Abstract
The utility model discloses a device for reducing bump of synchronizer toothed ring. The device includes a synchronizer hub (1), a synchronizer toothed ring (2), a synchronizer toothed sleeve (4) installed on the synchronizer hub via matching with a spline, a sliding block (6) installed in a sliding groove of the synchronizer hub (1) and the synchronizer toothed ring (2), and is characterized in that a dished spring (3) spaced from and fitted with the synchronizer toothed ring (2). The utility model can reduce dump between the synchronizer hub and the synchronizer toothed ring and noise when motion trajectory of synchronizer toothed ring is changed during gear shifting and shaking of vehicle, and has the simple structure.
Description
Technical field
The utility model relates to automotive transmission, the particularly a kind of bump of synchromesh gear hub and synchro converter ring and device of noise of reducing.
Background technique
Automobile during speed change, is to drive shift fork by driver's operating handle in running, shift fork is stirred synchronizer gear sleeve, makes synchro converter ring displacement or return, realizes the speed change conversion.Because synchronizer gear sleeve is installed on the synchromesh gear hub by spline, so synchronizer gear sleeve has identical rotating speed with synchromesh gear hub.Synchronizer gear sleeve moves axially, thereby its internal tooth is connected transferring power by slide block with synchro converter ring, and synchro converter ring speed is equated with synchronizer gear sleeve and gear speed.In synchronizer gear sleeve and gear engagement process, the axial thrust load of engagement place promotes synchro converter ring and axially moves to the gear direction, the conical surface of synchro converter ring contacts with the conical surface of driving gear, effect by frictional force, the speed of driving gear moves closer to the speed of synchro converter ring, because the oil film on the conical surface has good damping effect, so the vibration and the noise that produce are very little.Synchronizer gear sleeve continues to move vertically, and meshes with driving gear, and synchromesh gear hub, synchronizer gear sleeve reach consistent with the driving gear rotating speed at this moment, have realized the conversion of speed change.But synchro converter ring will move to the synchromesh gear hub direction when having following two kinds of situations to occur: synchro converter ring return during (1) gear shift; When (2) this gear is not worked, because automobile vibration changes the movement locus of synchro converter ring.Synchro converter ring will directly clash into synchromesh gear hub, produce big noise, produce synchro converter ring simultaneously because of the hidden danger that bump breaks, and influence the travelling comfort of car load.
Summary of the invention
The purpose of this utility model provides a kind of device that is used to reduce the synchro converter ring bump, it can be in the process of car gear shifting and automobile vibration when changing existing synchro movement locus, reduce the bump and the noise of synchromesh gear hub and synchro converter ring, and simple in structure.
The purpose of this utility model is to realize like this, synchromesh gear hub is installed on the main shaft by spline fitted, synchronizer gear sleeve is installed on the synchromesh gear hub by spline fitted, driving gear is installed on the main shaft, the synchro converter ring Spielpassung is on gear, slide block is installed in the slide block slot of synchro converter ring and synchromesh gear hub, and the dish spring axially is compressed the ground Spielpassung on synchro converter ring.
Owing to adopted technical solutions of the utility model, the dish spring is installed on the synchro converter ring, absorbs the energy that synchro converter ring clashes into synchromesh gear hub, reduce noise therefrom with the dish spring, simultaneously can also eliminate the hidden danger that synchro converter ring breaks because of bump, improve the life-span of synchro converter ring.Up to the present, by Chang'an company produced 500,000 installed the utility model structure speed changer, use the phenomenon that does not have a routine synchro converter ring to break through the user, the big reduction of noise obtains user's approval and welcome.
The utility model is simple in structure, and good damping result and cost are low.
Description of drawings
Fig. 1 is a structure diagram of the present utility model;
Fig. 2 is a kind of embodiment of the present utility model.
1 is synchromesh gear hub among the figure, and 2 is synchro converter ring, and 3 is the dish spring, and 4 is synchronizer gear sleeve, and 5 is driving gear.6 is slide block.
Specific embodiment
Referring to Fig. 1 and Fig. 2, synchromesh gear hub 1 is installed on the main shaft by spline fitted, and synchronizer gear sleeve 4 is installed on the synchromesh gear hub 1 by spline fitted, makes synchronizer gear sleeve 4 maintain identical rotating speed with synchromesh gear hub 1 when working.Driving gear 5 is installed on the main shaft, and synchro converter ring 2 Spielpassung are on gear, and slide block 6 is installed in the slide block slot of synchro converter ring 2 and synchromesh gear hub 1.Add a dish spring 3 between each synchro converter ring and the synchronizer assembly, dish spring 3 is installed between synchro converter ring 2 and the synchromesh gear hub 1.
Described dish spring 3 is installed between synchro converter ring 2 and the synchromesh gear hub 1 by Spielpassung, the dish spring is axially contacting with synchro converter ring with synchromesh gear hub respectively and suitable decrement is being arranged, the decrement of present embodiment is 0.5 millimeter, be that the dish spring all is in compressive state always when work, the power that produces is pushed synchro converter ring to the gear conical surface, the vibration that automobile produces in the process of moving causes that synchro converter ring is when the synchromesh gear hub direction is moved, the dish spring just absorbs the energy of synchro converter ring motion, stop synchro converter ring bump synchromesh gear hub, can reduce noise and eliminate the hidden danger that synchro converter ring breaks because of bump.
The dish spring of present embodiment adopts the 65Mn steel band, and thickness is 0.5 millimeter, and width is 1.8 millimeter.The diameter of dish spring is provided with according to the synchro converter ring diameter, and the diameter of dish spring is bigger than the diameter of synchro converter ring usually, to guarantee that the gap between them is 0.5 millimeter.
Synchro converter ring and dish spring adopt the ring of hollow.
The driver is in the operation speed-change process, synchro converter ring 2 displacements or return and automobile vibration have changed the movement locus of synchro converter ring 2, when synchro converter ring 2 when synchromesh gear hub 1 moves, the dish spring absorbs the energy of synchro converter ring motion, stops synchro converter ring bump synchromesh gear hub.
Claims (2)
1. one kind is used to reduce the device that synchro converter ring clashes into, comprise synchromesh gear hub (1) and synchro converter ring (2), synchronizer gear sleeve (4) is installed on the synchromesh gear hub by spline fitted, slide block (6) is installed in the slide block slot of synchromesh gear hub (1) and synchro converter ring (2), it is characterized in that dish spring (3) Spielpassung is on synchro converter ring (2).
