Problems solved by technology
[0004] In order to solve the above-mentioned shortcomings, the difficulty of frame design will be increased, and the structure of the frame will be complicated, and more materials will be used, making it difficult to manufacture, and the overall cost will increase.
[0005] In addition, in the suspension structure of a conventional locomotive, the connection between the buffer mechanism 68 and the rear frame 67 is located under the seat. Although the buffer mechanism can absorb the vibrations transmitted from the road surface, it is directly pivoted under the seat because of its direct pivoting. The body will still feel vibration due to bumps in the road, so the impact force felt by the rider is more obvious

Embodiment Construction
[0026] Refer to the following figure 1 Referring to Fig. 5, the embodiment of the present invention will be described in detail.
[0027] Suspension structure of the present invention such as figure 1 As shown, it is mainly composed of a buffer mechanism 18 and a link mechanism 17 combined with the down tube 13 of the vehicle frame. The locomotive to which the present invention is applicable is not limited to figure 1 As shown, all locomotives that need to adopt a central buffer mechanism can use the suspension structure of the present invention.
[0028] Fig. 2 and Fig. 3 are top view and side view of the implementation state of the suspension structure of the present invention. The down tube 13 of the vehicle frame extends from the bottom of the head tube 11 toward the rear of the vehicle body along the center line of the vehicle body. The link mechanism 17 includes an engine hanger 15 and linkage rods 161a, 161b, 162a, 162b, wherein the engine hanger 15 can be pivota...

The invention aims at providing a suspension structure of a locomotive, which is characterized by comprising a buffering mechanism and a link mechanism. The buffering mechanism leads one end thereof to be pivoted with a lower tube of a chassis and the other end to be pivoted with the link mechanism; and the link mechanism comprises an engine suspender and is pivoted with the lower tube. The suspension structure not only has the effects of shock resistance and buffering but also has the effects of simplifying the structure of the chassis and strengthening the chassis.
Description
technical field [0001] The invention relates to a suspension structure, in particular to a suspension structure for locomotives. Background technique [0002] The side view of the frame of a conventional locomotive is as follows Figure 6 As shown, it has a down tube 63 (down tube) as the main backbone. The down tube 63 extends from the bottom of the head tube 61 along the centerline of the vehicle body toward the rear of the vehicle body. The rear end of the down tube 63 is connected to an engine hanger 65 in a pivotal manner . The rear frame 67 extends from the rear end of the down tube 63 to the rear of both sides. The rear portion of the rear vehicle frame 67 is connected with a buffer mechanism 68, and the other end of the buffer mechanism 68 is connected with the engine hanger 65 beside the rear wheel 69. In the vehicle frame, the rear vehicle frame 67, the buffer mechanism 68 and the engine hanger 65 form a suspension structure. [0003] Yet in the suspension struc...
