Description
Technical field
The utility model belongs to brake machinery field, and in particular to a kind of V-type brake block of band auxiliary return function
Return spring.
Background technique
Requirement of the country to vehicle oil consumption and vehicle exhaust discharge quantity at present is higher and higher, and vehicle factor is forced to require brake
To drag torque requirement higher and higher, and float type brake caliper assembly ratio used in motor vehicle braking system is very high, therefore,
The utility model is designed mainly for float type brake caliper assembly, since brake caliper assy drags torque according to existing means
Through without too big improvement space.
Utility model content
The purpose of this utility model is exactly to propose a kind of V-type brake block return spring of band auxiliary return function, can be had
Effect reduces brake block resistance to sliding, drags torque to be effectively improved.
To achieve the above object, the overall technological scheme of the utility model is as follows:
The utility model includes brake block return spring, and brake block return spring is V-shaped, the two sides of V-type spring open end
Two cylindrical portions are extended outward to form, the end of each cylindrical portion is bent to form bending part towards the direction far from brake disc, makes
One of bending part of motion block return spring is plugged into the circular hole on outside hung brake block assembly backboard, another bending
Portion is plugged into the external arc hole on inboard brake block assembly backboard, so as to be located at outside hung brake block total for brake block return spring
At between, inboard brake block assembly, the cylindrical portion and bending part of brake block return spring form elastic construction and make inside, outside
Brake pad assembly elastic recoil after brake release.
Preferably, the middle part between two bending parts of brake block return spring is connected by arc spring part.
Preferably, arc spring part is semicircular arc spring.
Preferably, cylindrical portion, bending part and arc spring part are structure as a whole.
Preferably, cylindrical portion, bending part and arc spring part are made of identical material.
The beneficial effects of the utility model are:
1) inboard brake block assembly and outside hung brake block assembly are in the V-type brake block return spring with auxiliary return function
Under the action of automatically disengage brake disc, to reduce brake block after brake release to the pressing friction power of brake disc, reduction is dragged
The purpose of stagnant torque reduces oil consumption and exhaust emissions amount.
2) V-type brake block return spring mounting means is similar to common brake block return spring and replacement restructuring is convenient,
Force value is stablized, and component is small and exquisite, and arrangement space is compact.

Fig. 4 is the schematic three dimensional views of the utility model installation.
In figure: 1. brake block return springs, 2. outside hung brake block assemblies, 3. inboard brake block assemblies, 11. cylindrical portions, 12.
Bending part.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described in further detail the utility model.
As shown in Figure 1 and Figure 2, brake block return spring 1 is V-shaped, and the two sides of V-type spring open end extend outward to form
The end of two cylindrical portions 11, each cylindrical portion 11 is bent to form bending part 12 towards the direction far from brake disc, and bending part 12 is used
In the backboard of brake pad assembly is carried out elastic recoil.
As shown in figure 3, one of bending part 12 of brake block return spring 1 is plugged into 2 backboard of outside hung brake block assembly
On circular hole in, another bending part 12 is plugged into the external arc hole on 3 backboard of inboard brake block assembly so that braking
Block return spring 1 is between outside hung brake block assembly 2, inboard brake block assembly 3, the cylindrical portion 11 of brake block return spring 1
Elastic construction, which is formed, with bending part 12 makes inside, outside hung brake block assembly elastic recoil after brake release.
In specific implementation, the middle part between two bending parts 12 of brake block return spring 1 is connected by arc spring part.
Arc spring part can be semicircular arc spring.
In specific implementation, cylindrical portion 11, bending part 12 and arc spring part be structure as a whole column and use identical material system
At.
The installation process of the utility model is as follows:
As shown in Figure 3 and Figure 4, brake pad assembly backboard, brake-caliper support, that brake disc belongs to brake pad assembly is original
Component.Brake-caliper support is fixed, and two bending parts 12 of brake block return spring 1 are limited respectively in the inside and outside of caliper
In the backboard external arc hole of side brake pad assembly, so that outside hung brake block assembly 2 and inboard brake block assembly 3 are limited by elasticity respectively
Position.1 one end of brake block return spring is against on inboard brake block assembly 3, and the other end is against on outside hung brake block assembly 2, braking
Block return spring has had certain magnitude of interference, within the scope of the value of elastic in design.Guarantee brake block return spring institute in this way
The value of elastic of generation can effectively offset the resistance to sliding of inside/outside side brake block and the resistance to sliding of caliper.
The elastic force of the brake block return spring of the utility model is to offset resistance to sliding when brake block return, but bullet
Spring force designs the resistance to sliding that should be slightly larger than brake block, needs to consider that the elastic force in later period increases problem.In this way in brake release
Afterwards, medial and lateral brake block can disengage brake disc surface automatically, and reduction drags moment values.
The course of work of the utility model is as follows:
After vehicle braking releases, piston is retracted, in the case where the bending part 12 of 1 side of brake block return spring acts on, inside system
The backboard of motion block assembly 3 automatically disengages brake disc, and the backboard of outside hung brake block assembly 2 is in 1 other side of brake block return spring
Bending part 12 automatically disengages brake disc under acting on.This reduces medial and lateral brake block after brake release to the pressure of brake disc
Friction-tight power reduces the purpose for dragging torque, reduces oil consumption and exhaust emissions amount.
Examples detailed above is the further explanation to the utility model, is not the specific restriction to the utility model, any right
Structure after the utility model simple transformation belongs to the protection scope of the utility model.
