Abstract
The utility model discloses an integral type fixed aluminum alloy braking caliper used for braking automobiles, which comprises a caliper body (1), a piston (2), a packing ring (4), a friction block (7), a high-pressure oil tube (15), a locating pin shaft (17) and a bleed screw (18), wherein the caliper body (1) is in integral form, the friction block (7) is installed on a friction block bearing plate (6), a damping shrapnel (10) is installed on the top of the friction block bearing plate (6), and shrapnel locating screw bolts are installed on the damping shrapnel (10) and on the top of the caliper body (1). The integral type fixed aluminum alloy braking caliper improves the strength of integral caliper body, enables the structure of the braking caliper to be more compact and simple, furthest and reasonably utilizes the automobile chassis space, and can integrate the three functions of foot brake, parking brake and emergency brake, thereby, the braking efficiency of the brake is greatly improved and the driving safety is strongly guaranteed.
Description
One, technical field
The utility model relates to the disk type braker that a kind of automobile brake is used, and particularly relates to the fixed pattern brake calipers in the disk type braker that a kind of automobile brake uses.
Two, background technique
Automobile brake perfrmance is a very important index of stability of automobile, Security, and wherein brake calipers is very important critical component in the automobile brake perfrmance.At present, the fixed pattern brake calipers adopts cast iron materials, and its caliper is split type, is formed by connecting by bolt by left caliper and right caliper body, and product structure is not compact, and brake pad fixes by alignment pin with only being connected of caliper, and it is not very good braking stationarity.It has functions such as service brake and emergency brake, and parking braking then realizes by halting mechanism in addition.These have all influenced the technical performance and the usability of fixed pattern brake calipers.
Three, model utility content
The purpose of this utility model is to overcome above-mentioned deficiency, service brake, parking braking and emergency brake function can be concentrated on that one, structure are simplified, steady qualitative good whole type positioning aluminium alloy braking clamp and provide a kind of.
The purpose of this utility model realizes by following technical solution: a kind of integral type positioning aluminium alloy braking clamp, comprise caliper, piston, seal ring, brake pad, high-pressure oil pipe, alignment pin, bleed screw, described caliper is an integrated type, described brake pad is contained on the brake pad backing plate, on the top of brake pad backing plate, damping spring plate is housed, on damping spring plate, the top of caliper is equipped with the shell fragment holding down bolt.
After adopting the utility model, caliper is adopted integral design and processing, can improve caliper bulk strength, make brake calipers more compact structure, more simplify, to greatest extent, reasonably utilize the automobile chassis space; Use damping spring plate, made brake pad move more steadily, can integrate service brake, parking braking and three functions of emergency brake.Thereby improved the braking effect of break, made the traffic safety of automobile obtain powerful guarantee.
Four, description of drawings
Below in conjunction with accompanying drawing and mode of execution the utility model is described in further detail.
Fig. 1 is the structural representation of the utility model integral type positioning aluminium alloy braking clamp.
Fig. 2 is the C-C sectional view of Fig. 1.
Five, embodiment
With reference to Fig. 1, Fig. 2 as can be known, the integral type positioning aluminium alloy braking clamp that the utility model automobile brake is used, comprise caliper 1, piston 2, seal ring 4, brake pad 7, high-pressure oil pipe 15, alignment pin 17, bleed screw 18, described caliper 1 is an integrated type, described brake pad 7 is contained on the brake pad backing plate 6 (the brake pad backing plate is between piston and the brake pad), damping spring plate 10 is housed on the top of brake pad backing plate 6, on damping spring plate 10, shell fragment holding down bolt 8 and screw 9 (utilize the shell fragment holding down bolt to push down damping spring plate, the shell fragment holding down bolt is used screw lock again) are equipped with in the top of caliper 1.Wherein, high-pressure oil pipe 15 is equipped with the connecting part of caliper 1 and is connected plug screw 16, can be with rubber pillar 14 outside the high-pressure oil pipe 15; Has filler opening 12 on the caliper 1, the external oil-feed of this filler opening 12 system 11; Be with bleed screw dust-proof cover 19 on the bleed screw 18.
In order to prevent entering of extraneous dust, between described brake pad backing plate 6, piston 2 and caliper 1, be provided with dust-proof cover 5.In order to alleviate the weight of caliper, make it have better heat radiating effect, and reduce its process time, manufacturing process flow, improve the high-precision surface quality of caliper and good external frame, described caliper 1 adopts all aluminium alloy material; For the piston that makes the caliper both sides combine with brake pad backing plate (and brake pad) tightr, braking effect is better, described piston 2 (comprising left piston shown in Figure 22, right piston 13) adopts distortion aluminium material (6061 types, meeting the GB/T3190-1996 GB requires), in caliper 1, during described install, between the piston 2 (left piston shown in Figure 2) in the outside and brake pad backing plate 6, be provided with piston packing 3, described piston packing 3 adopts phenolaldehyde moulding compound (black, model are PF2D1-8511) material.In order to make the brake pad easy accessibility, to be easy to change, described alignment pin 17 is a some cylindricality, and is divided in around the bottom of caliper 1 (being that alignment pin is four), the brake pad top is contained between these four alignment pin, as shown in Figure 1; Technique known is that brake pad is installed on the alignment pin, and alignment pin is two microscler axostylus axostyles, and brake pad moves along alignment pin.
Working principle of the present utility model is: automobile braking mechanism makes automobile master cylinder input brake liquid by the control of automobile electrically-controlled circuit, brake fluid is from 11 inputs of oil-feed system, enter caliper through filler opening, when producing oil pressure seal ring 4 is worked, brake fluid is input to the opposite side of caliper by high-pressure oil pipe 15 in caliper, after producing certain oil pressure, promote the reversing motion of piston to pressurized, move together by piston promotion brake pad backing plate 6 and brake pad 7, the brake pad 7 of brake disc both sides is embraced brake disc, thereby make the car deceleration in travelling or stop to travel.Parking braking function is after vehicle stops to travel, and operation electronics knob is passed to the brake pad that is distributed in the brake disc both sides with power and brake disc is embraced, and it is as you were that automobile is remained on.Thereby can cancel the manual parking brake rod in the compartment, stopping brake just can realize that by an electronics knob within reach Safety performance promotes greatly.The emergency brake function is to have in service brake under the situation of place inefficacy, and operation electronics knob is passed to the brake pad that is distributed in the brake disc both sides with power and brake disc is embraced, and vehicle is stopped in a suitable segment distance.
