AI Technical Summary
The existing excavator loader drive axle housing arm is heavy and has poor heat dissipation because the brake pad mounting area has not been weighted down, which affects braking efficiency.
Ten weight-reducing grooves are set on the circumferential surface of the brake pad mounting base, and reinforcing ribs are added in key parts to form a petal-shaped structure, increasing the exposed area to improve heat dissipation. At the same time, reinforcing ribs are added in parts subjected to large shear forces to ensure strength.
It achieves weight reduction of the axle housing arm, reduces material costs, improves heat dissipation and braking efficiency, and has a simple structure and long service life.

Description
TECHNICAL FIELD
[0001] The utility model relates to excavator drive axle bridge shell technical field, concretely relates to excavator drive axle weight reduction type bridge shell arm. BACKGROUND
[0002] The bridge shell of excavator drive axle generally adopts three sections, mainly comprises bridge shell package and two bridge shell arms, the present bridge shell arm does not make weight reduction treatment to brake pad installation part, causes that the whole bridge shell arm is heavy, the heat dissipation is poor because the exposed area is less at the place, causes that the temperature is too high at the position after long -term work, thereby reduces the brake efficiency. SUMMARY
[0003] The utility model discloses a simple structure, light in weight, low in manufacturing cost, good in heat dissipation effect, high in brake efficiency excavator drive axle weight reduction type bridge shell arm.
[0004] To realize above -mentioned purpose, the utility model excavator drive axle weight reduction type bridge shell arm including axle head 1, bridge pipe 2, brake pad mounting seat 3 and reinforcing rib 6, bridge pipe 2 one end connects axle head 1, the other end connects brake pad mounting seat 3, the side end of this axle head 1 is equipped with fixed bolt hole 4 for connecting drive axle wheel edge assembly, the side end of brake pad mounting seat 3 is equipped with fixed bolt hole 4 for connecting the bridge shell package of drive axle, the circumferential surface of brake pad mounting seat 3 is equipped with ten weight reduction grooves 5, makes the whole brake pad mounting seat 3 present petal shape, the weight reduction groove 5 is located between every two fixed bolt hole 4, wherein is not equipped with weight reduction groove 5 at the vertical axis upper side and lower side two places, the transition of bridge pipe 2 and brake pad mounting seat 3 is equipped with eight reinforcing rib 6, is equipped with a strip at the vertical axis upper side, lower side and the two sides of horizontal axis of brake pad mounting seat 3 respectively, and is equipped with a strip at the two adjacent weight reduction groove 5 of vertical axis upper side and lower side.
[0005] The above-mentioned excavator drive axle weight reduction type bridge shell arm reduces the material cost by optimizing the weight of the bridge shell arm, and improves the heat dissipation effect, which has the following technical features and beneficial effects:
[0006] 1. By evenly setting ten weight reduction grooves 5 on the circumferential surface of the brake pad mounting seat 3, the weight of the bridge shell arm can be reduced, and the material and manufacturing cost can be reduced.
[0007] 2. Because the shear force on the bolt holes at the upper and lower ends of the brake pad mounting seat 3 is large, no weight reduction groove 5 is provided at these two places, and three reinforcing ribs 6 are provided on the upper and lower sides to ensure the strength of these two places.
[0008] 3. The setting of the weight reduction groove 5 and the reinforcing rib 6 increases the exposed area of the brake pad mounting seat 3, which can effectively improve the heat dissipation and the brake efficiency after long time work.
[0009] 4、 The structure is simple and compact, the manufacturing cost is low, the operation is safe and reliable, and the service life is long. BRIEF DESCRIPTION OF DRAWINGS

[0011] Fig. 2 is another side three-dimensional structure schematic diagram of the excavator drive axle weight-reducing axle housing arm.
[0012] Fig. 3 is an axle head side view structure schematic diagram of the excavator drive axle weight-reducing axle housing arm.
[0013] The axle head 1, axle pipe 2, brake pad mounting seat 3, fixed bolt hole 4, weight-reducing groove 5, and reinforcing rib 6 are denoted by reference numerals. DETAILED DESCRIPTION
[0014] The specific embodiments of the excavator drive axle weight-reducing axle housing arm of the utility model will be further described in detail below in combination with the drawings.
[0015] Figs. 1-3 The excavator drive axle weight-reducing axle housing arm of the utility model comprises an axle head 1, axle pipe 2, brake pad mounting seat 3, and reinforcing rib 6, one end of the axle pipe 2 is connected to the axle head 1, and the other end is connected to the brake pad mounting seat 3, the side end of the axle head 1 is provided with a fixed bolt hole 4 for connecting a drive axle wheel edge assembly, the side end of the brake pad mounting seat 3 is provided with a fixed bolt hole 4 for connecting a drive axle housing cover, the circumferential surface of the brake pad mounting seat 3 is provided with ten weight-reducing grooves 5, so that the entire brake pad mounting seat 3 is petal-shaped, the weight-reducing grooves 5 are located between every two fixed bolt holes 4, and the weight-reducing grooves 5 are not arranged at the upper side and lower side of the vertical axis, the transition of the axle pipe 2 and the brake pad mounting seat 3 is provided with eight reinforcing ribs 6, one reinforcing rib 6 is arranged at the upper side, lower side, and both sides of the horizontal axis of the brake pad mounting seat 3, and one reinforcing rib 6 is arranged at the adjacent weight-reducing grooves 5 on the upper side and lower side of the vertical axis.
[0016] The excavator drive axle weight-reducing axle housing arm of the utility model can obviously reduce the weight of the axle housing arm, the shear force of the bolts at the upper end and lower end of the brake pad mounting seat 3 is large, therefore, the weight-reducing grooves 5 are not arranged at the two positions, three reinforcing ribs are arranged on the upper side and lower side to ensure the strength of the two positions, the weight-reducing grooves 5 and reinforcing ribs 6 increase the exposed area of the brake pad mounting seat 3, can effectively improve the heat dissipation and the braking efficiency after long-time work.
