This SAE Recommended Practice outlines the qualification testing and performance related criteria of elastomeric boot seals used in constant velocity joint applications. These applications are referred to as front- wheel-drive halfshafts or axles, but can also be utilized in rear-wheel-drive halfshaft applications. For additional information regarding CV joint systems and their applications refer to SAE AE-7 "Universal Joint and Driveshaft Design Manual." The grease type and grease quantities, clamps and clamping mechanisms of an assembly are critical and considered to be the same as OEM, service, or aftermarket designation. Although joint lubricating grease and clamping mechanism are not addressed in this document, they are critical to a total system performance. The purpose of this document is to establish a uniform practice for those in the surface vehicle industry that specify and/or manufacture CV joint boot seals (boots) for OEM or aftermarket use with respect to qualification testing for physical and mechanical properties.

The new Supplying PSA Peugeot Citroën analyses the ways in which PSA Peugeot Citroën is moving forward in terms of models and technology, including what issues are affecting the OEM in terms of supply and manufacturing. The report is based on interviews with key purchasing executives. Although PSA is being negatively affected by the economic situation in Europe, the carmaker is set to kick off an aggressive period of growth in China, still the largest and strongest new car market in the world. This is backed by joint-ventures with local partners Dongfeng and Chang An, both in terms of production and also in R&D. Advanced build and powertrain solutions will serve as the basis of a series of new vehicles, the development of which will be supported by the EUR3 billion of liquidity generated by direct company investment and new share offerings. How this plays out over the remainder of the decade and into the 2020s will be critical to the future of PSA. Should these strategies deliver success, then the OEM is virtually guaranteed a continued place at the top table of global car manufacturers.

The increasingly stringent emissions regulations faced by vehicle manufacturers have been driving the growth of more fuel-efficient conventionally powered vehicles. The ability of stop-start systems to improve vehicle carbon emissions by between 5% and 15% at very low additional cost has seen a dramatic increase in the proportion of vehicles being fitted with such systems. And this growth in demand for stop-start systems is set to increase substantially, especially in Europe, North America, China and Japan. The exclusive new report from ABOUT Automotive reviews the key market drivers for stop-start engine technology for the ‘micro hybrid’ segment and conventional internal combustion engine (ICE) vehicle applications. It sets out the market drivers and forecasts for the global stop-start systems market through to 2020 and reviews the technical advances made in stop-start technology, including the competing technologies, and the latest developments. It also profiles a number of major suppliers of stop-start systems.

Abstract Tubular stabilizer bar for commercial vehicle is developed using advanced high strength steel material. Tubular section is proposed to replace the existing solid section. The tubular design is validated by component simulation using ANSYS Software. The tubes are then manufactured of the required size. The bend tool is designed to suit the size of the profile stabilizer bar and the prototypes are made using the tube bending machine. The strength of the tubular stabilizer is increased by using robotic induction hardening system. The tubular stabilizer bar is tested for fatigue load using Instron actuators. Higher weight reduction is achieved by replacing the existing solid stabilizer bar with the tubular stabilizer bar.

Today’s designers seek to integrate sensor technology, electronic and mechatronic systems in progressively introducing Electric Power Steering (EPS) systems. However, from a customer perspective on the one hand steering is one of the most visible or tangible aspects of vehicle quality in driving when quality is compromised (through NVH issues), while on the other hand, when executed well, a steering system is all but transparent to the driver. To a number of commentators and OEMs ‘steering feel’ has become termed as contributing to the essential ‘DNA” of the vehicle, and it is therefore an essential aspect of competitive advantage or position. This report examines steering feel and the increasing effect of vehicle electrification, and looks at steering and chassis performance. It also considers the key drivers including fuel efficiency and CO2 emissions, steering design, materials considerations and the packaging dilemma. Furthermore the report looks at the latest steering system trends, in particular electrically power assisted steering (EPAS), electro-hydraulic power steering (EHPS), electric power steering (EPS), active front steering (AFS), four-wheel steering, steer-by-wire, automated parking and NVH reduction.

This new report looks the marketplace for global medium and heavy commercial vehicle OEMs, their globalization process and the impact of new technologies on production. The report also includes an appendix of 21 major truck supplier profiles. These profiles provide relevant data on corporate strategy, investments, product offerings and contact information. Commercial-vehicle manufacturers around the world face a complex set of challenges that together add up to mounting pressure on their profit margins. Companies are grappling with the impact of the double-dip recession in Europe, with intensifying competition from emerging-market players, with the increased commoditization of their product, and with ever-tightening environmental regulations. In volume terms, capacity management remains the single most challenging issue for many OEMs. Having reached record levels in 2011, global demand for regional and heavy commercial trucks softened in 2012 before experiencing a small rebound in 2013.

Abstract Fast to market trends among automotive OEM's in introducing new vehicles has resulted in compressed product development time. Now it is fairly common to see CAE driven processes playing upfront role in the concept and advance stage of vehicle development thus adding pace to the Virtual Vehicle Development (VVD). In the recent decade we have also noticed acceptance of optimization driven by CAE models upfront in the virtual vehicle development process. Now a days it is not uncommon to use CAE models for optimization upfront at the advanced vehicle development stage with CRASH and NVH performance objectives. Yet another noticeable transformation happening in accelerating VVD is ability to use morphing techniques on CAE models to bring about design changes or enablers independent of CAD. Ability of morphing tools to make design changes in CAE model parametric adds significant value to the optimization process. Parametric CAE models tied to DoE or direct optimization based techniques help identify the optimal point for interdisciplinary objectives way ahead in the VVD.

Abstract The durability evaluation of overhanging components of a vehicle (Ex: horn, radiator) is a challenge to durability engineers as resonance plays an important role in determining their fatigue life. As resonance cannot be avoided always, it is desirable to develop methods to evaluate life of the component in the presence of resonance. Though the existing vibration test standards suggest test profiles to evaluate resonance failures, there are cases in which, these methods do not yield the proving ground results. This may lead to unnecessary overdesign or unrealistic failures. In such cases it is suggested to generate a sweep endurance test procedure customized to the proving ground or actual roads. This paper studies a methodology for generating a sweep endurance test procedure for evaluation of resonating components. Responses like stress and accelerations were measured in test components in proving ground. Contribution of each frequency band towards overall damage is determined.
