Description
Technical field
The utility model relates to the Automotive transmission technical field, specifically relates to a kind of manual gear of vehicle gear read out instrument.
Background technology
As everyone knows, hand-operated transmission is is mainly connected and composed by gear box, shifter bar 1, declutch shift shaft 3, the lock pin 5 that reverses gear, reverse gear lock spring 6 and the shifting block 7 that reverses gear, as shown in Figure 1, the hand-operated transmission of this structure adopts gear transmission, has several definite value transmitting ratios.Car and light, medium truck change-speed box adopts 3～5 forward gears and one to reverse gear the corresponding transmitting ratio of each gear.The function of transmission control is to guarantee that chaufeur can change to certain gear with change-speed box according to usage condition.Prevent change-speed box self shifter and automatic off-gear; Guarantee that change-speed box can not change to two gears simultaneously; Prevent that the mistake extension from reversing gear.The shifter bar of cane type shift device and other shifting operating devices all are arranged on the transmission case cover, gearbox arrangement is near operating seat, shifter bar is stretched out by the operator's compartment base plate, but the shifting operating device that chaufeur direct control shifter bar is stirred in the transmission case cover is shifted gears.Along with the increase of automobile pollution, amateurish chaufeur is also more and more, and some driving techniquies are not very skilled people, do not know to hang over which gear when running car sometimes; Bow easily during the operation that has and see shifter bar, hang which gear, hang retaining? driving is very dangerous like this, may cause traffic accident.
The utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of simple in structure, effectively improving the manual gear of vehicle gear read out instrument of driving safety.
The technical matters that the utility model proposed is to solve like this: a kind of manual gear of vehicle gear read out instrument, described read out instrument is is mainly connected and composed by gear telltale and gear switching mechanism, described gear telltale is arranged on the indoor gauge panel of vehicle drive, gear switching mechanism is fixed in the casing of change-speed box by attaching screw, gear switching mechanism also is set on the shifter bar that is positioned at change-speed box, and described gear telltale is connected with gear switching mechanism by lead.
Described gear switching mechanism mainly connects and composes by being set in box body on the shifter bar, several and the cooresponding gear contact switch of automobile shift number and gear indication electronic commutator, described box body is provided with automobile shift is corresponding and carries out the chute that gear switches in order to mobile shifter bar, and described gear contact switch is arranged at the terminal end of chute respectively; Each gear contact switch is connected with gear indication electronic commutator simultaneously by lead respectively.
Described gear switching mechanism comprises that also to be arranged at each gear contact switch other in order to order about the pull back spring that the gear contact switch resets.
In sum, the utility model is simple in structure, informs driver's gear situation timely and effectively, has improved the safety of travelling, and reduces the probability of traffic accident, ensures the safety of chaufeur.
