Utility model content
The technical problems to be solved in the utility model is to provide a kind of vehicle frame and automobile, can eliminate torsion-bar spring adjustment arm Assembly and the improper stress of vehicle frame junction, improve the life-span of adjustment bolt, and ensure torsion-bar spring adjustment arm assembly and car There is certain amount of spin frame junction.
To solve above-mentioned technical problem, it is as follows that embodiment of the present utility model provides technical scheme:
On the one hand, there is provided a kind of vehicle frame, it is provided with the rear adjustment arm for adjusting arm assembly for torsion-bar spring to insert on the vehicle frame The installing hole for entering, the first end of the installing hole is spherically mounted nest, and the second end of the installing hole is that nest is installed on the face of cylinder.
Further, the first end is upper end, and second end is lower end.
This utility model embodiment additionally provides a kind of automobile, including the torsion bar of above-mentioned vehicle frame and the insertion installing hole The rear adjustment arm of spring regulating arm assembly, also including being arranged in the spherically mounted nest what is be adapted with the spherically mounted nest Sphere cushion block, and the face of cylinder cushion block be adapted with face of cylinder installation nest in the face of cylinder installation nest is arranged on, it is described Arm being adjusted afterwards and is stretched out, adjustment bolt is installed on the part of the installing hole.
Further, the rear adjustment arm stretches out and two adjustment bolts is provided with the part of the installing hole.
Embodiment of the present utility model has the advantages that:
In such scheme, the installing hole of the rear adjustment arm insertion that arm assembly is adjusted for torsion-bar spring, institute on vehicle frame, are provided with The first end for stating installing hole is spherically mounted nest, and the second end of the installing hole is that nest, torsion-bar spring adjustment arm are installed in the face of cylinder Assembly is arranged on sphere cushion block in spherically mounted nest in the junction of first end with vehicle frame, i.e., torsion-bar spring adjusts arm assembly Arm and vehicle frame being adjusted afterwards and adopting sphere-contact, torsion-bar spring adjusts the junction of arm assembly and vehicle frame at the second end by face of cylinder pad Block is arranged on the face of cylinder and installs in nest, i.e. the rear adjustment arm of torsion-bar spring adjustment arm assembly adopts Cylindrical Surfaces Contact, energy with vehicle frame The improper stress of torsion-bar spring adjustment arm assembly and vehicle frame junction is enough eliminated, is improved the life-span of adjustment bolt, and ensure to turn round Bar spring regulating arm assembly has certain amount of spin with vehicle frame junction.
Description of the drawings
Fig. 1 is the structural representation that this utility model embodiment torsion-bar spring adjusts arm assembly and vehicle frame junction;
Fig. 2 is the decomposing schematic representation that this utility model embodiment torsion-bar spring adjusts arm assembly and vehicle frame junction.
Reference
