Embodiment Construction

[0020] Depend on figure 1 with figure 2 It can be seen that the present invention includes a base 1 , a push-pull rod 2 , a sector gear 3 , a control arm 4 , a central bolt 5 and a hydraulic cylinder 6 .

[0021] Depend on figure 1 with figure 2 It is also known that in order to realize the convenient assembly of the present invention and the vehicle frame (hull), a plurality of installation holes 1a are arranged in an orderly manner on the base 1, and the base 1 can be fixed in an orderly manner through the fastening bolts and the installation holes 1a. Both sides of the bottom of the frame (hull).

[0022] Depend on figure 1 with figure 2 It is also known that in order not to affect the normal operation of the wheels and the passability of the vehicle, the control arm 4 in the present invention is specially designed as a "rotary type". The control arm 4 takes the center hole 3a on the sector gear 3 as the center and can Rotate 90 degrees.

Abstract

The invention discloses a rotary control arm device. The rotary control arm device comprises a base, a push-pull rod, a sector gear, a control arm, a central bolt and a hydraulic oil cylinder, whereina rack at the lower end of the push-pull rod is orderly meshed with the sector gear, the central bolt is orderly and fixedly installed on the base, the sector gear sleeves the central bolt, and the control arm 4 is fixedly mounted on the sector gear 3. The device is scientific in design, compact in structure, reliable in performance, convenient to assemble and disassemble, low in cost and capableof being conveniently assembled with multiple kinds of amphibious vehicles and ships; moreover, the water resistance and impact resistance of the device are significantly improved, and the stabilityand safety reliability of the vehicles during floating on a water surface are improved.

Description

technical field [0001] The present invention relates to a general hydraulic mechanical device, in particular to a rotary control arm device which can be installed on both sides of the bottom of a vehicle. Background technique [0002] When the amphibious vehicle enters the state of floating on the water surface, its assembled folding pontoon or folding water ski will rely on two (or three) "rotating" wheels installed on the longitudinal position of the "pontoon" or "water ski". arm" to control it. Although this control method is simple in structure, under the impact of strong water resistance, there are still many uncertainties in the stability, safety, reliability and service life of the "pontoon" or "water ski". Contents of the invention [0003] The purpose of the present invention is to provide a "rotary control arm device" that is scientific in design, compact in structure, reliable in performance, convenient in loading and unloading, low in cost, and can be matched ...
