Abstract

The utility model relates to a straight shaft angle internal-combustion engine without a crankshaft, and is composed of a slide block and a circular disc. A traditional crankshaft is canceled. The utility model is the improvement of driving mode, and has the advantages of reasonable design, simple structure, easy fabrication, light weight, low cost, etc. The utility model is also characterized in that a crankshaft, a balancing device and a return flywheel are omitted, so transmission efficiency is enhanced.

Description

Straight shaft angle change piston reciprocating IC engine

The utility model relates to internal-combustion piston engine, does not particularly have bent axle d-axis angle and becomes internal-combustion piston engine.

As everyone knows, traditional internal-combustion engine is the transmission that comes realizable force with the bent axle circular movement, but the crankshaft structure complexity, volume is big, processing and fabricating is difficult, and it is that the bent axle circular movement produces centrifugal force and vibrations that major defect shows as one, must be equipped with Equilibrator; The 2nd, the bent axle circular movement makes piston produce the dead point, must be equipped with backhaul guiding flywheel, has both increased weight, has consumed energy again, has hindered the raising of the efficiency of internal combustion engine.

The purpose of this utility model provides a kind of no bent axle, with disk, slide block, link rod, piston be one have internal-combustion engine of 90 ° of piston motions.

The purpose of this utility model is realized by following scheme: it comprises piston 1, link rod 2, slide block 3 and disk 5 etc., it is characterized in that disk 5 surfaces have cross recess, is separated with slide block 3,4 between groove is interior, and slide block 3,4 is separately fixed at the middle part and the end of link rod 2.

The working principle that the d-axis angle becomes internal-combustion piston engine is, when piston reciprocates, is not reciprocating by bent axle, does angular transformation, disc rotated but promote slide block with the piston link rod.

The utility model is reasonable in design, simple in structure, making is easy, in light weight, cost is low, is the once improvement on the kind of drive, and major advantage is: a, saved bent axle; B, saved the moving equilibrium device; C, save the backhaul flywheel, alleviated proportion, improved transmission efficiency.

The utility model accompanying drawing 1 is a structural representation, Fig. 2 is the disc structure schematic representation, Fig. 3 is its A-A sectional view, motion view when Fig. 4 is piston top dead center, motion view when Fig. 5 is descent of piston, motion view when Fig. 6 is the piston lower dead center, motion view when Fig. 7 is the piston lower dead center.

Wherein piston 1, link rod 2, slide block 3,4, disk 5.

Claims

1, a kind of d-axis angle change internal-combustion piston engine comprises piston 1, link rod 2, slide block 3 and disk 5 etc., it is characterized in that disk 5 surfaces have cross recess, is separated with slide block 3,4 between groove is interior, and slide block 3,4 is separately fixed at the middle part and the end of link rod 2.
