Abstract
The utility model relates to an internal structure of a tensioning wheel assembly of a front-end gear train of an automobile engine. The internal structure of the tensioning wheel assembly of the front-end gear train of the automobile engine comprises a first tensioning arm and a second tensioning arm, wherein a spring is arranged between the first tensioning arm and the second tensioning arm; a cavity is formed inside the first tensioning arm; a bearing is formed inside the cavity; a core shaft is fixedly connected on the second tensioning arm; and the core shaft is matched with the bearing. According to the technical scheme, the problem that the conventional plastic component in the tensioning wheel assembly is not wear-resistant is solved, the original riveting installation way is cancelled, the installation is more convenient, the assembling efficiency of a product is improved and the service life of the product is prolonged.
Description
Technical field
The utility model relates to engine fittings, is specifically related to a kind of internal structure of motor car engine front end train stretching wheel assembly.
Background technique
Available engine stretching wheel assembly internal structure is as shown in Figure 1; Its structure comprises that accessories such as first tension arms 01, second tension arms 02, torsion spring 03, tension arms plastic bushing 04, spring plastic bushing 05 and anti-attrition plastic bushing 06 form; Torsion spring 03 is anti-attrition plastic bushing 06 and first tension arms 01 and the 02 meeting generation friction of second tension arms in reversing the process of work; The aging stretching wheel assembly early failue that causes of working of plastics; The assembly string quantity of motion increases, and belt deviation causes working life short.
Summary of the invention
To the deficiency that existing technology exists, it is a kind of simple in structure that the purpose of the utility model is to provide, the internal structure of the motor car engine front end train stretching wheel assembly of efficiency of assembling height and long service life.
For realizing above-mentioned purpose; The utility model provides following technological scheme: a kind of internal structure of motor car engine front end train stretching wheel assembly, comprise first tension arms and second tension arms, and be provided with spring between said first tension arms and second tension arms; Be provided with cavity in said first tension arms; Be provided with bearing in the said cavity, be fixedly connected with mandrel on said second tension arms, said mandrel and bearing are suitable.
Through adopting technique scheme, solved existing working of plastics not wear-resisting problem in stretching wheel assembly, cancelled original riveted joint mounting type, improved the working life and the efficiency of assembling of stretching wheel assembly.
The utility model further is set to: described bearing is the biserial angular contact bearing, and the outer end that said biserial angular contact bearing cooperates with mandrel is provided with nut, and second tension arms is fixedly clamped through the nut and first tension arms.Through this setting, use the biserial angular contact bearing to solve existing stretching wheel assembly oscillating quantity problem bigger than normal, simple in structure, reliable operation has further prolonged working life.
The utility model also further is set to: said mandrel is fixedly connected with second tension arms formation through burning casting.Through this setting, the mandrel and second tension arms are fixing reliable.
The utility model also further is set to: be provided with metallic shim between said second tension arms and the biserial angular contact bearing.Through this setting, can prevent that the biserial angular contact bearing from destroying the end face of second tension arms, thereby improve the quality, and be convenient to assembling.
The utility model has the advantages that the aluminum casting material that reduces tension arms, solved existing working of plastics not wear-resisting problem in stretching wheel assembly, cancelled original riveted joint mounting type, easier for installation, the efficiency of assembling and the working life of having improved product.
Below in conjunction with Figure of description and embodiment the utility model is done further introduction.
Description of drawings
Fig. 1 is the prior art constructions schematic representation;
Fig. 2 is the utility model embodiment's a structural representation.
Embodiment
Referring to accompanying drawing 2; The internal structure of the disclosed motor car engine front end of the utility model train stretching wheel assembly comprises first tension arms 1 and second tension arms 2, is provided with spring 3 between said first tension arms 1 and second tension arms 2; Be provided with cavity 4 in said first tension arms 1; Be provided with bearing 5 in the said cavity 4, be fixedly connected with mandrel 6 on said second tension arms 2, said mandrel 6 is suitable with bearing 5.
Described bearing 5 can be selected for use according to actual conditions, and the preferred bearing 5 of present embodiment is the biserial angular contact bearing, and the outer end that said biserial angular contact bearing 5 cooperates with mandrel 6 is provided with nut 7, the second tension armss 2 and is fixedly clamped through the nut 7 and first tension arms 1.Said mandrel 6 is fixedly connected with second tension arms, 2 formations through burning casting.Be provided with metallic shim 8 between said second tension arms 2 and the biserial angular contact bearing 5.
In addition, described spring 3 is a torsion spring, and the middle footpath of spring is reasonable in design; Make spring when pretension, not produce friction with aluminum casting; Increase the working life of spring, because the angular contact bearing matching gap is stable, can bear bigger load simultaneously; Can not produce early stage situation about just losing efficacy, be generally 3 ~ 5 times of band plastic bushing stretching wheel assembly life-span.
The internal structure of the motor car engine front end train stretching wheel assembly of present embodiment has solved working of plastics not wear-resisting problem in stretching wheel assembly, has cancelled original riveted joint mounting type; Use the biserial angular contact bearing to solve existing stretching wheel assembly oscillating quantity problem bigger than normal; Improved the working life of stretching wheel assembly.
The foregoing description is to the specific descriptions of the utility model; Only be used for the utility model is further specified; Can not be interpreted as the qualification to the utility model protection domain, the technician of related domain according to the content of above-mentioned model utility the utility model is made some nonessential improvement and adjustment all falls within the protection domain of the utility model.
