Description
Technical field
The utility model relates to a kind of general gasoline engines cylinder head, particularly post rod type general gasoline engines cylinder head.
Background technique
At present, post rod type general gasoline engines cylinder head commonly used comprises die cavity, valve guide bushing, air valve seat ring, suction tude, outlet pipe, firing chamber, outbreak surface, air channel and spark plug mounting hole.Die cavity is positioned at the end face of cylinder head, and outbreak surface is positioned at the bottom surface of cylinder head.Be furnished with 2 jogger holes and 2 spring seats in die cavity, be furnished with rocker arm bracket between jogger hole and spring seat, 2 rocking arms can be installed on the rocker arm bracket, jogger hole, rocker arm bracket and spring seat are arranged in parallel successively.Be provided with porose respectively in the spring seat, valve guide bushing is housed in the hole, with the coaxial corresponding air valve seat ring that is provided with of this valve guide bushing, the axis of valve guide bushing and air valve seat ring is vertical with plane, described firing chamber, between valve guide bushing and the air valve seat ring connection chamber is arranged, and the three forms current path makes die cavity be communicated with the firing chamber, and the suction tude and the corresponding with it respectively connection chamber of outlet pipe that are positioned on the cylinder head two side are communicated with.The firing chamber is positioned at outbreak surface, four angles on the outbreak surface are provided with two positioning holes and two bolt connecting holes, be used for connect box and gasoline engine cylinder head, two positioning holes are arranged on one side of outbreak surface, and two bolt connecting holes are arranged on a limit in addition of outbreak surface.This positioning hole that be arranged in parallel is easy to generate when locating and rocks, and causes the location inaccurate, the firing chamber air-loss.Simultaneously, the degree of depth of die cavity generally at about 1/2 of cylinder head height overall, has taken duct space, and therefore the air channel that is provided with is generally narrower, is unfavorable for ventilation and heat.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of accurate positioning, is beneficial to the post rod type general gasoline engines cylinder head of air discharging and radiating.
For solving the problems of the technologies described above, the post rod type general gasoline engines cylinder head that the utility model adopts, comprise die cavity, valve guide bushing, air valve seat ring, suction tude, outlet pipe, the firing chamber, outbreak surface, air channel and spark plug mounting hole, described die cavity is positioned at the end face of cylinder head, outbreak surface is positioned at the bottom surface of cylinder head, jogger hole successively has been arranged in parallel in described die cavity; rocker arm bracket and spring seat; in the described spring seat valve guide bushing is housed; with the coaxial corresponding air valve seat ring that is provided with of this valve guide bushing; the axis of described valve guide bushing and air valve seat ring is vertical with plane, described firing chamber; between described valve guide bushing and the air valve seat ring connection chamber is arranged; and the three forms current path die cavity is communicated with the firing chamber; be positioned at described suction tude on the cylinder head two side and outlet pipe and be communicated with separately connection chamber respectively; described firing chamber is positioned at described outbreak surface; four angles of outbreak surface are provided with two positioning holes and two bolts hole; described positioning hole becomes the diagonal angle to arrange with bolt hole separately; described depth of cavity is no more than 2/5 of cylinder head height overall, and described air channel height is greater than 10mm.
Described suction tude and outlet pipe outer end end face assume diamond in shape, and the major axis of this rhombus is vertical with outbreak surface respectively.
The utility model is by becoming the diagonal angle to arrange separately with two bolts hole two positioning holes on the outbreak surface, the mode that this diagonal angle is arranged, positioning hole can accurately be located when connect box and gasoline engine cylinder head, and good airproof performance has avoided the energy of firing chamber to reveal; Simultaneously, with depth of cavity be controlled at the cylinder head height overall 2/5 in, making has enough space that bigger air channel is set under the die cavity, the height in air channel can reach more than the 10mm, is beneficial to air discharging and radiating.For further implementing this model utility better, suction tude and outlet pipe outer end end face assume diamond in shape, and the major axis of rhombus is vertical with outbreak surface respectively, so that install and dismounting.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
As depicted in figs. 1 and 2, post rod type general gasoline engines cylinder head comprises die cavity 1, valve guide bushing 2, air valve seat ring 3, suction tude 4, outlet pipe 5, firing chamber 6, outbreak surface 14, air channel 15 and spark plug mounting hole 7.Die cavity 1 is positioned at the end face of cylinder head, and outbreak surface 14 is positioned at the bottom surface of cylinder head.At die cavity 1 groove bottom land be arranged in parallel successively two jogger holes 8, two rocker arm brackets 9 and two spring seats 10.The opposite side corresponding with die cavity 1 is provided with outbreak surface 14, than outbreak surface slightly lower be provided with firing chamber 6.Valve guide bushing 2 is housed in the spring seat 10, with these valve guide bushing 2 coaxial corresponding air valve seat rings 3 that are provided with, the axis of valve guide bushing 2 and air valve seat ring 3 is vertical with outbreak surface 14, between valve guide bushing 2 and the air valve seat ring 3 connection chamber 11 is arranged, and the three forms current path makes die cavity 1 be communicated with firing chamber 6.Suction tude 4 and outlet pipe 5 are positioned at the sidewall of cylinder head, are communicated with separately connection chamber 11 respectively.
