IT would be hard to find an industry, coming under the general heading of engineering, in which a more diverse variety of specialized products is employed than in that devoted to commercial-motor manufacturing. To review comprehensively every single part and component in a modern chassis is utterly impossible in an article of this description.
We have, therefore, prepared a list of the concerns engaged on the class of work under discussion, grouping their names under headings explanatory of their products and, in certain • cases, adding a further description of the individual article or substance produced.
There are certain items, however, that are specially noteworthy as indicative of progress or modern tendencies; these we briefly describe.
The first heading calls for comment in view of if o'fact that the frames of commercial vehicles need to be capable of; standing up to heavy overloads. Most manufacturers obtain their steel sections, shaped cross-members, longitinlinals or the assembled frames from engineering concerns 'spealizing in forging antl presswork: 'Modern metallurgy and, to a small extent, the employment of welding are responsible for the reply to the new demand for frames lighter than„ever, but no less sturdy than before4 other presswork is obtained from sinlar sources.
Castings for vehicles are mainly in iron, steel, aluminium,. Elektron, 3.}82 bronze, brass and white metal. The concerns, named below, largely specialize on each class; we have, accordingly, named the products in every case. Aluminium for cylinder heads is more often used than in the past. Elektron grows more popular, and hard irons for cylinder blocks are in demand. Piston alloys have progressed. It hasbeen said on several occasions that little development has been made in springs. This statement is open to dispute. Jonas Woodhead products, for example, represent scientific spring making; silico-manganese alloys provide a material greatly superior to earlier , spring steels; •pyrometers enable heat treatment to be given with precise knowledge, and testing appliances are now highly efficient and exacting .
The Cary open-plate-type of progressive spring deserves mention, and it is of interest to record the popularity of helper springs, with which the names of Edge, Evans and Sales are associated. Solid-forged eyes and the Woodhead trunnionend are also noteworthy, whilst the Gross air spring is a refinement that deserves wider adoption.
In this connection, a new shock absorber, in the functioning of which air plays a part, is being developed by Turner's Motor Manufacturing Co., Ltd. We hope to describe this more fully in a later issue. A development in shock absorbers is the use of master controls . operable from the driver's seat, such as the Andre Hydro Telecontrol system.
Many improvements have been made in brake systems, but perhaps the wide adoption of the Lockheed system and the combination therewith of servo systems is the form of progress that most merits comment. Successful efforts to eliminate time lag in vacuum servo systems have been made. The matter of brake developments is dealt with fully elsewhere.
Achievements of brake-facing makers include the stabilizing of the coefficient of friction, with variations of temperature, and the use of material which does not score the drums. It is of interest to mention that certain makers list special low-friction facings for self-energizing brakes.
'Bearings of the needle-roller type, for parts subject to oscillating motion, have recently come into general usage, notably for universal joints and bogie rocking beams. A reference to this is made . in an article on major corn ponents appearing elsewhere in this issue. Another development is the permanent scaling of races to retain grease and to prevent the entry of grit, dirt or swarf, thus increasing their durability.
Diamond boring of white-metal bearings and the elimination of the need for hand scraping is a development in this sphere.
Efforts on the part of makers of front-axle assemblies and steering gears tend towards lighter steering without loss of stability. Servo steering has. not as yet materialized in this country. Steering wheels with spring arms gain favour.
Grouping of grease nipples for chassis lubrication may be superseded by central lubricators from which all points are fed. The principle recalls the very early vehicles on the dash. boards of which was an array of dripfeed oilers.
In the Welson system a master ram is actuated by variations in engine oil pressure. The Ripaults central lubricator employs a tank, from which oil can flow only during motion of the vehicle (cessation of vibration stops the supply), and calibrated fittings, that permit only the right quantity to reach each point.
The Tecalemit device similarly depends upon the inertia of a moving part to dispel the oil from the reservoir only during motion.
