The automotive wheel static release device
Technical field
The present invention relates to the automobile static release device, specifically a kind of device that discharges automobile static through automotive wheel.
Background technology
In automotive operation, multiple reason all can make automobile produce static, and the static on the automobile all has bigger harm to the operation and the driver on the car of vehicle.At present, the device that static on the automobile is eliminated mainly contains following several kinds, and a kind of is on car body, to connect conductive strips, keeps in touch with ground in vehicle ' through conductive strips, and static is discharged; Another kind is at vehicle roof static release device to be installed, and comes release electrostatic through the release antenna of this device.The shortcoming that above-mentioned dual mode exists respectively is: for the former, conductive strips in use wear and tear comparatively fast, must in time change; For the latter, need could discharge when the higher voltage at static focus, and it is higher to install self cost.
Summary of the invention
The object of the present invention is to provide a kind of automotive wheel static release device, this static release device release electrostatic effective, and long service life.
For realizing above-mentioned purpose; The present invention adopts following scheme: the automotive wheel static release device; Electrostatic conduction device and static that this device includes wheel, conduction discharge the attaching bar; Static discharge to attach bar and attaches bar and tyre bead by tyre surface and attach bar and link to each other and constitute, and tyre surface attaches in the tyre surface that bar is embedded in vehicle tyre or is embedded in the pattern groove on the tyre surface, the tire shoulder of tyre bead attaching bar and vehicle tyre and paste mutually on the sidewall and its front end is connected with the wheel hub of wheel; The top of tyre surface attaching bar is surperficial concordant with the tyre surface of vehicle tyre, and electrostatic conduction device is connected with the car body and the axletree of static electrification.
Visible by such scheme; Electrostatic conduction device can with car body with static be passed on the wheel hub of axletree and wheel; The wheel hub of wheel discharges the static that static is passed on the vehicle tyre on the attaching bar again; Through vehicle tyre and on static discharge to attach bar and contact with the earth, can static be discharged.
The present invention is rational in infrastructure, dependable performance, the effective and long service life of release electrostatic.

The specific embodiment
Further specify the present invention below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1
The static release attaching bar that automotive wheel static release device provided by the invention is had is linked to each other by tyre surface attaching bar and tyre bead attaching bar 4 and constitutes; In the present embodiment; Tyre surface attaches the connecting strap 2 that bar by vertical attaching bar 1, laterally attaches bar 3 and bending and forms; The two ends of connecting strap 2 respectively with vertical attaching bar 1, laterally attach bar 3 and be connected as one, tyre bead attaches an end of bar 4 and is connected as one with laterally attaching bar 3, discharges the inside that attaches bar at whole static and is embedded with metal filament 5.It is conductive rubber that whole static discharges the material that attaches bar.
Referring to Fig. 2
Electrostatic conduction device has roller 10, fork 9, bearing 8 and spring 7; The middle part of fork 9 and bearing 8 are hinged; Roller 10 is loaded on an end of fork 9, and bearing 8 is fixed on the car body 6 of static electrification, and the two ends of spring 7 link to each other with fork 9 and car body 6 respectively; Under the effect of the restoring force of spring 7, roller 10 and axletree 11 against.Described axletree 11 is front truck wheel shaft or rear vehicle shaft; The cooresponding many places that are arranged on of electrostatic conduction device; Be that a plurality of electrostatic conduction devices are connected the car body of static electrification respectively with a plurality of positions of each axletree, can reliably conduct on the wheel hub that reaches each wheel on each axletree through electrostatic conduction device to guarantee the static on the car body.
Referring to Fig. 3, Fig. 4
In the present embodiment; Circumferential pattern groove 12a is only arranged on the tyre surface of vehicle tyre 12; A part that vertically attaches bar 1 and connecting strap 2 is embedded among the circumferential pattern groove 12a on the tyre surface; Another part of connecting strap 2 and laterally attach bar 3 and be embedded in the tyre surface of vehicle tyre 12, tyre bead attach the tire shoulder of bar 4 and vehicle tyre 12 and paste mutually on the sidewall and its front end is connected with the wheel hub 13 of wheel, vertically attaches tyre surface surperficial concordant of horizontal attaching bar 3 top that bar 1 reaches and vehicle tyre 12.In addition, the cross-sectional plane that vertically attach bar 1, laterally attaches bar 3 is " U " font.
Referring to Fig. 4, Fig. 5
Tyre bead attaches bar 4 and can be following several kinds with wheel hub 13 ways of connecting: 1, tyre bead attaching bar 4 is bonding through conductive glue and wheel hub 13; 2, the tyre bead installation that attaches the clump weight of installing on bar 4 and the wheel hub 13 is pressed from both sides 14 and is connected.In addition, for guaranteeing dynamic balance of wheel, static discharges the attaching bar and on wheel, is symmetric arrangement.
In addition; For promptly there being the circumferential pattern groove that the vehicle tyre of cros-rib tread groove is arranged again on the tyre surface, then can a part that vertically attaches bar and connecting strap be embedded in the another part and the horizontal cros-rib tread groove that attaches on the bar embedding tyre surface in the circumferential pattern groove on the tyre surface, with connecting strap.Can when making wheel, static be discharged the attaching bar for new wheel and join in the wheel,, then can static release be attached bar and join in the wheel through equipped mode for used wheel.
