Description
Technical field
Engine drive mechanism, the linear reciprocating motion of piston can be converted to the rotation of bent axle by this mechanism.
Background technique
At present, the piston-engined driving mechanism overwhelming majority is the circular movement linear reciprocating motion of piston being directly converted to bent axle by connecting rod and bent axle in the world, thus drives wheel to advance or retreat, and forms of motion for once converts.The shortcoming of this technological scheme is that the sidewall of piston to cylinder itself produces huge pressure, thus increases the wearing and tearing of piston and cylinder, greatly reduces the working life of piston and cylinder.Traditional piston, connecting rod, crank mechanism also bring the difficulty of distribution engine, because each piston group must have a connecting rod to be connected with a connecting rod neck of bent axle, and piston group and connecting rod can only along the axial distribution of bent axle, therefore along with the increase of engine piston group, bent axle is just more and more longer.Bent axle is longer, and the easier bending deflection of bent axle, manufacture cost is higher.Because the piston stroke design of conventional engines designs directly related with the radius of gyration of bent axle, therefore this all brings many troubles to the design of engine piston group and bent shaft design.
(1) technical problem to be solved by this invention
The T-shaped connecting rod piston engine drive mechanism object of the present invention's design is to overcome above-mentioned deficiency, which eliminate piston basis in time doing linear reciprocating motion to the pressure of cylinder sidewall, improve the working life of piston and cylinder, reduce the manufacture cost of piston group.Piston-engined driving mechanism due to the present invention's design have employed two piston groups and acts on a T-shaped connecting rod simultaneously, this T-shaped connecting rod is only connected with a connecting rod neck of bent axle, be equivalent to two piston groups and only occupy a connecting rod neck, therefore, it is shorter that bent axle can design, and the volume ratio of driving mechanism on the direction of axis line that the piston engine of same cylinder number adopts the present invention to design adopts conventional drives volume in the direction in which to reduce half.Because the T-shaped connecting rod piston engine drive mechanism of the present invention's design adopts two piston groups to be symmetrically distributed in the both sides of T-shaped connecting rod, therefore, the spacing between engine piston group is larger, and heat radiation is better.Because the piston-engined driving mechanism of the present invention's design takes the swing linear reciprocating motion of piston being first converted to T-shaped connecting rod, the swing of T-shaped connecting rod is converted to the technological scheme of twice motion conversion of crank rotation again, therefore, the design of piston stroke and crank rotation radius is no longer directly related, can suitably strengthen under the constant condition of crank rotation radius according to actual conditions or reduce piston stroke, also under the constant condition of piston stroke, can suitably strengthen or reduce the radius of crank rotation, this is to engine piston group and bent shaft design band convenience.

(3) due to intermediate conversion body that T-shaped jointed gear unit of the present invention is piston linear reciprocating motion and crank rotation, there is buffer action, therefore, adopt the motor of T-shaped jointed gear unit of the present invention, the radius of gyration design of the design of its piston stroke and bent axle can have multiple different combination, makes the simpler variation of engine design.
(4) specific embodiment
Use the T-shaped connecting rod piston engine drive mechanism of the present invention's design can form the piston engine that two cylinder, four cylinders, six cylinders, eight cylinders etc. have even cylinder number, and the piston engine that single cylinder, three cylinders etc. have odd cylinders number can not be formed.The T-shaped connecting rod piston engine drive mechanism how using the present invention to design is described for two cylinder piston engines and four cylinder piston engines below, and other even cylinder piston engines can be analogized and obtain.
(1) two cylinder piston engine
Use the T-shaped connecting rod piston engine drive mechanism of the present invention's design can form two cylinder piston engines, concrete structure is as shown in Figure of description.When piston (3) moves downward, piston (3) lower gear rack (9) engages with T-shaped connecting rod (1) A end tooth (12), T-shaped connecting rod (1) is driven to swing to the right, T-shaped connecting rod (1) B end tooth (13) engages with the tooth bar (10) of piston (4) bottom, driven plunger (4) moves upward, now the connecting rod neck (8) of bent axle (2) is held in groove (14) at T-shaped connecting rod (1) C and is slided, and T-shaped connecting rod (1) driving crank (2) is rotated clockwise.When T-shaped connecting rod (1) swings to low order end, under the effect of newton law of inertia, bent axle (2) continues to rotate clockwise, the connecting rod neck (8) of bent axle (2) holds slide downward in groove (14) to drive T-shaped connecting rod (1) to start to swing left at T-shaped connecting rod (1) C, T-shaped connecting rod (1) B end tooth (13) driven plunger (4) moves downward, and T-shaped connecting rod (1) A end tooth (12) driven plunger (3) moves upward.Under two pistons replace acting and bent axle effect of inertia, motor just can go down in continuous running like this.
(2) four cylinder engine
Four cylinder engine can be combined by two above-mentioned two cylinder motors.Just being united two into one by the bent axle of original two Cylinder engines, it is just passable to become single axle.This bent axle has two connecting rod necks, and phase 180 degree, and the T-shaped connecting rod of two Cylinder engines above-mentioned with two is connected respectively, thus form four cylinder piston engines.The working procedure of each T-shaped connecting rod piston engine drive mechanism of this four cylinder engine is identical with the working procedure of above-mentioned two Cylinder engines, just no longer describes at this.
