Fig. 2 is the schematic diagram of a structure of the damping oil cylinder shown in installation diagram 1;
Detailed description of the invention
Fig. 1 shows trailing wheel T is arranged on to a kind of structure on a vehicle or engineering truck vehicle 10. Vehicle 10 has a vehicle frame 10a. Trailing wheel T is arranged on the two ends of axletree 11, and axletree 11 is positioned at the rear portion of vehicle 10. Axletree 11 by a central pin 11a rotatably support to vehicle frame 10a.
Vehicle frame 10a and axletree 11 are also interconnected by a shock absorber or hydraulic damping oil cylinder 12. Damping oil cylinder is Multidirectional hydraulic oil cylinder, the power of its attenuation on trailing wheel T.
Fig. 2 shows hydraulic damping oil cylinder 12 and comprises a cylinder barrel 12a, is arranged on a piston 12b and a piston rod 12c in this cylinder barrel 12a, and its one end is connected with this piston 12b. The other end of piston rod 12c is connected on axletree 11.
Piston 12b is at interior restriction the first oil pocket R1 of shock absorber 12 and the second oil pocket R2. First and second oil pocket R1, R2 are connected to a controller 13 through pair of channels P respectively. Controller 13 opens and closes passage P selectively, to control flowing and locking or release damping oil cylinder 12 therefrom of damping oil cylinder 12 interior hydraulic oil. That is: controller 13 lockings or release damping oil cylinder 12, to keep maneuvering performance and the ride performance of stability and raising vehicle 10. Damping oil cylinder 12 also can be used for adopting in the vehicle of polytype damping oil cylinder.
Circular cylinder barrel 12a has a top connection 20, is extended with the first through hole 20a in this top connection 20. Piston rod 12c also has a lower contact 21, is extended with the second through hole 21a in this lower contact 21. It is upper that bracket 22 is fixed on vehicle frame 10a, and with shock absorber for supporting 12, this bracket 22 has the wall of pair of parallel. The first support holes 22a extends through each wall or the supporting leg of bracket 22. The top connection 20 of cylinder barrel 12a is arranged between all walls of bracket 22. One bolt 23 inserts the first support holes 22a and the first through hole 20a and is fixed by a nut (not shown). Thus, cylinder barrel 12a is pivotally connected on vehicle frame 10a.
Described bracket 22 has the first support holes 22a, described bottom bracket 24 has the second support holes 24a, the top connection 20 of described shock absorber 12 has the first through hole 20a, the lower contact 21 of described shock absorber 12 has the second through hole 21a, the top connection 20 of described shock absorber 12 and lower contact 21 are connected with bracket 22 and bottom bracket 24 rotationally by a bearing pin 25 respectively, and wherein bearing pin 25 is to extend through at least one first, second support holes 22a, 24a and first, second through hole 20a, 21a accordingly around the rotating mode of its axis.
