The application provides a hydraulic tappet valve rocker composite set can reduce the horizontal frictional force that the valve bridge received, reducing wear.
Referring to fig. 1, the hydraulic tappet valve rocker arm assembly of the present application includes: the device comprises a rocker shaft 1, a valve rocker 2, a hydraulic tappet 3, a roller 4 and a valve bridge 5;
the valve rocker 2 is sleeved on the rocker shaft 1 and is used for swinging by taking the axis of the rocker shaft 1 as a shaft and the arm length of the valve rocker 2 as a radius; the hydraulic tappet 3 is arranged at one end of the valve rocker 2; the roller 4 is arranged at the lower end of the hydraulic tappet 3; the top of the valve bridge 5 is provided with a contact plane 51, the contact plane 51 is in contact with the hydraulic tappet 3 through the roller 4, and when the hydraulic tappet 3 abuts against the contact plane 51, the valve bridge 5 is driven to roll on the contact plane 51 by taking the central axis of the roller 4 as an axis when moving along with the hydraulic tappet 3.
The hydraulic tappet valve rocker arm combination device in this application drives through the engine in practical application, and the bent axle of engine is rotatory under the effect of piston to utilize the gear to drive the camshaft rotatory, drive the cam rotation, and this cam supports ejection valve rocker arm 2 constantly, through the rotation of the protruding department of cam, can make this valve rocker arm 2 use rocking arm axle 1 as the axle, carry out the swing of the half arc orbit of radius for valve rocker arm 2's arm length.
Optionally, the hydraulic tappet valve rocker arm combination device further comprises: the two ends of the bottom of the valve bridge 5 are provided with valve grooves, the valve heads of the valves 6 are arranged in the valve grooves, and the valves 6 can move together with the valve bridge 5.
When the valve rocker 2 swings downwards, the hydraulic tappet 3 positioned at one end of the valve rocker 2 is driven, acting force is acted on a contact plane 51 at the top of the valve bridge 5 through the hydraulic tappet 3, and then the acting force is transmitted to the valve 6 on the engine, so that the valve 6 moves downwards under the action of the acting force to realize the opening of the valve, meanwhile, the valve 6 is provided with a return spring in a matching way, the upward elastic force of the return spring is smaller than the downward acting force in the process, and the contraction elastic deformation is generated; when the rocker arm 2 of the valve 6 swings upwards, the return spring is fixed on the fixed supporting seat, so that the upward elastic force of the return spring is larger than the downward acting force of the valve bridge 5 acting on the return spring, and further acts on the valve bridge 5, and the valve bridge 5 and the valve 6 arranged on the valve bridge 5 move upwards to close the valve 6.
When the engine is operating, the valve 6 will expand due to the increase in temperature. If there is no gap or too small gap between the valve 6 and its transmission part in cold state, the valve 6 is not closed tightly because of the thermal expansion of the valve 6 and its transmission part in hot state, and the engine leaks air in compression stroke and working stroke, so the power is reduced, and even it is not easy to start in serious condition. In order to eliminate this phenomenon, a certain clearance is usually left in the valve 6 and its transmission mechanism during cold engine assembly to compensate for the amount of expansion of the valve 6 after heating, and this clearance is called valve clearance.
The hydraulic tappet 3 is sleeved on the valve rocker 2, and the valve bridge 5 is driven to move up and down by contacting the hydraulic tappet 3 with the valve bridge 5, so that a valve 6 connected with the valve bridge 5 is driven to move up and down. When the temperature is changed, the pressure in the hydraulic tappet 3 changes, and because engine oil in the hydraulic tappet 3 is difficult to compress and leaks and the principle of replenishment in the hydraulic tappet is propped up, thereby changing the engine oil pressure in the 3 intracavity of hydraulic tappet and just can changing the working length of the hydraulic tappet of hydraulic tappet 3, thereby playing the effect of automatically adjusting the valve clearance, can make between the valve rocker 2 and the driving movable piece valve bridge 5 needn't adjust the valve clearance again.
However, during the above operation, since the rocker arm 2 swings up and down with the axis of the rocker shaft 1 as the axis and the rocker arm 2 as the radius, i.e. not exactly vertically, there is a lateral force, which may result in a variation of the contact point of the pressure head of the valve rocker 2 with the contact plane 51 at the top of the valve bridge 5, that is, the position of the contact point of the hydraulic tappet 3 with the contact plane 51 at the top of the valve bridge 5 is displaced not only vertically, but also horizontally, i.e. a lateral relative sliding between the hydraulic tappet of the hydraulic tappet 3 and the contact plane 51 of the valve bridge 5, this valve bridge is thus subjected to lateral frictional forces which may be transmitted via the valve bridge 5 to the valve 6 and ultimately to the valve guide or valve seat insert of the fixed valve 6, resulting in lateral eccentric wear between the valve 6 and the fixed valve guide or valve seat insert. In this application, set up gyro wheel 4 at the lower extreme of this hydraulic tappet 3, contact plane 51 through gyro wheel 4 and this valve bridge 5 top is supported, utilize rolling frictional force to replace sliding frictional force, from the analysis in principle of frictional force, the friction factor of rolling frictional force is less than the friction factor of sliding frictional force, when the effort that receives hydraulic tappet 3 on the valve bridge 5 is a definite value, through the general frictional force calculation method of object, the product of dynamic frictional factor and the normal pressure that receives promptly equals sliding frictional force, can learn, set up the horizontal effort that this gyro wheel 4 can reduce between hydraulic tappet 3 and the valve bridge 5 in this application, promptly horizontal frictional force.
