Abstract
The utility model discloses a damper for an automobile transmission shaft. The damper comprises a damping body and an inner ring in the damping body, wherein a cavity for filling rubber is formed on the inner ring. Rubber and the inner ring form a firm whole body, so that the separation of the inner ring from a rubber layer caused by failure of a bonding agent or unreliable adhesion between the inner ring and the rubber layer is avoided, and the damper can be used for effectively reducing abnormal vibration of the automobile transmission shaft. The damper has the advantages of simple and compact structure, convenience for integrated and standard design and manufacturing and contribution to reducing the installation space. During manufacturing, a bonding agent is not required to be brushed in a sulfurizing process, and sand blasting is not required, so that manufacturing procedures are saved, and the production efficiency is increased; and meanwhile, the bonding agent is not required to be used, so that damage to the health of operating personnel is avoided, and environmental pollution is avoided.
Description
Technical field
The utility model relates to a kind of damping technology of truck drive shaft.
Background technique
Along with science and technology and the development of manufacturing process and the raising of living standard; The comfortableness problem paid more and more attention that automobile is taken; Resolving NVH (noise and vibration abnormal sound) problem is to improve the important content of vehicle ride comfort; The abnormal vibrations of regulation and control truck drive shaft is to solve one of vehicle NVH key of problem link among this, and mounting dampers is exactly the main means of regulation and control transmission shaft abnormal vibrations.
Vibration damper is a quality spring-damp system, and its effect is the abnormal vibrations that regulation and control transmission shaft single order mode of flexural vibration causes, but can not influence the transmission shaft balancing, characteristic such as reverses.Parameters such as appropriate quality of regulating vibration damper, rigidity, damping can be blocked the path of propagation of abnormal vibrations, obtain excellent noise reduction vibration-isolating effect.
At present, the structure (as shown in Figure 1) of existing vibration damper is made up of rubber damping body 1, interior ring 3, adopts vulcanization that rubber damping body 1 and interior ring 3 are bonded together.Ring 3 needs to brush tackiness agent in before the sulfuration, if adhesive failure or interior ring and rubber are bonding unreliable, ring separates with rubber layer in can causing, and then influences effectiveness in vibration suppression.
Summary of the invention
The goal of the invention of the utility model is to overcome the above-mentioned deficiency of existing technology and a kind of used for vehicle transmission shaft vibration damper is provided, and effectively stops the hidden danger of separating of damping medium and interior ring, guarantees the favorable damping effect.
The technological scheme of the utility model is: comprise the interior ring in damping body, the damping body; Ring is provided with the cavity that is used for filled rubber in said.
Said cavity is the cavity of radial arrangement.
Ring is provided with axial cavity in said.
Said axial cavity is connected with radial cavities.
Said damping body is a rubber.
Said damping body outside is provided with the positioning step that encircles in the location when being used to vulcanize.
The utility model makes rubber and interior ring form a firm integral body, avoids guaranteeing that because of ring in adhesive failure or interior ring and bonding unreliable the causing of rubber layer separates with rubber layer vibration damper can effectively reduce the abnormal vibrations of truck drive shaft.The utility model compactness simple for structure is convenient to integrated, standardized designs manufacturing, helps reducing installing space.When the utility model is made, in sulfidation, need not brush tackiness agent, not need sandblast, save manufacturing process, improve manufacturing efficiency; Because must not use tackiness agent, avoid operative employee's health hazards simultaneously, also avoided the pollution of environment.

Embodiment
Among Fig. 2, Fig. 3, the utility model embodiment 1 comprises the interior ring 3 in damping body 1, the damping body 1.Interior ring 3 is provided with the radial cavities 2 that is used for filled rubber.Radial cavities 2 in the utility model on the ring 3 after can guaranteeing to vulcanize, also has been full of rubber in the radial cavities 2 of interior ring 3, thereby has made rubber and interior loops synthesize a firm integral body.4 is positioning step.
Among Fig. 4, damping body 1 outside is provided with positioning step 4.
Among Fig. 5,3 is interior ring, and 2 is radial cavities.
Among Fig. 6, the utility model embodiment 2 comprises the interior ring 3 in damping body 1, the damping body 1.Interior ring 3 is provided with radial cavities 2, the axial cavity 5 that is used for filled rubber.Axial cavity 5 can be communicated with radial cavities 2, also can not be communicated with.
Among Fig. 7, Fig. 8,2 is radial cavities, and 3 is interior ring, and 5 is axial cavity.
Manufacturing process's process of existing drive shaft absorber is such: interior ring machining moulding → interior ring surface is handled (like sandblast etc.) → interior ring surface cleaning → interior ring surface and is brushed tackiness agent → sulfidization molding.Manufacturing process's process of the utility model is such: interior ring machining moulding → interior ring surface cleaning → sulfidization molding.Can find out that from the comparison of above-mentioned manufacturing process process manufacturing process's process of the utility model has reduced two procedures compared to prior art, has accelerated manufacturing rhythm.Tackiness agent can influence health usually, and can produce certain environmental pollution.After adopting the utility model, after having cancelled tackiness agent and brushing operation, stopped this negative factor fully.
