in automotive parts are the basic components that make up the vehicle skeleton and support system. Their functions include carrying, connecting, protecting, and maintaining the body shape, and are widely used in various core systems of automobiles. The following will explain the application scenarios, typical components, and functional characteristics:
The general structural components in automotive parts are the basic components that make up the vehicle skeleton and support system. Their functions include carrying, connecting, protecting, and maintaining the body shape, and are widely used in various core systems of automobiles. The following will explain the application scenarios, typical components, and functional characteristics:
1、 Body structure system: shaping the body frame and safety protection
1. Body frame components
Typical components: frame longitudinal beams, crossbeams, A/B/C pillars, roof frame, threshold beams, etc.
Application scenario: Forming the main body framework of the vehicle, bearing the impact force, torsional force, and passenger weight during vehicle operation.
Functional features: Made of high-strength steel or aluminum alloy material, connected by welding or bolts to ensure the rigidity of the vehicle body (such as reducing deformation of the passenger compartment by absorbing energy through structural components during collisions).
2. Structural components of car doors and windows
Typical components: door inner panel, door collision beam, window guide rail, hinge bracket, etc.
Application scenarios: Support door opening and closing actions, fix glass lifting systems, and enhance door impact resistance.
Functional features: Anti collision beams (such as U-shaped or W-shaped steel beams) can disperse the impact force during side collisions and protect occupants inside the vehicle.
2、 Chassis system: connecting power and carrying driving load
1. Suspension system structural components
Typical components: lower swing arm, shock absorber mount, subframe, lateral stabilizer bar, etc.
Application scenario: Connecting wheels and body, buffering road bumps, and maintaining tire grip.
Functional features: The subframe (such as Yuanbaoliang) can reduce the impact of engine vibration on the vehicle body and improve handling stability.
2. Transmission and braking structural components
Typical components: drive shaft bracket, brake disc mounting bracket, brake caliper bracket, etc.
Application scenario: Fixed transmission components (such as transmission shafts), supporting the operation of the braking system (such as caliper brackets fixing brake calipers to ensure braking force transmission).
3、 Power system: supports the operation of the engine and gearbox
1. Engine support structural components
Typical components: engine mount (foot glue), cylinder block, oil pan, etc.
Application scenario: Fixing the engine to the frame, absorbing operational vibrations, and protecting internal engine components.
Functional features: The machine foot rubber buffers engine vibration through rubber or hydraulic materials to avoid resonance affecting the driving experience.
2. Transmission case and bracket
Typical components: gearbox housing, shift mechanism bracket, etc.
Application scenario: accommodates gearbox gear sets, supports gear shifting operations, and transmits power to drive wheels.
4、 Walking system: ensuring the connection between the wheels and the body of the vehicle
1. Wheel hub and wheel rim
Typical components: aluminum alloy wheels, steel wheels, etc.
Application scenario: Installing tires, supporting vehicle weight, transmitting driving and braking forces.
Functional features: Lightweight wheels (such as aluminum alloy) can reduce unsprung mass and improve handling response.
2. Axle and half axle sleeve
Typical components: front axle housing, rear axle housing, half shaft sleeve, etc.
Application scenario: Connecting left and right wheels, supporting vehicle weight, transmitting power (drive axle) or steering force (steering axle).
5、 Interior and Accessories: Installation of Supporting Function Components
1. Dashboard skeleton
Typical components: metal or plastic frame, fixed dashboard, air conditioning vents, airbags, etc.
Application scenario: Ensure stable installation of interior components and protect the airbag deployment path in case of collision.
2. Seat frame
Typical components: seat frame, adjustment mechanism bracket, etc.
Application scenario: Support passenger weight, achieve seat front back and backrest angle adjustment, and some models include anti-collision steel beams to enhance safety.
