Description
Technical field
The present invention relates to stroke piston combustion engine technical field.
Background technology
Bringing back to life piston type internal-combustion engine is the complex machines that the thermal energy that a kind of burning fuel produces becomes kinetic energy.Back and forth
The working chamber of internal-combustion piston engine is referred to as cylinder, and cylinder surfaces is cylindrical.In cylinder reciprocating
Piston is connected with bent axle by connecting rod, constitutes toggle.Therefore, in cylinder, reciprocal fortune is made when piston
Time dynamic, connecting rod just promotes bent axle to rotate, or on the contrary.Meanwhile, the volume of working chamber is also constantly by minimum
Changing to maximum, then changed to minimum by maximum, so circulation is endlessly.The top cylinder head of cylinder is closed.At gas
Equipped with inlet valve and exhaust valve on cylinder cap, realize inflating and to cylinder in cylinder by the opening and closing of inlet and outlet door
Outer aerofluxus.The opening and closing of inlet and outlet door is by camshaft control.
Camshaft is driven by bent axle, the kind of drive of bent axle to camshaft mainly have three kinds, i.e. gear transmission chain
Bar transmission and cog belt transmission, the typically transmission from bent axle to camshaft have only to a pair timing gears, if desired
Breast wheel to be installed additional.Chain drive can meet due to the distant distribution starting motivation of bent axle and camshaft
Transmission requirement, but structure is more complicated, adjusts inconvenience, and its serviceability depends on the system with chain to a great extent
Make quality；Synchronous cog belt is the most wide variety of a kind of kind of drive, but can be used to replace chain to pass
Dynamic, use profile of tooth bar transmission, noise can be reduced, reduce architecture quality.Drive mechanism excellent be reduce noise,
Improve the emphasis of output.
Bringing back to life the piston type internal-combustion engine electromotor as automobile, its performance quality directly influences automotive performance, starts
The type of machine is a lot, and configurations, to adapt to the needs of different automobile types.Fuel is used to divide by electromotor, can
It is divided into the classification such as petrol engine and Diesel engine.By engine cylinder arrangement mode divide, be divided into array,
V-type, pancake engine etc..
Engine cylinder below 6 cylinders mostly is single straight column mode, and minority 6 Cylinder engine also has straight column mode.
In-line engine simple in construction, low price, shortcoming is that electromotor height is higher, and length is longer；V-type is sent out
Motivation operating is relatively more steady, and vibration and noise is less, the most relatively low, and length is shorter, can reserve phase for driving cabin
To big space, shortcoming is to use two cylinder covers, and structure is relative complex, and price is the most expensive；Level pair
Putting electromotor to be typically mounted on the centrage of car load, piston is evenly distributed in bent axle both sides, in the horizontal direction
Side-to-side movement, the moment that both sides piston produces is cancelled out each other, and is substantially reduced the operating vibration of vehicle, and minimizing is made an uproar
Sound, engine speed is greatly improved, and oil consumption is relatively low, and make the whole height of electromotor reduce, length contracting
Short, but its technology requires the highest, and cooling system also requires that very strict, and manufacturing cost is than V-type engine more
High.
Develop body to take up space in little, structure relative simplicity low cost and high novel of the little output of noise
Burn engine, the target always pursued in the industry.
Summary of the invention
The present invention need to solve the technical problem that and there is provided that a kind of structure is relatively easy, low cost of manufacture, volume are little
The automobile engine that energy consumption is low.
For solving above-mentioned technical problem, the technical scheme that the present invention realizes is:
A kind of automobile engine of design, includes engine body and the valve actuating mechanism being disposed on body.Body
Including cylinder, piston brace rod reciprocating in cylinder connects slide block, one and power output shaft
Having groove slideway on the rotor outer wall of engagement, described slide block is placed in groove slideway and makes piston brace rod and turn
Linkage is formed between son；Described valve actuating mechanism includes valve switch rotating shaft and the control inlet and outlet being disposed thereon
The valve switch cam of door trip, is passed by gear engagement system between valve switch rotating shaft and power output shaft
Dynamic, the power gear on power output shaft engages with the driven gear in valve switch rotating shaft, power gear and band
The gear ratio of moving gear is 1: 2.
As the improvement of such scheme, the groove slideway on rotor outer wall is with the SIN function shaped form in a cycle
State is distributed.Cylinder with two be a composition as listed in power output shaft both sides, often group two cylinders cylinder jacket be linked to be
Integrally, piston brace rod shares, and described slide block is fixed on the middle part of piston brace rod.
It is taper that power gear is arranged on the two ends of power output shaft, power gear and the driven gear engaged
Gear, the valve switch rotating shaft vertical distribution that power output shaft drives with driven gear, described valve switch is convex
Wheel is arranged on the two ends of valve switch rotating shaft, and valve switch cam can be with the gas being arranged on the top often organizing cylinder
Inlet and outlet door contact on cylinder cap so that inlet and outlet door opens or closes.
The present invention has following remarkable advantage compared to existing technology:
1, this automobile engine, the piston brace rod of cylinder is not connected with bent axle, and is by mean of slide block with outer
The rotor having groove slideway on wall connects so that the linear reciprocating motion of cylinder piston is transformed into rotor and moves
The rotary motion of power output shaft, this kind of drive, simple in construction, difficulty of processing is low, can reduce and be manufactured into
This.
2, this engine body with rotor, volume is little, it is easy to putting of engine location.Also can be
Drive cabin and reserve relatively large space.
3, by the rotational structure of piston brace rod rotor driven, connecting portion reduces, and reduces friction, has
Effect ground reduces energy consumption, improves the output of electromotor.
4, cylinder is symmetricly set on rotor and power output shaft both sides, completely designs journey, vibrates little, make an uproar
Sound is low.
