Utility model content
The automotive track bar that the utility model provides, by the improvement to bar linkage structure, strengthens the anti-torsion load of propelling rod, counter-bending load and anti-buckling loading ability, improves the reliability of automotive track bar.
For achieving the above object, the technical solution adopted in the utility model is: automotive track bar, comprise connecting rod and the bulb being fixed on connecting rod two ends, it is characterized in that the quantity of described connecting rod is two, connecting rod described in two is symmetrical up and down with the horizontal central line of described bulb, the cross-sectional plane of described connecting rod is camber cross section or Irregular Boundary Surface setting and the cross-sectional plane of two connecting rods is centrosymmetric, and the distance between two connecting rods increases with the increase of described automotive track bar design strength.
Further, the shape of described connecting rod end face and the matching form of bulb outside face close, and the end face of described connecting rod can be fitted on the outside face of bulb.
Further, described connecting rod by draw exchange work skill or Sheet Metal Forming Technology shaping, the shape of described connecting rod end face by machinework or Sheet Metal Forming Technology shaping.
Further, the cross-sectional plane of described connecting rod is semi arch cross section.
Further, the two ends of described connecting rod are fixed on the outside face of bulb by welding process laminating.
The beneficial effects of the utility model are: the automobile trolley pole that this reality is novel, the quantity of the connecting rod between two bulbs is two, two connecting rods are symmetrical up and down with the horizontal central line of bulb, the cross-sectional plane of connecting rod is camber cross section or Irregular Boundary Surface setting and the cross-sectional plane of two connecting rods is centrosymmetric, cross-sectional plane is that two connecting rods of camber cross section or the irregular curve type cross section setting and cross-sectional plane is centrosymmetric are compared with the circular section connecting rod of homalographic, its anti-torsion load, counter-bending load and anti-buckling loading higher, and distance between two connecting rods can be designed according to automotive track bar design strength, when the design maximum carrying capacity of automobile increases, the design strength of automotive track bar increases, distance between two connecting rods increases thereupon, the torque load that automotive track bar can be born and flexural load increase, by the improvement to bar linkage structure, strengthen the anti-torsion load of propelling rod, counter-bending load and anti-buckling loading ability, improve the reliability of automotive track bar.
