Description

LINEAR DRIVING APPARATUS {LINEAR DRIVING APPARATUS}

Conventional bicycles are mostly driven by the circular motion of the crank pedal. However, only a small part of the 360 ° rotation of the crank is used to propel the bike, while the rest is consumed during the rotational movement. Rotary crank pedals are inadequate for converting a generally linear drive force applied by the occupant into a drive torque in a uniform and effective manner. Therefore, the occupant consumes excessive energy and easily feels tired. Since the pedal stroke of the circular crank pedal is not adjustable and requires a full turn of the crank pedal to drive a normal bicycle, the occupant's leg and stroke pattern may not fit well with the circular motion of the crank pedal.

A lever-propelled bicycle propelled by a lever that performs arcuate motion in the vertical direction has been proposed, but the mechanisms used to transfer the kinetic energy of the lever to the driving wheels have not been satisfactory. Many of these problem solutions were insufficient to provide a true linear drive mechanism, so 100% stroke efficiency could not be expected. In addition, the above solutions fail to provide a mechanism that enables the occupant to drive a vehicle through the front and rear stroke.

Therefore, it is desired from the position of bicycle enthusiasts and bicycle manufacturers to be able to drive the bicycle through the forward and backward strokes of the pedal, as well as the appearance of a linear drive system with true linear driving capability.

Applicable to all vehicles with two, three, four or more vehicles.

In one embodiment, the frame 102 may be made of suitable rigid materials well known in the bicycle art, such as aluminum or steel or their alloys, or glass or graphite fibers. One example of the frame 102 is a front bearing or fork tube 118, in which the front fork assembly 120 is rotatably fitted. The front fork assembly 120 includes a journal or steerer rotatably mounted within the fork tube 118 at its upper end. Front wheel 122 is rotatably mounted to the lower end of front fork assembly 120 in the same position as front axle 124. Two handlebars 126 rotate the front fork assembly 120 and the front wheel 122 about the axis of the fork tube 118 to steer the ride 100. Attached to the top of the The frame 102 includes one or more downward tube members, such as downward tubes 128, which at their rear ends provide wheel mounts 130 for mounting the rear wheel axle and rear wheel 104.

The frame 102 includes a seat 132 for comfortably supporting the occupant. Seat 132 is preferably a cushion material is built-in and can be easily adjusted according to the occupant. The seat 132 may be mounted to the front of the rear wheel 104 as shown, or may be located on top of the wheels as is well known in the art. The linear tracks 107 are mounted at appropriate locations, such as on both sides of the front portion 109 of the frame 102. Linear tracks 107 guide the left and right pedals 105A, 105B in a linear motion. The connection between the pedals 105A, 105B and the linear tracks 107 will be described in detail later with reference to FIGS. 2 and 3. In the embodiment of the invention shown in FIG. 1, the linear tracks 107 are maintained in a generally horizontal position with respect to the ground. However, other locations may also be considered, as described later in connection with FIG. 5.

An elongate flexible linkage 116 is connected to the left pedal 105A at the first end 117A and to the right pedal 105B at the second end 117B. In one embodiment of the present invention, the link mechanism 116 is routed to pass around the first link pulley 134 and the second link pulley 136. The first and second link pulleys 134, 136 are disposed on the first and second sides of the front end of the frame 102, respectively. In one embodiment of the invention, the first and second link pulleys 134, 136 may be replaced with a single pulley. The link mechanism 116 may be a belt, a chain or a cable. In addition, when the link mechanism 116 is a belt, the belt may be cogged. It is preferable to use a cable as the link mechanism.

