Abstract
The utility model relates to a spring push rod gas inlet and exhausting mechanism for an IC engine. The mechanism comprises a cam, a tappet, a push rod, a sleeve pipe, a cylinder cover body, a valve rocker, a spring upper seat, a valve spring, a spring lower seat, a catheter and a valve rod. A damping rubber block (3) is arranged between the push rod (4) and station holes of the tappet (2), the lower end of the plunger (4) is wrapped with a spring (5) which is arranged between the sleeve pipe (6) and station holes of the tappet. The utility model changes the shock contact movement among the cam, the tappet and the push rod to the damping movement, reduces the sports wear of the mechanism, eliminates the impact vibration noise, and causes engine to do work in the groove.
Description
The utility model belongs to mechanical field, particularly relates to a kind of internal combustion engine air-exhausting air-entering mechanism.
Existing internal-combustion engine push rod intake and exhaust mechanism collides at push rod and tappet and connects the position damping blob of viscose is not set, and does not have damping spring between sleeve pipe and the tappet, and valve stem and valve rocker directly bump and connect.When cam rotates to the convex surface extreme lower position, produce certain clearance between tappet, push rod, the valve rocker, when cam rotates near boss, push away (enduring) bar and cam because of rotational speed, inertia make and produce impact.Frequent impact easily causes cam-surface wear, causes valve lift height to change, and occurs during air valve drop impacting, and rocking arm and valve tail end can produce big noise.The valve tappet characteristics of motion is damaged and will directly causes engine power to descend.
The purpose of this utility model is to overcome the deficiencies in the prior art part, a kind of improved spring push rod intake and exhaust mechanism is provided, distribution device is reduced wear and eliminate the mechanism kinematic noise, the anti-effectively half-open semi-closure of air-stop gate, reach no impact conditions, thereby guarantee that motor is in optimum Working.
The technical solution of the utility model is such.This push rod intake and exhaust mechanism comprises cam, tappet, push rod, sleeve pipe, cylinder body, valve rocker, the spring seat of honour, valve spring, spring lower seat, conduit and valve stem.Casing pipe sleeve is contained on the push rod, and the lower end of push rod is arranged in the platform hole of tappet, and upper end and valve rocker one side rocking arm are collided and connect, spring lower seat and cylinder body overlap joint.Being arranged in the valve stem of guide rod and the opposite side rocking arm of valve rocker joins.It is characterized in that: between push rod and the tappet platform hole damping blob of viscose is housed, the lower end of push rod is wound with spring, and spring is between sleeve pipe and tappet bore platform.Blob of viscose and spring assembly are set, impact in the time of can alleviating tappet, push rod and valve motion, and can abate the noise.The adjustment nut that is used to adjust the sleeve pipe shift length is equipped with at the push rod position that is positioned at cannula tip.When need adjusting valve, unclamp and adjust nut and can make and move certain distance on the sleeve pipe.On the opposite side rocking arm of valve rocker the adjustment screw is housed, valve stem is connected with the adjustment screw by contiguous block.This mechanism in the course of the work, when cam rotated to extreme lower position, spring between tappet and the push rod and damping blob of viscose were played a role, rocking arm and valve stem top are closely linked, and do not produce impact each other.Tappet and the displacement of cam rotation routing motion are moderate, are similar to mild gliding motility.
The utility model is compared with existing push rod intake and exhaust mechanism, and the impact contact movement between cam, tappet, the push rod is become kicking motion, has alleviated the mechanism kinematic wearing and tearing, has eliminated the impact endurance test shock noise, makes the motor work done be in the optimum state.
Embodiment of the present utility model is illustrated in conjunction with the accompanying drawings.
Fig. 1 is a structural representation of the present utility model.
As shown in the figure, each component of the present utility model are: 1-cam, 2-tappet, 3-damping blob of viscose, 4-push rod, 5-spring, 6-sleeve pipe, 7-cylinder body 8-adjustment nut 9-valve rocker 10-adjustment screw 11-contiguous block 12-spring seat of honour 13-valve spring, 14-spring lower seat, 15-conduit, 16-valve stem
As can be seen, sleeve pipe (6) is sleeved on the push rod (4) from the figure, and the lower end of push rod (4) is positioned at the platform hole of tappet (2), and upper end and valve rocker (9) one side rocking arms are collided and connect.Spring lower seat (14) and cylinder body (7) overlap joint.Being arranged in the valve stem (16) of conduit (15) and the opposite side rocking arm of valve rocker (9) joins.Between push rod (4) and tappet (2) platform hole damping blob of viscose (3) is housed, the lower end of push rod (4) is wound with spring (5), and spring (5) is positioned between sleeve pipe (6) and the tappet bore platform.The adjustment nut (8) that is used to adjust the sleeve pipe shift length is equipped with at push rod (4) position that is positioned at sleeve pipe (6) top.When needing to adjust valve, unclamp and adjust nut (8), make on the sleeve pipe (6) and move certain distance, spring this moment (5) is inoperative; Valve rocker (9) produces the gap with valve stem (16) top, after the gap adjustment regulation, will adjust nut (8) to downward modulation, and sleeve pipe (6) is moved down, and at this moment spring can play the pretension effect.Be equipped with on the opposite side rocking arm of valve rocker (9) and adjust screw (10), valve stem (16) is connected with adjustment screw (10) by contiguous block (11), the connecting end of the adjustment screw (10) that joins with contiguous block (11) is the ball-type shape, and wearing and tearing evenly are convenient to adjust in the motion.
