Description
Technical field
The utility model relates to vehicle class, and particularly a kind of van-type caravan refers to a kind of flexible van-type caravan especially.
Background technology
As everyone knows, in order to satisfy the needs of open-air special public affair, adopt a kind of caravan office function and vital function, vehicle body space extending/drawing back type that has usually.
As shown in Figure 1, the guide track system of the general flexible van-type caravan of using always and synchro system adopt chain, sprocket wheel and tightening device etc., its complex structure, guide rail is coarse unsmooth, cause envelope resistance in the companding process big, need bigger promotion power, make the manufacturing cost of caravan big, also influence the alerting ability of caravan vehicle body space telescopic.In addition, caravan commonly used adopts more coarse guide track system, usually only arrange two rollers between guide rail and the track base 4 ', roller is arranged on the movable guiding rail 3 ', and rail length is too short, guide precision is not enough, cause the guide rail of flexible envelope 2 ' bottom to run off the spacing of fixed guide seat 4 ' easily, and it is excessive that flexible envelope 1 ' sag of chain takes place, left and right sides envelope tilts to outer end, main envelope 1 ' both sides respectively, must supporting leg 16 ', not only complex structure be installed in the outer end of the envelope 2 ' that stretches out for this reason, and the increase cost, need be improved.
The utility model content
The purpose of this utility model is to provide a kind of flexible van-type caravan, and it is complicated to have solved caravan structure commonly used, and resistance is big in the companding process, the problems such as very flexible of manufacturing cost height and vehicle body space telescopic.
The technical solution of the utility model is: cancelled supporting leg and coarse transmission elements such as chain, sprocket wheel and chain anxiety device in the existing caravan, the roller transfer that is arranged on the movable guiding rail is arranged on the fixed guide seat, and increased the number of roller, make movable guiding rail accept the accurate guiding of fixed guide seat all the time, the mating part of roller and axle adopts antifriction-bearing box to reduce the flexible frictional resistance of envelope, makes the flexible envelope flexible state that manpower can promote when mobile on guide rail; In addition, the utility model adopts gear transmission to control flexible envelope left and right displacement harmony, replaced chain-driving of the prior art, can accurately handle the displacement of flexible envelope like this, make the sag of chain after the vehicle/caravan expansion envelope stretches out be not more than 2cm, the degree of dip of guide rail is not more than 1 degree, reaches the purpose of cancellation supporting leg.
Structure of the present utility model is: comprise main envelope, flexible envelope, movable guiding rail, fixed guide, roller, tooth bar, hydraulic gear, synchronizing shaft, bearing, gear, reducing motor and retarder, main envelope is connected by the rolling that movable guiding rail and fixed guide seat keep good with flexible envelope, and this main envelope is provided with transmission device; This movable guiding rail is an I-shape, and the both sides of this fixed guide seat are respectively equipped with four rolling; This movable guiding rail is connected under the base plate of flexible envelope, interts in cooresponding fixed guide seat, and the length of movable guiding rail is 1.5～2 times of fixed guide seat length; Synchronizing shaft is arranged on vertical symmetrical center line of main envelope base plate, and the two ends of this synchronizing shaft are equiped with gear, and the inboard of this gear is equiped with bearing; Be connected with two tooth bars on the flexible envelope base plate and be meshed, thereby keep the synchronism of flexible envelope rear and front end displacement with the gear at synchronizing shaft two ends;
Wherein, transmission device is a hydraulic gear;
The transmission device that this transmission device also can be made up of reducing motor and retarder, this reducing motor is connected on the synchronizing shaft by retarder, thereby drive synchronizing shaft, gear and tooth bar,, drive flexible envelope telescopic displacement;
The surface of main envelope and flexible envelope is to be made by aluminum alloy plug-in type section bar or color steel.
Advantage of the present utility model is: rational in infrastructure, easy and simple to handle, balance is reliable, and is practical.
