Art

Usually bikes are divided into three types: conventional Bicycle as a vehicle, mountain bike, used exclusively for the movement in the mountains, and bikes, used for sports. All of the above contain bike, mainly the front and rear wheels located in front of and behind the Bicycle frame, and two pedals between the wheels as a source of power. Driving force for Bicycle is formed by rotation of the pedals and then the force is transmitted to the rear wheel sequentially through the drive sprocket, the chain and the driven sprocket. However, most bikes can move forward only if the pedals are rotated forward. This means that the bike can't move forward if you pedal backwards. This type of unidirectional bike quickly causes fatigue in the legs of the cyclist and leads to uneven development of muscles when riding in several cadence in two directions, which would be applicable to conventional unidirectional bike. Developed to date device for cadence in two directions, which allow you to move the bike forward while pedaling forward and backward, can be roughly divided into three types depending on the used method. Used three ways: auxiliary transmission, bevel gear and planetary gear. Under the device for cadence in two directions understand the device with which the bike can move forward while pedaling forward or backward, at the same time, if necessary, it is also possible idling when the respective switching lever when pedaling backwards, as in a conventional Bicycle.

As sources relating to a device for rotation of the pedals in two directions include the following. Mantzoros and other (EPO Publication N 0369925) propose a device for cadence in two directions, using the auxiliary transmission, foster (U.S. patent N 5435583) describes a device for rotating the pedals in two directions using a bevel gear transmission and a clutch, and a real savernow transfer.

The above invention have in common the presence of an intermediate transmission (auxiliary transmission, bevel gear and a planetary gear) for changing the direction of power, but they have differences in the way of changing the direction of power, the degree of load distribution on the individual parts while changing the direction of power, precision parts and compatibility with a conventional bike. However, all inventions are designed to be installed on the axis of the pedal and not on the axis of the rear wheels.

In particular, a device for rotating the pedals in two directions (PCT application N/KP 96/00236), invented by the applicant, has several advantages in terms of accuracy, detail, smoothness of power changes, compatibility with a conventional bike by installing the axis pedals. However, the shape of the sprocket and crank differ from those used in conventional bike, so that these parts must be replaced when installing the unit on a conventional bike.

In addition, as a device for cadence in two directions, invented by the applicant, is mounted outside on the axis pedals similar to the above device, the device is out of RA is allivate protruding out of the frame of the Bicycle device for cadence in two directions on the newly designed bikes, which can be folded for transportation.

Thus, the above problems have led to the need to develop a new device for cadence in two directions, which can be installed on the axis of the rear wheels.

On the other hand to reduce foot fatigue during pedaling and more efficient use of energy, applied to the pedals, rhythm, cadence and attached to the pedal force must be constant. Developed transmission for a Bicycle, which satisfies these conditions, which adjusts the gear ratio between the leading and the trailing asterisks, correctly applying the effective pedal force in accordance with the resistance to movement of the bike.

The transmission quality can be used to transfer the external and internal type. External transfer directly changes the gear ratio, applying the chain sequentially on multiple sprockets of different diameters, which are mounted on the pedal axle and on the rear sleeve. Internal transfer can be much smaller in comparison with the external gear and protected from the external impact of the flow of dust and foreign substances, as int is carried out in the usual rental. As an example of the invention relating to internal transfer, can here be called Japanese published patent N Heisei 5-65094 (3 March 1993).

There are also other inventions related to the internal transmission installed in the rear hub, which aim to improve the efficiency of the transmission or to improve the management ratio. However, no known internal gear, which includes a device for rotating the pedals in two directions for changing the direction of power.

As mentioned above, most devices for cadence in two directions was mounted on the pedal axle, and not on the axle bushing rear wheels. In addition, most of the inventions related to the axis of the sleeve, limited only by the transmission, and it is difficult to find a design for universal bike, which contains both upload and device for cadence in two directions.

There is therefore a need for a versatile bike with a device for rotation of the pedals in the two directions for the balanced development of the muscles of the legs and transfer to effectively use applied to the pedals energy, and at the same time the feature is>The aim of the present invention is to provide a universal device for a Bicycle, which provides optimum efficiency and uniform development of the muscles of the legs while riding on the bike.

