Automobile electric power steering system's noise reduction mechanism and support that contracts of bursting

The utility model provides an automobile electric power steering system's noise reduction mechanism, including the backup pad, be equipped with bellied bending plate in this backup pad, this bending plate and backup pad integrated into one piece, bending plate have a bending plate and the 2nd bending plate, and a bending plate one end links to each other with the backup pad is fixed, the other endand the 2nd bending plate fixed connection, the 2nd bending plate is parallel with the backup pad, is equipped with the mounting hole on the 2nd bending plate, installs the block rubber in the mounting hole. Through set up bellied bending plate in the backup pad to set up the block rubber on bending plate, make noise reduction mechanism, and with the welding of the backup pad of this noise reduction mechanism at a steering system support body lower extreme, make the support that contracts of bursting, thus when making the tubular column follow the clamping system and adjust downwards, beforestationary cam stabilizer
