Problems solved by technology
 Such as figure 1 , 2 3, the wet multi-disc parking brake of the present invention includes a brake cover 1, a brake housing 2, a piston 3, a friction pair 4, a spring 5, a spline shaft 6 and a seal 7.
 The brake cover 1 and the brake housing 2 are fixedly connected to form a brake box. The piston cylinder enclosed by the brake cover 1 and the brake housing 2 is equipped with a piston 3 that can move left and right.
 The piston cylinder includes a first cylinder hole 11 with a larger diameter and a second cylinder hole 12 with a smaller diameter. The piston 3 has a first sliding surface 3-1 with a larger diameter and a second sliding surface with a smaller diameter. 3-2, the first sliding surface 3-1 of the piston 3 slidingly fits with the hole wall of the first cylinder hole 11, and the second sliding surface 3-2 sliding fits with the hole wall of the second cylinder hole 12,
 The brake cover 1 has a plurality of spring mounting holes 1-1, and springs ...
