As shown in Fig. 1, the push-pull driving carriage includes a bottom plate 5, a push-pull rod 1 having a force arm fulcrum on the bottom plate 5, and a connecting mechanism 62. The front end of the bottom plate 5 includes a front wheel assembly 61 of the steering mechanism, and the rear end thereof includes a speed increasing gear mechanism 12 and a rear wheel assembly 63 of the one-way device 7; the upper end of the push-pull rod 1 is provided with a support 14, the arm support point is pivotally supported by the bottom plate 5 and connected to the steering mechanism for steering; wherein the handle 14 described later can be vertically connected to the push-pull rod 1 or directly push-pull rod 1 Instead, the connecting portion 62 connects the rod bottom end 4 and the speed increasing gear mechanism. When the handle 14 is pushed forward and pulled backward, the bottom end 4 of the rear wheel 4 moves the speed increasing gear mechanism of the rear wheel assembly 63 to move the bottom plate 5 forward.

The rear wheel assembly 63 includes a speed increasing gear mechanism 12 and a one-way device 7. The one-way device 7 drives the rear wheel 8, and the speed increasing gear mechanism 12, as shown in FIG. 2, is composed of a gear set with a small gear, and the gear set is free on the shaft center. Rotate, and connect many groups in series a gear set, each of which meshes with another set of pinions with a large gear, and the large gear attached to the pinion gear meshes with different sets of pinions, and is continuously configured until the final output gear 26 drives the one-way device 7 The rear wheel turns. All the shafts are free to rotate, which allows one gear to interlock the other gear, and the two gears are fixed to the shaft by the keys. As shown in FIG. 2, this example uses a plurality of gear sets of the same size, these gear sets are disposed on two axes, and the input and the output are all near the center point (this example is for example only, the invention is not limited thereto) ). A driving force is applied to the center of the speed increasing gear mechanism 12, and is input to the input gear 17 of the driving shaft 13, which is a gear set with the large gear 18. The large gear 18 drives another set of pinions 19 on the shaft 24 to which a large gear 20 is attached; likewise, the large gear 20 drives the other set of pinions 21 to which a large gear 22 is attached. This is continued until the fixed gear 23 on the shaft center 24. The fixed gear 23 is fixed to the shaft center 24 by a key, and the fixed gear 25 fixed by the key is interlocked by the shaft center 24. The fixed gear 25 drives the pinion gear and then attaches a large gear, so that the speed is continuously increased until the final output gear 26 is located near the center; its output to the rear axle unidirectional device causes the rear wheel to rotate, so the output gear 26 comes at a very high speed. Drive the rear wheel. Among them, the one-way device 7 is a rear axle unidirectional device of a bicycle, and the gears described later and later include driving in a chain form or a frictional contact. In addition, the speed increasing gear mechanism 12 of the present invention can also drive a generator to store energy in the battery at a high rotational speed output, and drive the rear wheel to advance the pulley by a motor.

The front wheel assembly 61 includes the front wheel 3 and the steering mechanism. At present, the steering mechanism can be generally divided into two categories: using the body weight to tilt the handle or rotating the handle by hand. The push-pull rod 1 of the present invention can further be driven by a cable pulling wire as shown in FIG. 3-3; or as shown in FIG. 1-1, the lower end of the push-pull rod 1 has a long key or a long tooth passing through a casing 29 having the same shape. The groove is fixed and the sleeve 29 is secured to the bearing inner ring 30 by a pair of sleeve pivots 28. As shown in Figure 1-3, the sleeve 29 is provided with pivot tips on both sides thereof, and is pivotally fixed to the bearing inner ring 30 of a bearing 27. Similarly, the two pivot tips can also be fixed to the bearing inner ring 30 of the bearing 27 and engaged with a pair of pivot holes on the sleeve 29, while the bearing outer ring 31 of the bearing 27 is fixed to the bottom plate 5 or to the bottom plate. 5 becomes a body. The push-pull rod 1 is pushed forward and backward by the sleeve pivot 28, and at the same time, because the long key or the long tooth is interlocked in the sleeve 29, the push-pull rod 1 will interlock the bearing when it is rotated left and right. Turn left or right to change the direction of advancement, and change the center of the lever by pushing and pulling the lever 1 up and down in the sleeve 29. In addition, an upper limit ring 37 and a lower limit ring 38 are provided to limit the range in which the push-pull rod 1 moves up and down.

