Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle axle technology, specifically a reinforced reducer housing connection structure, applicable to mining truck axles and heavy truck axles. Background Technology
[0002] During vehicle operation, slippage can easily occur between the gearbox housing and the reinforcing ring mating surface, leading to seal failure and oil leakage. Because the vehicle's movement generates significant impacts, the mating surfaces of the gearbox housing and reinforcing ring will move back and forth. Over time, the sealant will fail, causing the lubricating oil inside the gearbox housing to leak, resulting in a malfunction. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a reinforced reducer housing connection structure.
[0004] The technical solution provided by this utility model is: a reinforced reducer housing connection structure, characterized in that it consists of an axle housing body, a reducer housing, a reinforcing ring, connecting bolts, and a fixing pin; a reinforcing ring is provided at the middle position of the axle housing body, and the two are welded together; the end face of the reinforcing ring is provided with a threaded hole and a pin hole, with the threaded hole extending through to the axle housing body; a pin hole is provided on the reducer housing at a position corresponding to the pin hole of the reinforcing ring; the inner end face of the reducer housing and the outer end face of the reinforcing ring are connected; the outer bolt head of the connecting bolt is connected to the bolt hole end face of the reducer housing, and the bolt is threaded into the threaded hole of the axle housing body and the reinforcing ring; the fixing pin is interference-fitted into the pin hole of the reducer housing and the reinforcing ring.
[0005] Furthermore, the fixing pins fix the reinforcing ring and the reducer housing, and there are two fixing pins, which are distributed on opposite sides of the reducer housing.
[0006] Furthermore, the fixing pin, the reinforcing ring, and the hole in the reducer housing are interference-fitted.
[0007] Furthermore, the mating end faces of the reducer housing and the reinforcing ring are provided with sealant.
[0008] Furthermore, the bridge housing body and the outer edge of the reinforcing ring are welded together.
[0009] Furthermore, there are 16 connecting bolts distributed in a circle.
[0010] The beneficial effects of this utility model are as follows: 1. The fixing pin strengthens the connection between the reducer housing and the reinforcing ring, greatly reducing the sliding amount of the mating surface of the reducer housing; 2. The fixing pin has a simple structure and is easy to assemble; 3. The fixing pin is added on the basis of the existing structure without changing the reducer housing structure, only adding two holes, which is easy to implement and highly practical. Attached Figure Description
[0011] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 yes Figure 1 A schematic diagram of the front view structure.
[0012] In the diagram, 1 is the axle housing body; 2 is the reducer housing; 3 is the reinforcing ring; 4 is the connecting bolt; and 5 is the fixing pin. Detailed Implementation
[0013] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.
[0014] like Figure 1 , 2 As shown, a reinforced reducer housing connection structure is composed of a bridge housing body 1, a reducer housing 2, a reinforcing ring 3, a connecting bolt 4, and a fixing pin 5. The reinforcing ring 3 is installed in the middle of the axle housing body 1, and the two are welded together around the outside. Threaded holes and pin holes are machined on the end face of the reinforcing ring 3, with the threaded holes extending through to the axle housing body 1 and the pin holes only on the reinforcing ring 3. Pin holes are also machined at corresponding locations on the reducer housing 2. The inner end face of the reducer housing 2 and the outer end face of the reinforcing ring 3 are connected, and the mating surfaces are sealed with sealant. The outer bolt head of the connecting bolt 4 is connected to the bolt hole end face of the reducer housing 2, and the thread is screwed into the threaded holes on the axle housing body 1 and the reinforcing ring 3. The reducer housing 2 and the reinforcing ring 3 are connected by the connecting bolts 4, which are distributed in a circle of 16. Then, the fixing pin 5 is pressed into the pin holes on the reinforcing ring 3 and the reducer housing 2. The pin holes and the fixing pin 5 are interference fit. There are two fixing pins 5, distributed on opposite sides of the reducer housing 2. This achieves a reinforced connection between the reducer housing 2 and the reinforcing ring 3.
[0015] This utility model is a structure for strengthening the connection of the reducer housing. As long as the fixing pin is not loose or falls off, it can strengthen the connection, prevent oil leakage from the mating surface of the reducer housing, and greatly improve the reliability of the differential housing.
[0016] It should be understood that all technical features not described in detail in this specification belong to the prior art; although the embodiments of this utility model patent have been described, this utility model is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make more forms under the guidance of this utility model without departing from the spirit and scope of protection of this utility model and the claims, and these all fall within the protection scope of this utility model.
