Abstract
Provided are a creeper gear and a gear shift mechanism installed on the lateral face of a transmission box of a tractor. The creeper gear comprises a creeper gear cover, an auxiliary gear shaft, shifting fork heads, shifting forks, elastic pins, a clamping spring, a locating gasket, a spring, a gear shifting locating cover, a gear shifting locating pin, a gear shifting shaft, an oil seal and a gear shifting swing arm. The auxiliary gear shaft is arranged on the creeper gear cover through a taper bearing, the two shifting fork heads are arranged at the two ends of the upper portions of the shifting forks, the shifting forks are arranged on the fork shifting shaft through the elastic pins, and the clamping spring, the locating gasket, the spring, the gear shifting locating cover, the gear shifting locating pin, the oil seal and the gear shifting swing arm are sequentially arranged on the gear shifting shaft. The creeper gear and the gear shift mechanism are compact in structure and convenient to install. The auxiliary gear shaft is arranged on the creeper gear cover, and the center distance of a driving shaft and a driven shaft is changed by changing the structural size of the creeper gear cover so that matching of creeper gears of multiple speed ratios can be achieved. The gear shifting mechanism of the creeper gear is located through self-locking of a gear shifting locating lock, the locating face is the cylindrical face of the locating pin, the locating area is large, locating is more reliable, and the problem that spontaneous out-of-gear is easily caused by locating of steel balls can be effectively solved.
Description
Technical field
The utility model belongs to tractor field, relates to a kind of creeper gear and gearshift mechanism of installing from tractor transmission case side.
Background technique
At present, on the various big or middle power tractor of producing at home, its creeper gear and gearshift mechanism are installed from transmission case body is inner mostly, and its selector device is drawn from transmission case body inside, can arrange with assembling and bring larger difficulty to transmission case body like this.Meanwhile, because creeper gear structure between each type of tractor is different, component universality is poor, thereby has increased manufacture cost.Therefore be necessary to develop a kind of compact structure, the crawling gear mechanism that easy for installation, versatility is high, to meet better the usage requirement of current tractor.
Model utility content
The purpose of this utility model is to provide a kind of compact structure, creeper gear and the gearshift mechanism from tractor transmission case side, installed that easy for installation, versatility is high, to meet the usage requirement of wheeled tractor.
The technical solution of the utility model is: creeper gear and the gearshift mechanism from tractor transmission case side, installed, comprising: creeper gear lid, driven gear shaft, shift fork head, shift fork, resilient key, jump ring, space washer, spring, gear shift setting sleeve, gear shift locating stud, shift shaft, oil sealing, gear shift swing arm; Driven gear shaft is arranged on creeper gear by cone bearing and covers, two shift fork heads are arranged on shift fork both upper ends thereof, shift fork is arranged on shift shaft by resilient key, and jump ring, space washer, spring, gear shift setting sleeve, gear shift locating stud, oil sealing, gear shift swing arm are also installed on shift shaft successively from left to right.
The utility model can reach following beneficial effect after adopting technique scheme: creeper gear driven gear and gearshift mechanism are installed from gearbox casing side, compact structure, easy for installation; Driven gear shaft is arranged on creeper gear and covers, and changes main driven shaft centre distance, thereby can reach the creeper gear coupling of multiple speed ratio by changing creeper gear lid physical dimension.Creeper gear gearshift mechanism adopts the lock-bit of gear shift locating stud, and locating face is locating stud cylndrical surface, and contrast great majority adopt the gearshift mechanisms of steel ball lock-bit, and location area is large, locate more reliably, can effectively solve the easy problem out of supply in steel ball location.The utility model is subject to mechanism housing limitations affect less, arranges easy for installationly, is easy to realize the generalization between different type of machines, producing in serial form.
Accompanying drawing explanation
Fig. 1 is that the utility model is from the creeper gear of tractor transmission case side installation and the structural representation of gearshift mechanism.
Fig. 2 is that the utility model is from the creeper gear of tractor transmission case side installation and the A-A sectional view of gearshift mechanism.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figure 1 and Figure 2, creeper gear and the gearshift mechanism from tractor transmission case side, installed comprise: creeper gear lid 1, driven gear shaft 2, shift fork head 3, shift fork 4, resilient key 5, jump ring 6, space washer 7, spring 8, gear shift setting sleeve 9, gear shift locating stud 10, shift shaft 11, oil sealing 12, gear shift swing arm 13 etc.Driven gear shaft 2 is arranged on creeper gear lid 1 by cone bearing; Two shift fork heads 3 are arranged on shift fork 4 both upper ends thereof, and shift fork 4 is arranged on shift shaft 11 by resilient key 5, and jump ring 6, space washer 7, spring 8, gear shift setting sleeve 9, gear shift locating stud 10, oil sealing 12, gear shift swing arm 13 are also installed on shift shaft 11 successively.
During general assembly, first the shift shaft component being comprised of shift fork head 3, shift fork 4, resilient key 5, jump ring 6, space washer 7, spring 8, gear shift setting sleeve 9, gear shift locating stud 10 is packed into from mechanism housing side window, shift fork head 3 is inserted in the synchronizer sleeve allocating slot that in casing, driving shaft is corresponding; Again the creeper gear lid 1 that assembles driven gear shaft 2 is loaded onto, shift shaft 11 is covered 1 corresponding axis hole and stretched out from creeper gear, gear shift setting sleeve 9 sides and creeper gear are covered to 1 axis hole respective side and align, driven gear shaft 2 is cogged and corresponding gear engagement on driving shaft in casing; Oil sealing 12, gear shift swing arm 13 are finally installed.
During gear shift, gear shift setting sleeve 9 maintains static, and has two gear shift position locations of the corresponding gear shift locating stud 10 of two locating slots on it, and swing arm is forward direct high, is creeper gear backward.In gearshift procedure, gear shift locating stud 10 rotates with shift shaft 11, shift fork 4 etc., and the impacting force that overcomes spring 8 enters and another locating slot, completes gear shift, location from a locating slot of gear shift setting sleeve 9.
