Description

Technical Field

[0001] This utility model relates to the field of wet brake technology, and more specifically, to a friction pad assembly for a wet brake. Background Technology

[0002] Wet brakes are braking systems that use lubricating oil or hydraulic oil for lubrication and cooling. They are widely used in vehicles, construction machinery, and other fields. Wet brakes place the brake friction pads in a closed environment and inject lubricating oil or hydraulic oil to form a lubricating film to reduce direct friction. Wet brakes typically consist of a brake disc / drum, friction pads, a lubrication system, and a control device. Wet brakes rely on lubricating oil or hydraulic oil for cooling and lubrication and are widely used in heavy vehicles, construction machinery, and mining equipment.

[0003] Traditional friction pads are prone to problems such as heat fade, uneven wear, and slow braking response due to insufficient heat dissipation under high-speed and high-pressure conditions, which affect braking performance and service life.

[0004] Therefore, there is an urgent need for a new type of friction pad structure to improve heat dissipation performance and enhance braking stability and reliability. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes a friction pad assembly for a wet brake to overcome the above-mentioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] A friction pad assembly for a wet brake includes a disc body, a positioning port on the inner side of the edge of the disc body, a spline at the center of the disc body, spiral grooves on the inner sides of the upper and lower ends of the disc body, radial grooves between the spiral grooves, and a through hole on the inner side of the disc body.

[0008] As a further embodiment of this utility model, the positioning port is a semi-circular groove, and the positioning ports are arranged at equal intervals around the circumference.

[0009] As a further embodiment of this utility model, the spiral grooves are arranged symmetrically in the upper and lower parts.

[0010] As a further embodiment of this utility model, the radial grooves are arranged symmetrically from top to bottom and are circumferentially arranged.

[0011] As a further embodiment of this utility model, the through holes are provided in two sets, inner and outer, and the through holes are arranged at equal intervals around the circumference.

[0012] As a further embodiment of this utility model, the spline is an internal spline structure, used to cooperate with the drive shaft to transmit torque.

[0013] As a further embodiment of this utility model, the disc body is composed of a metal substrate and a friction material layer, and the through hole penetrates the friction material layer.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention utilizes spiral grooves and radial grooves to form a fluid channel, promoting oil flow, quickly removing heat and wear debris, and preventing localized overheating. The through-hole design increases the heat dissipation area, further improving cooling efficiency and maintaining stable braking performance. The positioning port is a semi-circular groove evenly distributed around the circumference, facilitating assembly and positioning while reducing vibration and noise caused by installation errors. The symmetrically arranged grooves ensure uniform force distribution during double-sided braking, extending service life. Attached Figure Description
