摘要： An engine head gasket includes a base layer, an upper layer, and a lower layer. The base layer includes a base layer inner edge. The engine head gasket further includes an anti-preignition wrap defining a cylinder opening and wrapped around the base layer inner edge. The engine head gasket is configured with a combustion seal and selective thicknesses to direct a combustion sealing load to a cylinder block. The anti-preignition wrap shields angular corners of the base layer inner edge from a cylinder to limit preignition.

摘要： A new method of manufacturing a torque-transmitting component is provided. The method includes providing a flat blank to a transfer press having a plurality of stations and performing a plurality of pressing operations, in which the flat blank is formed into a cup shape, rough splines are formed on the cup shape, and the rough splines are further pressed to define smooth splines. The component includes a continuous smooth inner diameter defined by a punch of the transfer press and a plurality of smooth splines defined by a die of the transfer press. The minor diameter of the splines is not machined to form the splines.

摘要： A rocker arm includes a pair of sidewalls disposed along a heightwise direction so as to be opposed to each other. The sidewalls define a space to house a roller and have opposed portions extending in the heightwise direction relative to adjacent portions which are adjacent to the opposed portions. The opposed portions have thinner portions having smaller thicknesses than the adjacent portions.

摘要： A method of forming one or more tie rods that includes flattening a main body of a wire in a first selected plane to form a flattened main body, further flattening selected portions of the flattened main body in a second plane perpendicular to the first plane to form one or more break back regions, and then passing the wire through a punch press machine to form one or more coined regions in one or more ends of the wire, thus forming the tie rod.

摘要： A rocker arm has two side walls and two webs which run transversely with respect to the side wall. The webs connect the side walls to one another on end-side sections, wherein a valve stem support is configured on one of the webs, and a spherical cap is configured on the other web. A cam roller is arranged in a roller pocket which is delimited by the webs and the side walls. The cam roller is mounted rotatably on a roller axle which is fixed in the side walls. Projections are arranged within the roller pocket such that they are spaced apart from the respective web to guide the cam roller. The projections extend from the side walls in the direction of the cam roller to form guide surfaces which interact with end surfaces of the cam roller.

摘要： Connecting rod ultrasonic-assisted splitting machining method and a machining device thereof, relating to the field of machining of a connecting rod. The machining device comprises a rack, a fixing block, a sliding block, a sliding block base, a vertical locking oil cylinder, a wedge-shaped pull rod, an adjusting block body, etc. By means of the method and the device thereof, the range of the material used for splitting the connecting rod is enlarged, the splitting force required during the splitting of the connecting rod, deformation of fracture surfaces, residues generated during the splitting process, out-of-roundness of big end holes of the connecting rod, and other situations are reduced, and the engaging accuracy of the connecting rod and the joint face of a connecting rod cover and the assembly quality of the connecting rod are improved.
