Description
Technical field
The utility model relates to a kind of change-speed box, and particularly a kind of automobile is used change-speed box.
Background technology
At present, a lot of drivers are when carrying out descending, in order to save oil plant; Be shelved on the position of neutral to gear, can save oil plant, because during neutral though do like this; Driving engine does not carry out work, and the air pressure pump that be provided with on the driving engine this moment can't be given the storage tank air feed, in case the high pressure gas in the storage tank use up; High pressure gas used when braking just can't be provided, cause automobile to brake at last, cause safety misadventure.
The utility model content
The purpose of the utility model a kind ofly can be used change-speed box at the automobile of the neutral time control speed of a motor vehicle with regard to providing.
The purpose of the utility model is to realize through such technical scheme; A kind of automobile is used change-speed box, comprises main gearbox, and it also comprises demultiplicator and Air compressor; Said demultiplicator comprise output shaft, input shaft and be arranged on output shaft and input shaft on two the retaining speed-changing mechanisms; One end of said output shaft is connected with the main shaft of main gearbox, and the other end is connected with the main shaft of Air compressor through power-transfer clutch, and an end of said input shaft is connected with the transmission shaft of automobile.
Further, said demultiplicator comprises casing, and said output shaft and input shaft all are arranged in the casing, the said declutch shift shaft that in casing, also is provided with, said transmission I and the driving cog II that on output shaft and input shaft, is respectively arranged with to the constant-mesh state; Said two retaining speed-changing mechanisms comprise the shift fork tooth that is arranged on the output shaft, are arranged on the shift fork on the declutch shift shaft and are arranged on the retaining of one on input shaft driving tooth, two retaining driving tooths that said shift fork and shift fork tooth are the constant-mesh shape.
In the utility model, need prolong the stroke of brake pedal at first during fabrication, simultaneously, the pneumatic line of brake pedal is connected with shift fork, and Air compressor is connected with storage tank.
The utility model is work like this: when automotive operation arrives descending, step on the brake pedal of automobile, gear is allocated to neutral; Step on brake pedal simultaneously, brake pedal is stepped on to 1/4th places, the pneumatic line of brake pedal promotes shift fork; Shift fork drives the left gear and a retaining driving tooth engagement of shift fork tooth, under the effect of power-transfer clutch, output shaft is combined with the main shaft of Air compressor; At this moment, the transmission shaft of automobile drives input shaft and rotates, and the rotation of input shaft drives a retaining driving tooth and rotates; The rotation of one retaining driving tooth drives the shift fork tooth and rotates, and the rotation of shift fork tooth drives output shaft and rotates, and the main shaft that the rotation of output shaft drives Air compressor rotates; So just drive the Air compressor acting, after the Air compressor acting air is changed into high pressure gas, pass in the storage tank then.Simultaneously, the resistance that is produced during the Air compressor acting also passes to the transmission shaft of automobile successively through output shaft, shift fork tooth, a retaining driving tooth, input shaft, the rotating speed of transmission shaft is slowed down, and has so just reached the purpose of the control speed of a motor vehicle.
When the speed of a motor vehicle when a retaining is too fast, can continue to step on brake pedal, brake pedal is stepped on to 1/2nd places, make the right gear and the two retaining driving tooth engagements of shift fork tooth,, make resistance bigger, further control the speed of a motor vehicle through improving the rotating speed of Air compressor.
When needs stop, continue to step on brake pedal, the brake system of automobile is started working, parking that so just can be steady, safe.
When not stepping on brake pedal; Gear in the auxiliary gearbox is got back to neutral, and the main shaft rotation in the automobile main-gear box drives output shaft and rotates, and output shaft rotates and drives driving cog I rotation; The rotation of driving cog I drives driving cog II and rotates; The rotating band driven input shaft of driving cog II rotates, and the transmission shaft that input shaft rotates driving automobile rotates, and automobile is in the cruising state.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, simple operation, it also has following advantage simultaneously:
1. during descending, utilize the resistance of the main shaft of Air compressor to control the rotating speed of transmission shaft, reached the purpose that reduces the speed of a motor vehicle, improved the safety factor of driving.
2. during descending, driving engine is in neutral, does not carry out work, has not only saved fuel oil, but also has improved driving engine service life.
3. utilize Air compressor that storage tank is put on the air, reduced the air pressure pump that is provided with on the driving engine, practiced thrift cost, also practiced thrift engine power.
4. pass through the resistance control speed of a motor vehicle of the main shaft of Air compressor, reduced the number of times of brake, prolonged the service life of brake facing;
5. but the high pressure gas supply engine starter motor in the storage tank starts driving engine.
Description of drawings
