Abstract
The utility model relates to engine art, especially a kind of lever balanced engine.Comprising: cylinder body, piston, first connecting rod, lever, second connecting rod and crankshaft, the piston is slidably connected with cylinder body, and the first connecting rod first end is hinged with piston, and the first end of second end and lever is hinged；The fulcrum of the lever is hinged with cylinder body, and the second end of the lever and the first end of second connecting rod are hinged, and the second end of the second connecting rod and the connecting rod neck of crankshaft are rotatablely connected, and the trunnion and cylinder body of the crankshaft are rotatablely connected.It is under equal conditions good by the setting balance of balance mechanism by the exportable bigger torque of lever, shockproof.
Description
Technical field
The utility model relates to engine art, especially a kind of lever balanced engine.
Background technique
For existing engine due to the setting of no balanced structure, shock conditions are serious, and the torque for tending to output is smaller.
Utility model content
The utility model aims to solve the problem that the above problem, provides a kind of lever balanced engine, it under equal conditions,
By the exportable bigger torque of lever, by the setting of balance mechanism, balance is good, shockproof, the technical solution used
It is as follows:
A kind of lever balanced engine characterized by comprising cylinder body, piston, first connecting rod, lever, second connecting rod
And crankshaft, the piston are slidably connected with cylinder body, and the first connecting rod first end is hinged with piston, and the of second end and lever
One end is hinged；The fulcrum of the lever is hinged with cylinder body, and the second end of the lever is mutually cut with scissors with the first end of second connecting rod
It connects, the second end of the second connecting rod and the connecting rod neck of crankshaft are rotatablely connected, and the trunnion and cylinder body of the crankshaft are rotatablely connected.
On that basis of the above technical scheme, the piston and first connecting rod are two, are symmetrically disposed on first connecting rod
The two sides of one end.
On that basis of the above technical scheme, two-piston is in same horizontal line.
On that basis of the above technical scheme, the distance of the fulcrum of the lever to lever first end is a, the branch of the lever
The distance of point to lever second end is that the ratio of b, a and b are 2:1.
The utility model has the advantages that under equal conditions, by the exportable bigger torque of lever, passes through balance
The setting of mechanism, balance is good, shockproof.

It cannot be understood as indicating or implying relative importance.
As depicted in figs. 1 and 2, a kind of lever balanced engine characterized by comprising cylinder body (not shown),
Piston 1, first connecting rod 2, lever 3, second connecting rod 4 and crankshaft 5, the piston 1 are slidably connected with cylinder body, the first connecting rod 2
First end is hinged with piston 1, and second end and the first end of lever 3 are hinged；The fulcrum 3a of the lever 3 is mutually cut with scissors with cylinder body
It connects, the second end of the lever 3 and the first end of second connecting rod 4 are hinged, second end and the crankshaft 5 of the second connecting rod 4
Connecting rod neck rotation connection, the trunnion and cylinder body of the crankshaft 5 are rotatablely connected.
Preferably, the piston 1 and first connecting rod 2 are two, are symmetrically disposed on the two sides of 2 first end of first connecting rod.
Preferably, two-piston 1 is in same horizontal line.By the setting of this balance mechanism, the engine balance is good,
It is shockproof.
Further, the distance of the fulcrum 3a of the lever 3 to 3 first end of lever is a, the fulcrum 3a of the lever 3 to thick stick
The distance of 3 second end of bar is that the ratio of b, a and b are 2:1.
The utility model is illustrated by way of example above, but the utility model is not limited to above-mentioned specific implementation
Example, all ranges that the requires of the utility model protection is belonged to based on any changes or modifications that the utility model is done.
