Abstract
The utility model discloses a rocker piece of an exhaust valve, which mainly comprises a rocker main rod, a rotating shaft seat, a rotating shaft hole, a front rod of a rocker, a wear-resistant contact head, a connection seat of a push rod, a connection screw hole of the push rod, an oil charging hole, an inner lubricating oil pipe hole and a marking side. The rotating shaft seat is arranged at the lower part of the rocker main rod, the rotating shaft hole is arranged in the rotating shaft seat, the front rod of the rocker is arranged at one side of the rocker main rod, and the lower part of the head part of the front rod of the rocker is provided with the wear-resistant contact head. The other side of the rocker main rod is provided with the connection seat of the push rod, and the connection screw hole of the push rod is arranged in the connection seat of the push rod. In order to ensure the lubricating effect when the rocker piece of the exhaust valve rotates on a rockshaft, the oil charging hole is obliquely arranged on the upper rod body side of the rocker main rod, the other end of the oil charging hole is arranged in the rotating shaft hole, the inner lubricating oil pipe hole is also designed between the rotating shaft hole and the connection screw hole of the push rod, so the redundant lubricating oil in the rotating shaft hole can be automatically squeezed into the connection seat of the push rod.
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 exhaust 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 pneumatic door control system is according to the job order of motor and working procedure, time opening and close intake valve and exhaust valve, make inflammable mixture or air enter cylinder, and waste gas is discharged in cylinder, realize gas exchange process.The exhaust gear of motor generally is made up of timing gear, peach oblique crank Z, valve actuating push rod, pitman arm shaft (seat), rocking arm, exhaust valve, exhaust 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 exhaust valve and exhaust valve return spring, exhaust valve is opened, and this moment, cylinder was just finished the process of giving vent to anger, simultaneously when exhaust valve putter resets and drive the rocking arm return, exhaust valve resets under the return spring effect, exhaust valve closing.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 exhaust valve rocker arm 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 exhaust valve rocker arm spare, and main technical schemes is as follows:
A kind of exhaust valve rocker arm spare mainly comprises rocking arm mobile jib, shaft seat, 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.Shaft seat is arranged on the bottom of rocking arm mobile jib, and shaft seat forms two convex shoulders in the bottom of rocking arm mobile jib, be provided with rotary shaft hole in the shaft seat, and two end axle bed inner headed faces of rotary shaft hole are provided with the port slope angle; bar is located at one side of rocking arm mobile jib before the rocking arm, and the lower head of bar is provided with wear-resisting contact before rocking arm.
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 exhaust valve rocker arm 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 exhaust valve switch motion, 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 the exhaust valve putter connection part being added greasing substance.

(5) embodiment
As shown in drawings, a kind of exhaust valve rocker arm spare described in the utility model mainly comprises rocking arm mobile jib 1, shaft seat 2, rotary shaft hole 3, the preceding bar 5 of rocking arm, wear-resisting contact 6, push rod connecting base 7, push rod connecting screw hole 8, oil hole 9, interior lubricant oil pore 10, identified surface 11.Shaft seat 2 is arranged on the bottom of rocking arm mobile jib 1, and shaft seat 2 forms two convex shoulders in the bottom of rocking arm mobile jib 1, be provided with rotary shaft hole 3 in the shaft seat 2, and two end axle bed inner headed faces of rotary shaft hole 3 are provided with port slope angle 4; bar 5 is located at one side of rocking arm mobile jib 1 before the rocking arm, and the lower head of bar 5 is provided with wear-resisting contact 6 before rocking arm.
The another side of described rocking arm mobile jib 1 is provided with push rod connecting base 7, is provided with push rod connecting screw hole 8 in push rod connecting base 7.
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 9, and the other end of oil hole 9 is in rotary shaft hole 3.Simultaneously, for making things convenient for valve actuating push rod lubricating in push rod connecting base 7, the utility model has specially designed an interior lubricant oil pore 10 between rotary shaft hole 3 and push rod connecting screw hole 8, rotary shaft hole 3 interior unnecessary lubricant oil are automatically pressed in the push rod connecting base 7.
