(54) ШАТУН ДЛЯ ДВИГАТЕЛЯ ВНУТРЕННЕГО (54) Crank for engine internal

1one

Изобретение относитс  к двигателестроению и касаетс  шатунов дл  двигателей внутреннего сгорани .FIELD OF THE INVENTION The invention relates to engine-building and relates to connecting rods for internal combustion engines.

Известны шатуны, содержащее верхнюю и нижнюю головки и расположенные между ними симметрично относительно продольной оси шатуна, по меньшей мере, два упругих элемента, армированные жестким стержнем 1.Known connecting rods containing the upper and lower heads and located between them symmetrically relative to the longitudinal axis of the connecting rod, at least two elastic elements, reinforced with a rigid rod 1.

Недостатком такого шатуна  вл етс  его недостаточна  надежность, обусловленна  возникновением повышенных изгибающих напр жений упругих элементов в момент действи  максимальных нагрузок.The disadvantage of such a connecting rod is its lack of reliability, due to the occurrence of increased bending stresses of elastic elements at the time of maximum loads.

Цель изобретени  - повыщение надежности путем ограничени  осевого перемещени  верхней головки шатуна.The purpose of the invention is to increase reliability by limiting the axial movement of the upper connecting rod head.

Цель достигаетс  тем, что в предложенном шатуне стержень размещен между упругими элементами вдоль оси шатуна, причем один торец стержн  закреплен в нижней головке, а другой снабжен опорной площадкой , расположенной в плоскости, перпендикул рной оси шатуна и установлен в верхней головке с зазором дл  упора в нее при достижении максимальной нагрузки. СГОРАНИЯThe goal is achieved by the fact that in the proposed rod the rod is placed between elastic elements along the axis of the rod, with one end of the rod fixed in the lower head and the other provided with a support platform located in a plane perpendicular to the axis of the rod and mounted in the upper head with a clearance for abutment her when the maximum load is reached. Combustion

На чертеже схематически изображен предложенный шатун дл  двигател  внутреннего сгорани .The drawing schematically shows the proposed connecting rod for an internal combustion engine.

Шатун дл  двигател  внутреннего сгорани  содержит верхнюю и нижнюю голов , ки 1 и 2, соединенные двум  упругими элементами 3 и 4, армированные жестким стержнем 5, и снабжен опорной площадкой 6.The connecting rod for the internal combustion engine contains upper and lower heads, ki 1 and 2, connected by two elastic elements 3 and 4, reinforced by a rigid rod 5, and provided with a support pad 6.

При работе двигател  на частичных нагрузках , упругие элементы 3 и 4 шатуна воспринимают продольное сжимающее усиto лие и за счет своей жесткости не изгибаютс .When the engine is operating at partial loads, the elastic elements 3 and 4 of the connecting rod perceive longitudinal compressive forces and, due to their rigidity, do not bend.

С увеличением нагрузки на двигатель до максимальной, упругие элементы изгибаютс  и жесткий стержень 5, закрепленный в нижней головке вдоль оси шатуна своим 5 торцом упираетс  в опорную площадку 6, расположенную в плоскости, перпендикул рной оси щатуна, что приводит к уменьшению его длины, степени сжати  в двигателе и давлени  сгорани .With an increase in the load on the engine to the maximum, the elastic elements bend and the rigid rod 5 fixed in the lower head along the axis of the connecting rod abuts with its 5 end to the supporting platform 6 located in a plane perpendicular to the axis of the connecting rod, which leads to a decrease in its length and degree of compression in the engine and the pressure of combustion.