As shown in Figure 1-2, the push-pull rod 1 and the sleeve 29 are combined into one body, and the push-pull rod 1 is fixed on the bearing inner ring 30 by the push-pull rod pivot 2, such as by using a pivot tip through the push-pull rod pivot hole. And placed in the bearing 27 Bearing inner ring 30. Both ends of the pivot tip straddle and are fixed to the bearing inner ring 30, and a bushing is between the push-pull rod portion and the pivot tip portion. The bearing outer ring 31 of the bearing 27 is fixed to the bottom plate 5.

The bearing inner ring 30 of the bearing 27 supports the push-pull rod pivot and is coupled to the steering mechanism. There are many ways to connect the bearing inner ring 30 to the steering mechanism, as shown in Figure 1-3 for a single front wheel application or for a double front wheel application as shown in Figure 1-4. The bearing inner ring 30 has a directional gear 33 that engages with an idler pulley 34, which in turn engages with the steering gear 35, causing the steering gear 35 to pivot about the steering fulcrum 16. The double front wheel application shown in Figures 1-4; the bearing inner ring 30 has a steering link 32 attached to the steering arm 36 of the front half parallelogram steering mechanism, such as a steering mechanism for the vehicle to steer the front wheels. The bottom plate 5 has a platform for the user to stand and operate the push-pull rod. The front end has a front wheel assembly 61 of the steering mechanism and has a bearing 27 for supporting the push rod fulcrum and a rear wheel assembly 63 at the rear end.

The link mechanism 62 is coupled between the rod bottom end 4 and the input gear 17 of the speed increasing gear mechanism 12. The input gear 17, of the speed increasing gear mechanism 12, will hereinafter be referred to simply as the input gear 17. The attachment mechanism 62 can be a variety of interlocking drive modes: a chain, a link or a rack; it further includes a plurality of shifting devices, such as an idler gear that shuttles over the shaft or in a two-chain fashion as described below.

As shown in Fig. 1, the bottom end 4 of the rod has a ball joint connected to a chain 10 surrounding the input gear 17 and attached to the bottom plate 5 by a return spring 9. When the push-pull rod 1 is pulled back, the input gear 17 is rotated, which causes the gear of the one-way device 7 to rotate and the bottom plate 5 to move forward and slide. When the handle 14 is pushed forward, the return spring 9 is pulled back, the cycle is returned and the one-way device 7 causes the bottom plate to continue to slide. The chain 10 and the chain to be described later may be various forms of pull materials such as steel wire, nylon rope or timing belt. The return spring 9 can also be attached to the pedestal for a spring.

In order to be able to apply force by the thrust, as shown in FIG. 4, the bottom end 4 of the rod is connected to a connecting rod 4a by a ball joint, and the other end of the connecting rod 4a is connected to the outer edge of a driven gear 4c by a connecting tip 4b due to The driving force of the thrust or the pulling force causes the driven gear 4c to rotate forward or backward, and the driven gear pivot 4d is fixed to the bottom plate 5. The output of the driven gear 4c is connected to the aforementioned input gear 17. In addition, as shown in FIG. 3 (the front view of FIG. 3-2), the bottom end 4 of the rod can directly engage a rack 5a with a ball joint, and the other end of the rack 5a engages a driven gear 5b, and an inertia is arranged on the back side thereof. The wheel 5c is for pressing against the detachment of the engaging teeth, and the idler shaft 5d is supported and fixed by a pair of continuous core plates 5f, and the connecting core plate 5f is pivotally fixed on the driven gear shaft 5e, and the driven gear shaft The core 5e supports the frame plate 5g fixed to the bottom plate 5, thus When the rack 5a moves back and forth, the driven gear 5b also rotates back and forth. As shown in FIG. 3-1, when the rack 5a moves up and down with the push-pull rod 1, the center plate 5f is slightly rotated by the angle of the driven gear axis 5e as an axis, so that it does not affect the connection with the driven gear 5b. The output gear 5h has an output; the output gear 5h output is connected to the input gear 17; when the push-pull rod 1 is returned, since the rear wheel has a one-way device, it is not affected; therefore, the additional idler wheel is used to change direction. It can be used to push or pull any type of sliding car.