The first and second star wheels 101 and 102 are made on the inner walls, respectively, the left and middle part of the body. The housing 100 of the sleeve drives the rear wheel of a Bicycle, taking power from the first ring gear 30 (medium or high speed) or from the first led (low speed). Simultaneously, the housing 100 of the sleeve acts as a shroud to protect the parts used in the device power conversion according to the present invention. The right end of the housing 100 of the sleeve is closed by a cover 103.

In Fig. 1 and 2 position 6 indicated nuts for fixed connection device power conversion according to the present invention with the axis of the sleeve 10 and the position 7 - bearings for smooth rotation device power conversion.

The operation of the device power conversion according to the present invention having the above construction is as follows.

The device power conversion according to the present invention controls the direction of rotation power is the power it is advisable to describe in relation to the direction of rotation of the applied power in the direction of clockwise and counterclockwise.

Case application of power in a clockwise direction, is provided below. Thus, after describing the process prior to the application of power to the section II devices cadence in two directions, followed by a description of the process of changing the speed in the first stage (low speed), the second stage (medium speed) and third level (high speed).

First, when the application of power to the device power conversion in the clockwise direction, i.e., when the driven sprocket 94 is rotated clockwise, the drive wheel 90 is fixedly connected to the driven sprocket 94 also rotates clockwise. In this case, as shown in Fig. 10A, the tabs 91 of the drive wheel 90 raise fourth pawl 84 (shown by dashed lines) of the third carrier 80. In the fourth pawl 84 out of engagement with the fourth ratchet 72 ratchet wheel 70 and simultaneously fifth pawl 85 (shown in solid lines) of the third carrier 80, which is not raised, are in engagement with the fifth ratchet 54 of the second ring gear 50 under the action of elastic springs 87 dogs (Fig. 1). Thus, the drive wheel 90, the third led 80 and the second ring gear tiget second ring gear 50 without changing the direction of rotation and is then transmitted to the section I of the transmission to change the speed of rotation of the first second or third degree.

With the help of Fig. 11 below describes the process of changing the rotation speed in the first stage using section I of the transmission. A precondition for changing the rotation speed of the first stage is the fact that some of the second ends of the dogs 33 of the first ring gear 30 should be raised with the help of third pins 41 of the clutch 40 by the tension lever 3 to release the second dogs 33 out of engagement with the second ratchet 102, the housing 100 of the sleeve.

When pulling one end of the lever 3 the other end of the lever 3 is pushed to the right by the lever rule based on the axis 8 that is installed on the axis of the sleeve 10, so that, as shown in Fig. 11, the clutch 40 is moved to the right. In line with this, the key 44 of the clutch in contact with the other end of the lever 4, the retainer ring 43 and the ring 45 of the clutch pressed to each other by moving the clutch 40 to the right.

When the rotation speed of the first stage power, as shown in Fig. 11, is transmitted sequentially to the second ring gear 50, the first ring gear 30, the first led 20 and the housing 100 of the sleeve. When the transmission of power from the first ring gear 30 of the planetary gear number is the first number in accordance with the General principle of the change of the rotation speed.

The process of changing the rotation speed of the second stage is described below using Fig. 12. Prerequisite changes the rotation speed of the second stage is the fact that third pins 43 of the clutch 40 should be located near the second dogs 33 of the first ring gear 30 by pulling the lever 3 at the half. Accordingly, the power applied to the second annular gear wheel 50 is transmitted only to the first ring gear 30, but not on the first carrier 20. At the same time as the clutch 40 does not reach the second dogs 33, the second pawl 33 of the first ring gear 30 are in engagement with the second ratchet 102 of the housing 100 of the sleeve.

As shown in Fig. 12, when the rotation speed of the second stage power is transmitted sequentially to the second ring gear 50, the first ring gear 30 and the housing 100 of the sleeve. When power is applied to the first annular gear wheel 30 and then transmitted to the body 100 of the sleeve, the speed being applied and transmitted power is the same due to the same gear ratio. Thus, although the first carrier 20 being in engagement with the first annular gear wheel TAC as the first carrier 20 rotates at reduced speed.

The process of changing the rotation speed in the third degree with section I of the transmission is described below using Fig. 13. The prerequisite for the transition to third level speed is that third pins 41 of the clutch 40 should be engaged with the key grooves 24 of the first carrier 20 when the lever remains in its original position without moving.

