Embodiment Construction
[0010] Below by embodiment and in conjunction with accompanying drawing, the present invention will be further described:
[0011] like figure 1 The high-torque differential gearbox shown is mainly composed of a casing consisting of a case cover and a casing, and a transmission mechanism inside the casing. The case cover is provided with a power input hole 1 and a power output hole 2, and a transmission shaft is installed in the power input hole 1 and the power output hole 2. Both the case cover and the case body are aluminum castings with light weight, and the case cover and the case body are connected together by six bolts 10 .
[0012] With the power output hole 2 as the center of the circle, a first annular boss 3 and an annular rib 4 are arranged, the first annular boss 3 surrounds the outer periphery of the power output hole 2, and the diameter of the annular rib 4 is larger than the diameter of the first annular boss 3 . With the power output hole 2 as the center of...

The invention relates to a high-torque differential gearbox. A power input hole and a power output hole are formed in a box cover. The power output hole is regarded as the center, a first annular boss, an annular rib and strip ribs which are distributed in a scattered mode are arranged. The inner side of each strip rib is connected with the first annular boss. The outer side ends of the part of the strip ribs extend out of the annular rib, and the outer side ends of the other strip ribs are connected with positioning columns arranged on the annular rib. The number of the strip ribs which are close to the power input hole is more than the number of the strip ribs which are far away from the power input hole. The parts, positioned between the annular rib and the first annular boss, of the strip ribs are in the same plane with the parts of the annular ribs and the first annular boss. The thickness of the parts, positioned outside the annular rib, of the strip ribs is gradually reduced until the strip ribs are flush with the box cover. A second annular boss is arranged in a surrounding mode of the power output hole, and the first annular boss is connected with the second annular boss through a third annular boss. The intensity between the power output hole and the power input hole which are formed in the box cover is enhanced, and the box cover can bear the big torque when the vehicle differential gearbox is in use.
Description
technical field [0001] The invention relates to the technical field of automobiles, in particular to a high-torque differential gearbox. Background technique [0002] The differential transmission is a combined speed change transmission device that is formed by sealing the differential gear train with the basic transmission. By selecting different transmission parameters in the device, it can realize precise speed regulation and expand the carrying capacity of the basic transmission, or Expand the speed range of the basic transmission. [0003] Differential gearboxes currently used in the automotive industry, such as figure 2 As shown, it usually consists of a casing and a transmission mechanism C arranged inside the casing. The shell is composed of a box cover B and a box body A, both of which are castings, and the box cover B is provided with a power input hole 1 and a power output hole 2 . When the automobile differential transmission is working, both the box body A an...
