Fig. 2 is balancing weight assembling condition sectional view.
Embodiment
Embodiment, as shown in Figure 1 and Figure 2, a kind of automobile gear shifting inhaul cable balancing weight, comprise balancing weight body 1, described balancing weight body 1 one end is the fixed end 3 coordinated with drag-line pillar 2, fixed end 3 center is provided with the mounting hole 4 suitable with drag-line pillar 2, and the inwall of described mounting hole 4 is provided with screw thread, and described fixed end 3 is fixed on drag-line pillar 2 by six side's rivetings.Described screw thread comprises one group of left-handed thread 6 and one group of right-handed thread 7.Described left-handed thread 6 and right-handed thread 7 are V thread screw, and often organize screw thread at least containing 3 teeth.
Machined two sections of screw threads from both direction respectively at the fixed end 3 of balancing weight body 1, one section of screw thread is left-handed thread 6, and one section of screw thread is right-handed thread 7.Because drag-line pillar 2 epidermis one adopts the materials such as PE, PP, therefore at balancing weight body 1 after six side's rivetings, two sections of screw threads can be pressed among drag-line pillar 2 epidermis.When pulling balancing weight along drag-line pillar axial direction, due to screw thread press-in drag-line pillar epidermis, therefore creating axial inhibition, can ensureing that balancing weight has the pulling-out force met the demands when using less riveting power.
If only arrange one section of screw thread, no matter be left-handed thread or right-handed thread, although the axial pulling-out force of balancing weight can be ensured, but when if balancing weight bears the moment of rotation along hand of spiral, to be easy to rotate, if but bear rightabout moment of rotation, cannot will rotate due to the locking effect of screw thread.Based on above reason, preferably, the utility model is provided with the contrary screw thread (being respectively left-handed thread and right-handed thread) in two sections of directions in balancing weight riveting section, when balancing weight is subject to moment of rotation effect, because two sections of screw threads create the restriction preventing from rotating respectively at different direction, balancing weight namely on clockwise and counterclockwise simultaneously by locking, cannot rotate.
