Abstract
The utility model relates to a front fork riser of moving away to avoid possible earthquakes, including the tubulose body, the tail end of tubulose body is equipped with reinforcement section and end fender section, reinforcement section with end fender section with the tubulose body is through drawing technology and harmomegathus technology integrated into one piece. The utility model discloses a draw many times and the harmomegathus technology obtains heterotypic structure, makes the front fork riser of shock attenuation reduce product weight guaranteeing the unchangeable prerequisite of intensity, reduces the annex on the front fork riser of shock attenuation to improve product machining precision, reduction in production cost.
Description
Technical Field
The utility model relates to a steering mechanism's technical field, concretely relates to front fork riser of moving away to avoid possible earthquakes.
Background
The shock-absorbing front fork vertical pipe is an important component for determining the steering performance of the shock-absorbing front fork, one end of the existing shock-absorbing front fork vertical pipe is sleeved with a bottom blocking sleeve, and the bottom blocking sleeve and the shock-absorbing front fork vertical pipe are welded and fixed. In order to ensure the strength of the shock-absorbing front fork stem, a reinforcing tube is usually added inside the shock-absorbing front fork stem. The structure of the existing shock-absorbing front fork vertical pipe causes the assembly process to be complex, the requirement on welding is high, the production cost is not favorably controlled, and the market demands on the light weight of products.
SUMMERY OF THE UTILITY MODEL
For solving the above-mentioned problem that exists among the prior art, the utility model provides a front fork riser of moving away to avoid possible earthquakes, including integrated into one piece's reinforcement section and end fender section, under the prerequisite of proof strength, reduced the weight of front fork riser of moving away to avoid possible earthquakes, the reduction of spare part and the simplification of technology have reduced manufacturing cost.
The utility model discloses a following technical scheme realizes: the shock-absorbing front fork vertical pipe comprises a tubular body, wherein a reinforcing section and a bottom baffle section are arranged at the tail end of the tubular body, and the reinforcing section, the bottom baffle section and the tubular body are integrally formed through a drawing process and an expansion and contraction process.
Further, the outer diameter of the reinforcing section is equal to the outer diameter of the tubular body, and the inner diameter of the reinforcing section is smaller than the inner diameter of the tubular body.
Further, the inner diameter of the bottom baffle section is equal to the inner diameter of the tubular body, and the outer diameter of the bottom baffle section is larger than the outer diameter of the tubular body.
Further, the concentricity of the vertical tube of the shock-absorbing front fork is within 0.05.
Compared with the prior art, the utility model have following advantage:
1. The utility model discloses no longer need the welding end spacer sleeve, eliminate because of the insecure influence to the steering performance of end spacer sleeve welding.
2. The utility model discloses an integrated into one piece shaping draws back excircle and lathes the processing again, guarantees the utility model discloses a concentricity improves whole car steering performance within 0.05.
3. The utility model discloses need not increase the reinforcement pipe, reduced follow-up production processes.
The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The first embodiment is as follows:
Referring to fig. 1, the shock-absorbing front fork vertical pipe is used for connecting a lower yoke plate with a frame of a motorcycle or an electric vehicle and comprises a tubular body 1, wherein a reinforcing section 2 and a bottom baffle section 3 are arranged at the tail end of the tubular body, and the reinforcing section, the bottom baffle section and the tubular body are integrally formed through a drawing process and an expansion and contraction process. The shock-absorbing front fork vertical pipe with the special-shaped structure is obtained through multiple drawing and expanding processes, so that the weight of the shock-absorbing front fork vertical pipe is reduced on the premise of ensuring that the strength is unchanged, and accessories on the shock-absorbing front fork vertical pipe are reduced, so that the product processing precision is improved, and the production cost is reduced.
Referring to fig. 1, in the present embodiment, the outer diameter of the reinforcing section 2 is equal to the outer diameter of the tubular body 1, and the inner diameter of the reinforcing section 2 is smaller than the inner diameter of the tubular body 1.
Referring to fig. 1, in the present embodiment, the inner diameter of the bottom block section 3 is equal to the inner diameter of the tubular body 1, and the outer diameter of the bottom block section 3 is larger than the outer diameter of the tubular body 1. Through integrated into one piece's end fender section, no longer need the welding end spacer sleeve, eliminate because of the influence of end spacer sleeve welding insecure to the steering performance.
The wall thickness of the reinforcing section 2 is larger than that of the tubular body, so that a reinforcing pipe is not required to be added, and the subsequent production procedures are reduced.
in the present embodiment, the concentricity of the suspension fork stem is within 0.05. Because the vertical tube of the shock-absorbing front fork with the special-shaped structure is integrally processed, the drawn outer circle is machined, the concentricity of the front fork of the shock absorber is ensured to be within 0.05, and the steering performance of the whole vehicle is improved.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and are not limited, and although the present invention has been described in detail with reference to the embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with other equivalents without departing from the spirit and the scope of the present invention, which should be covered by the claims of the present invention.
