Abstract
The invention discloses a shifting-yoke-plate-type synchronizer sliding sleeve gear. The synchronizer sliding sleeve gear is characterized in that a sliding sleeve gear (1) is of a round symmetrical structure, the plate edge of the sliding sleeve gear (1) is not provided with a shifting yoke groove (2), and the shifting yoke of a transmission can be directly inserted into the plate of the sliding sleeve gear (1). The shifting-yoke-plate-type synchronizer sliding sleeve gear provided by the invention has the advantages that a shifting yoke plate structure sliding sleeve gear is adopted, thus the synchronization performance is good, the weight is reduced by about 1/4, the material is saved, the manufacture is easy and energy-saving.
Description
Technical field
The present invention relates to the board-like synchronizer sliding gear collar of a kind of shift fork.
Background technique
Sliding gear collar structure at present traditional pin-type synchronizer assembly all is the slot type structure, its shortcoming is that the weight of sliding gear collar is heavier, rotary inertia is bigger, net synchronization capability is not ideal enough, because the quality of sliding gear collar is bigger, rotary inertia is also big, and is bigger to the impact force of lock pin, lock pin ruptures easily, and synchronizer was lost efficacy.
Summary of the invention
The invention provides the board-like synchronizer sliding gear collar of a kind of shift fork, adopt the shift fork plank frame, in light weight about 1/4, save material, easy to manufacture, energy-conservation.
The present invention has adopted following scheme: the synchronizer sliding gear collar that a kind of shift fork is board-like, described sliding gear collar are circular symmetric structure, do not open fork slot on the former edge of sliding gear collar, and the shift fork of speed changer can directly insert on the former of sliding gear collar.
3 uniform lockpin holes and 3 uniform positioning pin holes are arranged on the former of described sliding gear collar; The spot-facing at described lockpin hole two ends has transition arc R.
The present invention has following beneficial effect: the sliding gear collar that the present invention adopts the shift fork plank frame is compared with the sliding gear collar of traditional shift fork slot type structural formula, and is in light weight about 1/4, saves material, easy to manufacture, energy-conservation; Lack lock in time during gear shift, little to the lock pin impact force, prolonged long service life.

Embodiment
As shown in Figure 1, the present invention is the board-like synchronizer sliding gear collar of a kind of shift fork, and sliding gear collar 1 is a circular symmetric structure, does not open fork slot 2 on the former edge of sliding gear collar 1, and the shift fork of speed changer can directly insert on the former of sliding gear collar 1; 3 uniform lockpin holes and 3 uniform positioning pin holes are arranged on the former of sliding gear collar 1; Spot-facing at the lockpin hole two ends has transition arc R.
Claims (3)
1. the synchronizer sliding gear collar that shift fork is board-like is characterized in that described sliding gear collar (1) is circular symmetric structure, does not open fork slot (2) on the former edge of sliding gear collar (1), and the shift fork of speed changer can directly insert on the former of sliding gear collar (1).
2. the synchronizer sliding gear collar that a kind of shift fork according to claim 1 is board-like is characterized in that on the former of described sliding gear collar (1) 3 uniform lockpin holes and 3 uniform positioning pin holes being arranged.
