底盘和制动器

属于底盘领域的聚焦部件

回转轴承/轮架

回转轴承/轮架

后轴上的轮架和前轴上的回转轴承负责支撑车轮，为汽车底盘结构中的重要部件，对于驾驶舒适性和安全性至关重要。它们用作轮毂、制动盘、制动钳和横向控制臂的装夹点。它们的设计根据车轴方案的不同而有所不同，以满足特定的车辆要求。这些部件必须能够承受高车轮负载，因此由坚固、耐腐蚀的材料制成，例如锻压铝材或球墨铸铁。其坚固的结构确保了车辆的性能和安全性，并有助于提高整体质量。

亮点加工：

• 推力支撑、外倾支撑和拉杆支撑
• 主轴承孔的预加工
• 主轴承孔

横向控制臂

Wishbone

横向控制臂是汽车独立悬吊系统的重要组成部分，负责车轮的悬掛系统。它们吸收车轮和车身之间的侧向力。根据具体的轴方案，有多种几何解决方案。横向控制臂必须承受高车轮负载，应该是耐腐蚀且具有高强度。它们在驾驶机械中发挥核心作用，并对安全性和舒适性做出了重大贡献。

亮点加工：

• 半球体孔

Driving stool

Driving stool

The subframe is a load-bearing element of the vehicle body and serves as a pivot point for the wheel suspension. The engine and gearbox are also mounted on the front axle. Thanks to its design, the chassis frame facilitates assembly during vehicle production. It also contributes to increased driving comfort by minimizing vibration and noise while driving.

Highlights machining:

• Cross bridge
• Push strut
• Bogie bearing bore
• Camber strut

Gigacasting/Megacasting

Gigacasting/Megacasting

New production technologies such as giga- and megacasting are revolutionizing the automotive industry. Instead of several individual parts, complex structural components are now produced in a single casting. Aluminum alloys are used to produce larger, lighter and yet robust components. These processes promise weight savings, higher performance and safety in future vehicles.

Focus components from the brakes sector

Steering housing

Steering housing

The steering gear transmits the rotary movement of the steering wheel to the front axle of the vehicle via the tie rod. The steering torque is transmitted by means of a pinion and rack, which are located in the steering housing. The trend towards steer-by-wire systems enables improved driving and steering characteristics. This technology also lays the foundation for autonomous driving by enabling more direct and precise steering. Overall, the steering gear plays a central role in the steering capability and safety of the vehicle.

Highlight machining:

• Motor bore
• Rack bore
• Holding groove
• Steering pinion bore
• Thrust piece bore

Brake caliper

Brake caliper

The brake caliper is a safety-relevant component in the vehicle that is exposed to high thermal and mechanical loads. When the brake pedal is pressed, brake fluid is fed to the brake caliper piston, which presses the brake pads against the disk. Depending on the vehicle type and engine, there are different designs and the number of pistons varies.

Highlight machining:

• Brake caliper connection
• Piston bore and U-surface
• Sealing and protective cap groove

Combined brake housing

Carcaça de freio combinada

A combinação da carcaça do ABS/ESP e do cilindro principal do freio permite o acionamento e o controle do freio nos menores espaços. Esta unidade é um elemento indispensável para os sistemas de direção autônoma Level 5 e Brake-by-Wire. Ela reduz a distância de frenagem em comparação com os sistemas mais antigos e permite uma maior recuperação nos veículos elétricos. Por meio da integração destas funções em um único componente, a eficiência e a segurança aumentam significativamente na construção de veículos modernos.

Usinagens em destaque:

• Furo do cilindro principal do freio
• Conexão da porta
• Furo do cilindro principal
