Technical Field

The invention relates to the technical field of inverted three wheels, in particular to a front double-wheel assembly device with a damping front fork of a vehicle body, capable of swinging left and right and capable of automatically returning to a positive balance.

Background

The inverted three-wheeled (including electric) motorcycle is a novel product, has better stable and safe trafficability than a two-wheeled motorcycle in a complex terrain environment, and particularly has stronger grip on the ground of a turning tire than the two-wheeled motorcycle. The reverse three-wheeled (including electric) motorcycle is obviously simpler in structure and lower in cost compared with the four-wheeled motorcycle, and is very popular with people in recent years.

Such as a standard inverted motor tricycle in france, the steering of which is achieved by electric and mechanical control of the front wheels. But the maneuverability is complex, the cost is high, and the driving is not easy to be habituated to common drivers. The domestic double front wheel assembly of Jili inverted tricycle applies the technology of four-wheel beach vehicle to it, needs the wheel track width of two-wheel great, just can ensure the stability of automobile body, and the road surface of generally narrow is difficult for passing through.

In general, the inverted motor tricycle generally adopts a left-right front double-wheel shock absorber to reduce the impact of a road surface on a vehicle body, has no vehicle body side-leaning self-aligning balancing device, and has low safety and stability when passing through a rugged road surface.

Disclosure of Invention

In order to overcome the problems in the common inverted tricycle, reduce the processing cost and simplify the production process, the invention provides a product which is mechanically and simply operated: the front double-wheel self-aligning balance assembly of the reverse three-wheel is a universal plate deformable device. The device is added with a balance mechanism which can return to the positive position and has two sides of the parallelogram doing axisymmetrical motion under the intervention of the central axis, thus solving the difficult problem of reversing the tricycle.

In order to achieve the purpose, the invention adopts the technical scheme that: a front double-wheel self-aligning balance assembly universal plate deformable device with a reverse tricycle. The device comprises a connecting component, a parallelogram axial symmetry (up-down) motion deformation self-aligning balance mechanism, a shock absorber, a mudguard, a wheel bell assembly and a tire. In the device, an upper parallelogram component, a lower parallelogram component, a left parallelogram movable frame (upper and lower) movable frame, a right parallelogram movable frame (upper and lower) and a parallelogram middle shaft fixing column are connected through a tightening bolt assembly with a bearing to form a movably deformable parallelogram, an adjustable return spring and an adjustable angle-limiting steel wire rope at the lower end of the parallelogram middle shaft fixing column jointly form an axisymmetric movement mechanism which can swing left and right and can automatically return to a positive balance, and the movable frames at the left and right sides move up and down when the parallelogram middle shaft fixing column and a motorcycle steer to connect a vehicle body movable shaft to deform the parallelogram axisymmetric (up and down) movement deformation self-return to the positive balance mechanism. In the device, a parallelogram left side (upper and lower) movable frame and a parallelogram right side (upper and lower) movable frame are respectively provided with a group of (2) shock absorbers, so that a left side and a right side shock absorption structures are formed, the two side shock absorption structures are connected with a wheel bell assembly and a tire through the other end of each group of shock absorbers, and the front double-wheel self-aligning balance assembly universal version deformable device of the reverse tricycle is formed.

After the technical scheme is adopted, the reverse motor tricycle is driven by the rear wheel, the front parallel two wheels control steering, and the reverse motor tricycle can run in a way of being vertical to the ground or inclining to the ground under the passive acting force of a rugged road to the tires and the active acting force of a driver to the vehicle body direction handle. When the inverted motor tricycle stops when meeting a red light through an intersection in normal running, a driver can support the motorcycle body to balance without feet or a motorcycle body support, and when the motorcycle stops, the motorcycle body does not fall down without being supported by the support under the condition that the motorcycle body is basically vertical to the ground. When the motorcycle is driven in a straight line, the motorcycle is supported by the front double wheels to be more stable, the front double wheels have larger ground grabbing force due to the generation of an inclined angle in the turning process, the turning speed can be improved, and the motorcycle can safely and stably pass through a turning road section. The steering angle and speed can be controlled by changing the change of the center of gravity during operation and control. Under the condition of not changing the length, width, height and tire size of the prototype two-wheel (including electric) motorcycle, the technical scheme is adopted, and the motorcycle can be widely applied to various two-wheel (including electric) motorcycles to produce a novel inverted three-wheel (including electric) motorcycle which can be driven more safely. The technical scheme can also be applied to the front double wheels of 4-wheel (including electric) motorcycles or 4-wheel light motor vehicles and electric bicycles.

According to the scheme, the steel wire rope with the limited angle (30 degrees) is preassembled at the lower end of the parallelogram middle shaft fixing column, and the vehicle body is controlled at 30 degrees when the vehicle turns and heels, so that the vehicle is more stable and safer in driving.
