Description

Front two-wheeled vehicle structure

Technical Field

The present invention relates to a front two-wheeled vehicle structure, and more particularly to a front two-wheeled vehicle structure which is stable, easy to control, and not easy to rotate.

Background

The current consumer likes convenient two-wheeled motorcycle, to balanced control the relatively poor rider of ability, when meeting sudden situation emergency brake the easy out of control and changeing, especially when traveling in wet and slippery or uneven rubble road surface, also often can't avoid the out of control to change with the rider people that the ability preferred was controlled to the rider.

The main reasons for the turning over are discussed in that the motorcycle is provided with only one wheel at the front and rear, which provides insufficient smoothness, and the rider must balance the motorcycle by correcting the steering and changing the center of gravity of the rider and the body during the traveling of the motorcycle to prevent the motorcycle from turning over, so that the rider must have the ability to quickly control the balance in response to the situation to maintain the motorcycle from turning over. And the main reason that the two-wheel motorcycle is out of control to rotate when meeting wet and slippery road surface is that the tires and the ground lose the grip force, so that the steering correction can not be carried out to balance the motorcycle body.

Therefore, manufacturers have developed a front two-wheeled vehicle capable of preventing the vehicle from turning over, such as the conventional taiwan patent publication No. TW 201400351, which discloses a conventional front two-wheeled vehicle having a front right wheel set, a front left wheel set, and a Double a-arm suspension (Double wishbone suspension), wherein the front right wheel set is pivotally connected to a main frame through a lower link and an upper link. However, because the main frame provides insufficient space at the pivot joint of the connecting rods, the lower connecting rod and the upper connecting rod must be assembled and combined with the main frame respectively, so that multiple sets of parts are time-consuming in the production and assembly process, and the assembly operation process is not smooth due to the small assembly space.

The present invention is conceived based on the spirit of the active invention, and several studies and experiments have been completed in order to find a structure of a front two-wheeled vehicle that can solve the above problems.

SUMMERY OF THE UTILITY MODEL

The main object of the present invention is to provide a front two-wheeled vehicle structure, which reserves an assembly space at the joint of the left and right suspensions of the front wheels and the main frame, and combines the left and right suspensions of the front wheels and all the components of the lower link into an assembly structure of a lower link assembly, and then combines the assembly structure with the main frame, so as to simplify the components and greatly reduce the assembly time of the production assembly line.

To achieve the above objective, the present invention provides a front two-wheeled vehicle structure including a main frame, a power unit, at least one rear wheel set, a front right wheel set, a front left wheel set, and a lower connecting rod assembly. The main frame is provided with a front hanging and connecting lug and a rear hanging and connecting lug, the power set is arranged on the main frame, and at least one rear wheel set is connected with the power set. The front right wheel set is provided with a front right wheel bracket, and the front left wheel set is provided with a front left wheel bracket. The lower connecting rod assembly is pivoted to the front right wheel support and the front left wheel support and comprises two lower connecting rods, a plurality of circular elastic body elements and a hollow tubular shaft, the two lower connecting rods are respectively provided with at least one connecting rod seat, the hollow tubular shaft is arranged in inner holes of the circular elastic body elements in a penetrating mode and is connected into a whole, and the circular elastic body elements are arranged on the at least one connecting rod seat of the two lower connecting rods respectively and are connected into a whole.

The lower connecting rod assembly is set between the front hanging lug and the back hanging lug and has one rod shaft penetrating the inner hole of the front hanging lug, the inner hole of the hollow pipe shaft and the inner hole of the back hanging lug for hanging the lower connecting rod assembly to the main frame. Through the design and the systematic assembly mode, the number of parts can be reduced, extra wasted assembly time is saved to improve the smoothness of the manufacturing process, the size of the vehicle is miniaturized due to good space utilization, and the overall design is optimized.

Wherein, the main frame can be in a n-shaped structure from side view, and the front hanging lug and the back hanging lug can be arranged at two ends of the n-shaped structure. Therefore, through the design of the n-shaped structure, a space for placing the lower connecting rod assembly can be reserved, and meanwhile, the assembling performance and the symmetry of the structure are maintained, so that the main frame design with better space configuration is realized.

The inner hole of the front hanging lug and the inner hole of the rear hanging lug can be positioned on the same central line. Therefore, the lower connecting rod component can be arranged along the central line, so that the structure achieves the effect of axial symmetry, and the balance and the smoothness of the front two-wheel vehicle in driving are maintained.

Both the foregoing general description and the following detailed description are exemplary and are intended to provide further explanation of the scope of the utility model as claimed. Other objects and advantages of the present invention will become apparent from the following description and the accompanying drawings.
