Abstract
The invention discloses a disk type brake. The disk type brake comprises a brake disc and clamps located on the two sides of the brake disc, wherein a friction plate is arranged on the inner side of each clamp. The disk type brake is characterized in that each friction plate is a friction block array formed by a plurality of friction blocks, and a squeezing part is arranged in each clamp and squeezes the corresponding friction block array to enable different numbers of friction blocks to make contact with the brake disc and generate friction along with the change of the stroke of the squeezing part. According to the disk type brake, an existing friction block is changed into the friction block array formed by a plurality of friction blocks, braking force is increased gradually by increasing the number of friction blocks making contact with the brake disc gradually, so that a wide braking force adjusting range is obtained, braking force is increased gradually within a wide range, and riding stability and comfort are improved. Meanwhile, the disk type brake is simple in structure and low in manufacturing cost.
Description
Technical field
The invention belongs to vehicle brake technology field, particularly relate to a kind of disk type brake being applicable to electric motor car.
Background technique
The brake that electric motor car is conventional is drum brakes, has braking force large, the advantage of good braking effect.But along with the speed of a motor vehicle of electric motor car and the increase of weight, required braking force is corresponding increase also, the brake drum heating of drum brakes, finally causes gap to become large, brakes elongated, easily cause brake failure.Disk type brake is with static brake disc, clamps braking disc with tyre rotation to produce frictional force, the braking device that the speed that turns a wheel reduces.Have good heat dissipation effect, seldom have heat fade sign, long-time braking can keep the advantage of good braking effect.Current disk type brake is also widely used in electric motor car.But the braking distance of disk type brake is short, the defect that brake-force control scope is little, make electric motor car under the prerequisite ensureing braking force, reduce the stationarity and travelling comfort of riding, phenomenon of nodding during brake is serious.And more often the object of skidding is slowed down, therefore, need braking force to have a wider progressive process, improve the stationarity and travelling comfort of riding.
Summary of the invention
The object of the invention is to provide for the defect of prior art that a kind of structure is simple, brake-force control wide ranges, brakes mild disk type brake.
The present invention for achieving the above object, adopts following technological scheme:
A kind of disk type brake, comprise brake disc and the clamp being positioned at brake disc both sides, described caliper inboard is provided with friction plate, it is characterized in that: described friction plate is the brake pad array of multiple brake pad composition, extruder member is provided with in clamp, along with the stroke of extruder member changes, extruder member extrusion friction block array, makes brake pad and the brake disc contact friction of varying number.By brake pad and the brake disc contact friction of varying number, produce different braking force, increase brake-force control scope.
It is further characterized in that: described clamp have clamp shell, and described extruder member and brake pad array are arranged in described clamp shell, and described extruder member is the bevelled extrusion block of head tool, and described extrusion block is pressed on clamp shell rear portion; Described brake pad array longitudinal arrangement, one end is pressed on the inclined-plane of extrusion block head, and along with extrusion block moves up, the block that is squeezed extrudes the brake pad increased number stretched out.Up along with extrusion block, the brake pad quantity of braking and braking force also increase gradually.
Further: described extrusion block and brake pad array contact face have gradient from top to bottom.The gradient of surface of contact can ensure that the pressure between brake pad and brake disc also increases thereupon while brake area increases.
Preferred: described extrusion block and brake pad array contact face gradient are 1-3 degree.
Described extruder member drives stroke change by oil hydraulic cylinder or braking string.
Preferred: described brake pad array is staggered by the brake pad of two kinds of unlike materials and forms, the compression ratio of two kinds of materials is different, and the brake pad length of the larger material of compression ratio is slightly larger than the brake pad length of the less material of compression ratio.This structure can ensure first to carry out friction catch at the brake pad of the less larger material of compression ratio of braking initial stage braking force, and play the effect of deceleration, the braking later stage, the brake pad acting in conjunction of two kinds of materials, braking force sharply increases, and ensures braking effect.
The brake pad of two kinds of materials is respectively rubber friction block and semi-metallic brake pad.
Existing brake pad is become the brake pad array of multiple brake pad composition by the present invention, by increasing the brake pad quantity contacted with brake disc gradually, increase braking force gradually, thus obtain the brake-force control scope of a relative broad range, braking force has a wider progressive process, improves the stationarity and travelling comfort of riding.Meanwhile, structure of the present invention is simple, low cost of manufacture.

Fig. 2 is original state schematic diagram of the present invention.
Embodiment
A disk type brake as shown in Figure 1, 2, comprise brake disc 1 and the clamp being positioned at brake disc 1 both sides, described clamp comprise clamp shell 2, extruder member and brake pad array 3, and described extruder member and brake pad array 3 are arranged in described clamp shell 2.Described extruder member is the bevelled extrusion block 4 of head tool, and described extrusion block 4 is pressed on clamp shell 2 rear portion; Described brake pad array 3 longitudinal arrangement, one end is pressed on the inclined-plane of extrusion block 4 head, and along with extrusion block 4 moves up, the block 4 that is squeezed extrudes the brake pad increased number stretched out.Up along with extrusion block 4, the brake pad quantity of braking and braking force also increase gradually.As shown in Figure 2, the brake pad array 3 low portion brake pad of the block 4 that is squeezed extruding and brake disc 1 contact friction, brake, brake pad array 3 upper part brake pad does not contact with brake disc 1.
Described extrusion block 4 and brake pad array 3 surface of contact have the gradient of 1-3 degree from top to bottom.The gradient of surface of contact can ensure that the pressure between brake pad and brake disc 1 also increases thereupon while brake area increases.
Preferred: described brake pad array 3 is staggered by the brake pad of rubber friction block 31 and semi-metallic brake pad 32 two kinds of unlike materials and forms, and rubber friction block 31 length is slightly larger than semi-metallic brake pad 32 length.This structure can ensure that first the rubber friction block 31 braking initial stage braking force is less carries out friction catch, and play the effect of deceleration, the braking later stage, the brake pad acting in conjunction of two kinds of materials, braking force sharply increases, and ensures braking effect.
Described extruder member can drive stroke change by oil hydraulic cylinder or braking string.
Existing brake pad is become the brake pad array of multiple brake pad composition by the present invention, by increasing the brake pad quantity contacted with brake disc gradually, increase braking force gradually, thus obtain the brake-force control scope of a relative broad range, braking force has a wider progressive process, improves the stationarity and travelling comfort of riding.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
