Description
Technical field
The utility model belongs to shock attenuation unit, particularly relates to a kind of Electrical Bicycle front-wheel shock attenuation unit.
Background technology
The front-wheel shock attenuation unit is the important constituent elements of Electrical Bicycle, and it has outstanding effect for safety and comfortable use Electrical Bicycle.In the prior art, the front-wheel shock attenuation unit is symmetricly set in front vehicle fork two fork leg pipes usually, and based on the spring damping structure.
There is following major defect in the above-mentioned front-wheel shock attenuation unit that is symmetrical arranged the spring damping structure by two fork leg pipes, and its structure of front-wheel shock attenuation unit that is made of two sleeve spring vibration-proof structures is complicated, causes productive costs higher.The technical parameter of two sleeve spring vibration-proof structures is difficult to accomplish in full accord, makes two breeches pipe unbalance stress and the lateral deviation phenomenon occurs, even the stressed accident that a side spring premature fatigue lost efficacy or fractureed that lays particular stress on occurs.In addition, the top that is limited in the outer tube inboard of being pitched the leg tubular construction can only be provided with the sliding sleeve of pipe motion in the confession, and pipe rocks in therefore can not avoiding.Interior pipe rock the swing that will cause front vehicle wheel.
Summary of the invention
The utility model is in order to solve the above-mentioned technical matters that front-wheel shock attenuation unit in the prior art exists, and propose a kind of simple in structure, cost is low, can overcome lateral deviation and front vehicle wheel rocks a kind of Electrical Bicycle front-wheel shock attenuation unit of defective.
The utility model is taked following technical scheme for solving the above-mentioned technical matters that the front-wheel shock attenuation unit exists in the prior art: this shock attenuation unit is managed before comprising vehicle frame, front vehicle fork fork standpipe, damper spring and spring backstop and sliding sleeve, it is characterized in that, the pipe bottom is inlayed and is fixed a sliding sleeve before the vehicle frame, sliding sleeve is provided with the sleeve pipe with its slide joint, the sleeve pipe two ends are respectively equipped with, lower blocking bowl formula bearing, its shoulder of fork standpipe that is arranged in sleeve pipe engages with the lower blocking bowl formula bearing of sleeve pipe, be provided with and pitch the inner covering that standpipe rotates synchronously in the described fork standpipe, inner covering is provided with square axle center hole, fork standpipe upper end is provided with the jam nut that is engaged in retaining bowl bearing on the sleeve pipe, described jam nut upper surface is fixed with spring backstop, the basal surface of spring backstop engages with the top of inner covering, spring backstop is supported with the damper spring of energy storage, the pipe upper end is supported with a mouthful circle before the described vehicle frame, the mouth circle is respectively equipped with both sides up and down, lower blocking bowl formula bearing, wherein lower blocking bowl formula bearing engages with the upper end of damper spring, be plugged in, the handlebar connecting pipe bottom of lower blocking bowl formula bearing is provided with square bar, the square axle center hole slide joint of square bar and inner covering, the bottom of square bar is threaded and is engaged in the nut of inner covering bottom surface, and handlebar connecting pipe top is threaded and is engaged in the jam nut of retaining bowl formula bearing.
The utility model can also be taked following technical measures:
The synchronous rotation of described fork standpipe and inner covering is that the fork standpipe is arranged with keyway, and inner covering is provided with the connecting key that engages with each keyway.
Infratubal port is socketed with the plastic cement dust protecting cap of overlapping casing tube lower blocking bowl bearing before the described vehicle frame.
The beneficial effects of the utility model and advantage are: in this front-wheel shock attenuation unit, joining through inner covering and front vehicle fork fork standpipe by the square bar of handlebar connecting pipe and to constitute the front-wheel direction control mechanism. the square bar of inner covering and handlebar connecting pipe is a sliding block joint, when from the impulsive force of front vehicle wheel through the fork standpipe, jam nut and spring backstop be transmitted to damper spring and when fully being absorbed the square bar of inner covering and handlebar connecting pipe be sliding mode, therefore this device has control of front-wheel direction and the relatively independent characteristics of damper mechanism, its damper mechanism not only makes vehicle frame can avoid vibration, also can avoid handlebar vibration to occur. this device is replaced two sleeve spring vibration-proof structures of existing front-wheel shock attenuation unit and is made damping device structure become simpler by a sleeve spring vibration-proof structure, also avoided simultaneously the technical parameter of existing two sleeve spring vibration-proof structures to be difficult to accomplish on all four defective. the sliding sleeve of pipe and sleeve pipe can ensure that the fork standpipe does not produce and rock before this device vehicle frame, thereby have also overcome the disadvantage that the front vehicle wheel of existing front-wheel shock attenuation unit existence rocks. the utlity model has simple in structure, cost is lower, service-strong is given prominence to advantage.
