Description

Wheel scotch block for securing automobiles

(1) technical field:

Wheel scotch block for securing automobiles belongs to the goods train vehicle accessory.It and railway are carried the supporting use of back of the body car on the back, are used for fixing the restriction shipment and carry the automotive wheel of carrying on the back on the flatcar at railway on the back.

(2) background technology:

Railing roadlice and railway are carried unlucky defeated difference with essence on the back, rolling stock shipment roadlice, roadlice is as goods, be characterized in light unit weight, quantity is many relatively, and railway is carried unlucky failing on the back, the highway superimposed trailer or the truck of rolling stock shipment, goods comprises the goods in automobile and the automobile, be characterized in that unit weight is heavy, and quantity is single.These characteristics determine the wheel stopping device of existing railing roadlice not to be applicable to carry on the back unlucky defeated, carry the unlucky demand of fixing vehicle wheel when defeated on the back in order to realize railway, must a kind of later-model special-purpose wheel stopping device of design.

(3) summary of the invention:

The problem to be solved in the present invention be exactly for realize railway carry on the back unlucky when defeated fixing vehicle wheel purpose and a kind of special-purpose wheel stopping device and the supporting use of car body are provided.Its technical scheme is as follows:

It comprises wheel skid body, base and hand-held rod, its gordian technique is in the housing of wheel skid body imput shaft to be installed, key wheel, power-transfer clutch, ratchet and miniature gears are installed on the imput shaft successively, be equipped with driven axle driven axle on parallel with imput shaft is equipped with big gear wheel in the housing of wheel skid body, big gear wheel and pinion; In the housing of wheel skid body, the sour jujube tongue is installed by bearing; The engagement of tooth bar and big gear wheel is installed on base.

Advantage compared with prior art of the present invention is: 1, this wheel skid is applicable to and carries unlucky failing on the back, can realize step-less adjustment lock wheel gap, reduces the impact of transport vehicle, guarantees transportation safety.2, simple and efficient to handle, can realize locking the function of wheel and release by steering handwheel.

(5) specific embodiment:

Referring to Fig. 1--Fig. 5 the present invention includes wheel skid body 4, base 5 and hand-held rod 1.Its gordian technique is that imput shaft 13 is installed in the housing of wheel skid body 4, and key wheel 8, power-transfer clutch 9, ratchet 10 and miniature gears 11 are installed on the imput shaft successively.The parallel driven axle 12 that is equipped with imput shaft is equipped with big gear wheel 7 on the driven axle 12 in the housing of wheel skid body, big gear wheel 7 and miniature gears 11 engagements.Above key wheel 8 is to have end tooth on key wheel body, and the surface of end tooth is an end tooth face 8.1; Power-transfer clutch 9 is to be distributed with rectangle end tooth 9.1 in clutch body one side, the opposite side end tooth 9.3 that distributing twist, and the inside face of end tooth 9.3 constitutes spiral camber 9.2; Has curved surface 11.1 on the miniature gears 11.The end tooth face 8.1 of key wheel 8 and the spiral camber 9.2 of power-transfer clutch 9 active flank that partners; Rectangle end tooth 9.1 on the power-transfer clutch 9 remains and ratchet 10 engagements; And the active flank that partners of the curved surface 11.1 on the surface of rectangle end tooth 9.1 and the miniature gears 11.By swaying of key wheel 8, promote power-transfer clutch 9 and move axially, power-transfer clutch 9 is in engagement or non-engagement state with miniature gears 11, thus the transmission between drive or disconnection and the driven axle, the purpose that reaches locking or unclamp wheel.By bearing sour jujube tongue 14 is installed in the housing of wheel skid body, has ratchet on the ratchet 10, the surface of ratchet is a ratchet face 10.1, and the surface of sour jujube tongue 14 ends is a tongue end face 14.1, and tongue end face 14.1 is adjacent to ratchet face 10.1.Tooth bar 6 and big gear wheel 7 engagements are installed on base 5.Imput shaft end outside being positioned at wheel skid body housing is equipped with handwheel 2.Round pin 3 is installed on base 5.

Its principle of work is:

Referring to Fig. 1-Fig. 4, utilize hand-held rod 1 that wheel skid is placed near the lorry body floor that needs the fixing automotive wheel 15, the round pin 3 on the base 5 is snapped in the circular hole of floor, fixedly the wheel skid base 5.After superimposed trailer or truck hang lorry body, right-hand revolution handwheel 2, the control handwheel drives imput shaft 13 and rotates, end tooth face 8.1 on the key wheel 8 promotes power-transfer clutch 9 and can only move axially along imput shaft, the rectangle end tooth 9.1 of a side puts in the curved surface 11.1 on the miniature gears 11 again and drives pinion rotation after putting in ratchet 10 on the power-transfer clutch, miniature gears and imput shaft, ratchet are joined together indirectly, thereby driving the big gear wheel 7 that is meshed therewith rotates, the tooth bar 6 of big gear wheel on base 5 relatively moves, and drives wheel skid body 4 and relatively moves.Because the ratchet on the imput shaft is under the deadweight effect of sour jujube tongue 14, the tongue end face 14.1 of sour jujube tongue 14 is adjacent to ratchet face 10.1, the restriction ratchet can only folk prescription to rotation, promptly limit the backward rotation of imput shaft.Thereby drive big gear wheel and can only make unidirectional straight-line motion by the tooth bar on base, make wheel skid show consideration for nearly wheel 15 and locking, promptly can realize the purpose of fixed constraints wheel.

In the time of need unclamping wheel, referring to Fig. 1, Fig. 2, Fig. 3, Fig. 5, the end tooth 9.3 because the clutch body opposite side is distributing twist, at this moment the anti-clockwise rotation handwheel is 2 about 30 °, the end tooth face 8.1 of key wheel 8 and 9.2 engagements of the spiral camber of power-transfer clutch 9, end tooth face 8.1 on the key wheel promotes power-transfer clutch and can only oppositely move axially along imput shaft, the power-transfer clutch rectangle end tooth 9.1 that puts in miniature gears is broken away from miniature gears, miniature gears and imput shaft, the annexation of ratchet is removed, miniature gears can rotate relative to imput shaft, imput shaft 13 disconnects with the transmission of driven axle 12, and at this moment available pulling moved the external wheel that moves away of wheel skid, thereby unclamps wheel.
