Problems solved by technology

Usually, in the development process of a new car, such a trial production process needs to be repeated for 3 to 5 rounds, which lasts for about 3 months.
Therefore, the trial production and testing of this prior art torsion tie rod in the traditional vehicle development process not only caused a waste of resources, but also took a lot of time
At the same time, due to the long interval of trial production, after the trial production of the new torsion tie rod is completed, the evaluators need to re-evaluate the original parts in order to compare with the new parts, and a lot of time wasted

Abstract

The invention relates to an anti-torque pull rod, which comprises a support, a liner bushing outer ring, a main spring, a fixing device and an adjustable limit block, wherein the liner bushing outer ring is detachably mounted on the support, the main spring is vulcanized on the liner bushing outer ring and the limit block is mounted on the support through the fixing device; and the fixing device is a bolt matched with a nut, the main spring is a rubber main spring with variable rigidity and the limit block is replaceable and in various shapes. During the development, in use, the main spring with the variable rigidity is firstly vulcanized on the liner bushing outer ring and then the liner bushing outer ring is detachably mounted on the support; when in use, a gap between the limited block and the main spring is adjusted by regulating the nut. As the main spring is detachable and the gap is adjustable, parts for trial production are reduced; therefore, the cost is reduced, the debugging time is saved and the continuity of regulation work becomes strong.

Description

【Technical field】 [0001] The invention relates to a torsion tie rod used in the development process. 【Background technique】 [0002] In the vehicle development process, it involves the debugging and matching of the powertrain suspension system. The anti-torsion tie rod plays a role in limiting the displacement of the powertrain and isolating the transmission of powertrain vibration to the body in the vehicle. These two are mutually exclusive requirements reflected in the design of the torsion tie rod. In the design process, it is hoped that the stiffness of the main spring is high to limit the displacement of the powertrain, but it is also hoped that the stiffness of the main spring is low to better isolate the powertrain. Transmission of vibrations to the body. The distance between the main spring and the limit block can effectively increase the stiffness after contact, thereby limiting the displacement of the powertrain, but at this time it will cause the vibration of th...
