Description

Swinging tricycle

Technical Field

The invention relates to the technical field of motor tricycles, in particular to a swing tricycle.

Background

The existing motorcycle usually adopts a two-wheel or three-wheel structure, the front wheels are the steering mechanism of the motorcycle, the driver changes the advancing direction of the motorcycle by operating and rotating a handle, and the motorcycle with the three-wheel structure is easier to be mastered by the driver than the motorcycle with the two-wheel structure. The traditional motor tricycle generally adopts a structure that a single wheel is arranged in front of the tricycle and two wheels are arranged behind the tricycle, the positions of the two wheels on the rear side are fixed, a shock absorber is arranged at the part below a seat cushion, and jolts and vibrations of the tricycle during running are buffered through the shock absorber so as to improve the driving comfort. However, the tricycle has poor anti-roll capability and turning capability in the running process, the tricycle rolls when the speed is slightly high, the rollover accident is easy to happen, and meanwhile, the trafficability of the tricycle on a bumpy road surface is poor. In the prior art, a tricycle with a rear wheel capable of swinging according to a running road surface also appears, but the existing tricycle is relatively complex in support structure, troublesome in locking operation and easy to overturn when parked; how to conveniently and rapidly lock the tricycle without swinging is also a problem to be solved urgently in the prior art.

Therefore, a technical scheme aiming at enabling the motor tricycle to run more flexibly and to be suitable for different road surfaces is urgently needed in the prior art.

Disclosure of Invention

In view of the above-mentioned deficiencies of the prior art, the present invention provides a swing tricycle.

In order to achieve the purpose, the invention is realized by the following technical scheme:

a swing tricycle comprises a frame, a handlebar, front wheels, a saddle and rear wheels, wherein the rear wheels comprise a left rear wheel and a right rear wheel, and the swing tricycle is characterized by further comprising a connecting shaft, a connecting swing arm, a swing locking disc, swing locking pliers, a swing shaft, a rear bottom fork swing arm and a shock absorber, the swing locking disc is fixedly connected with the connecting swing arm, two ends of the connecting swing arm are respectively connected with the shock absorber through universal joints, the tail end of the shock absorber is rotatably connected with the rear bottom fork swing arm, the front end of the rear bottom fork swing arm is movably sleeved on the connecting shaft, the rear end of the rear bottom fork swing arm is movably sleeved on a wheel shaft of the rear wheel, and the connecting shaft is fixedly connected with the frame; the swing locking pliers are fixedly connected with the frame through locking pliers connecting pieces, the swing shaft penetrates through the locking pliers connecting pieces and the connecting swing arm, the connecting swing arm can rotate around the swing shaft, and the locking pliers connecting pieces are fixedly connected with the swing shaft; when the swing locking pliers clamp the swing locking disc, the connecting swing arm cannot rotate around the swing shaft.

The swing tricycle further comprises a hub motor, wherein the hub motor is fixedly arranged on the rear bottom fork swing arm and is connected with a wheel shaft of the rear wheel to drive the rear wheel to rotate.

The locking clamp connecting piece is fixedly connected with the swing shaft in a welding mode.

The swing locking disc is fixedly connected with the connecting swing arm through bolts.

The swing locking pliers are fixedly connected with the locking pliers connecting piece through bolts.

Compared with the prior art, the invention has the beneficial effects that: the swing shaft penetrates through the connecting swing arm and the locking clamp connecting piece and is selected, so that the motor tricycle can swing left and right according to the driving and road surface requirements, and particularly when the motor tricycle runs in a curve road in a quick cross country mode, the left rear wheel and the right rear wheel can incline left or right on the road surface; utilize the locking clamp card of swaing to die the locking dish that sways, can control the swinger and stop to sway, make motor tricycle keep steadily according to actual conditions's needs, improved the follow-up nature that the tricycle travel, simultaneously, can realize the locking of swaing the tricycle more convenient and fast ground.

Detailed Description

The invention is further illustrated by the following specific embodiments.

The swinging tricycle shown in fig. 1-4 comprises a frame, a handlebar, a front wheel, a saddle, a rear wheel, a connecting shaft, a connecting swing arm, a swinging locking disc, swinging locking pliers, a swinging shaft, a rear bottom fork swing arm and a shock absorber, wherein the swinging locking disc is fixedly connected with the connecting swing arm, and in the embodiment, the swinging locking disc is fixedly connected with the connecting swing arm through a bolt. The two ends of the connecting swing arm are respectively connected with a shock absorber through universal joints, the tail end of the shock absorber and the front end of the rear bottom fork swing arm which is rotatably connected with the rear bottom fork swing arm are movably sleeved on a connecting shaft, the rear end of the rear bottom fork swing arm is movably sleeved on a wheel shaft of a rear wheel, and the connecting shaft is fixedly connected with the frame; swing the locking pincers through locking pincers connecting piece and frame fixed connection, in this embodiment, swing the locking pincers and pass through bolt fixed connection with locking pincers connecting piece. The swing shaft penetrates through the locking clamp connecting piece and the connecting swing arm, the connecting swing arm can rotate around the swing shaft, and the locking clamp connecting piece is fixedly connected with the swing shaft. The swing tricycle further comprises a hub motor, wherein the hub motor is fixedly arranged on the rear bottom fork swing arm and is connected with a wheel shaft of the rear wheel for driving the rear wheel to rotate. When the swing locking pliers are pulled to clamp the swing locking disc, the connecting swing arm cannot rotate around the swing shaft, the swing locking disc is locked, and the tricycle stops swinging.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; the specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.
