Auto Brake Caliper Guide
In the automobile braking system, the brake caliper is a vital component, which is responsible for pressing the brake pads against the brake disc, thereby generating friction to slow down or stop the vehicle.
According to the different designs and working principles, automobile brake calipers can be mainly divided into two categories: fixed calipers (also called single-piston or multi-piston fixed calipers) and floating calipers (also called floating calipers or sliding calipers).
Fixed Brake Caliper
Structure:
The design feature of the fixed caliper is that its position is fixed and will not move during the braking process. It usually consists of two main parts: the brake pad and the caliper body. The brake pad is installed on the inner side of the caliper body and generates friction with the brake disc through the push of the piston.
The basic structure of the fixed caliper usually includes a fixed caliper body, and the brake pad is arranged inside the caliper body. These brake pads generate friction with the brake disc through the push of the piston. The piston is usually controlled by a hydraulic system. When the driver steps on the brake pedal, the hydraulic system pushes the piston forward, so that the brake pad is in close contact with the brake disc and generates braking force. The advantage of the fixed caliper is that it has a higher stability and uniformity of braking force, because the brake pad always remains in a fixed position during the braking process.
Working Principle:
When the brake system is activated, the piston pushes the brake pad in the caliper body to make it close to the brake disc. Through friction, the brake disc is slowed down or stopped rotating, thus achieving the braking effect.
Advantages and Characteristics:
Good stability: Since the position of the fixed caliper is fixed, it can provide stable braking force during braking to ensure the consistency of the braking effect.
High precision: The fixed caliper can ensure high precision during the design and manufacturing process, thereby ensuring the correct position of the brake pad and good contact with the brake disc.
Precise repeatable positioning: The fixed caliper has the characteristics of fast clamping and releasing the workpiece, and can ensure that the workpiece processed each time is in the same position and direction, thereby improving the accuracy of repeatability.
Floating Brake Caliper
Structure:
The design of the floating caliper allows it to float within a certain range. It usually includes one or more floating mechanisms, so that the caliper can adapt to objects of different shapes and sizes.
The structure of the floating caliper is relatively complex. It mainly consists of a caliper body, a floating mechanism and a brake pad. The floating mechanism allows the caliper body to move relative to the bracket to a certain extent during the braking process. This design enables the floating caliper to adapt to brake discs of different shapes and sizes and improve the braking effect. When braking, the inner piston and brake pad first contact the brake disc. As the braking force increases, the caliper body will float along the guide pin, so that the outer brake pad will gradually contact the brake disc to achieve uniform braking. The advantage of the floating caliper is that it is highly adaptable and can cope with various complex braking scenarios, but its braking force uniformity may not be as good as that of the fixed caliper.
Working Principle:
When the brake system is activated, the floating caliper will fine-tune according to the position and shape of the brake disc to ensure that the brake pad can be evenly applied to the brake disc. This adaptive ability of the floating caliper enables it to provide stable braking force under different working conditions.
Advantages and Characteristics:
Strong adaptability: The floating caliper can adapt to objects of different shapes and sizes, so it has a wide range of applicability.
Reduce damage: Since the clamping force of the floating caliper can be adjusted, the clamping force can be adjusted according to the characteristics of the object to avoid damage to the object.
Improve work efficiency: The design of the floating caliper makes the clamping process more flexible and can adapt to a variety of work scenarios, thereby improving work efficiency.
