Przegubach

Przegubach is a Polish term that translates to "joints" or "articulations" in English. In mechanical engineering, it most commonly refers to universal joints, also known as U-joints or Cardan joints. These are mechanical couplings used to connect rotating shafts that are not in alignment. They are crucial for transmitting rotational power between components that may experience relative motion or misalignment, such as in vehicle drivetrains. A typical universal joint consists of a pair of hinges arranged at 90-degree angles to each other, connected by a cross shaft. This design allows for a change in the angle of rotation between the input and output shafts.

The primary function of a przegubach in automotive applications is to allow the driveshaft to transmit power from the transmission or transfer case to the differential, even as the suspension moves and the chassis flexes. Without them, the constant angular changes would cause binding and stress in the drivetrain. Other applications for universal joints include steering columns, industrial machinery, and robotics, wherever flexible connections between rotating shafts are required.

While the term przegubach can broadly refer to any joint, its context in technical discussions heavily implies universal joints. The design and material selection for przegubach are critical for durability and performance, as they are subjected to significant torque and stress.
