Friction disc for Volvo A40D

The friction disc 11038721 functions within the transmission and braking assemblies of heavy machinery. It facilitates the transfer of rotational energy or the dissipation of kinetic energy through controlled surface contact. In transmission systems, these discs work in conjunction with separator plates to engage or disengage gear sets, enabling speed changes. Within braking systems, they generate the necessary resistance against mating surfaces to decelerate or stop the machine.

This component is compatible with the Volvo A40D articulated hauler. It is engineered for integration into the transmission or the wet disc brake assemblies of this specific model. These systems typically operate in an oil-submerged environment to manage thermal loads and ensure consistent engagement during operation.

Friction discs are designed to provide a specific coefficient of friction against opposing steel plates. In a transmission, they allow for smooth gear shifting by managing the torque transition between drive stages. In wet brake applications, they serve to convert kinetic energy into heat, which is then dissipated by the circulating hydraulic or transmission fluid. Maintaining the correct thickness and surface integrity of these discs is necessary for the proper function of the drivetrain and braking performance of the vehicle.
