Steam cylinder head device possessing torsion bar

Abstract

The invention discloses a cylinder head device with a torsion bar, which comprises a cylinder head, a cam shaft group, a swinging arm unit, two space torsion bars and a locking unit, the cylinder head is provided with a cylinder head body, a first supporting wall and a second supporting wall which are spaced and four upright posts which connect two side ends of the first supporting wall and the second supporting wall, a pair of mounting holes which are opposite are formed on the first and the second supporting walls, the swinging arm unit is arranged between the first supporting wall and the second supporting wall, which can swing relative to the cylinder head, the cam shaft group is penetratingly arranged in the two mounting holes, which can drive the swing arm unit to swing, the two torsion bars are upright posts which are bestrid to connect both sides of the first supporting wall and the second supporting wall, and the two torsion bars are locked on the upright post of the cylinder heat through the locking unit. The first supporting wall and the second supporting wall are connected through the two torsion bars, and structure rigidity of the cylinder head is improved to resist imperfect influence which is brought by heat resistance and deformation.

Description

【Technical field】 [0001] The invention relates to a cylinder head arrangement, in particular a cylinder head arrangement with a torsion bar. 【Background technique】 [0002] Such as figure 1 As shown, the existing cylinder head device 1 is installed and fixed on a cylinder block (not shown in the figure) to control the entry of oil and gas into the cylinder body, and to discharge the exhaust gas after combustion. The cylinder head device 1 has a cylinder head body 11, a holding seat 12 arranged on the cylinder head body 11, a seat cover 13 provided on the holding seat 12, and a seat cover 13 between the holding seat 12 and the seat cover 13. Between the camshaft 15, and a locking group 16. [0003] The holder 12 has a first lower bearing wall 121 and a second lower bearing wall 122 arranged at intervals on the cylinder head body 11, and two opposite sides of the first and second lower bearing walls 121 and 122 are respectively arranged. The lower column 123. A screw hole ...

AI Technical Summary

Problems solved by technology

[0010] However, since there is no connecting member between the first and second support walls 22, 23, thermal deformation during operation easily causes deformation and displacement of the first and second support walls 22, 23, and the overall structural rigidity appears Relatively insufficient, resulting in the enlargement of the valve clearance and affecting the output effect of the cylinder
