Abstract
The utility model discloses a valve rocker part, which belongs to the technical field of valve timing mechanisms of internal combustion engines, and solves the problems that a valve rocker of the conventional internal combustion engine only can control the starting and the closing of a valve in a same series of the valve rocker and is small in volumetric efficiency. The valve rocker part comprises a valve rocker, a valve rocker bushing and a push rod mounting hole, wherein a valve rocker head strut, a valve rocker head support and a valve rocker bridge are arranged below the valve rocker, and two ends of the valve rocker bridge are respectively provided with a valve mounting hole. When the valve rocker part is used, inlet valves or outlet valves are arranged at the valve mounting holes at the two ends of the valve rocker bridge. According to the valve rocker part, two valves in the same series are connected with the valve rocker bridge, the valve rocker bridge simultaneously moves along with the swinging of the valve rocker so as to simultaneously start and close the valves (connected on the valve rocker bridge) in the same series, so that the number of valves of the conventional engine can be increased from two in one cylinder to four in one cylinder, thereby improving the volumetric efficiency.
Description
Technical field
The utility model belongs to the I. C engine distribution mechanism technical field, and is particularly a kind of for realizing that four-valve air distribution mechanism is with the valve rocker apparatus on the small-bore diesel engine that satisfies state's IV and above emission regulation demands.
Background technique
In field of internal combustion engine, adopt the opening and closing of valve rocker control valve, traditional mode is the opening and closing through a valve of the same name of a valve rocker control.The subject matter that exists is to realize that single cylinder four air valve structures make the air inlet of every cylinder and exhaust sectional area little, and volumetric efficiency is little, can not satisfy state's IV and above emission regulation demands.
Summary of the invention
Can only control the opening and closing of a valve of the same name for solving a valve rocker that has internal-combustion engine now, the air inlet of every cylinder and exhaust sectional area are little, the problem that volumetric efficiency is little, and the utility model provides a kind of arm sub-assembly of valve, and its technological scheme is following:
A kind of arm sub-assembly of valve comprises valve rocker, under the valve rocker valve rocker bushing is arranged, and the rear end of valve rocker has the push rod mounting hole;
The front end below of said valve rocker is equipped with valve rocker head pillar; On the ballhead of valve rocker head pillar lower end valve rocker head bearing is installed; Valve rocker head bearing below is equipped with the valve rocker bridge, and respectively there is a valve mounting hole at valve rocker bridge two ends.
During use, on the valve mounting hole at valve rocker bridge two ends, be installed into valve or exhaust valve gets final product.
Novel two valves of the same name and the valve rocker bridging of this use connects; The valve rocker bridge is by valve rocker head component; The assembly parts that promptly is made up of valve rocker head pillar and valve rocker head bearing drives it and moves up and down; Valve rocker head component is connected with valve rocker, and swings with the swing of valve rocker, thereby the valve of the same name that will be connected on the valve rocker bridge opens or closes simultaneously.
The utility model beneficial effect is:
Can make the valve number of existing motor increase to four by two in every cylinder, the air inlet of every cylinder and exhaust sectional area increase, and volumetric efficiency increases; Simple in structure, cheap, easy to assembly.
Description of drawings
Schematic representation when Fig. 1 is used as the inlet valve rocker parts for the utility model;
Schematic representation when Fig. 2 is used as the exhaust valve rocker arm parts for the utility model.
Embodiment
Like Fig. 1 or arm sub-assembly of valve shown in Figure 2, comprise valve rocker 4, valve rocker has valve rocker bushing 54 times, and the rear end of valve rocker 4 has the push rod mounting hole;
The front end below of said valve rocker 4 is equipped with valve rocker head pillar 2; On the ballhead of valve rocker head pillar 2 lower ends valve rocker head bearing 3 is installed; Valve rocker head bearing 3 belows are equipped with valve rocker bridge 1, and respectively there is a valve mounting hole at valve rocker bridge 1 two ends.
The working procedure of above-mentioned parts is following:
The swing of inlet and outlet door Rocker arm 4; Valve rocker head pillar 2 moves up and down with valve rocker head bearing 3 thereupon; The motion of valve rocker head pillar 2 and valve rocker head bearing 3 drives valve rocker bridge 1 and moves up and down; Valve rocker bridge 1 is connected with two intake valves or two exhaust valves, through moving up and down of valve rocker bridge 1, opens when realizing two inlet and outlet doors or closes.
