The invention discloses a fixing device used for enhancing the connection strength of a brake and a bridge, and a fixing method of the fixing device. The fixing device comprises an axle housing. The two ends of the axle housing are provided with a flange plate and a brake backing plate, the brake backing plate is sleeved from the two ends of the axle housing via an axle hole of the brake backing plate to be installed and connected with the flange plate, the fixing device also comprises a meshing mechanism used for meshing the brake backing plate and the installation surface of the flange plate, and an elastic clamping mechanism is arranged between the brake backing plate and the axle housing. According to the invention, the force transmission which is traditionally borne only by fixing bolts is changed into the way of being borne by both the fixing bolts and end face tooth structures, the bearing capacity of the fixing bolts on the brake backing plate is reduced, thus the connection strength of the brake backing plate and the flange plate is higher, and the connection reliability is better. Fracture failures of bolts caused by insufficient intensity of installation bolts of the brake backing plate are removed, and hidden dangers caused by fracture of the installation bolts of the brake are eliminated.
Description
technical field [0001] The invention belongs to the technical field of vehicle axles, and in particular relates to a fixing device and a fixing method for enhancing the connection strength of a brake and an axle. Background technique [0002] The vehicle braking system is an important part of the vehicle and the key to ensuring the normal driving of the vehicle. Its working principle is to use the mutual friction between the non-rotating elements connected to the frame and the rotating elements connected to the wheels (or drive shafts) to resist the turning or tendency of the wheel to turn. The brake system is mainly composed of brake base plate, brake drum, brake shoe, return spring, positioning pin and other components. The brake base plate is installed on the fixed position of the axle, and it is fixed. There are brake shoes, return springs and positioning pins on it, and it bears the rotational torque during braking. [0003] The existing way of fixing the brake base p...
