Principle of the present utility model and working procedure:
The purpose of this utility model is to provide a kind of scope shift transmission display means for gear-location with prompt facility.This gear has gear demonstration, racing of the engine protection, the functions such as auxiliary box synchronizer protection, the prompting of lifting gear and memory storage speed changer Operational Limits.
The scope shift transmission of 12 gear 2 * 6 structures of take is example, and the technical solution of this model utility is described.
On speed changer, fill two Hall revolution speed transducers, measure respectively transmission output speed n
outwith main tank jack shaft 6 gear gear rotational speed n
6.In the time of the complete combination of clutch, by n
6by certain conversion, just can obtain engine speed n
e.As Fig. 2, in the lower end of compartment shift handle, arrange 7 touch switch (S
1, S
2, S
3, S
4, S
5, S
6, S
7), by adjusting the position of switch, guaranteeing, when handle gearshift puts in place, has and only has the state of a switch in opening.A touch switch S is also installed in handle high to low gear diverter switch
8, when handle high to low gear diverter switch is during in high gear position, S
7state in opening.In the time of neutral, S
1～S
7states in closing all.So such 8 gears that touch switch just can be identified.By Experimental Calibration, go out to be not suitable for to change to the output shaft rotating speed of the speed changer in low gear district.Work as n
outwhile being greater than this demarcation speed, indication when red, if represent that now changing to low gear district likely damages auxiliary box synchronizer; Green light represents safety.In controller, have EEPROM storage unit, can record the speed of a motor vehicle that changes to each time low gear district, this can provide test data for the research of synchronizer.The red led for racing of the engine protection on display floater, when red represents now to change to this gear can cause racing of the engine.There are one-parameter power character and Economy schedule in controller inside.3 gearshift model selection buttons on the right side of panel shown in Fig. 3, represent respectively power character and Economy and cancellation pattern.Press corresponding button, gear demonstration side "+,-", will point out and add, subtract gear according to corresponding rule.When having red light prompting, driver is faulty operation still, will cause buzzer warning in addition.When driver changes to low gear district irrelevantly, buzzer can and continue with " drip～drip～" 1 second, sound interval to report to the police for 10 seconds.During racing of the engine, buzzer can be reported to the police with " dichloro-diphenyl-dichlorothane～dichloro-diphenyl-dichlorothane～" interval for 1 second, until engine speed recovers normal.After controller powers on, whether detect speed changer in neutral, if not in neutral, buzzer can with " dichloro-diphenyl-dichlorothane drip ", continuously every warning, prompting driver speed changer be in neutral, until driver changes to neutral by speed changer, buzzer is stop alarm.
Gear level place integrated gear monitoring device device, this just can be by gear level position judgment gear.Simultaneously can be according to gearshift mode annunciations plus-minus gear.In the time of may causing racing of the engine when putting into gear, device is by acousto-optic hint driver.When the speed of a motor vehicle is not suitable for Gua Ru low gear district, device can be pointed out driver by warning light.
Gear on-off is in conjunction with gear level position judgment gear.This device can be according to institute's shifting mode annunciations plus-minus gear simultaneously.In the time of may causing racing of the engine when putting into gear, device is by acousto-optic hint driver.When the speed of a motor vehicle is not suitable for Gua Ru low gear district, device can be pointed out driver by warning light.
Above content is only explanation technological thought of the present utility model; can not limit protection domain of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technological scheme basis, within all falling into the protection domain of the utility model claims.
