Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
The present embodiment will be described in detail with reference to fig. 1 and 2. The steering driving gear box capable of being automatically separated related to the embodiment comprises a driving disc 1, a transmission disc 4 and a movable part 2.
The drive plate 1 is provided with a magnet 3 and a slide 6, and the slide 6 has an open end on the outer peripheral surface of the drive plate 1. The slideway 6 can be arranged on the surface of the driving disk 1, or can be arranged inside the driving disk 1. The movable part 2 is positioned in the slideway 6 and can reciprocate back and forth along the slideway 6. And when the movable part 2 moves in the slideway 6, one end of the movable part 2 can slide out from the open end of the slideway 6 and is contacted with the transmission disc 4, so that the power transmission of the driving disc 1 and the transmission disc 4 is realized. After the movable part 2 is displaced, the driving disc 1 and the transmission disc 4 are connected to drive the transmission disc 4 to rotate. The transmission disc 4 is connected with a transmission mechanism and transmits power outwards.
When mounting, driving disk 1 and driving disk 4 are concentric, and driving disk 4 is located outside driving disk 1, and in this embodiment, there is a clearance between the inner peripheral surface of driving disk 1 and the outer peripheral surface of driving disk 4. The driving disc 1 is connected with a driving motor, and the motor drives the driving disc 1 to rotate so as to provide power for the driving disc 1. The transmission disc 4 is provided with transmission teeth 5, and the transmission teeth 5 protrude out of the inner surface of the transmission disc 4 and are positioned in a gap between the driving disc 1 and the transmission disc 4.
The movable part 2 is made of a material which is easy to be attracted by magnetic force, and the driving disc 1 and the transmission disc 4 are made of a material which is not easy to be attracted by magnetic force. In this embodiment, the movable part 2 is a rectangular block made of iron, or may be formed in other ways, and can slide in the slideway 6, and when sliding out of the open end of the slideway 6, the movable part contacts with the transmission gear 5 to drive the transmission disc 4 to rotate, so as to realize power transmission. The number of the driving teeth 5 is the same as that of the slide ways 6 and the driving teeth 5 and the slide ways 6 need to be correspondingly arranged.
In this embodiment, the magnet is an electromagnet, and when the power is turned on, a magnetic field is generated around the magnet to generate a magnetic force on the movable member.
More specifically, the electromagnet in this embodiment is annular, and the slide rails 6 are provided on both sides of the annular magnet symmetrically. The slide 6 can be arranged at a plurality of positions, and the number of the slide can also be multiple. In the present embodiment, the number of the slide ways 6 is 2, and the included angle between two slide ways 6 is 180 °. The arrangement is to ensure that the stress of the driving disc 1 and the transmission disc 4 is more uniform when power is transmitted, and the service life of the steering driving gear box is ensured. The included angle of the transmission gear 5 is also 180 degrees, and the included angle is the same as that of the slide way, so that the two movable parts 2 can be ensured to be contacted with the transmission gear 5 to transmit power.
If the number of the slide ways 6 is 3, the included angle of the adjacent slide ways 6 is 120 degrees, and the included angle of the adjacent transmission teeth 5 is also 120 degrees.
In this embodiment, the movable member is made of iron, so that the movable member is stressed in the magnetic field of the magnet. The driving disc and the transmission disc are made of plastic or aluminum, and particularly are made of plastic.
The working principle of the steering drive gear box capable of being automatically separated according to the embodiment is as follows:
before the driving motor rotates, the movable member 2 is positioned near the magnet 3 due to the magnetic force. When driving motor drives driving-disc 1 and rotates, improve at the rotational speed of driving-disc 1 for the centrifugal force that movable part 2 received increases, when being greater than magnet 3 and giving movable part 2's magnetic force, movable part 2 will be along sliding 6 to the direction motion of keeping away from driving-disc 1 centre of a circle, takes place the displacement along slide 6 to the direction of driving-disc 4 promptly. When the displacement of the movable part 2 increases and one end thereof slides out of the open end of the slideway 6, it will contact with the driving gear 5. At the moment, one end of the movable part 2 is positioned in the slideway 6, one end of the movable part is contacted with the transmission gear 5, and the transmission gear 5 is fixed with the transmission disc 4, so that the driving disc 1 is contacted with the transmission disc 4, and the transmission of power is realized.
When the driving motor does not provide power for the driving disc 1, the rotating speed of the driving motor is smaller and smaller, the centrifugal force applied to the movable part 2 is smaller, and when the centrifugal force is smaller than the magnetic force applied to the movable part 2, the movable part 2 can move towards the direction close to the center of the driving disc 1 along the slide rail 6, so that the movable part 2 is separated from the transmission teeth 5, the driving disc 1 is separated from the transmission disc 4, and no power is transmitted between the driving disc 1 and the transmission disc 4.
The utility model relates to a can the autosegregation turn to the drive gear box can satisfy no matter be drive-disc 1 forward rotation, still during the antiport, all can make contact and separation that drive-disc 1 and driving disc 4 can be automatic.
Example two
This embodiment will be described in detail with reference to fig. 3 and 4. The present embodiment relates to an automatically separable steering drive gear box, which is different from the first embodiment in that:
the magnet 3 used in this embodiment is a rectangular magnet. The rectangular magnet is positioned at the end part of the slideway close to the center of the driving disk. I.e. the number of magnets 3 is the same as the number of movable parts 2.
EXAMPLE III
This embodiment will be described in detail with reference to fig. 5. The present embodiment relates to an automatically separable steering drive gear box, which is different from the first embodiment in that:
the driving disk 4 described in the first embodiment is provided with driving grooves 7 instead of the driving teeth 5 provided in the first embodiment. The drive groove 7 is recessed in the inner surface of the drive disc 4. And the setting requirement of the transmission grooves 7 is consistent with the setting requirement of the transmission teeth 5, namely the included angle of the adjacent transmission grooves 7 is the same as that of the adjacent slide ways 6, and the transmission grooves 7 and the slide ways 6 are uniformly arranged on the circumference. And the width of the transmission groove 6 is larger than that of the movable part 2, so that the movable part 2 can move into the transmission groove 7 more easily when rotating.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
