Abstract
The utility model discloses an early warning device for reverse-gear shifting, which comprises a pressure sensor that is equipped on a reverse-gear shift block, wherein, the pressure sensor is connected with an input end of a single-chip microcomputer. The output end of the single-chip microcomputer is respectively connected with a voice reminder and a reverse-gear lock. The early warning device for reverse-gear shifting can prevent abrasion gear acceleration caused by reverse-gear shifting by a driver in error-operation condition and in driving process.
Description
Technical field
The utility model relates to a kind of automobile auxiliary device, and a kind of extension reverse gear prior-warning device particularly is applicable to that all kinds of automobiles hang reverse gear to prevent driver's mistake.
Background technique
In, the low side car reverses gear and itself do not contain synchronizer, car is hung under steam by mistake and can be existed gearbox to beat tooth when reversing gear, that is exactly the crown part enhance faster wear that causes gear, time grown, often, the crown at right angle has just been worn into fillet, interlock is not just thorough after going into retaining, and vibrations are easy to just to occur falling the phenomenon of retaining a little, have at this time just needed the overhaul gearbox.This just needs stop vehicle fully, allow clutch end speed be reduced to and reverse gear (at this time reverse gear is static) between speed discrepancy diminish, could guarantee that like this extension to reverse gear more smooth-going and do not beat tooth.Many times the driver does not come to a complete stop with hanging to reverse gear at once at car, and tooth just takes place to beat.Sometimes the driver is that mistake is hung reverse gear, and also there is potential danger in this to personnel on every side.
Summary of the invention
Defective or deficiency at the background technique existence, the purpose of this utility model is, a kind of extension reverse gear prior-warning device is provided, the prompting driver will hang reverse gear and utilize hydraulic type reverse gear lock to postpone allowing to hang reverse gear behind the certain hour when the driver attempts to hang reverse gear, and purpose is to remind the driver to think deeply whether this operation is misoperation.This can prevent that the driver from hanging and reverse gear and attempt to hang reverse gear under steam and the accelerating gear wearing and tearing under the misoperation situation.
In order to realize above-mentioned task, the utility model adopts following technical solution to be achieved:
A kind of extension reverse gear prior-warning device comprises the pressure transducer that is installed on the reverse gear shifting block, and described pressure transducer links to each other with the single-chip microcomputer input end, and the single-chip microcomputer output terminal is connected with voice prompting device and reverse gear lock respectively.
Some other characteristics of the present utility model are:
Described pressure transducer is installed on the reverse gear shifting block.
Described reverse gear lock is hydraulic type.
The utility model is a kind of extension reverse gear prior-warning device, can prevent from that the driver from hanging reverse gear and attempt to hang reverse gear under steam and the accelerating gear wearing and tearing under the misoperation situation.
Description of drawings
Fig. 1 is structured flowchart of the present utility model.
Fig. 2 is speed variator reverse gear lock device structural drawing.
Fig. 3 is flow chart of the present utility model.
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
Referring to Fig. 1, present embodiment provides a kind of concrete structure of hanging the reverse gear prior-warning device, comprises the pressure transducer that is installed on the reverse gear shifting block, wherein, described pressure transducer links to each other with the single-chip microcomputer input end, and the single-chip microcomputer output terminal is connected with voice prompting device and reverse gear lock respectively.
The prompting driver will hang reverse gear and utilize hydraulic type reverse gear lock to postpone allowing to hang reverse gear behind the certain hour when the driver attempts to hang reverse gear, and this reminds the driver to think deeply whether this operation is misoperation.Comprise the pressure transducer that is installed on the reverse gear shifting block, pressure transducer connects a single-chip microcomputer, is connected with voice prompting device and hydraulic type reverse gear lock on the single-chip microcomputer.
Pressure transducer is used for gathering the pressure information on the reverse gear shifting block, single-chip microcomputer for the treatment of pressure information, judge whether the driver has and hang the reverse gear intention, give an order to voice prompting device and hydraulic type reverse gear lock, voice prompting device is used for the prompting driver and considers whether hang into reverse gear, and hydraulic type reverse gear lock is used for postponing to hang the reverse gear time.
In the present embodiment, single-chip microcomputer is selected the AT89C51 single-chip microcomputer, and pressure transducer is selected the HM10 pressure transducer.
Referring to Fig. 2, present embodiment provides a kind of hydraulic type reverse gear lockset body structure of five speed transmission.It is by reverse gear lock pressure relief device 1, reverse gear shifting block 2(hydraulic cylinder piston) and cylinder wall 3 form.The driver firmly is that the lower end of speed change lever 4 promotes reverse gear shifting block 2 in the time of will hanging into reverse gear, and this moment, pressure transducer was just gathered pressure information.
Referring to Fig. 3, be specific operation process of the present utility model, behind the vehicle launch, pressure transducer just constantly detects the suffered pressure of reverse gear shifting block, if detect the driver intention of hanging reverse gear is arranged, then hydraulic type reverse gear lock locking be oil hydraulic cylinder pressurize and voice prompting device prompting driver this be operating as the reverse gear operation, postponing behind the certain hour is oil hydraulic cylinder release behind the hydraulic pressure pressurize certain hour.If the driver is misoperation in this process, then the driver can change operation in retard time; If driver's operation is moveed backward exactly, automobile is hung into reverse gear after retard time.
The utility model is a kind of extension reverse gear prior-warning device, prevents from that the driver from hanging reverse gear and attempt to hang reverse gear under steam and the accelerating gear wearing and tearing under the misoperation situation.
