Abstract

The utility model discloses a front wheel steering mechanism of a gourd-shaped multi-wheel scooter, which is composed of a gourd-shaped structure, a spherical constraint, an arc-shaped slide bar, a locking structure and fixing devices at both ends. The restraint and arc-shaped slide bar is connected to the front wheel axle, and is connected to the front bar and cross member through the fixing device at both ends. Its steering principle is that the gourd-shaped structure rotates around the spherical constraint and slides along the arc-shaped slider to drive the steering of the front wheels of the vehicle, and realize the driven steering of the rear wheels through linkage.

Description

Gourd-shaped multi-wheel scooter front wheel steering mechanism

technical field

The utility model relates to a front wheel steering mechanism of a gourd-shaped multi-wheel scooter, in particular to a front wheel steering mechanism of a three-wheel or four-wheel scooter.

Background technique

At present, the front wheel steering mechanism of the simplest known three-wheel or four-wheel scooter is realized by connecting two angled cylindrical restraints respectively by the front bar and the beam. This kind of steering mechanism is simple in principle and low in cost, but it is too sensitive to control, and it is easy to rollover when moving at high speed; moreover, the scooter with this mechanism has the problem that the rotation angle of the front pole is not easy to limit , so it can easily slip off when parked against an object. Other mechanisms, such as the use of link mechanisms, are relatively complex and not flexible enough, and the manufacturing cost is also high, so it is difficult to meet market demand.

Utility model content

In order to overcome the problems of the existing three-wheel or four-wheel scooter steering mechanisms that are easy to rollover and difficult to park, and other alternative mechanisms are too complicated and the manufacturing cost is high, the utility model provides a gourd-shaped multi-wheel pedal Front wheel steering mechanism. The steering mechanism can not only realize flexible and fast steering, but also can effectively lock the swing angle of the front pole, so as to overcome the problems of rollover and slipping when docking.

The technical scheme adopted by the utility model to solve the technical problem is: on the shaft connecting the front two tires, a freely rotatable spherical restraint is set, and a ball is connected to the spherical restraint to form a structure similar to a gourd. The ball above runs through a section of arc-shaped sliding rods with 40 degrees left and right. Wherein the lower ball is connected with the beam that fixes the pedal, and the upper ball is connected with the front rod that fixes the handlebar. The two spheres form a spherical restraint device that defines the direction, so as to realize the free steering of the scooter. At the same time, because the arc-shaped slide bar is limited within a certain arc, it plays the role of locking the angle.

The beneficial effects of the utility model are: the free steering of the front wheel of the scooter can be easily realized, the locking of the sliding angle of the front rod can be easily realized, and the problem that the scooter is easy to slip when it is put on the back is solved. The utility model has the advantages of simple structure and convenient use.

6-Threaded Fixing Device 7-Reinforced Fixing Device 8-Front Rod 9-Beam 10-Pedal

11-Spherical shaft 12-Plastic bushing 13-Spherical constraint.

As shown in Figure 1 and Figure 2, the gourd-shaped structure is composed of a structural front cover 4, a structural rear cover 5 and a plastic bushing 12, and the front and rear parts fix the plastic bushing 12 on the circle through a screw fixing device 6 and a strengthening fixing device 7. Around the arc slide bar 2 and the spherical shaft 11. The upper end of the gourd-shaped structure is connected with the front rod 8 through the threaded fixing device 6 , and the rear end is connected with the crossbeam 9 through the threaded fixing device 6 . Arc-shaped slide bar 2 and locking device 3 are fixed on the front wheel shaft 1, and locking device 3 and arc-shaped slide bar 2 are integral, because the diameter of locking device 3 is larger, so played the effect of locking sliding. The gourd-shaped structure can freely slide in the range of 40 degrees left and right on the arc-shaped slide bar 2 . In addition, the gourd-shaped structure can also rotate around the spherical shaft 11 fixed on the front wheel shaft 1, thereby driving the rotation of the entire front wheel. It is the sliding and turning of the gourd-shaped structure that easily realizes the steering of the front wheels of the vehicle. As shown in Fig. 2, the threaded fixing device 6 includes 5 threaded connections and 4 pins for fixing, two pins are welded on the front cover 4 and the back cover 5 of the gourd-shaped structure respectively at the upper and lower joints of the pins, the front rod 8 and the rear cover 5 There is a gap on the beam 9 to cooperate with it.

As shown in FIG. 3 , the beam 9 is connected to the rear axle through a spherical restraint device 13 . Thereby realize the driven steering of rear wheel.
