Abstract
The utility model relates to a combined type synchronizer, pertaining to the technical field of the variable speed control of a motor vehicle, comprising a change gear device, an overrunning clutch type synchronizer and a locking ring type synchronizer. The change gear device is arranged on an output shaft 9 and consists of a gear holder 1, a sliding block 2, a gear sleeve 3, a positioning lock 4, and a spring 5; the overrunning clutch type synchronizer consists of a high-speed gear 8, an engagement sleeve 6, a wedge block 10 and a clutch gear holder 7; the locking ring type synchronizer consists of a low-speed gear 13, a synchronous cone 12 and a synchronous gear ring 11. When an overrunning clutch is in a high gear, the gear can be shifted easily and feely only by receiving the oil without stepping on the clutch; and the inertia of the vehicle travel also can be utilized to receive the oil so as to cause an engine to slide under the idle speed, thereby realizing the function of saving fuel, and reducing the relevant wearing and tearing of the engine; when the vehicle encounters with an abrupt slope or a wet and slippery road surface, a gear engagement state of the locking ring type synchronizer can be changed into at any time.

The purpose of this utility model is to provide a kind of combined type synchromesh gear of speed changer under each gear that place for Motor Vehicle.
The utility model is achieved in that gearshift comprises toothholder 1, slide block 2, tooth cover 3, locating stud 4 springs 5, output shaft 9, toothholder places on the output shaft, with spline the two is connected as one the be placed in both sides overdrive clutch formula synchronizer of gearshift of overdrive clutch formula synchronizer and lock ring type synchronizer and comprises: high speed gear 8, clutch toothholder 7, voussoir 10, engagement cover 6; The lock ring type synchronizer comprises: bootom gear 13, synchronizing cone 12, synchronizing tooth ring 11.
The utility model also has some technical characteristicss like this:
1, described toothholder 1 is connected as a single entity by spline and output shaft 9.
2, described toothholder 1 is provided with uniform chute, and slide block 2, locating stud 4, spring 5 are housed in the chute.
3, described toothholder 1 is provided with interior external splines.
4, described high speed gear 8 skies are enclosed within on the output shaft 9, and this gear is connected as a single entity by spline and clutch toothholder 7, and the clutch toothholder is provided with some grooves, and voussoir 10 is housed in the groove.
5, described engagement cover 6 is enclosed within the outside of clutch toothholder 7 and voussoir 10, and the outer rim of engagement cover is provided with spline tooth
6, described synchronizing cone 12 connects as one by spline and bootom gear 13, and synchronizing cone is provided with outer conical surface and spline tooth.
7, described synchronizing tooth ring 11 is enclosed within on the outer conical surface of synchronizing cone by its internal conical surface sky.
8, described bootom gear 13 skies are enclosed within on the output shaft 9.
9, described high speed gear 8 can be arranged to one with input shaft.
10, the left end of described output shaft 9 can be inserted in the input shaft bore.
The beneficial effects of the utility model are: this combined type synchronizer places in the speed changer, when overdrive clutch formula synchronizer places top gear or hypervelocity gear, can give full play to the performance of overdrive clutch formula synchronizer, need not step on clutch pedal during the conversion gear, only need the light throttle of receiving, the conversion gear is easy and simple to handle quickly and easily.Can also effectively bring into play motor-driven vehicle going inertia in addition, receive oily idling and slide, thereby save fuel oil.When the locking synchromesh gear places bottom gear, when Motor Vehicle meets the wet and slippery road conditions of ice and snow, can receive oily idling, play and slow down the speed of a motor vehicle, the auxiliary braking effect.
