Abstract
The utility model discloses a car power steering gear piston stroke mechanism. The car power steering gear piston stroke mechanism comprises an outer shell and a piston. The piston is arranged inside the outer shell. A right one-way valve and a left one-way valve are arranged inside the piston. A left valve core and a right valve core are respectively arranged on two neighboring ends of the left one-way valve and the right one-way valve. A laminated spring used for quickly restoring the left one-way valve and the right one-way valve is arranged between the left valve core and the right valve core. Due to the fact that a circle of circular ring smaller than the outer diameter of a connecting pipe is arranged at the lower end of the connecting pipe, breakage does not occur due to uneven stress when a user uses a plate heat exchanger.
Description
Technical field
The utility model relates to the automotive converters field, particularly relates to a kind of automobile power steering piston stroke mechanism.
Background technology
Present piston travel unloading mechanism of automobile power steering gear, comprise the automobile power steering shell that is connected to form by lower house and upper shell, piston is arranged in the plunger shaft of automobile power steering shell, a unloading hole that connects two end faces in piston left and right is arranged on piston, position near the right side in unloading hole is installed with the right check valve that is comprised of right valve pocket and right spool, the push rod of right spool stretches out the right side of piston, and the opening direction of right check valve is for from right to left; Near the position of left side, the left check valve that is comprised of left valve pocket and left spool is installed in unloading hole, the push rod of left spool stretches out the left side of piston, and the opening direction of left check valve is for from left to right; Between right check valve and left check valve, retracing spring is arranged, the inner end surface of right spool and left spool is withstood respectively at the two ends of retracing spring, position-limited lever is through the center of retracing spring, the distance the when length of position-limited lever is all closed less than left and right check valve between right spool and left spool inner end surface; Also comprise right regulating sleeve and left regulating sleeve; The shortcoming of this structure is:; Between right check valve and left check valve, retracing spring is arranged, the easy stretching of spring, mutability, spring of long duration can follow the string, and causes right check valve and left check valve to reset.
The utility model content
The technical matters that the utility model mainly solves is to provide a kind of automobile power steering piston stroke mechanism, can solve the right check valve of traditional deflector piston stroke mechanism and the problem that left check valve can't reset.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of automobile power steering piston stroke mechanism is provided, comprise shell and piston, the piston setting in the enclosure, the inside of piston is provided with right check valve and left check valve, two ends that left check valve is adjacent with right check valve are respectively equipped with left spool and right spool, be provided with between described left spool and right spool for left check valve and the right check valve folded spring that resets rapidly, it is short that folded spring has stroke, load is large, requisite space is little, is used in combination conveniently, and is not yielding, safe.
The beneficial effects of the utility model are: right check valve and left check valve are resetted rapidly, and load is large, requisite space is little, is used in combination conveniently, and is not yielding, safe.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The specific embodiment
Disclosed all features in this specification sheets, or the step in disclosed all methods or process except mutually exclusive feature and/or step, all can make up by any way.
Disclosed arbitrary feature in this specification sheets (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or similar characteristics.
As shown in Figure 1, a kind of automobile power steering piston stroke described in the utility model mechanism, comprise shell 1 and piston 2, piston 2 is arranged in shell 1, the inside of piston 2 is provided with right check valve 3 and left check valve 4, two ends that left check valve 4 is adjacent with right check valve 3 are respectively equipped with left spool 5 and right spool 6, are provided with between left spool 5 and right spool 6 for left check valve 4 and the right check valve 3 folded spring 7 that resets rapidly.Right check valve and left check valve are resetted rapidly, and load is large, requisite space is little, is used in combination conveniently, and is not yielding, safe.
The utility model is not limited to the aforesaid specific embodiment.The utility model expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
