Triangle pawl is simple in construction and firm, can both realize that effectively fixation connects on the Aft cross member of automobile for itself
Connect, the firm connection to drag link can also be realized by drag link bearing pin mounting hole and metal lining；Meanwhile metal lining set
Enter inside drag link bearing pin mounting hole and welded, greatly strengthen the bonding strength of part herein.
Further, the metal lining be upper end higher than drag link mounting surface and laterally protrusion it is stepped, it is described
Stair-stepping bending part is close to the upper face of the drag link mounting surface.Make metal lining and horizontal stroke using stair-stepping bending part
Clamping relation is formd between pull bar bearing pin mounting hole, the close connection of drag link bearing pin and metal lining is ensure that, is not easy to take off
Fall, and part Cracking Failure herein after welding can be avoided.
Further, metal lining and the drag link bearing pin mounting hole is interference fits, to meet the needs of welding, and
Ensure the fastness of connection.
Further, the endoporus of the metal lining is bellmouth, its taper and the drag link ball pin bearing pin coordinated with it
Taper it is consistent, to ensure the close connection of drag link ball pin bearing pin and its bushing, avoid the drag link in vehicle motion process
Rock and produce failure and noise.
Further, first supporting plate, the second supporting plate, the bottom of the 3rd supporting plate are provided with flange, institute
The first supporting plate and the flange of the 3rd supporting plate is stated to weld with the same side of outside Aft cross member, second supporting plate
Weld the upper surface of flange and outside Aft cross member.Being brought into close contact and welding to realize this by flange and Aft cross member
The connection of the mounting structure and Aft cross member of drag link afterwards, it is simple in construction, it is easily achieved in technique, and fastness is strong.
Further, first supporting plate, the second supporting plate, the 3rd supporting plate are in respectively between drag link mounting surface
90 degree of angles to 180 degree, realize the structure of triangle pawl, and form the first supporting plate, the second supporting plate, the 3rd supporting plate
To the powerful support of drag link mounting surface, so as to form the mounting structure of firm and stable rear drag link.
Further, wire harness hole is provided with first supporting plate, it is convenient to limit surrounding wire harness.
The mounting structure of drag link passes through the drag link bearing pin mounting hole on drag link mounting surface after of the present utility model
One metal lining of interior welding, and the connection to drag link, simple in construction, technique are realized with the powerful support of three supporting plates
On be easily achieved, be connected firmly, disclosure satisfy that drag link installation strength and fatigue endurance intensity, and then ensure that the safety of automobile
Performance.
