Embodiment 1

[0017] In FIG. 2 , a central axis support 80 for fixing the central axis is installed on the rear frame 7 , the central axis 8 is installed on the central axis support 80 , and the rear frame 7 and the beam 1 are fixed.

[0018] The rear wheel 5 and the rear axle 6 are installed on the rear vehicle frame 7, and the rear wheel chain 21 is installed on the rear axle multi-stage speed change flywheel 61 on the rear axle 6 and the central axle fixed sprocket 82 on the central axle 8.

[0019] In Fig. 2 and Fig. 3, the right slide rail 10 and the left slide rail 10a are respectively installed on both sides of the beam 1, and the right slide block 17 and the left slide block 17a are put into respectively on the two slide rails, and on the two slide blocks The right foot support 18 and the left foot support 18a are installed respectively. Install a pair of elastic barriers on both sides of each slide rail to prevent the slider from derailing.

[0020] In Fig. 2, the right rear horiz...

Embodiment 2

[0032] Fig. 6 is Embodiment 2 of the present invention. Embodiment 2 is roughly the same as Embodiment 1, the only difference is:

[0033] In Fig. 6, embodiment 2 is no longer the same as embodiment 1, and the right rear sprocket 11, the right middle sprocket 12, the right front sprocket 13, the left rear sprocket 11a, the left sprocket are installed on both sides of the beam. Side middle sprocket 12a, left front sprocket 13a. Instead, install the right rear fixed pulley 31, the right left middle fixed pulley 32, the right right middle fixed pulley 33 and the right front fixed pulley respectively at the positions below the right slide rail 10 both sides and the middle on the crossbeam. 34. Respectively respectively install a fixed pulley at the left side of the crossbeam with the rear fixed pulley 31 on the right side, the middle fixed pulley 32 in the left side, the fixed pulley 33 in the right side right middle, the fixed pulley 34 symmetric positions in the right side res...

Abstract

A slide direct pedal bicycle is made up of the frame, ream, handlebar, the front fork, the front wheel, the back axis, the back wheel, the slide track, the driving chain, the middle axis and the transmission chain. The slide track is installed on the both sides of the beam, the two foot petals are installed on the slide mass of the slide track which do the linear motion on the slide track. The middle axis has two flywheel and fixed chain gear fixed on the axis skin. The flywheel is covered with the driving chain connected to the slide mass and the fixed chain gear is connected with the back flywheel by the chain. The frame is fixed with the beam according to the different gradient to form the backrest supine bicycle.

Description

technical field [0001] The invention relates to a slide rail straight-pedal bicycle in which the feet move in a straight line Background technique [0002] At present, traditional bicycles use the feet to make circular motions on the crank, which drives the crankset, chain, and flywheel to rotate forward, thereby driving the rear wheel to rotate. This type of bicycle saddle is all higher, and the comfortability of riding is not good enough. In addition, due to the high center of gravity, the safety is also poor when driving at high speeds. Although some recumbent bicycles have appeared in recent years, most still adopt the pedal mode of doing circular motion on the crank. Because the crankset and the crank are usually arranged at a higher place in front, the legs need to be raised when riding, and it is difficult and uncomfortable for the feet to make circular motions on the crank. [0003] The invention provides a linear motion slide rail direct pedal driving mode, and t...
