Planetary dual purpose wheel for going upstairs/downstairs and walking

Abstract

The invention relates to a planetary dual purpose wheel for going upstairs / downstairs and walking. The dual purpose wheel is characterized in that a auxiliary wheel arm (4) on a planetary wheel frame(7) is arranged between each pair of adjacent two main wheel arms (5), an auxiliary planetary wheel (2) is moveably arranged on the end of the auxiliary wheel arm (4) of the planetary wheel frame (7)through an auxiliary wheel axis (3), the axes of a main planetary wheel (1) and the auxiliary planetary wheel (2) are on the periphery of one coaxial planetary wheel, the diameter of the shaft centerof the auxiliary planetary wheel (2) on the planetary wheel circle is less than the diameter of the shaft center of the main planetary wheel (1) on the star wheel, and a stop pinhole (9) matched withthe frame is arranged on the planetary wheel frame (7). The wheel of the invention arranges the auxiliary planetary wheel between each two adjacent main planetary wheels, and the auxiliary planetary wheel can ensure that the back main planetary wheel can move smoothly onto one upper step so as to have much buffer function and greatly reduce the vibration and bad feeling of a user caused by the uneven stairs. The wheel has simple structure and low production cost, and is easy to popularize and use.

Description

[0001] The invention relates to a vehicle, in particular to a wheel of the vehicle, in particular to a planetary dual-purpose wheel for walking on stairs and turning over stairs. Background technique: [0002] The wheels of traditional vehicles are all connected to the vehicle body through a single shaft, and the wheels continuously contact and roll with the ground to realize the operation of the vehicle. But this vehicle can only travel on a flat road surface, once it runs into a steeper bump (such as stairs, etc.), the operation of the vehicle will be difficult. [0003] In order to overcome this problem, people have carried out a lot of research and development work, as Chinese Patent No. 89200339.1 discloses a kind of vehicle for climbing buildings and flat ground; Although it can achieve the purpose of carrying goods and carrying people to go upstairs, and has the characteristics of easy use, its complex structure and high cost are not suitable for popularization.
