Abstract
The utility model discloses a kind of augmented wheel brake, main contents are: comprise braking bottom board, rear brake shoe, reinforcement cover, rear support pin, front support pin, reinforcement pin, fore brake and brake cylinder, it is characterized in that, described rear support pin and front support pin are arranged on braking bottom board, rear brake shoe to be arranged on rear support pin and can to rotate around rear support pin, fore brake to be arranged on front support pin and can to rotate around front support pin, reinforcement cover is rigidly attached in vehicle bridge, braking bottom board empty set is in vehicle bridge and can around axle windup, brake cylinder left end is connected on fore brake afterbody right side, brake cylinder right-hand member is connected on rear brake shoe afterbody left side, reinforcement pin is stuck in rear brake shoe, in the groove that reinforcement cover and fore brake are formed.The utility model cost is low, reasonable stress, wearing and tearing all with and brake safe is reliable, braking effect is remarkable.
Description
Technical field
The utility model relates to break technical field, particularly relates to a kind of augmented wheel brake.
Background technique
General wheel drag complicated structure, and be due to stressed unreasonable, cause wearing and tearing uneven, have a strong impact on braking effect and brake life, even the life safety of serious threat driver, the requirement of Medium or severe type automobile brake can not be met.
Model utility content
According to above deficiency, the utility model provides that a kind of cost is low, reasonable stress, wearing and tearing all with and the reliable augmented wheel brake of brake safe.
For achieving the above object, the utility model augmented wheel brake, main contents are: comprise braking bottom board, rear brake shoe, reinforcement cover, rear support pin, front support pin, reinforcement pin, fore brake and brake cylinder, it is characterized in that, described rear support pin and front support pin are arranged on braking bottom board, described rear brake shoe to be arranged on rear support pin and can to rotate around rear support pin, described fore brake to be arranged on front support pin and can to rotate around front support pin, described reinforcement cover is rigidly attached in vehicle bridge, described braking bottom board empty set is in vehicle bridge and can around axle windup, described brake cylinder left end is connected on fore brake afterbody right side, described brake cylinder right-hand member is connected on rear brake shoe afterbody left side, described reinforcement pin is stuck in rear brake shoe, in the groove that reinforcement cover and fore brake are formed.
As preferably, described rear brake shoe and fore brake are all provided with brake drum and brake check spring.
As preferably, described reinforcement puts end face and is processed with " V " shape notch.
As preferably, described rear brake shoe and fore brake are all sector structure.
As preferably, on described braking bottom board, central position is processed with cylindrical hole.
The utility model beneficial effect is: cost is low, reasonable stress, wearing and tearing all with and brake safe is reliable, braking effect is remarkable.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Description of reference numerals:
1-braking bottom board, brake shoe after 2-, 3-reinforcement cover, 4-rear support pin, 5-front support pin, 6-reinforcement pin, 7-fore brake, 8-brake cylinder.
Embodiment
Below in conjunction with drawings and Examples, the utility model embodiment is described:
These system main contents are: comprise braking bottom board 1, rear brake shoe 2, reinforcement cover 3, rear support pin 4, front support pin 5, reinforcement pin 6, fore brake 7 and brake cylinder 8, it is characterized in that, described rear support pin 4 and front support pin 5 are arranged on braking bottom board 1, described rear brake shoe 2 to be arranged on rear support pin 4 and can to rotate around rear support pin 4, described fore brake 7 to be arranged on front support pin 5 and can to rotate around front support pin 5, described reinforcement cover 3 is rigidly attached in vehicle bridge, described braking bottom board 1 empty set is in vehicle bridge and can around axle windup, described brake cylinder 8 left end is connected on fore brake 7 afterbody right side, described brake cylinder 8 right-hand member is connected on rear brake shoe 2 afterbody left side, described reinforcement pin 6 is stuck in rear brake shoe 2, in the groove that reinforcement cover 3 and fore brake 7 are formed.
When implementing braking, the pulling force that fore brake 7 and rear brake shoe 2 overcome return spring under brake cylinder 8 thrust outwards opens; Before brake shoe contacts with brake drum, reinforcement pin 6, reinforcement cover 3, braking bottom board 1 and the active force between brake shoe and vehicle bridge disappear, brake shoe and braking bottom board 1 can rotate freely in vehicle bridge, without active force between reinforcement pin 6 and reinforcement cover 3, reinforcement pin 6 still drops in the middle of the V-type face of reinforcement cover 3; After brake shoe contacts with brake drum, under the effect of brake drum frictional force, the direction rotated along brake drum is rotated by brake shoe and braking bottom board, when after after brake shoe 2 contacts with reinforcement pin 6, just force reinforcement pin 6 along the V-type of reinforcement cover 3 towards left movement until contact with fore brake 7, at brake drum under the turning effort of brake shoe friction torque, reinforcement pin 6 is just tightly squeezed at rear brake shoe 2, between reinforcement cover 3 and fore brake 7, fore brake 7 and rear brake shoe 2 and braking bottom board 1 stop operating.
After loosening the brake, the distress resolves in brake cylinder 8, under the effect of return spring pulling force, brake shoe and brake drum disengage, brake release; Under the effect of reinforcement cover 3, the rotations such as brake shoe and braking bottom board 1, reinforcement pin 6 moves right, until break each several part return along the V-type face of reinforcement cover 3 simultaneously.
By reference to the accompanying drawings the utility model preferred implementation is explained in detail above, but the utility model is not limited to above-mentioned mode of execution, in the ken that those of ordinary skill in the art possess, can also make a variety of changes under the prerequisite not departing from the utility model aim.
Do not depart from design of the present utility model and scope can make many other and change and remodeling.Should be appreciated that the utility model is not limited to specific mode of execution, scope of the present utility model is defined by the following claims.
