Description
Technical field
The present invention relates to vehicle Charge device technical fields, more particularly to a kind of booster input shaft knot of adjustable load
Structure.
Background technique
As shown in Figure 1, spring 1 is fixed in input shaft body 2, for controlling piston, spring force will not under normal circumstances
It is changed, removes non-demolition input shaft ontology 2；The input shaft body 2 of existing design is merely capable of providing a kind of bullet of consecutive variations
Spring force.
However, sometimes we need a series of variable spring forces and on the basis of not destroying input shaft, moreover, I
Do not need to change the input shaft that entirely assembles, this needs is spent too much of his time.Therefore, when we need to remove adjustment bullet
When spring force, a kind of new design is needed.
Summary of the invention
(1) technical problems to be solved
The size of realization adjustment spring power the technical problem to be solved by the present invention is to how easily, without changing
The overall structure of input shaft.
(2) technical solution
In order to solve the above technical problem, the present invention provides a kind of booster input shaft structure of adjustable load, including it is defeated
Enter shaft body, one end of the input shaft body is arranged with spring, and the other end of the input shaft body is equipped with screw thread, described defeated
Enter and be also arranged with sleeve in shaft body between the screw thread and spring, the outer end of the spring is fixed by fixation member, institute
The inner end and the sleeve for stating spring are abutted together, on the screw thread twist be equipped with nut, the other end of the sleeve with it is described
Nut is abutted together, and by nut described in turn, adjusts the elastic of the spring, to adjust the spring force of the spring.
Wherein, washer can be equipped between the spring and sleeve and between sleeve and nut.
(3) beneficial effect
Compared with prior art, the invention has the following advantages that
A kind of booster input shaft structure of adjustable load provided by the invention, input shaft body it is opposite with spring one
End setting screw thread, and sleeve is added in input shaft body, it is supported by being arranged on screw thread with the nut being threadedly engaged, sleeve
It leans against between spring and nut, the elastic of the spring is adjusted by nut described in turn for transmission force, to adjust institute
State the spring force of spring.
The present invention does not need to carry out input shaft big change, and screw thread is only arranged on input shaft, can realize
Purpose is stated, it is easy to operate.
Detailed description of the invention
Fig. 1 is prior art booster input shaft structure schematic diagram；
Fig. 2 is a kind of structural schematic diagram of the booster input shaft structure of adjustable load of the present invention.
In figure: 1: spring；2: input shaft body；3: sleeve；4: nut；5: washer；6: fixation member.
Specific embodiment
With reference to the accompanying drawings and examples, specific embodiments of the present invention will be described in further detail.Implement below
Example is not intended to limit the scope of the invention for illustrating the present invention.
In the description of the present invention, it should be noted that term " center ", " longitudinal direction ", " transverse direction ", "upper", "lower",
The orientation or positional relationship of the instructions such as "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom" "inner", "outside" is
It is based on the orientation or positional relationship shown in the drawings, is merely for convenience of description of the present invention and simplification of the description, rather than instruction or dark
Show that signified device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore should not be understood as pair
Limitation of the invention.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " installation ", " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, can also can be indirectly connected through an intermediary
Connection inside two elements.For the ordinary skill in the art, it specifically can optionally understand that above-mentioned term exists
Concrete meaning in the present invention.
As shown in Fig. 2, being a kind of booster input shaft structure of adjustable load provided in an embodiment of the present invention, including input
Shaft body 2, one end of the input shaft body are arranged with spring 1, and the other end of the input shaft body 2 is equipped with screw thread, described
Shaft body is upper that sleeve 3 is also arranged between the screw thread and spring 1 for input, and the outer end of the spring 1 is consolidated by fixation member 6
Fixed, the inner end of the spring 1 is abutted together with the sleeve 3, is twisted on the screw thread equipped with nut 4, the sleeve 3 it is another
End is abutted together with the nut 4, transmits nut 4 to the power of spring 1 by sleeve 3, and when nut 4 described in the turn can
The elastic of the spring 1 is adjusted, to adjust the spring force of the spring 1.And it does not need to carry out input shaft body 2 big
Change, it is easy to operate, it is easy to accomplish.
In the embodiment of the present invention, can it be equipped between the spring 1 and sleeve 3 and between sleeve 3 and nut 4
Washer 5 causes to wear and sleeve 3 directly contacts with nut 4 and causes to wear to prevent spring 1 from directly contacting with sleeve 3, with
Extend the service life of spring 1, sleeve 3 and nut 4.The length that sleeve 3 can also be adjusted by increase and decrease washer 5, meets spiral shell
The demand that mother 4 is adjusted.
As can be seen from the above embodiments, the present invention can easily realize the size of adjustment spring power, and not need to change
Become the overall structure of input shaft.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
