Problems solved by technology

The internal transmissions in the current technology generally have the following defects: 1. Manual shifting is required, and automatic shifting cannot be realized; 2. When the internal transmission is shifted to a high-speed gear, if the cadence is decreasing, it is difficult for the transmission to maintain the high-speed gear.

Embodiment 1

[0024] ginseng Figure 1 to Figure 5 As shown, a straight-line pedaling single-wheel direct-drive ring gear center wheel fixed transmission includes: a central shaft 1, a hub 2 and a speed change mechanism arranged between the central shaft 1 and the hub 2, and the two ends of the central shaft 1 are arranged There is an input wheel 11, and a first overrunning clutch 12 is arranged between the input wheel 11 and the central shaft 1. In this embodiment, the input wheel 11 and the first overrunning clutch 12 form an assembly, and the central shaft 1 is a power input part, the hub 2 is a power output part, and the transmission mechanism includes two sets of planetary transmissions (the first planetary transmission 3 and the second planetary transmission 4) and two sets of automatic centrifugal shifting mechanisms (the first automatic centrifugal Shift mechanism 5 and the second automatic centrifugal shift mechanism 6).

[0025] The first planetary transmission 3 and the second p...

Embodiment 2

[0031] The rest of the structure of the straight-line pedaling single-wheel direct-drive ring gear fixed gear transmission in this embodiment is the same as that of the straight-line pedaling single-wheel direct-drive transmission in Embodiment 1, the difference is that in Embodiment 1, the central shaft The second ring gear is fixedly connected, and in Embodiment 2, the central shaft is fixedly connected with the second planet carrier.

[0032] The working principle of the straight-line stepping single-wheel direct-drive ring gear center wheel fixed transmission in this embodiment is as follows: the straight-line stepping single-wheel direct drive ring gear center wheel fixed transmission in this embodiment realizes three-stage speed change in total. The first step in this embodiment The second overrunning clutch is in the normally open state, that is, the first planetary carrier and the wheel hub are always in the meshing state. In low gear, the power is input from the centra...

Abstract

The invention discloses a liner treading single-wheel direct-drive tooth ring center wheel fixing transmission. The liner treading single-wheel direct-drive tooth ring center wheel fixing transmission includes a central shaft, input wheels, a wheel hub, and a transmission mechanism; the transmission mechanism includes a first planetary transmission, a second planetary transmission, a first automatic centrifugal shifting mechanism and a second automatic centrifugal shifting mechanism; the first planetary transmission includes a first planetary carrier, a first planetary wheel, a first tooth ring, and a first central wheel; an overrun clutch is arranged between the first planetary carrier and the wheel hub; the second planetary transmission includes a second planetary carrier, a second planetary wheel, a second tooth ring, and a second central wheel; the second central wheel is fixedly connected to a frame; the central shaft is fixedly connected to the second planetary carrier or the second tooth ring; the first automatic centrifugal shifting mechanism is arranged between the wheel hub and the second planetary carrier; the second automatic centrifugal shifting mechanism is arranged between the wheel hub and the second tooth ring; and in this way, the demand for the treading frequency is lowered at a medium-high speed.

Description

[0001] 【Technical field】 [0002] The invention relates to the technical field of bicycles, in particular to a straight-line pedal single-wheel direct drive ring gear center wheel fixed transmission. [0003] 【Background technique】 [0004] Bicycle transmissions are divided into two types: internal transmissions and external transmissions. The external transmission uses an open chain mechanism as the transmission system. By switching the shifter installed in front of the bicycle, the chain is changed to different flywheels to achieve different chain transmission ratios. Since the external derailleur is exposed, it is relatively easy to rust and is easily disturbed by external forces, so regular maintenance is often required. The internal derailleur mainly uses a planetary gear mechanism as the main transmission body, which is sealed inside the hub and passed through multiple layers of special sealing materials. Protection, so rainwater, dust, grease, etc. cannot enter, so there...
