Chinese patent literature CN203404274, open (bulletin) day 2014.01.22, the reverse gear Toothless synchronizing ring and the speed changer thereof that disclose a kind of automotive transmission technical field are switched a grade synchronizer, the cone structure that the interior ring setting of this synchronizing ring matches with reverse gear tooth assembly, the position structure that outer shroud setting matches with reversing-gear synchronizer assembly.But this technology is at neutral gear or while hanging into other gears, and the axial and circumferential of synchronizing ring and tooth hub all exist and freely clash into the abnormal sound producing.
Model utility content
The utility model, for prior art above shortcomings, proposes a kind of slide-block mechanism of eliminating synchronizing ring and tooth hub abnormal sound, can reduce synchronizing ring and synchromesh gear hub and freely clash into the Abnormal Sound producing.
The utility model is achieved through the following technical solutions:
The utility model relates to a kind of slide-block mechanism of eliminating synchronizing ring and tooth hub abnormal sound, comprising: housing, inside casing, fixing part and steel ball, wherein: the outer peripheral bilateral symmetry of inside casing arranges housing, and bottom arranges fixing part, and the central position at top arranges steel ball; Fixing part is arranged in the die cavity of synchromesh gear hub, and two inner side ends of this die cavity offset with the exterior edge face, both sides of housing respectively, and the two ends of housing are longer than the edge of inside casing and are matched with the protruding key of synchronizing ring as two place's groove structures.
The outer peripheral both sides of described inside casing have draw-in groove, and housing is the rectangular structure of a pair of rectangle being connected with draw-in groove respectively.
The bottom of described inside casing is rectangular structure, and bottom surface and the fixing part of this rectangular structure are structure as a whole; Top is two parallel and spaced tooth-shape structures, and the centre of two tooth-shape structures arranges steel ball.
The structure of described fixing part is rectangular structure.
Between the protruding key of described groove structure and synchronizing ring, there is the gap of 1/2 tooth.
The utility model relates to a kind of synchronizer that comprises above-mentioned slide-block mechanism, comprising: Tong Bu Qi Chi Grains, synchronizing ring and slide-block mechanism, wherein: slide-block mechanism is arranged in the die cavity of Tong Bu Qi Chi Grains, and the protruding key of synchronizing ring matches with the groove structure of slide-block mechanism.
Described synchronizing ring and the axial clearance of slide-block mechanism are less than the axial clearance of synchronizing ring and synchromesh gear hub.
Described same step device tooth Grains upwards has 3 die cavities a week, in each die cavity, is respectively equipped with slide-block mechanism.
Described synchronizing ring is connected with the end face of Tong Bu Qi Chi Grains.
Slide block structure of the present utility model has avoided synchronizing ring circumferentially to contact with tooth hub, by requiring synchronizing ring and space of slider to be less than synchronizing ring and tooth hub gap, having avoided being synchronized with tooth hub axially contacts, when making automobile at neutral gear or hanging into other gears, the protruding key of synchronizing ring only can freely clash into slide-block mechanism, is isolated and eliminated the Abnormal Sound of synchronizing ring and synchromesh gear hub shock by slide-block mechanism.