Further, the push-pull rod 1 has a characteristic that the rack 5a and the link 4a are not allowed to move left and right, and the pair of cable cables can be used to drive the front wheel steering mechanism. The cable puller, such as a bicycle shift cable, is a bendable and simultaneously push-pull action. And a push-pull on the cable pull at the same time, will produce a pair of force arms, which can accurately make the passive mover with the same movement with the active part, such as the car shifting cable cable is the application of this type. As shown in Figure 3-3, the tension of the push-pull rod is absorbed by the two cable pull wires, and the front end of the bottom plate 5 has a long groove to accommodate the space required for the swing lever swing; the push-pull rod 1 has a cylindrical shape and passes through a The shaft sleeve 3h can be slid up and down in the shaft sleeve 3h to change the torque fulcrum, and can be rotated left and right to control the steering; and an upper limit ring 37 and a lower limit ring 38 are provided to limit the range in which the push-pull rod 1 moves up and down; The two sides of the shaft sleeve 3h are supported by a pair of pivots 3i supported by the bottom plate 5, so that the push-pull rod 1 can swing back and forth with the pivot 3i; and the outer portion of the shaft sleeve 3h is connected to a rotating plate 3a by bearings. And the rotating plate 3a has a groove 3c to allow the upper and lower movements of a long tip 3b on the push-pull rod, and the rotating plate groove 3c is driven by the long tip 3b when the push-pull rod 1 rotates left and right, so that the rotating plate 3a is rotated left and right by the rotating plate bearing 3d; and a cable pulling wire fixing plate 3f is externally provided on the rotating shaft bushing 3h to fix the outer tube of the pair of cable pulling wires 3e, and the inner wire of the pair of cable pulling wires 3e is connected to both ends of the rotating plate 3a And by the other end of the pair of cable pull 3e A pair of force arms, the linkage mechanism described in Figure 3-5 for the single-rotor application and Figure 3-8 for the double-rotor application, the front wheel steering mechanism is rotated with the push-pull rod 1 to control the front Figure 3-4 is a right side view of Figure 3-3, and Figure 3-5 is a top view of Figure 3-3. Also for the application of the fixed arm point, as shown in FIG. 3-6, the push-pull rod 1 passes under a shaft sleeve 3h supported by the bottom plate 5 to fix a pair of pivots 3i, and the push-pull rod 1 is only It can rotate left and right in the shaft sleeve 3h, and a shaft cable fixing plate 3f is arranged outside the shaft sleeve 3h to fix the outer tube of the pair of cable wires 3e, and the inner wire of the pair of cable wires 3e is connected to one of the push rods 1 A pair of force arms are generated from the opposite ends of the pair of extension cables 3e, and the pair of force arms are coupled to the steering mechanism to cause the front wheel steering mechanism to rotate with the push-pull rod 1 to rotate left and right. Figure 3-7 is a right side view of Figure 3-6, Figure 3-8 A partial top view of the portion of Figure 3-3.

Theoretically, if a 10 cm diameter wheel is pulled by a distance of 10 cm per second, and thus a speed of 20 km is required, the shift must be 55 times. Similarly, when the speed of 40 km is generated, the shift must be More than a hundred times. Although the adjustable fulcrum of the push-pull rod 1 makes the torque ratio more than 100 times, it generates enough necessary torque, but when it is stationary, it will generate excessive instantaneous internal stress to apply to the gear set and the shaft, which will cause the sliding car to start when it is stationary. Jumping or chipping, etc., therefore, there must be a low speed gear with a lower speed ratio to overcome the situation of starting from a standstill. In the same condition, if the speed is 2 km, the speed ratio is only 5.5 times, and the instantaneous internal stress is greatly reduced. Therefore, the connecting mechanism 62 also includes a shifting device. As shown in FIG. 5-1, a play fork idler 8e is clamped by a fork (not shown) and its two forks (not shown) are used to pull the fork. At the end, the play fork idler 8e is axially moved on the shaft 8d. The two pull wires are connected to a shift selector lever, like the bicycle speed selector, the pull wires are set on different gears, each gear has a certain length to position the play fork, and the broadcast fork idler is positioned at the speed increasing gear mechanism. The desired input gear within 12. The axial movement can also be moved by the centrifugal force according to the speed of the vehicle. The power of the fork idler is derived from a connector such as the chain 10, the rack 5a or the link 4a.

As shown in FIG. 5 and FIG. 5-1, the output gear 5h drives a one-way wheel 8a, and the output gear 5h has an extension shaft coupled to the other end of the same-sized extension gear 5i, and the extension gear 5i is changed by an idler gear 8k. After the direction, it reaches the one-way gear 8j (or a chain can be directly connected to the extension gear 5i and the one-way gear), and the two-way one-way gears can simultaneously drive the shaft 8m in one direction to become both push and pull. Powered push-pull car. When pushing, the one-way wheel 8a of the pushing direction drives the shaft center 8m in one direction, and the gear 8b fixed on the shaft center 8m is interlocked by the shaft center 8m, and the one-way gear 8j in the pulling direction is reversely idly returned to the position; The gear 8b fixed to the shaft 8m is transmitted to the gear 8c fixed to the shaft 8d, and the shaft 8 having the long key or the long tooth is driven to drive the matching tooth groove and the idler idler 8e. Such as bicycle shifting devices. When the user selects the shift speed, the two-wire control fork (not shown) is moved to make the shaft slide and position, so that the power of the shaft 8d is transmitted to the speed increasing gear box via the broadcast fork idler 8e. In the speed-increasing gearbox, except for the last gear 8f which finally drives the rear wheel, the rear axle 8g is driven by the one-way mechanism 8i and the rear roller skating action force makes it easy to enter, and all other gears are freely rotatable on the shaft. Because the positioning fork idler 8e moves and positions, the number of gears with increasing speed is increased or decreased, and thus the rear wheel speed is changed; when the pulling is reversed, the one-way gear 8j of the pulling direction acts, and the one-way wheel 8a of the pushing direction is reversed. It is rotated back to the position, so the loop is not stopped.

