Internal combustion engine throttle flap shaft bearing

摘要

The shaft is born in a divided air intake channel housing. One housing half (5) has bearing shell half sections (6) of plastic, bearing metal, etc. Each section has a counter half section formed by a flat spiral spring (7). The bearing shell part (8) of the counter section is loaded by a spring leg (10), which is deformed by the second housing half (9) during assembly. The flat spiral spring has a further spring leg (14), which is inserted into a holder aperture (15) of the bearing shell half section, and aligns the spring relative to the shaft (3).
