Problems solved by technology
Most light crawler tractors adopt the structure disclosed in the patent document with publication number CN1500048A, which includes components such as frame, engine and gearbox. The engine and components are fixedly installed on the overall frame, and the installation accuracy is good. When the tractor is working, the engine and gearbox will generate a lot of vibration, and the vibration force acts on the rigidly connected frame, which has a certain impact on the safety, comfort and service life of the personnel on board.
There are also some manufacturers who design to install elastic damping components at the connection between the frame and the engine, but this elastic damping component can only play the role of vertical shock absorption, and cannot well limit the vibration of the engine and gearbox in the horizontal direction. The displacement of the drive shaft tube of the rear-end gearbox and the connection part of the frame will be damaged

Embodiment 1
[0031] Example 1, such as figure 1 , figure 2 , image 3 and Figure 4 Shown: an upper and lower frame damping structure suitable for light crawler tractors, including a frame, the frame includes an upper frame 1 for connecting the engine, a gearbox and a driving console and is located below the upper frame 1 and used The upper frame 1 and the lower frame 2 are connected to the lower frame 2 connected to the crawler walking part, and the upper frame 1 and the lower frame 2 are connected by a shock absorber 3. The shock absorber 3 includes a position located at the front of the frame, which is close to the engine, and provides horizontal, left, and right directions and vertical directions. The shock-absorbing device 4 of the shock-absorbing effect and the rear shock-absorbing device 5 positioned at the rear of the frame, that is, close to the position of the gearbox and providing horizontal, front-rear and vertical shock-absorbing effects.

The invention relates to the field of mechanical devices, in particular to an upper-and-lower-frame damping structure suitable for a light caterpillar tractor. According to the technical scheme, the upper-and-lower-frame damping structure comprises a frame, the frame comprises an upper frame and a lower frame, the upper frame is used for being connected with an engine, a gearbox and a drive control board, and the lower frame is located below the upper frame and connected with the walking part of a caterpillar track. The upper frame is connected with the lower frame through a damping device. According to the upper-and-lower-frame damping structure suitable for the light caterpillar tractor, under the condition that cost is not increased, the engine is accurately located in installation, when vibration is large or large horizontal force is exerted, the possibility that the engine moves leftwards and rightwards is reduced, and influence of operation vibration of the engine on the frames and an operator is reduced.
Description
technical field [0001] The invention relates to the field of mechanical equipment, in particular to an upper and lower frame damping structure suitable for light crawler tractors. Background technique [0002] As a common production machinery and equipment, light crawler tractors are widely used in agricultural production activities. Most light crawler tractors adopt the structure disclosed in the patent document with publication number CN1500048A, which includes components such as frame, engine and gearbox. The engine and components are fixedly installed on the overall frame, and the installation accuracy is good. When the tractor is working, the engine and gearbox will generate a lot of vibration, and the vibration force acts on the rigidly connected frame, which has a certain impact on the safety, comfort and service life of the personnel on board. There are also some manufacturers who design to install elastic damping components at the connection between the frame and t...
