Description

ОПИСАНИЕ DESCRIPTION

ШАТУН С ПРУЖИННЫМ АМОРТИЗАТОРОМ CONNECTING ROD WITH SPRING SHOCK ABSORBER

Известны механизмы использования пружинного амортизатора в качестве аккумулятора энергии. В полезных моделях иа 119025 и, и иа 125509, тело шатуна изготовлено как пружинный амортизатор, с той разницей, что во второй модели роль пружины играет пружина. В обоих случаях амортизатор аккумулирует кинетическую энергию удара, приходится на коленвал и его подшипники на начальной стадии движения поршня, и отдает накопленную энергию, когда сила упругости сжатого пружины становится больше силы сопротивления, тем самым увеличивая мощность двигателя. Known mechanisms for using a spring shock absorber as an energy accumulator. In utility models ia 119025 and ia 125509, the connecting rod body is made as a spring shock absorber, with the difference that in the second model the role of the spring is played by the spring. In both cases, the shock absorber accumulates the kinetic energy of the impact, falls on the crankshaft and its bearings at the initial stage of the piston movement, and gives up the accumulated energy when the elastic force of the compressed spring becomes greater than the resistance force, thereby increasing the engine power.

Но обе модели имеют недостатки. Так, недостатком модели 119025 является использование сальников, что снижает срок действия устройства. А общим недостатком модели является отсутствие мер механизмов, которые бы гарантировали защиту картера и коленвала в случае аварийных ситуаций, и гарантировали бы избежать образования трещин в пружине или рессоре. But both models have disadvantages. So, the disadvantage of model 119025 is the use of oil seals, which reduces the life of the device. A common disadvantage of the model is the lack of measures of mechanisms that would guarantee the protection of the crankcase and crankshaft in case of emergency, and would guarantee to avoid the formation of cracks in the spring or spring.

Целью создания данной модели является устранение вышеуказанных недостатков, использовав модели иа 119025 и иа 125509 как прототипы. Данная цель достигается следующим образом. Рис. 1 The purpose of creating this model is to eliminate the above disadvantages, using models IA 119025 and IA 125509 as prototypes. This goal is achieved as follows. Figure: 1

Модель состоит из двух систем главной и аварийной: The model consists of two main and emergency systems:

1. Главная система построена на базе модели иа 125509. 1. The main system is based on the IA 125509 model.

Во избежание использования сальников используются две рессоры рис. 1.8 To avoid the use of oil seals, two springs are used fig. 1.8

Крепящиеся к частей шатуна 1,7 с помощью восьми шпилек 10) Attached to parts of the connecting rod 1.7 with eight studs 10)

Длина рессор при изготовлении для определенного типа двигателей корректируется таким образом, что собственная частота колебаний рессор совпадала с частотой оборотов двигателя в оптимальном режиме. The length of the springs during manufacture for a certain type of engine is corrected in such a way that the natural oscillation frequency of the springs coincides with the engine speed in the optimal mode.

2. Противоаварийная система как и в модели 119025 шатун состоит из двух частей 1.7 движущихся друг относительно друга благодаря втулкам 5 с таким покрытием как во вкладышах 13, крепящиеся к коленвала. Зазор 6) между двумя опорными поверхностями 11) рассчитываются с учетом упругости рессор и предела прочности рессор. Вместо пружины в модели иа 119025 между двумя частями 1.7 шатуна является упругая прокладка 12. 2. Anti-crash system as in model 119025 the connecting rod consists of two parts 1.7 moving relative to each other thanks to the bushings 5 with the same coating as in the liners 13, attached to the crankshaft. The gap 6) between the two bearing surfaces 11) is calculated taking into account the elasticity of the springs and the tensile strength of the springs. Instead of a spring in the IA 119025 model, there is an elastic gasket 12 between the two parts 1.7 of the connecting rod.

Обе части шатуна 1.7 изготавливаются из титана. Нижняя часть шатуна имеет гнезда для двух втулок 5 и пустоту 2 в которой кроме гнезда для втулки место для движения вниз верхней части 7 шатуна вместе с фиксирующей гайкой 3. Между фиксирующей гайкой и втулкой является упругая прокладка 4. И довершает противоаварийную систему металлический карман 9, состоящий из двух стаканов, которые крепятся вместе с рессорами булавками к верхней 7 и нижней части шатуна и заходят один в один. Both parts of the 1.7 connecting rod are made of titanium. The lower part of the connecting rod has seats for two bushings 5 and a void 2 in which, in addition to the seat for the bushing, there is a place for downward movement of the upper part 7 of the connecting rod together with the locking nut 3. Between the locking nut and the sleeve is an elastic gasket 4. And the metal pocket 9 completes the emergency system, consisting of two glasses that are attached together with the springs with pins to the upper 7 and the lower part of the connecting rod and go one into one.

