ENGINEERING VEHICLE AND CHASSIS THEREOF

摘要

A chassis of an engineering vehicle comprises at least two axles (13) and a girder (11) connected to all axles (13). The girder (11) comprises a first girder part (111) and a second girder part (112) connected to the first girder part (111), and a connecting opening between them is located between two axles (13). The chassis also comprises a telescopic device (12) operated along the direction of the length of the vehicle body. Two ends of the telescopic device (12) are separately connected to the first girder part (111) and the second girder part (112), which is slidably connected to the first girder part (111). The chassis has structure of adjusting the wheelbase between the axles (13), which solves the problem of axles (13) overload resulted from uneven load distribution, balances the load distribution of all axles (13), and achieves optimum transporting status of the vehicle. An engineering vehicle comprises the aforesaid chassis.
