Abstract
The utility model discloses a valve push rod, which mainly comprises a rod body, a round push rod head, a retaining shoulder of the push rod head, the retaining shoulder of a push rod tail, a flat base of the push rod tail and an oil hole. The two ends of the rod body are respectively provided with the round push rod head and the flat base of the push rod tail, the retaining shoulder of the push rod head is arranged at the round push rod head, a groove is arranged at the connection part of the round push rod head and the retaining shoulder of the push rod head, the retaining shoulder of the push rod tail is arranged at the flat base of the push rod tail, and similarly, a groove is arranged at the connection part of the flat base of the push rod tail and the retaining shoulder of the push rod tail. The rod body is axially provided with the oil hole, and the oil hole penetrates through the whole rod body.
Description
(1) technical field
The utility model relates to engine art, is specifically related to a kind of valve actuating push rod of motor inlet and outlet door controlling device.
(2) background technique
The engine valve regulating system is one of important device in the engine control parts, in the distribution device of motor, the effect of pneumatic door control system is according to the job order of motor and working procedure, time opening and close intake valve or exhaust valve, make inflammable mixture or air enter cylinder, and waste gas is discharged.The distribution device of motor generally is made up of timing gear, peach oblique crank Z, valve actuating push rod, pitman arm shaft (seat), rocking arm, intake valve, intake valve return spring and valve tappet etc.Timing gear at first drives the rotation of peach oblique crank Z, eccentric wheel out of phase on the peach oblique crank Z arranges that corresponding with the phase place of bent axle motion, the peach oblique crank Z promotes valve actuating push rod simultaneously, valve actuating push rod promotes rocking arm one end, make the rocking arm the other end depress intake valve and intake valve return spring, intake valve is opened, this moment, cylinder was just finished the process of an air inlet, simultaneously when valve actuating push rod resets and drive the rocking arm return, intake valve resets under the return spring effect, IC Intake Valve Closes, and the on-off action of exhaust valve is also identical.Because the working environment of parts is complicated in the motor, requirement to aspects such as the serviceability of part and reliabilities is all quite high, when valve actuating push rod turns round in high engine speeds, the operating frequency height, therefore valve actuating push rod must have certain fastness, also need consider simultaneously valve actuating push rod rationality structurally, to guarantee the reliable of engine valve on-off action.
(3) summary of the invention
The utility model mainly provides a kind of novel valve actuating push rod, and main technical schemes is as follows:
A kind of valve actuating push rod mainly comprises the body of rod, circular push rod cup, push rod cup shoulder block, push rod tail shoulder block, push rod tail flat bed, oil-through hole.Described body of rod two ends are respectively circular push rod cup and push rod tail flat bed, circular push rod cup place is provided with the push rod cup shoulder block, circular push rod cup and push rod cup shoulder block joint are provided with a groove, described push rod tail flat bed place is provided with push rod tail shoulder block, is provided with a groove at push rod tail flat bed and push rod tail shoulder block joint equally.The body of rod axially be provided with an oil-through hole, oil-through hole runs through the whole body of rod.
Valve actuating push rod described in the utility model adopts stainless steel and makes through the integrated type processing mode, and push rod cup is handled through surface hardness, has higher wear resistance.The push rod cup of globular model design can well contact with the rocking arm pole socket, and the friction noise when helping reducing work.The shoulder block that is provided with in two end joints is used for the connection of link, and the groove of setting is used for the location of rubber ring.The oil-through hole that body of rod center is provided with can make the interior unnecessary greasing substance of rocking arm pedestal in time reclaim by this oil-through hole, can keep the cleaning of upper unit.
(4) description of drawings
Accompanying drawing is the structural representation of valve actuating push rod
(5) embodiment
As shown in drawings, a kind of valve actuating push rod described in the utility model mainly comprises the body of rod 1, circular push rod cup 3, push rod cup shoulder block 2, push rod tail shoulder block 4, push rod tail flat bed 5, oil-through hole 6.The two ends of the described body of rod 1 are respectively circular push rod cup 3 and push rod tail flat bed 5, circular push rod cup 3 places are provided with push rod cup shoulder block 2, circular push rod cup 3 is provided with a groove with the joint of push rod cup shoulder block 2, described push rod tail flat bed 5 places are provided with push rod tail shoulder block 4, are provided with a groove in the joint of push rod tail flat bed 5 and push rod tail shoulder block 4 equally.The body of rod 1 axially be provided with an oil-through hole 6, oil-through hole 6 is through the whole body of rod 1.
Claims (1)
1. valve actuating push rod, comprise the body of rod, circular push rod cup, push rod cup shoulder block, push rod tail shoulder block, push rod tail flat bed, oil-through hole, it is characterized in that: body of rod two ends are respectively circular push rod cup and push rod tail flat bed, described circular push rod cup place is provided with the push rod cup shoulder block, circular push rod cup and push rod cup shoulder block joint are provided with a groove, described push rod tail flat bed place is provided with push rod tail shoulder block, be provided with a groove at push rod tail flat bed and push rod tail shoulder block joint equally, the described body of rod axially be provided with an oil-through hole, and oil-through hole runs through the whole body of rod.
