The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model and should not be construed as a limitation to the present utility model.

[0018] Please refer to Figures 1 to 3 , in which Figure 1 is the overall structural schematic diagram of the equalizer beam of the large-horsepower crawler bulldozer of the present utility model; Figure 2 is the 3D view of the equalizer beam of the large-horsepower crawler bulldozer of the present utility model; Figure 3 is the sectional view of the equalizer beam of the large-horsepower crawler bulldozer of the present utility model.

[0019] The present utility model provides an equalizer beam for a large-horsepower crawler bulldozer: including an equalizer beam body 101 and a vibration damping component. The vibration damping component includes a frame 102, a mounting seat 103, vibration damping gaskets 104, wear-resistant friction plates 105, vibration damping springs 106, a connecting member and a fixing member. The connecting member includes a pin shaft 107 and a supporting member. The supporting member includes a bearing 109 and an oil seal 110. The fixing member includes a cover plate 111 and bolts 112. Through the foregoing solution, the problem that in the process of using the equalizer beam of a large-horsepower crawler bulldozer, due to the lack of a vibration damping structure on the equalizer beam, it is prone to wear caused by vibration during use, thereby reducing the service life, is solved. It can be understood that the foregoing solution can be used in the scenario of bulldozer use.

[0020] In this embodiment, the vibration damping component is installed on the equalizer beam body 101, so as to reduce the influence of the vibration generated during the operation of the bulldozer on the equalizer beam body 101, thereby improving the service life. The equalizer beam body 101 is welded by two side vertical plates and upper and lower bent plates. The equalizer beam body 101 plays a role in maintaining the balance of the bulldozer. The equalizer beam body 101 is a mature prior art and will not be elaborated in this solution.

[0021] Among them, the mounting seat 103 is fixedly installed on the frame 102, the damping gasket 104 is fixedly installed on the balance beam body 101, the wear-resistant friction plate 105 is fixedly installed on the mounting seat 103, the balance beam body 101 is installed in the mounting seat 103, the connecting member is installed on the balance beam body 101, and the fixing member is installed on the mounting seat 103. The number of the frames 102 is two, and the two frames 102 are respectively located on the bulldozer. Each frame 102 is provided with the mounting seat 103, and the frame 102 supports the mounting seat 103; the mounting seat 103 supports the wear-resistant friction plate 105, the balance beam body 101 and the connecting member, and the mounting seat 103 cooperates with the fixing member to fixedly install the balance beam body 101 on the mounting seat 103; the number of the damping gaskets 104 is two, and the two damping gaskets 104 are respectively located on the balance beam body 101. The damping gasket 104 abuts against the wear-resistant friction plate 105 to play a role in supporting and damping the balance beam body 101; the wear-resistant friction plate 105 supports the damping gasket 104; the connecting member limits the balance beam body 101 on the mounting seat 103; the fixing member fixes the balance beam body 101 on the mounting seat 103; during use, the connecting member is installed on the balance beam body 101, the balance beam body 101 is installed in the mounting seat 103 to make the damping gasket 104 and the wear-resistant friction plate 105 abut against each other, and then the balance beam body 101 is fixed on the mounting seat 103 through the fixing member to complete the installation of the balance beam body 101. When the bulldozer is in use, the abutting and damping of the damping gasket 104 and the wear-resistant friction plate 105 reduce the influence of the vibration generated during the operation of the bulldozer on the balance beam body 101, thereby improving the service life.

[0022] Secondly, the damping spring 106 is installed on the mounting seat 103. Each mounting seat 103 is provided with the damping spring 106, and the damping spring 106 abuts against the top of the balance beam body 101 to further play a role in damping the balance beam body 101.

[0023] Again, the balance beam body 101 has pin holes 108, and the pin shaft 107 is mounted on the pin holes 108 through the support components. The number of the pin holes 108 is two, and the two pin holes 108 are respectively located on the left and right sides of the balance beam body 101, and the pin holes 108 support the support components; the pin shaft 107 is mounted on each of the pin holes 108, and the pin shaft 107 plays a role in connecting and limiting. The mounting seat 103 has a groove, and the groove accommodates the pin shaft 107. When the balance beam body 101 is mounted on the mounting seat 103, the pin shaft 107 is located in the groove, so that the balance beam body 101 is limited on the mounting seat 103, which is convenient for mounting the balance beam body 101 on the mounting seat 103. At the same time, the balance beam body 101 and the mounting seat 103 are closely combined together to form a stable overall structure, and various forces and torques during the driving of the bulldozer are transmitted and dispersed.

The bearing 109 is mounted on each of the pin holes 108, and the oil seal 110 is mounted on each of the bearings 109. The bearing 109 plays a role in supporting, reducing friction and consumption, reducing the friction force between the pin shaft 107 and the balance beam body 101, and reducing power consumption; the oil seal 110 plays a role in preventing external contamination, preventing lubricating oil leakage, and preventing pollutants such as water, chemical liquid medicine, and dust from invading between the bearing 109 and the pin shaft 107, and prolonging the service life; the pin shaft 107 is mounted on the pin hole 108 through the bearing 109 and the oil seal 110, which can make the balance beam body 101 have stability and durability.

[0025] Then, the cover plate 111 is installed on the mounting seat 103, and the bolt 112 is installed on the cover plate 111, penetrating through the cover plate 111 and located within the mounting seat 103.

[0026] When the balance beam of a large - horsepower crawler dozer in this embodiment is in use, the pin shaft 107 is installed on the balance beam body 101 through the bearing 109 and the oil seal 110. The balance beam body 101 is installed within the mounting seat 103, such that the pin shaft 107 is snapped into the groove on the mounting seat 103, the shock - absorbing gasket 104 and the wear - resistant friction plate 105 are in contact, the shock - absorbing spring 106 and the top of the balance beam body 101 are in contact.

When the dozer is in use, through the contact shock absorption of the shock - absorbing gasket 104 and the wear - resistant friction plate 105, and the shock - absorbing effect of the shock - absorbing spring 106, the influence of the vibration generated during the operation of the dozer on the balance beam body 101 is reduced, thereby extending the service life.
