Detailed Description
The present invention will be described with reference to specific examples.
Fig. 1 to 5 are schematic structural views of the automatic vehicle body leveler according to the present invention.
The invention relates to an automatic leveler for vehicle body, comprising: the vehicle body bottom plate 10 is of a rectangular structure, a signal box 20 is arranged in the middle of the upper end face of the vehicle body bottom plate 10, an inclination angle acquisition ring 30 is vertically arranged on the signal box 20, and a liquid level sensor 31 is arranged on the outer side wall of the inclination angle acquisition ring 30, wherein the inclination angle acquisition ring 30 is of an annular pipeline structure, and a liquid medium is filled in the annular pipeline structure; the four right angles of the underbody 10 are respectively provided with a lifter 40 penetrating through the underbody 10, and the signal box 20 is connected with the lifter 40 through a data line 50; the bottom end of the lifter 40 is provided with a sliding barrel 60 in a hinged connection mode, one corresponding end of each of the two sliding barrels 60 positioned on the same side is provided with a male-female hinged part 70 used in a matched mode, a horizontal adjusting rod 80 penetrates between the two male-female hinged parts 70, the free end of each sliding barrel 60 is provided with a universal joint 61, the inner side of each wheel 90 is provided with a driving bearing 91, and the driving bearing 91 is rotatably connected with the universal joint 61; a pull rod 100 is arranged between the two wheels 90 positioned on the same side, a pull rod driven disc 92 is arranged on the driving bearing 91, the free end of the pull rod 100 is hinged with the pull rod driven disc 92, and an inner camber angle controller 200 matched with the pull rod 100 is arranged in the middle of the pull rod 100. In this scheme, ring 30 is gathered to angle of inclination when taking place the slope inside medium liquid can not receive the slope influence in the ring channel, and at this moment, the liquid level height can be listened to the level sensor 31 of pipeline outer wall to the system carries out attitude control. As shown in fig. 1: the signal is collected by the inclination angle collecting ring 30, and the signal is processed by the signal box 20 to send a command to the lifter 40 and the inner and outer inclination angle adjuster 200, the lifter 40 adjusts the level of the vehicle body to return the vehicle body to the right, and the inner and outer inclination angle adjuster 200 adjusts the wheels 90 to adapt to the slope.
