Dongfeng-DANA Star Products Axle Low-floor
In order to meet the demand of low-floor axle of city bus and superior bus, DANA cooperated with Hungary RABA in 2001. On the basis of absorbing technology, DANA developed big-fall front axle, rear axle and trailer axle for low-floor bus. The axle has the advantages of low self weight, high torque, low noise, stable running, high carrying capacity, long fatigue life, multi-angles input, low heat effect, easy to adjust and good maintenance performance. By the end of 2007 all the of parts have been localized.
At present, the axle is widely used in city bus market, especially in low-floor bus. Its application reaches the same level as imported products of the same kind, and has been recognized by customers.
