Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a two-

The present invention relates to a bicycle or motorcycle cushion type wheel structure, and more particularly, to a bicycle or motorcycle cushion type wheel structure, and more particularly, to a bicycle or a motorcycle which is capable of assuring a stable running on roads such as snow roads, ice roads, mountain roads, stairs, And at the same time, can efficiently absorb and cushion impact and vibration.

Generally, a bicycle or a motorcycle is a means of transporting people and goods using manpower or engine power.

Such a two-wheeler has a structure in which a front wheel and a rear wheel arranged in a line are coupled to a frame. The front wheel is responsible for the steering function of the two-wheeled vehicle so that the two-wheeled vehicle can proceed in a desired direction by the user's operation. The rear wheel is rotated by the power or attraction of the engine to perform the driving function of the two-wheeled vehicle.

Since the entire two-wheeled vehicle having such a configuration is inclined at an angle from the horizontal plane toward the steering direction during steering, the rear wheel ideally has a point contact with the ground in consideration of the stability of the vehicle when the vehicle is tilted, (Hereinafter, "face contact" is also referred to as "point contact" for convenience of explanation).

Accordingly, the front wheel and the rear wheel of the two-wheeled vehicle are in point contact with the ground, and are moved by the frictional force at the point-contact point.

On the other hand, since the surface friction coefficient of the road on which snow is accumulated or the ice sheet is small, the running of the motorcycle becomes dangerous.

In other words, when snow is piled up on the road surface, the driving force of the rear wheel is not normally transmitted due to the small surface friction coefficient due to eyes in bicycles and motorcycles which are two-wheeled vehicles, and the front and rear wheels slip along the eyes even when stopped, There arises a problem that the safe driving can not be guaranteed because it is lengthened.

Therefore, the proposed conventional registered utility model 20-0441376 (registered date 2008.8.6) of the snow chain for a two-wheeled vehicle is coupled to the wheel 20 of the two-wheeled vehicle as shown in Figs. 1 and 2 to provide a friction force necessary for running The tire according to claim 1 or 2, wherein the tire (12) comprises a friction band portion which surrounds the outer periphery of the tire (12) constituting the wheel (20) The friction band includes a metal wire 140 having a plurality of wire wires wound thereon and a friction spring 150 coupled to the metal wire 140 along the outer circumference of the metal wire 140. [ .

However, the conventional snow chain 100 for a two-wheeled vehicle constructed as described above is mass-produced separately and mounted on a necessary wheel 20 so that the vehicle can stably travel without slipping on the road surface such as an eye or an ice sheet This structure is inconvenient and cumbersome to mount or separate a plurality of snow chains 100 at regular intervals along the circumference of the wheel 20, and is limitedly used in snowy roads and ice roads, There has been a problem in that it can not be used because there is a risk of breakage due to an impact on an extreme road surface such as a stairway.

In addition, since the conventional snow chain 100 does not have a function of absorbing and cushioning shocks and vibrations, shock and vibration are generated at the time of mounting, which causes a problem of significantly reducing the feeling of ride.

The object of the present invention is to solve the problems in view of the existing problems and to ensure stable running regardless of road surface such as snow road, ice road, mountain road, stairs, road surface, pavement road and unpaved road Which is capable of efficiently absorbing and cushion shocks and vibrations transmitted from the road surface by the wheels themselves, thereby enhancing ride comfort.

According to an aspect of the present invention, there is provided a two-wheel vehicle cushion-type wheel assembly comprising: a hub of a front wheel and a rear wheel; a plurality of fixed and fixed wheels coupled to the outer circumference of the hub in a radial direction, A plurality of fixed spokes, a ring-shaped rim portion coupled with an outer end of the plurality of fixed spokes, and a ring-shaped rim portion extending radially from the outer peripheral surface of the rim portion at a predetermined interval in a rotational direction, A plurality of cushion spokes fixed to be arranged in two rows in a zigzag manner and spaced apart from each other, a plurality of ground portions which are respectively fastened to the ends of the cushion spokes so as to be brought into contact with the road surface so as to increase braking force, The left and right sides are wrapped to a predetermined length of the plurality of buffer spokes, That the cover plate consists of a pair of left and right connecting standing features.

In another embodiment, the plurality of cushion spokes of the present invention is configured to be inclined forward from the center of rotation of the rim toward the ground, and the angle is 5-15 degrees.

In another embodiment, the plurality of cushion spokes of the present invention are characterized by being made of any one of hydraulic pressure, gas, and spring.

In another embodiment, the plurality of cushion spokes of the present invention includes a cylinder having a lower portion fixedly secured to the outer peripheral surface of the first rim portion at a predetermined interval in the rotating direction, and a lower end portion of the cylinder, And the other end of the piston is fixed to the plurality of ground portions and is moved up and down by a buffering force.

In another embodiment, the plurality of ground portions of the present invention are characterized by being made of any one selected from the group consisting of tire rubber or spike metal for ice sheets.

In another embodiment, the plurality of ground portions of the present invention are configured to be engaged or separated, respectively, with the outer ends of the plurality of cushion spoke portions via bolts passing through the vertical center thereof.

