Abstract

The invention provides a hub motor with external spline shaft. Based on a traditional motor with three asynchronous machines and through the design change of shape and structure, the invention is allowed to be a hub motor with reliable performance, simple structure and strong practicality. Two sides of a motor shell are provided with motor pedestals perpendicular to motor shafts so as to continent for connecting with a suspension of an electric vehicle; the external end of the motor shafts are provided with the external spline and a wheel connector; a wheel and a brake drum or a brake disk are arranged on the wheel connector on the external end of the motor shaft by a wheel bolt. A brake floor and a brake clamp support are arranged on an external side end cover of the hub motor. The internal end of the motor shaft is provided with a gap-adjusting nun used for adjusting the gaps of the bearing, namely, used for adjusting the gaps of the wheels in real usage. The invention is applicable to the manufacture of small-sized electric vehicle.

Description

Technical field [0001] The invention relates to a vehicle motor, in particular to an external spline shaft hub motor. Background technique [0002] The use of hub motors to drive electric vehicles can save engines and complex transmission mechanisms, reduce power transmission losses, and improve energy efficiency ratios. It is the most advanced driving method for electric vehicles. There are many types of in-wheel motors, either too simple and poor in performance, or too complex and poor in applicability. The technology is not mature enough, and most of them stay in the research and development stage, and few of them enter the practical stage and go to the market. This is also one of the reasons why electric vehicles are mostly driven by main power motors and transmission systems. The advanced nature of hub motor drives determines that it is an inevitable need for the development of electric vehicles, so a hub motor with simple structure, practicality and reliable performan...
