Fore sub frame attachment point structure, set by fore sub frame and front stringpiece of vehicle body rear portion, subframe permanent seat is bolted, and set by described subframe permanent seat and described front stringpiece of vehicle body rear portion, longitudinal beam reinforcing plate is connected to form an enclosed cavity; Described longitudinal beam reinforcing plate is provided with to be located in described enclosed cavity for the sleeve that described bolt passes; Described subframe permanent seat is provided with and described bolted nut seat.
Described front stringpiece of vehicle body rear portion is provided with the front side member rear portion upper reinforcing plate be connected with described subframe permanent seat bottom.
Described nut seat is welded on described subframe permanent seat.
Described sleeve weld is on described longitudinal beam reinforcing plate.
Described front side member rear portion upper reinforcing plate and the welding of described subframe permanent seat bottom.
It is coaxial that the subframe that described sleeve, nut seat and described bolt are set with installs rubber bush.
The utility model has the advantage of: first, the enclosed cavity that front stringpiece of vehicle body rear portion, longitudinal beam reinforcing plate and subframe permanent seat are connected to form improves the rigidity in X, Y, Z tri-directions, fore sub frame attachment point place; Make three bear load simultaneously, effectively reduce the intensity risk of front stringpiece of vehicle body rear portion and subframe permanent seat, high degree improves the Rigidity and strength of fore sub frame attachment point.
Secondly, sleeve only freezes with longitudinal beam reinforcing plate, and bolts and nuts seat adopts the mode of tools for bolts ' pretension to fix, and while lift structure intensity, reduces assembly difficulty.
Thirdly, subframe is directly installed on body assembly, does not need to arrange mounting structure between, reduces car load assembly quantity, decreases subframe installation procedure simultaneously, improves car load efficiency of assembling.
Finally, subframe mount structure and vehicle body reinforcing structure unite two into one, and reduce panel beating quantity and complete vehicle weight, not only reduce cost, also meet weight-saving requirement.
