Sp057 Leaf Spring Installation
SP057 LEAF SPRING INSTALLATION Also covering Part #RH015 1967-1969 CAMARO AND FIREBIRD NOTE: This part number is designed to use the original mounting hardware from a factory multi-leaf rear end setup. If you have a factory mono-leaf rear end or wish to upgrade the hardware for your multi-leaf setup, you can purchase the BMR leaf spring installation kit (Part #RH015). This kit includes new front mounting hardware, polyurethane leaf spring pads, larger U-bolts, and a heavy duty rear shackle kit with polyurethane frame bushings. INSTALLATION: 1. Lift vehicle and support with jack stands under the frame rails. 2. Remove the lower shock bolts. 3. Loosen the (4) nuts on the shock mounting plates then remove the plates. 4. Place a hydraulic jack under the axle. Lift the axle off the springs. 5. Loosen the nut on the rear lower shackle plates but do not remove the bolt. 6. Loosen the (3) bolts on the front leaf spring pocket and also remove the rear leaf spring bolt then remove the leaf spring from the vehicle. 7. If the vehicle was originally equipped with mono-leaf springs, knock out the factory bolts from the leaf spring axle mount (4 per side). Using a ½” drill bit, drill out the 4 holes in the leaf spring axle mounts. Also drill out the holes in the shock mounts to allow the use of ½” U-bolts. (IMAGE 1) 8. If you also purchased the leaf spring installation kit (RH015), replace the nut clips in the frame at this time. 9. If you purchased the leaf spring installation kit, knock out the upper bushings in the frame and install the supplied polyurethane bushings and inner steel sleeves. -
What You Need to Know About Mounting Radial Tires on Classic Vehicle Rims
What You Need to Know About Mounting Radial Tires on Classic Vehicle Rims Over the past 100 years, tires, and the wheels that support them, have gone through significant changes as a result of technical innovations in design, technology and materials. No single factor affects the handling and safety of a car’s ride more than the tire and the wheel it is mounted on and how the two work together as a unit. One nagging question that has been the subject of a lot of anecdotal evidence, speculation, and even more widespread rumor is whether rims designed for Bias ply tires can handle the stresses placed on them by Radial ply tires. And the answer is - it depends. It depends on how the rim was originally designed and built as well as whether the rim has few enough cycles on it, and how it has been driven. But most importantly it depends upon the construction of the tire and how it transmits the vehicle's load to where the rubber meets the road. In this paper, we want to educate you on the facts - not the wives tales or just plain bad information - about how Bias and Radial tires differ in working with the rim to provide a safe ride. Why is there a possible rim concern between Radial and Bias Tires? The fitting of radial tires, to wheels and rims originally designed for bias tires, is an application that may result in rim durability issues. Even same-sized bias and radial tires stress a rim differently, despite their nearly identical dimensions. -
Adaption and Evaluation of Transversal Leaf Spring Suspension Design for a Lightweight Vehicle Using Adams /C Ar
ADAPTION AND EVALUATION OF TRANSVERSAL LEAF SPRING SUSPENSION DESIGN FOR A LIGHTWEIGHT VEHICLE USING ADAMS /C AR FLORIAN CHRIST Master Thesis in Vehicle Engineering Vehicle Dynamics Aeronautical and Vehicle Engineering Royal Institute of Technology TRITA-AVE 2015:09 ISSN 1651-7660 Adaption and Evaluation of Transversal Leaf Spring Suspension Design for a Lightweight Vehicle using Adams/Car FLORIAN CHRIST © Florian Christ, 2015. Vehicle Dynamics Department of Aeronautical and Vehicle Engineering Kungliga Tekniska Högskolan SE-100 44 Stockholm Sweden ii Abstract This investigation deals with the suspension of a lightweight medium-class vehicle for four passengers with a curb weight of 1000 kg. The suspension layout consists of a transversal leaf spring and is supported by an active air spring which is included in the damper. The lower control arms are replaced by the leaf spring ends. Active ride height control is introduced to compensate for different vehicle load states. Active steering is applied using electric linear actuators with steer-by wire design. Besides intense use of light material the inquiry should investigate whether elimination of suspension parts or a lighter component is concordant with the stability demands of the vehicle. The investigation is based on simulations obtained with MSC Software ADAMS/Car and Matlab. The suspension is modeled in Adams/Car and has to proof it's compliance in normal driving conditions and under extreme forces. Evaluation criteria are suspension kinematics and compliance such as camber, caster and toe change during wheel travel in different load states. Also the leaf spring deflection, anti-dive and anti-squat measures and brake force distribution are investigated. -

As part of its mission to reduce fatalities and injuries, since model year 2001 NHTSA has included rollover information as part of its NCAP ratings. One of the primary means of assessing rollover risk is the static stability factor (SSF), a measurement of a vehicle’s resistance to rollover. The higher the SSF, the lower the rollover risk. -

ABSTRACT. Automobile have various parts which are important for good running of the vehicle. The most important safety components from a structural point of view are the road wheels. They are required to be lighter and more fascinating to the buyer all the time. This implies that it's important to perform a lot of accurate strength assessment on wheel styles. The wheel rim plays a major role in vehicle dynamics. This paper deals with the design and model of different wheel rims based on weight optimization and also structural analysis has been carried out. It has been compared with standard values by varying two different materials. In addition, from the obtained outputs of simulations and the weight optimization, we suggested Aluminium alloys as most suitable material for SUV. Model is created by using SOLIDWORKS software 2015 and structural analysis & weight optimization is done by using ANSYS WORKBENCH 16.0. 1 INTRODUCTION by considered two different materials namely Aluminum and forged steel and their relative performances have A sport or suburban utility vehicle (SUV) is similar to a been observed respectively. -

Modelling Commercial Vehicle Handling and Rolling Stability
357 CORE Metadata, citation and similar papers at core.ac.uk Provided by Bradford Scholars Modelling commercial vehicle handling and rolling stability K HussainÃ, W Stein, and A J Day School of Engineering, Design, and Technology, University of Bradford, Bradford, UK The manuscript was received on 3 September 2004 and was accepted after revision for publication on 28 April 2005. DOI: 10.1243/146441905X48707 Abstract: This paper presents a multi-degrees-of-freedom non-linear multibody dynamic model of a three-axle heavy commercial vehicle tractor unit, comprising a subchassis, front and rear leaf spring suspensions, steering system, and ten wheels/tyres, with a semi-trailer comprising two axles and eight wheels/tyres. The investigation is mainly concerned with the rollover stability of the articulated vehicle. The models incorporate all sources of compliance, stiffness, and damping, all with non-linear characteristics, and are constructed and simulated using automatic dynamic analysis of mechanical systems formulation. A constant radius turn test and a single lane change test (according to the ISO Standard) are simulated. The constant radius turn test shows the understeer behaviour of the vehicle, and the single lane change manoeuvre was conducted to show the transient behaviour of the vehicle. Non-stable roll and yaw behaviour of the vehicle is predicted at test speeds .90 km/h. Rollover stability of the vehicle is also investigated using a constant radius turn test with increasing speed. The articulated laden vehicle model predicted increased understeer behaviour, due to higher load acting on the wheels of the middle and rear axles of the tractor and the influence of the semi-trailer, as shown by the reduced yaw rate and the steering angle variation during the con- stant radius turn. -
