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.

Key Features:

• Rack bore
• Retaining groove
• Thruster 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.

Key Features:

Aluminium

• Brake caliper connection
• Oil bores
• Brake pad surface
• Piston bore
• Seal and protection cap groove

Cast iron

• Flange surface (contact surface)
• U-face
• Main bore
• Seal and protection cap groove

Combined brake housing

Combined brake housing

The combination of ABS/ESP housing and master brake cylinder enables brake actuation and control in the smallest of spaces. This unit is an indispensable element for Level 5 autonomous driving and brake-by-wire systems. It reduces the braking distance compared to older systems and enables greater recuperation in electric vehicles. The integration of these functions in one component significantly increases efficiency and safety in modern vehicle construction.

Key Features:

• General milling
• Valve and connection bore
• Main bore
• Seal and oil groove
