Abstract
The utility model discloses a screw shock-absorbing device for an automobile semi-axle. The screw shock-absorbing device comprises a bolt hole in a semi-axle flange disc, wherein an elastic ring is embedded in the bolt hole, the outer ring of the elastic ring is matched with the inner hole of the bolt hole, and the inner ring of the elastic ring is matched with the diameter of a bolt; the elastic ring is provided with a step, and the step surface is fitted with the outer end surface of the bolt hole; the elastic ring is a silica gel ring. According to the screw shock-absorbing device disclosed by the utility model, elastic connection between the bolt and the flange disc is realized by embedding the elastic ring in the bolt hole, thus impact brought by shock can be effectively alleviated, the loosening of the bolt can be prevented, the connection soundness between the flange disc and an axle body can be enhanced, and the maintenance and replacement frequency of the semi-axle can be reduced.
Description
Technical field
The utility model relates to a kind of automobile axle shaft, is specifically related to a kind of automobile axle shaft screw shock absorption device.
background technology
In vehicle traveling process, particularly, under the bad situation of road conditions, because vibrations are larger, the bolt on automobile axle shaft is easy to become flexible.In addition, if rear-axle differential gap is large, can cause starting to walk unstable, the stressed dash of semiaxis is large, also easily makes semiaxis bolt looseness or fracture.For a long time like this, while not only needing routine repair cost, require great effort, affect automobile normal running, more can produce certain potential safety hazard, the person and property safety are impacted.
Summary of the invention
For above-mentioned defect, the utility model provides a kind of axle shaft screw shock absorption device with certain buffer action, slows down axle shaft screw and becomes flexible or phenomenon of rupture.
The utility model is achieved through the following technical solutions:
An automobile axle shaft screw shock absorption device, comprises the bolt hole on semiaxis flange, and bolt hole is embedded with elastic ring, and the outer ring of elastic ring coordinates with bolt hole endoporus, and inner ring coordinates with the diameter of bolt.
The further improved technical scheme of the utility model is: described elastic ring is provided with step, terrace and the laminating of bolt hole outer face.
Described elastic ring is silica gel ring.
The utility model, by being embedded in elastic ring at bolt hole, being realized bolt and is connected with the elasticity between flange, can effectively slow down the impact that vibrations bring, and prevents bolt looseness, and then the frequency that reduces semiaxis maintenance or change.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of automobile axle shaft screw shock absorption device, comprises semiaxis flange 1, along flange 1 circumferencial direction, is evenly distributed with bolt hole 2.Elastic ring 3 is embedded in bolt hole 2, and its outer ring coordinates with the endoporus of bolt hole 2, and inner ring coordinates with the diameter of bolt.Elastic ring 3 is also provided with step 4, terrace and the laminating of bolt hole outer face.When operation, can first elastic ring 3 be embedded in bolt hole 2, then bolt be inserted in the inner ring of elastic ring 3, then fastening nut.By the elasticity of elastic ring 3, effectively slow down the impact that brings of vibrations, prevent bolt looseness, strengthen the impregnability that is connected of flange 1 and pontic, the while also reduces maintenance and the replacement frequency of semiaxis.
Described elastic ring 3 is silica gel ring, and elastic performance is superior.
Claims (3)
1. an automobile axle shaft screw shock absorption device, comprise the bolt hole (2) on semiaxis flange (1), it is characterized in that: described bolt hole (2) is embedded with elastic ring (3), elastic ring (3) outer ring coordinates with bolt hole (2) endoporus, and inner ring coordinates with the diameter of bolt.
2. automobile axle shaft screw shock absorption device according to claim 1, is characterized in that: described elastic ring (3) is provided with step (4), terrace and the laminating of bolt hole outer face.
3. automobile axle shaft screw shock absorption device according to claim 1 and 2, is characterized in that: described elastic ring (3) is silica gel ring.
