Embodiment Construction

[0018] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below through specific embodiments in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0019] The invention provides a hollow valve bridge guide rod, such as figure 1 , figure 2 shown, including:

[0020] Guide rod 102, one end of the guide rod 102 is slidingly connected with the valve bridge 101, the other end of the guide rod 102 is fixedly connected with the cylinder head 100, and the axial direction of the guide rod 102 is also provided with a central hole 103 (such as figure 2 shown); since the cylinder head 100 has structures such as air passages and water passages inside, the installation hole of the guide rod 102 is generally designed as a blind hole, and the...

Abstract

The invention provides a hollow valve bridge guide rod. The hollow valve bridge guide rod comprises a guide rod body, one end of the guide rod body is in sliding connection with a valve bridge, the other end of the guide rod body is in sliding connection with a cylinder cover, and a center hole is further formed in the axis direction of the guide rod body. According to the hollow valve bridge guide rod provided by the invention, since the center hole exists, air in a mounting hole can be smoothly exhausted, and no compressed air exists; and meanwhile, the bottom shrinkage amount is increased,press fitting is convenient, and the weight of the guide rod body is reduced.

Description

technical field [0001] The invention belongs to the technical field of cylinder head cooling, and in particular relates to a hollow valve bridge guide rod. 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 the blind hole, the...
