Description

Technical Field

[0001] The utility model relates to the field of brake motors, in particular to a brake motor matched with a gear. Background Art

[0002] The brake motor is an integral part of the braking system, serving several key functions: 1. Safety: The brake motor ensures the vehicle can stop quickly in an emergency. Its crucial role in the braking system lies in its ability to rapidly convert hydraulic energy into mechanical energy, effectively braking the vehicle. 2. Reliability: Driven by hydraulic oil, the brake motor is a traditional braking system with excellent braking performance and widespread application.

[0003] The motor counterbalance valve is a common hydraulic control component, primarily used to control oil flow and pressure in hydraulic systems. During hydraulic motor operation, if the load torque generated by the hydraulic motor exceeds the torque range of the gear motor due to load weight or load changes, the motor may stall or coast, shortening the motor's service life and reducing equipment reliability. The hydraulic motor counterbalance valve protects the hydraulic motor by limiting oil flow and pressure in the hydraulic system, preventing stalling or coasting, thereby improving the reliability and service life of the hydraulic system.

[0004] However, existing brake motors with hydraulic motor balancing valves often have problems such as low efficiency and short service life. It is necessary to further develop a new brake motor structure to overcome the problems of the prior art. Utility Model Content

[0005] Purpose of the utility model: In view of the shortcomings and defects of the existing technology, the utility model provides a brake motor that cooperates with gears, integrating the motor, brake and two-way balancing valve into one, and adjusting the oil flow and pressure of the brake motor through the two-way balancing valve to achieve richer functions and control, improve work efficiency and extend service life.

[0006] Technical solution: The utility model is a brake motor that cooperates with gears, which is characterized by comprising a brake, a rotor-stator pair and a two-way balancing valve connected in sequence, and the oil inlet oil circuit is controlled by the brake, the rotor-stator pair and the two-way balancing valve; the brake, the rotor-stator pair and the two-way balancing valve are provided with a two-way balancing valve hole, a rear housing oil hole and a rotor-stator pair oil hole for the passage of hydraulic oil in sequence.

[0007] Wherein, the brake is provided with a brake shaft, and the brake shaft is connected to the first bearing and the second bearing.

[0008] The brake is provided with a shaft sealing ring, a brake pad lining, a steel pressure plate, a sealing ring, a piston and a spring; the sealing structure of the brake includes a rotating ring and a stationary ring.

[0009] Among them, the bearing 1 adopts bearing 6214, and the bearing 2 adopts bearing 6210.

[0010] Wherein, the brake is connected with the lifting eye screw.

[0011] Wherein, the eye screw is an M10×16 screw.

[0012] Wherein, the two-way balancing valve is provided with a valve block, and the valve block is connected to the brake through a connecting plate.

[0013] Beneficial effects: Compared with the prior art, the utility model has the following significant advantages: The utility model provides a brake motor with a two-way balancing valve and a gear, wherein the output shaft extension is a large-diameter gear. This brake motor consists of three parts: a braking part, a motor part, and a two-way balancing valve. It can provide transmission and braking forces for large aerial work vehicles and large agricultural machinery. The motor input flow and pressure are controlled by the balancing valve, and the direct engagement of the gears and the machine reduces energy loss and improves the mechanical efficiency of the machine.

DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The brake motor of the present invention cooperates with the gear, comprises a brake 1, a rotor-stator pair 2 and a two-way balancing valve 3 connected in sequence, and the oil inlet oil circuit is controlled by the brake 1, the rotor-stator pair 2 and the two-way balancing valve 3; the brake 1, the rotor-stator pair 2 and the two-way balancing valve 3 are provided with a two-way balancing valve hole 16, a rear housing oil hole 17 and a rotor-stator pair oil hole 18 for the passage of hydraulic oil in sequence.

[0024] The brake 1 of the present invention is provided with a brake shaft 4, which is connected to bearing 1 6 and bearing 2 12. The brake 1 is provided with a shaft sealing ring 5, a brake pad 7, a steel pressure plate 8, a sealing ring 9, a piston 10 and a spring 11; the sealing structure of the brake 1 includes a rotating ring and a stationary ring. Bearing 1 6 adopts bearing 6214, and bearing 2 12 adopts bearing 6210. The brake 1 is connected to a lifting screw 13. The lifting screw 13 is an M10×16 screw. The two-way balancing valve 3 is provided with a valve block (15), and the valve block 15 is connected to the brake 1 through a connecting plate 14.

[0025] The utility model enables the sliding end faces of the rotating ring and the stationary ring to remain in contact under the action of fluid pressure and spring 11 to achieve a sealing effect. Mechanical friction between the end faces of the rotating ring and the stationary ring will cause wear. Under the action of spring 11 and pressure oil, the rotating ring always fits the end face of the stationary ring. This design avoids the shortcomings of conventional sealing components. The sealing structure can compensate for axial wear in a timely manner and can keep the axial sealing surface in contact at all times. The requirements of the hydraulic motor for low friction coefficient and impact resistance are met. Because of the good self-lubrication, it is guaranteed that the motor has a higher volumetric efficiency and total efficiency at high pressure, extending its service life.

[0026] This utility model controls the oil inlet circuit through the brake 1, the rotor-stator pair 2, and the two-way balancing valve 3. This allows the balancing valve to be adjusted to control the oil flow and pressure in the hydraulic system. A portion of the hydraulic oil flows through the two-way balancing valve hole 16, into the rear housing oil hole 17, and then through the rotor-stator pair oil hole 18. Finally, the hydraulic oil enters the brake housing, reaching the brake's opening pressure, allowing the motor to rotate normally.
