Abstract

The present invention provides a connection structure of an anti-torque pull rod and an auxiliary frame. The connection structure comprises the anti-torque pull rod and an auxiliary frame installation part; the anti-torque pull rod comprises large and small bushes and a pull rod support; the large and small bushes are installed inside first and second installation holes in the pull rod support; the large bush comprises a large bush inner tube, a large bush rubber body and a large bush outer tube; the large bush inner tube penetrates through the first installation hole, two large bush assembling parts stretch sideward along the axial direction of the hole, and each assembling part is provided with a large bush installation hole whose axis is perpendicular to the hole axis; the auxiliary frame installation part comprises a recess; upper plates, lower plates and support inner tubes disposed between installation plates and the lower plates are disposed at two sides of the recess; the installation plates are also provided with installation plate through holes; the large bush is installed in the recess, and fasteners penetrate through the large bush installation holes and the installation plate through holes and are connected with the support inner tubes. According to the embodiments of the present invention, excellent dynamic stiffness is maintained in all directions of the anti-torque pull rod and the auxiliary frame installation part, and automobile noise, vibration, harshness (NVH) performance can be raised.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a connection structure between a torsion-resistant tie rod and a sub-frame and an automobile. Background technique [0002] Automotive powertrain mounts generally include all mounts, torsional tie rods, damping elements and associated brackets. The anti-torsion tie rod is arranged under the powertrain, such as figure 1 As shown, the existing anti-torsion pull rod includes a small bush 1', a pull rod bracket 2' and a large bush 3', and both the large bush 3' and the small bush 1' include an inner tube 11', a rubber body 12' and an outer tube 13', and the above three are vulcanized and fixed together (such as figure 2 shown). The inner pipe of the small bush 1' is connected with the gearbox or the engine, and the inner pipe of the large bush 3' is connected with the subframe. The torsion tie rod reduces the transmission of the vibration of the powertrain to the subframe th...
