Problems solved by technology

In the various existing hub designs, the steering system is placed outside the hub, and most of them are relatively complicated. In the process of use, a series of complicated mechanisms are required to realize the steering of the hub.
There are following deficiencies in these hub structures: 1, the traditional various hub steering systems are designed outside the hub, and the required space is relatively large, and in some special cases, especially for high-precision machines (such as detectors), the space It is very valuable to them; 2. The traditional steering system is relatively complicated, and the production process is very strict, the process is complicated, and the production cycle is long, so the cost is relatively expensive; 3. The traditional steering system is relatively complicated, so its The control stability will decrease accordingly

Abstract

The invention discloses a hub assembly with a built-in independent driving system and a built-in steering system. The hub assembly comprises a hub, a steering system and an independent driving system positioned inside the cover of the hub. The steering system comprises a supporting bridge, a pivot pin, a central axis, a steering reducer and a steering motor. The output shaft of the steering motor is connected with the pivot pin via the steering reducer. The steering reducer is fixedly connected with the supporting bridge. The central axis is fixedly connected with the pivot pin. The hub is fixedly connected with a connecting frame which is positioned on the central axis via a bearing. The independent driving system is fixedly positioned on the central axis. The invention has the advantages of simple structure, convenient control, low cost, high stability, especially being suitable for the hubs with the high demands for space utilization and lightweight structure and the built-in independent driving system and the built-in steering system with high reliability.

Description

technical field [0001] The invention mainly relates to the field of wheel hub design of a walking system, in particular to a wheel hub with built-in independent drive system and steering system. Background technique [0002] For the walking system, the hub is a very important part. In the existing designs of various hubs, the steering system is placed outside the hub, and most of them are relatively complicated. During use, a series of complicated mechanisms are required to realize the steering of the hub. There are following deficiencies in these hub structures: 1, the traditional various hub steering systems are designed outside the hub, and the required space is relatively large, and in some special cases, especially for high-precision machines (such as detectors), the space It is very valuable to them; 2. The traditional steering system is relatively complicated, and the production process is very strict, the process is complicated, and the production cycle is long, so ...
