Abstract
The invention relates to the technical field of brakes on automobiles, in particular to a ratchet claw in an automatic ratchet regulator in a brake, wherein the ratchet claw is provided with a mounting hole (1), one end face of the ratchet claw is provided with sector teeth (2), and the other end of the ratchet claw is provided with an opening (3). The ratchet pawl in the automatic ratchet regulator can ensure that the sector-shaped rack matched with the ratchet pawl can only rotate towards one direction and can not rotate towards the opposite direction, and the spring hook can ensure that the sector-shaped teeth of the ratchet pawl always form slight pressure on the sector-shaped rack matched with the sector-shaped rack, thereby improving the working reliability of the brake.
Description
Technical Field
The invention relates to the technical field of brakes on automobiles, in particular to a ratchet claw in an automatic ratchet regulator in a brake.
Background
Numerous challenges exist in the design of annular disc brakes. One is to be able to generate a suitable clamping force using an actuator that fits within the space available for the brake. Annular disc brakes are often provided in vehicles, and these are usually mounted within or very close to a respective wheel of the vehicle. Even in the case of large vehicles, the space available for each brake is relatively limited. In addition, vehicle manufacturers are continually seeking increasingly compact brakes to reduce this space. There is always room for improvement in the design of annular disc brakes when it is desired to design an annular disc brake that requires connection to a source of primary power using a pneumatic system as the brake.
Disclosure of Invention
In order to solve the above problems, the present invention is directed to provide a ratchet pawl in an automatic ratchet adjuster of a brake, which can make the structure of the brake more compact and the braking performance more reliable.
In order to achieve the purpose, the invention adopts the following technical scheme:
a ratchet claw for an automobile brake is provided with a mounting hole, fan-shaped teeth are arranged on the end face of one end of the ratchet claw, and an opening is formed in the other end of the ratchet claw.
Further, the fan-shaped teeth are composed of a plurality of teeth.
Furthermore, one side of the opening is provided with a groove.
The ratchet pawl in the automatic ratchet regulator can ensure that the sector-shaped rack matched with the ratchet pawl can only rotate towards one direction and can not rotate towards the opposite direction, and the spring hook can ensure that the sector-shaped teeth of the ratchet pawl always form slight pressure on the sector-shaped rack matched with the sector-shaped rack, thereby improving the working reliability of the brake.
Drawings
FIG. 1 is a schematic structural view of the present invention;
in the figure: 1. mounting holes; 2. a fan-shaped tooth; 3. opening a hole; 4. a groove.
Detailed Description
The following detailed description of the embodiments of the present invention is provided to enable those skilled in the art to more clearly understand the embodiments of the present invention, and the present invention is not limited by the embodiments and the accompanying drawings.
As shown in figure 1, the ratchet pawl for the automobile brake is provided with a mounting hole 1, fan-shaped teeth 2 are arranged on one end face of the ratchet pawl, and an opening hole 3 is arranged at the other end of the ratchet pawl.
Preferably, said sector-shaped teeth 2 consist of a plurality of teeth.
Preferably, the opening 3 is slotted on one side with a slot 4.
The ratchet pawl is rotatably connected with the rotating shaft through a mounting hole 1, and sector teeth 2 on the end face of one end of the ratchet pawl are meshed with a sector rack matched with the automatic ratchet regulator; the other end of the ratchet pawl is provided with an opening 3, so that a tension spring is convenient to install, and one side of the opening 3 is provided with a groove 4 to form a spring hook, so that the tension spring is more convenient to install; under the action of the tension force of the tension spring, the sector gear 2 always forms slight pressure on the sector gear rack meshed with the sector gear rack, so that the sector gear rack can only rotate towards one direction and cannot rotate towards the opposite direction.
The embodiments of the present invention are described in detail above with reference to the drawings, but the present invention is not limited to the described embodiments. It will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, which is still within the scope of the invention.
Claims (3)
1. A ratchet claw for an automobile brake is provided with a mounting hole (1) and is characterized in that fan-shaped teeth (2) are arranged on the end face of one end of the ratchet claw, and an opening (3) is formed in the other end of the ratchet claw.
2. A ratchet pawl for use in automotive brakes according to claim 1, characterized in that the sector-shaped teeth (2) consist of a plurality of teeth.
