Description

Technical Field

[0001] The utility model relates to the technical field of wet brakes, in particular to a wet brake with adjustable braking force. Background Technique

[0002] The brake is an important part of a wheeled vehicle, and its function is to stop a moving vehicle. However, there are still certain defects in the existing wet brakes with adjustable braking force when in use. For example;

[0003] For example, a wet brake with adjustable clearance, with the publication number CN206958126U, includes a cylinder block and a piston arranged inside its cavity. It is characterized in that: a return spring and a bolt are arranged inside the piston cavity, the cylinder head is connected to the cylinder block through bolts, the outer steel sheet is in gear engagement with the cylinder head, a gasket is installed on the cylinder head, the inner friction sheet is in gear engagement with the hub, 3 adjusting rods are connected to the cylinder block through threads, and nuts, spring washers and seals are arranged on the adjusting rods. One or more adjusting mechanisms composed of the adjusting rods, nuts, spring washers and seals adjust the clearance between the outer steel sheet and the inner friction sheet, improving the problems of locking or brake failure caused by too small or too large clearance of the friction plates of the current wet brake, and also improving the problem of asynchronous braking of the left and right wheels caused by inconsistent clearances of the friction plates of the wet brakes on the left and right sides of the vehicle.

[0004] However, the wet brake with adjustable clearance still has the following disadvantages during actual use:

[0005] The gasket is driven to move by the return spring to perform the braking operation. During actual use, since it is difficult to precisely control the strength and preloading degree of the spring, the use of the return spring cannot meet the braking force requirements in different situations, making the overall braking force non-adjustable. Moreover, the return spring will wear after long-term use, reducing the overall safety. In addition, since the spring is inconvenient to precisely control for braking, redundant structures need to be added for auxiliary operation, increasing the overall installation cost and thus greatly increasing the overall maintenance cost.

[0006] In view of the above problems, it is urgent to innovate on the basis of the original wet brake with adjustable braking force. Therefore, we have proposed a wet brake with adjustable braking force that can well solve the above problems. Content of the Utility Model

[0007] The purpose of the present utility model is to provide a wet brake with adjustable braking force, so as to solve the problems proposed in the above background technology. Currently in the market, a gasket is driven to move by a return spring to perform the braking operation. In the actual use process, due to the fact that the strength and preloading degree of the spring are difficult to accurately control, the use of the return spring cannot meet the braking force requirements in different situations, resulting in non-adjustable overall braking force. Moreover, after long-term use, the return spring will wear, reducing the overall safety. In addition, when braking through spring reset, since the spring is not convenient for precise control, redundant structures need to be added for auxiliary operations, increasing the overall installation cost, and further greatly increasing the overall maintenance cost.
