Abstract
A motorcycle engine timing camshaft, a left sliding shaft sleeve (7) and a right sliding shaft sleeve (8) are respectively arranged on a timing camshaft (1), and the left end of the timing camshaft (1) is fixedly connected with a gear (9). A driven chain wheel fixed disk (2) is fixedly arranged on the timing camshaft (1) and is positioned at the left side of the left sliding shaft sleeve (7); a positioning step (5) is arranged on the driven chain wheel fixed disk (2), at least two screws (6) are arranged on a disk body, a shaft center hole (11) of a driven chain wheel (3) is sleeved on the positioning step (5) which is arranged on the driven chain wheel fixed disk (2) and is fixedly connected with the driven chain wheel fixed disk (2) through a bolt. The utility model can not only be beneficial to the assembly and disassembly of the timing chain and prolong the service life of the timing chain, but can also ensure the stability.
Description
(1) technical field
The utility model relates to a kind of motorcycle engine timing camshaft, relates in particular to a kind of split type timing camshaft of motorcycle engine of being convenient to the timing chain assembling.
(2) background technique
At present, GN/GS125-2 series motorcycle motor generally adopts the integrated type timing camshaft, because timing driven sprocket and timing camshaft are as a whole, though stability is guaranteed, but during the assembling timing chain, can only timing chain be contained on the timing driven sprocket earlier, timing camshaft is installed again, this has just limited the sphere of activities when timing camshaft is installed, cause the assembling difficulty, dismounting is inconvenient, and the easy damaged timing chain, influences its working life.
(3) summary of the invention
The purpose of this utility model provides a kind of motorcycle engine timing camshaft, and it had both helped the assembling and the dismounting of timing chain, can prolong the working life of timing chain, and stability is guaranteed.
For reaching above-mentioned purpose, the utility model is fixedly installed on the driven sprocket fixed tray on the timing camshaft, is positioned at the left side of left sliding shaft sleeve.The driven sprocket fixed tray is provided with positioning step, and disk body is provided with at least two screws.The axle center hole of driven sprocket is enclosed within on the positioning step on the driven sprocket fixed tray, and fixedlys connected with the driven sprocket fixed tray by bolt.
Owing to adopted said structure, the timing driven sprocket is dismountable parts, during assembling, because of the aperture, axle center of timing driven sprocket greater than the diameter of gear and the diameter of axle of timing camshaft, the driven sprocket of loading onto chain can move between timing camshaft and driven sprocket fixed tray positioning step, make timing chain be convenient to assembling and dismounting, not easy damaged chain.And fixedly connected with the driven sprocket fixed tray by bolt because of driven sprocket, stability is guaranteed.
The utility model is described in further detail below in conjunction with drawings and Examples.
(4) description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is a driven sprocket structure diagram of the present utility model.
(5) embodiment
Referring to Fig. 1, Fig. 2, be respectively equipped with left sliding shaft sleeve 7, right sliding shaft sleeve 8 on the timing camshaft 1, timing camshaft 1 left end is fixedlyed connected with gear 9.Driven sprocket fixed tray 2 is fixedly installed on the timing camshaft 1, is positioned at the left side of left sliding shaft sleeve 7.Driven sprocket fixed tray 2 is provided with positioning step 5, and positioning step 5 diameters of axle are greater than the diameter of gear 9 and the diameter of axle 4 of close gear 9 place's timing camshafts 1.Driven sprocket fixed tray 2 disk bodies are provided with two screws 6 of symmetry.The axle center hole 11 of driven sprocket 3 is enclosed within on the positioning step 5 on the driven sprocket fixed tray 2.Also be provided with on the driven sprocket 3 with driven sprocket fixed tray 2 on two screw 6 corresponding holes 10, and be fastenedly connected by bolt and driven sprocket fixed tray 2.
During assembling, earlier timing driven sprocket 3 is enclosed within on the diameter of axle 4 between gear 9 and the driven sprocket fixed tray 2, puts timing chain then.The timing camshaft 1 that puts timing driven sprocket 3 and timing chain is packed in the cylinder head camshaft hole, again timing chain is contained on the driven sprocket 3 by the timing position, and the driven sprocket 3 that will install timing chain is enclosed within on the positioning step 5 of driven sprocket fixed tray 2, with bolt driven sprocket 3 is fastened on the driven sprocket fixed tray 2 at last.During dismounting, reverse operating can be pulled down timing chain and timing camshaft 1 easily.
When engine operation, timing camshaft 1 drives the timing chain motion, gives wheel with the power normal delivery.
Claims (4)
