  • Forklift Steer Axle
    Forklift Steer Axle Forklift Steer Axles - The description of an axle is a central shaft for rotating a gear or a wheel. Where wheeled vehicles are concerned, the axle itself could be fixed to the wheels and revolve together with them. In this instance, bearings or bushings are provided at the mounting points where the axle is supported. Conversely, the axle can be connected to its surroundings and the wheels can in turn revolve around the axle. In this particular instance, a bearing or bushing is situated inside the hole within the wheel in order to enable the wheel or gear to rotate around the axle. With trucks and cars, the word axle in several references is utilized casually. The term generally refers to the shaft itself, a transverse pair of wheels or its housing. The shaft itself rotates together with the wheel. It is frequently bolted in fixed relation to it and referred to as an 'axle shaft' or an 'axle.' It is equally true that the housing around it that is normally known as a casting is likewise called an 'axle' or occasionally an 'axle housing.' An even broader definition of the word means every transverse pair of wheels, whether they are connected to one another or they are not. Hence, even transverse pairs of wheels inside an independent suspension are generally known as 'an axle.' The axles are an important component in a wheeled motor vehicle. The axle serves in order to transmit driving torque to the wheel in a live-axle suspension system. The position of the wheels is maintained by the axles relative to one another and to the motor vehicle body.

Barve5 [1,2,3,4] B.E. Student, Department of Mechanical Engineering, SavitribaiPhule Pune University, Pune, India [5] Professor, Department of Mechanical Engineering, Savitribai Phule Pune Universitym Pune, India Abstract Earlier, FS cars used to have independent suspension system which involved chassis and differential system. Our solid axle system provides a dependent suspension system consisting of less number of moving components and reduced weight of the system. This is achieved by designing a single component capable of performing all the operations that a chassis and differential system can perform. The design is further simplified by removing constant velocity joints and tripod assemblies. This component results in an increase in reliability, effectiveness as well as efficiency and further reduces cost of the system.

In this system a lateral over rough patches, yet responsive enough to quick connection by a single beam or a shaft is made with the driver inputs. The drivers will be able to focus more on wheels. In FS competitions track surfaces are flat. the track, and not worry about the car’s behavior.

  • Multi-Criteria Optimization of an Innovative Suspension System for Race Cars
    applied sciences Article Multi-Criteria Optimization of an Innovative Suspension System for Race Cars Vlad T, ot, u and Cătălin Alexandru * Product Design, Mechatronics and Environment, Transilvania University of Bra¸sov, Bulevardul Eroilor 29, 500036 Bra¸sov, Romania; [email protected] * Correspondence: [email protected]; Tel.: +40-724-575-436 Abstract: The purpose of the present work was to design, optimize, and test an innovative suspension system for race cars. The study was based on a comprehensive approach that involved conceptual design, modeling, simulation and optimization, and development and testing of the experimental model of the proposed suspension system. The optimization process was approached through multi-objective optimal design techniques, based on design of experiments (DOE) investigation strategies and regression models. At the same time, a synthesis method based on the least squares approach was developed and integrated in the optimal design algorithm. The design in the virtual environment was achieved by using the multi-body systems (MBS) software package ADAMS, more precisely ADAMS/View—for modeling and simulation, and ADAMS/Insight—for multi-objective optimization. The physical prototype of proposed suspension system was implemented and tested with the help of BlueStreamline, the Formula Student race car of the Transilvania University of Bras, ov. The dynamic behavior of the prototype was evaluated by specific experimental tests, similar to those the single seater would have to pass through in the competitions. Both the virtual and experimental results proved the performance of the proposed suspension system, as well as the usefulness of the design algorithm by which the novel suspension was developed.

  • Analysis and Optimization of the Double-Axle Steering Mechanism with Dynamic Loads
    26 The Open Mechanical Engineering Journal, 2012, 6, (Suppl 1-M2) 26-39 Open Access Analysis and Optimization of the Double-Axle Steering Mechanism with Dynamic Loads Gang Qin, Ying Sun, Yunqing Zhang* and Liping Chen Center for Computer-Aided Design, School of Mechanical Science & Engineering, Huazhong University of Science and Technology, Wuhan, Hubei 430074, P.R. China Abstract: A hierarchical optimization procedure for the optimal synthesis of a double-axle steering mechanism used in truck with dynamic loads is presented. A multibody model of double-axle steering mechanism is presented to characterize the leaf spring effect. The influences of dynamic loads, the motion interference of steering linkage resulted from the elastic deformation of leaf spring, and the effects of wheel slip angles and the position discrepancies of wheel speed rotation centers are studied systematically. A hierarchical optimization method based on target cascading methodology is proposed to classify the design variables of double-axle steering mechanism into four levels. A double-axle steering mechanism for a heavy-duty truck is utilized to demonstrate the validity of the proposed method. The simulation results indicate that the hierarchical optimization procedure is effective and robust. And as a result, it will surely be widely used in engineering.

Focus was to make the front suspension of the vehicle lighter than the double wishbone setup yet it retains the characteristics of unequal double wishbone setup which may not be possible through MacPherson strut type of suspension setup. The overall carbon footprint for the vehicle is lower hence keeping it eco-friendlier. This vehicle has lesser components than a typical ATV implying that manufacturing and production costs are reduced. Therefore, the vehicle is cheaper than any other all-terrain vehicle. Keywords- suspension modeling , double wishbone, design optimization. 1) Introduction This paper in particular concentrates on the design of the suspension for an ATV, modifying the mounting factors, analysing of the forces that are to be damped with the aid of the suspension. Suspension gadget plays a vital role within the coping with of the vehicle. It allows the driver to manoeuvre the vehicle. The main feature of suspension is to ensure that the driver feels snug while riding the auto and the forces are damped to save you chassis from getting damaged.

  • Complete Chassis Instruction Sheet for 1932 Ford
    Caster is the backward or forward tilt of the kingpin about which the spindle pivots for steering. This tilt or caster angle is measured in degrees by the amount the centerline of the What is Caster? kingpin is tilted from true vertical. A backward tilt at the top of the kingpin is called positive caster. A forward tilt is known as negative caster. Because caster is a directional Complete Chassis control setting, tilting the kingpin toward a positive caster angle gives the front wheels the tendency to go straight ahead which also influences the steering wheel to return to a straight ahead position after a turn. With a negative caster setting the steering wheel of the vehicle becomes very Instruction Sheet For touchy and harder to control as speed is increased. The tires have a tendency to pull to one side or the other causing the car to wander and weave. Understanding that caster angle influences the directional 1932 Ford control of the wheel, you can then see that a different caster angle for each front wheel will create an uneven steering effect. This unequal caster will be noticeable to the driver as the car will want to pull toward the side having the least positive (or most negative) caster angle. A solid type axle would be thought to have equal caster on both ends of the axle, but this is not always the case. If the axle is a custom fabricated tube type the responsibility of the caster angle being equal belongs to the manufacturer and the accuracy of his axle fixtures.

The axle on wheeled motor vehicles could be attached to the wheels and turned with them.

On the other hand, the axle may be connected to its surroundings and the wheels may in turn rotate around the axle.
