Description

A kind of piston reciprocating tank engine

Technical field

The invention belongs to field of internal combustion engine, and in particular to the piston reciprocating engine that a kind of tank uses.

Background technology

The dynamic power machine that existing tank uses, the overwhelming majority is using V-type engine, but V-type engine is relative to L The advantages of h type engine h, engine volume length is short when engine cylinder number is increased is easy to arrangement outer, not without other, and have with Under it is in the majority serious the defects of and weak point：It is complicated, involve great expense, maintenance and repair difficulty it is costly；Engine stabilizer Property is poor, especially V10 h type engine hs, need to put into great effort and funds overcome；The low speed torque that engine exports in itself is small, difficult To meet the demand of the low speed large torque of tank working environment, cause gearbox designs complexity cost high；Or increase piston length And increase the volume of engine.

The content of the invention

The defects of in order to overcome V-type engine that existing tank uses (lower referred to as " tank engine ") and weak point, The present invention discloses a kind of tank engine of structure novel, and technical characteristics are as follows：

A kind of piston reciprocating tank engine, it is characterised in that：It is vertical parallel in parallel for one with the cylinder of L-type engine two or so Multiple rows of twin-tub of row, " tank engine " V-type multiple rows of twin-tub in parallel is substituted, is allowed to form entire engine.

The engine power output system, by left bent axle (1), right bent axle (3), power and rotating speed output shaft (lower abbreviation " output shaft ") (2), left crankshaft toothed wheel (4), right crankshaft toothed wheel (6), output shaft gear (5) form；Output shaft (2) is arranged on a left side Centre between right two bent axles (1,3), output shaft gear (5) is driven gear, and left and right crankshaft toothed wheel (4,6) is all driving tooth Wheel, and engage to form gear train with output shaft gear (5) respectively.

The operating of multiple rows of twin-tub in parallel is without directly connection；The engine formed by the connection of the gear train gear Organic whole moves, and replacement " contrast engine " is respectively arranged or so two cylinder rods are connected in same bent axle and each formed on crank-pin Engine organic whole motion.

Output shaft (2) is one whole cylindrical d-axis, is substituted with the power and rotating speed of output shaft (2) output engine existing " tank engine " uses the power and rotating speed of bent axle output engine.

Left and right bent axle (1,3) synchronous axial system and in opposite direction, its rated engine speed is identical and the mark of equivalent " tank engine " Determine rotating speed, the rotating speed of output shaft (2) during two bent axle rated engine speeds, be output shaft (2) rated engine speed, namely inventive engine The rated engine speed outwardly exported.

The bent axle of left and right two and output shaft gear couple with left and right bent axle and output shaft respectively is integral structure；Left and right two is bent Shaft gear (4,6) reference diameter is identical, and the distance in its distance of center circle output shaft gear (5) center of circle is identical, and two gear synchronous rotate It is and in opposite direction；The demarcation that the rotating speed of crankshaft toothed wheel during the bent axle rated engine speed of left and right or so is referred to as to left and right crankshaft toothed wheel turns Speed, the demarcation of the rotating speed, referred to as output shaft gear (5) of output shaft gear (5) during the crankshaft toothed wheel of left and right two (4,6) rated engine speed Rotating speed, namely the rated engine speed of output shaft (2).

Left and right bent axle rated engine speed is identical, and for certain certain value, this rotating speed etc. compared with tank engine rated engine speed, it is defeated The rated engine speed that the rated engine speed of shaft designs for inventive engine.

If crankshaft toothed wheel reference diameter is D₁, bent axle rated engine speed is h₁；Output shaft gear reference diameter is D₂, it is defeated The rated engine speed of shaft is h₂, it is known that：h₁The rated engine speed of equivalent " contrast engine " and be certain value；h₂Make for design requirement The numerical value gone out, this numerical value can neatly be made according to design requirement.

If set h₂∶h₁=1: 3, by formula D₁∶D₂=h₂∶h₁, D can be obtained₁∶D₂=h₂∶h₁=₁∶3；That is output shaft rated engine speed It is 1: 3 with the ratio between bent axle rated engine speed, thus the ratio between crankshaft toothed wheel reference diameter and output shaft gear reference diameter are 1: 3；Then, as long as the h of Known designs₁And h₂Numerical value, it is possible to be made in the h of design₁And h₂The gear train to be worked under parameter, After loading onto the gear train, engine just according to the requirement of design, exports required rated engine speed.The present invention temporarily sets h₂∶h₁=1: 3, tool Body numerical value is made by specific design requirement.

Shown from the above mentioned with reference to Fig. 2 or Fig. 3, crankshaft toothed wheel reference diameter and output shaft gear point in adjustment gear group Spend the ratio between circular diameter, it is possible to the rated engine speed that regulation output shaft outwardly exports.

The gear train can be arranged on before engine, can also be arranged on behind engine.

Good effect

Due to existing " tank engine " V-type is changed into the vertical parallel twin-tub in parallel with the twin-tub of parallel connection, and use The connection of the one gear train gear, substitute " contrast engine " and often arrange twin-tub in parallel to be connected in same bent axle respectively with connecting rod each From the connecting mode on crank-pin, engine has that L-type engine cylinder-body and crankshaft structure are simple, manufacturing cost is low, stability Height, thermal efficiency height, smooth running, low speed torque is good, the advantages of being easy to assemble and repairing；There is V-type engine increase hair simultaneously Fuselage is short during engine cylinder number, the advantages of being easy to arrange.

Overcome that existing " tank engine " is complicated, involve great expense, to be unfavorable for M R, stability poor, Especially V10 h type engine hs, great effort need to be put into and the defects of expense overcomes its stability difference.

The cylinder Parallel Symmetric of left and right two, two bent axles and its pinion rotation speed are identical, in opposite direction in power drive system, tool There is the function of a pair of very outstanding balance shafts, make the stationary performance that engine operates reciprocal better than existing all types of piston internal combustions Engine.

Engine bottom is wide, has anti-inclination and the function of jolting, it installs the space taken, in addition to wider except bottom, with V It is essentially identical that h type engine h takes installing space.

It can change the mark of output shaft due to changing the ratio between crankshaft toothed wheel reference diameter and output shaft gear reference diameter Determine rotating speed, can easily meet the engine calibration rotating speed of design requirement, adapt to tank to the low rated engine speed of engine It is required that.

The rated engine speed of output shaft is reduced to the 1/3 of " contrast engine " rated engine speed by the present invention, then engine is low Fast torque is increased to 3 times of existing " tank engine " low speed torque, substantially increases low engine speed service behaviour.

Prior art and production equipment can be fully utilized, time and expense that research and development and manufacture consume are reduced, shorter Time in formed production scale, play significant economic effect and social benefit, China's combustion engine manufacture industry is moved towards generation Boundary's advanced level.
