In a specific embodiment, the present invention provides a kind of front suspension swinging arm mechanism of automobile, the front suspension swinging arm mechanism packet
Include stringer 12 and connection reinforcement box 13 under front overhang lower swing arm 11, front deck.
As depicted in figs. 1 and 2, stringer 12 extends along the length of wagon direction of automobile under front deck, and connection reinforcement box 13 is fixed
Under front deck on stringer 12, also, the tie point of connection reinforcement box 13 is towards the outside of body of a motor car, to be used for and the front overhang bottom
Arm 11 connects.Wherein, connection reinforcement box 13 can be fixed by welding under front deck on stringer 12, be pacified with enhancing stringer 12 under front deck
The intensity at front overhang lower swing arm 11 is filled, provides reliable, firm installation point for front overhang lower swing arm 11.
As shown in figure 3, connection reinforcement box 13 has two installation bases 131 of the convex installment surface in connection reinforcement box 13,
Two installation bases 131 are equipped with the connecting hole of installation front overhang lower swing arm 11, and installment surface refers to the one of installing front overhang lower swing arm 11
Side.Each installation base 131 respectively corresponds the mounting base of front overhang lower swing arm 11, also, steel-wire screw-socket 23 is equipped in connecting hole,
Bolt 24 passes through the mounting base of front overhang lower swing arm 11 and screws in connecting hole, with the fixed front overhang bottom of 23 threaded of steel-wire screw-socket
Arm 11 and connection reinforcement box 13, in combination with shown in Fig. 1 and Fig. 2.
Wherein, two connecting holes are opened up on each installation base 131, front overhang lower swing arm 11 can be firmly fixed.Certainly,
The quantity of connecting hole can be set according to installation requirements, therefore, the particular number of connecting hole not to this application claims
Technical solution is construed as limiting.
The surface of mounting base is fitted in the surface of installation base 131, the surface shape of installation base 131 and mounting base
Shape matches, to come into full contact with mounting base, to provide sufficient installation support.
Connection reinforcement box 13 is also provided with lightening hole 132, further decreases the weight of the connection reinforcement box 13.The lightening hole
132 avoid the setting position of installation base 131.
Stringer 12 offers the installation gap of the fixed position of limit connection reinforcement box 13 under front deck, in conjunction with Fig. 2 and ground Fig. 4 institute
Show, the installed position of the corresponding front overhang lower swing arm 11 of stringer 12 sets that there are two installation gap, two connection reinforcement boxes 13 under front deck
It limits at installation gap respectively, so as to which securely, steadily connection reinforcement box 13 is fixed under front deck on stringer 12.Specifically
Ground, connection reinforcement box 13 are welded under front deck at the installation gap of stringer 12.
Also, after opening up installation gap on stringer 12 under front deck, connection reinforcement box 13 is embedded under front deck in stringer 12,
