Detailed Description
As used in the specification and in the claims, certain terms are used to refer to particular components. As one skilled in the art will appreciate, manufacturers may refer to a component by different names. This specification and claims do not intend to distinguish between components that differ in name but not function. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to. The following description is of the preferred embodiment for carrying out the invention, and is made for the purpose of illustrating the general principles of the invention and not for the purpose of limiting the scope of the invention. The scope of the present invention is defined by the appended claims.
The present invention will be described in further detail below with reference to the accompanying drawings, but the present invention is not limited thereto.
Examples
As shown in fig. 1, a tricycle speed change transmission device comprises an inner speed change hub 1, a flywheel assembly 2 and a speed change driving seat 3; the inner speed changing hub 1 is provided with a driving chain disc 11, the inner speed changing hub 1 is further provided with a middle shaft 12, a speed changing gear assembly is arranged inside the inner speed changing hub 1 and is in transmission connection with the middle shaft 12, and the speed changing gear assembly can drive the inner speed changing hub 1 to rotate on the middle shaft 12; the flywheel component 2 is sleeved on the middle shaft 12, and the flywheel component 2 is in transmission connection with the speed change gear component, so that the flywheel component 2 can drive the speed change gear component to work when rotating; the speed-changing driving seat 3 is sleeved on the middle shaft 12, and the speed-changing driving seat 3 is in transmission connection with the speed-changing gear assembly, and can drive the speed-changing gear assembly to change gears. (wherein the internal shift drum 1 can refer to the SHIMINO internal shift drum series product).
Preferably, the speed change driving seat 3 can drive the speed change gear assembly arranged on the inner speed change hub 1 to gradually change between 3-8 gears.
The working principle and the assembly relation are as follows: as shown in fig. 2, the tricycle speed-changing transmission device is assembled on the frame 4 through a middle shaft 12 during assembly, the driving chain plate 11 is in transmission connection with a rear wheel driving chain plate 5 arranged at the rear end of the frame 4 through a chain, the flywheel assembly 2 is in transmission connection with a pedal driving chain plate 6 arranged at the front end of the frame 4 through a chain, and the speed-changing driving seat 3 is connected with a speed-changing driving handle arranged on a handlebar.
When a driver steps on a pedal to drive the pedal driving chain wheel 6 to rotate, the flywheel component 2 can drive the variable speed gear component arranged in the inner variable speed hub 1 to work, so that the inner variable speed hub 1 is driven to rotate along the middle shaft 12, the driving chain wheel 11 further arranged on the inner variable speed hub 1 drives the rear wheel driving chain wheel 5 to rotate, and finally, the tricycle drives the rear wheel to rotate and move forwards; when the speed is required to be changed, a driver can toggle the driving handle arranged on the handle to control the speed changing driving seat 3 to drive the speed changing gear assembly to change the gears, so that the speed of the tricycle can be adjusted.
Compared with the prior art, its advantage lies in: the structure of the tricycle is changed into that the gear internal speed change hub is durable and almost free of maintenance, and the speed change gear is contained in the internal speed change hub, so that the appearance of the tricycle is more attractive and simultaneously resists the trouble of rain and mud.
While the foregoing description shows and describes the preferred embodiments of the present invention, it is to be understood, as noted above, that the invention is not limited to the forms disclosed herein, but is not intended to be exhaustive or to exclude other embodiments and may be used in various other combinations, modifications, and environments and is capable of changes within the scope of the inventive concept described herein, as determined by the above teachings or as determined by the skill or knowledge of the relevant art. And that modifications and variations may be effected by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
