Embodiment 1

[0032] like Figure 4 Shown, a kind of rear wheel drive part, it is installed on the vehicle frame 1, and is used for driving rear wheel 14 to rotate on vehicle frame 1, and it comprises:

[0033] Gear transmission mechanism 8, described gear transmission mechanism 8 comprises driving ring gear 81, planetary gear 82 and driven wheel 83, and described driven gear 83 is coaxially connected with described rear wheel 14, and described planetary gear 82 is arranged on the driving gear between the ring gear 81 and the driven wheel 83, and the planetary gears 82 mesh with the driving ring gear 81 and the driven wheel 83 respectively;

[0034] The driving mechanism 7 is connected to the driving gear 81 so that the driving gear 81 can rotate around the axle center of the driven wheel 83 by actuating the driving mechanism 7 .

[0035] like Figure 4 As shown, the drive mechanism 7 includes a first crank 71, a second crank 72 and a connecting rod 73, one end of the second crank 72 is h...

Embodiment 2

[0040] like Figure 4 Shown, a kind of rear wheel drive device, it comprises the rear wheel drive part in two embodiment one; Wherein,

[0041] The two rear wheel drive components act on the two ends of the rear wheel 14 respectively, the connecting part between the first crank 71 of one rear wheel drive component and the corresponding driving ring gear 81 and the first crank of the other rear wheel drive component 71 and the corresponding connecting portion of the driving ring gear 81 are arranged symmetrically with respect to the wheel axis center of the driving ring gear 81, and the first cranks 71 of the two rear wheel drive components are arranged in line, and the second cranks 72 of the two rear wheel drive components Collinear arrangement, the connecting rods 73 of the two rear wheel drive components are arranged in parallel.

Embodiment 3

[0043] like Figure 1-8 Shown, a kind of chainless pedal bicycle, it comprises:

[0044] frame 1;

[0045] Rear wheel 14, described rear wheel 14 is rotatably supported on the rear portion of vehicle frame 1; Specifically, the rear portion of described vehicle frame 1 is rotatably supported with rear wheel axle 15 through rear wheel bearing 16, and described rear The wheel 14 is installed on the rear axle 15 through a key connection; the driven wheel 83 is installed on the rear axle 15 with interference fit;

[0046]The rear wheel driving device in the second embodiment, the rear wheel driving device is connected with the rear wheel 14, so that the rear wheel driving device drives the rear wheel 14 to rotate on the vehicle frame 1; specifically, the vehicle frame 1 has a rear wheel The wheel fork bracket, the driving mechanism 7 of the two rear wheel drive components are respectively located on both sides of the two rear wheel fork bracket;

[0047] Front wheels 4 are mount...

Abstract

The invention discloses a rear wheel drive unit, a rear wheel drive device and a chainless treadle bicycle applying the same. The rear wheel drive unit is mounted on the frame and used for driving a rear wheel to rotate on the frame, and the rear wheel drive unit comprises a gear transmission mechanism and a driving mechanism; the gear transmission mechanism comprises a driving gear ring, a planetary wheel and a driven wheel, the driven wheel is coaxially connected with the rear wheel, and the planetary wheel is arranged between the driving gear ring and the driven wheel and respectively meshed with the driving gear ring and the driven wheel; the driving mechanism is connected with the driving gear ring to enable driving gear ring to rotate around the wheel axis of the driven wheel by actuating on the driving mechanism. The rear wheel can be driven to move forward, the basic function of riding instead of walking can be realized, and the purposes of simple structure and bodybuilding and entertainment can be achieved.

Description

technical field [0001] The invention relates to a rear wheel drive component, a rear wheel drive device and a chainless pedal bicycle using the same, which belongs to the technical field of transportation means. Background technique [0002] At present, bicycles have become the most widely used means of transportation in people's daily life. Although bicycles are now replaced by various more advanced and efficient means of transportation, with the development of society and technology and the transformation of people's lifestyles , the bicycle has also changed from a traditional means of transportation to a tool for people's sports, fitness, and leisure, especially when the world is facing increasingly serious problems such as traffic congestion and air pollution. into people's field of vision. [0003] Traditional bicycles are mostly in the form of chain transmission, which transmits movement through chain transmission. Although it can achieve the purpose of transportation...
