Motorcycle vibration damping type frame

Abstract

The invention discloses a motorcycle vibration damping type frame, which comprises a stand tube, a front slant supporting tube, a main girder tube, a left main supporting tube, a right main supporting tube, a left tail tube, a right tail tube, a left rear slant tube, a right rear slant tube, an engine lower cross tube, a left lower bracket tube, a right lower bracket tube, and a main girder reinforced tube. The stand tube, the front slant supporting tube, the main girder tube, and the main girder reinforced tube are connected together through a large left main girder panel and a large right main girder panel, two edges of a front main girder reinforced panel arranged on the outer surface of the main girder tube are respectively corresponding to the edges of the large left main girder panel and the large right main girder panel, and joints among all related components are positioned on same welding line when welding; a U-shaped notch of the front main girder reinforced panel is clamped into an excircle of the stand tube, two straight edges of a semicircle reinforced construction member which is connected with the outer surface of the front slant supporting tube are respectively corresponding to the edges of the large left main girder panel and the large right main girder panel, and all interconnecting members are welded on same welding line when welding. The motorcycle vibration damping type frame has the advantages of enhanced intensity and rigidity, reduced vibration and optimized integral stressed frame structure, more harmonious appearance, and prolonged service life of related parts.

Description

technical field [0001] The invention relates to a motorcycle frame, in particular to a vibration-damping off-road motorcycle frame with greatly increased strength and reduced self-vibration. Background technique [0002] As the skeleton of the entire motorcycle, the motorcycle frame plays a vital role. The engine power system is fixed on the vehicle frame through mounting lugs, the front steering system is connected to the vehicle frame through the riser, and the rear suspension system is connected to the flat fork and the vehicle frame through the shock absorber. Appearance covers, fuel tanks, shelves, seat cushions, etc. also directly or indirectly act on the frame. Therefore, the frame needs to have sufficient strength and rigidity to meet the requirements of use. On August 20, 2008, Chinese utility model ZL200720125200.5 disclosed an off-road motorcycle frame.

Problems solved by technology

On August 20, 2008, Chinese utility model ZL200720125200.5 disclosed a off-road motorcycle frame. This structure provides a frame structure using a round tube as the main pipe. The holes are connected by the same shaft, which puts forward higher requirements on the welding strength of the frame and the strength of the shaft, which increases the cost, and the assembly process is complicated and the assembly strength is high

On December 6, 2006, the Chinese utility model patent ZL200520142045.9 disclosed a motorcycle frame. This structure simply provides reinforcing ribs between the standpipe and the front support tube, which cannot increase the strength and rigidity of the frame.

This structure has defects such as complex processing technology, high welding difficulty, complex fixture structure, and difficult to control product consistency.