The power transmitter 110 serves to transfer power from the pedals 105A and 105B to the drive wheel. It is preferable to use a belt, a chain (such as a roller chain) or a cable as the power transmitter 110. As the belt, any kind of power that can transmit power can be used, including a "V" belt and a cogged belt such as a belt material generally used as a timing chain of an automobile. The power transmitter 110 includes a drive portion and two pedal connection portions 112, 114. In the pedal connection portions 112, 114, the power transmitter 110 is mounted to enable a straight reciprocating motion with respect to the frame 102. The drive portion and the two or more pedal connection portions 112, 114 may be other portions of a single belt or two or more belts connected to the pedals 105A, 105B, respectively. In one embodiment of the invention, the two pedal connection portions 112, 114 are located in proximity to the first and second ends 138, 140 of the power transmitter 110, respectively. The power transmitter 110 extends from the left pedal 105A to the pulley 142 located proximate to the fork tube 118 and then across the pulley 142 is located below the seat 132. 144). The pulley 144 guides the power transmitter 110 around the first rotary driver 106 rotatably mounted to the wheel mount 130. The power transmitter 110 extends from the first rotary driver 106 around the pulley 145 which is located centrally just in front of the rear wheel 104 along the frame axis. Pulley 145 is used to guide power transmitter 110 to extend around rear wheel 104. The power transmitter 110 extends from the pulley 145 around the second rotary driver 108 on the second side of the ride. Like the first rotary driver 106, the second rotary driver 108 is rotatably mounted to the wheel mounting unit 130. Each of the first and second rotary drivers 106, 108 is rotatably engaged by a drive portion 111 of the power transmitter 110. The power transmitter 110 extends from the second rotary driver 108 to the pulley 146 located on one side of the frame 102 under the seat 132 opposite the pulley 144. The power transmitter 110 also extends to a pulley 148 located on one side of the frame 102 so as to face the pulley 142. The power transmitter 110 is then connected to a right pedal 105B positioned proximate to the second end 140 of the power transmitter 110. The power transmitter 110 and the link mechanism 116 form a closed loop. The power transmitter 110 and the link mechanism 116 may be separate or may be composed of a single member.

In addition, the number and location of the pulleys used to guide the power transmitter 110 may be varied. For example, depending on the type of frame 102 of the ride vehicle 100, other pulley structures may be used to route the power transmitter 110 to cross other components of the ride vehicle 100. 4, 5, 6, 8 and 11 are shown different types of pulleys, these pulleys are merely exemplary and are not intended to limit the scope of the present invention.

The first rotary driver 106 and the second rotary driver 108 may each include a pulley or sprocket rotatably mounted relative to the frame 102. The first and second rotary drivers 106, 108 are engaged with the rear wheel 104, respectively. In one embodiment of the present invention, the first rotary driver 106 and the second rotary driver 108 each comprise a one-way clutch that rotatably couples the corresponding rotary driver to the rear wheel 104.

It is configured to engage (i.e., transmit power) when the 110 is moved along a second direction opposite the first direction. The power transmitter 110 is configured to activate or engage the second rotary driver 108 while causing the link mechanism 116 to move the right pedal 105B forward by the rearward movement of the left pedal 105A. The pedals 105A and 105B are connected to drive the first and second rotary drivers 106 and 108. Similarly, when the right pedal 105B is moved rearward, the first rotary driver 106 is rotated or activated, and the link mechanism 116 moves the left pedal 105A forward. The activation direction of the first rotary driver 106 and the second rotary driver 108 is engaged by the rearward movement of the right pedal 105B and the second rotary driver 108 is engaged by the rearward movement of the left pedal 105A. It can be seen that the first rotational drive 106 may be switched to engage.

If desired, the first rotary driver 106 and the second rotary driver 108 are coupled to the power transmission 110, such as sprocket teeth or cogs that engage the roller chain or cogged belt. It may have teeth to engage.

FIG. 2 is a rear view of the right pedal 105B shown in FIG. 1. 3 is a plan view of the pedal assembly shown in FIG. Although the connection relationship between the right pedal 105B and the frame 102 is described in detail with reference to FIG. 2, the same connection relationship also applies to the left pedal 105A and the frame 102.

