Abstract
The utility model discloses an automobile synchronizer, which comprises a synchronous conic hub (2), a synchronous ring (3), a sliding toothed sleeve (4) and a synchronous toothed seat (5). The inner conic surface of the synchronous ring (3) is connected with the outer conic surface of the synchronous conic hub (2), the synchronous toothed seat (5) is arranged in the synchronous conic hub (2) and connected with the inner conic surface of the synchronous ring (3), and the sliding toothed sleeve (4) is arranged outside the synchronous conic hub (2) and connected with the outer conic surface of the synchronous ring (3). The sliding toothed sleeve (4) is movably connected with the synchronous toothed seat (5) through a spline, a limit plate (1) is further welded on the end face of the synchronous conic hub (2), and a grinding undercut (6) is arranged on the end face of the sliding toothed sleeve (4). By means of the automobile synchronizer, a synchronous sliding sleeve does not shed caused by skip distance when gear shift of the synchronizer is carried out, and damage to a speed changing box caused by damage or scattering of the synchronizer is avoided.
Description
Technical field
The utility model relates to a kind of automobile synchronizer.
Background technique
Automobile synchronizer is the critical component of mechanical type gear-driving speed-variable device, uses synchronizer gearshift light and flexible, and gear, axle are not hit during gearshift, prolong the speed changer life-span, reduce labor intensity, improve the power character and the fuel economy of automobile.Synchronizer is born the effect of gearshift, transmitting torque, is crucial, easily damaged parts in the gearbox.
Summary of the invention
The utility model provides a kind of synchronizer automobile, makes synchronizer when gearshift unlikely surpassed distance of synchronous sliding sleeve and comes off, and avoids synchronizer to damage or synchronizer is scattered and damages gearbox.
The utility model has adopted following technological scheme: a kind of automobile synchronizer, and it comprises synchronous awl hub, synchronizing ring, sliding gear collar, synchronous toothholder, and said synchronizing ring is positioned on the synchronous awl hub, and the inner conical surface of synchronizing ring connects with the male cone (strobilus masculinus) of boring hub synchronously; Said synchronous toothholder is positioned at synchronous awl hub and links to each other with the inner conical surface of synchronizing ring; The outside that sliding gear collar is positioned at synchronous awl hub links to each other with the male cone (strobilus masculinus) of synchronizing ring; Said sliding gear collar connects through spline is movable with synchronous toothholder, sliding gear collar move left and right vertically on synchronous toothholder during gearshift; Also be welded with limiting board at the synchronous end face of awl hub, be provided with grinding undercut at the end face of sliding gear collar, when sliding gear collar during to synchronous awl hub side shifting, limiting board and grinding undercut form spacing.
Be provided with supporting base with the synchronizing ring connecting part in the said synchronous toothholder, the bottom of said supporting base links to each other with the upper end elasticity of spring, and the bottom of spring links to each other with synchronous toothholder, is provided with roller at the top of supporting base, and roller and synchronizing ring are joined.
The utlity model has following beneficial effect: the utility model increases the gearshift restraining groove on synchronous sliding sleeve; Increase limiting board on the awl hub synchronously; Make synchronizer when gearshift unlikely surpassed distance of synchronous sliding sleeve and come off, avoid synchronizer to damage or synchronizer is scattered and damages gearbox.
