Description

Technical Field

[0001] The utility model relates to the technical field of automobile rollers, in particular to a braking roller for an automobile. Background Art

[0002] The brake system is a series of special devices on the car that allow the outside world to apply a certain force to certain parts of the car, thereby forcing it to brake to a certain extent. The general working principle of the brake system is to use the mutual friction between the non-rotating elements connected to the car body and the rotating elements connected to the wheels to prevent the rotation or rotation tendency of the wheels. The common brake system is divided into drum brake system and disc brake system. In the drum brake system, the brake roller plays an important role in the brake system.

[0003] During long-term use of the existing brake roller, the roller surface is subjected to multiple braking wear, which makes the roller diameter smaller, and then causes the braking action curve to change, which is prone to the phenomenon of poor return, and the driver is easily affected when performing braking operations.

[0006] As a preferred solution of the utility model, symmetrically arranged guide rods are fixedly connected inside the roller body, and both guide rods are slidably connected to the moving seat.

[0007] As a preferred solution of the utility model, the movable seat is located inside the roller body, and the movable seat is threadedly connected to the transmission screw.

[0008] As a preferred solution of the utility model, four push rods and four second round rods are provided, and the four push rods are rotatably connected to the second round rod.

[0009] As a preferred solution of the utility model, the rotating piece is slidably connected to the interior of the accommodating groove.

[0010] Compared with the prior art, the utility model has the beneficial effect of a brake roller for automobiles: when the surface of the roller is worn and becomes thinner as a whole, the compensation blocks can be contracted inwardly through the transmission of the transmission screw, so that the outer wall of the compensation block is flush with the outer wall of the roller, which can prevent the roller curve from changing and causing poor aftertaste, and has strong practicality.
