Abstract
The invention discloses a kind of engine timing system system assembly method, it belongs to automotive field.The present invention is by the basis of traditional engine timing system system assembly method, after carrying out a timing, again bent axle and camshaft are rotated corresponding angle and carry out second time timing, thus the height of pistons all for motor in cylinder is all consistent, carry out the installment and debugging of last Timing Belt after then fixing.By such mode, the invention solves engine timing system system engine piston when Installation and Debugging and hit the risk of valve.
Description
Technical field
The present invention relates to a kind of assembly method, particularly a kind of engine timing system system assembly method, it belongs to automotive field.
Background technique
Engine timing system system needs when assembling to ensure that valve can open and close in the correct time, therefore needs accuracy when ensureing the system installation of timing system.Traditional assembling mode is in timing, crankshaft rotating is to a cylinder top dead center, such piston movement is to the top dead center of cylinder block, camshaft is rotated to valve simultaneously and be compressed into fully open position, and at positioning hole, crank pulley and camshaft pulley are fixed on above-mentioned two positions by bolt, and complete the installation of whole timing system system.After such timing system belt has assembled, in order to check running whether normal, can bent axle be rotated counterclockwise, now be easy to produce the risk that piston and valve bump against, causing valve breakage.
The open book publication number 101545384 of Chinese patent discloses a kind of assembly method of timing system of motor, timing aligning is carried out by arranging locating point on timing chain and timing sprocket, thus complete installation, the accuracy of installing can be ensured like this, but still do not solve the problem that engine piston clashes into valve possibility.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of engine timing system system assembly method that piston can be avoided to hit valve.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is:
A kind of engine timing system system assembly method, is characterized in that comprising following steps:
A, first timing system various parts to be assembled on the engine, then by crankshaft rotating to a cylinder top dead center, camshaft is rotated to valve simultaneously and is compressed into fully open position;
B, by crank pulley dextrorotation gyration 2a, make the piston in per cylinder engine be positioned at sustained height, bent axle and crank pulley relative position by calculating, and are fixed by angle 2a; By camshaft pulley dextrorotation gyration a, and camshaft and cam pulleys relative position are fixed;
C, load onto Timing Belt, automatic tensioner is adjusted to relevant position and tightens the bolt of automatic tensioner, then take out the latch of fixed crankshaft belt pulley and camshaft pulley, turn clockwise timing system system 2 circles, makes Timing Belt uniform force.
Further, described bent axle and crank pulley relative position means of fixation are: on bent axle, drive the first positioning hole, crank pulley is opened the second positioning hole, described first positioning hole and the second positioning hole carry out timing aligning at bent axle and crank pulley and just overlap after dextrorotation gyration 2a, and are fixed by latch.
Further, described camshaft and camshaft pulley relative position means of fixation are: on camshaft, drive the 3rd positioning hole, camshaft pulley is opened the 4th positioning hole, described 3rd positioning hole and the 4th positioning hole carry out timing aligning at camshaft and camshaft pulley and just overlap after dextrorotation gyration a, and are fixed by latch.
The present invention compared with prior art, have the following advantages and effect: engine timing system system assembly method is by when installation, after to complete timing, make the piston of motor all be positioned at sustained height by rotary crankshaft and camshaft again and carry out secondary timing, and then carry out the installation of Timing Belt, this avoid the risk that piston hits valve.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of engine timing system of the present invention system.
Embodiment
Below in conjunction with accompanying drawing, by embodiment, the present invention is described in further detail, and following examples are explanation of the invention and the present invention is not limited to following examples.
As shown in Figure 1, engine timing system of the present invention system is for four cylinder engine, and engine timing system system comprises camshaft pulley 1, automatic tensioner 2, oil pump belt pulley 3, idle pulley 4, crank pulley 5, water pump pulley 6, high pressure oil pump belt pulley 7.
Four cylinder engine timing system system is when assembling:
A, first the camshaft pulley 1 of timing system system, automatic tensioner 2, oil pump belt pulley 3, idle pulley 4, crank pulley 5, water pump pulley 6, high pressure oil pump belt pulley 7 to be assembled at each position on the engine, then by crankshaft rotating to a cylinder top dead center, camshaft is rotated to valve simultaneously and is compressed into fully open position;
B, crank pulley 5 dextrorotation to be turn 90 degrees, because the piston in a cylinder was in top dead center position in cylinder originally, after such rotation 90 degree, piston in motor 4 cylinders is positioned at sustained height, so just the distance between each piston and valve is zoomed out, thus ensure that piston can not collide with valve.Bent axle is opened the first positioning hole, crank pulley 5 is opened the second positioning hole, the first positioning hole and the second positioning hole carry out timing aligning and dextrorotation just overlaps after turning 90 degrees at bent axle and crank pulley 5, and are fixed by latch.Camshaft pulley 1 is turned clockwise 45 degree, and on camshaft, drive the 3rd positioning hole, camshaft pulley 1 is opened the 4th positioning hole, 3rd positioning hole and the 4th positioning hole carry out timing aligning and turn clockwise after 45 degree just overlapping at camshaft and camshaft pulley 1, and are fixed by latch;
C, load onto Timing Belt, automatic tensioner 2 is adjusted to relevant position and tightens the bolt of automatic tensioner 2, then the latch of fixed crankshaft belt pulley 5 and camshaft pulley 1 is taken out, turn clockwise timing system system 2 circles, make Timing Belt uniform force, thus complete the assembling and setting of whole engine timing system system.
Adopt technique scheme, engine timing system of the present invention system assembly method is by changing traditional timing system assembling mode, secondary timing is carried out after traditional timing, the piston of motor is all adjusted to sustained height, and then fixedly mount Timing Belt, thus avoid the piston when inspection belt condition and hit the risk of valve.
Above content described in this specification is only made for the present invention illustrating.Those skilled in the art can make various amendment or supplement or adopt similar mode to substitute to described specific embodiment; only otherwise depart from the content of specification of the present invention or surmount this scope as defined in the claims, protection scope of the present invention all should be belonged to.
