Description

A height-adjustable disc brake caliper

technical field

The invention relates to the field of disc brake calipers, in particular to disc brake calipers with adjustable installation height.

Background technique

The caliper of the disc brake is equipped with two brake pads that can move towards each other. The two brake pads clamp the disc brake disc together to achieve braking. Influenced by problems such as uneven pad wear, it is difficult to achieve the ideal effect of two brake pads clamping the disc brake disc with the same force at the same time. It is often necessary to adjust the installation of the disc brake disc between the upper and lower brake pads after the disc brake pads are worn. height to ensure that the disc brake rotor is in the center of the upper and lower brake pads.

The traditional solution is generally to add or subtract gaskets in the mounting bolts to adjust the length of the threaded part of the mounting bolts so as to adjust the installation height between the disc brake disc and the mounting bolts to solve the problem of disc brake disc failure after the upper and lower brake pads are worn. The problem of being between the upper and lower brake pads and unable to provide an ideal braking state. Another way is to replace the new disc brake pads after the disc brake pads wear a little to ensure that the disc brake discs can be in the ideal center position of the upper and lower brake pads. , but this method is too expensive and not desirable, so it is necessary to adjust the length of the threaded portion of the mounting bolt.

However, even if the length of the threaded portion of the mounting bolt is adjusted by increasing or decreasing the gasket under the mounting bolt, there are still shortcomings: this adjustment generally requires professional maintenance personnel to perform, and users often cannot adjust it by themselves and even if professionals pass There will still be errors in the adjustment based on my own experience: First, the brake disc is not perfect, and its thickness will be uneven, and this unevenness will cause uneven wear of the brake pads. The wear on both sides is different, and the number of shims that need to be increased or decreased by the adjusting bolts on both sides is also uneven. Furthermore, since the thickness of the shims is fixed in a range, but when the wear of the brake pads is less than the thickness of the shims, It is impossible to add gaskets, and the only way to adapt to the wear is to manually polish the gaskets. Furthermore, since the thickness of each gasket is always in a fixed range, there is often a small range after adding gaskets. It cannot be adjusted through the gasket, so it is often necessary to manually polish the gasket, which is time-consuming and laborious, and can only be judged by the experience of the maintenance personnel to what extent the gasket needs to be polished, which will cause great harm to people, labor and resources. Big waste.

Furthermore, there are various disc brake calipers on the market, but the mounting holes of the calipers are of the same size, so it is necessary to design a universal adjustment device that can replace the shim and is easy and convenient.

Utility model content

The technical problem to be solved by the present invention is to address the above-mentioned deficiencies in the prior art,

A disc brake caliper with adjustable mounting height is available.

In order to achieve the above object, the present invention provides the following technical solution: a disc brake caliper with adjustable installation height, including two symmetrically arranged brake caliper bodies, and a brake caliper body is provided between the two brake caliper bodies that can be driven by an oil cylinder to face each other. Bonded or separated brake pads, brake gaps are provided between the brake pads, caliper mounting holes are provided on both sides of any one of the brake caliper bodies, and mounting bolts are provided on the caliper mounting holes. It is characterized in that: an adjustment device that can adjust the installation height of the installation bolt relative to the brake gap is provided between the caliper installation hole and the installation bolt, the adjustment device is provided with a connecting part, and the two ends of the connecting part are open outwards, so The end of the connection part away from the brake pad is provided with an adjustment part integrally formed with the connection part.

With the above technical solution, gaskets are provided between the caliper mounting holes on the main body of the traditional caliper and the mounting bolts, and at least one gasket is used to adjust the installation height of the brake disc relative to the mounting bolts. After wear and tear, it is necessary to increase or decrease the number of shims again to make the brake disc in the center of the two brake pads again, but this adjustment needs to be done by professionals, and there are still very slight errors, but theoretically this Errors are also not allowed, because it is difficult to provide a perfect braking state if there is an error, so it is difficult to make the brake disc in the center of the upper and lower brake pads in the traditional installation method, but the present invention establishes between the caliper installation hole and the installation bolt. An adjustment device, which can be adjusted perfectly only by clamping the upper and lower brake pads against the brake disc, so that non-professionals can also adjust through the adjustment device, which not only saves time and effort, but also is convenient to adjust.

With the above technical solution, the connecting portion that is threaded into the caliper mounting hole can be threaded in the caliper mounting hole to adjust its height relative to the axial direction of the caliper mounting hole, but this method is difficult to adjust manually or with a wrench. Therefore, an adjusting part integrally formed with the connecting part should be provided on the connecting part to facilitate adjustment.

The above-mentioned disc brake caliper with adjustable installation height can be further set as follows: the two ends of the adjustment part are opened, the inner diameter of the adjustment part is larger than the inner diameter of the connection part, and the connection between the adjustment part and the connection part forms a The cavity is connected with the mounting bolts in the cavity.

With the above technical solution, an adjustment part is provided to facilitate adjustment by a wrench or by hand, and a cavity is provided in the adjustment part and the connection part to place the mounting bolts into the cavity, which not only has a more beautiful appearance, but also has a more compact structure.

The aforementioned height-adjustable disc brake caliper may be further configured as follows: the surface of the connecting portion is provided with threads, and the connecting portion is connected to the mounting hole of the caliper through the threads.

By adopting the above technical solution, threads are provided on the surface of the connecting portion, and the thread is matched with the mounting hole of the caliper, so that the connecting portion can be rotated and adjusted in the mounting hole of the caliper through the thread.

The above-mentioned disc brake caliper with adjustable mounting height can be further configured such that: the length of the connecting portion is shorter than the screw length of the mounting bolt.

With the above technical solution, the length of the connecting portion is set to be shorter than the length of the threaded portion of the mounting bolt, which is in line with the actual use environment. If the length of the connecting portion is longer than the threaded portion of the mounting bolt, then the present invention will lose its practicability. Mounting bolts buried in the joint cannot perform a fixing function.

The above-mentioned disc brake caliper with adjustable installation height can be further configured as follows: the installation bolts are hexagon socket bolts.

With the above technical solution, since the mounting bolts are arranged in the inner cavity formed by the adjusting part and the connecting part, only hexagon socket head bolts can be used for fastening.

The aforementioned height-adjustable disc brake caliper can be further configured as follows: the adjustment part is an outer hexagon nut.

With the above technical solution, because the mounting bolts are hexagonal socket bolts, it is necessary to use external hexagonal nuts to facilitate the adjustment. The adjustment part can not only accommodate the mounting bolts but also can be tightened with a wrench, but it should be noted that the internal hexagonal bolts are used Setting the adjustment part as an external hexagon nut is only one of the easiest to process and most cost-effective implementations, and the present invention is not limited to this implementation.

The beneficial effects of the invention are: the installation height between the brake disc and the installation bolt is convenient to adjust, the adjustment device has strong versatility and can be popularized and used.
