Problems solved by technology

[0006] The dead speed car in the prior art is only suitable for playing in open and unmanned places, and cannot be used as an ordinary bicycle; if the dead speed car in the forward direction is stepped on the pedal in the opposite direction, the vehicle will immediately stop moving forward and move backward; the dead speed car If it is used as a bicycle on the road, it will bring great hidden dangers and harm to traffic safety.
[0007] Many people not only love the ordinary bicycle as a means of transportation, but also love the dead speed car that can be played for entertainment; however, under the conditions of the existing technology, if they want to realize the functional purposes of the two vehicles at the same time, they can only have the ordinary bicycle and the dead speed car together. , and the functional purpose of two vehicles cannot be realized in one vehicle
In other words, people hope that a human-powered vehicle can be used both as an ordinary bicycle and as a dead speeder; however, in the prior art, the flywheel of an ordinary bicycle and the flywheel of a dead speeder have different purposes and structures. principle, it is impossible to have the functions of two flywheels on the same flywheel

Embodiment 1

[0124] First, a general text description of the inventive system in the first embodiment is as follows.

[0125] The inventive system of this embodiment includes a driven gear assembly and a rear wheel; said driven gear assembly includes: a driven gear 1 , an installation shaft 2 , and a hub 3 . Note: The passive gear is also called flywheel.

[0126] The two ends of the vehicle frame body 20 and the installation shaft 2 are in a fixed connection; the body of the installation shaft 2 is in a rotational connection with the hub 3 .

[0127] The parts mentioned above are all very mature in the prior art, and quite a lot of introductions have also been made in the front.

[0128] The content to be described below is the special technology contributed by the present invention.

[0129] The inventive system of this embodiment also includes: a ratchet and pawl mechanism;

[0130] The ratchet and pawl mechanism includes: a ratchet 4 provided with ratchet teeth, a wheel cover 5, and...

Embodiment 2

[0187] This embodiment illustrates how the ratchet 4 and the hub 3 are fixedly connected.

[0188] combine Figure 39 and Figure 40 Be explained. Figure 39 It is a schematic diagram of the inventive system in the second embodiment; Figure 40 yes Figure 39 Partial enlarged view of II in the center, the magnification ratio is listed as 1.8:1;

[0189] exist Figure 39 and Figure 40 Among them, numeral 3 is a hub of the prior art, and its head is provided with external threads.

[0190] The number 4 is the ratchet 4 of the present invention, which is provided with an internal thread.

[0191] The same as the assembly technology of the prior art is: the external thread of the hub is screwed into the internal thread of the ratchet 4, and tightened with force.

[0192] The difference from the assembly technology of the prior art is: before the above-mentioned assembly, first coat the external thread with glue, or coat the internal thread, or coat the internal and extern...

Embodiment 3

[0197] This embodiment illustrates again how the ratchet 4 and the hub 3 are fixedly connected.

[0198] combine Figure 41 Be explained. In this embodiment, it is necessary to modify the hub of the prior art, the head of which cancels the external thread and changes it to a conical shape with a small slope, the left side is larger and the right side is smaller; the ratchet 4 cancels the internal thread and changes it to a small slope conical hole , the aperture is larger on the left and smaller on the right. The slope of the hub matches the shape of the slope of the ratchet 4, and the slope matches.

[0199] Before assembly, use two-component or three-component adhesive to coat the slope of the hub and the slope of the ratchet 4, then close the two, and use a clamp to stand for a period of time under the clamped state, and the glue will occur. After the chemical reaction, it is completely cured.

[0200] Relying on the action of multi-component glue, the ratchet 4 and the...

Abstract

The invention relates to the technical field of bicycles, and discloses a transmission system for a two-wheeled vehicle powered manually. In order to fulfill two flywheel functions on the same flywheel, the technical scheme is provided as follows: the transmission system for the two-wheeled vehicle powered manually is characterized by comprising a ratchet wheel (4), a wheel cover (5) and two action components, wherein the ratchet wheel (4) is provided with ratchet teeth; each action component comprises a switching handle (6), a rotating shaft (7), a pawl (8), a steel ball (9) and a spring (10); a driven gear (1), each spring (10), the corresponding steel ball (9) and the corresponding pawl (8) are propped against one another sequentially; and each rotating shaft (7) is rotatably connected with the wheel cover (5), extends out of the wheel cover (5), and is connected with the corresponding switching handle (6). The transmission system for the two-wheeled vehicle powered manually has the beneficial effects that by switching, the two-wheeled vehicle powered manually can be in a mode of a common bicycle, can also be in a mode of a fixed gear bicycle, and can even be in an innovative reversing mode.

Description

technical field [0001] The invention relates to the technical field of bicycles and bicycles, in particular to a transmission system of a two-wheeled rickshaw. Background technique [0002] Bicycles are the most common means of transportation for ordinary people to go out. [0003] In recent years, there has appeared an alternative sports vehicle that is popular with some trendy teenagers: the dead speeder; the dead speeder is also called a dead speeder bicycle or a fixed-toothed car, and is collectively referred to as a dead speeder below. [0004] At first glance, the dead speed car looks like an ordinary bicycle, but after comparison, there are the following situations: 1. The dead speed car is stepping on the pedal forward, and the vehicle is moving forward; At the beginning of the moment, the vehicle stops moving forward, and if the pedal is stepped on in the opposite direction, the vehicle moves backward. 2. If you step on the pedal of an ordinary bicycle in the forw...