Those skilled in the art will appreciate that the illustrated pedal and track mechanisms are used for illustrative purposes only and that various mechanical equivalents and variations thereof may be used. In the illustrated embodiment, the right pedal 105B may be attached to one of the linear tracks 107 by multiple rollers 202A, 202B, 202C. Each linear track 107 may provide two guide rails 214, 216 for supporting multiple rollers 202A, 202B, 202C (see FIG. 2). In another embodiment of the present invention, each linear track 107 houses four rollers. However, it will be appreciated that a smaller or larger number of rollers may be used to engage the respective pedals 105A, 105B to the linear tracks 107. Right pedal 105B is mounted on two pillars 204 and 206. The two pillars 204, 206 are rotatably connected to the pedal support member 208 and extend perpendicular to the surface of the pedal support member 208 spaced apart from the frame 102. Pedal support member 208 has one or more openings (not shown) for receiving roller bolts 210A, 210B, 210C. Roller bolts 210A, 210B and 210C connect the pedal support member 208 to one of the multiple rollers 202A, 202B and 202C, respectively.

The second end 117B of the link mechanism 116 may be connected to the pedal support member 208. As noted above, the link mechanism 116 causes the other pedal to move in the opposite direction when one of the two pedals 105A, 105B moves in the first direction. The power transmitter 110 is also connected to the rear of the pedal support member 208 (see FIG. 3). In one embodiment, the pedals 105A, 105B may use toe clips or standard clipless instruments (not shown), where standard clipless instruments are used. The occupant's standard cycling shoes snap into the pedals 105A, 105B. 2 and 3 show a pattern in which each of the link pulleys 134, 136 is rotatably mounted to the frame 102 by the pulley bolt 222 and the pulley nut 224.

Next, another embodiment of the present invention will be described with reference to FIG. 4. For the sake of clarity of explanation, only differences between the embodiments of the present invention shown in FIGS. 1 and 4 will be described. The ride mechanism 100 includes a chest support 402 for supporting the chest of the occupant (not shown). The chestrest 402 may have a contour suitable for supporting the occupant's chest.

Similar to the case of the embodiment shown in FIG. 1, the ride 100 has linear tracks 107 positioned at an angle of approximately 45 ° with respect to the ground.

Respective ends 138, 140 of the power transmitter 110 are connected to pedals 105A, 105B, respectively. The power transmitter 110 extends from the pedal 105A to the pulley 142. The pulley 142 guides the power transmitter 110 downward toward the first rotational drive 302 mounted on the bottom end of the rear wheel support member 404. The power transmitter 110 extends upward from the first rotary driver 302 and extends around the pulley 306 mounted on the rear side of the rear wheel support member 404. The power transmitter 110 then extends downwardly towards the second rotary driver 308, which is mounted on the bottom end of the rear wheel support member 404. The power transmitter 110 extends around the pulley 148 from the second rotary driver 308 and is finally connected to the right pedal 105B.

In one embodiment of the present invention, the first rotary driver 302 and the second rotary driver 308 each comprise a one-way clutch. One-way clutches may be implemented using roller clutches, pawls and ratchets, freewheels, or other types of conventional drive mechanisms that transmit power in one direction of rotation and no power in the other direction of rotation. .

When the power transmitter 110 (see FIG. 4) moves in the first direction, the first rotary driver 302 is engaged to transfer the power to drive the rear wheel 104 in all directions. When the power transmitter 110 moves in the second direction, the second rotary driver 308 is engaged to drive the rear wheel 104 in all directions. Further, each of the pedals 105A, 105B is connected to each other such that movement in one direction of one of the pedals 105A, 105B causes movement in the opposite direction of the other pedal.

