Abstract
The utility model relates to a disc brake piston, which is characterized in that the piston is directly and integrally stamped into a bottle shape by sheet material, the bottom of the piston forms a concave spherical surface shape, and a piston opening on the top is contracted. The piston has the advantages that the piston wall is thinner; material consumption, energy consumption and working hours are low; machining without cutting can be realized; the hydraulic distribution is uniform; the rigidity is strong.
Description
The utility model relates to a kind of brake plunger.
Existing large-scale industrial and mineral, the most of hydraulic brake that adopts of haulage vehicle, wherein piston is a general part, requirement is big.Up to now, generally all adopt solid bar or forging to become flat straight barrel structure through Vehicle Processing, its shortcoming mainly is that piston wall thickness is big, and material consumption, energy consumption, man-hour are consumed big.
The purpose of this utility model is to provide a kind of wall thin, and material consumption, energy consumption, man-hour are consumed little, and hydraulic pressure is evenly distributed, the disk type braker piston of good rigidly.
The disk type braker piston is ampuliform by the direct whole punching press of sheet material, and the bottom is recessed sphere shape, the reducing of top piston mouth.
The utility model and existing disk type braker piston compare, owing to adopt the direct whole punching press of sheet material, so piston wall is thinner, material can be saved more than 50%, and energy consumption is little, man-hour is short, realizes no cutting.Because piston base is recessed sphere, so the hydraulic pressure of piston is evenly distributed.Because the top reducing of piston mouth, so the rigidity of piston strengthens greatly.
Fig. 1 is a sectional drawing of the present utility model.
As shown in Figure 1, disk type braker piston 1 strikes out ampuliform by the direct integral body of sheet material, and bottom 2 is recessed sphere shape, 3 reducings of top piston mouth.
