Description

Tool for removing and installing disc brake caliper spring

The present invention relates to auto repair tools, in particular to a tool for removing and installing disc brake caliper springs.

Press, in the disc brake device, for the purpose of fixing the disc, it is elastically clamped on the caliper member of the disc brake device through a spring member with an appropriate shape to provide support and positioning for the adjacent disc brake The effect, but because different calipers often have big differences in shape, structure and size, the spring used to provide positioning effect to the pad has a shape and size with the attached caliper. The difference makes it difficult to have standards.

As far as the warranty personnel are concerned, when they are disassembling and installing the fixed spring of the piece, since there is no suitable tool for their use in the prior art, they can only use other tools such as a screwdriver to apply force. Pull the spring away from the caliper by using the tool, or directly by hand, which may cause the risk of injury to the body of the maintenance personnel, and need to be avoided.

Therefore, the main purpose of the present invention is to provide a tool for removing and installing the spring of the disc brake caliper, which can facilitate the user to remove and install the spring that is elastically clamped on the caliper for fixing the plate. Of homework.

The reason is that, in order to achieve the above object, the tool provided by the present invention for removing and installing the disc brake caliper spring has a technically important feature that the tool includes a tool for connecting with different parts of the disc brake caliper spring. Support portion and a second support portion, and use a third support portion to change the distance between the first support portion and the third support portion, and/or the distance between the second support portion and the third support portion to change According to the shape of the disc brake caliper spring connected to it, the disc brake caliper spring can be removed from the connected disc brake caliper or assembled to the disc brake caliper to facilitate the implementation of the work by the warranty personnel .

Furthermore, the tool not only includes the first support portion, the second support portion, and the third support portion, but also includes a body provided as other components and a body for driving the third support portion A driving part that moves between a first position and a second position.

The first support portion is provided on the body and used to connect with the disc brake caliper spring, and the second support portion is provided on the body separately from the first support portion and used to connect with the The disc brake caliper spring is connected, and the third support part is also provided on the body and used to connect with the disc brake caliper spring, and is separated from the first support part by a first distance and separated from the second support part A second distance, the driving part is arranged on the body, and used to drive the third support part to move between the first position and the second position to change the first distance and/or the second distance The length.

The relative spatial positions of the first support portion, the second support portion and the third support portion are adapted to connect with different parts of the disc brake caliper spring and can apply force to the disc brake caliper spring to change the disc The shape of the brake caliper spring is better, and the better one is that the third supporting portion can be interposed between the first supporting portion and the second supporting portion.

The driving part is used to drive the third support part to move the force application type, which can cause the third support part to move between the first position and the second position, for example, can be rotated by a screw A transmission method that changes motion to linear motion, or other known drive technology that can achieve this effect.

Wherein, when the movement of the third support portion between the first position and the second position is a linear reciprocating motion, in order to ensure the stable displacement of the third support portion, the third support portion and the The body is a combination of sliding joints.

In order to make the tool available for maintenance personnel to use disc brake caliper springs of different sizes, the first support part and/or the second support part can be individually combined with the body, and the combination structure allows The displacement along with the deformation of the disc brake caliper spring is, for example, a pivotal joint structure that allows the first support portion and/or the second support portion to deflect.
