[0022] like Figure 1-5 As shown, a spring-buffered power output device includes a connecting disk 1 and a transmission seat 2, a spline hole 21 is provided on the transmission seat 2, the axis of the spline hole 21 coincides with the center line of the connecting disk 1, and also includes a side disk 3 and a telescopic member 4, the side disk 3 is fixedly connected to the transmission seat 2, the telescopic member 4 is arranged between the connecting disk 1 and the side disk 3, and the telescopic direction of the telescopic member 4 is parallel to the tangent of the point where the telescopic member 4 contacts the connecting disk 1; a transmission shaft 5 is arranged in the spline hole 21, and the transmission shaft 5 is transmission-connected to a hydraulic pump 6. The power of the flywheel is transmitted to the power transmission device through the connecting disk 1. A telescopic part 4 is arranged between the connecting disk 1 and the side disk 3. When the power is transmitted from the connecting disk 1 to the side disk 3, the telescopic part 4 plays a buffering effect; the side disk 3 is fixedly connected to the transmission seat 2, and the transmission shaft 5 is inserted in the transmission seat 2. The transmission shaft 5 transmits the power to the hydraulic pump 6. Therefore, when the load of the hydraulic pump 6 is too large or the transmission system fails during the power transmission process, the telescopic part 4 plays a buffering protection role to avoid damage to certain components during the transmission process, resulting in reduced reliability of the entire equipment; the telescopic direction of the telescopic part 4 is parallel to the tangent of the point where the telescopic part 4 contacts the connecting disk 1. At this time, the power direction during the rotation of the connecting disk 1 is the same as the telescopic direction of the telescopic part 4. The telescopic part 4 can be used to store and release energy to play a buffering role.
[0023] like Figure 2-5As shown, this embodiment provides a method of 8 telescopic parts 4, and the 8 telescopic parts 4 are evenly arranged on the connecting plate 1, but are not limited to 8. Increasing the number of telescopic parts 4 improves the impact resistance between the connecting plate 1 and the side plate 3, so the number of telescopic parts 4 can be increased or decreased according to actual needs. This embodiment provides a specific structural form in which the telescopic part 4 is a spring. The telescopic part 4 can also be a shrapnel or rubber block that can be retracted and can withstand a certain pressure. The advantage of choosing a spring is that the spring is easy to obtain, the pressure it withstands can be adjusted according to the thickness of the spring, and it includes two ends. Compressing the two ends can transmit and store energy, which is more suitable for our actual production needs.
[0024] The connection disk 1 is provided with a socket hole 12 and a plurality of transmission placement holes 11, the transmission seat 2 is arranged in the socket hole 12, a plurality of the transmission placement holes 11 are arranged around the socket hole 12, and the telescopic member 4 is arranged in the transmission placement hole 11. In order to reduce the volume of the entire device, the transmission seat 2 is arranged in the socket hole 12, saving the radial dimension of the transmission seat 2, but no power is transmitted between the transmission seat 2 and the socket hole 12. At this time, the connection disk 1 rotates around the transmission seat 2, and the transmission seat 2 guides the connection disk 1; the telescopic member 4 is arranged in the transmission placement hole 11, and the power of the connection disk 1 during rotation is transmitted to the telescopic member 4.

The power transmission is more uniform. The containers 33 are arranged on the first side plate 31 and the second side plate 32. The containers 33 on both sides of the transmission placement hole 11 can fix the telescopic member 4 in the transmission placement hole 11 in the transmission placement hole 11, so as to prevent the telescopic member 4 from being separated from the transmission placement hole 11 after being subjected to force, thereby increasing the reliability of the entire device.
[0026] like Figure 2-5As shown, the container 33 includes a container barrel 331, a first container end 332 and a second container end 333.

The container barrel 331 is used to contain the telescopic member 4. During the rotation of the connecting disk 1, power is transmitted to the first container end 332 or the second container end 333. Whether the power is transmitted to the first container end 332 or the second container end 333 is determined according to the rotation direction of the connecting disk 1.
[0027] The first side disc 31 and the second side disc 32 are arranged on the transmission seat 2, and the first side disc 31 and the second side disc 32 are riveted, welded or plugged with the transmission seat 2. The first side disc 31 and the second side disc 32 transmit power to the transmission seat 2, so the first side disc 31 and the second side disc 32 can be connected with the transmission seat 2 by riveting, welding or plugging, and this embodiment provides a specific structural method of riveting.
[0028] The connecting disk 1 is circular and is provided with a mounting ring 13 which is arranged around the circumference of the connecting disk 1. The mounting ring 13 is used to connect with the flywheel. This embodiment provides a threaded connection.
