Embodiment Construction
[0076] The brake of the invention can be applied to various vehicles using electric wheel drive technology, and the brake can cooperate with the motor regenerative braking in the electric drive vehicle to work. It is especially suitable for electric vehicles with large braking torque requirements, heavy loads and limited space for electric wheels. But the present invention is not limited to two-wheeled motor vehicles, golf carts or three- or four-wheeled vehicles for the elderly or disabled, medium and heavy-duty commercial vehicles used in construction sites or transportation industries, and tracked vehicles.
[0077] The left and right directions in the present invention are relative concepts, and are not limited to the left and right of a specific viewing orientation.
[0078] This application manual and the attached Figure 1-11 Take the electric wheel on the left side of the vehicle as an example to describe in detail. For the electric wheel on the right side of the vehi...

The invention provides an electric wheel integrally provided with a brake with a pinball pressurization structure. The electric wheel comprises the brake with the pinball pressurization structure. Thebrake is composed of a friction pair structure, a brake force providing device and the pinball pressurization structure. The brake is arranged between a wheel rim and a high-speed motor shaft body end cover flange, a fixing piece of the brake is fixedly connected with the motor end cover flange, a friction disc connecting piece is connected with a main supporting piece on the electric wheel through a spline and can drive the whole friction pairs to rotate along with the wheel. The brake is transferred through the pinball pressurization structure, the friction pairs are pressed and generate braking torque, and meanwhile the braking torque is enlarged. By means of the brake, the radial and axial space of the electric wheel is saved to a great degree, according to the electric wheel, the brake with the pinball pressurization structure is effectively connected with a wheel hub assembly, and efficient braking and large-torque braking are realized.
Description
technical field [0001] The invention belongs to the technical field of electric drive for electric vehicles, and in particular relates to an electric wheel integrated with a brake of a pin-ball pressurized structure and a vehicle with the same. [0002] technical background [0003] The electric wheel technology is also called the in-wheel motor technology, and the motor is a hub motor, which is characterized by integrating the vehicle's power device, drive device and brake device in the limited space of the wheel hub. This simplifies the mechanical transmission of electric vehicles. Compared with ordinary electric transmission technology, the vehicle no longer needs components such as differentials, half shafts, and universal joints. It has the advantages of short transmission chain, high transmission efficiency and flexible layout. At the same time, due to the obvious advantages of electric wheel technology in terms of power and control, it has attracted more attention from...
