[0002] Traditional loader radiators and hoods are secured together using bolted tie rods. This rigid connection is subject to significant impact, vibration, noise, and maintenance, impacting the stability of the motor drive system and reducing the radiator's service life. Traditional loader radiators require an oblong hole in the tie rod to adjust the mounting distance. Frequent vibration can also cause the bolts in these holes to loosen, leading to connection failure and damage to the radiator or hood. Summary of the Invention

The loader radiator shock absorber has the advantages of good shock absorption, low noise, low maintenance, and high system integration. Furthermore, the shock absorber can be equipped with an adjustable gasket, eliminating the need for an oblong hole in the tie rod, where only a circular hole is required. This helps ensure uniform force distribution across the tie rod and avoids the problem of the oblong hole causing the tie rod to lose its function when the bolt is loosened.

[0021] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] Example 1

[0023] like Figures 1 to 6 As shown, a loader radiator shock absorbing device, the shock absorbing device 2 includes: a mounting block 1 81 for connecting the radiator assembly 1; a mounting block 2 82 for connecting the hood assembly 3; both the mounting block 1 81 and the mounting block 2 82 are equipped with a shaft sleeve shock absorber 10; one end of the pull rod 9 is connected to the mounting block 1 81 through the shaft sleeve shock absorber 10, and the other end of the pull rod 9 is connected to the mounting block 2 82 through the shaft sleeve shock absorber 10.

[0024] The radiator assembly 1 includes a fan 4, a frame 5, a drive motor 6, and other components. The drive motor 6 is mounted on the frame 5 and connected to the mounting block 81. The radiator is vertically fixed to the rear frame. The fan 4, driven by the drive motor 6, cools the hydraulic and transmission oils. The hood assembly 3 is fixed to the rear frame and covers the radiator assembly 1. The hood assembly 3 and the radiator assembly 1 are connected via a shock absorber 2.

[0025] The fan motor can be driven by a hydraulic motor or an electric motor, thereby delivering the speed and torque that meet the fan requirements.

[0026] There is a heat shield between the radiator and the engine. The cooling of the engine does not rely on this radiator. This radiator is only for the hydraulic system.

[0027] The bushing damper 10 is assembled within the mounting block and comprises an outer bushing 101 for connection to mounting block 1 81 or mounting block 2 82; an inner core shaft 102 for connection to the tie rod 9; and an elastic member 103 positioned between the outer bushing 101 and the inner core shaft 102. The inner core shaft 102 and outer bushing 101 are metal, while the elastic member 103 is made of rubber (NR). The bushing damper 10 is connected to the tie rod 9 at both ends to reduce vibration between the radiator assembly 1 and the hood assembly 3. Washers are placed between the tie rod 9 and the bushing damper 10. Bolts, nuts, and washers secure the ends of the tie rod to the bushing damper. Using the bushing damper 10 reduces vibration and extends the life of the radiator.

[0028] The inner core shaft 102 is provided with a slot for connecting the pull rod 9, which is used to limit the pull rod 9. The slot is exposed from the mounting block, so that there is no rigid contact between the pull rod 9 and the mounting block, thereby avoiding a rigid connection between the pull rod 9 and the mounting block.

[0029] The pull rod 9 is symmetrically arranged on both sides of the mounting block one 81 and the mounting block two 82. The pull rod 9 is respectively connected to the shaft sleeve shock absorber 10 at both ends, the shaft sleeve shock absorber 10 is assembled in the mounting block 8, and the mounting block 8 is fastened to the radiator assembly 1 and the hood assembly 3 through bolts. The shaft sleeve shock absorber 10 is provided with a clamping groove at both ends, which avoids the rigid connection of the pull rod 9 and the mounting block 8. The radiator assembly 1 and the hood assembly 3 are assembled on the rear frame, and the upper parts of the radiator assembly 1 and the hood assembly 3 are connected through two shock absorbers 2.

[0030] Adjusting washers 7 are arranged between the shock absorber 2 and the radiator assembly 1 and between the shock absorber 2 and the hood assembly 3. By adjusting the number of the adjusting washers 7, the connecting length of the shock absorber 2 can be changed, the assembly distance can be adjusted, the pull rod 9 has adjustability, and the long circular hole in the pull rod 9 is not needed, so that the connection failure problem of the pull rod after vibration is avoided.

[0031] The present application improves the service life of the radiator and optimizes the driving experience; has the advantages of good shock absorption, low noise, low maintenance rate, high system integration degree, low maintenance cost, high strength, and can reduce the whole machine vibration amount. At the same time, the shock absorber can be assembled with adjusting washers, and only a circular hole is needed, which helps to ensure the uniformity of the force of the pull rod and avoid the problem of the failure of the pull rod due to the loosening of the bolt. It is especially suitable for places with large vibration and high stability requirements.

[0032] Embodiment two:

[0034] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection scope of the present application.
