Abstract
The utility model relates to a front shock absorbing device of a motor tricycle. Lower ends of a front fork stem and a shock absorber are provided with a U-shaped shock absorbing rocker arm, the lower end of the front fork stem is in hinged engagement connection with one arm end of the U-shaped shock absorbing rocker arm, the other arm end of the U-shaped shock absorbing rocker arm is provided with a wheel shaft assembling hole, and the lower end of the shock absorber is in hinged engagement connection with a lower support lug disposed on a bottom portion between two arms of the U-shaped shock absorbing rocker arm. A hinged hole of the lower support lug is not higher than a front fork stem hinged hole and the wheel shaft assembling hole which are arranged at the two ends of the U-shaped shock absorbing rocker arm. Through lowering the position of the hinged hole at the lower end of the shock absorbing rocker arm, a distance between the hinged hole of the lower end of the shock absorbing rocker arm and the hinged hole of the front fork stem is the smallest during no-load and is the largest during heavy load, thereby not only achieving the purpose of comfortableness during no-load, but also increasing bearing capacity of the shock absorber.
Description
Technical field
The utility model relates to a kind of shock absorption device, refers to a kind of motor-tricycle front damping device especially.
Background technology
At present, the preceding damping of the straight barrel type of two-wheeled motorcycle is adopted in the preceding damping of motor-tricycle mostly, the upper end that also is front fork stem is fixedly mounted in the mounting hole of lower connecting plate, the lower end of front fork stem is plugged at the bottom of the damping in the tube, be provided with damping spring in the front fork stem, be provided with damping oil in tube and the front fork stem at the bottom of the damping, be provided with seal ring and oil sealing at the bottom of the damping between the upper end of tube and the front fork stem.There is following defective in the front shock absorber of this structure: the interface oil sealing of tube reduces damping effect owing to the push-and-pull friction causes the oil sealing leakage of oil at the bottom of front fork stem and the damping, reduces service life; Because the grafting area of contact of tube is big at the bottom of front fork stem and the damping, and plugging position not only will bear straight-line motion power, but also will bear vertical, horizontal thrust, cause travel in damping performance descend; Because the deadweight and the load-carrying of motor-tricycle all are far longer than two-wheeled motorcycle, the crashworthiness of damping and the demand that load can not satisfy motor-tricycle cause safety misadventure easily before the straight barrel type.
Also there is the part motor-tricycle to adopt the rocking arm damping, front fork tube extends downward the front wheel spindle corresponding height through upper and lower connecting plate, perhaps front fork tube extends downward the front wheel spindle corresponding height from lower plate, the upper end of bumper is connected with the top of front fork tube is hinged, and the lower end of bumper and front fork tube is connected with the damping rocking arm is hinged respectively.The shock absorption device of this structure, because the damping rocking arm is the straight line level type, hinged hole, bumper lower end is higher than the linear position of hinged hole, front fork tube lower end and wheel shaft assembly opening.When unloaded, the distance between the hinged hole, hinged pitch-row front fork tube lower end, bumper lower end is maximum, and to the top power minimum that bumper makes progress, damping effect is relatively poor, and ride comfort is also poor.Distance during heavy duty between the hinged hole, hinged pitch-row front fork tube lower end, bumper lower end diminishes, and the top power that bumper is made progress becomes big, and load-carrying capacity is relatively poor.Bumper lower fulcrum movement in a curve conversion on its damping rocking arm is unreasonable.
The utility model content
The purpose of this utility model provide a kind ofly strengthen the damping effect of motor-tricycle when unloaded, the motor-tricycle front damping device of bumper load-carrying capacity when promoting heavy duty.
For achieving the above object, the technical solution adopted in the utility model is: a kind of motor-tricycle front damping device comprises front fork tube, bumper, hinged being connected of upper journal that the upper end of bumper and front fork tube top are provided with.The lower end of described front fork tube, bumper is provided with U type damping rocking arm, hinged being connected of arm end of the lower end of front fork tube and U type damping rocking arm, another arm end of U type damping rocking arm is provided with the wheel shaft assembly opening, hinged being connected of down journal that the bottom between the lower end of bumper and U type damping rocking arm two arms is provided with.
The hinged hole of down journal is not higher than the hinged hole of front fork tube and the wheel shaft assembly opening at U type damping rocking arm two ends.
The beneficial effects of the utility model are: adopt U type damping rocking arm, the hinged hole of damping rocking arm lower end is not higher than the hinged hole of front fork tube and the wheel shaft assembly opening at U type damping rocking arm two ends.According to lever principle: the distance between the hinged hole of damping rocking arm lower end and the hinged hole of front fork tube is near more, the damping rocking arm is just big more to the top power of bumper, distance between the hinged hole of damping rocking arm lower end and the hinged hole of front fork tube is far away more, and the damping rocking arm is just more little to the top power of bumper.Utilize the movement in a curve of hinged point and lever principle to adjust distance between the hinged point, satisfy the demand that stress curve changes.When motor-tricycle is unloaded, the hinged hole site of front fork tube is the highest, U type damping rocking arm is downward-sloping, the hinged hole horizontal of hinged pitch-row front fork tube of damping rocking arm lower end is nearest, bumper is in the amount of compression minimum rating, very little downward pressure is arranged, and bumper just has comfortable elastic force effect, promptly makes bumper have damping effect preferably.During heavy duty, U type damping rocking arm is the center of circle with the wheel shaft assembly opening, movement in a curve is done in the hinged hole of damping rocking arm lower end and the hinged hole of front fork tube, make the hinged hole and the distance between the hinged hole of front fork tube of damping rocking arm lower end become big, the hinged hole of damping rocking arm lower end and the distance between the front wheel spindle diminish, according to lever principle, the heavy duty of car load has reduced the demand to damper pressure, has promptly promoted the load-carrying capacity of bumper.
The position in the hinged hole of the utility model by reducing damping rocking arm lower end, make the distance between the hinged hole of hinged pitch-row front fork tube of damping rocking arm lower end: minimum when unloaded becomes big during heavy duty; The purpose of traveling comfort when both having reached unloaded has increased the load-carrying capacity of bumper again.Be to kill two birds with one stone.Thereby increased the service life of bumper, reduced maintenance, cut operating costs.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
