Description

Technical Field

[0001] The utility model relates to the technical field of tractor drive axles, in particular to a product-bearing tractor drive axle with a shock-absorbing structure. Background Art

[0002] A tractor is a vehicle used to assist in the transfer of materials during the factory production process. It is a device that ultimately transmits the input power to the drive wheels, thereby maintaining the tractor's movement.

When the forklift drive axle body vibrates during use, the connecting seat is pressed down by force and the shock-absorbing pad and the multiple groups of pressure-reducing balls inside the shock-absorbing pad are used to achieve initial shock-absorbing and buffering of the impact force. At the same time, the movable plate continues to press down and drives the upper sleeve to move in the lower sleeve. The upper sleeve synchronously squeezes the shock-absorbing spring, so as to further absorb and weaken the vibration force under the action of the shock-absorbing spring and the damping pad, thereby reducing the hard damage to the forklift drive axle body, so as to improve the protection of the forklift drive axle body and extend its service life.

[0004] The drive axle is provided with two sets of fixing hoops, and the upper end of the connecting seat can be installed on the drive axle body. However, the two sets of fixing hoops provided in the device are only connected by the mounting block. Before the positioning pin is not inserted into the mounting block, the two sets of fixing hoops cannot be fixed on the drive axle body, and the fixing hoops need to be manually lifted, which makes the installation of the fixing hoops inconvenient.

[0027] A drive axle for a product-carrying tractor with a shock-absorbing structure comprises: a drive axle body 1;

[0028] A mounting groove 11 is provided on the surface of the driving axle body 1, and a clamping groove 12 is provided on the inner wall of the mounting groove 11;

[0029] A positioning structure 2 is installed on the drive axle body 1, and the positioning structure 2 includes a first hoop plate 21, which is installed at the bottom end of the installation groove 11, and the rear end of the first hoop plate 21 is movably connected to the second hoop plate 26 through a hinge 22, and the side walls of the first hoop plate 21 and the second hoop plate 26 are movably installed with a mounting block 23 through a thread, and a clamping block 24 is slidably installed on the inner side of the mounting block 23, and a first spring 25 is fixedly connected to the surface of the clamping block 24, and the front ends of the first hoop plate 21 and the second hoop plate 26 are fixedly connected by bolts 27, and the first hoop plate 21 and the second hoop plate 26 are connected together by the hinge 22, and the first hoop plate 21 and the second hoop plate 26 can be pre-fixed on the drive axle body 1 through the cooperation of the clamping block 24 and the clamping groove 12, so that the further fixing of the first hoop plate 21 and the second hoop plate 26 on the drive axle body 1 is more convenient and labor-saving.

[0030] Furthermore, a shock absorbing mechanism 3 is installed on the drive axle body 1, and the shock absorbing mechanism 3 includes a connecting rod 35, which is fixedly connected to the bottom surface of the first hoop plate 21, an outer cylinder 32 is sleeved on the outer side of the bottom end of the connecting rod 35, and a hollow groove 33 is opened at the bottom end of the side wall of the outer cylinder 32, and a threaded sleeve 34 is threadedly connected to the outer wall of the outer cylinder 32. A second spring 36 is fixedly connected to the bottom surface of the connecting rod 35, and a mounting rod 31 is fixedly connected to the bottom surface of the outer cylinder 32. The threaded sleeve 34 is rotated so that the threaded sleeve 34 rises on the outside of the outer cylinder 32, so that the inside of the hollow groove 33 can be exposed, so that the debris on the inside of the outer cylinder 32 can be cleaned through the hollow groove 33 to ensure the use effect of the second spring 36.

[0031] Furthermore, the first hoop plate 21 and the second hoop plate 26 are annularly sleeved on the outside of the mounting groove 11 , and the positioning structure 2 can be installed on the drive axle body 1 through the first hoop plate 21 and the second hoop plate 26 .

[0032] Furthermore, the surface of the mounting block 23 is flush with the side walls of the first hoop plate 21 and the second hoop plate 26 , and the mounting block 23 provides support for the installation of the clamping block 24 in the first hoop plate 21 and the second hoop plate 26 .

[0033] Furthermore, the outer end of the block 24 is inserted into the inside of the slot 12, and one end of the first spring 25 is fixedly connected to the inner wall of the block 24. The block 24 cooperates with the slot 12, so that the first hoop plate 21 and the second hoop plate 26 can be pre-fixed in the installation slot 11, which is convenient for the user to rotate the bolt 27 to facilitate the installation of the positioning structure 2.

[0034] Furthermore, the threaded sleeve 34 is sleeved on the outside of the empty groove 33, and one end of the second spring 36 is fixedly connected to the inner wall of the outer cylinder 32. The threaded sleeve 34 can shield the empty groove 33 from the outside, so that the threaded sleeve 34 can be lifted up when needed to clean up the debris inside the outer cylinder 32.

[0035] Working principle: During installation, the top end of the first hoop plate 21 is clamped inside the bottom end of the installation groove 11, and the second hoop plate 26 is pulled so that the second hoop plate 26 is turned over on the first hoop plate 21 through the hinge 22, so that the second hoop plate 26 is clamped inside the upper end of the installation groove 11. At this time, the clamping block 24 on the first hoop plate 21 and the second hoop plate 26 will be clamped on the inner side of the hinge 22 under the action of the first spring 25, so that the first hoop plate 21 and the second hoop plate 26 are pre-fixed in the installation inside the installation groove 11. At this time, it is only necessary to rotate the bolt 27 to connect and fix the first hoop plate 21 and the second hoop plate 26 away from the hinge 22, so that the first hoop plate 21 and the second hoop plate 26 can be installed on the drive axle body 1;

[0036] When in use, the vibration on the drive axle body 1 can be reduced through the cooperation of the damping pad and the second spring 36. By rotating the threaded sleeve 34, the threaded sleeve 34 rises outside the outer cylinder 32, so that the inside of the empty groove 33 can be exposed, which makes it easy to clean the debris inside the outer cylinder 32 through the empty groove 33 to ensure the use effect of the second spring 36.
