Description

Stopping caliper

Technical field

The utility model relates to the stopping caliper field, especially a kind of stopping caliper.

Background technique

Original stopping caliper as shown in Figure 1, mainly comprise dial axis 1, first torsional stop 2, first spring 3, nut 4, push rod 5, O shape circle 6, screw rod 7, second torsional stop 8, spring seat 9, first jump ring 10, piston 11, rectangular loop 12, friction plate 13, dust-proof cover 14, second spring 15, rolling ring 16 and pad 17, spring inside diameter tolerance height in the former mechanism piston, not actual not accomplishing, be not suitable for producing in batches, and this mechanism's work is dumb, the riveted joint mode manufacturing efficiency that adopts is low, in actual production process the defect that Parking was lost efficacy often takes place.

Summary of the invention

The utility model will solve the shortcoming of above-mentioned prior art, and a kind of stopping caliper is provided.

The utility model solves the technological scheme that its technical problem adopts: this stopping caliper, mainly comprise dial axis, first torsional stop, first spring, nut, push rod, O shape circle, screw rod, second torsional stop, spring seat, first jump ring, piston, rectangular loop and friction plate, described dial axis is connected with an end of screw rod by push rod, be set with first torsional stop and second torsional stop on the screw rod, the other end of screw rod be installed in the piston after nut cooperates, be provided with pad between nut and the piston, the wavy spring sheet and second jump ring, the ear end face of piston compresses mutually with friction plate; First spring is installed in the spring seat, and first spring housing is contained on the nut, is connected with first jump ring on the spring seat.

The effect that the utility model is useful is: mechanism is more flexible, easy to manufacture in the existing piston, and assembling is easy, and rate of fault is less.Be fit to produce in batches.

Description of reference numerals: dial axis 1, the first torsional stop 2, the first springs 3, nut 4, push rod 5, O shape circle 6, screw rod 7, second torsional stop 8, spring seat 9, the first jump rings 10, piston 11, rectangular loop 12, friction plate 13, dust-proof cover 14, the second springs 15, rolling ring 16, pad 17, wavy spring sheet 18, the second jump rings 19.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

As shown in the figure, this stopping caliper, mainly comprise dial axis 1, first torsional stop 2, first spring 3, nut 4, push rod 5, O shape circle 6, screw rod 7, second torsional stop 8, spring seat 9, first jump ring 10, piston 11, rectangular loop 12 and friction plate 13, described dial axis 1 is connected with an end of screw rod 7 by push rod 5, and the head of screw rod 7 is equipped with O shape circle 6.Be set with first torsional stop 2 and second torsional stop 8 on the screw rod 7, the other end of screw rod 7 be installed in the piston 11 after nut 4 cooperates, be provided with pad 17, wavy spring sheet 18 and second jump ring 19 between nut 4 and the piston 11, the ear end face of piston 11 compresses mutually with friction plate 13; First spring, 3, the first springs 3 are installed in the spring seat 9 are sleeved on the nut 4, be connected with first jump ring 10 on the spring seat 9.Be set with dust-proof cover 14 on the described piston 11, be set with rectangular loop 12 on the piston 11.

Working principle:

1. Parking: when we rotate dial axis 1, by dial axis 1 push rod 5 is promoted toward the left side, by push rod 5 power is delivered on the screw rod 7,, power is delivered on the nut 4 again by screw rod 7 because the effect of torsional stop can not be rotated screw rod 7, because this moment, nut 4 was tangent with piston 11, produce frictional force, therefore, nut 4 can not rotate, promote to left movement thereby promote piston 11, promote friction plate 13 again and realize Parking.

2. driving: promoting piston 11 and move right when there is high oil pressure caliper inside, because this moment, nut 4 was not fitted with piston 11, is to rotate and fit in the rolling ring 16 on the left side.Therefore can drive nut and move forward, realize service brake.

In addition to the implementation, the utility model can also have other mode of executions.All employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
