Description

Semi-dry cylinder jacket anti-wear ring of automobile engine

Technical Field

The utility model belongs to the technical field of automobile engine, concretely relates to semi-dry cylinder jacket ring that wear-resistants of automobile engine.

Background

The antiwear ring is a thin-wall annular structure and is embedded at the large end position of an inner hole of a semi-dry cylinder sleeve of the engine, and the wall thickness is generally 2-4 mm; the height is determined by the specific technical parameters of the engine, the upper end of the piston is flush with the spigot of the cylinder sleeve, and the lower end surface of the piston is 1-3mm higher than the upper plane of the first piston ring when the upper dead center of the engine piston is positioned; the inner hole of the wear-resistant ring is in clearance fit with the head of the piston and does not participate in friction, so the wear-resistant ring is made of gray cast iron, the cost is low, and the processability is good; the outer wall of the antiwear ring is in small clearance fit with the antiwear ring groove at the head of the cylinder sleeve. In recent years, with the higher environmental protection requirement, a plurality of new technologies are applied to the aspect of engine emission, but the technology of using the antiwear ring is the most direct and most effective means with the lowest cost. The main functions of the antiwear ring are as follows: high-temperature and high-pressure fuel gas which hinders the engine from working descends through the piston head; because the diameter of the inner hole of the antiwear ring is smaller than that of the inner hole of the cylinder sleeve, the excessive engine oil pushed upwards by the piston ring can be prevented from participating in combustion when the piston moves upwards; when the carbon deposit on the inner wall of the antiwear ring is accumulated to a certain thickness, the head of the piston can blow the carbon deposit on the inner wall of the antiwear ring out of the engine body when the piston moves upwards, and abrasive wear caused by the fact that the carbon deposit falls into an engine cylinder sleeve is reduced.

But current ring of wearing adopts the welded mode to install when the installation, uses the back for a long time at ring of wearing, needs to resist and grinds the ring and clear up or change, but the ring welding of wearing is sheathe in at half-dry cylinder, and it is big to get rid of the degree of difficulty, and the operation is complicated, is unfavorable for the maintainer to change, is unfavorable for improving maintenance efficiency.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an automobile engine semi-dry cylinder jacket ring that wear, can be simple and convenient will wear ring installs in the cylinder liner to convenient dismantlement, the regular antithetical couplet carbon deposit of maintainer on the ring clears up, and the change of ring that wear, convenient operation improves maintainer's maintenance efficiency greatly, with the problem of proposing in solving above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

the utility model provides an automobile engine half-dry cylinder jacket ring that wear-resistants, includes half-dry cylinder jacket and the ring body that wears, the ladder groove has been seted up to the wet-type portion opening part of half-dry cylinder jacket, be provided with the internal thread on the lateral wall in ladder groove, set up threaded blind hole on the ladder groove, the countersunk head screw hole has been seted up on the ring body that wears, the lateral part of ring body that wears is provided with internal thread matched with external screw thread, wear-resistants ring body installs the wet-type portion opening part at half-dry cylinder jacket through interior hexagonal bolt, interior hexagonal bolt passes countersunk head screw hole and threaded blind hole from last to screw in.

Preferably, the side of ring body wear-resisting is seted up flutedly, the recess sets up to the V-arrangement groove.

Preferably, chamfers are arranged on the upper and lower side portions of the antiwear ring body, and the angle of each chamfer is set to be 30-45 degrees.

Preferably, the height of the antiwear ring body is set to be 8-18 mm.

Preferably, the upper surface of the antiwear ring body and the upper end surface of the wet part of the semi-dry cylinder sleeve are positioned on the same horizontal plane.

Preferably, the sum of the length of the countersunk head threaded hole and the length of the threaded blind hole is equal to the length of the hexagon socket head cap screw.

Compared with the prior art, the beneficial effects of the utility model are that:

through the use of internal thread and external screw thread, can be simple and convenient will wear ring body and install in semi-dry cylinder liner, through countersunk head screw hole, screw thread blind hole and hexagon socket head cap screw's cooperation, can resist the further fixed of ring body of wearing, and can judge according to hexagon socket head cap screw's position whether the ring body of wearing is installed in place, and the maintainer of being convenient for overhauls and changes, and convenient operation improves work efficiency.
