Problems solved by technology

[0003] One-way flywheel exercise bike (vertical exercise bike or horizontal exercise bike) because the inertia of the flywheel cannot be transmitted to the shaft, when the foot stops driving, it cannot drive the shaft and pedals to continue moving, so it is impossible to jump on it. Unable to make many fitness movements; when the two-way flywheel exercise bike (spinning bike) needs to stop immediately, the inertia will continue to drive the shaft and feet to move, and there is a risk of human injury
[0004] In addition, in order to realize the fitness of two kinds of exercise, the user needs two fitness equipment, which is not only inconvenient but also increases the cost of fitness

Embodiment 1

[0047] A one-way two-way flywheel, such as Figure 1-3 As shown, it includes a flywheel body 1, a central shaft 2, a coupling 3 and a supporting mechanism.

[0048] In this example, if figure 2 As shown, the left and right sides of the flywheel body 1 are provided with rolling bearings 101. In this embodiment, the rolling bearings 101 are deep groove ball bearings, but not limited thereto; the axis of the flywheel body 1 is embedded with a one-way bearing 102. The one-way bearing 102 in this embodiment is a one-way needle bearing, but it is not limited thereto.

[0049] The central shaft 2 is installed at the axis of the flywheel body 1 and passed through the rolling bearing 101 and the one-way bearing 102 . Both ends of the central shaft 2 are supported by the supporting mechanism.

[0050] In this embodiment, the support mechanism is composed of a left support plate 4-1 and a right support plate 4-2, and at least two connecting rods are passed between the left support pla...

Embodiment 2

[0058] A unidirectional and bidirectional flywheel adjustment system includes a shifting assembly, a brake assembly and the unidirectional and bidirectional flywheel in Embodiment 1.

[0059] Such as Figure 6-8 As shown, the shifting assembly includes: a spring fork 7 , an adjustment handle 8 , and a shifting cable 9 .

[0060] In this example, if Figure 7 and 8 As shown, the spring fork 7 is arranged on the shaft coupling 3 for moving the shaft coupling 3 . Such as Figure 4 As shown, the outer wall of the coupling 3 is provided with an annular slot 3-3, and the top end of the spring fork 7 is concavely provided with a U-shaped groove 7-1, and the arc of the U-shaped groove 7-1 is in line with The radians of the annular locking groove 3-3 match, so that the spring shift fork 7 can be clamped in the annular locking groove 3-3 through the U-shaped groove 7-1, as image 3 As shown, the bottom of the spring fork 7 is fixed to the left support plate 4-1 by bolts.

[0061] ...

Embodiment 3

[0075] This embodiment provides a single-direction flywheel adjustment system. The difference from Embodiment 2 is that the adjustment of the shift assembly and the brake assembly are set separately in this embodiment.

[0076] Specifically, the brake line is directly connected to the fixed seat 10-2, and the end of the brake line away from the brake pad 10 is connected to the brake handle, and the brake pad 10 is driven to rotate through the brake handle. At this time, the shift cable 9 can Set to a straight line, the tail end of the shifting cable 9 is connected to the adjustment handle 8, and the front end is connected to the spring fork 7, and the single and bi-directional mode of the flywheel is adjusted through the adjustment handle 8.

Abstract

The invention provides a single-direction flywheel and its adjustment system, which belong to the field of fitness equipment. The single-direction flywheel includes a flywheel body, a central shaft and a coupling. A one-way bearing is embedded in the center of the flywheel body, and the central shaft passes through the The one-way bearing is provided, and the coupling is movably sleeved on the central shaft to realize engagement and separation with the flywheel body. The single- and two-way flywheel adjustment system includes: a single- and two-way flywheel and a shifter assembly, the shifter assembly includes a spring fork, an adjustment handle and a shifter cable, the spring fork is set on the coupling, and the adjustment handle can be rotated to set; the shifter The pull wire is used to connect the spring fork with the adjustment handle, so as to control the loosening and tightening of the spring fork through the adjustment handle, and then drive the shaft coupling to move along the central axis. The present invention can realize the switching between the one-way mode and the two-way mode of the single-bidirectional flywheel through the adjustment system, that is, two exercise modes can be realized through one exercise bike, which is convenient to use and can reduce the cost.

Description

technical field [0001] The invention belongs to the field of fitness equipment, and in particular relates to a single- and two-way flywheel. In addition, the invention also relates to a single- and two-way flywheel adjustment system. Background technique [0002] Existing exercise bikes can be divided into vertical exercise bikes, recumbent exercise bikes and spinning bikes according to the different ways of exercise. Among them, the vertical exercise bike and the horizontal exercise bike use a one-way flywheel, that is, the flywheel can only turn in one direction. When the foot stops driving, the flywheel will still continue to rotate with inertia; the spinning bike uses a two-way flywheel. It can rotate in both positive and negative directions. When the foot stops driving, the flywheel will drive the foot to continue moving due to inertial rotation. [0003] One-way flywheel exercise bike (vertical exercise bike or horizontal exercise bike) because the inertia of the flyw...
