CN2474382Y - Driving device of electric recreation car and scooter - Google Patents

Abstract

The utility model relates to a driving device for an electric recreation car and a scooter. An endless screw is arranged on an electro-motor, a wheel axle is arranged in the centre of a worm gear, and a unilateral bearing is sheathed between a back wheel and the worm gear. A limited wheel axle which is driven by the electro-motor can simultaneously rotate the back wheel. When the wheel axle is not driven by the electro-motor, the wheel axle immobilizes, and the back wheel can also rotate freely, so that a user can feel more labor saving for pulling. Simultaneously, the wheel axle is axially arranged in the bearing of a brake device, and an external thread post is arranged in the center of the brake device, so that the wheel axle can be locked on a fixed frame by a nut cap. Because the wheel axle is supported by the bearing, the problems of stress concentration and even breaking can not appear.

Description

The actuating device of electric recreation vehicle and Kickboard Scooter

The utility model relates to the actuating device of a kind of electric recreation vehicle and Kickboard Scooter.Mainly be worm screw to be set at electro-motor, so as to another worm gear of engaged transmission, and wheel shaft is set in the worm gear center, an and sheathed unilateral bearing between wheel shaft and trailing wheel, because the lining of unilateral bearing inner ring has the direction restriction, only can do equidirectional rotation, reversing sense then can drive the lining rotation of outer ring synchronously when rotating, so drive the usefulness of trailing wheel rotation in the time of can be as electrical motor driven, and the directionless restriction of the lining of unilateral bearing outer ring, even so wheel shaft maintains static, trailing wheel still can freely rotate, allow affect more laborsaving, in addition for fear of stress concentration on wheel shaft, especially wheel shaft is located in the bearing of brake device, is engaged in the brake device center simultaneously and sets up the outside thread post, utilize outside thread post lock to tie on fixed mount.

According to the Segway Human Transporter of conventional known, see also shown in Figure 1ly, it is a known plane combination scheme drawing.Mainly be: storage battery 12 is set in these two slide plate 11 bottoms of taking turns Segway Human Transporter 10, so as to the required electric power of supply electro-motor 13, wherein electro-motor 13 is to carry on the support body 14 at slide plate 11 rears, the sheathed gear that varies in size 18 in the rotor 17 of the wheel shaft 16 of trailing wheel 15 and electro-motor 13 respectively simultaneously, can utilize odontoid belt 19 to give trailing wheel 15, drive trailing wheel 15 synchronously and run forward the transmission of power of electro-motor 13; But on practical operation is used, still there be following problem and the defective that waits to overcome solution in the Segway Human Transporter of above-mentioned conventional known:

1, the Segway Human Transporter of conventional known mainly is to utilize gear and odontoid belt transmission, makes odontoid belt lax or tight long status, the problem that causes transmission to have some setbacks intermittently occur easily because of running vibration;

2, the gear of the Segway Human Transporter of conventional known and odontoid belt are emerging in the outside, and without any protective device causes danger easily again;

3, the Segway Human Transporter of conventional known is when affecting, owing to be subjected to the influence of odontoid belt, the rotor of electro-motor can rotate together along with trailing wheel, so just can cause the difficulty that affects to make and affect more effort;

4, the wheel shaft of the Segway Human Transporter of conventional known is directly to be located on the support body, thus stress be concentrated on the wheel shaft, thereby the problem that exists wheel shaft to rupture especially easily.

In view of this, this creator is with the spirit of positive input research and development with the innovation improvement, finishes the utility model finally and the actuating device of a kind of electric recreation vehicle and Kickboard Scooter is provided.

Therefore, the purpose of this utility model is to provide the actuating device of a kind of electric recreation vehicle and Kickboard Scooter.

The utility model relates to the actuating device of a kind of electric recreation vehicle and Kickboard Scooter, this Kickboard Scooter is the storage battery that the supply electric motor power is set in the slide plate bottom, wherein electro-motor is to be equipped on the slide plate rear, and in skateboard back-end two fixed mounts are set, and brake device, trailing wheel, set casing mounting are located on this two fixed mount; It is characterized in that, the sheathed worm and wheel of the rotor of this electro-motor and wheel shaft, usefulness as the transmission that is meshing with each other, wherein wheel shaft is to pass fixedly shell block and be located in the trailing wheel, and sheathed unilateral bearing between trailing wheel and wheel shaft, this unilateral bearing inner ring bushing has the direction restriction, the then directionless restriction of outer ring lining, advance so as to driving trailing wheel synchronously when the wheel shaft reverse drive, wheel shaft maintains static when unpowered, but trailing wheel still can freely advance or retreat, and wheel shaft is located in the bearing of brake device simultaneously, set up the outside thread post at brake device in addition, described outside thread post cooperates lock to tie on fixed mount with nut.

The utility model has the advantages that and realize by following technological means:

One the technological means of dealing with problems is: this actuating device is to utilize the worm and wheel transmission, makes the power of electro-motor can be directly passed to trailing wheel, solves because the problem that the vibration transmission that causes has some setbacks;

Two the technological means of dealing with problems is: this worm and wheel is arranged on fixedly shell block inside, so actuating device can be hidden in fixedly shell block inside, can adventurous situation not take place, and it is minimum also fault rate to be dropped to;

Three the technological means of dealing with problems is: sheathed unilateral bearing between the wheel shaft of this worm gear and the trailing wheel, can utilize the unilateral bearing inner ring bushing that the direction restriction is arranged, the outer ring lining is the effect of directionless restriction then, allowing inner ring bushing can drive outer ring lining rotation synchronously when the reverse drive of wheel shaft advances, otherwise when electro-motor does not have live axle, because the relation of the directionless restriction of outer ring lining, so even wheel shaft is motionless, trailing wheel still can freely advance or retreat, and makes the user more easily laborsaving when affecting RV recreational vehicle or Kickboard Scooter;

Four the technological means of dealing with problems is: this wheel shaft is to be located in the bearing of brake device, set up the outside thread post in the brake device center again, can tie on fixed mount by the nut lock, because wheel shaft itself is subjected to the supporting role of bearing, so stress concentration can not occur, even cause taking turns the problem of axle fracture.
