Problems solved by technology

[0003] However, the contact area between the locking piece, the actuating rod and the guide sleeve is too small, so when a large braking torque is generated, the pressure between the locking piece, the actuating rod and the guide sleeve will be too large, and it will be easily damaged. Actuation rod and guide sleeve
Moreover, the connection structure and the installation process of the locking piece, the actuating rod and the guide sleeve are also complicated.

Abstract

The invention provides a brake device and a wheel assembly. In the brake device, a single spherical locking piece is not arranged, and a convex part of one of an actuating rod and a guide sleeve is matched with a concave part of the other one of the actuating rod and the guide sleeve so that the function of preventing the actuating rod from being disengaged in the pivoting process of the actuatingrod relative to the guide sleeve can be achieved. Through the structure, the contact area between the convex part of the actuating rod and the concave part of the guide sleeve can be set to be largeenough, and therefore the actuating rod and the guide sleeve cannot be damaged even under the condition of large braking torque. Furthermore, compared with a brake device described in the background art, the brake device provided by the invention is simple in structure and easy to assemble.

Description

technical field [0001] The invention relates to the field of braking of vehicles, more particularly to a braking device for a vehicle and a wheel assembly including the braking device. Background technique [0002] For wheel assemblies for vehicles, in particular two-wheeled vehicles such as electric scooters, it is necessary to integrate an adapted braking device into the wheel assembly as compactly as possible. In this braking device, the actuating rod for transmitting the actuating force and the guide sleeve are locked by a separate spherical locking member, so as to prevent the actuating rod from coming out during the pivoting process relative to the guide sleeve. [0003] However, the contact area between the locking piece, the actuating rod and the guide sleeve is too small, so when a large braking torque is generated, the pressure between the locking piece, the actuating rod and the guide sleeve will be too large, and it will be easily damaged. Actuation lever and gu...
