Embodiment
1-4 specifically describes the utility model below in conjunction with accompanying drawing.
This rocker shaft bed is applicable to the cylinder cap of Dual Over Head Camshaft, and its structure is bilateral symmetry basically, has concentrated simultaneously the oil-way system of engine braking apparatus in rocker shaft bed, and mostly the distribution of all lubricant oil of cylinder cap is to realize by this structure.
The utility model is in line with the principle that reduces component, in design, consider the spatial arrangement and the mechanical property of rocker shaft bed and camshaft holder simultaneously, again in conjunction with the cylinder cap assembly, at Fig. 1,2, the motor rockshaft seat assembly has been shown in 4, comprise superposed two rocker shaft holes 1,2, be positioned at two camshaft holes 3 of bottom, 4, be positioned at the bolt hole 7 of the secure rocker of rocker shaft hole axial direction, 13, be distributed in the secure rocker seat bolt hole 8 of rocker shaft bed assembly both sides, 14 and the oil duct 5 that is communicated with of cylinder cap, and connect to advance, the crossbeam oil duct 6 of exhaust both sides.As shown in Figure 3, the trend of oil circuit is: from the lubricant oil of cylinder cap by the mail gallery holes on the rocker shaft bed 10, be assigned to as the crossbeam oil duct 6 that divides oil duct, be communicated with between crossbeam oil duct 6 and the bolt hole 7,13,14, lubricant oil flows to bolt hole 7 by crossbeam oil duct 6, lubricates one of them camshaft bearing journal (position of camshaft hole 4) through the connecting passage 12 between bolt hole 7 and the camshaft hole 4 again.The lubricated of another one camshaft bearing journal (position of camshaft hole 3) is to flow to bolt hole 14 by crossbeam oil duct 6, lubricates through the connecting passage between bolt hole 14 and the camshaft hole 3 16 again.The purpose that crossbeam oil duct 6 and bolt hole 13 are communicated with is to allow lubricant oil be transported on the pitman arm shaft, is assigned to other camshaft bearing journal by the oil duct on the pitman arm shaft.Crossbeam oil duct 6 is simultaneously also to the engine braking apparatus fuel feeding.
In the motor rockshaft seat assembly; the size of rocker shaft diameter is Φ 10～50mm; camshaft hole 3,4 sizes are Φ 10～65mm; the size of the distance A between two camshaft holes is 50～300mm; be of a size of 30～250mm apart from B between two rocker shaft holes; the height C of rocker shaft bed is of a size of 50～150mm, and the distance D between the bolt hole 8,14 is of a size of 50～400mm, and the width E of rocker shaft bed is of a size of 10～80mm.
In the motor rockshaft seat assembly, consider the layout of three or three above bolts; In Fig. 2, between bolt hole 8 and the rocker shaft hole 2 is 10～70mm apart from F; between rocker shaft hole and the camshaft hole is 20～100mm apart from G; the position dimension H of bolt hole 8 on the rocker shaft bed width direction is 10～70mm; between two secure rocker bolts is 10～100mm apart from I, and bolt 7 is 20～100mm apart from the camshaft center apart from G.
