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.
本发明提供了一种制动装置及车轮组件。在该制动装置中,不设置单独的球状锁定件,而是通过致动杆和导向套中的一者的凸部与另一者的凹部彼此配合,实现防止致动杆相对于导向套进行枢转的过程中致动杆脱出的功能。而且通过上述结构,致动杆的凸部和导向套的凹部之间的接触面积可以设置得足够大,即使在制动力矩较大的情况下也不会损坏致动杆和导向套。进一步地,根据本发明的制动装置相比背景技术中说明的制动装置的结构简单,易于装配。