The two-wheeler cushion-type wheel structure according to the present invention is characterized in that a plurality of shock-absorbing spokes using cylinders and pistons are arranged on the outer circumferential surface of the rim portion in two rows in a staggered manner in the width direction of the rim portion while being radially extended at regular intervals along the rotational direction And a grounding portion serving as a tire or a spike is interchangeably coupled to the ends of a plurality of pistons. Therefore, it is possible to prevent the occurrence of a road surface such as snow road, ice road, mountain road, stairs, It is possible to ensure stable running irrespective of the vehicle speed, and to effectively absorb and cushion impact and vibration transmitted from the road surface, thereby enhancing ride comfort.

Hereinafter, embodiments of the present invention will be described in detail with reference to FIGS. 3 to 6. FIG.

The two-wheeler cushion-type wheel structure according to the present invention includes a hub 50 of front and rear wheels 40 and 42, and a plurality of fixed and fixed wheels 50 and 50 which are coupled to the outer circumferential surface of the hub 50 in a radial direction, A ring-shaped rim 70 coupled with an outer end of the plurality of stationary spokes 80; a radially extending rim 70 at a predetermined interval in the rotational direction on the outer circumferential surface of the rim 70; A plurality of buffer spokes 80 fixed to the outer circumferential surface of the rim 70 at predetermined intervals in a zigzag fashion so as to be spaced apart from each other in the width direction, A plurality of grounding portions 90 fastened to each other so as to be in contact with the road surface so as to increase the braking force and a left and right side surface covering a predetermined length of the plurality of buffering spoke portions 80 on the outer circumferential surface of the rim portion 70 Connecting And a pair of left and right cover plates 100.

That is, the plurality of buffer spokes 80 are configured to be inclined forward from the center of rotation of the rim 70 toward the ground portion 90, and the angle is 5 to 15 degrees .

The plurality of cushion spoke portions 80 are made of any one selected from the group consisting of hydraulic pressure, gas, and spring. The plurality of cushion spoke portions 80 are fixed to the outer circumferential surface of the first rim portion 70 at predetermined intervals in the rotating direction, And a piston 84 having one end connected to the lower portion of the cylinder 82 and the other end fixed to the plurality of the grounding portions 90 so as to move up and down by a buffering force.

The springs 90 of the bolts 92 are vertically centered to penetrate the pistons 84 of the cushion spokes 80. In this case, And a through hole 90a is formed to be engaged with or separated from the screw hole 84a formed at the outer end.

The pair of left and right cover plates 100 are formed in a thin disc shape made of any one selected from synthetic resin or metal. A circular hole 102 is formed at the center thereof to fix and fix the outer peripheral surface of the rim portion 70, And an end thereof abuts against the outer end of the cylinder 82 of the plurality of cushion spokes 80 to be fixed.

Next, the operation and effect of the thus-configured motorcycle cushion-shaped wheel structure of the present invention will be described.

Wheeled cushioning wheel structure of the present invention is characterized in that a plurality of cushion spokes 80 using a cylinder 82 and a piston 84 are radially extended on the outer circumferential surface of the rim 70 at a predetermined interval in the rotational direction, And the ground portions 90, which serve as tires or spikes, are fixed to the ends of the plurality of pistons 84, respectively, It is possible to steadily travel without regard to severe road surfaces such as mountain roads and stairs, road surface conditions such as pavement roads and unpaved roads, as well as efficiently absorb shocks and vibrations,

That is, when the occupant sits on the saddle, the ground portion 90 of the front and rear wheels 40, 42 abutting the road surface due to the weight of the occupant is pushed toward the rim portion 70 from the ground portion 90, Thereby compressing the cushioning spoke portion 80.

When the vehicle travels in this state, the grounding portion 90 pushed against the road surface due to the weight of the passenger is moved outwardly by the expansion force of the buffering spoke portion 80 and returned, The shock and vibration are absorbed and cushioned by the shock absorbing spoke portion 80 connected to the ground portion 90 abutting the road surface.

At this time, the plurality of grounding portions 90 are arranged one by one for each piston 84 of the cushioning spokes 80 radially extending from the rim portion 70, and are arranged in two rows in a staggered manner so as to be shifted from each other in the width direction, The tire or the spike so as not to break the road, such as eye road, ice road, mountain road, stairs and roads, such as pavement roads and unpaved roads, etc., At the same time, stable driving is induced.

The piston 84 of the cushion spoke portion 80 connected to the plurality of ground portions 90 is vertically cushioned into the cylinder 82 in response to impact and vibration transmitted from the road surface, As shown in FIG.

A plurality of cushion spokes 80 connecting the rim 70 and the plurality of grounding portions 90 are arranged at an angle of 5-15 degrees from the center of rotation of the rim portion 70 toward the grounding portion 90, The buffering spoke portion 80 can immediately react with the braking pressure of the grounding portion 90 that contacts the road surface during braking while the vehicle is running, and the vertical movement of the buffering spoke portion 80 can be smoothly .

In particular, since the plurality of ground portions 90 are divided into small volumes and are connected to the point structure so as not to interrupt the rotational driving force as in the existing orbital line of the existing tires, they form the same tread and mountain as the existing tire tread surface upon contact with the road surface, It is minimized.

In addition, since a plurality of ground portions 90 are point-contacted when they come into contact with the road surface, their buffer forces are different from each other depending on the road surface condition, so that the grounding force is further increased than when existing tires are in surface contact. This makes it possible to travel more reliably on extreme road surfaces such as the ground.

The plurality of grounding portions 90 can be coupled to or separated from the ends of the piston 84 of the shock absorbing spokes 80 through the bolts 92. The grounding portions 90 serve as tires or spikes It can be selected from rubber or metal.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