At the third stage, the rotation speed of the power, as shown in Fig. 13, is transmitted sequentially to the second ring gear 50, the clutch 40, the first led 20, the first ring gear 30 and the housing 100 of the sleeve. The power applied to the second annular gear wheel 50, is passed directly to the first carrier 20 via the clutch 40, bypassing the first ring gear 30, as the rotation speed increases if the power is transferred from the first carrier 20 to the first ring gear 30. This means that since the first ring gear 30 rotates faster than the second ring gear 50, the third pawls 55 are not in engagement with the third ratchet 32.

Secondly, when the application of power to the device power conversion in the direction against oshodi as follows. In this case, the driven sprocket 94 is rotated counterclockwise, the drive wheel 90, United still driven sprocket 94 also rotates counterclockwise together with the driven sprocket 94. In this case, as shown in Fig. 10B, the tabs 91 of the drive wheel 90 is lifted fifth pawl 85 (shown in solid lines) of the third carrier 80. In the fifth pawl 85 disengage from the fifth ratchet 54 of the second ring gear 50 and simultaneously the fourth pawl 84 (shown by dashed lines) of the third carrier 80, which is not raised, are in engagement with the fourth ratchet 72 ratchet wheel 70 by means of elastic springs 87 dogs (Fig. 1). Thus, the drive wheel 90, the third led 80 and the ratchet 70 together rotate counterclockwise.

When power is transmitted from the drive wheel 90 in a counterclockwise direction reaches the ratchet wheel 70 without changing the direction of rotation, a ratchet wheel 70 transmits power to the small gear two-stage planetary gears of the second carrier 60. In this two-stage planetary gears 63 change the direction of rotation of the power in the clockwise direction gear two-stage planetary gears 63. Thus, the direction of rotation of the power applied to the drive wheel 90, a counterclockwise direction is changed to a clockwise direction when passing ratchet wheel 70 and the second carrier 60, so that the second ring gear 50 rotates clockwise. The process of transferring power to a section of the first transmission after the power transferred to section II of the device for rotation of the pedals in two directions, the same as in the application of power to the drive wheel 90 clockwise.

In the two-stage planetary gears 63 used in the device power conversion according to the present invention, the ratio of the diameters of each pair of gear wheels forming a two-stage planetary gears 63, is chosen so that the speed of the transmission power from the second carrier 60 to the second ring gear 50 has been constant. However, the ratio of the diameters of the small and large gears two-stage planetary gears 63 may be, if necessary, the variables to increase or decrease the speed in section II devices cadence in two directions. Thus, the rotation speed may varies the application of the power Converter unit power at idle the drive wheel 90 is described below using Fig. 10C.

Idling speed of the drive wheel 90 is only possible with the application of power in a counterclockwise direction, and power is transmitted in the same way as in the application of power in a clockwise direction.

Prerequisite idling of the drive wheel 90 is that the pin 98 (Fig. 1 and 2) should be extracted from the holes 92, is made around the circumference of the left side of the drive wheel 90 through the pull rod lever 4.

This state is shown in Fig. 10C, which is different from the state in Fig. 10B that the fourth pawl 84 is also raised by the pin 98. This condition means that the fourth and fifth dogs 84 and 85 of the third led 80 removed from the mesh, respectively, with the fourth and fifth star wheels 72 and 54. In accordance with this power from the drive wheel 90 may not be transferred to section II of the device for rotation of the pedals in two directions, so that the drive wheel 90 rotates in idle mode.

As shown in Fig. 1, in addition, the ring 88 to hold the third led 80 is placed between the third planet carrier 80 and the ratchet wheel 70 to prevent rotation of the third carrier 80 during rotation of the drive power conversion for a Bicycle hub according to the present invention allows to freely change the direction and speed of the supplied power using levers.

This device has excellent compatibility with conventional Bicycle parts, so that the present device can be simply installed on a conventional bike. In addition, the present device can move the bike forward regardless of the direction of the applied power and provides, if necessary, the idle speed when the rotation of the pedals in the opposite direction as most bikes. Additionally, you can adjust the speed in three steps. However, changing the speed of three or more stages is possible with a partial shift used in the device details.

When riding on the bike with the installed device according to the invention, the musculature of the legs of the cyclist can develop evenly and at the same time can be used effectively power applied to the pedals.
