Description
Technical field
The utility model relates to automobile speed variator shift technical field, is specifically related to a kind of gear locking device based on forced maneuver formula speed changer automobile.
Background technology
The transmission control of current domestic heavy card automobile generally adopts rod-type control stick structure, they are some problems in use: especially occur phenomenon out of supply when road conditions difference or vibrations suddenly, reason out of supply has be each coordinate link lose damping action at two: one, the power produced in the displacement process of engine and driver's cabin has exceeded the coupling mechanism force of gear, and gear is taken off naturally.After realizing gear shift when the power of mechanical pull bar is delivered to shifting of transmission arm, in normal driving process, as occurred, road conditions shake suddenly the weight as liftable reducing bank at this moment mechanical pull bar itself, and the inertia force of generation can easily exceed the coupling mechanism force of gear, at this moment also can be out of supply.Two is because the coupling mechanism force of the gear locking spring of speed changer inside when new car dispatches from the factory there are certain requirements, and substantially can meet instructions for use, and with after a period of time, gear selecting moment and the engage a gear moment of speed changer have very large change.For problem out of supply, current automobile factory is general not in warranty coverage to this problem of vehicle after sale, uses client's also all helpless acceptance, gather together and use, but this problem is very important, likely causes serious traffic accident when problem is not too serious; When problem is very serious, can only by whole control stick structure integral replacing, the situation that gear selecting moment and engage a gear moment for speed changer change also needs to change locking spring, and this mode not only wastes resource, and costly, and service procedure is complicated.
Once disclose a kind of control mechanism of numerically-controlltransmission transmission with publication number 103453132A for the problems referred to above the applicant to be solved, but this agency cost is relatively high, market is in the urgent need to a kind of present situation based on former car, the more cheap anti-lost latch device that can reach again the pure frame for movement of effect of not losing rank of cost.
Summary of the invention
The purpose of this utility model is that the rod-type control stick coordinated with automotive transmission solving prior art existence is easily lost rank in the vertical, easily occurred the technical problem that joystick lever rocks in the horizontal.
For realizing this object, disclosed in the utility model, technical scheme is:
This gear locking device based on rod-type control stick, comprise damping memory cylinder 2, magnetic valve 3, press button 5, unlike the prior art: described damping memory cylinder 2 is double-acting cylinder, its cylinder body and vehicle frame hinged, its piston rod and existing automobile select gear shifting rocking arm 1 hinged; Described press button 5 is arranged on vehicle gearing handle 4; Air inlet/the exhaust outlet 22,23 of damping memory cylinder 2 piston 21 both sides is connected with two gas outlets 32,33 of magnetic valve 3 respectively; Folding between press button 5 to be connected with magnetic valve 3 electronic control module by wire 7 with two of Controlling solenoid valve 3 gas outlets 32,33.
Compared with prior art, the utility model does not change original automotive transmission control lever structure, by additional limited several pneumatic components and parts and press button, can realize locking gear level, structure is simple, with low cost, be not only applicable to car load manufacture, is also applicable to the transformation of vehicle after sale.

Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to accompanying drawing.
This gear locking device based on rod-type control stick, comprises damping memory cylinder 2, magnetic valve 3, press button 5, and described damping memory cylinder 2 is double-acting cylinder, its cylinder body and vehicle frame hinged, its piston rod and existing automobile select gear shifting rocking arm 1 hinged; Described press button 5 is arranged on vehicle gearing handle 4; Air inlet/the exhaust outlet 22,23 of damping memory cylinder 2 piston 21 both sides is connected with two gas outlets 32,33 of magnetic valve 3 respectively, damping remember cylinder 2 without the need to provide extra air force as gases at high pressure can complete the utility model intended the function that reaches and effect; Folding between press button 5 to be connected with magnetic valve 3 electronic control module by wire 7 with two of Controlling solenoid valve 3 gas outlets 32,33.
Normally hang up in certain grade of traveling process at automobile, two gas outlets 32 of magnetic valve 3, closed condition is between 33, air is possessed in air cavity due to piston 21 both sides, now piston 21 and piston rod are to move left and right, and need the air in the air cavity of compression piston 21 side, air in dilution piston 21 opposite side air cavity, therefore need to overcome the resistance therefore caused, and this resistance is reacted on by piston rod and selects on gear shifting rocking arm 1, thus define and select the state of gear shifting rocking arm 1 to make it be in the lock state, gear is finally made to be in the lock state, no matter how vehicle shakes, even if the coupling mechanism force of gear declines, each coordinates link to lose damping action also can not there is phenomenon out of supply on left and right directions is longitudinal.Simultaneously due to add damping memory cylinder 2 and with the hinged relationship selecting gear shifting rocking arm 1, vehicle frame, itself there is certain quality, hinged face has certain coefficient of friction, thus produce certain frictional force, this frictional force plays certain damping action, under greatly can being reduced in the situations such as engine resonance, road bumps, swinging and then being transmitted to the unordered technical problem of rocking of control crank transversely easily appears in the fore-and-aft direction that control stick occurs.
When not pressing press button 5, carry out gear shift/choosing when changing operation, the electronic control module of magnetic valve 3 does not still work, and be still in closed condition between two gas outlets 32,33 of magnetic valve 3, piston rod is in the lock state, cannot left and right displacement relative to paper, but can move forward and backward, therefore can carry out gear-change operation, but cannot gear selecting operation be carried out, namely can complete and pluck shelves operation, the operation from a transforming gear to another gear cannot be carried out.
When pressing the button switch 5, carry out gear shift/choosing when changing operation, the electronic control module work of magnetic valve 3, be in opening between two gas outlets 32,33 of magnetic valve 3, the air in the air cavity of piston 21 both sides of damping memory cylinder 2 can free flow, and piston and piston rod are in free state, can front, rear, left and right displacement relative to paper, therefore can carry out gear shift and gear selecting operation, not only can complete and pluck shelves operation, the operation from a transforming gear to another gear can also be carried out.
Above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to person skilled in the art can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.Hydraulic cylinder such as can be used to replace cylinder can realize identical function equally.All equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed within protection domain of the present utility model.
