Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As illustrated in fig. 1 and 2, the front wheel lean lockable mechanism that the utility model specific embodiment proposes comprises crane span structure 1, first inclination joint 2, second inclination joint 3, first steering knuckle 4, second steering knuckle 5, inclination pull bar 6, dump ram 7, support 10 and limiting stopper 11, and support 10 is connected with crane span structure 1; First inclination joint 2 and the second inclination joint 3 are hinged on the two ends of crane span structure 1 respectively by horizontal rotating shaft, first steering knuckle 4 and the second steering knuckle 5 are hinged on the first inclination joint 2, second inclination joint 3 by vertical rotating shaft respectively, and the two ends of inclination pull bar 6 are hinged with the first inclination joint 2, second inclination joint 3 respectively; One end and the crane span structure 1 of the first steering cylinder 9 are hinged, its other end and the first steering knuckle 4 hinged; One end and the crane span structure 1 of the second steering cylinder 8 are hinged, the other end and the second steering knuckle 5 hinged; One end of dump ram 7 is hinged on crane span structure 1, and the other end is hinged on the first inclination joint 2.On road grader, front-wheel is connected on the first steering knuckle 4 and the second steering knuckle 5 by wheel hub, when road grader turns to, the first steering cylinder 9 and the second steering cylinder 8 order about the first steering knuckle 4, second steering knuckle 5 respectively around vertical axis of rotation, and then change the direction of road grader front-wheel; During front wheel lean, dump ram 7 stretches out and orders about the first inclination joint 2 around horizontal rotating shaft rotation, and under inclination pull bar 6 acts on, the second inclination joint 3 also turns an angle around the horizontal rotating shaft of himself, and then drives front wheel lean.
In order to prevent front-wheel run-off the straight in transportation, the end face of inclination pull bar 6 is provided with the position-limited trough 12 of upward opening, as shown in Figure 2, limiting stopper 11 is horizontally disposed with, and its one end is fixing over the mount 10 by two bolts 13, the other end snaps in position-limited trough 12, and then by inclination pull bar 6 locking, correspondingly, the first inclination joint 2 and the second inclination joint 3 all cannot rotate around horizontal rotating shaft, therefore, front-wheel cannot tilt.
The conveniently setting of limiting stopper 11, be provided with three the first bolts hole 15 over the mount 10, as shown in Figure 4, three the first bolts hole 15 are at right angles arranged, as shown in Figure 3, limiting stopper 11 is provided with two the second bolts hole 14, bolt 13 is through fixing over the mount 10 by the first bolt hole 15 after the second bolt hole 14, when locking inclination pull bar 6, two bolts 13 coordinate with horizontal two the first bolts hole 15, when removing locking, two bolts 13 coordinate with two the first bolts hole 15 vertically arranged.
Certainly, in other embodiments, also other structure can be adopted to realize the conversion of limiting stopper 11 at lockup state and released state, such as by over the mount 10 hinged for one end of limiting stopper 11, when locking inclination pull bar 6, limiting stopper 11 turns to level attitude and snaps in position-limited trough 12, is then fixed in the middle part of limiting stopper 11 and support 10 by bolt 13, when removing locking, limiting stopper 11 is turned to vertical position and by bolt, the middle part of limiting stopper 11 and support 10 is fixed.
Obviously, compared with prior art, the operation of the front wheel lean lockable mechanism of said structure is more simple, convenient, and limiting stopper 11 can also be prevented to be lost when not carrying out spacing.
In addition, the utility model specific embodiment also proposes a kind of road grader, comprises frame and mobile devices, and frame supports on the ground by mobile devices, and mobile devices comprise the front wheel lean lockable mechanism of said structure, and support 10 is connected with frame.
Compared with prior art, by adopting above-mentioned front wheel lean lockable mechanism, this road grader can realize locking and the unblock of front wheel lean more easily, and effectively can also prevent the loss of related components.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
