Description

The car gear shifting linkage

Technical field

But the utility model relates to a kind of automobile at the starting or the car gear shifting linkage of automatic compensation parking brake and power-transfer clutch during gear shift.

Background technology

The automobile that hand-operated transmission is installed at present is when starting, and the step that needs is to start, step on power-transfer clutch, engage a gear, RELEASE PARKINGBRAKE, lift power-transfer clutch and make its semi-linkage, oil supply, loosen the clutch automobile enter normal enforcement usually.And when needing gear shift in vehicle traveling process, its step has reduced this link of RELEASE PARKINGBRAKE on the basis of the above.In repeating the process of above-mentioned action, because misoperation will cause power-transfer clutch, the reduction in change speed gear box life-span, increased the car opertion cost, the energy of chaufeur is disperseed, cause traffic accident easily.

Summary of the invention

This uses later-model purpose is to overcome above-mentioned the deficiencies in the prior art, provide a kind of when the gear shift of vehicle starting and driving process, can realize disengaging, RELEASE PARKINGBRAKE, power-transfer clutch semi-linkage, the clutches engaged of power-transfer clutch automatically, overcome the car gear shifting linkage of human element the autoclutch influence.

For realizing the purpose of this utility model, the technical scheme that is adopted is: a kind of car gear shifting linkage, comprise power-transfer clutch, change-speed box handle, parking brake device and hand switch, it is characterized in that motor drives cam mechanism by driving device and rotates, during the cam uniform rotation, its outline drive transmission device links to each other with power-transfer clutch; With cam coaxial link to each other two shift forks are arranged, two shift forks whenever rotate a circle and all can drive fork I relative with it and fork II swing, fork II links to each other with fork I by connection lead II, fork I passes through connection lead I and links to each other with the parking brake device; The disk cam that cam is that power-transfer clutch is opened by being used for, power-transfer clutch separation fully, semi-linkage, four sections curves of clutches engaged form; Hand switch links to each other with motor by control circuit.

The characteristics of technique scheme are in vehicle starting or driving process during gear shift, only need press hand switch, just can make the motor rotation, thereby driving cam mechanism rotates, by just realizing opening of autoclutch automatically with cam mechanism, power-transfer clutch separates fully, semi-linkage, four processes of clutches engaged, simultaneously by parking brake being unclamped automatically with coaxial two shift forks that link to each other of cam, from having realized the process of the automatic coordinated control the automobile variable speed process, avoided because misoperation causes power-transfer clutch, the reduction in change speed gear box life-span can effectively prolong its service life.

In order to make the technical program reach convenient, succinct purpose from structure and control, above-mentioned motor adopts stepping motor, and the above-mentioned driving device that rotates by the driven by motor cam mechanism is worm gear, worm reduction gear; Above-mentioned connection lead is the Bowden cable line; Above-mentioned hand switch is installed on the change-speed box handle.

Above-mentioned driving device is the outline moving contact of an end and cam, and the rod member that an end is fixedly hinged links to each other with rod member with an end, and the connection lead that the other end links to each other with power-transfer clutch is formed.

Above-mentioned driving device is that the outline of cam directly links to each other with power-transfer clutch.

In sum, the utility model is on the structure of existing hand gear automobile, installed and to have realized the automobile automatic gear shifting linkage, in automobile starting or driving process, the alternative use has transmission system now, can use also that the technical program describedly can make automatically that autoclutch is opened, power-transfer clutch separation fully, semi-linkage, parking brake are unclamped automatically, the device of clutches engaged, the utility model also has following characteristics on the whole.

1, easy to operate.When in vehicle starting or driving process, needing gear shift, replaced the manual operation process with this device, only need press hand switch, before the change-speed box handle enters desired location, this device just can be realized the separation of power-transfer clutch automatically and mesh whole process, so after this device is installed, during speed change only need one push away oiling by one, just can realize the whole process of speed change automatically.

2, rational in infrastructure, stability is high.Because structures such as cover shift fork, connecting rod and Bowden cable line that adopted cam mechanism and matched with it make this install stable performance in use.

Description of drawings

Fig. 2 is the schematic rear view of the utility model accompanying drawing 1;

Fig. 3 is the partial top view of the cam mechanism part of the utility model Fig. 2.

The specific embodiment

As shown in Figure 1, on the gear change hand lever 8 of automobile gearbox 9, hand switch 7 is installed, hand switch 7 links to each other with control circuit 14, it is that control step motor 13 rotates that this control circuit mainly acts on, delay timer is installed in control circuit simultaneously, can realize by a hand switch that by regulating delay timer stepping motor drives cam 6 and rotates a circle.All can be parked in the initial position for guaranteeing that cam 6 whenever rotates a circle, the reset motor device can be installed on stepping motor, overcoming accumulated error, the rotating cycle of accuracy control motor and angle, this device is a present stepping motor control setup commonly used.Worm screw 12 links to each other with stepping motor, drives worm gear 10 by worm screw and rotates.Worm gear links to each other with axle 11 by key, also is installed with cam 6 and two

shift forks

21,22 on axle 11, as shown in Figure 2.The reference position of cam 6 as shown in Figure 1.When vehicle starting, press hand switch 7, the stepping motor energising drives cam 6 conter clockwise uniform rotation, at this moment the profile of cam orders about an end by the rod member 4 cws swing that hinge 3 is fixedly hinged, and drives power-transfer clutch 1 by coupled connection lead 2 and enters released state; When cam 6 be rotated further maximum eccentric apart from the time, power-transfer clutch separates fully.Pressing transmitting ratio that hand switch separates rotating speed that this time can be by adjusting stepping motor or turbine, scroll bar fully to power-transfer clutch makes it at 0.5-3 between second.At this moment just the change-speed box handle can be pushed required gear.Cam 6 is rotated further, and the eccentric distance on the cam 6 reduces gradually, and rod member 4 rotates counterclockwise by connection lead 2 drive power-transfer clutchs 1 order and enters semi-linkage and clutches engaged state.In said process, enter the curve of semi-linkage when cam 6 after, shift fork 21 contacts with fork I 18, drive its counter-clockwise swing, link to each other with fork I 18 by an end, the connection lead I 17 that the other end links to each other with parking brake device 15 unclamps the parking brake device, drives shift fork 22 left-hand revolutions by connection lead II 20 simultaneously.After cam 6 continued to rotate to the clutches engaged curve, shift fork 22 contacted with fork II 23, drives its counter-clockwise swing, drove fork I 18 by connection lead II 20 and resetted.After cam 6 rotates a circle, stop automatically.

When stopping, the pull-up parking brake, connection lead I 17 is tightened up, for action next time is got ready.

By foregoing description, disk cam 6 is the closed curves by power-transfer clutch is opened, power-transfer clutch separation fully, semi-linkage, four sections curves of clutches engaged form as can be seen.

For realizing that better the above-mentioned connection lead of the technical program is the Bowden cable line.On fork I 18 or fork II 23, retracing spring 24 is installed.

Turbine worm, cam 6, shift fork 21, shift fork 22 position on axle concerns as seen in Figure 3.
