Abstract
The utility model discloses an input hub assembly for a gearbox. The input hub assembly is used for transmitting torsion and comprises a body, a tooth groove is arranged on the body, a positioning ring is fixed on the body, a disk matched with the tooth groove and used for transmitting torsion is sleeved at one end of the body, an elastic stopping ring is arranged between the disk and the positioning ring, the disk is located at one end of the positioning ring, and a piston is arranged at the other end of the positioning ring. The input hub assembly for the gearbox is characterized in that an annular groove is arranged on the end face of the disk facing to the elastic stopping ring, and the elastic stopping ring is embedded in the annular groove. The input hub assembly for the gearbox solves the problem of failure of the whole hub assembly caused by debris generated by breakage of the elastic stopping ring due to the fact that the elastic stopping ring is thin in structure and cracks easily because of extrusion, impact and abrasion of the piston during rising and descending in an actual using process. The input hub assembly for the gearbox has the advantages of being compact in structure, convenient to process and long in service life.

Technical field
The utility model relates to a kind of auto parts and components, especially a kind of input hub assembly for the gearbox transmitting torque.
Background technique
Input shaft in automobile gearbox generally need to transfer torque to the output hub by the input hub assembly, by exporting hub to other mechanism's output torques.Common, the input hub assembly comprises the input hub body that is set on the input shaft, body is provided with teeth groove, also be arranged with the disc that cooperates with teeth groove on the body, be installed with outstanding limited ring on the body, disc is arranged on an end of limited ring, the other end of limited ring is provided with piston, be provided with the circlip of annular between disc and the limited ring, this circlip inner ring is provided with and the rack saw of inputting the hub teeth groove and cooperating, circlip is set on the input hub body, in the process of engage a gear or gearshift, arranging of this circlip can be played the effect that buffering reduces to impact, the travelling comfort of increase driver operation when gearshift, yet because elastic collar structure is thinner, in the process of input hub body along with the input shaft rotation, the rack saw of this circlip inner ring easily makes input hub body produce wearing and tearing with inputting the outer wall generation relative movement on the hub body, serious meeting makes generation one circle groove on the input hub body; And be not provided with the circlip of rack saw for inner ring, in the process that input hub body rotates along with input shaft, this circlip can with input hub body generation relative movement, the outer wall of input hub body is had dissection, Shi Erjiu it, also can produce a circle groove on the input hub body.Because the thickness of circlip differs, on the input hub body frayed and produce the width of groove also can be uneven, when circlip and input hub body generation relative movement run on the input hub body unworn rack saw, circlip meeting fracture, be splashed in the gearbox, the fragment that fracture produces or powder can stop up the valve body of control oil inlet quantity in the gearbox, and serious meeting causes whole gearbox to lose efficacy.
The model utility content
In order to overcome the deficiencies in the prior art, the utility model provides the input hub assembly of a kind of compact structure, easy to process, long service life.
To achieve these goals, the technical solution adopted in the utility model is: a kind of input hub assembly for gearbox, comprise body, body is provided with teeth groove, be installed with positioning ring on the body, body one end is arranged with the disc of the transmitting torque that cooperates with teeth groove, be provided with circlip between disc and the positioning ring, disc is positioned at an end of positioning ring, the other end of positioning ring is provided with piston, it is characterized in that: described disc is provided with circular groove towards the end face of circlip, and described circlip is embedded in circular groove.
Adopt said structure, circlip is embedded direct contact that in the circular groove of disc, can avoid circlip and input hub body, avoid the relative movement of circlip with the input hub, just can not produce wearing and tearing to input hub body, can prolong the working life of input hub assembly.
As further setting of the present utility model, the outer wall of described circular groove is provided be used to the overhead structure that prevents that circlip from jumping out.
Adopt said structure, at the outer wall of circular groove one circle barb is set and prevents effectively that circlip from jumping out and play further position-limiting action.This barb is higher than circular groove inwall, being positioned at input disc topmost not only has the effect of transmitting torque, also play simultaneously the effect of pushing down following these discs and circlip, these discs and circlip are played position-limiting action, make to have small space between piston and the circlip so that the barb of circular groove outer wall setting can prevent circlip jumps out; In addition owing to offered circular groove at the input disc, so that the strength decreased of this disc, and also have simultaneously the effect of stiffening rib at the barb of the outer wall setting of this circular groove, can strengthen its intensity, remedy and offer the intensity that the circular groove lock reduces.
As further setting of the present utility model, the groove depth of described circular groove is 1/2 of disc thickness.
Adopt said structure, can when guarantee disc strength, make circular groove have enough spaces and hold circlip.
As further setting of the present utility model, described circlip is tool C shape jaggy structure.
Adopt said structure, tool circlip jaggy uses more convenient, easier being embedded in circular groove.
As further setting of the present utility model, described disc comprises input disc and output disc, input disc and output disc are spaced distribution, and the interior ring of input disc is provided with the rack saw that cooperates with teeth groove on the body, and the outer shroud of exporting disc is provided with and the rack saw of exporting hub and cooperating.
Adopt said structure, the input disc is delivered to the output disc with the moment of torsion of input shaft output, and input disc and output disc are spaced distribution, and the transmitting torque effect is better.
As further setting of the present utility model, the described input disc end face of exporting disc that reclining is provided with friction plate.
Adopt said structure, the two ends of input disc all are provided with friction plate, because input disc and output disc are spaced, arranging of friction plate can prevent from skidding between the two.
Below in conjunction with accompanying drawing the utility model is further described.
