Main bearing connecting assembly for automobile field, has screw connecting rail and bearing presenting respective hole and pin, where hole and pin are dimensioned such that connection between rail and bearing causes deformation of rail

摘要

#CMT# #/CMT# The assembly has a screw (8) for connecting a rectangular shaped steel side rail (3) and a truncated cone shaped main bearing (7) with respect to each other, where the side rail presents a circular hole (11) and the main bearing presents a emboss pin (12). The hole and the pin are dimensioned such that the connection between the side rail and the main bearing by the screw causes a local elastic deformation of the side rail at the level of the hole. The side rail has reinforcements (13a, 13b) for delimiting deformation zone around the hole. #CMT#USE : #/CMT# Used in automobile field for connecting a main bearing of a rear end of a vehicle with a chassis of the vehicle. #CMT#ADVANTAGE : #/CMT# The configuration of the hole and the pin improves shearing strength in the main bearing connecting assembly, and improves the positioning of the main bearing with respect to the chassis in a cost effective manner. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a detailed sectional view of a main bearing of a rear end and a side rail of a chassis of a vehicle once assembled. 3 : Rectangular shaped steel side rail 7 : Truncated cone shaped main bearing 8 : Screw 11 : Circular hole 12 : Emboss pin 13a, 13b : Reinforcements.
