底盘和制动器
由于电池系统导致车辆重量增加,底盘和制动组件中铝的比例不断增加。因为铝确保了高稳定性和减轻的重量。与此同时,由于“线控转向”、“线控制动”以及自动驾驶等创新技术,这些组件不断得到进一步发展。此外,诸如一体化压铸或巨型铸造之类的新制造方法开辟了新的发展机会,例如更大的组件尺寸,使得车身的各个部分可以单件制造。
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:
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:
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:
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:
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:
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.