Referring to Fig. 5, a scooter employing the linear tracks 107 of the present invention is shown. The linear tracks 107 are mounted on the frame 102 to be positioned generally perpendicular to the ground. For the sake of clarity, only the differences between the embodiments of the present invention shown in FIGS. 5 and 1 will be described. The ride mechanism 100 of FIG. 5 does not have a separate seat because a passenger pushes the ride mechanism 100 in an upright position. As with the embodiment of the present invention shown in FIG. 1, the respective ends 138, 140 of the power transmitter 110 are connected to the pedals 105A, 105B, respectively.

Referring again to FIG. 5, the power transmitter 110 extends from the pedal 105A to the pulley 142. The pulley 142 guides the power transmission 110 downwardly toward the first rotary driver 302 mounted on the bottom end of the rear wheel support member 404. The power transmitter 110 extends upwardly from the first rotary driver 302 and extends around the pulley 306 mounted to the front side of the rear wheel support member 404. The power transmitter 110 then extends downwardly towards the second rotary driver 308, which is mounted on the bottom end of the rear wheel support member 404. The power transmitter 110 extends around the pulley 148 from the second rotary driver 308 and is finally connected to the right pedal 105B.

In one embodiment of the present invention, the handlebar 126 is configured to adjust to a comfortable height for the occupant while stepping on the left and right pedals 105A, 105B. In another embodiment of the present invention, it can be seen that the linear tracks 107 can be mounted to form an angle of 0 ° to 90 ° with respect to the ground.

Figure 6 shows another embodiment of the present invention using the front wheel drive method. Like the embodiment shown in FIG. 1, the ride 100 is mounted on the frame 102 in a generally horizontal position. For convenience of explanation, only differences between the embodiments of the present invention shown in FIGS. 6 and 1 will be described.

As in the embodiment of the present invention shown in FIG. 1, the ends 138, 140 of the power transmitter 110 are connected to the pedals 105A, 105B, respectively. The power transmitter 110 extends from the pedal 105A to the pulley 142. Pulley 142 guides power transmitter 110 downwardly toward first rotational drive 302 mounted on the bottom end of front fork assembly 120. The power transmitter 110 extends upward from the first rotary driver 302 and extends around the pulley 306 mounted on the front side of the fork tube 118. The power transmitter 110 then extends downwardly towards the second rotary driver 308, which is mounted on the bottom end of the front fork assembly 120. The power transmitter 110 extends from the second rotary driver 308 around the pulley 148 and is finally connected to the right pedal 105B.

In one embodiment of the present invention, the first rotary driver 302 and the second rotary driver 308 each comprise a one-way clutch. One-way clutches may be implemented using roller clutches, pawls and ratchets, freewheels, or other types of conventional drive mechanisms that transmit power in one direction of rotation and no power in the other direction of rotation. .

As in the operation of the embodiment shown in FIG. 1, the movement of the power transmitter 110 in the first direction engages the first rotary driver 302, ie causes the first rotary driver 302 to power up. The front wheel 122 is driven in all directions so as to transmit. Movement of the power transmitter 110 in the second direction causes the second rotary driver 308 to transmit power to drive the front wheel 122 in all directions. Further, each of the pedals 105A, 105B is connected to each other such that movement in one direction of one of the pedals 105A, 105B causes movement in the opposite direction of the other pedal.

FIG. 7 is a front view of the spring loaded pulley 306 shown in FIG. The spring loaded pulley 306 includes a pulley 702, a pulley base 704 having a narrow and long opening, and a spring 706. The spring 706 is connected at its upper end to the fork tube 118 by a fixing device 708 such as a screw. At the end opposite to the connection to the fork tube 118, the spring 706 is connected to the pulley base 704.

The spring loaded pulley 306 provides slack to the power transmitter 110 when the front fork assembly 120 is rotated left or right. The pulley base 704 is fixed to the fork tube 118 by a second fixing device 710.

Referring to FIG. 8, there is shown another embodiment of the present invention employing a rotary driver 800 to drive the wheel forward when the power transmitter 110 moves. As with the embodiment shown in FIG. 1, the ride 100 has linear tracks 107 mounted on the frame 102 in a generally horizontal direction (as described above, other than the horizontal position). Is also possible).

