Description

Hub motor capable of mounting brake pad Technical Field The utility model belongs to the technical field of electric scooter, and particularly relates to a hub motor capable of being provided with a brake pad. Background The electric scooter is popular with young people from entering the field of view of the masses, and is converted into a walking tool along with the expansion of the audience group of the electric scooter. The electric scooter is used as a scooter, wherein the electric scooter not only can overcome the problem of physical limitation in the long-distance running process, but also can meet the requirements of people in speed. The control mode of the electric scooter is the same as that of a traditional electric bicycle, and the electric scooter is easy to learn by a driver, is provided with a detachable and foldable saddle, has a simple structure, small wheels, is light and convenient compared with the traditional electric bicycle, can save a large amount of social resources, and in recent years, the electric scooter with the lithium battery is rapidly developed, and has new requirements and situations. The braking mode of electric scooter is divided into hub brake and disc brake, wherein the disc brake is installed the outside of tire with the brake block, generally need fix it on the brake disc, although have the convenient benefit of checking and changing of dismantlement like this, it still has the problem that needs to occupy electric scooter holistic spatial position. For this reason, it is required to provide an in-wheel motor in which a brake pad can be conveniently mounted. Disclosure of utility model The utility model mainly aims to provide a hub motor capable of being provided with a brake pad, aiming at the defects of the prior art. In order to achieve the above purpose, the present utility model provides the following technical solutions: The utility model provides a wheel hub motor of mountable brake block, includes tire, wheel hub and motor, the wheel hub sets up the tire is inboard, the motor sets up the wheel hub is inboard, the motor includes the motor organism, sets up motor organism inside motor shaft and symmetry set up the motor casing of motor organism both sides, the both ends of motor shaft are symmetrical respectively cup joints wheel hub casing and the motor shaft with wheel hub casing fixed connection, wheel hub casing with the motor casing rotates to be connected, the outer lane of motor shaft is fixed to cup joint and is installed the bearing, the surface circumference array of bearing distributes and has the arch, every install on the arch with protruding spacing collar that sets up perpendicularly, spacing collar with be provided with the interval that can install the brake block that is used for braking electric scooter between the bearing surface.
