Abstract
The utility model discloses a parallel type connecting rod applied to a V-type engine. The parallel type connecting rod comprises a first connecting rod body and a second connecting rod body. The first connecting rod body and the second connecting rod body are both oblique incision connecting rods and are both connected to a same crank throw crank pin of a crankshaft. When the included angle between a plane determined by the center line of the crank pin of the crankshaft and the rotary center line of the crankshaft and the center line of a first air cylinder and the included angle between the plane determined by the center line of the crank pin of the crankshaft and the rotary center line of the crankshaft and the center line of a second air cylinder are the same, the included angle between a connecting line of the centers of two installation holes of a connecting rod bolt of a large head cover of the second connecting rod body and the plane determined by the center line of the crank pin of the crankshaft and the rotary center line of the crankshaft ranges from 65 degrees to 88 degrees, and the included angle between a connecting line of the centers of two installation holes of a connecting rod bolt of a large head cover of the first connecting rod body and the connecting line of the centers of the two installation holes of the connecting rod bolt of the large head cover of the second connecting rod body ranges from 22.5 degrees to 30.5 degrees. The special angle is formed by the two connecting rod bodies, so that in the working process, a crank connecting link structure is small in operation envelope line and flexible in operation, abrasions are reduced, and the output power of the engine is accordingly improved.
Description
Technical field
The utility model belongs to engine art, relates in particular to a kind of engine components, refers in particular to a kind of abreast-type connecting rod that is applied to V-type engine.
Background technique
Connecting rod is petrolic vitals, and it is connected with the crank pin of bent axle.Connecting rod divides first connecting rod and second connecting rod, and when connecting rod work, connecting rod small end end is with piston reciprocates, and connnecting rod big end end rotates around crankshaft center line with crank pin, and the shaft between connecting rod CONCENTRIC REDUCER is done complicated oscillating motion.In prior art, in the time that V-type twin-tub machine runs to lower dead center (crank of bent axle runs to vertically upward), the first and second connecting rods can not form a special angle, cause the working efficiency of motor not ideal.
Model utility content
Technical problem to be solved in the utility model is: a kind of abreast-type connecting rod that is applied to V-type engine is provided, by changing between two connecting rods the angle when the lower dead center, thereby make its running envelope enough little, and then reduction length of connecting rod, quality and minimizing crankcase volume, two connecting rods are effectively coordinated, improve the working efficiency of motor.
The technical solution of the utility model is as follows:
A kind of abreast-type connecting rod that is applied to V-type engine, comprise first connecting rod and second connecting rod, described first connecting rod and described second connecting rod are angular cut connecting rod, all be connected on the same crank throw crank pin of bent axle, it is characterized in that: the definite plane of described crankshaft crank pin center and crank up center line is respectively with first, when the angle of the second cylinder center is identical, between the definite plane of the hole line of centres of described second connecting rod major part cover connecting rod bolt two mounting holes and described crankshaft crank pin center and crank up center line, angle is between 65 ° to 88 °, angle between the hole line of centres of the hole line of centres of described first connecting rod major part cover connecting rod bolt two mounting holes and second connecting rod major part cover connecting rod bolt two mounting holes is between 22.5 ° to 30.5 °.
The above-mentioned abreast-type connecting rod that is applied to V-type engine, when the described crankshaft crank pin center plane definite with crank up center line is identical with the angle of first, second cylinder center respectively, between the definite plane of the hole line of centres of described second connecting rod major part cover connecting rod bolt two mounting holes and described crankshaft crank pin center and crank up center line, angle is 76.5 °.
The above-mentioned abreast-type connecting rod that is applied to V-type engine, when the described crankshaft crank pin center plane definite with crank up center line is identical with the angle of first, second cylinder center respectively, the angle between the hole line of centres of described first connecting rod major part cover connecting rod bolt two mounting holes and the hole line of centres of second connecting rod major part cover connecting rod bolt two mounting holes is 26.5 °.
The beneficial effects of the utility model are: do not changing under the prerequisite of bar linkage structure and crankshaft drive structure, when the described crankshaft crank pin center plane definite with crank up center line is identical with the angle of first, second cylinder center respectively, be that V-type twin-tub machine is while running to lower dead center (crank of bent axle runs to vertically upward), two connecting rods form special angle, make brace and connecting rod framework running envelope in the course of the work enough little, turn round more flexible, transmission wearing and tearing reduce, thereby make the output power of motor obtain the lifting of certain amplitude.

Embodiment
In this article, these embodiments of the present utility model can be represented with term " model utility " individually or always, this is only used to conveniently, and if in fact disclose the model utility that exceedes, not that the scope that will automatically limit this application is any single model utility or model utility design.
Embodiment 1
As shown in Figure 1, a kind of abreast-type connecting rod that is applied to V-type engine described in the utility model, be applied to put-put, especially a kind of V-type double-cylinder gasoline engine, comprise first connecting rod 1 and second connecting rod 2, described first connecting rod 1 and described second connecting rod 2 are angular cut connecting rod, are all connected on the same crankshaft pin of bent axle 3, and described first connecting rod 1 and described second connecting rod 2 have included a large skull.
Referring to Fig. 2 and Fig. 3, in the time that crankshaft crank pin center 5 plane definite with crank up center line 6 is identical with the angle of first, second cylinder center 7,8 respectively, between the definite plane of the hole line of centres of second connecting rod 2 major part cover connecting rod bolt two mounting holes 4 and described crankshaft crank pin center 5 and crank up center line 6, angle is between 65 ° to 88 °, preferably, this angle is 76.5 °.
Angle between the hole line of centres of the hole line of centres of described first connecting rod 1 major part cover connecting rod bolt two mounting holes and second connecting rod 2 major part cover connecting rod bolt two mounting holes 4 is between 22.5 ° to 30.5 °, and preferably, this angle is 26.5 °.
