At present, existing integrated wheel of bicycle typically uses magnesium alloy or carbon fiber offhand, can not be with internal speed-changing
Device connects, or integrated wheel is connected excessively complexity with internal speed changer.And speed changer peripheral hardware, the attractive in appearance of vehicle body is on the one hand influenceed, separately
One side speed changer cannot be protected, and easy laying dust is soaked.
The content of the invention
Technical problem to be solved in the utility model is：Overcome the deficiencies in the prior art, there is provided built in a kind of integrated wheel
Speed changer structure, it is built in securely in integrated wheel so as to become device speed.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is：A kind of integrated wheel built-in variable speed device structure,
Including integrated wheel, internal speed changer and piece is compressed, connecting portion is provided with the center of the integrated wheel, the connecting portion, which has, to be used for
The internal shape cavity of accommodating internal speed changer, the internal speed changer have cylindrical shell, passed through between the internal speed changer and connecting portion
Screw thread or the connection of spline or step, the compression piece is enclosed on one end of internal speed changer, and by screw or is bolted to one
On the connecting portion of wheel, so that internal speed changer is pressed on the connecting portion of integrated wheel.
Further, when internal speed changer is connected with connecting portion by step, the case surface of the internal speed changer is provided with
Multiple steps, the structure of the internal shape cavity of integrated wheel connecting portion are engaged with the step on the shell of internal speed changer, the compression piece
It is enclosed on one end that internal speed changer top bar is relatively large in diameter.
Further, connected between the connecting portion and integrated wheel by spoke, the integrated wheel, spoke and connecting portion are one
It is body formed.
After employing above-mentioned technical proposal, the major part of internal speed changer of the present utility model is embedded in the company at integrated wheel center
In the internal shape cavity of socket part, it is connected, and is further fixed by compressing piece, Ci Zhongqian with integrated wheel by screw thread or spline or step
The structure for entering formula enables internal speed changer to prevent dust deposit, prevents rainwater from soaking, and increases the service life；It is of the present utility model
The internal shape cavity of internal speed changer and connecting portion is connected by screw thread or spline or step, and connection is more firm, can be with any material
Integrated wheel links；The utility model novelty simple in construction, and it is attractive in appearance, durable, there is very strong practicality and promotional value.
