Description
Technical Field
The invention relates to the technical field of balance cars, in particular to a single-shaft-support track wheel without transmission gaps.
Background
The balance car is an electric car capable of realizing self-balancing, and detects the change of the gravity center of a human body and the car body through a gyroscope and an acceleration sensor which are arranged in the car body, so that the direction and the speed of the car body are controlled, and the balance car has high flexibility. However, when the balance car passes through grass or other uneven roads, the car body is easily shaken and shaken, which brings bad riding feeling to users.
When the current self-balancing vehicle passes through a complex road surface, the vehicle usually runs unstably and is easy to turn over, and when the track passes through an undulating road surface, the undulating ground continuously abrades the track in the process of frequent front-back transmission, and the track driving plate can slip after the track is loosened.
Disclosure of Invention
