Description
Affiliated technical field
The utility model relates to a kind of spare tyre jacking system that is installed under automobile rear, the crossbeam.
Background technology
At present, existing automobile spare tire jacking system is the lifter that is made of spare tyre supporting plate, chain link, internal tooth bull wheel, external tooth steamboat, gear wheel shaft and parts thereof.In the lifter iron-clad, miniature gears is installed among the bull wheel internal tooth, and bull wheel outside tooth and chain link are meshing.The part of gear wheel shaft is a concentric shafts, matches with big axle hole, and another part is that eccentric shaft and miniature gears axis hole match, and the miniature gears outside is cast with directed slide block, and has directed slide plate to be installed between miniature gears and the housing.Miniature gears under the qualification of directed slide plate, under the effect of eccentric shaft and horizontally slip, meshing bull wheel internal tooth and rotate bull wheel, tooth driving chain endless belt moving supporting plate in the bull wheel outside is realized lifting with spare tyre.Simultaneously miniature gears plays the spare tyre locking action under the effect of the qualification of slide plate and eccentric shaft.But, existing jacking system has such problem: 1, miniature gears is under the qualification of directed slide plate, eccentric shaft rotates a week, miniature gears horizontally slips, the work done of meshing bull wheel internal tooth once, bull wheel outside driving gear is again less than bull wheel, so the spare tyre rising or falling speed is slow, the operating time is long, all numbers of rocking-turn are many.2, automobile is in the middle of travelling, and tire is subjected to ground-surface resistance and friction and produces big bump to shake, and the traction of spare tyre own wt and vibrations have in addition increased the weight of the bearing capacity of chain link and miniature gears.Time is permanent, the chain link easy fracture, and meshing wearing and tearing aggravation mutually of miniature gears and bull wheel internal tooth easily causes gear to skid or get loose.The driver has no consciousness ground and loses spare tyre in driving.3, the dust silt that taken up in the process of travelling of automobile easily stockpiles between big miniature gears, and the between cog bed hedgehopping has been changed meshing the degree of depth and the control position of gear wheel shaft, makes it to rotate difficulty, has increased the weight of labor intensity of operating personnel.
Summary of the invention
In order to overcome the existing existing chain link easy fracture of spare tyre lifter, gear skids and gets loose, the operating time is long deficiency, the utility model provides a kind of reel warning spare tyre jacking system.This installs not only that spare tyre gets loose and can in time report to the police, and can shorten working hours, and alleviates labor intensity of operating personnel.
The technical scheme in the invention for solving the technical problem is: the gear cluster of an one concentric structure is installed in the lifter housing, and two ends are the fastening gear of helical teeth, and centre portion is an empty stomach chamber reel, and the wheel body central shaft hole is square.The gear wheel shaft two ends are that circular shaft and housing both sides axis hole match, and the square opening and prism of the square shaft of centre portion and one nebenkern matches, and the gear wheel shaft bigger diameter end has interior circular hole, cross a starting pin in the middle of the hole.Gear wheel shaft inserts from the housing axis hole, pass reel and fastening gear square opening and prism after, stretch out the lock opening pin by the housing axis hole.Two locking card pressure springs are ridden respectively and are pressed on two locking cards, axle inserts from the housing axis hole, after passing the stage clip ring and locking the card intermediate shaft hole, is stretched out by housing bore, the lock opening pin, the head of locking card and the between cog of fastening gear helical teeth match, and afterbody contacts with eccentric wheel, and two eccentric wheel are installed in the afterbody of two locking cards respectively, freeing axle inserts from the housing axis hole, after passing the eccentric wheel axis hole, stretch out the lock opening pin by the housing axis hole.One end of steel rope is fixed on the reel, and the other end is fixed in the supporting plate pin centre hole.Alarm switch is installed in the switch seat hole of housing, contacts with the spare tyre supporting plate.Two binding posts on the alarm switch are connected with lead and the automobile power source line annunciator interior with being installed in operator's compartment respectively.When needing to rise spare tyre, the spare tyre supporting plate is placed on below the spare tyre steel plate centre hole, the locating piece of two ends of bearing plate is stuck on the edge of centre hole, the drive link open end is inserted in the gear wheel shaft starting pin-and-hole, partly going on foot spanner (having this instrument or manufacturer to bring with car) is enclosed within on the drive link square toes, back and forth pull spanner, twisting drive link driven gear axle rotates with the one nebenkern, locking is stuck under the effect of pressure spring, head intermittently is stuck between the helical teeth of fastening gear, constantly twined by steel rope by reel, pulling supporting plate pin promotes the spare tyre supporting plate and holds up spare tyre through recoil spring, when supporting plate backs down alarm switch, when spare tyre is adjacent to crossbeam, extract drive link out, rise spare tyre work and promptly finish.When needing the landing spare tyre, the drive link open end is inserted in the gear wheel shaft starting pin-and-hole, twist drive link with spanner, drive is freed axle and is rotated with eccentric wheel, when eccentric position with the power work done during in locking card afterbody, locking dop portion just lifts and breaks away from the between cog of fastening gear helical teeth, the spare tyre ground of landing back under the gravitation of deadweight.Alarm switch has broken away from the top power effect of spare tyre supporting plate, under the effect of inner spring, and energized, annunciator just sends alerting signal.The utility model has reached the purpose that spare tyre gets loose and can in time report to the police, shortens working hours, reduce labor intensity.
The beneficial effects of the utility model are, reel and the fastening gear that plays locking action adopt the one concentric structure, rotation synchronously, two locking cards are stuck in two fastening teeths wheel between cog simultaneously, thereby have ensured the fastness of spare tyre location.Because spare tyre is attached on the supporting plate, supporting plate contacts with alarm switch again, has only supporting plate loosening, and spare tyre just can get loose; Supporting plate is loosening just to be separated with alarm switch, can in time report to the police so spare tyre gets loose, and has guaranteed the safety of spare tyre.Owing to the reel lay winding wire ropes holds up spare tyre, the locking card breaks away from fastening teeth wheel between cog and the spare tyre that lands, thereby can shorten working hours, and reduces labor intensity.
