Problems solved by technology
The disadvantages of friction self-locking differential locking are: complex structure, high processing requirements, large wear of friction parts, and high cost
The disadvantage of this kind of differential lock is that it needs a large speed difference between the left and right axles, which is not suitable for the slow speed situation; it takes time for the silicone oil to cool down after locking, and it cannot be disengaged quickly
[0006] The forced locking differential is to set a differential lock on the ordinary symmetrical bevel gear differential. Its disadvantage is that it is inconvenient to operate. Generally, it needs to stop. If the differential lock is connected too early or taken off too late, it will cause Phenomenon without differential, torque distribution is not variable

Embodiment Construction
[0041] The present invention will be further described below with reference to the accompanying drawings.
[0042] see Figure 1 to Figure 13 .
[0043] like figure 1 Shown is a differential locking device for a power-assisted road cutting machine according to the present invention, comprising a left half shaft (2), a push rod (3), a shifting fork (4), a locking disc (5) (such as figure 2 , image 3 , Figure 4 ), locking gear (6) (such as Figure 5 , Image 6 , Figure 7 ), left shell (7) (such as Figure 11 ), right shell (8) (such as Figure 12 ), right half shaft (12), differential bevel gear combination (14), spring (15), feather key bushing (16) (such as Figure 8 , Figure 9 ).
[0044] The left casing (7) and the right casing (8) are fastened with bolts to form the outer casing of the differential transmission device. Disc (5), locking gear (6), left end of right half shaft (12), differential bevel gear combination (14), spring (15), feather key bushing (1...

The invention relates to a differential locking device for power-assisted traveling pavement cutting machines. The differential locking device comprises a left case, a right case, a left half shaft, a right half shaft, a push rod, a shift fork, a locking disc, a locking gear, a differential bevel gear combination, a spring and a feather key shaft sleeve, wherein the left and right cases are in fastening connection through a bolt; the differential bevel gear combination and the locking gear are in fastening connection; a combination body of the differential bevel gear combination and the locking gear as well as the locking disc, the left half shaft and the right half shaft form a power transmission part of the differential; and the locking disc and the locking gear form a clutch together, and the locking disc can slide on the feather key shaft sleeve left and right, so that meshing and separation of the locking disc and the locking gear, that is, locking and free differential of the differential are realized. The differential locking device is simple in structure, convenient to manufacture and use, capable of effectively locking the differential and applicable to differential locking of the power-assisted traveling pavement cutting machines for buildings, squares, roads and bridges.
Description
technical field [0001] The invention relates to a differential locking device for a power-assisted walking road cutting machine, which is a differential locking device for a power-assisted walking road cutting machine suitable for buildings, squares, highways and bridges. Background technique [0002] At present, the commonly used differential locking methods for vehicles include Torsen (Torsen) double worm gear locking mechanism, high friction self-locking locking mechanism, viscous coupling locking mechanism, forced locking differential and so on. [0003] Torsen's double worm gear and worm lock structure realizes the differential locking function based on the structure of intermeshing and interlocking and the torque is transmitted from the worm gear to the worm gear in one direction. It is widely used in the center differential of all-wheel drive cars. And the rear transaxle inter-wheel differential. Due to its automatic locking effect at high speed and torque difference...