Figure 6-1 is a schematic diagram of a two-chain transmission device of two rear wheel embodiments; the gear 48 has a one-way The device drives the rear axle 49 to drive the rear wheel 8, and the remaining gears on the same shaft are free to rotate. The bottom end 4 of the rod connects the two chains 44 and 50 to the one-way driving wheels 46 and 53, respectively, and each has a reply. The spring 9 and the one-way driving wheel 46 drive the high speed gear 47 connected to the starting gear of the speed increasing gear mechanism; the one-way driving wheel 53 drives the low speed gear 52 to be connected to a gear in the middle of the speed increasing gear mechanism 12. A one-way device in each of the one-way driving wheels 46 and 53 drives the high speed gear 47 and the low speed gear 52, respectively, which can separate the one-way driving wheels 46 and 53, the high speed gear 47 and the low speed gear 52 so that they can respectively run at respective speeds. As long as the high speed gear 47 and the low speed gear 52 are faster than the one-way driving wheels 46 and 53, the high speed gear 47 and the low speed gear 52 can still rotate while the one-way driving wheels 46 and 53 are stopped. The chain 44 is provided with a slack loop 51 and is tightened by a spring 45. The slack loop 51 can be set to half the stroke of the push-pull rod, while the spring 45 force can be set at a certain force that is only sufficient to drive high speed forces. This prevents infinite internal stresses from starting and damages the gears. Therefore, if there is a heavy negative overload, the spring will be elongated first, and the chain 50 has no loose cable loop, and the pulling force to the one-way driving wheel 53 drives the low speed gear 52 through its one-way device, and immediately drives the gear 48 with high torque. The rear axle 49 and the rear wheel, the rear wheel immediately advances slowly. Since the force starts from the intermediate gear of the speed increasing gear mechanism 12, the internal stress generated by this will be smaller than when the force starts from the starting gear. The sliding car will move with the low speed gear plus the tension cable spring force on the front half tension stroke. Next, as shown in Figure 1-5, the handle changes the torque up and down and the bottom short stroke 54 and the bottom long stroke 55, which gives the user more choice to control the sliding car. When the speed is higher, the low gear will lose its function. When the slack loop 51 is straightened, the rear half tension stroke allows individual users to reach their highest speed. Figure 6-2 shows a single rear wheel application. Gears 59 and 58 are keyed to one of the shafts; gears 56 and 57 are keyed to the other shaft; operating as previously described, power from high speed gear 47 to gear 56, through shaft to gear 57, and The low speed gear 52 is connected in parallel, continues to the gear 59, passes through the shaft to the gear 58, and then the gear 48 is output to the rear wheel 8.

In addition, the push-pull rod 1 can be provided with a plurality of retractable fixing tips interlocking with the sleeves 29 and the inner holes of the shaft sleeve 3h at the same interval, such as the handlebar pull rod, press a button to make all the The fixed pin is retracted to adjust the center point, and the torque is changed, just like the shift effect. The telescopic lever function can also be used to increase the arm. In addition, for the simple collection, the push-pull rod is set as two separate members, which are returned by the screw or returned in a similar manner to the air pipe quick joint; or the connecting and bending of the connecting rod and straightening, and then a sleeve is used to cover the rotating shaft portion. fixed. The wheel of the scooter is very small compared to the wheel of the bicycle. The arrangement of the wheel of the present invention is not limited to that it must be installed at the bottom of the bottom plate 5, and can also be used. The curved bracket with the enlarged wheel can be added to the suspension system of the wheel, the brake system and so on. The sliding drive driven sliding car of the present invention can be any kind of vehicle that generates power by swinging the front and rear of the push-pull rod, such as: scooter, four-wheeled recreational vehicle snow driving vehicle, electric vehicle driven by power generation, rail maintenance board, etc. .
