Abstract

The invention provides a valve bridge guide rod with exhaust passages. The valve bridge guide rod comprises a guide rod body, wherein one end of the guide rod body is in sliding connection with a valve bridge, and the other end of the guide rod body is fixedly connected with a cylinder cover; the bottom end of the guide rod body is also provided with the first exhaust passage and the second exhaust passage; the axis of the first exhaust passage is located on the central axis of the guide rod body, and the second exhaust passage communicates with the upper end of the first exhaust passage; andthe axis of the second exhaust passage is perpendicular to the axis of the first exhaust passage. According to the valve bridge guide rod with the exhaust passages, the exhaust passages are additionally arranged and used for exhausting air in a mounting hole, so that the valve bridge guide rod is pressed in place accurately; and due to the existence of the exhaust passages, the contraction amountof the bottom is increased, and press mounting is convenient.

Description

technical field [0001] The invention belongs to the technical field of cylinder head cooling, and in particular relates to a valve bridge guide rod with an exhaust passage. Background technique [0002] At present, the application of the valve bridge guide mechanism on the engine is more and more. As an important part of the guide mechanism, the valve bridge guide rod is used more and more. Valve bridge guide rods generally adopt a cylindrical structure and are fixed on the datum surface of the cylinder head. Through the contact of the cylindrical surface, the valve bridge is guided in a fixed direction. The installation tolerances of the valve bridge guide rod itself have a great influence on the guide function. If the verticality deviation between the valve bridge guide rod and the guide reference plane is too large, the original guiding function will be lost, which will instead cause abnormal wear of the valve bridge. When the valve bridge guide rod is installed on th...
