Abstract
The utility model discloses a kind of through ball-and-nut steering gear, include a housing, the top of described housing is provided with a piston and a screw shaft, the bottom of described housing is provided with an output shaft, the head of described screw shaft is provided with a valve element, and the side of described piston is provided with a upper cavity, and the opposite side of described piston is provided with a lower chamber, the afterbody of described screw shaft is provided with an oil-out, and described screw shaft runs through described housing.Because screw shaft both ends support, improve transmission and stress performance, stability is preferable, and feel is moderate, turns to reliable.
Description
Technical Field
The utility model relates to an automobile commutator, more exactly, be a through type recirculating ball steering gear.
Background
The non-through type axial clearance of the existing automobile commutator is large, the clearance adjustment is difficult, and the screw shaft is supported by only one end and is easy to be stressed unevenly.
SUMMERY OF THE UTILITY MODEL
The utility model discloses solve the technical problem that prior art exists to a through recirculating ball steering gear is provided.
The above technical problem of the present invention can be solved by the following technical solutions:
the through type circulating ball steering gear is characterized by comprising a shell, wherein a piston and a screw shaft are arranged on the upper portion of the shell, an output shaft is arranged on the lower portion of the shell, a valve core is arranged at the head of the screw shaft, an upper cavity is arranged on one side of the piston, a lower cavity is arranged on the other side of the piston, an oil outlet is formed in the tail portion of the screw shaft, and the screw shaft penetrates through the shell.
As the preferred embodiment of the utility model, the shell is integrally formed by aluminum castings.
This through recirculating ball steering gear simple structure, the effect is obvious, low cost, and the practicality is strong, has following advantage:
(1) the two ends of the screw shaft are supported, so that the transmission and stress performance is improved, the stability is better, the hand feeling is moderate, and the steering is reliable;
(2) the assembly precision is high, the axial clearance is small, and the straight driving precision is high;
(3) compact structure and convenient installation.
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 through type recirculating ball steering gear of the present invention;
wherein,
1. a through type recirculating ball diverter; 2. a housing; 3. a piston; 4. a screw shaft; 5. an output shaft; 6. an upper cavity; 7. a lower cavity; 8. a valve core; 9. and an oil outlet.
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, the through-type recirculating ball steering gear 1 includes a housing 2, a piston 3 and a screw shaft 4 are disposed at an upper portion of the housing 2, an output shaft 5 is disposed at a lower portion of the housing 2, a valve core 8 is disposed at a head portion of the screw shaft 4, an upper cavity 6 is disposed at one side of the piston 3, a lower cavity 7 is disposed at the other side of the piston 3, and an oil outlet 9 is disposed at a tail portion of the screw shaft 4. The screw shaft 4 penetrates the housing 2. The housing 2 is integrally formed of an aluminum casting.
When the steering gear works, the vehicle is in a straight-line driving position. When the steering wheel is driven to the right, oil enters the upper cavity 6 from the oil inlet through the valve core 8, the upper cavity 6 is a high-pressure cavity at the moment, and the piston 3 moves to the right to drive the output shaft 5 to rotate to the right. When the steering wheel is turned leftwards, oil enters the lower cavity 7 from the oil inlet through the valve core 8, the lower cavity 7 is a high-pressure cavity at the moment, and the piston 3 moves leftwards to drive the output shaft 5 to rotate leftwards. The rotation of the output shaft 5 drives the other transmission mechanisms, thereby realizing the steering function.
This through recirculating ball steering gear simple structure, the effect is obvious, low cost, and the practicality is strong, has following advantage:
(1) the two ends of the screw shaft are supported, so that the transmission and stress performance is improved, the stability is better, the hand feeling is moderate, and the steering is reliable;
(2) the assembly precision is high, the axial clearance is small, and the straight driving precision is high;
(3) compact structure and convenient installation.
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.
Claims (2)
