Description

A kind of brake calipers securing device

Technical field

The utility model belongs to braking system technical field, relates to a kind of brake calipers securing device.

Background technique

Caliper disc brake is get its shape and gain the name, it is by hydraulic control, main parts size has brake disc, wheel cylinder, brake calipers, oil pipe etc., alloy steel for braking discs manufacture is also fixed on wheel, with vehicle wheel rotation, wheel cylinder is fixed on the base plate of break and maintains static, two friction plates on brake calipers are contained in respectively the both sides of brake disc, the hydraulic pressure that the piston of wheel cylinder is transported by oil pipe, promote friction plate and press to brake disc generation friction catch, it just looks like to vise the plate in rotation with pliers that action is got up, and forces it to stop the same.

Existing brake calipers is provided with brake disc that can translation on caliper on caliper, on caliper, be installed with outer braking plate, inside brake sheet is installed on brake disc, movement by brake disc regulates the distance between outer braking plate and inside brake sheet to reach the object of brake, guide rod is generally installed on brake disc, on outer braking plate, pilot hole is installed, guide rod inserts in pilot hole and moves in pilot hole, balance while reaching brake by guide rod and pilot hole between outer braking plate and brake disc, prevent that the two is because friction produces displacement, and guide rod is in pilot hole in moving process, under braking action, between guide rod and pilot hole, can there is hard collision, and then larger vibration and the sound of generation, not only can make outer braking plate and guide rod friction serious and impaired, and sound too conference form noise.

In sum, for the defect of above-mentioned brake calipers, need to design a kind of brake calipers that can reduce the wearing and tearing of outer braking plate in braking process and can reduce sound.

Model utility content

The purpose of this utility model is the problems referred to above that exist for prior art, has proposed the degree of wear less and sound little brake calipers of a kind of outer braking plate in braking process.

The purpose of this utility model can realize by following technical proposal: a kind of brake calipers securing device, comprise caliper and be flexibly connected with caliper and can be with respect to the brake disc of caliper translation, on caliper, be fixedly installed outer braking plate, on brake disc, be fixedly installed with brake disc and move and approach or away from the inside brake sheet of outer braking plate, on described brake disc, be provided with guide rod, described outer braking plate one end has mounting plate and the corresponding pilot hole that offers on mounting plate, guide rod inserts in pilot hole and moves in pilot hole, on described guide rod, being arranged with firm and firm is positioned between brake disc and outer braking plate, described firm seat one end is provided with U-shaped shell fragment and two U-shaped intermediate plates and U-shaped shell fragment between two U-shaped intermediate plates, on mounting plate outer side wall, cave inward and be formed with breach and be formed with respectively lug in breach both sides, described two U-shaped intermediate plates are clipped in respectively on two lugs, described U-shaped shell fragment is against in breach.

In above-mentioned a kind of brake calipers securing device, described firm seat both sides upwards convex with respectively banking stop, described mounting plate between two banking stops and banking stop madial wall be affixed on mounting plate outer side wall.

Compared with prior art, the utlity model has following beneficial effect:

1, in the utility model, firm cover for seat is located on guide rod and between outer braking plate and brake disc, under the elastic force effect of U-shaped shell fragment, U-shaped shell fragment is positioned at breach and is against all the time on mounting plate, played on the one hand buffer function, brake calipers is when braking, the deformation of U-shaped shell fragment has consumed the active force of outer braking plate, because the moment that braking plate contacts with guide rod is in addition cushioned, prevent the two rigid contact, wearing and tearing when effectively having reduced outer braking plate and moving on guide rod, the sound when also having reduced outer braking plate and contacting with guide rod, on the other hand, U-shaped shell fragment is positioned at breach, for whole firm seat, played position-limiting action, prevent firm seat contacting to both sides rotation disengaging and mounting plate centered by guide rod, make firm seat contact and play all the time buffer function with mounting plate.

2, two U-shaped intermediate plates are clamped two lugs of mounting plate, when preventing that firm seat from rotating, can prevent that firm seat from departing from mounting plate in vertical direction, and firm seat is adjacent to mounting plate all the time, effectively raise the whole shock-absorbing capacity of firm seat.