Alternatively, the structure of the head portion of the valve 6 is a flat top structure. In the embodiment, the flat-top valve head has the advantages of simple structure, convenience in manufacturing, small heat absorption area and small mass, and the inlet valve and the exhaust valve can use the head structure.
Optionally, the centre axis of the valve 6 is perpendicular to the contact plane 51. When the valve 6 is arranged in the grooves at the two ends of the valve bridge 5, the central axis of the valve 6 is perpendicular to the contact plane 51 of the valve bridge 5, so that the direction of the acting force transmitted from the roller 4 on the valve bridge 5 on the valve 6 is perpendicular to the central axis of the valve 6 and the contact plane 51, and the problem of eccentric wear caused by overlarge transverse acting force between the valve 6 and a valve guide pipe or a valve seat ring can be reduced.
Alternatively, the central axis of the roller 4 is parallel to the axis of the rocker shaft 1. When the central axis of the roller 4 is not parallel to the axis of the rocker shaft 1, the internal acting force of the roller 4 connected inside the hydraulic tappet 3 and the acting force of the roller 4 acting on the contact plane 51 of the valve bridge 5 may not be on the plane of the swing arc track, which may cause unbalanced acting force applied to both ends of the roller 4 and fixed at the lower end of the hydraulic tappet 3 inside the hydraulic tappet 3, and the roller 4 may be damaged easily.
Optionally, the central axis of the roller 4 is parallel to the contact plane 51. The roller 4 rolls along the central axis of the roller 4, and when the central axis of the roller 4 is parallel to the contact plane 51, the rolling surface of the roller 4 can be matched with the contact plane 51, so that the internal acting force of the hydraulic tappet 3, which is connected with the roller 4, and the valve bridge 5 act on the plane where the reaction force of the roller 4 is located on the swing arc track, and the problem that the roller 4 is damaged due to the internal connecting acting force is solved.
Optionally, the length of the contact plane 51 is greater than the length of the rolling path of the roller 4, and the width of the contact plane 51 is greater than the width of the rolling surface of the roller 4. The length of the contact plane 51 is larger than that of the rolling path of the roller 4, the rolling path is reserved for the rolling of the roller 4, and the problem that the roller 4 rolls out of the contact plane 51 due to the shaking of the valve rocker 2 or the loose of combined parts, so that the hydraulic tappet 3 and the valve bridge are damaged due to the fault 5 can be reduced.
Alternatively, the hydraulic tappet 3 is arranged in a tappet housing 7, the tappet housing 7 is arranged at the end of the valve rocker 2, and the tappet housing 7 and the hydraulic tappet 3 can move together with the valve rocker 2. Through the tip at hydraulic tappet 3 and valve rocker 2 sets up tappet shell 7, can protect hydraulic tappet 3 and this valve rocker 2's end connection department, can reduce because the temperature of this junction differs other problems such as too big with the outside temperature, the dust or the ponding scheduling problem that lead to.
Optionally, the rolling surface of the roller 4 is a plane. Because of the interaction of the forces, when the roller 4 is abutted against the contact plane 51, the roller is subjected to the reaction force on the valve bridge 5, and when the rolling surface of the roller 4 is a plane, compared with the case that the rolling surface is a non-plane, the stress area between the roller 4 and the contact plane 51 can be increased, the pressure applied to the roller 4 can be reduced, and thus the requirements of hardware performance in the aspects of the pressure applied to the roller 4 and the like can be reduced.
Optionally, the contact plane 51 is provided with a lubricant, which can reduce the dynamic friction factor of the contact plane 51 on the top of the valve bridge 5, thereby reducing the lateral friction force to which the valve bridge 5 is subjected, and further reducing the lateral friction force to which the valve 6 is subjected, and reducing the problem of lateral eccentric wear due to the lateral force between the valve 6 and the valve guide or the valve seat insert.
Optionally, a hydraulic tappet 3 is also installed between the valve rocker 2 and the cam, so that the cam on the cam shaft constantly abuts against the hydraulic tappet 3, the protruding part of the cam is utilized to drive the hydraulic tappet 3 and the corresponding push rod to move up and down, and the valve rocker 2 connected with the hydraulic tappet 3 is driven to reciprocate up and down by taking the rocker shaft 1 as an axis. In this embodiment, through installing hydraulic tappet 3 between valve rocker 2 and cam, when the inside temperature variation of hydraulic tappet 3, just can change the working length of hydraulic tappet through the machine oil pressure that changes the tappet body intracavity to play the effect of automatic adjustment valve clearance, can be so that need not adjust valve clearance again between valve rocker 2 and the cam.
It should be noted that the above summary and the detailed description are intended to demonstrate the practical application of the technical solutions provided in the present application, and should not be construed as limiting the scope of the present application. Various modifications, equivalent substitutions, or improvements may be made by those skilled in the art within the spirit and principles of the present application.
