Description
Technical Field
The invention relates to the technical field of motor tricycle vibration reduction, in particular to a motor tricycle front suspension vibration reduction device.
Background
The left and right vibration dampers arranged on two sides of the front wheel of the motor tricycle usually adopt straight simple vibration dampers with compression springs, and are vertically connected between a front wheel shaft and a front fork through the vibration dampers with the compression springs to support the vehicle body for bearing and realize vibration reduction. There are three general categories of front shock absorbers in common use today: the front damper without damper is one structure with compression spring sleeved to the damper column and installed inside the damper cylinder of the front fork to absorb the impact and vibration via the expansion and contraction of the compression spring under the impact of external force. The structure of the inner spring type front shock absorber is that a compression spring is arranged in an inner shock absorbing cylinder, a piston rod is arranged in an outer shock absorbing cylinder, the inner shock absorbing cylinder is simply inserted into the outer shock absorbing cylinder, a piston ring on the piston rod props against the compression spring, a one-way valve is arranged between the inner shock absorbing cylinder and the outer shock absorbing cylinder, a small hole for damping oil to pass through is arranged on the piston rod, when the front wheel is impacted to enable the outer shock absorbing cylinder to go upwards, damping oil in the shock absorber continuously goes upwards through the one-way valve and the small hole on the piston rod, when the damping force is not large, the outer shock absorbing cylinder continuously goes upwards, so that the compression spring is compressed, when the space in the outer shock absorbing cylinder is smaller, the damping is increased, and the outer shock absorbing cylinder can be prevented from being impacted with the inner shock absorbing cylinder; when the outer vibration reduction cylinder descends due to the restoring force of the compression spring, damping oil can only flow through the small hole on the piston rod due to the closing of the one-way valve, so that larger damping is formed, and vibration of the compression spring can be damped. And thirdly, an outer spring type front shock absorber, which is basically the same as an inner spring type front shock absorber, except that a compression spring is arranged outside the shock absorber. The three types of shock absorbers are arranged on the front fork to form a supporting piece for bearing a vehicle body and a front wheel steering control piece, so that the requirement on a compression spring used for damping is higher, and if the compression spring is softer, the damping effect is better, the driving feeling is more comfortable, but the shock resistance is poorer; if the compression shell is harder, the impact resistance is enhanced, but the vibration reduction effect is not good enough, and the driving comfort is poor. And the shock absorbers belong to straight simple shock absorbers, are relatively poor in anti-collision capability and bearing capacity when mounted on a front fork, and cannot meet the requirements of a motor tricycle mainly carrying goods. When the straight cylinder type shock absorber is adopted, the weight of the vehicle body is supported by the compression spring, the compression spring is relatively hard, frequent vibration of the compression spring under the impact of external force is obvious, and therefore the shock absorption effect is relatively poor. The structure of the straight-simple shock absorber is relatively complex, the requirement on the compression spring is high, the manufacturing cost of the shock absorber is relatively high, and meanwhile, the problem of relatively poor bearing capacity exists.
Therefore, in order to solve the above problems, there is a need for a motor tricycle front suspension vibration damping device that can
