Abstract
The utility model relates to an eccentric shaft governing device of valve clearance used by a motorcycle engine, comprising a rocker arm 1, and a rocker shaft 2. The utility model is characterized in that the rocker shaft 2 is an eccentric rocker shaft; a locking arm 3 is fixed to the rocker shaft; a plurality of locking screws 4 is positioned on the locking arm 3. The utility model has the advantages being more convenient for the governing of the valve clearance due to the adoption of the eccentric rocker shaft and the locking arm with a scale, having simple operation, being safe and reliable, meeting the needs of the users as well as saving the production cost.
Description
The utility model relates to a kind of valve clearance controlling device of motorcycle engine, particularly a kind of motorcycle engine eccentric shaft type valve clearance controlling device.
Because the temperature variation during internal combustion engine is bigger, and require very high to the seal of firing chamber, for guaranteeing the seal of firing chamber, internal-combustion engine must leave certain interval between valve and valve rocker when assembling and maintenance, and be provided with the valve clearance controlling device specially.The valve clearance controlling device of existing motorcycle engine is normally regulated by laterostigmatal adjusting screw and locking nut.Must open cylinder head cover during adjusting, regulate on request by rule of thumb or with clearance gauge, its program complexity, technical strong, make troubles for vast motorcycle user.
The purpose of this utility model is to provide a kind of motorcycle engine eccentric shaft type valve clearance controlling device simple in structure, easy and simple to handle.
The utility model is achieved in that a kind of motorcycle engine eccentric shaft type valve clearance controlling device, it comprises rocking arm, pitman arm shaft, it is characterized in that: described pitman arm shaft is eccentric pitman arm shaft, is fixed with locking arm on described pitman arm shaft, and lock screw is arranged on locking arm.
Described eccentric pitman arm shaft is made of the different axle of three sections diameters, and its first section and the 3rd section are concentric, between second section and first section, the 3rd section offset are arranged; On the eccentric pitman arm shaft seal ring is arranged.
For easy to adjust, can on locking arm, establish scale.
Described eccentric pitman arm shaft is installed on the cylinder head cover of motor, also have on the cylinder head cover with locking arm on scale regulate the benchmark boss accordingly.
Because the locking arm and the eccentric pitman arm shaft relative fixed of band scale, when the adjusting locking arm carries out the scale adjusting, eccentric pitman arm shaft rotates, drive the relative camshaft and valve motion of rocking arm, the valve clearance is increased or reduce, by calculating and experiment,, the valve clearance is adjusted to suitable size back locks with lock screw with the size of valve clearance and the scale correspondence on the locking arm.
The utility model has been cancelled valve adjustments screw and adjusting nut, eccentric pitman arm shaft and dial have been adopted, need not open cylinder head cover when regulating the valve clearance like this, directly unscrewing lock screw regulates by the ground of the scale intuitive and convenient on the locking arm, and can when engine running, regulate, more help reducing the engine valve noise.In a word, the utility model is simple in structure, and than the more convenient easy row of traditional valve adjustments mode, easy and simple to handle, safe and reliable.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1, the utility model embodiment's structural representation;
The structural representation of Fig. 2, cylinder head cover;
Fig. 3, the utility model embodiment's use installation diagram.
Referring to above-mentioned accompanying drawing as can be known: a kind of motorcycle engine eccentric shaft type valve clearance controlling device, it comprises rocking arm 1, pitman arm shaft 2, it is characterized in that: described pitman arm shaft 2 is eccentric pitman arm shaft, is fixed with locking arm 3 on described pitman arm shaft 2, and lock screw 4 is arranged on locking arm 3.
Described eccentric pitman arm shaft 2 is made of the different axle of three sections diameters, and its first section and the 3rd section are concentric, between second section and first section, the 3rd section offset are arranged; On the eccentric pitman arm shaft 2 seal ring 5 is arranged.
For easy to adjust, can on locking arm 3, establish scale.
Described eccentric pitman arm shaft 2 is installed on the cylinder head cover 6 of motor, also have on the cylinder head cover 6 with locking arm 3 on scale regulate benchmark boss 7 accordingly.
