Abstract
The utility model discloses a kind of volume infinitely variable air spring additional air chambers, are related to air spring for automobile auxiliary chamber technical field.Specifically include that the additional variable gas chamber of internal screw thread outer sleeve and external screw thread inner sleeve composition, connect the connecting line of main air chamber, wherein there is card slot on internal screw thread outer sleeve, card slot and fixed card buckle cooperate, so that internal screw thread outer sleeve can only move along a straight line up and down and cannot rotate, the centre bit of external screw thread inner sleeve bottom is equipped with the attachment device of transmitting Motor torque.The auxiliary chamber can realize the stepless variation of auxiliary chamber volume by control external screw thread inner sleeve rotation, the rotation of external screw thread inner sleeve is driven by motor, it is transmitted by thread mechanism, internal screw thread outer sleeve is driven to move up and down, change the volume between two sleeves, thus realize that auxiliary chamber dischargeable capacity changes, the final rigidity for changing air spring system, to meet the various driving cycles of vehicle, achieve the purpose that improve airsuspension system comprehensive performance.
Description
Technical field
The utility model relates to automobile air spring auxiliary chamber technical fields, the in particular to air spring of variable volume
Auxiliary chamber.
Background technique
Air spring is the important component of air spring suspension systems, and air spring passes through air in sealed volume
Compressibility realizes its elastic reaction, has the function of support, buffering, vibration isolation etc..The rigidity of air spring is that influence automobile is comfortable
Property an important factor for one of, spring rate is smaller, and vehicle body intrinsic frequency is lower, and vehicle running smoothness is better, but operates steady
It is qualitative accordingly to reduce, cause automobile to timely feedback decrease for what driver operated, automobile is reduced to jamproof ability.
When encountering different operating conditions in vehicle traveling process, different spring rates is needed, it can be by changing air spring additional air chamber
Volume changes air spring rigidity characteristic, and air spring rigidity increases with auxiliary chamber volume and reduced.Existing patent document
Auxiliary chamber is divided into three " sub- gas by " a kind of variable auxiliary chamber air spring constructions " (application number 201520817980.4)
Room " changes the volume of auxiliary chamber by adjusting auxiliary chamber ventilating control valve, and defect is: three sub- gas chamber volumes are solid
It is fixed, cannot just operating condition made most effective adjusting at that time, and control valve is more, and control flow is complicated, and frequent inflation/deflation causes
The loss of engine power.
Utility model content
The utility model is complicated with regard to existing air spring additional air chamber control, airtightness is bad, and it is solid to can be changed gas chamber volume
In the case where fixed, propose a kind of volume infinitely variable, do not need inflation/deflation, while only being rotated by external screw thread inner sleeve
It can be changed auxiliary chamber to adjust the air spring of dischargeable capacity size, to change air spring rigidity.
Its technical solution is: a kind of volume infinitely variable air spring additional air chamber includes by internal screw thread housing
The additional variable gas chamber of cylinder and external screw thread inner sleeve composition, the connecting line being connect with air spring main air chamber, wherein internal screw thread
There is card slot on outer sleeve, the attachment device of transmitting Motor torque is arranged at external screw thread inner sleeve bottom.
Further, the card slot on the internal screw thread outer sleeve is by blocking the fixation device on vehicle frame, in external screw thread
Internal screw thread outer sleeve is made to realize direct acting up and down during sleeve rotating, without following the shapes such as rotation, left and right displacement
Condition.
Further, the external screw thread inner sleeve, which is driven by a motor, makes rotating motion, and transmits torque, band by thread mechanism
Dynamic internal screw thread outer sleeve does direct acting up and down, and then changes the volume of air spring additional air chamber, provides a kind of stepless variation
Variable volume.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Fig. 2 is the state diagram disclosed in the utility model that stepless can change when gas chamber volume reaches maximum.
In figure: connecting line 1, card slot 2, internal screw thread outer sleeve 3, external screw thread inner sleeve 4, transmission shaft 5.
Specific embodiment:
The course of work of the utility model is described further in the following with reference to the drawings and specific embodiments, but not as right
The restriction of the utility model.
As shown in Figure 1, 2, a kind of volume infinitely variable air spring additional air chamber, including 3 He of internal screw thread outer sleeve
External screw thread inner sleeve 4 form it is additional can stepless variation gas chamber, be connected to the connecting line 1, In at 3 top of internal screw thread outer sleeve
The card slot 2 processed on internal screw thread outer sleeve 3, and it is connected to the composition of transmission shaft 5 of 4 lower section of external screw thread inner sleeve.
The connecting line 1 is connected to air spring main air chamber, and the internal screw thread outer sleeve 3 blocks vehicle frame by card slot 2
On fixation device, the transmission shaft 5 connects motor.
Working principle of the utility model is: ECU control motor operating, motor driven transmission shaft 5, the transmission shaft 5 will be electric
The torque of machine passes to external screw thread inner sleeve 4, and by internal and external threads engaged transmission, the external screw thread inner sleeve 4 transmits torque
To internal screw thread outer sleeve 3, the internal screw thread outer sleeve 3 blocks the fixation device on vehicle frame by card slot 2, to realize in described
The direct acting up and down of thread jacket cylinder 3, and then change the additional gas being made of the internal screw thread outer sleeve 3 and external screw thread inner sleeve 4
The dischargeable capacity of room, the stepless variation of air spring additional air chamber dischargeable capacity realize the rigidity for changing air spring.
There are two limiting conditions for the utility model:
As shown in Figure 1, working state schematic representation when being the dischargeable capacity chamber minimum of the utility model, outside the internal screw thread
Sleeve 3 is in bottom, and infinitely variable air spring additional air chamber volume is minimum at this time.When needing dischargeable capacity to increase
When, ECU control motor rotates counterclockwise, and then drives the rotation counterclockwise of external screw thread inner sleeve 4, the internal screw thread housing
The upward vertical movement under the transmission of thread mechanism of cylinder 3, and do not rotate or move left and right, when reaching desired volume,
ECU control motor stops rotating.
As shown in Fig. 2, working state schematic representation when being the dischargeable capacity chamber maximum of the utility model, outside the internal screw thread
Sleeve 3 is in topmost, and infinitely variable air spring additional air chamber volume is maximum at this time.When needing dischargeable capacity to reduce
When, ECU control motor rotates clockwise, and then the external screw thread inner sleeve 4 is driven to rotate clockwise, the internal screw thread housing
The vertical downward movement under the transmission of thread mechanism of cylinder 3, and do not rotate or move left and right, when reaching desired volume,
ECU control motor stops rotating.
The utility model is not limited to above-mentioned specific implementation method, all similar structures and phase using the utility model
Like variation, it is included in the protection scope of the utility model.
