Design and fabrication of wheel removing machine

The proposed system's basic premise is to reduce personnel during nut fitting and removing wheels from autos. The motor is at the heart of the project and its implementation. Motor, Nut fitting arrangement (multi nut remover), and spur gear arrangement are the components employed here for the efficient operation of separate blocks. The model's main goal is to remove all of a wheel's nuts at once, rather than one by one. The model's premise is to use a spur gear to transfer relative motion to other gears. The primary spur gear is connected to the motor shaft in the model, which rotates due to the motor. The primary gear is the driver, while the secondary gears are the driven. The major gear is located in the model's center. The secondary gears and the primary gear are in sync. To ensure precise meshing and tool spacing, the secondary gears are set at predetermined distances. The drive axle is equipped with primary gear. The cover has several auxiliary axles that extend through it. Each secondary axle has a first end that is positioned inside the housing and a second end that extends outwardly from the cover. One of the first ends is attached to each of several secondary gears. Each of the secondary gears is in contact with the primary gear. One of the secondary axles is connected to each of the couplers. The project and implementation must provide the motor with both positive and negative potential. If we press the corresponding switch for forwarding rotation, the nut will be fixed; if we press the corresponding switch for reverse rotation, the polarity will be reversed, and the nut will be removed. The motor can be controlled according to the needs of the operator. To tighten or remove the nut, the operator should lift the model and place it in the proper location.

Finite-Element Analysis on Lightweight Material of Drive Axle Housing

In actual engineering, the drive axle of vehicles is often enlarged to prevent it from being damaged. However, the enlargement will increase the weight of the vehicle, pushing up fuel consumption and exhaust emissions. This common practice is obviously detrimental to the environment and sustainable development. To meet the stiffness and strength requirements on the drive axle housing of Steyr heavy trucks, this paper carries out finite-element analysis on the stiffness and strength of the axile housing under different working conditions, in the light of its actual stress features. According to the production process of drive axle housing in truck, the authors reviewed the development of the materials for high-strength axle housing, which could be properly formed through hot stamping, cold stamping, and mechanical expansion, and briefly introduced the structural features of drive axle housing. Then, a drive axle model was established in the three-dimensional (3D) drawing software Pro/ENGINEER, and converted into a finite-element model in Pro/Mechanica by calling the meshing command. On this basis, the static load of axle housing was analyzed under four working conditions: maximum vertical force, maximum traction, maximum braking force, and maximum lateral force. Finite-element analysis was performed on the meshed model to obtain the displacement and stress cloud maps of the axle housing under each working condition. The results show that the drive axle housing satisfy the requirements on strength, stiffness, and deformation. To sum up, this research improves the design efficiency and quality of products through finite-element analysis on the stiffness and strength of drive axle housing.

Material comparison of dynamic cornering fatigue test (iso3006) for automotive wheel rim

With the technological advancement in the automotive sector, the vehicles are crossing their limits in every aspect. Hence, the subsequent improvement related to the wheel and braking of the vehicle is very crucial as the wheel carries the whole weight of the vehicle in dynamic and harsh environmental conditions. ISO-3006 is a comprehensive test for wheel standardization, and the dynamic cornering fatigue test is a part of this standard. This test investigates the wheel fatigue under bending torque. When a car turns, the bending moment is applied to the wheel via drive axle. In this paper, we investigate the test on a designed wheel with five different materials via ANSYS software. As the wheel weight has a direct impact on vehicle performance, selecting lighter materials is extremely important. The result of this research indi-cates the area of maximum fatigue stresses, and also it provides a comparison between five popular materials for the wheel rim considering the fatigue life and weight of the wheel. Finally, it is shown that carbon fiber reinforced plastic (CFRP) has the most fatigue strength con-cerning its lightweight.
