Abstract

The invention provides a ground trailer wheel for a skid helicopter, includes a hydraulic mechanism, a transmission mechanism and a suspension mechanism, The transmission mechanism (20) comprises a gear housing (21), a gear shaft (22) and a toothed rod (23), the gear shaft (22) is meshed with the toothed rod (23), the gear housing (21) is arranged outside the gear shaft (22) and the toothed rod (23), the hydraulic mechanism (10) can rotate the gear shaft (22) by driving the toothed rod (23), and the lower end of the gear housing (21) is detachably connected with the suspension mechanism (30).The wheel suspension mechanism for a ground trailer wheel of a skid helicopter comprises a plurality of suspension frames, and by replacing different suspension frames, a ground trailer wheel for theskid helicopter can be applied to different skid helicopters.

Description

[0001] This case is based on the divisional application of the parent case with the application number: 201611108283.7, the application date: December 6, 2016, and the name "ground tractor wheels for skid helicopters". technical field [0002] The invention relates to the field of helicopter ground support equipment, in particular to a ground tractor wheel for skid-type helicopters. Background technique [0003] With the continuous expansion of my country's skid helicopter market, the number has increased rapidly, and the guarantees for helicopters have been continuously strengthened. The tractor wheels that must be used by skid helicopters are even more indispensable. At present, most of the landing gears of light helicopters on the domestic and foreign markets adopt skid type landing gears, and domestic light helicopters have hoisting devices for tractor wheels of models such as Gazelle, Bell, Squirrel, Zhi-11, and EC120. Divided into four types: [0004] One is mainly ba...
