Abstract
The utility model discloses an engine piston link rod device, which comprises an engine cylinder body and a piston arranged a cylinder of the cylinder body, and double oil cylinders are also arranged in the cylinder body. Connecting rods are composed of an upper connecting rod and a lower connecting rod, a small piston arranged in a small oil cylinder of the double oil cylinders is connected with the upper connecting rod, and a large piston arranged in a large oil cylinder of the double oil cylinders is connected with the lower connecting rod. the upper connecting rod is connected with the pistons, and the lower connecting rod is connected with an engine crankshaft. The utility model has the advantages of reducing the impact force of the connecting rods on the crankshaft, enhancing the active force of the pistons on the crankshaft and reducing the oil consumption of an engine.
Description
Technical field:
The utility model relates to a kind of engine piston connecting rod device, belongs to technical field of engines.
Background technique:
At present, engine piston connecting rod device of the prior art, its connecting rod generally all is connected by an all-in-one-piece straight-bar with the two ends that piston is connected with bent axle, the connecting rod of this structure exists the impact force of bent axle big in use, make motor when work, produce bigger noise, and the connecting rod of this structure also reduces the active force of piston to bent axle easily, thereby causes the oil consumption of motor to increase.
Summary of the invention:
The purpose of this utility model is: provides a kind of and can reduce the impact force that bent axle is produced, thereby and can improve the engine piston connecting rod device of piston to the active force reduction engine consumption of bent axle, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises engine cylinder-body (1) and is contained in piston (2) in the cylinder of cylinder body (1), two oil cylinders (3) also are housed in cylinder body (1), and connecting rod is made up of last connecting rod (4) and lower link (5), on last connecting rod (4), be connected with the small piston (6) in the small oil tank that is contained in two oil cylinders (3), on lower link (5), be connected with the big piston (7) in the large tank that is contained in two oil cylinders (3), last connecting rod (4) is connected with piston (2), and lower link (5) is connected with the bent axle (8) of motor.
Owing to adopted technique scheme, the utility model compared with prior art can reduce connecting rod to impact force that bent axle produced and can improve piston reduces engine consumption to the active force of bent axle advantage thereby the utlity model has.When using the utility model, when piston promotes to go up connecting rod (4) downwards, last connecting rod (4) is pressed into the oil in its small oil tank in the large tank and by big piston (7) and lower link (5) by small piston (6) and promotes bent axle (8) motion, because the effect of the isobaric transfer principle of hydraulic pressure, make on the big piston (7) and be subjected to bigger active force, thereby make bent axle (8) be subjected to bigger power effect; In addition because the effect of hydraulic oil buffering has reduced the impact of connecting rod to bent axle.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
Embodiment:
Embodiment of the present utility model: during making in general engine cylinder-body (1) below of each piston/cylinder all adorn a two oil cylinder (3), and the connecting rod of routine is cut off, it is become go up connecting rod (4) and lower link (5), on last connecting rod (4), connect the small piston (6) in the small oil tank that is contained in two oil cylinders (3), on lower link (5), connect the big piston (7) in the large tank that is contained in two oil cylinders (3), to go up connecting rod (4) and be connected with piston (2), lower link (5) is connected with the bent axle (8) of motor.
Claims (1)
1, a kind of engine piston connecting rod device, it comprises engine cylinder-body (1) and is contained in piston (2) in the cylinder of cylinder body (1), it is characterized in that: two oil cylinders (3) also are housed in cylinder body (1), and connecting rod is made up of last connecting rod (4) and lower link (5), on last connecting rod (4), be connected with the small piston (6) in the small oil tank that is contained in two oil cylinders (3), on lower link (5), be connected with the big piston (7) in the large tank that is contained in two oil cylinders (3), last connecting rod (4) is connected with piston (2), and lower link (5) is connected with the bent axle (8) of motor.
