Abstract

The invention discloses a pair of brake calipers with the gap adjustment function. The brake calipers are composed of a shell and an end cover. Two bearing pedestal clamping grooves are formed in the bottom end surface of the shell in parallel, and two guide grooves are also formed in the bottom end surface of the shell in parallel; bearing pedestals are embedded into the bearing pedestal clamping grooves, half-moon bearings are installed in the bearing pedestals in a sleeved mode, and transmission shafts are installed on the half-moon bearings in a sleeved mode; two guide sleeves corresponding to the guide grooves are arranged on the end cover, two piston sleeves are arranged between the two sleeves in parallel, and pistons are installed in the piston sleeves in a sleeved mode and are connected with a push rod through connecting plates; a spring, a bearing, an overload shaft and a pressure bearing are sequentially arranged between the two piston sleeves from outside to inside; a manual adjustment shaft which is composed of a threaded sleeve, a threaded rod and a shifting plate is installed in the guide sleeve on one side. The brake calipers solve the technical problems that the adjustment process of a traditional brake is complex and the traditional brake is very inconvenient to use; by the adoption of the shifting plate arranged outside the shell, gap adjustment efficiency can be effectively improved, and the gap adjustment process is easier, more convenient and faster to carry out.

Description

The brake callipers with gap adjustment function

Technical field

The present invention relates to a kind of brake callipers, particularly there is the brake callipers of gap adjustment function.

Background technique

Brake callipers is common in and utilizes on the traffic tool of disc brake system as brake, automobile for example, locomotive and bicycle etc., brake callipers of the prior art has two callipers bases, two linings, more than one piston and some fixed blocks, these fixed blocks are in order to mutually to lock these two callipers bases, when driver slams braking pedal or presses brake haft, by crossing hydraulic way, drive the piston promoting in this brake caliper, this piston promotes lining clamping braking disc, utilize friction mode to reach and make this brake rotor stop operating, and then tire is stopped operating.

Friction plate is after being used a period of time, continuous wearing and tearing due to friction plate, gap between friction plate and break is increased, in order to make break there is good braking ability, conventionally need to adjust the braking gap between friction plate and break, tradition adjustment mode is very complicated, is unfavorable for that operator carry out rapid adjustment.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art part, provide a kind of firm in structure, durable, the brake callipers that can adjust easily clamp and brake block gap easy to use

The object of the invention is to be achieved through the following technical solutions:

The brake callipers with gap adjustment function, housing and end cap, consist of, described housing bottom end face is shaped with two bearing support draw-in grooves and two guiding grooves side by side, in bearing support draw-in groove, is embedded with bearing support, in bearing support, be set with first quarter moon bearing, on first quarter moon bearing, be set with transmission shaft; On described end cap, be shaped with two pilot sleeves corresponding with guiding groove, be shaped with side by side two piston sleeves between two sleeves, in described piston sleeve, be set with piston, piston is connected with push rod by connecting plate, and is shaped with screw thread on push rod; Between described two-piston sleeve, be disposed with from the inside to the outside spring, bearing, overload axle and pressure bearing, and overload axle and pressure bearing are set in the overload shell on end cap; Described homophony fork runs through spring, connecting plate, is connected with bearing, overload axle and pressure bearing; The hand adjustment axle that in a described side pilot sleeve, suit is comprised of swivel nut, screw rod, plate, and this swivel nut and push rod engagement; Described hand adjustment axle runs through and connects housing, guiding groove and pilot sleeve, and hand adjustment axle plate is placed in outside; On described homophony fork, be set with homophony gear, and on push rod and homophony gear, screw thread is intermeshing.

Advantage of the present invention and economic effect are:

The present invention has overcome traditional brake and has adjusted complex procedures, uses very inconvenient technical barrier, is placed in the plate of outside by employing, can effectively improve gap regulated efficiency, makes gap adjust operation easier, quick.
