| - 23 - It is meant to shew, however, that the air 'spring' is inherently suited to the absorption of small road inequalities while being still capable of keeping the axle off the buffers on bad roads. Another advantage of the air spring is that it can easily be adjusted for different loads by increasing or decreasing its air content. It is unnecessary to stress the disadvantages of air springs. There is bound to be a considerable amount of friction due to the cup leathers. Some provision must be made for checking rebound. The prevention of leakage is a very real problem. As at present produced, even though only used as an auxiliary device in conjunction with the normal leaf spring, the air container is bulky. If incorporated in a similar manner to that of the Lancia helical spring suspension, however, it should not necessarily be unsightly. The main question to be decided by the designer is - Do the advantages of the air spring compensate for the difficulties encountered in its design and cannot substantially the contd. | ||
