Multiple Choice

The two pieces of collapsible steering shafts are held together by what material?

The joint between the two pieces of a collapsible steering shaft is bonded with injected plastic. This molded polymer fills the space between the tubes to create a single, smooth, torque-transmitting connection that’s lightweight and compact. It holds the sections firmly under normal steering loads while still allowing the joint to behave as intended in a crash, providing the controlled collapse or energy absorption the system is designed for. Metal fasteners would create hard points and could interfere with the designed collapse. Adhesive tape wouldn’t withstand the torque, vibration, and temperature changes in a vehicle. A rubber grommet wouldn’t reliably transmit steering torque. Injected plastic gives a durable, precise fit that meets the needs of a steering shaft assembly.
