Abstract
The utility model pertains to the category of auto manufacture, in particular a double-mid-shaft auto governor, which comprises an input shaft, a mid shaft and a main shaft and is characterized in that the main cabinet main shaft of the double-mid-shaft auto governor is provided with a synchronizer; the integral key in the input shaft the gear is provided with a synchronous cone; the synchronizer is the single-cone lock ring inertia synchronizer composed of a synchronous ring, a spring, a synchronous pushing block, a fixed gear base and a sliding gear sleeve. The advancing shift gear and the input shaft gear on the main shaft are meshed through the integral key. The double-mid-shaft auto governor of the utility model uses the friction conical surface of the single-cone lock ring synchronizer to attain the process of synchronous shifting so as to make the shifting comfortable. The synchronizer enables the to-be-clutched gear to go in the same pace with the rotation rate of the sliding gear sleeve, so as to realize the shifting. The utility model is easy to clutch on the shit and avoids the case of two steps on the clutch and gear collision during shifting.
Description
Technical field
The utility model belongs to the automobile making class, specifically is a kind of pair of jack shaft automotive transmission.
Background technique
At present, the twin countershaft transmission that uses on the heavy-duty car, its main tank part is tape synchronizer not, the driver is in startup procedure like this, must step on the bipod clutch, during also must bang throttle one time, influence the driving travelling comfort, especially on luxurious bus, can not adopt basically.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of more reasonable structure, more reliable pair of jack shaft automotive transmission of use that has single awl lock ring type inertia synchronizer is provided.
The utility model is achieved through the following technical solutions:
A kind of pair of jack shaft automotive transmission comprises input shaft, jack shaft, main shaft, it is characterized in that: on the main tank main shaft of twin countershaft transmission synchronizer is housed, on two side gear internal splines synchronous awl is housed.
The utility model synchronizer is single awl lock ring type inertia synchronizer, it by synchronizing ring, spring, synchronously pushing block, fixedly toothholder, sliding gear collar are formed.Often mesh by spline between each forward gears gear on the described main shaft, input shaft gear and the synchronous awl.
The cone of friction of the of the present utility model pair of single awl of jack shaft automotive transmission utilization lock ring type synchronizer reaches the gear shift synchronizing process, makes gear shift comfortable; Synchronizer reaches synchronously the gear of wanting engage a gear and the rotating speed of sliding gear collar, thereby realizes gear shift.The utility model engage a gear is easy, steps on the bipod clutch when having avoided gear shift and beats the tooth phenomenon.This automotive transmission handiness, use reliable, simple in structure, be easy to manufacturing.

Embodiment
As shown in Figure 1, 2, a kind of pair of jack shaft automotive transmission, comprise input shaft 1, jack shaft 6, main shaft 3, it is characterized in that: single awl lock ring type inertia synchronizer 4 is housed on two jack shaft automotive transmission main tank main shafts 3, synchronous awl 8 is housed on two side gear internal splines; Described single awl lock ring type inertia synchronizer 4 by synchronizing ring 9, spring 10, synchronously pushing block 11, fixedly toothholder 12, sliding gear collar 14 are formed.Often mesh by spline between each forward gears gear on the described main shaft 3, input shaft gear 2 and the synchronous awl 8.
The utility model automobile power is passed on the input shaft 1 by clutch by motor, pass on the input shaft gear 2 through spline again, power passes on the jack shaft 6 through jack shaft constant mesh gear 5, and each grade gear rotates together on the drive jack shaft, and each grade gear that drives at last on the main shaft 3 rotates.In the time will hanging into second gear, handling gearshift mechanism makes shift fork 13 toward moving left, promote synchronizer sliding gear collar 14 past moving left on fixing toothholder 12, pushing block 11 is turned left mobile under spring 10 and sliding gear collar 14 effects together synchronously, pushing block 11 acts on synchronizing ring 9 synchronously, synchronizing ring 9 and synchronous awl 8 are compressed, this moment, synchronizing ring 9 was with fixedly toothholder 12 rotating speeds are identical, awl 8 is identical with intermediate gear 7 rotating speeds synchronously, have speed discrepancy between the two and produce frictional force, under the effect of frictional force, overcome inertial force after, make both rotating speeds identical, rub-moment disappears, and shift fork 13 continues toward moving left, and sliding gear collar 14 is crossed synchronizing ring 9, with synchronous awl 8 engagements, realize not having synchronously the engage a gear of impact.
Claims (3)
