Problems solved by technology

However, because these parts belong to the high safety level parts of the vehicle, their manufacturing cost is relatively high
In addition, in order to cooperate with the above-mentioned main parts, the oil circuit and brake control components required for braking also need to be arranged on the chassis, resulting in high maintenance costs

Embodiment Construction

[0016] In order to make those skilled in the art better understand the technical solutions in the embodiments of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. The embodiments described above are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the embodiments of the present application should fall within the protection scope of the embodiments of the present application.

[0017] During the braking process of the vehicle, the deceleration is realized by the braking force, and the braking deceleration is related to the braking force and the mass. The simplified relationship is: braking force = mass * deceleration. In the current in-wheel motor, the br...

Abstract

The embodiment of the invention provides a hub motor, a tire, a carrying tool and a braking method of the carrying tool. The wheel hub motor determines stator parameters and rotor parameters of the wheel hub motor based on the mass, the maximum running speed, the minimum acceleration and the maximum deceleration of a carrying tool carrying the wheel hub motor, so that the wheel hub motor can output braking force for braking the carrying tool where the wheel hub motor is located and can also output braking force for braking the carrying tool where the wheel hub motor is located. The driving force for driving the carrying tool to run can also be output, the value of the braking torque corresponding to the maximum deceleration is n times of the value of the constant-speed running torque corresponding to the maximum running speed, and n is larger than a set threshold value. When the hub motor is arranged in a tire of a carrying tool, the controller can drive the hub motor to brake a motor bearing part such as the tire through the motor driver; moreover, the hub motor also has a conventional driving function, so that the hub motor provided by the embodiment of the invention can drive and brake the carrying tool at the same time.

Description

technical field [0001] The embodiments of the present application relate to the technical field of vehicles, and in particular, to an in-wheel motor, a tire, a vehicle, and a braking method for the vehicle. Background technique [0002] The wire-controlled chassis system is an important part of many vehicles (such as automobiles). Generally speaking, the wire-controlled chassis system has a longitudinal system (the so-called longitudinal refers to the direction consistent with the driving direction of the vehicle), and the longitudinal system also includes: Brake (brake) assembly and drive travel motor. Among them, the main part of the brake assembly can be realized by hydraulic brake components or pneumatic brake components. However, since these components are high-safety-level components of the vehicle, their manufacturing costs are relatively high. In addition, in order to cooperate with the main parts, further, oil circuits and brake control components required for bra...
