Abstract
A flywheel relates to the technical field of parts of motor vehicles and comprises a flywheel panel and a toothed pattern which are connected together. The toothed pattern is arranged on the outer side of the flywheel panel, and the connected position of the flywheel panel and the toothed pattern is provided with at least one positioning pin hole consisting of a first half hole and a second half hole, wherein the first half hole is positioned on the flywheel panel, and the second half hole is positioned on the toothed pattern. Compared with an existing flywheel, the flywheel has the advantages of high safety performance, long service life, low service cost and the like, and is suitable for popularization and utilization.
Description
Technical field
The present invention relates to Motor Vehicle component technical field, particularly a kind of flywheel.
Background technique
Flywheel is a castiron flying wheel; Its function is that the part of the energy that produces during with the motor power stroke is stored, and in order to overcome the resistance of other auxiliary stroke, makes the bent axle Rotating with Uniform; And improve the overload capacity that motor overcomes short-term, vehicle is started to walk easily.Flywheel is made up of with the tooth figure that is arranged on the Flywheel disc outside Flywheel disc, and when engine start, the starting tooth of tooth figure and motor can produce vibration in engagement process; In the course of time; Will the friction-produced gap between Flywheel disc and tooth figure, can cause tooth figure to come off when serious, damage other component; When flywheel rotates; Because there is speed discrepancy in clutch on the instantaneous and flywheel surface of separating and combine; Cause both slide relative; Make the contacted surface of flywheel and clutch friction plate produce wearing and tearing, the working life of flywheel also can have been shortened because of the local knot of ablating of the high temperature that high-speed friction produced is hard in the flywheel plane.
Summary of the invention
The present invention seeks in order to overcome above-mentioned deficiency, provide a kind of and can prevent tooth figure flywheel loosening or that come off from Flywheel disc.
For solving the problems of the technologies described above; Technological scheme of the present invention is: a kind of flywheel, comprise the Flywheel disc and the tooth figure that link together, and said tooth figure is arranged on the outside of said Flywheel disc; Said Flywheel disc is provided with at least one positioning pin hole with the position that said tooth figure is connected; Said positioning pin hole is made up of the first half holes and the second half holes, and said the first half holes are positioned on the said Flywheel disc, and said the second half holes are positioned on the said tooth figure.
As a kind of improvement, said Flywheel disc surface is provided with the protecting sheet that is used to prevent said Flywheel disc wearing and tearing, and said protecting sheet is located on said Flywheel disc and the surface that clutch friction plate contacts.Said protecting sheet is annular and is embedded on the surface of said Flywheel disc.
As further improvement, said positioning pin hole is provided with two, and the center of described two said relatively Flywheel discs of positioning pin hole is symmetrical set.
Beneficial effect of the present invention is: compare with existing flywheel; Because flywheel according to the invention is provided with positioning pin hole at Flywheel disc and tooth figure junction point; So can make Flywheel disc and tooth figure engage more fasteningly through the cooperating of locating stud and positioning pin hole, prevent that tooth figure from becoming flexible because of the vibration generation; Even the phenomenon that comes off from Flywheel disc, thereby protected other component can be loosening or come off and not damage because of tooth figure.
Owing to set up protecting sheet on the surface of Flywheel disc, reduced the friction on clutch friction plate and flywheel surface, protected the flywheel body injury-free, because protecting sheet is embedded in the Flywheel disc surface,, thereby prolonged the working life of flywheel so replacing is convenient.
In sum, flywheel according to the invention is compared with existing flywheel has the Safety performance height, long service life, and advantage such as user cost is low is suitable for promoting the use of.
Description of drawings
Accompanying drawing is a structural representation of the present invention;
Wherein: 1, Flywheel disc, 2, tooth figure, 3, positioning pin hole, 4, protecting sheet.
Embodiment
Below in conjunction with accompanying drawing and embodiment, further set forth the present invention.
Shown in accompanying drawing; A kind of flywheel comprises the Flywheel disc 1 and tooth Fig. 2 that link together, and said tooth Fig. 2 is arranged on the outside of said Flywheel disc 1; The position that said Flywheel disc 1 is connected with said tooth Fig. 2 is provided with at least one positioning pin hole 3; Said positioning pin hole 3 is made up of the first half holes and the second half holes, and said the first half holes are positioned on the said Flywheel disc 1, and said the second half holes are positioned on said tooth Fig. 2.Positioning pin hole 3 is provided with two, and the center of described two said relatively Flywheel discs of positioning pin hole 3 is symmetrical set.Can cooperating through locating stud and positioning pin hole 3; Locating stud and positioning pin hole 3 should be interference fit; Make Flywheel disc 1 and tooth Fig. 2 engage more fasteningly; Prevented that tooth Fig. 2 is loosening because of vibration produces, even the phenomenon that comes off from Flywheel disc 1, thereby protected other component can be loosening or come off and not damage because of tooth Fig. 2.
Said Flywheel disc 1 surface is provided with the protecting sheet 4 that is used to prevent said Flywheel disc 1 wearing and tearing, and said protecting sheet 4 is located on said Flywheel disc 1 and the surface that clutch friction plate contacts.Said protecting sheet 4 is an annular, is embedded on the surface of said Flywheel disc 1.Reduced the friction on clutch friction plate and flywheel surface, protected the flywheel body injury-free,,, thereby prolonged the working life of flywheel so replacing is convenient because protecting sheet 4 is embedded in Flywheel disc 1 surface.
The present invention is not limited to above-mentioned concrete mode of execution, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within protection scope of the present invention.
Claims (4)
1. flywheel; Comprise the Flywheel disc and the tooth figure that link together; Said tooth figure is arranged on the outside of said Flywheel disc, it is characterized in that: said Flywheel disc is provided with at least one positioning pin hole with the position that said tooth figure is connected, and said positioning pin hole is made up of the first half holes and the second half holes; Said the first half holes are positioned on the said Flywheel disc, and said the second half holes are positioned on the said tooth figure.
