Embodiment Construction

[0026] The present invention will be described in detail below in conjunction with embodiments, but the scope of implementation of the present invention is not limited to the following embodiments.

[0027] Such as Figure 1-Figure 3 As shown, a service and parking brake integrated hydraulic caliper disc brake includes a single-acting parking brake hydraulic cylinder 10 and a dry caliper disc brake. The piston 2 of the single-acting parking brake hydraulic cylinder 10 is connected The brake piston 11 of the dry caliper disc brake is provided with a driving position switch 6 on the single-acting parking brake hydraulic cylinder 10, and the piston 2 retracts and touches the driving position switch 6 to be turned on.

[0028] An oil chamber is provided on one side of the piston 2 and a strong brake spring 3 is provided on the other side. When parking brake, piston 2 presses brake spring 3 to press brake piston 7 to achieve braking; when driving, piston 2 drives brake piston 7 to retr...

Abstract

The invention discloses a driving and parking brake integrated type hydraulic clamp disc brake. The driving and parking brake integrated type hydraulic clamp disc brake comprises a single-action parking brake hydraulic oil cylinder and a dry type clamp disc brake. A piston of the single-action parking brake hydraulic oil cylinder is connected with a brake piston of the dry type clamp disc brake, a driving position switch is arranged on the single-action parking brake hydraulic oil cylinder, and the piston retracts to touch the driving position switch to be switched on. Compared with the prior art, the brake has the beneficial effects that the device is easy and convenient to use and low in use cost; the brake is adopted for ensuring safety and high efficiency of a parking system while an existing driving brake property is not affected, and meanwhile, the system can serve as an emergency brake when an engineering machine is in power failure; the requirement for a user is low, and the user can use the brake through simple training; and a part of existing brake clamp is modified to meet the use needs of an old device.

Description

Technical field [0001] The invention relates to the field of engineering machinery brakes, in particular to a hydraulic caliper disc brake integrated with service and parking brakes. Background technique [0002] In the dry caliper disc brake system of construction machinery, driving and parking are two separate systems arranged and installed separately. In actual use, damage to the parking system caused by forgetting to release the parking brake is very common, and many are broken and not repaired. Causes great hidden dangers to mechanical safety and personal safety. [0003] Therefore, there is a need for a caliper brake system that is simple and convenient in layout and can combine the two together. Avoid damage to the parking system, improve braking efficiency, and solve potential safety hazards. Summary of the invention [0004] The purpose of the present invention is to provide a hydraulic caliper disc brake integrated with service and parking brakes, which has simple struc...
