The model utility content
The purpose of the utility model is to overcome the deficiency of existing technology, and a kind of pressure spring type brake caliper is provided, and it is loosening that inside and outside braking plate is difficult for, and can not clash into each other with fixing frame and send abnormal sound.
The utility model solves the technological scheme that its technical problem adopted: a kind of pressure spring type brake caliper comprises fixing frame, pincers body, inside brake sheet, outer braking plate and piston assembly; The pincers body-fixed is on fixing frame, and this pincers body is provided with and is used for jaw and the opening of clamping brake disc towards the cylinder sleeve of jaw, and inside and outside braking plate is located at the both sides of jaw respectively, and the piston assembly sliding sleeve is in cylinder sleeve; Also comprise stage clip, this stage clip is loaded on the madial wall at corresponding its jaw place of pincers body, and supports inside braking plate and outer braking plate simultaneously.
Said inside and outside braking plate has two lugs respectively, and said fixing frame has four containing grooves of two lugs that are used for ccontaining inside and outside braking plate; Each lug of said inside and outside braking plate is placed in respectively in the corresponding containing groove, and also is respectively equipped with the yoke spring between each lug and the corresponding containing groove; Said stage clip piece shape structure; And the edge of the left and right sides of this sheet body structure is respectively towards the direction turnover of the madial wall of said pincers body; Be formed for flange, the corresponding respectively sidewall that supports to each lug of said inside and outside braking plate of the corner point of two flange of this sheet body structure against said inside and outside braking plate.
The madial wall middle part of said pincers body is provided with an opening, and the stage casing of said body structure is protruding grand towards the opening direction of said pincers body, and is limited in this opening; The left and right sides at corresponding its protruding grand position of said body structure also is respectively equipped with an intermediate plate, and each intermediate plate supports the madial wall to said pincers body respectively.
Compare with the brake caliper of existing technology, the beneficial effect of the utility model is, because it is equipped with stage clip at the pincers body to the madial wall at corresponding its jaw place; And this stage clip supports to inside and outside braking plate simultaneously, and promptly stage clip provides the restraining force of a direction towards the jaw outside to inside and outside braking plate respectively, makes the sidewall of each lug of inside and outside braking plate can keep contacting with the yoke spring; Thereby it is loosening that inside and outside braking plate is difficult for; And in the car brakeing process, can not rotate and squint, thereby bump can not take place and send abnormal sound in inside and outside braking plate with fixing frame with brake disc; And after the braking, the return better effects if of inside and outside braking plate.
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain; But a kind of pressure spring type brake caliper of the utility model is not limited to embodiment.

Embodiment
Embodiment sees also Fig. 2-shown in Figure 4, and a kind of pressure spring type brake caliper of the utility model comprises fixing frame 1, pincers body 2, inside brake sheet 8, outer braking plate 9, piston assembly and stage clip 3.Pincers body 2 is fixed on the fixing frame 1; This pincers body 2 is provided with and is used for jaw and the opening of clamping brake disc towards the cylinder sleeve 21 of jaw; Inside and outside braking plate 8,9 is located at the both sides of jaw respectively; Piston assembly specifically comprises piston 5, oil seal washer 6 and dust ring 7, and piston 5 sliding sleeves are in cylinder sleeve 21, and oil seal washer 6 and dust ring 7 are sealed and matched respectively between the inwall of the outer wall of piston 5 and cylinder sleeve 21.Stage clip 3 is loaded on the madial wall at pincers body 2 corresponding its jaw places, and supports inside braking plate 8 and outer braking plate 9 simultaneously.
Wherein, the left and right sides of inside and outside braking plate 8,9 is respectively equipped with a lug 81,91, and fixing frame 1 has four containing grooves 11 of two lugs that are used for ccontaining inside and outside braking plate; Each lug of inside and outside braking plate 8,9 is placed in respectively in the corresponding containing groove 11, and also is respectively equipped with yoke spring 4 between each lug and the corresponding containing groove.Above-mentioned stage clip 3 piece shape structures; And the edge of the left and right sides of this sheet body structure turns down towards the direction of the madial wall that clamps body 2 respectively; Be formed for flange 31, the corresponding respectively sidewall that supports to each lug of inside and outside braking plate 8,9 of the corner point of two flange 31 of this sheet body structure against inside and outside braking plate.
The madial wall middle part of above-mentioned pincers body 2 is provided with an opening 22, and the stage casing of above-mentioned body structure is protruding grand towards the opening direction of this pincers body 2, and is limited in this opening 22 places; The left and right sides at corresponding its protruding grand position of said body structure also is respectively equipped with an intermediate plate 32, and each intermediate plate 32 supports the madial wall to pincers body 2 respectively.
A kind of pressure spring type brake caliper of the utility model; When vehicle carries out brake, can set up brake hydraulic in the cylinder sleeve 21 of its pincers body, make piston 5 promote inside brake sheet 8 and press to brake disc; Produce reaction force at cylinder sleeve 21 rear portions of pincers body simultaneously; Under the effect of this reaction force, pincers body 2 moves backward and drives outer braking plate 9 presses to brake disc, thereby forces the brake disc spline.
See also shown in Figure 4; After stage clip 3 is contained in the madial wall at pincers body 1 corresponding its jaw place; About this stage clip 3 corner point of two flange 31 respectively internally two lugs 81 of braking plate the restraining force of a F direction is provided, two lugs 81 of this inside brake sheet are supported to yoke spring 4 along the F direction respectively, so can make two lugs 81 of inside brake sheet be affixed to yoke spring 4 respectively all the time; And in the process of car brakeing, inside brake sheet 8 can not squint along the F direction with the rotation of brake disc.In other words, under the effect of stage clip 3, inside brake sheet 8 can not send abnormal sound with fixing frame 1 mutual bump because of skew takes place along F.In like manner, about stage clip 3 corner point of two flange 31 also respectively externally two of braking plate lugs 91 restraining force of a F direction is provided, make it be difficult for loosening and squint.In addition, because under the constraint of stage clip 3, inside and outside braking plate 8,9 can not take place along the action of F direction skew in braking process, thereby after the braking, inside and outside braking plate 8,9 can carry out return by original track respectively, thereby its return effect is better.
The foregoing description only is used for further specifying a kind of pressure spring type brake caliper of the utility model; But the utility model is not limited to embodiment; Every technical spirit according to the utility model all falls in the protection domain of the utility model technological scheme any simple modification, equivalent variations and modification that above embodiment did.
