技术领域technical field
本实用新型涉及无轨陆用车辆,具体涉及无轨陆用车辆的车轮,特别是既可在平地上平地行走,又可翻动登攀阶梯的登楼轮。The utility model relates to a trackless land vehicle, in particular to a wheel of the trackless land vehicle, in particular to a building climbing wheel which can not only walk on the flat ground, but also turn over the stairs.
背景技术Background technique
传统的无轨陆用车辆的车轮均是由单个车轮通过轴与车体联接,车轮连续与地面接触滚动实现车辆运行。设有这种车轮的车辆,只能在平坦的路面上行驶,一旦碰到较陡的凸起(如楼梯等),车辆运行就发生困难。The wheels of traditional trackless land vehicles are all connected to the vehicle body by a single wheel through an axle, and the wheels continuously contact and roll with the ground to realize the operation of the vehicle. Vehicles with such wheels can only run on flat roads. Once they run into steeper bumps (such as stairs, etc.), the vehicle will run into difficulties.
为了克服这一问题,人们进行了大量的研究工作,中国专利CN2051919U公开了“一种攀楼、平地多用车”,其通过在车身的横轴两端装上行星轮来实现,这种行星轮实际上是由4个小轮与轮架组成的一个从动轮系。这种结构的轮系虽可在人力推拉车上使用,但其运行时仅限于人力推拉车上应用,特别费劲,且不安全,因而很难推广应用。In order to overcome this problem, people have carried out a lot of research work. Chinese patent CN2051919U discloses "a multi-purpose vehicle for climbing buildings and leveling ground". In fact, it is a driven train consisting of 4 small wheels and a wheel frame. Though the wheel train of this structure can be used on the manpower push-pull cart, its running time is only limited to the application on the manpower push-pull cart, is particularly laborious, and unsafe, thereby is difficult to popularize and apply.
中国专利CN2209099Y公开的“登攀轮”,它为一种星轮行星轮可转换式登楼轮,该登攀轮包括具有3-8个放射状转臂的轮架、车轮,车轮设置在轮架各转臂的端部;轮架通过一中心轴与车身连接;在中心轴上设有中心齿轮,各车轮的轴上分别设有同轴从动齿轮(行星齿轮),中心齿轮与各行星齿轮之间分别设有惰轮,中心齿轮与惰轮相互啮合,惰轮与行星齿轮相互啮合。该登攀轮在中心齿轮的一端及轮架上各设有爪型离合器,中心齿轮在中心轴上能自由转动,中心轴上有花键的部分设有可轴向滑动的双面爪型离合器,在弹簧的压力下,与中心齿轮的离合器部分啮合,接受中心轴传递来的驱动力矩,实现平地上的运动。当车轮受到阶梯的阻挡时,由于车轮不能动,导致中心齿轮不能转动,这时双向爪型离合器在传动力矩的作用下,被迫与中心齿轮脱离,从而与固定在轮架上的爪型离合器啮合,使轮架向阶梯上翻转。The "climbing wheel" disclosed in Chinese patent CN2209099Y is a convertible star-wheel planetary wheel. The climbing wheel includes a wheel frame and wheels with 3-8 radial arms. The wheels are arranged on each arm of the wheel frame The end of the wheel; the wheel frame is connected with the body through a central shaft; a central gear is provided on the central shaft, and coaxial driven gears (planetary gears) are respectively provided on the shafts of each wheel, and the central gear and each planetary gear are respectively An idler gear is provided, the sun gear and the idler gear are meshed with each other, and the idler wheel and the planetary gear are meshed with each other. The climbing wheel is equipped with claw clutches on one end of the central gear and on the wheel frame. The central gear can rotate freely on the central shaft, and the splined part of the central shaft is provided with a double-sided claw clutch that can slide axially. Under the pressure of the spring, it meshes with the clutch part of the central gear, accepts the driving torque transmitted by the central shaft, and realizes the movement on the flat ground. When the wheel is blocked by the ladder, the center gear cannot rotate because the wheel cannot move. At this time, the two-way jaw clutch is forced to disengage from the sun gear under the action of the transmission torque, so as to be connected with the dog clutch fixed on the wheel frame. Engage to flip the wheel frame up the steps.
该登攀轮能广泛应用于人力推拉车,轮椅、自行车、摩托车、小汽车等多种类型车辆,使车辆既能在平地运行自如,又能登攀阶梯。但该登攀轮存在以下缺陷:1.中心齿轮、惰轮、行星齿轮所组成的行星齿轮系为开式齿轮,易受外界干扰,影响登攀轮工作的稳定性;2.离合器为自动转换方式,结构复杂,可靠性差;3.离合器结构复杂且在转臂内部,整体结构不紧凑。The climbing wheel can be widely used in various types of vehicles such as human push-pull vehicles, wheelchairs, bicycles, motorcycles, cars, etc., so that the vehicles can not only run freely on flat ground, but also climb stairs. But this climbing wheel has the following defects: 1. The planetary gear train composed of central gear, idler gear and planetary gear is an open gear, which is easily affected by external interference and affects the stability of the climbing wheel; 2. The clutch is an automatic conversion mode, The structure is complex and the reliability is poor; 3. The clutch structure is complex and is inside the rotating arm, and the overall structure is not compact.
