Description

Technical Field

[0001] The invention relates to the field of mechanical braking, in particular to an underwater electric hydraulic disc brake with adjustable braking torque. Background Art

[0002] At present, electric hydraulic disc brakes on the market are used on land, and there are no products for underwater use. When the products are used underwater, the following technical problems need to be solved: how to ensure the protection level of the thruster when it is deep in water; when the brake is placed underwater, the torque is difficult to adjust; solve the anti-corrosion problem of the brake spring in water. Summary of the invention

[0003] The purpose of the present invention is to provide an underwater electric hydraulic disc brake with adjustable braking torque to solve the problems raised in the background technology.

[0004] The underwater electric hydraulic disc brake with adjustable braking torque of the present invention comprises a base, a built-in spring pusher, a brake arm A, a triangular plate, a pull rod, a brake arm B, and a brake pad. The brake pads are symmetrically installed on the end faces opposite to the brake arm A and the brake arm B. The bottom ends of the brake arm A and the brake arm B are fixed to the base with a pin shaft. The invention is characterized in that the upper end of the brake arm B and one end of the pull rod are fixed to the same end angle of the triangular plate, the brake arm B is connected to the triangular plate through a pin shaft, and the upper end of the brake arm A is connected to the other end of the pull rod through a pin shaft; the other end angle of the triangular plate is connected to the joint pin shaft of the built-in spring pusher, and the bottom end of the built-in spring pusher is fixed to the base;

[0005] The built-in spring pusher includes a shell, a motor assembly, a piston, a piston rod, blades, and a spring. The motor assembly, piston, and spring are all sealed in the shell. The watertight joint is installed on the shell through a thread and is electrically connected to the motor assembly. The blade is connected to the motor output shaft with a flat key. The spring is sleeved on the piston rod and pre-compressed and placed between the top surface of the piston and the end surface of the pusher shell. The movable end of the piston rod is located outside the shell and is fixedly connected to the joint.

[0006] The working principle of the underwater electric hydraulic disc brake with adjustable braking torque of the present invention is that when the power is turned on, the current is transmitted to the motor assembly through the watertight joint, the motor rotates, and drives the blades to generate oil pressure in the cavity. The oil pressure pushes the piston and the piston rod to overcome the spring force formed by the spring and move to the rated stroke and maintain this position. The spring force generated by the pre-compressed built-in spring (the spring is built-in to solve the problem of corrosion prevention in water) is transmitted to the brake pad through the triangle plate, two brake arms and the pull rod. The brake pad and the brake disc generate a clamping force to achieve braking. When the torque needs to be adjusted, by changing the frequency of the pusher power supply and controlling the blade speed, the blade stirs the oil in the cavity, and the piston generates a certain thrust to offset the compression force of the built-in spring, thereby changing the braking torque of the brake, so that the braking torque of the brake can be intelligently adjusted within the rated torque range.

[0007] The underwater electric hydraulic disc brake with adjustable braking torque of the present invention is an electric hydraulic disc brake for deep water. The spring is built in, each sealing end face adopts a sealing structure, the piston rod adopts a double sealing structure, and the power outlet adopts a special underwater watertight plug, which improves the protection level of the pusher and protects the spring from water corrosion, meeting the use of the pusher in a deep water environment. And by changing the power frequency, increasing or decreasing the thrust of the pusher, and changing the spring force, the brake torque can be intelligently adjusted within the rated torque range.
