Embodiment Construction
[0034] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0035] In the present invention, unless stated to the contrary, the used orientation words such as "up and down" generally refer to up and down as shown with reference to the accompanying drawings.
[0036] Such as Figure 4 As shown, one aspect of the present invention provides a driving axle balancing device, the driving axle balancing device 1 is connected between the vehicle frame 2 and the swing frame 3, wherein the driving axle balancing device 1 includes elastic members 12 connected to each other and an elastic force adjustment mechanism 11, the elastic member 12 is used to apply tension between the vehicle frame 2 and the swing frame 3, and the elastic ...

The invention discloses a drive axle balancing device. The drive axle balancing device (1) is connected between a frame (2) and a swing frame (3), and comprises an elastic element (12) and an elastic force adjustment mechanism (11) which are connected with each other, wherein the elastic element (12) is used for applying a pulling force between the frame (2) and the swing frame (3), and the elastic force adjustment mechanism (11) is used for adjusting the pulling force applied by the elastic element (12). The invention further discloses engineering machine with the drive axle balancing device. According to the invention, the drive axle balancing device is arranged between the frame and the swing frame, the problem of drive axle deflection caused by the fact an operator tries to correct the errors due to misoperation is avoided, and in addition, as the drive axle balancing device disclosed by the invention is provided with the elastic force adjustment mechanism, the pulling force applied between the frame and the swing frame can be adjusted.
Description
technical field [0001] The invention relates to the field of construction machinery, in particular to a driving axle balancing device and a construction machine with the driving axle balancing device. Background technique [0002] Such as figure 1 As shown, the construction machinery with swing suspension locks the swing cylinder 4 through the electric control hydraulic lock after the parking brake, so that the driving axle 5 remains parallel to the ground. Because the center of gravity of the drive axle 5 does not coincide with the swing center of the swing frame 3 (ie the centroid of the drive axle), the drive axle 5 will deflect in a free state. Such as figure 2 As shown, in this case, when the operator forgets to lock the swing cylinder 4 before opening the legs, he will fully open the legs (not shown), and the drive axle 5 will deflect under the action of gravity at this time, when the swing When the angle is 7 degrees, the height difference between the tires on bot...
