Front wheel rocker arm structure for double front wheels motorcycle and front wheel swing tilt structure

Abstract

The invention discloses a front wheel rocker arm structure for a double front wheels motorcycle. The front wheel rocker arm structure comprises a left rocker arm, a right rocker arm and a middle rocker arm which are independent, the left rocker arm and the right rocker arm are movably connected with the middle rocker arm correspondingly, and the middle rocker arm is movably connected with a motorcycle head pipe through a fixing shaft. At least one of an upper rocker arm and a lower rocker arm of a front wheel swing tilt mechanism of the double front wheels motorcycle adopts a front wheel rocker arm structure comprising the left rocker arm, the right rocker arm and the middle rocker arm which are independent and movably connected with one other. According to the front wheel rocker arm structure for the double front wheels motorcycle and the front wheel swing tilt structure, three-stage rocker arm structures connected movably replace single rigidity rocker arm structures in the prior art, so that the stress of a motorcycle body swing tilt mechanism is more uniform, the size corresponding to the single support component is minimized to save materials and reduce motorcycle weight, and manufacturing is more simple. A secondary shock absorber structure can also play the role of secondary shock absorption, body vibration when the motorcycle travels on the complex road surface is reduced, and the comfort of a driver is improved.

Description

technical field [0001] The invention relates to the technical field of motorcycles, in particular to a front wheel swing arm structure and a front wheel swing and tilt structure of a double front wheel motorcycle with a multi-stage damping structure. Background technique [0002] Existing motorcycles usually adopt a two-wheel or three-wheel structure, and the wheel at the front is the steering mechanism of the motorcycle. The driver can change the direction of travel of the motorcycle by operating and turning the handlebar. The structure is easier for the driver to grasp. However, traditional three-wheeled motorcycles generally adopt a structure with one wheel in front and two wheels behind. This structure has steering stability problems, and it cannot be turned at high speeds, otherwise rollover will occur; in addition, traditional The three-wheeled motorcycle also can only be applicable to comparatively flat road surface, and when the road surface has larger ups and downs...

Problems solved by technology

[0007] However, the upper transverse part and the lower transverse part adopted in the front wheel tilting mechanism of the existing dual-front-wheel motorcycle are all rigid rod-shaped structures, which need to carry the weight of the vehicle frame and the driver in use. Therefore, in order to obtain the corresponding support strength and prevent breakage during use, the upper and lower transverse parts must be of sufficient size to meet the requirement that the middle force-bearing position of the rod-shaped structure has a sufficiently large solid section. Need to go through a relatively complex processing technology to obtain

In addition, the above-mentioned parallelogram structure formed in the rocking and tilting mechanism itself only plays the role of adaptive deformation, and the deformation range is small. The deformation adaptability of the parallelogram is poor in complex road conditions. The vibration during driving is still all resolved by the traditional shock absorber. When the road condition is poor, there will still be a large vibration feedback to the driver
