Abstract
An automobile transmission synchronizer is used for improving smoothness of shifting gears of an automobile. The automobile transmission synchronizer comprises a jointing sleeve, a sliding block component, synchronous rings and a gear hub, wherein the jointing sleeve is installed with the gear hub through the sliding block component in a matched mode, the sliding block component comprises three sliding blocks which are evenly arranged on the periphery of the gear hub, and the synchronous rings are symmetrically arranged on the left side and the right side of the gear hub. The automobile transmission synchronizer is characterized in that each sliding block is in an integrated structure which is formed by two steel balls, and a compression spring is installed below each steel ball. The automobile transmission synchronizer is simple in structure and stable in performance, gear shifting quality of a transmission is effectively improved, a phenomenon of gear-off of the automobile in the driving process is avoided, and safety performance of the vehicle is improved.
Description
Technical field
The utility model relates to a kind of synchronizer of automobile transmission, and especially a kind of have a gearshift synchronizer that prevents function out of supply, belongs to the vehicle transmission gear technical field.
Background technique
Smooth-going rapidly for guaranteeing the automobile gear shift process, on automotive transmission, all configured synchronizer.Synchronizer generally is comprised of clutch collar, slide block, synchronizing ring and tooth hub, as shown in Figure 1, existing synchronizer structure feature is: slide block is the integral type structure, below installing one in the middle of the slide block with spring-supported steel ball, the spline that clutch collar cooperates with slide block is provided with a groove, under the neutral state, steel ball is in the groove; During gear shift, clutch collar is crossed slide block and is engaged with the soldered tooth of target shifting gear, realizes synchronously.There is the defective of two aspects in the synchronizer of this kind structure, and the one, clutch collar crosses behind the slide block that spring is in compressive state below the steel ball, so clutch collar bears the spring thrust that is transmitted by steel ball, affects property of automatic shft; The 2nd, after synchronizing process was finished, the synchronizer key place lacked the anticreep mark structure, had risk out of supply in the Vehicle Driving Cycle process.
The model utility content
The purpose of this utility model is the drawback for prior art, a kind of simple in structure, stable performance is provided, can promotes shift quality, avoids the synchronizer of automobile transmission that phenomenon out of supply occurs in the Vehicle Driving Cycle process.
Problem described in the utility model realizes with following technical proposals:
A kind of synchronizer of automobile transmission, it comprises clutch collar, slide block assembly, synchronizing ring and tooth hub, described clutch collar is equipped by slide block assembly and tooth hub, described slide block assembly comprises three slide blocks that are evenly arranged along tooth hub outer rim, described synchronizing ring is arranged symmetrically in the tooth hub left and right sides, its specialization is: described slide block is two steel ball integral structures, below two steel balls Compress Spring is installed respectively.
Above-mentioned synchronizer of automobile transmission, described clutch collar madial wall spline tooth is provided with positioning boss, described positioning boss and slide block coupling, under the neutral position state, positioning boss is positioned at the centre of slide block two steel balls.
Above-mentioned synchronizer of automobile transmission, described positioning boss are positioned at a side of slide block steel ball after slide piece finishes.
The utility model can be finished the synchronizing process of clutch collar and target gear gear engagement tooth when shifting of transmission, in clutch collar and target gear gear engagement indented joint, effect by sliding block spring power, the positioning boss inclined-plane of steel ball and combined cover madial wall produces a power that promotes clutch collar, this power can increase gear shift and suck sense, promotes property of automatic shft; The utility model is after the engaging process of clutch collar and target gear engagement tooth is finished, and sliding block spring becomes free state by compressive state, can prevent the disengagement of clutch collar and target gear engagement tooth.In a word, the utility model is simple in structure, stable performance, effectively promoted the shift quality of speed changer, has avoided vehicle that phenomenon out of supply occurs in the process of moving, has improved the Safety performance of vehicle.

Embodiment
Referring to Fig. 1, Fig. 2, Fig. 3, Fig. 4, the utility model comprises clutch collar 1, slide block assembly, synchronizing ring 4 and tooth hub 2, described clutch collar 1 is equipped by slide block assembly and tooth hub 2, described slide block assembly comprises three slide blocks 3 that are evenly arranged along tooth hub outer rim, described synchronizing ring 4 is arranged symmetrically in tooth hub 2 left and right sides, its specialization is: described slide block 3 is two steel ball integral structures, below two steel ball 3-1 Compress Spring 3-2 is installed respectively.
Referring to Fig. 2, Fig. 3, the madial wall spline tooth 1-2 of clutch collar 1 of the present utility model is provided with positioning boss 1-1, described positioning boss 1-1 and slide block 3 couplings, and under the neutral position state, positioning boss 1-1 is positioned at the centre of slide block two steel balls.
Referring to Fig. 2, Fig. 3, positioning boss 1-1 of the present utility model is positioned at the side of slide block steel ball 3-1 after gearshift finishes.
Referring to Fig. 1～Fig. 9, working principle of the present utility model is: described synchronizer of automobile transmission, and when engage a gear, stir clutch collar 1 and be with movable slider 3 mobile together with shift fork.When the end contact of slide block 3 end faces and synchronizing ring boss 4-2, just promote synchronizing ring 4 and press to target shifting gear 5, synchronizing ring inner conical surface 4-1 and target shifting gear male cone (strobilus masculinus) 5-1 are fitted, because two conical surfaces have speed discrepancy, so produce frictional force once contact.Then, target shifting gear 5 drives synchronizing ring 4 by frictional force and turns in advance an angle with respect to clutch collar 1, until synchronizing ring boss 4-2 and the slide block of tooth hub 2 assemble the another side of breach when contacting, synchronizing ring 4 is just rotated synchronously with clutch collar 1.At this moment, the spline tooth 1-2 of clutch collar 1 and the synchronizing ring soldered tooth 4-3 approximately distance of half facewidth that staggered, thus the end relief face of clutch collar 1 and synchronizing ring 4 corresponding end relief faces are just in time contradicted each other and engagement can not be entered.Behind synchronizing ring 4 and target gear gear synchronous, friction torque disappears, under the ring moment loading, synchronizing ring 4 angle that is struck, synchronizing ring boss 4-2 just in time is in the centre of tooth hub 2 slide blocks assembling breach, then clutch collar 1 is crossed slide block 3, realizes smooth engage a gear, and the steel ball 3-1 of slide block 3 one sides can make gearshift increase under the effect of Compress Spring 3-2 elastic force and suck sense in this process.After gearshift finishes, slide block 3 one side steel ball 3-1 withstand the inclined-plane of clutch collar 1 positioning boss 1-1 under the effect of Compress Spring 3-2 elastic force, this power can play clutch collar 1 and prevent the unexpected effect that breaks away from gear combining tooth, can prevent that namely the speed changer accident is out of supply when driving.
