The invention relates to the technical field of carrier suspension, and discloses a land leveler rear axle balance box which is characterized in that a transmission disc is fixedly mounted at the position, located in the balance box, of the outer surface of a power output shaft, a shaft hole is formed in the position, close to one end, of the outer surface of the balance box, and a bearing II is fixedly sleeved with the shaft hole; a wheel shaft is fixedly sleeved with an inner ring of the bearing II, and a driven wheel is fixedly installed at the position, close to one side of the outer surface of the balance box, of one end of the wheel shaft. A balance wheel is fixedly installed at the position, close to one side of the outer surface of the balance box, of one end of the power output shaft, and the outer surfaces of the driven wheel and the balance wheel are movably sleeved with a crawler belt, so that the driven wheel and the balance wheel in the device can drive the crawler belt to rotate at the same time, and the middle position of the crawler belt can be supported by adopting a three-wheel transmission mode; the wheel tread is greatly reduced, and the deformation quantity of the crawler belt is reduced, so that the problem that the crawler belt is damaged due to collision with a vehicle body when passing through an obstacle is avoided, and the service life of the device is prolonged.
Description
technical field [0001] The invention relates to the technical field of vehicle suspension, in particular to a balance box of a rear axle of a motor grader. Background technique [0002] The balance box is a very common transmission box in engineering vehicles. It is commonly used in various engineering vehicles such as excavators, demolition machines, and graders that need to drive on uneven roads. It consists of a wheel, a transmission chain and a driven wheel. When in use, the power output shaft drives the driving wheel to rotate, and then drives the driven wheel to rotate through the transmission chain. The driven wheel outputs torque to the driving wheel, and the driving wheel drives the crawler to rotate, so as to realize driving The engineering vehicle moves as a whole. The balance box of this structure has the advantages of simple structure, convenient maintenance and low price. It is the most widely used balance box at present. [0003] Although the existing balance...
