Electric control and hydraulic integrated type multi-cylinder braking caliper

Abstract

The invention relates to an electric control and hydraulic integrated type multi-cylinder braking caliper. The electric control and hydraulic integrated type multi-cylinder braking caliper is characterized by comprising a braking caliper body, pistons, a thread sleeve, a screw, an internal braking block assembly, an external braking block assembly, a support, a guiding pin and a bolt. The electriccontrol and hydraulic integrated type multi-cylinder braking caliper belongs to a disc brake, can provide larger braking force, can be applied to a commercial vehicle, and is good in heat dissipationproperty and good in braking efficiency water stability and heat stability; the electric control and hydraulic integrated type multi-cylinder braking caliper has the traveling braking function and the parking braking function simultaneously, can be controlled through an electronic transmission device and a hydraulic transmission device, has the emergency braking function and is reliable and stable in working, compact in structure and easy to arrange; the parking function is electronically controlled so that braking force of the vehicle on different slopes can be automatically adjusted, and the automatic parking function can be achieved; and the adopted thread sleeve is of an integrated double-pressing-head structure, each braking block assembly is provided with two force bearing parts, thus the force bearing area is increased, force bearing is uniform, braking blocks are not liable to tilt, good contact of the braking blocks and a braking disc is ensured, abrasion is balanced, and thus the service life of a brake is prolonged.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to an electronically controlled hydraulic integrated multi-cylinder brake caliper. Background technique [0002] In the field of automobile braking technology, disc brakes are generally used in passenger cars, especially for the front wheels of cars. With the development of disc brake integrated parking technology, the rear wheels of cars have also begun to use disc brakes. Brakes, the existing integrated calipers have a single-cylinder structure, and the braking torque provided is small, so they can only be used for passenger cars or other vehicles below 3.5 tons, and cannot be used for vehicles with a full load of more than 3.5 tons, especially not for applications commercial vehicles. [0003] At present, commercial vehicles basically use drum brakes for service braking. The parking brake function can be realized by a device integrated on the drum brake or by a centra...

[0002] In the field of automobile braking technology, disc brakes are generally used in passenger cars, especially for the front wheels of cars. With the development of disc brake integrated parking technology, the rear wheels of cars have also begun to use disc brakes. Brakes, the existing integrated caliper is a single-cylinder structure, which provides a small braking torque and can only be used for passenger cars or other vehicles below 3.5 tons, and cannot be used for vehicles with a full load of more than 3.5 tons, especially not for applications commercial vehicle

[0003] At present, commercial vehicles basically use drum brakes for service braking. The parking brake function can be realized by a device integrated on the drum brake or by a central brake device installed on the drive shaft. After the drum brake is immersed in water, The performance drops seriously and recovers slowly, and the heat dissipation is poor, and the heat decay is serious, so it is difficult to realize the braking requirements of intelligent driving
