Abstract
The utility model discloses an improved crankshaft connecting rod mechanism for an internal-combustion engine. The improvement is that two connecting rods and two parallel crankshafts connected with the connecting rods are arranged on a piston pin. The improved crankshaft connecting rod mechanism for an internal-combustion engine overcomes the side force generated by a traditional crankshaft connecting rod mechanism fundamentally eliminates wattless friction, relatively improves transmission efficiency, extends the service life of the internal-combustion engine, and reduces energy consumption.
Description
The utility model is a kind of improved internal-combustion engines crank-connecting rod mechanism.
The piston of existing internal-combustion piston engine will be subjected to a kind of effect of lateral force in the to-and-fro motion process, piston is pressed on the cylinder wall and causes idle friction, its result has consumed useful work on the one hand, and one side easily makes the cylinder wall wearing and tearing and causes gas leakage, reduces the efficient of internal-combustion engine.
The purpose of this utility model is a kind of internal-combustion engines crank-connecting rod mechanism that can eliminate the piston lateral force of design.
The purpose of the utility model is to realize like this; Make traditional single set of bell cranks linkage mechanism into arranged side by side two groups, wherein single head connecting rod place between the jaw of a forked type connecting rod and by wrist pin with two rod hinge connections on piston, the other end of two connecting rods is single head and is hinged with two cranks.
The internal-combustion engine that adopts this design and make, its piston no longer acts in movement process lateral force, so have the transmission efficiency height, improve internal-combustion engine working life, reduce oil consumption, reduce the characteristics of polluting and reducing internal-combustion engine manufacturing technique requirent and cost, its disadvantage has been to increase the mechanism complexity of internal-combustion engine.
Concrete structure of the present utility model is provided by following examples and accompanying drawing.
Fig. 1 is the sectional view according to the mechanism that the utility model proposes; Fig. 2 is the assembling diagrammatic sketch of this mechanism.
Bottom is described with reference to the accompanying drawings the specific structural details of this mechanism.
There is a piston in this mechanism, have by two hinged connecting rods that length dimension is identical of wrist pin down at it, the articulated joint of one of them connecting rod is a fork-shaped, another connecting rod then is a single head, and place in the middle of the knuckle joint, the following articulated joint of two connecting rods is hinged with the offset crank of two same sizes respectively, and two cranks utilize the right common internal combustion engine output shaft that drives of gear one the first from left.As shown in Figure 1 and Figure 2, wherein:
1-cylinder 2-piston 3-wrist pin 4-single head connecting rod
5-crank 6-crank 7-forked link
Adopted the internal-combustion engine of this connecting rod can realize that the height between cylinder and piston is airtight, offset crank linkage mechanism itself can make reciprocating motion of the pistons speed differ, and can further improve the efficient of internal-combustion engine by reasonable control.Owing to no longer include lateral force on the piston, so there is not wear problems in the life-span of cylinder and increases substantially.
