A screw thread bidirectionally driven disc brake piston resetting tool has a main body, a first clamping plate and a second clamping plate, wherein both sides of the main body are adjacent to the first clamping plate and the second clamping plate respectively. A driving piece and a tubular revolving part are pivoted in the main body. The driving piece drives the revolving part to revolve. The revolving part is screwed on a first connecting piece and a second connecting piece respectively. The first connecting piece and the second connecting piece are linked with the first clamping plate and the second clamping plate respectively, shifting oppositely. The distance between the first clamping plate and the second clamping plate can be increased without increasing the thickness of the main body, and it is applicable to piston resetting push-back operation for disc brakes of different sizes.

A restriction device includes a bridge including a connection portion and a locking portion respective formed on two ends thereof. The connection portion includes a protrusion on the outside of the bridge. The protrusion is to be connected to one of the connection parts on the hub. The locking portion includes a tubular part on the inside of the bridge. The tubular part is located beyond the outer periphery of the hub. A space is formed between the inside of the bridge and the tubular part so as to accommodate the hub on the disk body when the protrusion is connected to one of the connection parts on the hub. The tubular part contacts one of two ends of the brake caliper to restrict rotation of brake disk.

A piston resetting tool for a disk brake includes a main body, a first pressing plate, a second pressing plate and an operating rod. The side of the main body is connected to the first pressing plate, the second pressing plate is adjacent to the other side of the main body, and the operating rod is configured on one end of the main body. The inside of the main body is pivotally configured with a rotating piece and the rotating piece is configured with a middle tube through a first screw barrel in threaded joint. The middle tube is configured with a screw rod through a second screw barrel in threaded joint and the screw rod is connected to the second pressing plate, so that the second pressing plate can move to and fro.

In order for hydraulic disk brakes to function properly over time, associated brake pads are changed periodically. In order to exchange old brake pads for replacement brake pads, a disk brake may require pushing back the brake pistons within a brake caliper body in order to make room for installation of replacement pads. Current tools and methods typically require removal of a wheel from a vehicle, removal of a brake rotor from the wheel, and/or removal of the brake caliper body from a rotor. The presently disclosed caliper piston tool allows brake pads to be replaced without dismantling various components of the vehicle, resulting in significant time and cost savings as well as convenience for do-it-yourself and professional mechanics alike.

The present disclosure relates to a disc brake having an electromechanical actuator for vehicles, in particular for utility vehicles, comprising a brake disc, a brake carrier and a brake caliper of a vehicle for applying the brake disc by means of brake linings. Current tests have shown that the tappet after assembly is not fixed correctly in a housing of the electromechanical actuator. The tappet may after positioning fall out of the rotary lever, which results in the force transmission for applying the brake disc being interrupted and the brake disc not being able to be applied. An object of the present disclosure is to overcome the problems from the prior art and to provide a disc brake with an electromechanical actuator which reduces or even prevents damage to the tappet, the cam disc and the housing of the electromechanical actuator.

The invention relates to a system and to a method for coating workpieces using a coating device, which is designed to apply a metal coating to a surface of the workpiece. According to the invention, it is provided that a plurality of coating devices, which are designed as identical coating modules, are provided and are arranged in a module group, that an input measuring station is assigned to the module group, by means of which station a surface of the face of the workpiece to be coated can be detected, that a conveying apparatus is provided, by means of which a workpiece can be supplied to one of the coating modules from the input measuring station, and that an output measuring station is assigned to the module group, by means of which station a surface of the coated face of the workpiece can be detected.

The invention relates to a coating device and to a method for metal-coating of workpieces, comprising a housing, which surrounds a working space, a retaining apparatus for retaining at least one workpiece in the working space, at least one deposition apparatus comprising a deposition nozzle for applying a metal powder to the workpiece surface to be coated, and a laser for locally melting the metal powder on the workpiece surface to form a coating, and at least one movement apparatus, by means of which the at least one deposition apparatus can be moved relative to the workpiece surface during the coating. Particularly efficient coating is made possible by at least two deposition apparatuses being arranged in the working space in the housing, which apparatuses are designed to simultaneously apply and melt metal powder.

Disclosed herein is an expandable device adapted to forcibly separate spaced components having generally parallel opposed surfaces defining a cavity therebetween, the expandable device having a jaw assembly with a pair of opposing jaws and actuating means for opening the jaws, the actuating means including a separating member configured to be driven between the jaws so as to push apart the jaws such that the jaws are openable between a contracted configuration where the jaws are receivable in the cavity to an expanded configuration where the jaws are forced apart by the actuating means such that the outwardly directed surfaces of the jaws are engageable with the opposed surfaces and exert oppositely directed forces thereon. Also disclosed herein is an apparatus configured to carry at least one said expandable device, and an assembly comprising two said apparatus.

A hydraulic piston resetting tool for a disk brake includes a main body, a first pressing plate, a second pressing plate and a holding pole, wherein, one side of the main body is connected to the first pressing plate, the second pressing plate is adjacent to the other side of the main body, and the holding pole is connected to the front end of the main body. The inside of the main body is pivotally configured with a first cylinder barrel, the inside of the first cylinder barrel is pivotally configured with a second cylinder barrel, and the inside of the second cylinder barrel is pivotally configured with a stopping piece. The stopping piece is connected to the second pressing plate. The stopping piece activates the reciprocating displacement of the second pressing plate.

A brake assembly and a method of assembling a brake assembly. The brake assembly may have an actuator mount that may have a tapered mounting hole. A mounting feature of a brake actuator may be insertable into the mounting hole at an oblique angle with respect to a mounting hole axis.
