Abstract
The utility model discloses a cylinder head that is provided with a bush for an independent valve push rod, which comprises a cylinder head body provided with a bush mounting hole with an opened cooling water cavity. A bush for valve push rod is arranged in the bush mounting hole and two ends of the bush for valve push rod are fixed at the cylinder head body and close the cooling water cavity of the cylinder head body. One end of the joint between the bush for valve push rod and the cylinder head body is interference fit and the other end is clearance fit with a sealing ring arranged in the fit. The utility model simplifies the inner structure of the cylinder head body, optimizes the inner water cavity, improves the yield and quality of the cylinder head casting, solves the sealing problem between the push rod hole and the water cavity and enhances the reliability of the engine.
Description
Technical field
The utility model relates to a kind of engine cylinder cap, relates in particular to a kind of engine cylinder cap with valve actuating push rod lining.
Background technique
Because the work characteristics of motor need be cooled off the motor of proper functioning to guarantee the proper functioning of motor, is the water cavity of cylinder cap around the lining, its structure is very complicated.At present, general motor is when the casting cylinder cap, no valve actuating push rod lining, the valve actuating push rod hole directly processes on cylinder head, and pushrod bushing is to cast in cylinder cap, must process the valve actuating push rod lining after the casting, owing to the even phenomenon of valve actuating push rod jacket wall thickness ununiformity of casting after reason can cause processing, reduce the reliability of motor, and the interior casting sand of water cavity is difficult for being eliminated totally so like this, can make cylinder head internal structure complexity simultaneously, the reject rate height.
The model utility content
Technical problem to be solved in the utility model provides a kind of simplification cylinder head internal structure, optimizes the cylinder head of the independent valve actuating push rod lining of having of inner water cavity.
For solving the problems of the technologies described above, the technical solution of the utility model is: the cylinder head with independent valve actuating push rod lining, comprise the cylinder head body, described cylinder head body is provided with the open lining mounting hole of cooling water chamber, in the described lining mounting hole valve actuating push rod lining is installed, described valve actuating push rod lining two ends are fixed on the described cylinder head body and with the cooling water chamber sealing of described cylinder head body, one end of the junction of described valve actuating push rod lining and described cylinder head body is an interference fit, and the other end is to be provided with seal ring in Spielpassung and the gap.
As a kind of improvement, the upper end of the junction of described valve actuating push rod lining and described cylinder head body is an interference fit, and the lower end is to be provided with seal ring in Spielpassung and the gap.
Owing to adopted technique scheme, cylinder head with independent valve actuating push rod lining, comprise the cylinder head body, described cylinder head body is provided with the open lining mounting hole of cooling water chamber, in the described lining mounting hole valve actuating push rod lining is installed, described valve actuating push rod lining two ends are fixed on the described cylinder head body and with the cooling water chamber sealing of described cylinder head body, one end of the junction of described valve actuating push rod lining and described cylinder head body is an interference fit, and the other end is to be provided with seal ring in Spielpassung and the gap; Simplify the cylinder head internal structure, optimized inner water cavity, improved cylinder cap casting yield rate and quality, solved the sealing problem of push-rod hole and water cavity, improved the reliability of motor.
The upper end of the junction of described valve actuating push rod lining and described cylinder head body is an interference fit, and the lower end is to be provided with seal ring in Spielpassung and the gap; During installation, adopt and be pressed into mode, structural adjustment is simple, and sealing is reliable, helps changing the valve actuating push rod lining.
Description of drawings
Accompanying drawing is the utility model embodiment's a structural representation.
Embodiment
As shown in drawings, cylinder head with independent valve actuating push rod lining, comprise cylinder head body 1, described cylinder head body 1 is provided with the open lining mounting hole of cooling water chamber, in the described lining mounting hole valve actuating push rod lining 2 is installed, described valve actuating push rod lining 2 two ends are fixed on the described cylinder head body 1 and with cooling water chamber 3 sealings of described cylinder head body 1, described valve actuating push rod lining 2 is an interference fit with an end of the junction of described cylinder head body 1, and the other end is to be provided with seal ring 4 in Spielpassung and the gap.Simplify the cylinder head internal structure, optimized inner water cavity, improved cylinder cap casting yield rate and quality, solved the sealing problem of push-rod hole and water cavity, improved the reliability of motor.
Described valve actuating push rod lining 2 is an interference fit with the upper end of the junction of described cylinder head body 1, and the lower end is to be provided with seal ring 4 in Spielpassung and the gap.Can adopt the mode of being pressed into to install, structural adjustment is simple, and sealing is reliable, helps changing the valve actuating push rod lining like this.
When the casting cylinder cover blank, cast out bottom outlet in the position that the valve actuating push rod lining is installed, this hole can be used as the sand removal hole again, helps casting sand is removed clean; Before installing the valve actuating push rod lining is machined, guarantee uniform wall thickness, improve the reliability of motor; During installation, adopt the mode that is pressed into, an interference fit is adopted in sealing, and one with the seal ring sealing, helps changing the valve actuating push rod lining like this.
