Abstract
The utility model discloses a pressure-reducing device for a motorcycle. The pressure-reducing device belongs to pressure-reducing devices and structurally comprises a drive rod, a cam shaft, a cam chain wheel flail block, a rocker arm and a mandril pin; the cam shaft and the rocker arm are arranged on a bracket; the drive rod is arranged in the cam shaft; the mandril pin and the cam chain wheel flail block are respectively arranged at the two sides of the drive rod; a bulge pin is arranged on the cam chain wheel flail block; a clamping groove is arranged at the lower part of the drive rod; the bulge pin is arranged in the clamping groove; and the cam chain wheel flail block and the drive rod are connected with the bulge pin in a matching way by the clamping groove. Compared with the prior art, the pressure-reducing device for the motocycle has the characteristics that the bulge pin is arranged on the cam chain wheel flail block, and the clamping groove is arranged on the drive rod, so that the machining cost and the machining procedures are reduced, the pressure load borne by the drive body is reduced, and the strength is increased; and therefore, the pressure-reducing device has better promotion and application values.
Description
Technical field
The utility model relates to a kind of decompressor, and especially a kind of motorcycle is used decompressor.
Background technique
Present employed decompressor on the motorcycle, drive link and cam sprocket wheel get rid of piece transmission employing is that the transmission lever pin gets rid of the piece groove with decompression and cooperates, and the transmission lever pin is arranged on the drive link; Be cam pin, the cam sprocket wheel get rid of having on the piece decompression get rid of the piece groove, when motor does work; The cam sprocket wheel gets rid of piece and drives the drive link rotation; Simultaneously stressed because of drive link two ends cam pin, motor turns round several thousand times repeatedly, and the transmission lever pin just is easy to break.The transmission lever pin is a cam pin, and with domestic level of processing, the machining difficulty is big, processing cost is high.Mostly existing domestic this design is casting processing or forges processing that the exemplar strength grade that processes is lower.At present, good solution is not also arranged.
The model utility content
The technical assignment of the utility model is to provide a kind of motorcycle to use decompressor to above-mentioned deficiency of the prior art; This a kind of motorcycle has the cam sprocket wheel got rid of with decompressor raised pin is set on the piece; Have draw-in groove on the drive link; Reduce processing cost and work flow, alleviated the suffered pressure loading of drive link itself, increased the characteristics of intensity.
The utility model solves the technological scheme that its technical problem adopted: it comprises that drive link, camshaft, cam sprocket wheel get rid of piece, rocking arm and crown bar pin; Described camshaft and rocking arm are arranged on the support; Described drive link is arranged in the camshaft; Described crown bar pin and cam sprocket wheel get rid of the both sides that piece is separately positioned on drive link, and described cam sprocket wheel gets rid of piece and is provided with raised pin, and the bottom of described drive link is provided with draw-in groove; Described raised pin is arranged in the draw-in groove, and described cam sprocket wheel gets rid of piece and is connected with the raised pin cooperation through draw-in groove with drive link.
A kind of motorcycle of the utility model is compared with existing technology with decompressor; Has following outstanding beneficial effect: the cam sprocket wheel is got rid of raised pin is set on the piece, have draw-in groove on the drive link, reduced processing cost and work flow; Alleviated the suffered pressure loading of drive link itself; Increased intensity, strengthened the working life of the mechanism of decompressor itself, characteristics such as easy to use.

Embodiment
Explanation at length below doing with decompressor with reference to a kind of motorcycle of Figure of description 1, accompanying drawing 2 and 3 pairs of the utility model of accompanying drawing.
A kind of motorcycle of the utility model is used decompressor; Its structure comprises that drive link 1, camshaft 3, cam sprocket wheel get rid of piece 2, rocking arm 6 and crown bar pin 5; Described camshaft 3 is arranged on the support 4 with rocking arm 6, and described drive link 1 is arranged in the camshaft 3, and described crown bar pin 5 gets rid of the both sides that piece 2 is separately positioned on drive link 1 with the cam sprocket wheel; Described cam sprocket wheel gets rid of piece 2 and is provided with raised pin 7; The bottom of described drive link 1 is provided with draw-in groove 8, and described raised pin 7 is arranged in the draw-in groove 8, and described cam sprocket wheel gets rid of piece 5 and is connected with raised pin 7 cooperations through draw-in groove 8 with drive link 1.
In motor when acting,, the cam sprocket wheel gets rid of piece 2 and rotates, and the raised pin 7 of getting rid of on the piece 2 through the cam sprocket wheel cooperates with draw-in groove 8 on the drive link 1, drives drive link 1 and rotates, thereby crown bar pin 5 is ejected along camshaft 3 diametric(al)s, and drive rocking arm 6 moves.
Except that the described technical characteristics of specification, be the known technology of those skilled in the art.
