Abstract
The utility model discloses a rocker arm part of an air inlet door, which mainly comprises a rocker arm main rod, a rotating shaft hole, a rocker arm front rod, a wear-resistant contact, a push rod connecting seat, a push rod connecting screw hole, an oil injection hole, an inner lubricating oil tube hole and a marking surface. The rotating shaft hole is arranged on the lower portion of the rocker arm main rod, the rocker arm front rod is disposed on one side of the rocker arm main rod, and the wear-resistant contact is disposed below an arc-shaped head. The push rod connecting seat is arranged on the other side of the rocker arm main rod, and the push rod connecting screw hole is arranged in the push rod connecting seat. The oil injection hole is obliquely arranged on a rod surface on the upper side of the rocker arm main rod, and the other end of the oil injection hole is arranged in the rotating shaft hole. Simultaneously, the inner lubricating oil tube hole is designed between the rotating shaft hole and the push rod connecting screw hole, and accordingly residual lubricating oil in the rotating shaft hole is automatically squeezed into the push rod connecting seat.
Description
(1) technical field
The utility model relates to engine art, is specifically related to a kind of rocker arrangement that can accurately regulate the engine charge door device.
(2) background technique
The engine valve rocker member is one of important device in the engine control parts, in the distribution device of motor, the effect of intake valve control system is according to the job order of motor and working procedure, and time opening and close intake valve makes inflammable mixture or air enter cylinder.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 is arranged, corresponding with the phase place of bent axle motion, the peach oblique crank Z promotes valve actuating push rod simultaneously, and 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, and 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.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, the combination rocker member that many band roller touch devices are arranged in the market, though usability is better, but price is more expensive, and touches roller in actual use and easily lost efficacy under the high operating frequency and the condition of high temperature.Consider the cost performance of part, therefore provide a kind of inlet valve rocker device rational in infrastructure, easily manufactured and that usability is superior to be necessary very much.
(3) summary of the invention
The utility model mainly provides a kind of novel inlet valve rocker spare, and main technical schemes is as follows:
A kind of inlet valve rocker spare mainly comprises rocking arm mobile jib, rotary shaft hole, the preceding bar of rocking arm, wear-resisting contact, push rod connecting base, push rod connecting screw hole, oil hole, interior lubricant oil pore, identified surface.Rotary shaft hole is arranged on the bottom of rocking arm mobile jib, and the pedestal of rotary shaft hole forms two convex shoulders in the bottom of rocking arm mobile jib, and bar is located at one side of rocking arm mobile jib before the rocking arm, and is designed to a downward arc shape, is provided with wear-resisting contact in the lower head of arc shape.
The another side of described rocking arm mobile jib is provided with the push rod connecting base, is provided with push rod connecting screw hole in the push rod connecting base.
Lubrication effect when guaranteeing that inlet valve rocker spare rotates on pitman arm shaft, the utility model are oblique on body of rod face above the rocking arm mobile jib to be provided with an oil hole, and the other end of oil hole is in rotary shaft hole.Simultaneously, for making things convenient for valve actuating push rod lubricating in the push rod connecting base, the utility model has specially designed an interior lubricant oil pore between rotary shaft hole and push rod connecting screw hole, and the interior unnecessary lubricant oil of rotary shaft hole is automatically pressed in the push rod connecting base.
The utility model is the sign that makes things convenient for different model valve rocker spare, is provided with the identified surface of two spills on the side body of rod positive and negative of spy's bar before rocking arm, can be used for the sign of fonts such as model, trade mark.
Technological scheme described in the utility model compared with prior art, its effect is actively and significantly.Whole rocker member adopts casting forming, the wear-resisting contact of bar adopts alloy steel material before the described rocking arm, and after surface heat is handled, make it have certain rigidity and wear resistance, can in high-frequency IO Intake Valve Opens action, keep serviceability, and under hot environment, be difficult for losing efficacy.The interior lubricant oil pore of the utility model unique design can make the intercommunication that is lubricated material between rotary shaft hole and the push rod connecting screw hole, has save the trouble of specially intake valve push rod connection part being added greasing substance.

(5) embodiment
As shown in drawings, a kind of inlet valve rocker spare described in the utility model has mainly comprised rocking arm mobile jib 1, rotary shaft hole 2, the preceding bar 3 of rocking arm, wear-resisting contact 4, push rod connecting base 5, push rod connecting screw hole 6, oil hole 7, interior lubricant oil pore 8, identified surface 9.Rotary shaft hole 2 is arranged on the bottom of rocking arm mobile jib 1, and the pedestal of rotary shaft hole 2 forms two convex shoulders in the bottom of rocking arm mobile jib 1; bar 3 is located at one side of rocking arm mobile jib 1 before the rocking arm, and is designed to a downward arc shape, is provided with wear-resisting contact 4 in the lower head of arc shape.
The another side of described rocking arm mobile jib 1 is provided with push rod connecting base 5, is provided with push rod connecting screw hole 6 in push rod connecting base 5.
Lubrication effect when guaranteeing that inlet valve rocker spare rotates on pitman arm shaft, the utility model are oblique on body of rod face above the rocking arm mobile jib 1 to be provided with an oil hole 7, and the other end of oil hole 7 is in rotary shaft hole 2.Simultaneously, for making things convenient for valve actuating push rod lubricating in push rod connecting base 5, the utility model has specially designed an interior lubricant oil pore 8 between rotary shaft hole 2 and push rod connecting screw hole 6, and rotary shaft hole 2 interior unnecessary lubricant oil are automatically pressed in the push rod connecting base 5.
The utility model is the sign that makes things convenient for different model valve rocker spare, is provided with the identified surface 9 of two spills on the side body of rod positive and negative of spy's bar 3 before rocking arm, is used for the sign of fonts such as model, trade mark.