Power transmitter 110 extends from pulley 142 to pulley 802 maintained in a horizontal position proximate to the rear end of seat 132. The power transmitter 110 then extends from the pulley 802 around the rotary driver 800 which is rotatably mounted on the wheel mount 130. The power transmitter 110 then extends to a pulley 804 mounted to the frame 102 in proximity to the bottom surface of the seat 132. The power transmitter 110 continues to extend from the pulley 804 toward the pulley 148.

The operation of the left and right pedals 105A, 105B on the linear tracks 107 is the same as in the embodiment shown in FIG. Movement of the power transmitter 110 in each of the first and second directions causes the rotary driver to drive the rear wheel 104 in all directions.

Rotational driver 800 may be implemented using a variety of mechanisms, such as multiple roller clutches, conventional freewheels, or a pawl and ratchet system, having a rotational drive comprising two one-way roller clutches in connection with FIGS. 9 and 10. The embodiment will be described in detail. 9 and 10, details of the rotation driver 800 are shown. 9 shows a cross-sectional view of the rotary driver 800 and FIG. 10 shows a side view of the rotary driver 800.

The rotary driver 800 includes a pulley 902 engaged by the power transmitter 110. The rotary driver 800 includes two drive mechanisms for driving the wheel 104 (see FIG. 8) when the power transmitter 110 moves in the first direction 908 and the second direction 910. . It can be seen that the first direction 908 generally points towards the rear portion of the ride vehicle 100 and the second direction 910 generally points towards the front portion of the ride vehicle 100.

The outer side of the pulley 902 is coupled to the first one-way roller clutch 912. When the pulley 902 is rotated in the second direction 910, the first one-way roller clutch 912 does not transmit power away from the wheel 104 (see FIG. 8). However, when the pulley 902 is rotated in the first direction 908, the pulley 902 engages (attaches) or activates the first one-way roller clutch 912. When activated, the first one-way roller clutch 912 is engaged with a ring gear 914 having a number of teeth on its inner circumferential surface. A ring gear 914 is located adjacent to an inner surface of the first one-way roller clutch 912 opposite from the pulley 902. Ring gear 914 is coupled with three large planetary gears 916A, 916B, 916C. Each of the large planetary gears 916A, 916B, 916C is installed at equal intervals on the inner surface of the ring gear 914 opposite to the pulley 902.

Each of the large planetary gears 916A, 916B, 916C is fixedly and coaxially attached to three small planetary gears 918A, 918B, 918C. Large planetary gear 916A and small planetary gear 918A are rotatably coupled to planetary gear axle 920A. Similarly, large planetary gear 916B and small planetary gear 918B are rotatably coupled to planetary gear axle 920B. In addition, the large planetary gear 916C and the small planetary gear 918C are rotatably coupled to the planetary gear axle 920C. Although only three large planetary gears 916A, 916B, 916C and three small planetary gears 918A, 918B, 918C are shown in the figure, the rotary driver 800 has a larger or smaller number of large formations. And small planetary gears.

The planetary gear axles 920A, 920B, 920C extend to make an angle of 90 ° with respect to the surface of the support disk 922, respectively. The support disk 922 is fixed to the axle 926 or frame 102 in a non-rotatable state.

Each of the three small planetary gears 918A, 918B, 918C meshes with the sun gear 928. The sun gear 928 is fixedly attached to the rotating member 929 that drives the wheel 104 (see FIG. 8). On the inner surface of the rotating member 929 opposite the sun gear 928 a plurality of ball bearings 930 are arranged to facilitate the movement of the rotating member 929.

On the side of the rotary driver 104 proximate the wheel 104, a second one-way roller clutch 940 is coupled to the inner surface of the pulley 902. The second one-way roller clutch 940 is configured to transmit power by the movement of the pulley 902 when the pulley 902 moves in the second direction 910. The second one-way roller clutch 940 is engaged at the outer edge of the annular connecting member 942. On the inner surface of the connecting member 942 opposite the connecting portion to the second one-way roller clutch 940, the connecting member 942 is fixedly attached to the rotating member 929.

