The utility model discloses solve the technical problem that prior art exists to a recirculating ball steering gear with self-bleeding device is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the utility model provides a recirculating ball steering gear with automatic exhaust apparatus, its characterized in that, recirculating ball steering gear with automatic exhaust apparatus contain a valve body, the valve body on be equipped with an oil return hole, the oil return hole in be equipped with a detachable automatic exhaust apparatus, automatic exhaust apparatus's top be equipped with one and go up the accent, automatic exhaust apparatus contain a disk seat, the disk seat in be equipped with a spring and a steel ball, the top of steel ball be equipped with a locking ring, the bottom of disk seat be equipped with a gas vent, the top of disk seat be equipped with an inlet port.
As the preferred embodiment of the utility model, the bottom of the steel ball is provided with an air cavity which is communicated with the exhaust hole.
The utility model discloses a recirculating ball steering gear with self-bleeding device has following advantage: the utility model discloses a recirculating ball steering gear with self-bleeding device makes the inside air of steering gear discharge fast, and the sensitivity that improves the steering gear makes when turning to more smooth and easy, steady, noise reduction and vibration.
Drawings
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.
FIG. 1 is a schematic structural view of a recirculating ball steering gear with an automatic air-bleeding device according to the present invention;
fig. 2 is a schematic structural view of an automatic exhaust apparatus of the recirculating ball steering gear of fig. 1.
Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
As shown in fig. 1 and 2, the recirculating ball steering gear with an automatic exhaust device comprises a valve body 1, wherein an oil return hole 4 is formed in the valve body 1, a detachable automatic exhaust device 3 is arranged in the oil return hole 4, an upper cavity opening 2 is formed in the top of the automatic exhaust device 3, the automatic exhaust device 3 comprises a valve seat 6, a spring 7 and a steel ball 9 are arranged in the valve seat 6, a locking ring 10 is arranged at the top of the steel ball 9, an exhaust hole 5 is formed in the bottom of the valve seat 6, and an air inlet hole 11 is formed in the top of the valve seat 6.
The bottom of the steel ball 9 is provided with an air cavity 8, and the air cavity 8 is communicated with the exhaust hole 5.
The operation of the recirculating ball steering gear with automatic venting will now be described.
As shown in fig. 1, the automatic exhaust device 3 is installed on the end face of the valve body 1 and communicated with the oil return hole 4, the exhaust pressure is set to be 0.7-1.2MPa, when the upper cavity opening 2 starts to build pressure and the pressure is lower than 1.2MPa, the automatic exhaust device 3 is in an open state, the upper cavity opening 2 is communicated with the oil return hole 4, and the oil-gas mixture is discharged through the oil return hole 4; when the pressure of the upper cavity opening 2 is higher than 1.2MPa, the automatic exhaust device 3 is closed, and an exhaust action is completed at the moment, and when the action has a steering operation, the automatic exhaust device 3 continuously and repeatedly circulates to exhaust all air in the automatic exhaust device.
As shown in fig. 2, the automatic exhaust device 3 is composed of a valve seat 6, a spring 7, a steel ball 9 and a locking ring 10. When the pressure at the air inlet hole 11 is lower than 1.2MPa, the oil-gas mixture enters from the air inlet hole 11, the oil-gas mixture pushes the steel ball 9 to the left, the spring 7 is compressed under the stress, gaps are formed between the steel ball 9 and the locking ring 10 and between the steel ball 9 and the air cavity 8, the oil-gas mixture is communicated with the exhaust hole 5, and the automatic exhaust device 3 is in an open state. When the pressure at the air inlet hole 11 is higher than 1.2MPa, the oil-gas mixture enters from the air inlet hole 11, the oil-gas mixture pushes the steel ball 9 to the left, the spring 7 is pushed to the maximum, the steel ball 9 and the locking ring 10 form a large gap at the moment, the steel ball 9 and the air cavity 8 are sealed, the oil-gas mixture is not communicated with the exhaust hole 5, and the automatic exhaust device 3 is in a closed state.
The utility model discloses a recirculating ball steering gear with self-bleeding device has following advantage: the utility model discloses a recirculating ball steering gear with self-bleeding device makes the inside air of steering gear discharge fast, and the sensitivity that improves the steering gear makes when turning to more smooth and easy, steady, noise reduction and vibration.
Without being limited thereto, any changes or substitutions which are not thought of through creative efforts should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope defined by the claims.
