Abstract
The utility model belongs to the technical field of the internal combustion engine, in particular to a pair piston type internal combustion engine. The utility model is composed of a casing body, a cylinder, an air supply assembly which is arranged on the outside of the cylinder, two pistons which are correspondingly arranged in the cylinder, the crank shafts A1, A2 which are matched with the pistons through a piston connecting rod, and a synchronizing transmission mechanism. The synchronizing transmission mechanism is composed of two cranks B1, B2 which are symmetrically arranged on the lower ends of the crank shafts A1, A2, and a transverse connecting rod. The both ends of the transverse connecting rod are respectively in running fit with the lower parts of the two cranks B1, B2. The upper ends of the crank shafts A1, A2 respectively are the output ends, or any end of the crank shafts A1, A2 is the output end. The utility model has simple and reasonable structure, low cost and good technological efficiency.
Description
Technical field
The utility model belongs to technical field of internal combustion engines, particularly a kind of pair-piston type internal-combustion engine.
Background technique
The patent No. is to disclose a kind of pair-piston type internal-combustion engine in 02267253.2 the utility model patent, the main cylinder double stopper type structure that adopts, drive behind the hyperbolic axle driven gear case synchronously by piston rod respectively by double-piston, drive the transmission shaft work done by power output wheel again after forming with joint efforts, in addition, also occurred some in the domestic and foreign literature and added turbine at the hyperbolic between centers, the synchronous drive mechanism of different structure designs such as scroll bar or the connection of employing belt, though above-mentioned prior art is in varying degrees at a cylinder one piston type internal-combustion engine that generally uses at present, efficient increases, vibration reduces, oil consumption reduces, but also exists complex structure simultaneously, the cost height, manufacturability is poor, deficiencies such as operational reliability and durability are low.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of pair-piston type internal-combustion engine to overcome the deficiencies in the prior art.
The technological scheme that its technical problem that solves the utility model adopts is:
This pair-piston type internal-combustion engine is by housing 5 and place cylinder 4 in the housing 5, distribution assembly 3, bent axle A1, A2, synchronous drive mechanism is formed, distribution assembly 3 is located at the cylinder outside, cylinder 4 is the pair-piston type structure, cylinder 4 bilateral symmetry are provided with bent axle A1, A2, bent axle A1, A2 connects by piston rod 1 and piston 2, synchronous drive mechanism is located at bent axle A1, the A2 bottom, wherein, described synchronous drive mechanism is by being symmetricly set on bent axle A1, the crank throw B1 of A2 lower end, B2 and transverse link 6 are formed, crank throw B1, the bending direction of B2 is consistent, transverse link 6 two ends respectively with crank throw B1, the B2 bottom is rotatably assorted, bent axle A1, the upper end of A2 is respectively output terminal or bent axle A1, any end of A2 is an output terminal.
Described crank throw B1, B2 upper end is one-body molded with bent axle A1, A2 lower end.
Described bent axle A1, A2 form by bearing with housing 5 internal surfaces respectively and are rotatably assorted.
The beneficial effects of the utility model are: this pair-piston type internal-combustion engine has simple and reasonable, advantage such as cost is low, good manufacturability, operational reliability height and durability are good, and comparing with existing internal-combustion engine significantly to promote the complete machine performance.
