Abstract

The invention discloses a four-axle automobile chassis, which is provided with four axles, a front fixing support leg and a back fixing support leg, wherein the first axle is arranged at the front side of the front fixing support leg, the second axle, and the third axle and the fourth axle are arranged between the front fixing support leg and the back fixing support leg, wherein the first axle and the fourth axle are steering axles, and the second axle and the third axle are driving axles. Preferably, the first axle adopts a mechanical steering device and a steering assistor for driving the steering, and the fourth axle adopts a follow-up assistor for driving the steering. The four-axle automobile chassis provided by the invention can effectively balance the work load of each axle, so the carrying capability of the whole machine is improved, and simultaneously, the transition operation efficiency is further improved. On the basis, the invention also provides a four-axle automobile crane adopting the chassis.

Description

technical field

[0001] The invention relates to a wheeled engineering machine, in particular to a four-axle car chassis and a car crane with the chassis. Background technique

[0002] The four-axle car chassis has good passing performance and transition performance, and has been widely used in various types of construction machinery. For example, cranes, elevating fire trucks, etc. See figure 1 with figure 2 ,in, figure 1 shows the front view of the overall structure of the existing four-axle truck crane, figure 2 show figure 1 The top view of the chassis steering and drive shaft arrangement of the four-axle crane shown in .

[0003] Such as figure 1 with figure 2 As shown, the lifting operation part is connected with the chassis of the car through the turntable under the control room. The chassis of the truck crane is supported by four axles, of which the first and second axles are located at the front end of the vehicle, and the third and fourth axles are locate...
