Abstract
The utility model provides a connecting structure of a shifting fork of an automobile, and belongs to the technical field of automobiles. The connecting structure of the shifting fork of the automobile solves the problem of easy abrasion caused if the shifting drum is directly connected with the shifting fork in the prior art. The connecting structure of the shifting fork of the automobile comprises a shifting shaft, a shifting fork which is fixedly connected to shifting shaft, and a shifting drum which is connected with the shifting shaft and can drive the shifting shaft to move in the axial direction of the shifting shaft, wherein a pin shaft is axially fixed on the shifting shaft; a guide groove for driving the shifting shaft to move in the axial direction of the shifting shaft is formed on the peripheral wall of the shifting drum; and a bearing is sleeved on the pin shaft, and the pin shaft is connected to the guide groove through the bearing. According to the connecting structure, the bearing is movably sleeved on the pin shaft, and the pin shaft is connected to the guide groove, so that the abrasion between the shifting drum and the shifting fork can be prevented.
Description
Technical field
The utility model belongs to automobile technical field, relates to a kind of linkage structure of automobile gear shift shift fork.
Background technique
Along with advancing and rapid development of automobile industry of society, people's living standard constantly improves, and automobile has become one of a kind of important traffic tool that people ride instead of walk, and the component on the automobile are the indispensable assemblies of automobile.Manual transmission shift control mechanism on the automobile generally is made up of primary components such as operating handle, shifting block, shift fork, speed changer fork shaft and interlocking, self-locking, reverse gear lock device, dunnage assembly, guide plate assemblies; Relevance is strong between its complex structure and each control unit; A link goes wrong, with the performance that affects whole shifting system.
Existing speed changer is general to adopt a gearshift that has guard rail to rouse; This gearshift drum drives the selector fork that is connected in the guard rail and axially moves in rotary course; Make selector fork accomplish the action of changing block selecting; Traditional selector fork directly is installed in the guard rail of gearshift drum, makes it gearshift drum and selector fork easy abrasion; Also have selector fork and gearshift drum directly to cooperate, in shift process, can make the gearshift time longer, cause the car load power system to be interrupted, make vehicle in the process of quickening, acceleration is suddenly zero, serious threat acceleration person's safety.
Summary of the invention
The purpose of the utility model is to existing deficiency, and a kind of linkage structure of avoiding selector fork and gearshift to rouse the automobile gear shift shift fork that directly is slidingly connected is provided.
The purpose of the utility model can realize through following technical proposal: a kind of linkage structure of automobile gear shift shift fork; Comprise a gearshift axle and be connected in selector fork on the gearshift axle, and link with the gearshift axle and can drive the gearshift of moving along its axial direction of shifting gears spool and rouse; A radially fixing bearing pin on the gearshift axle; On the periphery wall of gearshift drum, offer and drive the guiding groove that above-mentioned gearshift axle moves along its axial direction, a sheathed bearing and be connected in the guiding groove on above-mentioned bearing pin through bearing.
The linkage structure of this automobile gear shift shift fork mainly is made up of gearshift drum and selector fork; This selector fork is fixed on that gearshift axle is gone up and drives selector fork by the gearshift axle and moves along the axial direction of gearshift axle and make it to accomplish gearshift work; This gearshift drum offers guiding groove by the driven by motor forward or reverse on the perisporium of gearshift drum, radially be fixed with bearing pin on the gearshift axle; Bearing pin is connected on the guiding groove through bearing, and this bearing pin drives the bearing pin axial motion by guiding groove.
In the linkage structure of above-mentioned automobile gear shift shift fork, described guiding groove is obliquely installed on the periphery wall of gearshift drum.This guiding groove roughly in the shape of a spiral shape be positioned on the periphery wall of gearshift drum.
In the linkage structure of above-mentioned automobile gear shift shift fork, on the perisporium of gearshift axle, radially offer an attachment hole, above-mentioned bearing pin is plugged in the attachment hole.This bearing pin interference is connected in the attachment hole.
In the linkage structure of above-mentioned automobile gear shift shift fork, described bearing fixing is connected on the bearing pin.This bearing can roll on guiding groove.
In the linkage structure of above-mentioned automobile gear shift shift fork, the diameter of said bearing outer ring equals the width of guiding groove.The race diameter of this bearing matches with the width of guiding groove.
Compared with prior art, on bearing pin, a be slidingly connected bearing and be connected in the guiding groove of the linkage structure of this automobile gear shift shift fork through bearing, wearing and tearing between drum and the selector fork like this can prevent to shift gears; Selector fork is connected through bearing with the gearshift drum, and the gearshift time shortens in shift process, can not cause the car load power system to be interrupted, and guarantees the safety that driving is quickened.
Description of drawings
Fig. 1 is the perspective view of the linkage structure of this automobile gear shift shift fork.
Among the figure, 1, gearshift axle; 2, selector fork; 3, gearshift drum; 4, bearing pin; 5, guiding groove; 6, bearing; 7, attachment hole.
Embodiment
Below be the specific embodiment of the utility model and combine accompanying drawing, the technological scheme of the utility model is done further to describe, but the utility model is not limited to these embodiments.
As shown in Figure 1, the linkage structure of this automobile gear shift shift fork mainly is made up of gearshift axle 1, selector fork 2 and gearshift drum 3, and this gearshift drum 3 is by the driven by motor forward or reverse; This selector fork 2 is fixed on the gearshift axle 1; In shifting system, should circumferentially fix, and can only axially move by gearshift axle 1, on the perisporium of gearshift axle 1, radially offer an attachment hole 7; Interference is plugged with bearing pin 4 in attachment hole 7, and fixing bearing 6 on bearing pin 4; On the periphery wall of gearshift drum 3, drive guiding groove 5; This gearshift axle 1 is connected on the guiding groove 5 through bearing 6, and the diameter of bearing 6 outer rings equals the width of guiding groove 5, both connections that match; This guiding groove 5 is roughly helical, and is obliquely installed on the periphery wall of gearshift drum 3; When motor passed through gear driven gearshift drum 3 forward or reverse, the guiding groove 5 on the gearshift drum 3 drove bearings 6 and slides with respect to guiding groove 5, and made the axle 1 of shifting gears move the gearshift work of accomplishing along its axial direction.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from the spirit of the utility model or surmount the defined scope of appended claims.
