Abstract
The utility model relates to a self-locking type two-direction torsion-lever lock-releasing spare wheel lifter, and the utility model is composed of a housing, an eccentric shaft, a torsion bar lock-releasing device, a metal chain type supporting bracket, a group of planetary wheels with cycloid, etc. The utility model has the advantages of small size, light weight, high capability, convenient operation, reliable working, low cost, convenient installation, etc.; the utility model is suitable for lifting and lowering a spare wheel arranged on the chassis of large, middle and small trucks, and the utility model can also be used as a universal and independent lifting device assembly.
Description
The utility model relates to a kind of self locking type bidirectional torsion bar release spare tyre lifter that is applicable to the lifting of big-and-middle-sized truck chassis spare tyre.
Existing big-and-middle-sized truck chassis spare tyre lifter adopts cycloid in planet to slow down, and metallic bond promotes and falls spare tyre, manually with nut locking or unclamp and realize the fixing of spare tyre or unload usefulness.Though this mode can be finished predetermined work reliably, because operating sequence is many, it is long to change the tire time, transports to road and brings certain difficulty.
To be that design is a kind of have an auto-lock function to the purpose of this utility model, torsion bar torsion unlocking operation save time automobile-used easily chassis spare tyre lifter, i.e. self locking type bidirectional torsion bar release spare tyre lifter.
The technology solution route is: the utility model is made of housing, eccentric shaft, lock tube, Cycloidal Wheel, carriage, spring cotter, pad, satellite gear, lifting metallic bond and self-locking device, described self-locking device places in the eccentric shaft, by core, pull back spring, steel ball, sheath are formed, steel ball places between eccentric shaft, core and the lock tube, the lifting metallic bond rides in the key way of Cycloidal Wheel, one end and carriage join, the other end is fixed on the housing, eccentric shaft is by the built-in slide block of housing, Cycloidal Wheel and fixing, satellite gear is fixed on the housing by hatch lock.
The utlity model has rational in infrastructurely, volume is little, and load-carrying capacity is big, the reliable operation nature, and easy for installation, cost is low, and can promote or descend to release with the operator, simplify the anchor fitting of Support-holder for spare tyre, and locking is reliable, only needs a torsion bar can allow the spare tyre lifting.
Below in conjunction with accompanying drawing the utility model is described in detail.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, the utility model revolves rail work by torsion bar pin (4) along the V-type chute on the eccentric shaft (5), core (3), steel ball (1) and return spring (2), lock tube (7) cooperates self-locking or release, and its course of work is as follows:
With torsion bar twisting torsion bar pin (4), torsion bar pin (4) revolves the rail motion along the upper V-type of eccentric shaft (5), pushes away Moving core (3) compression retracteding position spring (2) increases steel ball (1) free space, and steel ball this moment (1) loses Auto-lock function, eccentric shaft (5) just begins to move along the torsion bar direction, namely promotes or decline. Work as torsion bar The active force of lock on (4) less than return spring (2) return power the time, return spring (2) namely promotes core (3) move to torsion bar pin (4) direction, steel ball (1) enters the lock shaft face at this moment by the type groove of core (3) The hemisphere face of steel ball (1) diameter 2/5ths protrudes eccentric shaft (5) diameter, with interior half of lock tube (7) The circle engagement forms the rigidity self-locking.
Embodiment: with reference to Fig. 1, the utility model is by steel ball (1), pull back spring (2), core (3), torsion bar lock (4), eccentric shaft (5), sheath (6), lock tube (7), satellite gear (8), slide block (9), lifting metallic bond (10), housing (11), Cycloidal Wheel (12), spring cotter (13), pad (14), carriage (15) is formed.Sheath (6) plays dustproof effect, and core (3) is subjected to torsion bar lock (4) and pull back spring (2) control, and bidirectional torsion all can be realized release or lifting, when torsion bar pin (4) when not being subjected to external force, core (3) return is carried out self-locking, and the endplay of eccentric shaft (5) obtains by bearing cap shim (14).
Claims (1)
1, a kind of self locking type bidirectional torsion bar release spare tyre lifter, it is characterized in that by housing (11) eccentric shaft (5), lock tube (7), Cycloidal Wheel (12), carriage (15), spring cotter (13), pad (14), satellite gear (8), lifting metallic bond (10) and self-locking device constitute, and described self-locking device places in the eccentric shaft (5), by core (3), pull back spring (7), steel ball (1), sheath (6) is formed, and steel ball (1) places eccentric shaft (5), between core (3) and the lock tube (7), lifting metallic bond (10) rides in the key way of Cycloidal Wheel (12), and one end and carriage (15) join, and the other end is fixed on the housing (11), eccentric shaft (5) is by the built-in slide block (9) of housing (11), Cycloidal Wheel (12) and fixing, satellite gear (3) is fixed on the housing (1) by spring cotter (13), and lock tube (7) is welded on the housing (11).
