Description
The utility model relates to a kind of vehicular clutch fool proof drive that adopts vacuum booster, belongs to vehicular spare parts
Technical field.
For the operating control of car and light passenger-cargo carriage friction clutch, use fluid pressure type steering unit more generally at present.Hydraulic control mechanism mainly is made up of foot pedal lever mechanism, clutch master cylinder, pipeline, clutch slave cylinder.Chaufeur is stepped on joint that the dynamic clutch pedal operates the clutch and is separated.Because each conversion gear and glancing impact all need step pedal of clutch, frequent manipulation brings fatigue to chaufeur.
The purpose of this utility model is a kind of vehicular clutch fool proof drive that adopts vacuum booster of design, can be applicable to adopt the friction clutch of hydraulic control mechanism, under the prerequisite of not changing power-transfer clutch inner structure and part hydraulic control mechanism, by increasing automatic controller, make vehicle at starting, gear shift and glancing impact, the separation of automatic guidance power-transfer clutch with engage.
The utility model design-calculated adopts the vehicular clutch fool proof drive of vacuum booster, comprises worm gear, worm screw, set pin, torsion spring, fork, vacuum booster and clutch master cylinder.Wherein worm screw is a driving link, and worm gear and worm screw are meshing with each other, and set pin is fixed on the worm gear, one end of fork and set pin relative fixed, the input push rod of the other end and vacuum booster is hinged, and the swing fulcrum place of fork is provided with torsion spring, and vacuum booster is connected with clutch master cylinder.
The utility model is applicable to the friction clutch that all adopt hydraulic control mechanism, can not change the inner structure and the part steering unit of friction clutch, can not produce any harmful effect to the original performance of automobile.Mechanism is simple, and cost is low, is easy to arrange and implement, and all can improve the vehicle of having gone into operation or used, makes the manipulation automation of power-transfer clutch.
Characteristics of the present utility model are:
1, adopted vacuum booster as the major impetus element, can adopt the vacuum booster of different power-assisted ratios, so that adopt the miniwatt driving motor according to different vehicles.
2, the power of cut-off clutch is provided by mechanical vacuum booster and torsion spring, and electrical motor only plays switch, and behind disengaging of clutch, electrical motor can cut off the power supply.The mutual balance of elastic force with power-transfer clutch elastic element (as diaphragm spring) of making a concerted effort of spring force, vacuum power makes power-transfer clutch keep released state.
3, the engaging process of power-transfer clutch is the process of electrical motor by worm and gear compression torsion spring simultaneously, after the worm gear rotation makes set pin touch support, support balances each other by the counter-force and the torsion spring power of set pin to fork, makes torsion spring remain on the energy storage state.
Description of drawings:
Fig. 1 is a mechanism principle scheme drawing of the present utility model.
Fig. 2 is the principle of work scheme drawing of the utility model in the process of operating the clutch.
The label of each components and parts is identical among Fig. 1 and Fig. 2, wherein: the 1st, DC machine, the 2nd, worm screw, the 3rd, worm gear, the 4th, set pin, the 5th, garden post torsion spring, the 6th, fork, the 7th, mechanical vacuum booster, the 8th, clutch master cylinder, the 9th, clutch slave cylinder, the 10th, wheel cylinder pull back spring, the 11st, disengaging yoke, the 12nd, release thrust bearing, the 13rd, separate and to refer to, the 14th, platen, the 15th, clutch driven disc assembly, the 16th, engine flywheel.
Below in conjunction with Fig. 1 and Fig. 2 principle of work of the present utility model is described.
The utility model mainly comprises mechanical vacuum booster, swing-bar mechanism and worm type of reduction gearing and former clutch hydraulic pressure steering unit (master cylinder, pipeline, clutch slave cylinder) etc.DC motor 1 links to each other with worm screw 2, drives worm gear 3 and rotates, and the set pin 4 on the worm gear 3 is hinged with an end of fork 6, and the input push rod of the other end of fork 6 and vacuum booster 7 is hinged, and is provided with torsion spring 5 at the hinge place of fork 6 and support.The output push rod of vacuum booster 7 is connected with the piston push rod of clutch master cylinder 8 and manufactures one.
When power-transfer clutch remained on engagement state, torsion spring 5 was in maximum energy storage state, and fork 6 is subjected to the effect of two power: the torque T of the directed force F of worm gear set pin 4 and torsion spring 5, the mutual balance of two power makes fork 6 be in stable quiescence.This moment, worm gear set pin 4 contacted at the B point with support, the mutual balance of application force of support and 6 pairs of set pins of fork, and promptly the suffered mutual balance of external force of worm gear keeps quiescence.
When power-transfer clutch need separate, electrical motor 1 drives worm gear 3 by worm screw 2 and rotates counterclockwise, set pin 4 slides in the slideway of fork 6, separate with support B point, the application force that fork 6 acts on set pin 4 produces a clws moment (being called for short fork moment) for worm gear center of gyration D, hinders worm gear and rotates; When worm gear rotates the line BD make set pin 4 and worm gear center D when vertical mutually with the AB section of fork 6, fork moment is zero, worm gear acceleration rotation; When worm gear continued to rotate counterclockwise, torsion spring 5 discharged elastic energy, makes fork moment become anticlockwise direction, becomes the propulsion source that worm gear rotates, and with the motor force combined action, made worm gear quicken to rotate counterclockwise.Fork 6 cws swing simultaneously, the input push rod of promotion vacuum booster 7, under the auxiliary promotion of vacuum power, clutch master cylinder 8 is set up hydraulic coupling, disengages the clutch.
In the released state of power-transfer clutch, the elastic force of torsion spring 5 acts on servo-unit input push rod by the hinge C of fork 6, and does not have application force between fork 6 and the set pin 4.In design, choose suitable mechanics parameter, the power of cut-off clutch is provided by mechanical vacuum booster 7 and torsion spring 5,1 of electrical motor plays switch like this, behind disengaging of clutch, electrical motor can cut off the power supply, and keeps released state by spring force and vacuum power.
When power-transfer clutch need engage, electrical motor 1 drove worm gear 3 by worm screw 2 and clockwise rotates, and set pin 4 slides in the slideway of fork 6, promote fork 6 counter-clockwise swings, vacuum booster 7 is return under the pull back spring effect, clutch master cylinder 8 releases, clutch engagement.During fork 6 counter-clockwise swings, torsion spring 5 is compressed, and worm gear 3 clockwise rotates the state vertical with fork AB by BD, fork moment becomes clockwise direction from conter clockwise, set pin 4 contacts with support at the B point, and torsion spring 5 remains on the energy storage state, and clutch's jointing process finishes.
In former clutch hydraulic pressure steering unit, the structure of clutch slave cylinder and oil pipe and installation site, mounting means are constant.According to the thrust of clutch-diaphragm spring, calculate the required line pressure of cut-off clutch, be applied to the thrust on the clutch master cylinder piston push rod, and then calculate the piston area and the diameter of piston of vacuum booster.Consider the variation of atmospheric pressure, when calculating the booster piston diameter, need leave certain surplus, so just guaranteed that vacuum booster can both provide enough thrust in all cases, disengage the clutch with external factor such as sea level elevations.Select suitable vacuum booster according to the aforementioned calculation result.Structure to the clutch master cylinder piston push rod is improved design, is connected with servo-unit output push rod, simultaneously clutch master cylinder and servo-unit is fabricated to one.Connect vacuum booster and vacuum tank (or engine intake manifold) with vacuum hose, for vacuum booster provides vacuum source.
