Abstract

The utility model relates to a cylinder pad, particularly to an all metal cylinder pad used for a diesel engine. The utility model is characterized in that a pad body is a single-layer metal plate; a cylinder hole is sealed by arc-shaped ripples pressed and formed at the cylinder hole by the pad body; a water hole, an oil hole and a tappet hole are all sealed by oil-resistant rubber rings, the inner parts of the oil-resistant rubber rings are embedded with single or a plurality of metallic frames which are connected, or are sealed by oil-resistant rubbers directly pressed and cast on the pad body; the pad body, the water hole, the oil hole and the tappet hole are connected in an interference fit or cemented mode. The cylinder pad can enhance the reliability and the durability of an engine, and enhance the work efficiency, and the cylinder pad is favorable to environment protection.

Description

Diesel engine full-metallic head gasket

The utility model relates to a kind of head gasket, the full-metallic head gasket of using on especially a kind of diesel engine.

Main between engine body and the cylinder cap by the head gasket sealing, what present domestic 90% head gasket was still asbestos slate and the iron plate of making a spurt is composited, wherein main sheet material is Ashestos plate, its environmental-protecting performance is poor, more external developed countries have forbidden producing, the cylinder mouth of asbestos slate composite pad, water hole guard ring adopt the metal bound edge to make more, and its withstand voltage properties is poor, motor easily towards cylinder, leak.

The purpose of this utility model is the deficiency that overcomes above-mentioned prior art, and a kind of reliable performance, stay-in-grade environment protection type diesel engine full-metallic head gasket are provided.

For achieving the above object, the technical solution adopted in the utility model is: a kind of diesel engine full-metallic head gasket, comprise pad and cylinder-bore, water hole, tappet bore and bolt hole and oilhole on it, and its special way is that pad is the single-layer metal plate.

Above-mentioned cylinder-bore is the arc ripple sealing that the back cushion body forms in the compacting of place, cylinder hole; Water hole, oilhole, tappet bore all are the inner oil resistant rubber ring sealings that single or several metal frames connect that studs with; Pad is to adopt interference fit or the gluing mode that connects to be connected with water hole, oilhole, tappet bore.

Above-described water hole, oilhole and tappet bore can also be by the oil resistant rubber sealing of rheo-die-casting on pad.

The good effect that compared with the prior art the utility model has is; it can not only improve reliability, the durability of motor; reduce the replacing number of times of cylinder pad; increase work efficiency; and aspect the discharging of the use of material and motor; all help environmental protection, moulds of industrial equipment technology is simple, and equipment investment is few.

Below in conjunction with drawings and Examples the utility model is described in further detail.
