DETAILED DESCRIPTION

[0017] The long-life parking integrated brake of the utility model is described below in combination with the drawings.

[0018] In the embodiment of the application, as shown in Figure 1 and Figure 2 The long-life parking integrated brake (hereinafter referred to as "the present application") comprises an oil filter 1, an oil filter rectangular tube body 1-1, a fence pole 1-2, a filter paper board 1-3, a filter paper board fixed edge board 1-4, a fixed plate 1-5, a brake shell 2, an oil cavity 3, a rotating shaft 4, a brake friction plate 5, a parking oil inlet hole 6, a driving piston 7, a parking piston 8, a disc spring 9 and a driving oil inlet hole 10. The rotating shaft 4 is installed in the brake shell 2 along the axis, the brake friction plate 5 is fixedly installed on the rotating shaft 4, the brake friction plate 5 is located in the oil cavity 3, the driving piston 7 for locking the brake friction plate 5 is arranged at the end of the brake shell 2, the parking piston 8 is arranged in the piston shell 11 outside the driving piston 7, the disc spring 9 is arranged outside the parking piston 8, the driving piston 7 and the parking piston 8 are respectively installed in the inner cavity of the piston shell 11, the parking oil inlet hole 6 and the driving oil inlet hole 10 are respectively arranged above the piston shell 11, the oil filter 1 is fixedly installed on the side of the oil cavity 3 close to the brake friction plate 5, the oil filter rectangular tube body 1-1 of the oil filter 1 penetrates through the front and back, the filter paper board 1-3 is installed on the inner side of the oil filter rectangular tube body 1-1, the filter paper board 1-3 occupies the entire cross section of the oil filter rectangular tube body 1-1 from low to high, the filter paper board fixed edge boards 1-4 are respectively fixedly installed on the two sides of the filter paper board 1-3, and the fence poles 1-2 are arranged on the front and back of the oil filter rectangular tube body 1-1.

[0019] The actuating mechanism of the parking integrated brake (hereinafter referred to as "the patent") with the utility model announcement No. CN203796816U, although the structure is simple, does not have the equipment for filtering the oil debris, and thus cannot solve the problem that the actual service life is far lower than the design requirement due to the too fast failure of the sealing ring during use. The present application can effectively filter the oil debris in the oil cavity 3 to delay the speed of the accumulation of the debris inside the equipment and improve the service life of the equipment.

[0020] The structure of the second embodiment is basically the same as that of the first embodiment, except that Figure 2 As shown, the oil filter paperboard 1-3 is wavy, with the crests and troughs aligned with the front and rear of the oil filter rectangular tube body 1-1. The wavy oil filter paperboard 1-3 can effectively increase the filtering area while better absorbing debris to prevent it from re-entering the oil.

[0021] To further optimize the performance of this application and increase the filtration area, the peak spacing of the oil filter paperboard 1-3 does not exceed three millimeters. To prevent surface contamination, the barrier bars 1-2 are made of stainless steel. For ease of assembly and disassembly, the oil filter rectangular tube body 1-1 is secured to the interior of the oil chamber 3 via fixed plates 1-5 mounted on both sides, with the front and rear openings parallel to the brake friction pads 5.

[0022] When the utility model is in use, the specific operations are as follows:

[0023] When using Figure 3 As shown, oil pressure enters the parking oil inlet 6, causing the parking piston 8 to return to contact the limiting end surface of the connector 12, compressing the disc spring 9, releasing the parking brake and allowing the vehicle to move. Oil pressure enters through the driving oil inlet 10, causing the driving piston 7 to move toward the brake friction pads 5, causing them to tighten and the rotation speed of the shaft 4 to slow to a stop, achieving the vehicle's driving brake.

[0024] The oil pressure in the parking oil inlet hole 6 is released, the pressing force of the disc spring 9 is released, pushing the parking piston 8, and the parking piston 8 pushes the driving piston 7 to move toward the brake friction plate 5, and the brake friction plate 5 is tightened to achieve parking braking.

[0025] When the vehicle is running, the brake friction plate 5 rotates at high speed following the rotating shaft 4, stirring the oil in the oil chamber 3 to generate flow. The flowing oil continuously passes through the oil filter paperboard 1-3 of the oil filter rectangular tube body 1-1, and the debris suspended in the oil can be filtered and collected by the oil filter paperboard 1-3.

[0026] In summary, the long-life integrated braking system of the present invention can effectively filter debris in the oil and slow down the accumulation of debris inside the equipment by setting an oil filter 1 in the oil chamber 3 to filter debris in the oil, thereby effectively preventing oil leakage and pressure relief and improving the service life of the equipment.
