Problems solved by technology

[0004] The first type is a motorcycle using a relatively traditional double-tube telescopic suspension system. This type of motorcycle is currently the most numerous on the market. Usually, two telescopic shock absorbers are used as structural components of the suspension system at the same time. The damping structure and oil-gas sealing device are installed inside the double cylinder, which leads to a complex structure and high requirements for materials and processing accuracy, and the telescopic cylinder needs to be responsible for both the shock absorption function and the structural force in all directions, resulting in a relatively large structural weight , the cost is relatively high
Also because the shock absorber has a forward tilt angle, it will cause the wheelbase of the vehicle to change when telescopic movement occurs, which is not conducive to handling
[0005] The second type is a motorcycle with a rocker suspension system. Figure 8 It is the structural diagram of the rocker suspension system on the existing motorcycle, such as Figure 8 As shown, this motorcycle sets the support arm as a connecting rod, and a shock absorber is arranged between the two connecting rods. Although the motorcycle with this structure is simple in structure and can withstand large structural forces, it is stable. Poor performance, not suitable for high-speed vehicles
[0006] The third type is a motorcycle using the HOSSACK suspension system. The front suspension system of the motorcycle is composed of two swingable rocker arms and an independent shock absorber. Although the stability is good, the rocker arm of this structure will occupy The large space size causes the steering vertical shaft to be forward, which is not conducive to the centralized motorcycle wheelbase, and because the steering structure will move up and down during the shock absorption process, it requires an additional connecting rod to realize the steering, resulting in a complicated structure Sex, not conducive to the design of the overall structure of the motorcycle
[0007] To sum up, the structure of the front suspension system of motorcycles currently on the market has the disadvantages of heavy weight, high cost, large wheelbase changes are not conducive to handling or poor stability and adaptability, and it is impossible to centralize the wheelbase and require another connection. The problem with the lever to achieve the steering

Abstract

The invention provides a structure of a front suspension system of a motorcycle and belongs to the technical field of motorcycle manufacturing. The structure comprises an upper connection plate fixed at the upper portion of a frame upright and a lower connection plate fixed at the lower portion of the frame upright, the upper portion of a support arm provided with a wheel is hinged to the upper connection plate through an upper rocker, the middle portion of the support arm is hinged to the lower connection plate through a lower rocker, and two ends of a damper are respectively hinged to the upper connection plate and the lower connection plate. By the arrangement of the independent damper and alloyed rockers, weight is effectively reduced, and cost is lowered; by the arrangement of a double-rocker structure, the situation that motion trail of the support arm is similar to a straight line is guaranteed during vertical swinging of the support arm, and controllability affected by change of a wheel base is avoided; the rockers are arranged in the front of the frame, swinging of the support arm is facilitated, the structure is easily centralized and simplified, and the effect of direct steering is achieved.

Description

technical field [0001] The invention relates to the technical field of motorcycle manufacturing, in particular to a structure of a motorcycle front suspension system. Background technique [0002] Motorbike is a popular means of transportation in modern times. Due to its low fuel consumption, low pollution discharge, good mobility, less restriction by road factors, and convenient parking, it has become the main means of transportation for people to travel, work and shop. . [0003] Motorcycles currently on the market are mainly divided into three types according to the structure of the suspension system. [0004] The first type is a motorcycle using a relatively traditional double-tube telescopic suspension system. This type of motorcycle is currently the most numerous on the market. Usually, two telescopic shock absorbers are used as structural components of the suspension system at the same time. The damping structure and oil-gas sealing device are installed inside the d...
