Description

Running gear and scooter that can brake

[ technical field ] A method for producing a semiconductor device

The utility model relates to a running gear that can brake, the utility model discloses still relate to an use this running gear's that can brake scooter.

[ background of the invention ]

In the prior art, a common wheel set is formed by connecting wheels with a shaft through a rolling bearing, steering is realized by controlling the swinging of the shaft, the distance between the two wheels is kept unchanged, and the structure is difficult to meet a load device with special requirements during walking. For the steering requirement, generally adopt the universal wheel, conventional universal wheel adopts rotating-structure and rolling structure to superpose and forms, and rotating-structure sets up on rolling structure, adopts this design structure, has a more obvious defect just to make the load structure's of connecting this wheel subassembly focus higher, so the phenomenon of toppling appears easily in the safety problem, is unfavorable for safety, and also is not convenient for control its direction that keeps stable in the rolling in-process and goes.

The scooter with the structure is driven to slide while stepping on the ground by manpower, and the scooter is pushed to move forwards by the forward reaction of the ground, so that the scooter is not labor-saving to slide and has short sliding distance. In addition, the existing scooter brake generally has three modes of foot brake, board tail brake and transverse brake.

Among them, the foot brake is very common in the skateboard, namely, during the sliding, the front foot steps on the board, meanwhile, the center of gravity of the body is placed on the front foot, and the rear foot is rubbed on the ground, so that the purpose of speed reduction and braking is achieved, and the mode is relatively expensive.

The plate tail brake is that in the process of sliding, a rear foot is used for stepping on the plate tail, and the plate tail rubs the ground to achieve the purpose of speed reduction and braking. The brake mode has certain requirements on the balance of the sliding hand, a beginner can not control the sliding hand well, and the plate tail brake is cool in appearance but costs the plate tail.

The transverse brake is that the body drives the rear foot push plate, the plate is transversely crossed, and the side surface of the wheel rubs the ground to achieve the purpose of speed reduction and braking. The requirement of the transverse brake on the sliding hand plate is high, so that the transverse brake can act on the sliding hand plate, and the transverse brake is difficult to master.

The three braking modes have large danger coefficients and are not safe enough.

To the deficiency of the prior art, the utility model discloses relevant and research and development has been carried out to this point to new technical scheme has been proposed.
