Short problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of brake cylinder of band automatic adjustment, packet
Wheel cylinder cylinder body is included, the inner cavity of the wheel cylinder cylinder body is symmetrically plugged with wheelcylinder piston, and the outer wall of the wheelcylinder piston is socketed with sealing
Leather cup, and the outer wall of sealing cup and the inner wall of wheel cylinder cylinder body come into full contact with, the inner end outer wall socket of the wheelcylinder piston is limited
Position ring, and the inner wall of the outer wall of stop collar and wheel cylinder cylinder body is interference fitted, the left and right ends of the wheel cylinder cylinder body are provided with anti-
Dust hood, the outer end of the wheelcylinder piston run through dust cover, are plugged with bleed screw, the wheel cylinder cylinder at the top of the wheel cylinder cylinder body
Oil transportation mouth is plugged at the top of body, and oil transportation mouth is located at the rear side of bleed screw, bottom and the wheel cylinder cylinder body of the oil transportation mouth
Inner cavity top connection.
Preferably, by connecting and fixing between the wheel cylinder cylinder body and dust cover.
It preferably, is to be threadedly coupled between the wheel cylinder cylinder body and bleed screw.
Preferably, the stop collar is spring steel construction stop collar.
Compared with prior art, the utility model has the beneficial effects that the wheel cylinder of this kind of structure, because of stop collar
Structure setting can automatically adjust the initial position of wheel cylinder, can increase the service life of brake block, practical.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
In figure: 1 wheel cylinder cylinder body, 2 sealing cups, 3 stop collars, 4 wheelcylinder pistons, 5 dust covers, 6 bleed screws.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Referring to Fig. 1, the utility model provides a kind of technical solution: a kind of brake cylinder of band automatic adjustment, including point
Pump cylinder 1, the inner cavity of the wheel cylinder cylinder body 1 are symmetrically plugged with wheelcylinder piston 4, and the outer wall of the wheelcylinder piston 4 is socketed with sealing
Leather cup 2, and the outer wall of sealing cup 2 and the inner wall of wheel cylinder cylinder body 1 come into full contact with, the inner end outer wall socket of the wheelcylinder piston 4
Restraining position ring block 3, and the inner wall of the outer wall of stop collar 3 and wheel cylinder cylinder body 1 is interference fitted, the left and right ends of the wheel cylinder cylinder body 1 are equal
It is provided with dust cover 5, dust cover 5 is run through in the outer end of the wheelcylinder piston 4, and the top of the wheel cylinder cylinder body 1 is plugged with deflation spiral shell
Nail 6, the top of the wheel cylinder cylinder body 1 is plugged with oil transportation mouth, and oil transportation mouth is located at the rear side of bleed screw 6, the oil transportation mouth
Bottom is connected to the inner cavity top of wheel cylinder cylinder body 1.
Wherein, by connecting and fixing between the wheel cylinder cylinder body 1 and dust cover 5, stable connection is easy for installation, and described point
Easy to connect to be threadedly coupled between pump cylinder 1 and bleed screw 6, the stop collar 3 is spring steel construction stop collar, limit
Effect is good, and good toughness is not easy to break.
Working principle: the outer end of two component pump pistons 4 is connect with brake block push rod respectively, and sealing cup 2 plays sealing and makees
With preventing oil leak, bleed screw 6 passes through the oil transportation of 1 top rear of wheel cylinder cylinder body for the exhaust in wheel cylinder cylinder body 1, hydraulic oil
Mouth enters the inner cavity of wheel cylinder cylinder body 1, and hydraulic oil high pressure pushes the inner end of two component pump pistons 4, make wheelcylinder piston 4 to
Outer promotion brake block push rod is mobile, and wheelcylinder piston 4 drives and moves outside stop collar 3, when the friction of outer friction piece is larger, due to limit
The inner cavity of position ring 3 and wheel cylinder cylinder body 1 is interference fit, and the spring supporting dynamics on brake block can only support wheelcylinder piston 4 slightly
Micro- return loosens, and cannot push wheelcylinder piston 4 that stop collar 3 is driven to reset completely, in this way, when the pad wear that brakes is larger, point
The stroke that pump piston 4 is displaced outwardly is still shorter, and brake block can continue to use.
While there has been shown and described that the embodiments of the present invention, for the ordinary skill in the art,
It is understood that these embodiments can be carried out with a variety of variations in the case where not departing from the principles of the present invention and spirit, repaired
Change, replacement and variant, the scope of the utility model is defined by the appended claims and the equivalents thereof.
