Abstract
The utility model relates to a crankshaft-linkage lever mechanism. The utility model comprises a crankshaft, a linkage lever, and a balance weight. The utility model has the basic improved structure that the traditional opposite open type linkage lever is changed into an integral linkage lever; the linkage lever is provided with a big hole end; the longitudinal section of the big hole end is provided with a continuous sleeve barrel; the big hole end is directly sheathed on an axle neck; only one end of the crankshaft is provided with the balance weight. Compared with the traditional technique. The utility model has the advantages of simple structure, easy assembly, low cost, etc. Particularly, because the occupied space position is small, the utility model improves the condition for the design of an air compressor and even a main engine.
Description
The utility model relates to a kind of improved crankshaft-linking rod drive mechanism, particularly the automobile brake crankshaft ﹠ connecting of Piston Air Compressor.
The crankshaft ﹠ connecting of traditional automobile brake Piston Air Compressor all adopts the opposite opened crankshaft ﹠ connecting, its manufacturing process complexity, difficulty height, take up space big, the cost height, production has high input, and also difficulty of assembling.
The purpose of this utility model is to overcome the shortcoming of opposite opened linkage mechanism, propose a kind of simple in structure, the position that takes up space is little, the design proposal of the crankshaft ﹠ connecting of easy assembling.
The purpose of this utility model is achieved in that
A kind of crankshaft ﹠ connecting, it comprises bent axle, connecting rod, balancer weight, its basic improvements are, it makes traditional opposite opened connecting rod into monolithic linkage, described connecting rod is provided with a small bore end and a big nose end, described small bore end is connected with piston assembly, and the longitudinal section of described big nose end is a continuous sleeve, and big nose end directly is enclosed within on the axle journal.
Aforementioned link mechanism, between described big nose end internal diameter and the axle journal external diameter be the 2-4 level movingly.
Aforementioned link mechanism, described bent axle have only an end to be provided with a balancer weight.
Aforementioned link mechanism, described big nose end is added with an axle sleeve.
The utility model is compared with conventional art, because connecting rod shank, connecting rod cap are merged into an integral body, anterior-posterior balance is overlapped and is reduced to a balancer weight, therefore simplify the structure, make this connecting rod have assembling advantage easy, with low cost, particularly because the position that takes up space is little, thereby improved condition for the design of air compressor and even master motor.
Accompanying drawing 1 is a sectional view of the present utility model;
Accompanying drawing 2 is a kinematic sketch of the present utility model.
Below in conjunction with accompanying drawing the utility model is further described:
Parts in the utility model comprise bent axle, connecting rod 1, balancer weight 4 etc., and the wall thickness of its axle sleeve 5 is the 2-5 millimeter, and material can be selected 20 high tin aluminium, Babbitt, tin bronze etc. for use.
Linkage mechanism according to the utility model making, when the big nose end 2 of monolithic linkage 1 is fashionable from the end cover that bent axle does not have aequum, need take a series of connecting rod tilting action, the connecting rod cover can be filled to rod journal 3 places of bent axle, and realization axially locating, and have only an end to be provided with a balancer weight 4 in the two ends of bent axle, during work, connecting rod tip is made circular movement with rod journal in the plane perpendicular to crankshaft axis and mistake air compressor sleeve port center, connecting rod small bore end 6 is connected with piston assembly, piston is subjected to the restriction of cylinder sleeve and is reciprocating, the comparatively compound movement of the synthetic connecting rod of the circular movement at connecting rod two ends and to-and-fro motion, the body that movement locus requires to contain mechanism must have the space of satisfying the motion needs.Because this crankshaft ﹠ connecting has been cancelled the combined structure of connecting rod and lid, volume-diminished, thereby also just dwindled the needed spatial position of a mechanism kinematic, improved condition for the design of air compressor and even master motor.
