The fixing method of the nut in this installation structure is to embed the nut directly into the through hole, and the surface of the nut is in contact with the through hole, and the stop torque is generated through the contact surface. When it is larger, the material in contact with the surface of the air filter and the nut is softened due to the load exceeding the bearing limit, and the stop effect cannot be achieved. The nut rotates with the bolt under the reaction force of the bolt, which further damages the air filter and makes the air filter The limit effect of the nut on the nut is invalid, resulting in a small tightening torque of the bolt or the bolt cannot be unscrewed normally, and finally the air filter cannot be installed or disassembled

Embodiment Construction
[0016] refer to Figure 1 to Figure 4 , a motorcycle air filter installation structure of the present invention, comprising an air filter housing 1, the two ends of the air filter housing 1 are provided with positioning ears 11 for installation, the positioning ears 11 correspond to the air of the motorcycle frame The position of the filter mounting hole is provided with a through hole 111 for the bolt 6 to pass through. The lower end surface of the positioning ear 11 is in contact with the motorcycle frame, and the upper end surface of the positioning ear 11 is fixedly connected with a connecting mounting plate, which corresponds to The position of the through hole 111 is provided with an internal thread for bolt connection with the frame of the motorcycle, and the air filter is tightly connected with the frame of the motorcycle by cooperating with the bolt 6 through the internal thread.
[0017] Further, the connection installation plate includes a metal sheet 2, and the met...

The invention discloses a motorcycle air filter installation structure which comprises an air filter shell. The two ends of the air filter shell are provided with positioning lugs for installation. A through hole allowing a bolt to penetrate therein is formed in the position, corresponding to an air filter installation hole of a motorcycle frame, of each positioning lug. The lower end face of each positioning lug makes contact with the motorcycle frame. The upper end face of each positioning lug is fixedly connected with a connection installation plate. The position, corresponding to the corresponding through hole, of each connection installation plate is provided with an internal thread used for being in bolted connection with the motorcycle frame. The structure of a traditional air filter that nuts are embedded into positioning lugs for bolted fastening is replaced, the effect between the nuts and the air filter is transformed to the effect between the connection installation plates and the air filter, the arm of force of locking torque is greatly prolonged, and the problem that the air filter loses efficacy for the nut locking effect when torque is too large, and therefore normal assembly and disassembly cannot be achieved is avoided. The motorcycle air filter installation structure is simple in structure, easy and convenient to assemble and disassemble and low in production cost.
Description
technical field [0001] The invention relates to an air filter, in particular to a motorcycle air filter installation structure. Background technique [0002] The air filter is a device to purify the air. The outside air enters the carburetor through the air filter, and then mixes with the oil to form oil and gas for the motorcycle engine. Its main function is to prevent dust and sand from entering the engine and ensure the normal operation of the engine. , Delay cylinder wear, so the air filter is an essential part of the motorcycle. [0003] Due to the characteristics of low production cost and light weight of plastic, plastic air filters are widely used in existing motorcycles, and the installation of plastic air filters and motorcycle frames is mainly through the threaded connection of bolts and nuts. The installation structure is: air The two ends of the filter housing are provided with positioning lugs for installation. The positioning lugs correspond to the position o...
