Abstract

The utility model belongs to the technical field of automobile parts, and particularly relates to a dual-mass flywheel with a plane needle roller thrust bearing. The flywheel comprises a first-level flywheel and a second-level flywheel, wherein the central shaft of the first-level flywheel and the central hole of the second-level flywheel are connected in a matching manner through a sliding bearing, and the flywheel is characterized in that the plane needle roller thrust bearing is mounted on the neck of the central shaft of the first-level flywheel in a sleeving manner; the bearing cover of the plane needle roller thrust bearing is connected with the end surface of the sliding bearing in a contacting manner. According to the utility model, the flywheel is simple in structure and ingenious in design, can improve the axial bearing capacity greatly, reduce the abrasion to the dual mass flywheels during the use, prolong the service life and improve the performance.

Description

A kind of double mass flywheel with plane needle roller thrust bearing

Technical field

The utility model relates to technical field of automobile parts, especially a kind of double mass flywheel with plane needle roller thrust bearing.

Background technique

Develop rapidly along with automobile industry, double mass flywheel is applied to more and more widely all kinds of cars and is even gently blocked, double mass flywheel is comprised of one-level flywheel and secondary flywheel, both connect by bearing, and at present double mass flywheel mainly contains two kinds of structural types: a kind of is double mass flywheel with sliding bearing structure, (referring to Fig. 1), its structure is by sliding bearing 5, to be connected between one-level flywheel central shaft 3 and secondary flywheel center hole 4, the axle journal place of one-level flywheel central shaft is set with a Sealing shield ring 7, this Sealing shield ring 7 is connected with the end contact of sliding bearing, this kind of double mass flywheel is widely used because space hold is few, but adopt the double mass flywheel of sliding bearing structure, the end that can contact with sliding bearing with Sealing shield ring 7 and Sealing shield ring 7 at the axle journal of one-level flywheel central shaft produces friction, make Sealing shield ring and bearing wear, in addition, because friction causes bearing temperature, raise, add axial pressure load, cause sliding bearing and Sealing shield ring wearing and tearing aggravation, axial pressure is larger, weares and teares more serious, finally cause bearing and Sealing shield ring early failue, fly wheel assembly cannot normally be worked, and working life is short, another kind is with the double mass flywheel of deep groove ball bearing structure (referring to Fig. 2), its structure is by deep groove ball bearing 9, to be connected between one-level flywheel central shaft 3 and secondary flywheel center hole 4, although there is not the sliding friction between bearing and flywheel in the double mass flywheel of this structure, but because deep groove ball bearing volume is large, and double mass flywheel claimed structure is compact, thereby limited its using scope.

Summary of the invention

The purpose of this utility model is exactly to exist bearing wear serious for the existing double mass flywheel with sliding bearing, working life is short, and the double mass flywheel of deep groove ball bearing is used narrow limitation larger, provide a kind of double mass flywheel with plane needle roller thrust bearing.

The technical solution of the utility model is: a kind of double mass flywheel with plane needle roller thrust bearing, comprise one-level flywheel and secondary flywheel, between described one-level flywheel central shaft and secondary flywheel center hole, by sliding bearing, be connected, particularly: on the axle journal of described one-level flywheel central shaft, be set with plane needle roller thrust bearing, the bearing cap of plane needle roller thrust bearing is connected with the end contact of sliding bearing.

Working principle of the present utility model is: when engine output torque changes, one-level flywheel and secondary flywheel just there will be relative movement, now, the needle roller of the plane needle roller thrust bearing between one-level flywheel and secondary flywheel starts to rotate, and the bearing cap of needle roller thrust bearing keeps relative static with sliding bearing end face, the end face of sliding bearing can not rub because of relative movement like this, has well reduced the wearing and tearing of sliding bearing; Simultaneously, between the bearing cap of needle roller thrust bearing and needle roller, be to adopt positive engagement, axial carrying capacity is strong, make double mass flywheel axial carrying capacity of the present utility model increase to 5500 Ns by original 2300 Ns, greatly improve the loaded capability of double mass flywheel, improved the working life of double mass flywheel simultaneously.

The utility model is simple in structure, designs ingeniously, has greatly improved the axial carrying capacity of double mass flywheel, has reduced the in use wearing and tearing of sliding bearing of double mass flywheel, has improved working life and the performance of double mass flywheel.
