Problems solved by technology
The rocker arm frame installation base of the existing bimetallic cylinder head is a sheet-shaped cast iron core, which is wrapped and embedded in the cylinder head through the four legs under the sheet-shaped body. The plane of the iron core is used to install and fix the rocker arm frame, the plane of the iron core is the same height as the upper plane of the cylinder head, but since the four-legged iron core is wrapped inside the cylinder head, the iron core and the cylinder head are closely combined, and a large amount of heat from the cylinder head is transferred to the iron core at high temperature, and The heat of the iron core cannot be effectively dissipated, which makes the temperature of the entire cylinder head higher, thereby reducing the thermal stability and working reliability of the bimetallic cylinder head

Embodiment Construction
[0011] Embodiments of the present invention will be described below with reference to the drawings. Such as figure 1 ,figure 2, image 3 As shown, a bimetallic cylinder head includes a cylinder head base body 5, a rocker arm frame mounting base 7 and a support plate 1, and is characterized in that: the rocker arm frame mounting base 7 has three cylindrical legs 3 embedded in the cylinder In the head base 5, the three legs 3 are rigidly connected to the support plate 1 of the rocker arm frame installation base 7 through the support ribs 2, and the lower plane of the support plate 1 of the rocker arm frame installation base 7 is in contact with the concave surface at the end of the cylinder head. There is a gap 9 between the planar upper surfaces 6 . The upper plane of the support plate 1 is fixedly connected with the rocker arm frame. Through holes 4 are provided in the axial direction of the three cylindrical legs 3 . Through the through hole 4, the mounting base of the ro...

The present invention relates to cylinder head for motorcycle, and is especially well heat dissipating double-metal cylinder head. The cylinder head includes cylinder head body, rocker rack mounting seat and bearing board, and features that the rocker rack mounting seat has three cylindrical feet embedded inside the cylinder head body and connected rigidly to the bearing board via bearing ribs and there is some interval between the bearing board and the end of the cylinder head. The upper plane of the bearing board is fixed to the rocker rack. The present invention has less heat absorption, good heat dissipating effect, raised heat stability and work reliability, and can lower noise of motorcycle.
Description
technical field [0001] The invention relates to a motorcycle cylinder head, in particular to a bimetallic cylinder head with good heat dissipation. Background technique [0002] Motorcycle engines are equipped with cylinder heads. Bimetallic cylinder heads refer to the addition of a cast iron (or other material with a low expansion coefficient) rocker arm mounting base in the aluminum alloy engine cylinder head base to install valve rocker arms. The frame can reduce the thermal expansion and deformation of the rocker arm frame to achieve the purpose of reducing engine noise. Since the bimetallic cylinder head has a certain effect on reducing the noise of the motorcycle engine, it is currently widely used. The rocker arm frame installation base of the existing bimetallic cylinder head is a sheet-shaped cast iron core, which is wrapped and embedded in the cylinder head through the four legs under the sheet-shaped body. The plane of the iron core is used to install and fix the ...
