Abstract
The utility model discloses a modified fixing structure of a dynamic vibration absorber of a driving shaft, and aims to overcome the problems in the prior art. Due to the adoption of the modified fixing structure, the dynamic imbalance caused by the addition of the clamp band during the rotation of the driving shaft is reduced, and the reliability and the durability of the driving shaft assembly are improved; the overall vehicle weight is reduced; and the cost is lowered. The technical scheme is as follows: the dynamic vibration absorber is directly attached to the driving shaft through an adhesive layer.
Description
Technical field
The utility model belongs to automobile driving axle assembly technical field, and in particular, the utility model is a kind of fixed sturcture of axle drive shaft dynamic vibration absorber.
Background technology
With developing of automobile industry, people are more and more higher to the requirement of automobile various aspects of performance.For regulating the single order mode of flexural vibration frequency of axle drive shaft, dynamic vibration absorber generally is installed on axle drive shaft, at present, known axle drive shaft dynamic vibration absorber fixedly be to adopt clip fixing, as shown in Figure 1, after dynamic vibration absorber 2 is assembled on the axle drive shaft 1, be fixed on the axle drive shaft by clip 3, though clip can reach fixedly requirement, clip can additive incrementation unbalancing value in the axle drive shaft rotary course, all can bring negative effect to reliability, the durability of drive shaft assembly.
The utility model content
The utility model is for solving the fixed sturcture that a kind of improved axle drive shaft dynamic vibration absorber is provided because of the problems such as unbalancing value in the clip meeting additive incrementation axle drive shaft rotary course in the existing fixed sturcture.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of fixed sturcture of axle drive shaft dynamic vibration absorber, comprise axle drive shaft, dynamic vibration absorber, and at least one fixed end of dynamic vibration absorber is fixed on the axle drive shaft by bonding coat.During assembling, dynamic vibration absorber its faying face place by a bonding coat attached to axle drive shaft on, replace existing clip fixed sturcture, can reach the fixing fixed effect that is played of clip fully; Bonding coat weight ratio clip is light, and along the drive shaft surface rectangular distribution, does not have the gravity eccentricity issues, so can reduce the unbalancing value in the axle drive shaft rotary course that causes because of the increase clip, improve reliability, the durability of drive shaft assembly, and can alleviate complete vehicle weight, cost-cutting.Described bonding coat forms by vulcanization process.Described vulcanization process is conventionally known to one of skill in the art, comprises surface treatment, applies adhesive, heat treatment etc.
As preferably, two fixed ends of described dynamic vibration absorber all are fixed on the axle drive shaft by bonding coat.Dynamic vibration absorber can be attached directly on the axle drive shaft by bonding coat by an end, also can all be attached directly on the axle drive shaft by bonding coat by two ends, according to the installation requirement decision of dynamic vibration absorber.
Description of drawings
Fig. 1 is the outside drawing of the fixed sturcture of existing axle drive shaft dynamic vibration absorber;
Fig. 2 is an outside drawing of the present utility model;
Fig. 3 is the axial, cross-sectional view at dynamic vibration absorber of the present utility model position;
Fig. 4 is the partial enlarged drawing of a-quadrant among Fig. 3.
Description of reference numerals: axle drive shaft 1, dynamic vibration absorber 2, clip 3, bonding coat 4.
The specific embodiment
Embodiment 1:
Fig. 2 is an outside drawing of the present utility model, when assembling, faying face to axle drive shaft 1 and dynamic vibration absorber 2 two ends carries out surface treatment earlier, apply adhesive, finalize the design then and by heat treatment, form bonding coat 4 at the faying face place at axle drive shaft 1 and dynamic vibration absorber 2 two ends like this, dynamic vibration absorber 2 attached on the axle drive shaft 1, can reach fixedly requirement by bonding coat 4 fully.Because of having reduced clip, when the axle drive shaft high speed revolution, the axle drive shaft unbalancing value can reduce, and has improved reliability, the durability of drive shaft assembly; And can alleviate complete vehicle weight.
Claims (2)
1. the fixed sturcture of an axle drive shaft dynamic vibration absorber comprises axle drive shaft, dynamic vibration absorber, it is characterized in that, at least one fixed end of dynamic vibration absorber is fixed on the axle drive shaft by bonding coat.
2. the fixed sturcture of axle drive shaft dynamic vibration absorber according to claim 1 is characterized in that, two fixed ends of described dynamic vibration absorber all are fixed on the axle drive shaft by bonding coat.