As can be seen most clearly from FIG. 10, when the power train 110 moves in the first direction 908, the power train 110 drives the pulley 902 in the same direction and thus pulley 902. Cause counterclockwise movement. Counterclockwise movement of the pulley 902 engages the first roller clutch 912 to be moved counterclockwise. In addition, the counterclockwise movement of the first one-way roller clutch 912 engages and rotates the large planetary gears 916A, 916B and 916C and the small planetary gears 918A, 918B and 918C in the counterclockwise direction. Rotation of each of the miniature planetary gears 918A, 918B, 918C engages the sun gear 928 and causes it to rotate clockwise. As a result, the sun gear 928 engages the rotating member 929 to drive the wheel 104 (see FIG. 8) forward.

10, when the power transmitter 110 is moved in the second direction 910, the second one-way roller clutch 940 is engaged and rotates clockwise. The second one-way roller clutch 940 engages the connecting member 942 to rotate in a clockwise direction. Clockwise rotation of the connecting member 942 also causes the rotating member 929 to be driven clockwise. Therefore, the wheel 104 (see FIG. 8) is driven forward as the power transmitter 110 rotates in the first and second directions 908, 910.

Figure 11 shows another embodiment of the present invention employing a front wheel drive method. The power transmitter 110 extends from the first end 138 to the pulley 1100 connected to the first side of the vehicle 100 in proximity to the fork tube 118 and back of the front fork assembly 120. It extends to the pulley 1102 located on the side. Pulley 1102 guides power transmitter 110 to rotary drive 1104 mounted on the bottom end of front fork assembly 120. The rotary driver 1104 may be configured similarly to the rotary driver described with reference to FIGS. 9 and 10, or alternatively, other drive mechanisms may be used. The power transmitter 110 extends from the rotary driver 1104 to the pulley 1106 located on the front portion 109 of the frame 102 in proximity to the fork tube 118. The power transmitter 110 extends from the pulley 1106 to the right pedal 105B and is attached thereto.

The rotary driver 1104 transmits power to the front wheel 122 when the power transmitter 110 is moved in the first and second directions so that it is driven in all directions. Like the rotary driver 800 of FIG. 8, the rotary member 1104 may be implemented using two one-way roller clutches as described above with respect to FIGS. 9 and 10. In addition, the pulleys 1102 and 1106 may be configured as spring-loaded pulleys as shown in FIG.

As can be seen from the above description, the linear drive system of the present invention solves a number of problems common to the drive methods according to the prior art. First, the linear drive system of the present invention allows the occupant to apply power to the vehicle during the forward and backward strokes of the vehicle. In addition, the stroke movement of the occupant is almost 100% efficient. This is in contrast to other types of rotary drive systems that can achieve only 30-50% efficiency. Further, by using the linear drive mechanism of the present invention, it becomes possible to adjust the length of the stroke. For example, a rider can make a shorter and faster stroke when climbing a hill and a longer stroke when descending a hill. By using a large leverage that can be realized in all embodiments, it is possible to obtain a high speed vehicle with excellent acceleration performance. The linear drive system of the present invention allows more leg muscles to be used than with rotary drives, thereby activating hamstrings and gluteals and further improving the speed and acceleration of the vehicle. Thus, the linear drive action of the present invention results in more comfort and less fatigue than conventional rotary actuation systems.

In the above, the present invention has been described based on several exemplary embodiments, but those skilled in the art will be able to implement the invention in various forms within the scope of the claims. Accordingly, the scope of the present invention is to be determined by the appended claims rather than the foregoing description. In addition, all changes belonging to the literary and equivalent scope of the claims should not be considered beyond the scope of the present invention.
