Abstract
The utility model relates to the technical field of the motor vehicle control, in particular a locking type overrunning clutch synchronizer, comprising a gear holder 1 fixed on an output shaft 10, a gear sleeve 3 covered outside the gear holder and gears 9 and 11 covered loosely on the output shaft 10; a sliding block 2, a locating stud 4 and a spring 5 are arranged in a groove of the gear holder 1; a clutch gear holder 7 is fixed on the gears 9 and 11; a wedge block 8 is arranged inside a groove of the clutch gear holder 7; an engagement sleeve 6 is covered outside the clutch gear holder 7; the locking type overrunning clutch synchronizer has the advantages that: under the unlocking state, the locking type overrunning clutch synchronizer has the function of an overrunning clutch; the operation of a gear box can be finished only by receiving the oil in the gear shift; the oil can also be saved by virtue of the freewheeling of the vehicle travel. Under the locking state of the overrunning clutch synchronizer, the gear box returns to the normal condition.
Description
One, technical field
The utility model relates to the control field of Motor Vehicle, is specifically related to a kind of locking overdrive clutch synchronizer.
Two, technical background
In the Motor Vehicle power control system, the synchronizer that mechanical transmission adopted is essentially structures such as lockpin-type and lock ring type, and its deficiency is that during vehicle driving, gear-change operation needs certain skill.Therefore increased the driving difficulty, and its complex structure, the required synchronising torque that overcomes is big.These deficiencies are all remedied by overdrive clutch formula synchronizer.But overdrive clutch formula synchronizer is when meeting complicated road conditions, when especially Motor Vehicle meets down the wet and slippery road surface of abrupt slope or ice and snow, can't realize that engine idle brakes, and can not give full play to its function, thereby set up lockable mechanism on this basis.
Three, summary of the invention
The purpose of this utility model is to provide a kind of locking overdrive clutch synchronizer that places automobile mechanical transmission.
The utility model is achieved in that it comprises that toothholder 1 fuses by spline and output shaft 10.Toothholder 1 has some uniform chutes, is provided with slide block 2, locating stud 4 and spring 5 in the chute.Outer rim at toothholder is provided with spline tooth, and tooth cover 3 is by the outside of its inner spline housing at toothholder.Clutch toothholder 7 links into an integrated entity by spline A and gear 9 and 11, and gear 9 and 11 skies are enclosed within on the output shaft 10.Clutch toothholder 7 is provided with some uniform grooves, and voussoir 8 is set in the groove.At the clutch toothholder 7 and voussoir 8 outsides engagement cover 6 is arranged.The arranged outside of engagement cover 6 has spline, and gear 9 and 11 is provided with spline B.
The utility model also has some technical characteristicss like this:
1, described toothholder 1 connects as one by spline and output shaft 10.
2, described toothholder 1 is provided with some uniform chutes, is provided with slide block 2, locating stud 4 and spring 5 in the chute.
3, the outer rim of described toothholder 1 is provided with spline tooth.
4, described tooth cover 3 is provided with internal spline, and is provided with three circular grooves in the internal spline side.
5, described gear 9 and 11 is that sky is enclosed within on the output shaft 10.Gear 9 and 11 is provided with spline A and B.
6, described clutch toothholder 7 links into an integrated entity with it by the spline A of gear 9 and 11.
7, described clutch toothholder 7 is provided with uniform some grooves, is provided with voussoir 8 in the groove.
8, described engagement cover 6 is enclosed within the outside of clutch toothholder 7 and voussoir 8.The outer rim of engagement cover is provided with spline tooth.
The utility model can be arranged on any gear that advances of mechanical transmission, at the tooth cover during to the front slide certain distance, tooth cover 3 is meshed with engagement cover 6, this moment, free wheel device was in running order, tooth cover 3 is again to the front slide certain distance in the case, tooth cover is meshed with spline B on the gear 9 again, and at this moment overrunning clutch is in lockup state, loses its overdrive clutch function.
The beneficial effects of the utility model are: locking overdrive clutch synchronizer, be in when putting into gear state, and under engine idle, Motor Vehicle can realize that idling slides, fuel saving reduces relevant component wear.When locking overdrive clutch synchronizer was in lockup state, Motor Vehicle can be given full play to the effect of engine idle braking on following abrupt slope or when travelling on the wet and slippery road surface of ice and snow, play and slow down the speed of a motor vehicle, guarantees to exercise the effect of safety.
Four, description of drawings
Accompanying drawing 1 is the structural representation of the utility model locking overdrive clutch synchronizer.
Accompanying drawing 2 is the view of putting into gear of the utility model locking overdrive clutch synchronizer.
Accompanying drawing 3 is the lockup state schematic representation of the utility model locking overdrive clutch synchronizer.
Five, specific embodiments
Below in conjunction with accompanying drawing realization the utility model is described in further detail:
In conjunction with Fig. 1, the utility model comprises that toothholder 1 links into an integrated entity by spline and output shaft 10, and some uniform chutes are set on toothholder 1, is provided with slide block 2, locating stud 4 and spring 5 in the chute.Outer rim at toothholder 1 is provided with spline tooth, and tooth cover 3 matches with the external splines of its internal spline with toothholder 1, and is enclosed within the outside of toothholder.On the tooth cover 3 three circular grooves are set, in order to put into gear or locking after the position of fixing tooth cover, prevent off-gear.Gear 9 and 11 skies are enclosed within on the output shaft 10.Clutch toothholder 7 fuses by spline A and gear 9.Clutch toothholder 7 is provided with some uniform grooves, is provided with voussoir 8 in the groove.Be with engagement cover 6 in the outside of clutch toothholder 7 and voussoir 8.The outer rim of engagement cover 6 is provided with spline tooth.Also be provided with spline B on the gear 9 and 11, tooth cover 3 can slide on spline B.
In conjunction with Fig. 2, when the tooth cover realization overdrive clutch function when spline tooth on the engagement cover 6 is meshed of sliding left.
In conjunction with Fig. 3, when the position of tooth cover 3 on Fig. 2 basis slided when spline tooth B on the gear 9 is meshed the locking of realization overrunning clutch more left.
