Description

Изобретение относитс к области двигателестроени .The invention relates to the field of engine building.
Известна головка цилиндра двигател внутреннего сгорани с воздушным охлаждением, содержаща корпус с выхлопными и всасывающими каналами, гнездами дл клананов, каналами дл охлаждающего воздуха и опорной поверхностью дл клапанной коробки, состо щей из основа1ш и крыщки дл размещени в ней распределительного механизма с коромыслами , имеющими сферические опоры, закреплешП )1е на опорных щтшльках, ввернутых в осноBaime корпуса и заканчиваюищхс нарезкой дл гайки креплени крышки клапанной коробки 1 Однако вследствие неравномерного теплового расширени корпуса, опорных шпилек, клапана и штанги толкател измен ютс зазоры в клапанах , что приводит к наруще1шю фаз газораспределени и повышению шума при работе двигател .The famous cylinder head of an air-cooled internal-combustion engine, comprising a housing with exhaust and suction channels, nests for clans, cooling air channels and a bearing surface for a valve box consisting of a base 1sh and a flap for accommodating a distribution mechanism with rocker arms having spherical supports, fasteners) 1e on bearing pins, screwed into the base of the body and ending with cutting for the nut securing the valve cover 1 However, due to uneven thermal expansion of the housing, the studs, the valve and the push rod change gaps in the valves, which leads to disruptive valve timing and increased noise during engine operation.
Целью изобрете1ги йвл етс уменьшение теплового зазора путем охлаждени onopiniix шштек. Это достигаетс тем, что в предлагаемой головке опорные шш1льки размещены вThe aim of the invention is to reduce the thermal gap by cooling the onopiniix pin. This is achieved by the fact that in the proposed head the support bars are located in
каналах дл охлаждающего воздуха и выполнены ступенчатыми с двум по сами креплени - нижним жестким в основании корпуса на резьбе и средним в перемычке над каналами дл охлаждающего воздуха - со свободной посадкой на по се бурта увеличенного диаметра.cooling air ducts and are made stepwise with two fastenings on their own — the bottom rigid one at the base of the body on the thread and the middle one in the bridge over the cooling air channels — with a free fit on the cross of an enlarged diameter.
Кроме того, опорные поверхности корпуса и соответственно основани клапанной коробки выполнены в виде ступеней, причем плоскость нижней ст)Т1ени расположена в зоне клапанов, а плоскость верхней ступени - в зоне опорных шпилек. Это позвол ет уменьшить длину стержней клапанов и их вли ние на зазоры при тепловом расширении во врем работы двигател .In addition, the bearing surfaces of the housing and, accordingly, the base of the valve box are made in the form of steps, with the plane of the lower stage being located in the area of the valves and the plane of the upper stage in the area of the studs. This reduces the length of the valve stems and their effect on the gaps during thermal expansion during engine operation.
На фиг. 1 изображена описываема головка штиндра, продольный разрез; на фиг. 2 - то же. Поперечный разрез; на фиг. 3 - то же, вид сверху.FIG. 1 shows the described cylinder head, a longitudinal section; in fig. 2 - the same. Cross section; in fig. 3 - the same, top view.
Головка цилиндра имеет корпус 1 с каналам и гнездами дл выхлотП)1х 2 и всасывающих 3 клапанов, а также каналами 4 дл охлаждающего воздуха. Опорные поверхности 5 и 6 корпуThe cylinder head has a housing 1 with channels and sockets for exhaust ports (1x 2) and suction 3 valves, as well as channels 4 for cooling air. Support surfaces 5 and 6
