Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
Refer to Fig. 1 and Fig. 2, the two-way expanded shelter transmission device of big-and-middle-sized caravan, comprise dual output drive motor 1 and two extension mechanisms.Two extension mechanism anterior-posterior horizontal are opposite to dual output drive motor 1 two ends, and each extension mechanism comprises reductor 2, diff 3 and lead screw pair 4.The DC machine that dual output drive motor 1 is preferably identical with vehicle electrical system voltage, such as 24V DC machine; Dual output drive motor 1 is powered through storage battery or automobile current generator, to meet the needs of Power output.The frame of dual output drive motor 1 is fastened on DC machine adapter plate by bolt and rubber pad; DC machine adapter plate is then fastened on the left-right longeron of chassis by U-bolt by U-bolt binding.Dual output drive motor 1 output shaft is through flat key, and clamp nut is also connected by the flange flange secures of bolt with main gear reducer 2.The output shaft center of dual output drive motor 1 and main gear reducer 2 input shaft central coaxial; Simultaneously with left and right leading screw 4a axis in same plane.Reductor 2 adopts driving and driven finishing bevel gear cuter structure, plays to change transmission of power direction and slow down to increase the effect of square.Diff 3 is satellite differential preferably; Described diff 3 is made up of differential gear box, compensating-gear shaft, planetary wheel, axle side gear.The power of drive motor 1, after reductor 2, passes to diff 3, then passes to left and right lead screw pair 4.Concrete transmission of power circuit is drive bevel gear → driven wheel of differential → differential gear box → compensating-gear shaft → planetary wheel → axle side gear → lead screw pair 4.
The parts of reductor 2 and diff 3 can the main reduction gear parts of automobile rear-guard of preferred maturity, and main reduction gear component assembly incorporates reductor 2 and diff 3, both is included in a housing; Compact conformation.The both sides axle side gear of diff 3 and screw mandrel 4a spline joint.Power, through axle side gear, passes to left and right screw mandrel 4a by spline.The hand of spiral of left and right screw mandrel 4a is contrary, and left side can be minus thread, and corresponding right side is right-hand screw thread; Flat opposed in dual output drive motor 1 the other end the left and right screw mandrel hand of spiral of extension mechanism then continue on the contrary, left side is right-hand screw thread, and right side is minus thread.Corresponding its screw thread of feed screw nut 4b mates with screw mandrel 4a, forms lead screw pair 4, make the rotation of screw mandrel 4a become the straight-line motion of nut 4b by the cooperation of screw mandrel 4a and nut 4b.So, when input redirect is determined, the feed screw nut at two ends is reverse linear motions.Screw mandrel supporting shell 5 material is cast iron, and being provided with cross section is that U-shaped feed screw nut moves chamber 6, U-shaped opening upwards.Screw mandrel supporting shell 5 is affixed by the housing of bolt and main reduction gear parts, is then anchored on left-right longeron by U-bolt with adapter plate.The structure at the two ends, left and right of screw mandrel supporting shell 5 is cylinder axis bearings 7, interior assembling deep groove ball bearing 10 and bearing air cover 8.Bearings at both ends transparent cover 8 uses bolted in the end face of screw mandrel supporting shell 5.In order to dust-proof, bearing air cover 8 is built with dust-proof felt 9; The move opening both sides in chamber 6 of supporting shell 5 feed screw nut are provided with dust protection rubber plate 11 along its length.Respectively there are four tapped bore feed screw nut 4b upper surface, left and right, match with upper four screw (unthreaded hole) positions of the web (preferably web length is identical with expanded shelter length) bottom the expanded shelter of left and right, and fastening by socket bolt.When wanting expanded shelter, through transmission of power, expanded shelter is driven to move by feed screw nut 4b; Realize left and right expansion simultaneously or shrink.
In order to increase the stability that expanded shelter moves in parallel further, correct position before and after expanded shelter, being configured with T-shaped guide groove plate and constituting expansion slideway.T-shaped guide groove plate length is mated with expanded shelter length; And with two extension mechanisms before and after be arranged symmetrically with.T-shaped guide groove plate two ends U-bolt will be anchored on the left-right longeron on chassis by U-bolt binding; Each T-shaped guide groove plate coupling has T-shaped blade fin; Fastening by socket head cap screw compartment corresponding to below compartment web in the middle part of T-shaped blade fin; Expanded shelter can be allowed to move freely along T-shaped guide groove plate, thus realize the expand and contract in compartment.For ensureing that the fastening height in the left and right sides, compartment and feed screw nut and compartment is in same plane, if desired by adjustment pad adjusting pad in left-right longeron and the T-slot Board position that leads, to adjust to equal altitudes.
