Description
Technical field
The utility model belongs to automobile manufacture field, more particularly to a kind of brake component.
Background technology
Safety component of the brake as running car, plays a crucial role in car deceleration and braking, makes
Dynamic hoof is then the important component of brake.At work, cam acts on roller brake, makes roller shaft and axis hole phase
Support, roller shaft promotes gusset and hoof plate to be flared out, so that the friction plate on hoof plate produces friction simultaneously with brake drum
Play the role of braking or deceleration.
During this, axis hole is subject to the extruding of roller shaft easily to produce abrasion for a long time, and the power that axis hole is subject to can be finally anti-
Should be on gusset and hoof plate so that gusset and hoof plate are easy to be deformed, and the deformation of hoof plate and gusset can shorten brake-shoe
Service life and influence braking or the slowing effect of brake, the personal safety of entail dangers to driver is gone back when serious.
Utility model content
The purpose of this utility model is to provide a kind of high rigidity heavy-duty car drum-type to weld brake-shoe, to solve background skill
The problem of brake-shoe service life is shorter in art.
In order to achieve the above object, the base case of the utility model provides the welding braking of high rigidity heavy-duty car drum-type
