Description
Technical field
The present invention relates to the technical field of motorcycle, specifically a kind of support steering mechanism of two front wheels motorcycle.
Background technique
Existing motorcycle generallys use two-wheeled or tricycle structure, and the wheel positioned at front is then the turning machine of motorcycle
Structure, driver change the direction of travel of motorcycle by operation rotation handlebar, and the motorcycle of tricycle structure is more compared with Double-wheel structure
It is easy to be grasped by driver.And traditional motor tricycle generallys use single-wheel in the posterior structure of preceding, two-wheel, this structure is then
There are problems that steering stability, cannot turn in the case where speed height, otherwise can turn on one's side；In addition, traditional three
Wheeled motorcycle is also merely able to be suitable for relatively flat road surface, and when road surface has compared with macrorelief, the front-wheel of traditional tricycle is with after
All there is biggish security risk in the shock-damping structure of wheel.
In recent years, each motorcycle manufacturer starts to explore the motorcycle of research and development two front wheels, using the near front wheel arranged side by side
And off-front wheel, rear-wheel are then single-wheel, the near front wheel and off-front wheel are all steering mechanism, while guiding Vehicular turn, the entirety of vehicle
Gravity centre distribution is more reasonable, also more stable when driving.
In Piaggio Co., Ltd's application, patent that publication No. is CN103153769, disclosing a kind of tool, there are two forwards
To the tiltable motorcycle of wheel, vehicle frame, two steering front wheels are provided in the motorcycle, are rotationally attached to the vehicle frame and
Be rigidly connected to the steering tube of support component, each support component respectively for each deflecting roller, include in steering group steering tube,
Two lateral columns and the transverse arm of going forward being separately connected with steering tube, lateral column, lower preceding transverse arm, upper rear transverse arm and lower rear transverse arm, and go forward
Transverse arm, lower preceding transverse arm, upper rear transverse arm and lower rear transverse arm play the role of supporting car body, in motorcycle driving, transverse arm of going forward,
Transverse arm, upper rear transverse arm and lower rear transverse arm rise and fall with turning or road surface simultaneously before lower and steering tube relatively rotates, to guarantee
The stabilization of car body.
The supporting mechanism of existing two front wheels motorcycle is relatively complicated, in order to guarantee that left and right sides mechanism cooperates
The fixation seating portion that often centre is connected with vehicle frame carries out the hollow out of many places complexity, processes relative difficulty, while to obtain
Corresponding support strength prevents from being broken using middle, and each stressed member also has to reach sufficiently large size, with guarantee by
Power position has sufficiently large solid section, so that car weight be made to increase.Existing steering mechanism is generally passed using the connecting rod of rigidity
It is dynamic, to guarantee that the normal work of two front wheels motorcycle steering mechanism then more increases weight gain trend, and existing steering mechanism
It is more demanding between fitness component, so need higher machining accuracy, steering operation and not flexible in vehicle use, in addition
Energy consumption also can relative increase.
