AI Technical Summary
Due to the unstable quality during welding and difficult processing, existing engine rear brackets are prone to cracks or fractures, resulting in short service life.
The casting of the whole cast bracket is made of ductile iron material. Through the high strength and rigidity of the ductile iron and the design of weight reduction holes, a lightweight and high-strength engine cast bracket is formed.
The service life of the rear bracket of the engine is improved, and the quality instability and processing difficulties are avoided due to welding. At the same time, the design of the weight reduction holes releases stress to ensure the stability and safety of the engine and gearbox.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mining vehicle components, in particular to an integral casting bracket for the engine of a non-road wide-body vehicle. Background Art
[0002] Non-road wide-body dump trucks are widely used in mining areas. The road surface environment in mines is harsh. During the operation of vehicles, the frame and various system components are all subjected to large alternating loads, and the handling stability and ride comfort of the vehicles are poor. The engine bracket of a non-road wide-body vehicle is one of the important assemblies of a mining vehicle, and the structure of the engine bracket plays a crucial role in the whole vehicle.
[0003] At present, the existing engine rear bracket on the market is a welded part. Due to the influence of the actual material structure of the welding area during the welding process, there are problems such as greater processing difficulty, poor quality stability, and unattractive welded parts in the welded part. In actual use, cracks or even fractures are likely to occur near the welding, thus reducing the service life of the engine rear bracket. Summary of the Invention
[0004] The utility model provides an integral casting bracket for the engine of a non-road wide-body vehicle to overcome the deficiencies of the prior art.
[0005] The technical solution adopted by the utility model is: an integral casting bracket for the engine of a non-road wide-body vehicle, including a long strip-shaped plate-like body. At both ends of the front surface of the long strip-shaped plate-like body, there are respectively an engine connection plate and a gearbox connection plate. A frame connection seat vertically protrudes from the back surface of the long strip-shaped plate-like body; the frame connection seat includes a mounting plate, a first reinforcing rib plate, and a second reinforcing rib plate. The mounting plate is horizontally arranged along the length direction of the long strip-shaped plate-like body. The first reinforcing rib plate is vertically arranged above both ends of the mounting plate, and the second reinforcing rib plate is horizontally arranged on both sides of the first reinforcing rib plate; there are two arc connection ports on the mounting plate.
[0006] Connection holes are provided at the four corners of the engine connection plate and the gearbox connection plate, and a relief through hole is provided in the center.
[0007] A row of weight-reducing holes is provided along the length direction on the long strip-shaped plate-like body, and the weight-reducing holes are located below the frame connection seat.
[0008] The integral casting bracket is integrally cast and formed by ductile iron.
[0009] Compared with the prior art, the utility model has the following beneficial effects:
[0010] This utility model is integrally formed by casting ductile iron, with a light weight. It avoids the problems of unstable quality, high processing difficulty, and cracks or even fractures caused by welding in the prior art, improving both the service life of the engine rear bracket and simplifying the processing. By setting weight-reducing holes, the weight is reduced while a certain amount of stress is released. Ductile iron has high strength and rigidity, capable of withstanding large loads and impact forces, ensuring the stability and safety of the engine and transmission. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] An integrally cast bracket for an off-road wide-body vehicle engine includes a long strip-shaped plate-like body 1. At both ends of the front surface of the long strip-shaped plate-like body 1, there are respectively an engine connection plate 2 and a transmission connection plate 3. On the back surface of the long strip-shaped plate-like body 1, there is a vertically protruding frame connection seat 4. The frame connection seat 4 includes a mounting plate 4-1, a first reinforcing rib plate 4-2, and a second reinforcing rib plate 4-3. The mounting plate 4-1 is horizontally arranged along the length direction of the long strip-shaped plate-like body 1. The first reinforcing rib plate 4-2 is vertically arranged above both ends of the mounting plate 4-1. The second reinforcing rib plate 4-3 is horizontally arranged on both sides of the first reinforcing rib plate 4-2. There are two arc connection ports 8 on the mounting plate 4-1.
[0015] Connection holes 6 are provided at the four corners of the engine connection plate 2 and the transmission connection plate 3, and a relief through-hole 5 is provided in the center of each.
