Embodiment Construction
[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings to facilitate a clearer understanding of the present invention, but they do not limit the present invention.
[0028] Such as Figure 1~6 As shown, a torsion-resistant rod structure of a powertrain includes a torsion-resistant rod frame 1. Both ends of the torsion-resistant rod frame 1 are provided with a hollow large bushing installation sleeve 11 and a small bushing installation sleeve 12, and the large bushing is installed The sleeve 11 is fixedly connected with a large sleeve 3, and the small sleeve mounting sleeve 12 is fixedly connected with a small sleeve 4. The large sleeve 3 includes a large sleeve rubber ring 32 and a large sleeve inner liner 33. The large sleeve rubber The ring 32 is located between the large bushing installation sleeve 11 and the large bushing inner liner 33 and is fixed as a whole by vulcanization. The small bushing 4 includes a small ...

The invention discloses a torsion-resistant pull rod structure of a power assembly. The torsion-resistant pull rod structure of the power assembly comprises a torsion-resistant pull rod framework, wherein the two ends of the torsion-resistant pull rod framework are respectively provided with a large bushing and a small bushing; the large bushing comprises a large bushing rubber ring and a large bushing liner; the large bushing rubber ring is provided with a forward gear rubber impact block and a reverse gear rubber impact block; the ends of the forward gear rubber impact block and the reversegear rubber impact block are tapered; the two sides of the forward gear rubber impact block are provided with forward gear impact block buffer grooves; and two sides of the reverse gear rubber impactblock are provided with reverse gear impact block buffer grooves. According to the invention, the rigidity curves of an initial section and an end section in an acceleration process of a three-gear area are smooth, and abrupt change of rigidity does not exist, so that the vibration strength is reduced, and the NVH performance of a whole vehicle is improved; and a special gasket is arranged betweenthe large bushing liner and a front auxiliary frame assembly, and a small bushing rubber ring is provided with a limiting boss and a buffer groove, so that the connection stability of the two ends ofa torsion-resistant pull rod is enhanced.
Description
Technical field [0001] The invention belongs to the technical field of powertrain suspension systems, and specifically refers to a torsion resistant pull rod structure of a powertrain. Background technique [0002] The main function of the anti-torsion mount in the automotive powertrain is to limit the torsional displacement of the powertrain and isolate the torsional vibration of the powertrain. The torsion-resistant suspension is usually composed of a torsion-resistant rod and a torsion-resistant bracket. The end of the torsion-resistant rod near the large bushing is usually connected with the front bracket by bolts. The anti-torsion rod can effectively reduce the vibration intensity transmitted from the powertrain end to the interior of the car. [0003] Chinese patent CN106314116A discloses a torsion resistant rod. The forward stop rubber limit block of the torsion resistant rod has a certain gap with the inner tube of the large bushing and the outer tube of the large bushing,...
