According to the modification of the driving force switching device of the combination of the present invention, the first one-way bearing allows the rotating shaft to transmit power to the first driving device when the rotating shaft rotates in a first rotating direction, and the second one-way bearing allows the rotating shaft to face When the second rotation direction is rotated, the power is transmitted to the second driving device; respectively, for controlling the movement mode of the vehicle to advance or reverse.

Referring to Figures 1, 2 and 3, the combination of the creation of the driving force switching device of the rotating shaft comprises a rotating shaft connected to the power source; respectively, which are denoted by reference numerals 70 and 80, respectively. The power source 70 (numbered in Figure 3) can be selected from a motor, internal combustion engine or engine type such that the rotating shaft 80 produces rotational power in a counterclockwise or clockwise direction. To facilitate the description of the embodiment, the counterclockwise direction of rotation of the rotating shaft 80 is defined as a first direction of rotation, and the direction of rotation of the rotating shaft 80 is defined as a second direction of rotation.

The figure shows that the rotating shaft 80 is provided with a first driving mechanism 10 and a second driving mechanism 20. The first drive mechanism 10 selects a reduction gear mechanism including a (deceleration) drive wheel 11 and a (deceleration) driven wheel 12; the drive wheel 11 and the driven wheel 12 form a mutual transmission or meshing configuration.

Specifically, the driving wheel 11 is coupled to a first one-way bearing 30 on the rotating shaft 80, so that the driving wheel 11 rotates in response to the rotating shaft 80 in the first rotational direction (or the counterclockwise direction) to rotate synchronously; The rotating shaft 80 is rotated in the second rotational direction (or clockwise rotational direction) to form an idling motion.

In the embodiment taken, the driven wheel 12 of the first drive mechanism 10 is keyed to an input shaft 85 using a key 45; therefore, the driven wheel 12 and the input shaft 85 form a synchronously rotating configuration. In a specific embodiment, the input shaft 85 is provided with an input gear set 50 and a shift control portion 55. According to the figure, the input gear set 50 selects a four-speed transmission system.

Figures 1, 2 and 3 also depict the second drive mechanism 20 including a drive wheel 21 and a driven wheel 22; the drive wheel 21 and the driven wheel 22 form a mutual transmission. The driving wheel 21 is coupled to a second one-way bearing 40 on the rotating shaft 80, so that the driving wheel 21 rotates synchronously in response to the rotating shaft 80 in the second rotating direction (or clockwise direction); and the rotating shaft 80 faces The first rotational direction (or the counterclockwise rotational direction) rotates to form an idling motion.

In a possible embodiment, corresponding to the positions of the first one-way bearing 30 and the second one-way bearing 40, the rotating shaft 80 is provided with at least one or a plurality of bearings 35 for assisting in fixing the first one-way bearing 30, Two one-way bearing 40. The figure shows that the two sides of the first one-way bearing 30 and the two sides of the second one-way bearing 40 are respectively provided with (ball) bearings 35.

The figure also shows that the driven wheels 22 of the second drive mechanism 20 are combined on a power output shaft 90. Relative to the input gear set 50, an output gear set 60 is mounted on the output shaft 90; this output gear set 60 also selects a fourth speed drive system. In the embodiment taken, the output shaft 90 is provided with a differential mechanism 65 and an output shaft 66. Both ends of the output shaft 90 are used to pivot the wheel W, such as the depicted portion of the imaginary line in the figure.

And, the output gear set 60 is rotatably mounted on the output shaft 66 of the differential mechanism 65. Therefore, when the rotational power of the input shaft 85 is driven by the input gear set 50 to rotate the output gear set 60, the output gear set 60 will drive the differential mechanism 65 and the output shaft 66 to rotate, so that the output shaft 90 generates different rotational speeds. The wheel W rotates.

The structural cooperation and transmission of the above-described input gear set 50, shift control unit 55, output gear set 60, differential mechanism 65, output shaft cylinder 66, and the like are well-known techniques and are not described in detail.

It should be noted that the above-mentioned drive wheel 21 and the driven wheel 22 of the second drive mechanism 20 form a mutual transmission type. In a possible embodiment, a driving belt 23 (for example, a belt, a chain or the like) is disposed between the driving wheel 21 and the driven wheel 22, and the driving wheel 21 and the driven wheel 22 are connected; that is, active The power of the wheel 21 drives the driven wheel 22 to rotate via the belt 23.

Referring to FIG. 3, the power cooperates with the first one-way bearing 30, assuming that the power source 70 drives the rotating shaft 80 to rotate in the first rotational direction (viewed from the left side in the figure, as indicated by the arrow portion in the counterclockwise direction). The driving wheel 11 of the first driving mechanism 10 is synchronously rotated with the rotating shaft 80; and the driving wheel 11 directly drives the driven wheel 12 to rotate the input shaft 85 in a clockwise direction. Therefore, the input shaft 85 will synchronously rotate the input gear set 50, and transmit the power to the differential mechanism 65, so that the output shaft 90 (counterclockwise rotation) drives the wheel W to rotate, and drives the vehicle to generate forward motion.

It can be understood that the second drive mechanism 20 forms an idling motion due to the second one-way bearing 40, so that the drive wheel 21 of the second drive mechanism 20 does not transmit power to the driven wheel 22.

Referring to FIG. 4, the power cooperates with the second one-way bearing 40, assuming that the power source 70 drives the rotating shaft 80 to rotate in the second rotational direction (viewed from the left side in the figure, as indicated by the arrowwise direction). The driving wheel 21 of the second driving mechanism 20 is synchronously rotated with the rotating shaft 80; and the driving wheel 21 (via the driving belt 23) drives the driven wheel 22 to drive the output shaft (the output shaft 66 and the differential mechanism 65) in the clockwise direction. 90 (clockwise) rotation, which drives the wheel W to rotate, driving the vehicle to produce a retreating motion.

The above figures 3 and 4 show that the transmission force switching device can be used to control the forward and backward movement of the vehicle by setting or fitting the first one-way bearing 30 and the second one-way bearing 40 via the rotating shaft 80. Compared to the old law, it is more streamlined and simpler in terms of operation and coordination.

The transmission force switching device is compared with the prior art. The improved structural fit pattern is specially designed and arranged to have a different configuration than the conventional one; for example, the structural transmission of its power transmission via the rotating shaft 80 and the first one-way bearing 30 and the second one-way bearing 40 The first drive mechanism 10 or the second drive mechanism 20 is selectively driven. 2. The improved structural fit of the transmission force switching device makes its operation and power transmission more simple and direct, and changes its power transmission mode, which is also different from the power transmission and motion mode of the old method. .

Therefore, this creative department provides an improved structure of an effective safety helmet. Its spatial form is different from the conventional ones, and it has the advantages unmatched in the old law. It shows considerable progress and is fully consistent. The requirements of the new patent.
