Abstract
The invention discloses a floating caliper disc brake with a brake pad wear warning and reminding function. The floating caliper disc brake comprises brake calipers and a brake disc. A liquid inlet and a piston cavity are formed in the brake calipers. A fixed brake pad is arranged on the brake calipers. A piston is arranged in the piston cavity. A movable brake pad is arranged at the piston. A first groove is formed in the movable brake pad. A first screw is arranged at the first groove. The head of the first screw is positioned in the first groove. A second groove is formed in on one side, facing the brake disc, of the fixed brake pad. A second screw is arranged at the second groove. The head of the second screw is positioned in the second groove. The floating caliper disc brake adopting the scheme has the effects that according to the actual allowable wear extents of the brake pads, the allowable wear extents are converted into the size differences between the grooves and the heads of the screws, so that when the allowable wear extents of the brake pads are maximal, the heads of the screws just protrude out from the brake pads, and when the heads of the screws are in contact with the brake disc, a harsh squeal is generated to remind a driver to replace the brake pads.
Description
Technical field
The present invention relates to disc brake with floating caliper, be specially a kind of disc brake with floating caliper with brake pads wear prompt functions.
Background technique
In Motor Vehicle Braking Procedure, break is to provide the vitals of braking force, caliper disc brake because of its heat dispersion strong, good thermal stability and be widely used on car and pick up truck, disc brake with floating caliper is then most popular a kind of caliper disc brake.
The disc brake with floating caliper of current use is when braking, the brake slipper of brake disc both sides realizes braking from both sides clamping brake disc respectively, the disc brake with floating caliper of this structure in use for some time, wear phenomenon is there is in brake slipper by inevitable, and when brake pads wear to a certain extent after, its Braking efficiency will weaken greatly, if replacing brake slipper now not in time, vehicle will be made can not to produce due braking force when needs are braked, there is great potential safety hazard.
Summary of the invention
The invention is intended to provide a kind of when brake pads wear to a certain extent time, break can send the disc brake with floating caliper with brake pads wear prompt functions that ear-piercing shriek prompting driver changes brake slipper.
The disc brake with floating caliper with brake pads wear prompt functions in this programme, comprise brake calipers and brake disc, brake calipers float across the both sides at brake disc, the piston cavity brake calipers of brake disc side offering inlet opening and communicate with inlet opening, the brake calipers of brake disc opposite side is provided with fixing brake slipper, piston is provided with in piston cavity, piston place is also provided with movable brake slipper, movable brake slipper offers the first groove towards brake disc side, first groove is provided with the first screw, the thread section of the first screw passes the first groove and movable brake slipper and piston is linked together, the head of the first screw is positioned at the first groove, fixing brake slipper offers the second groove towards brake disc side, second groove is provided with the second screw, the thread section of the second screw passes the second groove and fixing brake slipper and brake calipers is linked together, the head of the second screw is positioned at the second groove.
The principle of this programme is: during braking, brake fluid enters piston cavity from inlet opening and promotes piston and moves to brake disc direction together with movable brake slipper, when movable brake slipper and brake disc offset, brake disc is to piston active force, this active force makes piston move together with brake calipers integral inverted direction, the fixing brake slipper of braking and movable brake slipper press on the disc brake rotor simultaneously, and brake disc is braked.
Because brake disc realizes braking by the frictional force of itself and brake slipper, therefore in use for some time, the wearing and tearing that movable brake slipper and fixing brake slipper all will occur in various degree, when activity brake pads wear to a certain extent time, the first screw head being positioned at movable brake slipper first groove will protrude from movable brake slipper, in like manner, fixing brake pads wear to a certain extent time, the second screw being positioned at fixing brake slipper second groove also will protrude from fixing brake slipper, when again braking, first screw head and the second screw head offset with brake disc respectively, now break will send ear-piercing shriek, driver is reminded to change brake slipper in time.
The effect of this programme is: by offering groove on brake slipper, and the screw head being used for brake slipper connection is positioned in groove, according to the admissible wear extent of actual brake slipper, the wear extent of permission is converted into the difference of groove and screw head size, therefore when brake slipper reaches the wear extent of maximum permission, screw head just in time will protrude from brake slipper, when screw head and brake disc, produce ear-piercing shriek, driver is reminded to change brake slipper, therefore this programme is compared with traditional disc brake with floating caliper: on the one hand when brake pads wear to a certain extent time energy automatic alarm, the Placement installation and removal of screw are all very convenient on the other hand.
Further, fixing be also provided with brake shoe between brake slipper and brake calipers, brake shoe can effectively reduce impact force when fixing brake slipper and brake disc are fitted.
Further, piston area is also provided with the 3rd groove to inlet opening place, 3rd groove communicates with piston cavity, when brake fluid enters in piston cavity from inlet opening, partial brake liquid will flow through the 3rd groove communicated with piston cavity, and the brake fluid flowing through the 3rd groove can take away the heat at piston place on the one hand, and the brake fluid absorbing heat on the other hand produces larger pressure by generation piston cavity, this pressure by more tight for the laminating made between brake slipper and brake disc, thus improves the Braking efficiency of break.
Further, the fitting surface place of piston and brake calipers is also provided with elastic seal ring, the face leakage that elastic seal ring can prevent brake fluid from coordinating from piston with brake calipers on the one hand, the elasticity of elastic seal ring can make piston drive brake slipper to be separated with brake disc in time upon completion of the braking on the other hand.
