Abstract
The utility model relates to a gear-shifting device for a speed changer of a saloon car. The gear-shifting device consists of a gear-selecting/shifting shaft, a gear-selecting return spring, a gear-shifting finger, a 1/2-gear fork entry frame, a 3/4-gear fork entry frame, a 5-reverse-gear fork entry frame, a 3/4-gear fork shaft, a 5-reverse-gear fork shaft and a 3/4-gear shifting fork which are respectively arranged in a shell body. A limiting frame with a shaft hole, a fork entry and a positioning pin is additionally arranged on the 3/4-gear fork shaft and is fixedly connected with the 3/4-gear fork shaft through the positioning pin. As the gear-shifting device is additionally provided with the limiting frame, the rotating amplitude of the 3/4-gear shifting fork is effectively limited, the radial friction between the 3/4-gear shifting fork and a synchronizer is eliminated, the noise is lowered and the service life of the gear-shifting device is prolonged.
Description
Technical field
The utility model relates to a kind of gearshift, is specifically related to a kind of saloon car transmission gearshift.
Background technique
The gear shift mechanism of traditional car manual transmission is made up of shifting operating mechanism and selector fork mechanism, and each keeps off the prong frame, shift fork is connected by pin and each retaining fork shaft.Elected shift control mechanism choose five reverse gear or one or two gears put and hang into five reverse gear or one or two the retaining a certain retaining the time, at this moment owing to there is not the location after the block selecting, refers to abut on three or the four retaining prong framves in gearshift under the effect of block selecting return spring power and make three or four retaining shift forks rotate around fork shaft.So, three or four retaining shift forks can cling on the synchronizer, cause the radial friction between the synchronizer of static shift fork and high speed rotating, bring abnormal sound and produce iron filings, influence speed changer working life.
Summary of the invention
The purpose of this utility model is the shortcoming that overcomes above-mentioned technology, and a kind of restriction three or four retaining shift fork rotation amplitudes are provided, and makes it also can not produce the saloon car transmission gearshift of radial friction with synchronizer under the effect of block selecting return spring.
Saloon car transmission gearshift of the present utility model comprise housing and be arranged on that shifting axle, block selecting return spring, gearshift in the housing refers to, one or two retaining prong framves, three or four retaining prong framves, five reverse gear the prong frame, three or four retaining fork shafts, five reverse gear fork shaft, three or four retaining shift forks, it is characterized in that: have additional position-limited rack on described three or the four retaining fork shafts; Described position-limited rack is provided with axis hole, fork and locating stud, by the locating stud on the axis hole position-limited rack and three or four retaining fork shafts is solidly connected.
The fork port and five of the described position-limited rack fork shaft that reverses gear flexibly connects.
Saloon car transmission gearshift of the present utility model has been set up position-limited rack, effectively limits the rotation amplitude of three or four retaining shift forks, eliminates the radial friction of three or four retaining shift forks and synchronizer, has reduced noise, has prolonged the working life of gearbox shifting device.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of position-limited rack 11.
Among the figure 1, shift control mechanism, 2, the shifting axle, 3, the fork, 4, gearshift refers to, 5, one or two retaining prong framves, 6,34 retaining prong framves, 7, the five prong frame that reverses gear, 8,34 retaining fork shafts, 9, five fork shafts that reverse gear, 10, block selecting return spring, 11, position-limited rack, 12,34 retaining shift forks, 13, housing, 14, locating stud, 15, axis hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1: shifting axle 2, block selecting return spring 10, gearshift are set in housing 13 refer to 4,1 retaining prong framves, 5,34 retaining prong framves 6, five prong frame 7,34 retaining fork shafts 8, five fork shaft 9, the 34 retaining shift forks 12 that reverse gear that reverse gear.On three or four retaining fork shafts 8, have additional position-limited rack 11.As shown in Figure 2, position-limited rack 11 is provided with axis hole 15, fork 3 and locating stud 14.By the locating stud on the axis hole 15 14 position-limited rack 11 and three or four retaining fork shafts 8 are solidly connected, fork shaft 9 flexible connections of reversing gear of fork 3 ports and five of position-limited rack 11.
The utility model saloon car transmission gearshift is work like this, shifting axle 2 moves along axial direction during block selecting, block selecting return spring 10 is compressed when shifting axle 2 moves upward, gearshift refers to that 4 follow shifting axle 2 and move to one or two retaining prong framves, 5 positions, this moment gearshift refers to that 4 rotates around axial direction, stirs one or two and keeps off prong framves 5 and put into gear.Block selecting return spring 10 is compressed, the reaction force of its spring acts on gearshift by shifting axle 2 and refers on 4, gearshift refers to 4 by on three or the four retaining prong framves 6 it is rotated around three or four retaining fork shafts 8, position-limited rack 11 limits the rotation amplitude of three or four retaining fork shafts 8 by five locking actions that reverse gear fork shaft 9, because three or four retaining fork shafts 8 and three or four retaining shift forks 12 are fixed together, and then the rotation amplitudes of three or four retaining shift forks 12 have also been limited, thereby eliminated the friction between three or four retaining shift forks 12 and the synchronizer, reduced noise and prolonged the working life of selector fork mechanism, extension 5 reverses gear similar.
