Description

Tricycle capable of overcoming centrifugal force and swinging

Technical Field

The utility model relates to a vehicle field particularly is an overcome centrifugal force and sway tricycle.

Background

The market demand of electric vehicles in China is large, and most of the current electric vehicles are two-wheeled, so that the electric vehicles are unsafe. Although few three-wheeled electric vehicles are relatively stable and safe, the frame is not easy to incline towards the turning direction during steering, namely, although the wheels are already steered, the frame still keeps horizontal and even inclines towards the opposite direction. This causes a problem that the driver and the vehicle cannot lean to provide a sufficient centripetal force, in other words, cannot overcome the centrifugal force and an accident is liable to occur when the driving speed is too fast.

The traditional frame mainly plays a role in connecting front and rear wheels, so that the front end of the traditional frame is provided with a front wheel connecting structure, and the rear end of the traditional frame is provided with a rear wheel connecting structure.

SUMMERY OF THE UTILITY MODEL

The utility model aims at overcoming the frame of tricycle and can't be along with the operation of turning and to the direction slope that turns, lead to the unable problem that provides sufficient centripetal force.

The utility model discloses a concrete technical scheme as follows:

a tricycle capable of overcoming centrifugal force swing comprises a frame, wherein the frame is divided into a U-shaped middle part, a left rear wheel bracket and a right rear wheel bracket; the U-shaped middle part is divided into a front part and a rear part, the front end of the front part is provided with a front wheel connecting structure, the front part and the rear part are separated from each other and are connected through a middle shaft, the front part and the rear part can independently rotate around the middle shaft respectively, and two upright posts are symmetrically distributed at the front end of the front part; the front end of the left rear wheel bracket is connected with the upright post through two joint bearings, the two joint bearings are connected through threads, the middle part of the left rear wheel bracket is connected with the rear part through a left shaft, the left rear wheel bracket is fixedly connected with the left shaft, the rear part can rotate around the left shaft, and a rear wheel connecting structure is arranged at the rear part of the left rear wheel bracket; the whole frame is symmetrical left and right.

The utility model discloses a main innovation point lies in two parts around being divided into traditional integral type "U" shape middleware for the two can wind separately the axis is independently rotatory. When turning to the right, the front part inclines to the right, the rear end of the right rear wheel bracket is driven to upwarp, the left rear wheel bracket is low, the right rear wheel bracket is high, and the two rear wheels are always attached to the bottom surface, so that the rear part is always horizontal, and the two rear wheels incline to the right. If the traditional integral U-shaped middle part is adopted, the front part of the frame is difficult to incline rightwards, and sufficient centripetal force cannot be provided, so that the vehicle is turned over. And use the utility model discloses a during the frame, the front portion can be along with the turn right slope alone, the front portion with the rear portion is a contained angle, perfectly solves above-mentioned problem.

In order to realize that the front part and the rear part can independently rotate around the central shaft respectively, all parts can freely rotate within a certain angle, so the central shaft, the left shaft and the right shaft (symmetrically mounted with the left shaft) are designed, in addition, the joint bearing is also arranged, the joint bearing is divided into an upper part and a lower part, the upper part mainly realizes that the parts can relatively displace left and right, the lower part mainly realizes that the parts can relatively displace front and back, and the up-down relative displacement between the parts is realized by the central shaft, the left shaft and the right shaft.

In addition, the rear ends of the left rear wheel bracket and the right rear wheel bracket can tilt up and sink down within a certain range, so that stable driving can be kept if the rear ends of the left rear wheel bracket and the right rear wheel bracket meet the condition of rough road conditions in the running process. If the right rear wheel meets the bulge, the rear end of the right rear wheel bracket is lifted up to drive the front part to slightly tilt right, so that the rear part of the vehicle tilts left and the front part tilts right, and the whole vehicle cannot tilt in one direction.

Has the advantages that: the frame can be inclined towards the turning direction when the tricycle turns so as to provide enough centripetal force; the driving can be kept stable under the condition of rough road conditions.

Detailed Description

As shown in fig. 1, 2 and 3, the frame is divided into a "U" -shaped middle part 2, a left rear wheel bracket 51 and a right rear wheel bracket 52; the U-shaped middle part 2 is divided into a front part 21 and a rear part 22, the front end of the front part 21 is provided with a front wheel connecting structure 3, the front part 21 and the rear part 22 are separated from each other and are connected through a middle shaft 4, the front part 21 and the rear part 22 can independently rotate around the middle shaft 4, and two upright posts 9 are symmetrically distributed at the front end of the front part 21; the front end of the left rear wheel bracket 51 is connected with the upright post 9 through two knuckle bearings 6, the two knuckle bearings 6 are connected through threads, the knuckle bearings 6 are divided into an upper part 61 and a lower part 62, the middle part of the left rear wheel bracket 51 is connected with the rear part 22 through a left shaft 8, the left rear wheel bracket 51 is fixedly connected with the left shaft 8, the rear part 22 can rotate around the left shaft 8, and the rear part of the left rear wheel bracket 51 is provided with a rear wheel connecting structure 1; the whole frame is symmetrical left and right.

When turning to the right, the front portion 21 tilts to the right, the front end of the right rear wheel bracket is pressed down through the knuckle bearing 6, the rear end is lifted, and the left rear wheel bracket 51 is reversed. Since the wheels are always attached to the bottom surface, both rear wheels are inclined at the same angle to the right, the left rear wheel bracket 51 and the right rear wheel bracket 52 are also rotated at a certain angle in the clockwise direction within the allowable range of the joint bearing 6, and the rear portion 22 is kept substantially horizontal or inclined only slightly to the right (the inclination angle is smaller than that of the front portion 21).

The same principle applies to turning to the left.

The above disclosure is only for the preferred embodiment of the present invention, but not intended to limit itself, and any changes and modifications made by those skilled in the art without departing from the spirit of the present invention shall fall within the protection scope of the present invention.
