Floor side member assembly as part essential in Body in white frame, to the rear portion performance impact of vehicle compared with
Greatly.For its own local function, floor side member assembly is the mostly important structural member of rear floor frame, after primarily serving support
Torsion beam action behind floor and bearing chassis.Wherein, the traditional structure of torsion beam welds one for floor side member bottom after fixing
Torsion beam installing plate improves the structural strength of floor side member afterwards, while rear torsion beam installing plate forms open U-shaped part with floor side member.Mesh
Before, the torsion beam installation region behind the chassis of floor side member assembly, easily cause rear torsion beam to drop because fatigue endurance ftractures,
Extremely serious potential safety hazard be present.
The content of the invention
The purpose of this utility model seeks to provide torsion beam mounting structure, the structural strength and rigidity after a kind of passenger car
Height, floor side member fatigue life is improved, avoid rear torsion beam and drop phenomenon.
To achieve the above object, the technical solution adopted in the utility model is：Torsion beam mounting structure after a kind of passenger car,
Including floor side member and the rear torsion beam installing plate for being fixed on the floor side member bottom, the floor side member side is sealed provided with floor side member
Plate, the floor side member shrouding are fixedly connected with side longeron extension board, and being provided with floor side member above the rear torsion beam installing plate strengthens
Plate, some sleeve pipes are connected between the floor side member reinforcing plate and the rear torsion beam installing plate；The floor side member reinforcing plate difference
It is fixedly connected with the floor side member, the side longeron extension board and the floor side member shrouding.
The utility model sets up floor side member reinforcing plate above rear torsion beam installing plate, makes itself and floor side member, floor side member envelope
Plate, side longeron extension board and rear torsion beam installing plate surround U-shaped enclosed construction together, so as to improve the local stiffness of floor side member
And intensity；And by sleeve pipe connection floor side member reinforcing plate and rear torsion beam installing plate, make the power passed over from rear torsion beam, lead to
Cross sleeve pipe to be delivered in floor side member reinforcing plate, then be delivered to floor side member side wall, reaching reduces what floor side member bottom fixing point was subject to
Power, improve the purpose of floor side member fatigue life.
Further, the floor side member reinforcing plate includes bottom plate, and the bottom edge is provided with floor side member flange, side longeron prolongs
Plate flange and floor side member shrouding flange are stretched, the floor side member flange is fixedly connected with floor side member side side wall, and the side is indulged
Beam extension board flange is fixedly connected with the side longeron extension board, and the floor side member shrouding flange is fixed with the floor side member shrouding
Connection.Floor side member flange, side longeron extension board flange and floor side member shrouding flange, increase floor side member reinforcing plate and floor side member side
The overlapping area of wall, not only improves intensity, is also beneficial to effectively transmit the power that floor side member bottom is subject to, after further avoid
Longeron fatigue cracking phenomenon.
Further, the floor side member reinforcing plate and the floor side member, the side longeron extension board, the floor side member shrouding
And the rear torsion beam installing plate surrounds U-shaped closed configuration together.
Further, the floor side member reinforcing plate is provided with reinforcement.
