Description
Technical field
The utility model belongs to the vehicular spare parts technical field, is specifically related to a kind of disengaging type spare tyre lifter that is loaded on vehicle frame, is convenient to the spare tyre lifting and fixes.
Background technology
With car spare tyre lifter is the normal device that is equipped with of vehicle, common lifter is that rotating sprocket drives chain, utilization is packed in the moulding bed that holds of iron chains one end, the vertical lift spare tyre, rotating sprocket is by gear or worm and gear transmission, and this lifter is no doubt simple, but shake the effort time-consuming, rising device all needs to shake rocking bar when rising or descend, use inconvenient.June 1 1994 Granted publication day, notification number CN2167010Y disclosed a kind of automotive spare tire hoist, mainly contain the sprocket body of band chain annular groove, sprocket body one end has axis hole and positioning groove, with hold the iron chains that moulding bed links and be set on the sprocket wheel of sprocket body, and there is the support chain wheel body to trackslip, and the compositions such as support that can connect firmly with carriage frame, it is characterized in that sprocket body is provided with the sprocket wheel that two chain annular groove numbers do not wait, the long iron chains of end to end dead front type wears on two sprocket wheels by a rotation direction, other has the movable pulley connection to hold moulding bed, the movable pulley support is at the place that overhangs of long iron chains, and sprocket body also is provided with the ratchet constant-mesh that presses by elastic force on ratchet and the support.This spare tyre lifter also is to adopt crank to come rotating sprocket, drives spare tyre and rises, and the operation effort is time-consuming, can not control rate when discharging spare tyre and descend, use inconvenience.
The utility model content
For solving the above-mentioned defective that prior art exists, the purpose of this utility model is to provide a kind of compact conformation, has auto-lock function, and is safe and reliable, easy to operate, the disengaging type spare tyre lifter that folding and unfolding is controlled.
For achieving the above object, the technical solution adopted in the utility model: this disengaging type spare tyre lifter, have frame 1, capstan winch, capstan winch driver train, wire halyard and hold moulding bed, it is characterized in that: described capstan winch driver train comprises the ratchet 3 that the capstan winch sidewall constitutes, depression bar is sleeved in the rotating shaft of capstan winch, be hinged with the ratchet that matches with ratchet on the depression bar, frame is provided with the anti-rotation ratchet that prevents the ratchet reversing; The described moulding bed that holds is provided with movable pulley, and wire halyard is walked around the movable pulley two ends and is separately fixed on frame and the capstan winch; The capstan winch end face is connected with the power-transfer clutch that the control capstan winch rotates.
Described power-transfer clutch has platen, friction lining, hold-down mechanism and isolating construction, described friction lining is fixed on the platen, described hold-down mechanism has the compression spring that is arranged in the capstan winch, compression spring one end in contact capstan winch has the sidewall of power-transfer clutch side, and the other end compresses by gland and the hold-down nut that is engaged in the rotating shaft; Described isolating construction has the axially extending bore that is positioned in the rotating shaft, is provided with slidably backing pin in the through hole, and rotating shaft core is provided with the tapped bore that is communicated with through hole, is combined with in the tapped bore to promote the disengagement bolts that backing pin slides.
Described platen is a ratchet structure, and frame is provided with the ratchet that cooperates with ratchet.
The bearing that described capstan winch adopts is a thrust bearing.
Adopt the beneficial effect of technique scheme: the capstan winch driver train of this disengaging type spare tyre lifter adopts the click structure, crowbar or other instrument are inserted in the depression bar, by descending moulded rod repeatedly, stirring ratchet by ratchet rotates, capstan winch and ratchet are one, so capstan winch rotates, wire halyard is wrapped on the capstan winch, thereby the moulding bed rising is held in pulling.The pulley that holds on the moulding bed is a movable pulley, capstan winch is when the tractive wire halyard, only born half the power of moulding bed and spare tyre weight of holding, pass through the speed change of click on the capstan winch again, depression bar is very light in the process that hoists, and by the protection of the anti-rotation ratchet that prevents ratchet reversing, safe and reliable, and played the effect of self-locking.This capstan winch also is combined with power-transfer clutch, and when power-transfer clutch closed state, capstan winch made on the side friction lining that is fitted in power-transfer clutch tightly of capstan winch under the effect of inner holddown spring, and capstan winch and power-transfer clutch can only rotate around the direction of lifting.When needs decline spare tyre, open the anti-rotation ratchet on the frame, only need screw disengagement bolts, disengagement bolts promotes the backing pin slip and moves until promoting capstan winch, and capstan winch and friction lining are disengaged, and capstan winch rotates under the effect of gravity such as spare tyre, and spare tyre descends.By adjusting disengagement bolts, can regulate the friction force of capstan winch and friction lining, thereby the speed that the control spare tyre descends realizes automatic lowering.Compared with prior art, compact conformation, have auto-lock function, safe and reliable, easy to operate, folding and unfolding is controlled.
