Abstract
The invention discloses an automotive transmission shaft installing and fixing structure which comprises a transmission shaft fixing cross beam fixed to the lower surface of a front floor. The transmission shaft fixing cross beam is composed of a cross beam body and a transmission shaft fixing seat welded and fixed to the outer surface of the cross beam body. A reinforcing cross beam symmetrical to the transmission shaft fixing cross beam in position is welded and fixed to the upper surface of the front floor. The automotive transmission shaft installing and fixing structure has better rigidity and intensity and can meet the requirements for bearing capacity and fixing reliability.
Description
Technical field
The present invention relates to field of car body structure, be specially a kind of novel mount fixing structure of propeller-shaft.
Background technology
Current AWD or in good time 4 wheel driven have become must configuring of large-scale SUV, the tween drive spindle of four-wheel drive cars is divided into syllogic and two sectional type, wherein to compare the cost performance of syllogic more excellent for two sectional type tween drive spindle, but the installation of two sectional type tween drive spindle to fix difficulty larger than three-piece propeller shaft.
As patent CN201020539712.8 and CN201310574243.1 individually discloses the supporting construction for transmission shaft, but this support fixed structure is mainly used in the micro-car of front-engine rear-drive type, 4 wheel driven SUV vehicle can not be met fixing requirements at the higher level are installed for two sectional type tween drive spindle.
Summary of the invention
The object of the present invention is to provide a kind of propeller-shaft mount fixing structure, there is good stiffness, meet the requirement of load and fixing reliability.
Propeller-shaft mount fixing structure of the present invention, comprise the transmission shaft fixed cross beam being fixed on front floor lower surface, described transmission shaft fixed cross beam is made up of cross-beam body and the transmission shaft permanent seat being weldingly fixed on cross-beam body outside face, described cross-beam body is U-shaped girder construction, it is left, right two ends are left with floor respectively, the right beam is welded and fixed, before cross-beam body, trailing flank is fixed by flange and front floor welded, described transmission shaft permanent seat cross section is class W type, there is in the middle part of it arc arch, a left side for this transmission shaft permanent seat, the bottom surface of right two ends and summit, arc arch and described cross-beam body is welded and fixed, before transmission shaft permanent seat, before trailing flank and cross-beam body, trailing flank is welded and fixed, the left and right sides, the bottom place of described transmission shaft permanent seat arc arch has mounting plane, described mounting plane offers transmission shaft mounting hole.Be welded with the deep beam with described transmission shaft fixed cross beam positional symmetry at described front floor upper surface, the left and right two ends of described deep beam also with floor left and right side bar welding fix.
Preferably, described transmission shaft fixed cross beam is installed between front cross rail and front-row seats installation after cross member at front-row seats.
Transmission shaft mount fixing structure of the present invention can meet functional stabilization and the reliability requirement of transmission shaft in driving conditions, there is good stiffness and noise robustness, structure is simple, be beneficial to processing and implementation, through cae analysis and verification experimental verification, effectively can meet 4 wheel driven SUV two sectional type tween drive spindle and fix requirement.
