Main foot stool structure of motorcycle

Abstract

The invention relates to a motorcycle main foot rest structure. An outer cover of a right crankcase of an engine and the two sides of a front end of a left crankcase are provided with pivot holes having a threaded section and step part. The step part is sleeved with a first lining. The main foot rest is provided with a convex sheet having a perforation. A second lining can be inserted into the perforation and is pressed against a surface of a reinforced part of a stopping body. A bolting element is inserted through the second lining, the reinforced part of the stopping body and the first lining to be fixed on the threaded part. The convex sheet of the main foot rest can be rotated on the second lining. The main foot rest of a motorcycle is arranged at two sides of the front end of the crankcase of the engine so as to be positioned just at two sides of the front ends of the left and right crankcases and under cranks. Thus, the main foot rest can change the position for parking the motorcycle in accordance with the change of the center of the gravity of the engine to achieve stability for parking the motorcycle and increase the minimum height above ground of the motorcycle, thereby avoiding friction with the ground due to the inadequate distance between the main foot rest and the ground. At the same time, the overall design change engineering of the motorcycle becomes simpler.

Description

technical field [0001] The invention relates to a main tripod structure of a motorcycle, in particular to a structure in which the main tripod of the motorcycle is arranged on both sides of the front end of the engine crankcase. Background technique [0002] In order to facilitate parking, general motorcycles usually have a main leg under the motorcycle, please refer to figure 1 As shown, the main tripod 2 of the motorcycle 1 is mainly arranged under the cross tube 12 of the motorcycle 1 frame 11, the cross tube 12 is welded with a fixed piece 13, and the main tripod 2 is connected by a bolt 21 Bolted on the fixed piece 13, and utilize a spring 22 to be connected between the main foot frame 2 and the fixed piece 13, so that the main foot frame 2 is bounced up conveniently, wherein, the engine 14 of the motorcycle 1 is suspended and arranged on The top of the cross tube 12, and the fixed piece 13 that the main foot frame 2 is locked is then equivalent to being positioned at ...

AI Technical Summary

Problems solved by technology

However, since the engine 14 is often designed along with the body of the motorcycle 1, when the center of gravity of the engine 14 moves toward the rear of the car body due to the change of the design, the length of the fixed piece 13 must be extended backwards. To facilitate the main leg 2 can also change the position along with the center of gravity of the engine 14, this change will easily cause the moment of the fixed piece 13 to change and weaken

[0003] Yes, someone has developed another main tripod structure, see figure 2 As shown, the main tripod 3 is arranged below the front end of the engine 4 of the motorcycle (the center of gravity), and the lower end of the engine 4 is provided with a pivotal lug 41, and the main tripod 3 is pivotally connected to the pivotal joint. On the lifting lug 41, by locking the main tripod 3 on the engine 4, when the design of the engine 4 is changed, the main tripod 3 can move with the center of gravity of the engine 4, although this design can make the main tripod 3 is located at the center of gravity of the engine 4. However, since the bottom of the engine 4 is closer to the ground, when the motorcycle is driving on an uneven road, the main leg 3 is likely to hit the road, resulting in damage to the main leg 3
