Detailed Description
The present invention will be described in further detail with reference to the following embodiments and accompanying drawings.
1-3, the motorcycle engine suspension connection structure comprises a motorcycle frame 5 and an engine 4, wherein the motorcycle frame 5 wraps the upper part and the rear part of the engine 4 in a semi-surrounding structure. The rear part of the motorcycle frame 5 is provided with a rear suspension upper mounting bracket 6 and a rear suspension lower connecting plate 7. An upper connecting point at the rear part of the engine 4 is connected with the rear suspension upper mounting bracket 6; the lower connecting point at the rear of the engine 4 is connected with the rear suspension lower connecting plate 7. An upper suspension bracket is provided above the front portion of the motorcycle frame 5 with respect to the engine 4. The upper suspension bracket comprises a left upper suspension bracket 1 and a right upper suspension bracket 2. The lower parts of the left upper suspension bracket 1 and the right upper suspension bracket 2 are hinged with one end of the front part of a suspension lower bracket 3, and the other end of the suspension lower bracket 3 is connected with the rear suspension lower connecting plate 7. The connecting point of the front part of the engine 4 is connected with the lower suspension bracket 3, and the upper suspension bracket and the lower suspension bracket 3 jointly form a semi-surrounding structure for wrapping the front part and the lower part of the engine 4.
The invention adopts a combination form of a left upper suspension bracket 1, a right upper suspension bracket 2 and a lower suspension bracket 3; the assembly sequence is that firstly, an engine 4 is assembled on a motorcycle frame 5 through a rear suspension upper mounting bracket 6 and a rear suspension lower connecting plate 7, then a suspension lower bracket 3 is in rigid connection with the engine 4 through a middle mounting hole, and a rear mounting hole of the suspension lower bracket 3 is in rigid connection with a lower mounting hole of the rear suspension lower connecting plate 7; the upper ends of the left and right upper suspension brackets 1 and 2 are connected with the front part of the motorcycle frame 5, and the lower ends are connected with a front mounting hole on the suspension lower bracket 3 and a front mounting hole on the engine front suspension; after the combined structure is connected, the upper suspension bracket, the lower suspension bracket 3, the engine 4 and the frame assembly 5 form a whole, the left upper suspension bracket 1, the right upper suspension bracket 1, the left upper suspension bracket 2 and the lower suspension bracket 3 form a Y-shaped structure when viewed from the front of the vehicle body, the strength of the upper suspension bracket is enhanced by the design structure, the left upper suspension bracket 1 and the right upper suspension bracket 2 are in Y-shaped structures and adjust the stress condition of a front suspension mounting point of the engine to the stress of a left vehicle frame pipe and a right vehicle frame pipe at the middle front part of the vehicle frame by depending on the self shape of the lower suspension bracket 3 and the special shape formed by the upper suspension bracket, the high-frequency vibration generated when the engine operates is well absorbed, the abrasion caused by the vibration impact force generated by the high-frequency vibration of the engine with medium and large displacement on the rear suspension bracket of the vehicle frame is solved, the driving comfort is improved, and on the other hand, the defect generated by excessive positioning of the traditional engine with medium and large Insufficient dynamic and strength.
