Abstract

The invention discloses a synchronous conical hub, which comprises a synchronous conical hub body (1). The outer conical surface of the synchronous conical hub body (1) is drilled with an oil discharging hole (2), the inner hole of the synchronous conical hub body (1) is provided with an oil storage ring (3), the oil storage ring (3) is arranged at an axial position which the inner hole of the synchronous conical hub body (1) is corresponding to the outer conical surface, one end of the oil storage ring (3) is communicated with the oil discharging hole (2), and the other end of the oil storage ring (3) is communicated with a transmission case. Since the outer conical surface of the synchronous conical hub is drilled with the oil discharging hole, and the oil storage ring is arranged on the inner hole, lubricating oil on the surface of the synchronous conical hub can be discharged rapidly when the two conical surfaces of the synchronous conical hub and a synchronous toothed ring are jointed during gear shifting, the frictional force between the two conical surfaces can be ensured, and the gear shifting time can be shortened.

Description

A kind of synchronous awl hub
Technical field
The present invention relates to a kind of synchronous awl hub.
Technical background
Automobile synchronizer is the critical component of mechanical type gear-driving speed-variable device; Use the synchronizer shift light and flexible, gear, axle are not hit during gear shift, prolong the speed changer life-span; Reduce labor intensity; Improving the power character and the fuel economy of automobile, bore the effect that hub is born gear shift, transmitting torque synchronously, is crucial, easily damaged parts in the gearbox.
Summary of the invention
The invention provides a kind of synchronous awl hub, this male cone (strobilus masculinus) of boring hub synchronously is drilled with oil drainage hole, and bore design oil storage ring is discharged surperficial lubricant oil rapidly when the awl hub engages with synchronizing tooth ring two conical surfaces synchronously during gear shift, guarantees the frictional force of two conical surfaces, shortens shift time.
The present invention has adopted following technological scheme: a kind of synchronous awl hub; Comprise synchronous awl hub body; On the male cone (strobilus masculinus) of boring the hub body synchronously, be drilled with oil drainage hole, be provided with the oil storage ring at the endoporus place of synchronous awl hub body, said oil storage ring is positioned at the endoporus axial position relative with male cone (strobilus masculinus) of synchronous awl hub body; One end of oil storage ring is communicated with oil drainage hole, and the other end is communicated with gearbox.
The male cone (strobilus masculinus) of said synchronous awl hub body is provided with two groups of oil drainage holes, three every group; Two groups of oil drainage holes are along circumference 90 degree that stagger; Said oil storage ring is annular oil storage ring.
The present invention has following beneficial effect: male cone (strobilus masculinus) of the present invention is drilled with oil drainage hole, and bore design oil storage ring is discharged surperficial lubricant oil rapidly when the awl hub engages with synchronizing tooth ring two conical surfaces synchronously during gear shift, guarantees the frictional force of two conical surfaces, shortens shift time.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is a plan view of the present invention.
Embodiment
In Fig. 1 and Fig. 2, the invention discloses a kind of synchronous awl hub, comprise synchronous awl hub body 1; On the male cone (strobilus masculinus) of boring hub body 1 synchronously, be drilled with oil drainage hole 2; Endoporus place at synchronous awl hub body 1 is provided with oil storage ring 3, and said oil storage ring 3 is annular oil storage ring, and said oil storage ring 3 is positioned at the endoporus axial position relative with male cone (strobilus masculinus) of synchronous awl hub body 1; One end of oil storage ring 3 is communicated with oil drainage hole 2, and the other end is communicated with gearbox; The male cone (strobilus masculinus) of said synchronous awl hub body 1 is provided with two groups of oil drainage holes 2, three every group; Two groups of oil drainage holes 3 are along circumference 90 degree that stagger.During gear shift synchronously the awl hub when conical ring two conical surfaces engage synchronously, the discharging through oil drainage hole rapidly of lubricant oil between the conical surface, and process oil storage ring 3 is back to gearbox, increases the friction torque of two conical surfaces, shortening shift time.