А работает шатун так, как модель иа 125509. And the connecting rod works like the model IA 125509.

Усовершенствованный таким образом кривошипно-шатунный механизм работает так: при сгорании топлива поршень начинает давить на шатун, а шатун на коленвал (рис. 2). В данный момент сила реакции оси коленвала на шатун является максимальной (сила F1), так как шатун и колено коленвала лежат на одной прямой ОА. Сила реакции оси коленвала F2 в точке Ml будет равна нулю так как прямая ОМ1 будет перпендикулярна прямой АМ1, где точка О лежит на центре оси вращения коленвала а точка А является центром шарнирного соединения поршня. The crank mechanism improved in this way works as follows: when the fuel burns, the piston starts to press on the connecting rod, and the connecting rod on the crankshaft (Fig. 2). At the moment, the reaction force of the crankshaft axis on the connecting rod is maximum (force F1), since the connecting rod and the crankshaft knee lie on the same straight line OA. The reaction force of the crankshaft axis F2 at the point Ml will be equal to zero, since the line ОМ1 will be perpendicular to the line AM1, where point O lies at the center of the crankshaft axis of rotation and point A is the center of the piston articulation.

Flo кроме силы реакции оси коленвала шатун за счет энергии поршня преодолевает сопротивление силы трения колес автомобиля о дорогу силы инерции и суммарной силы сопротивления трения всех деталей автомобиля движущегося. На рисунке это сила Fp движения. Сила упругости F пружины пружинного аккумулятора энергии выбирается меньше векторной суммы Fp + F1 сил движения и сил реакции оси коленвала в точке МО и точках недалеко от нее удалены, соответствующие начала движения поршня от верхней мертвой точки к нижней. Сила упругости должна быть больше векторную сумму сил F2 + Fp равной 0 + Fp, F упругости больше Fp, чтобы пружинный амортизатор-аккумулятор мог выпрямиться отдавая энергию. Flo, in addition to the reaction force of the crankshaft axis, the connecting rod, due to the energy of the piston, overcomes the resistance of the friction force of the wheels of the car against the road, the force of inertia and the total resistance force of friction of all parts of the car in motion. In the figure, this is the force Fp of the movement. The elastic force F of the spring of the spring energy accumulator is chosen less than the vector sum Fp + F1 of the forces of motion and reaction forces of the crankshaft axis at the point MO and points not far from it, corresponding to the beginning of the piston movement from top dead center to bottom. The elastic force must be greater than the vector sum of forces F2 + Fp equal to 0 + Fp, F elasticity greater than Fp, so that the spring shock absorber-accumulator can straighten giving energy.

В результате пружина амортизатора сжимается в момент начала рабочего хода поршня и выпрямляется начиная с точки Ml отдавая аккумулированную энергию для ускорения вращения коленвала, тем самым повышая КПД двигателя. Рис. 2 As a result, the spring of the shock absorber is compressed at the moment of the beginning of the working stroke of the piston and is straightened starting from the point Ml, giving up the accumulated energy to accelerate the rotation of the crankshaft, thereby increasing the efficiency of the engine. Figure: 2

Противоаварийная система работает так. В случае нормальной работы, когда рессоры цели, срабатывает только зазор, только в моменты максимальных нагрузок, когда две половины шатуна касаются друг к другу. И только в случае выхода из строя рессор, для сохранения целостности шатуна начинают работать две половины шатуна, движущихся друг относительно друга благодаря втулкам, а до этого они двигались в холостом режиме дублируя деформацию рессор. Стакан 9 предотвращает попадание осколков металла в коленвала или к картера в случае разрушения рессор. The emergency system works like this. In the case of normal operation, when the springs are the target, only the gap is triggered, only at moments of maximum loads, when the two halves of the connecting rod touch each other. And only in the event of a failure of the springs, to preserve the integrity of the connecting rod, two halves of the connecting rod, moving relative to each other thanks to the bushings, begin to work, and before that they moved in idle mode duplicating the deformation of the springs. Glass 9 prevents metal fragments from entering the crankshaft or the crankcase in the event of the destruction of the springs.
