Abstract
The utility model provides a pneumatic support leg of a trailer, which relates to a trailer accessory, in particular to the improvement of a support leg with the support effect on the front part of the trailer. The pneumatic support leg comprises two support legs (1): a left support leg and a right support leg, wherein each support leg (1) consists of an outer casing (2), a support foot (3) and a driving assembly for driving the support foot (3) to ascend and descend, a differential mechanism assembly (4) is connected between the two support legs (1), and two semi shafts of the differential mechanism assembly (4) are respectively connected with the driving ends of the driving assemblies of the two support legs (1). The utility model has the advantages of simple structure and low manufacture cost, saves time and labor during the operation, and is applicable to the new trailer installation and the old trailer reformation.
Description
Technical field
The utility model relates to the trailer accessory, is specifically related to a kind of improvement that is used for the anterior passive supporting leg of trailer.
Background technology
Requisite passive assembly when the trailer supporting leg is truck and trailer disengaging.Trailer supporting leg majority is manual structure at present, and high and low two gears are arranged, and the general high speed gear that adopts is earlier used low gear again instead during use when painstaking.Because the trailer railway carriage is longer, and very heavy, M/C is wasted time and energy, and brings very big burden to the trailer operator.In addition, also there is minority to adopt the supporting leg of hydraulic structure, but owing to need to increase extra fluid power system, and complex structure, has the high shortcoming of cost, be difficult on the trailer and popularize.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of simple in structure and pneumatic supporting leg of trailer that cost is low is provided.
Technical solution of the present utility model is: it comprises left and right two supporting legs, supporting leg is made of the driven unit of body skin, leg and the lifting of driving leg, it is characterized in that, be connected with differential assembly between described two supporting legs, two semiaxis of differential assembly are connected with the drive end of two supporting leg driven units respectively.
Technique effect of the present utility model is: it has advantage simple in structure and that cost is low, and it is time saving and energy saving to operate, and is suitable for new car and installs and old car transformation.
Description of drawings
Fig. 1 is a perspective view of the present utility model;
Fig. 2 is the connection structure scheme drawing of the utility model driven unit;
Fig. 3 is the sectional structure scheme drawing of the utility model driven unit transverse axis part.
The specific embodiment
As shown in Figure 1, it comprises left and right two supporting legs 1, supporting leg 1 is made of the driven unit of body skin 2, leg 3 and 3 liftings of driving leg, and 1 of described two supporting leg are connected with differential assembly 4, and two semiaxis of differential assembly 4 are connected with the drive end of two supporting legs, 1 driven unit respectively.
As shown in Figure 2, described driven unit by transverse axis 5 and vertical screw mandrel 6 and be separately fixed at transverse axis 5 and vertical screw mandrel 6 on horizontal finishing bevel gear cuter that is meshed 7 and vertical finishing bevel gear cuter 8 form, laterally finishing bevel gear cuter 7 and vertical finishing bevel gear cuter 8 are fixed in the body skin 2 free to rotately, be connected with the screw that cooperates with screw mandrel 6 on the leg 3, power is by transverse axis 5 inputs, turn to and drive legs 3 liftings by screw mandrel 6 by two finishing bevel gear cuters, two semiaxis of differential assembly 4 are connected with transverse axis 5 respectively.
Shown in Fig. 2 and 3, described driven unit also is provided with the duplex train of reduction gears that is made of big gear wheel 9 and miniature gears 10, its rotating shaft of train of reduction gears and transverse axis 5 secured in parallel are in body skin 2, described transverse axis 5 is made up of dead axle 11 and the moving axis that can axially be free to slide 12 that is enclosed within dead axle 11 inner ends, the teeth that the inner of moving axis 12 is provided with spline successively and matches with the big gear wheel 9 of train of reduction gears, described horizontal finishing bevel gear cuter 7 outsides are provided with the miniature gears 10 mating teeth teeth with train of reduction gears, laterally the inside portion of finishing bevel gear cuter 7 axis holes is provided with the spline that matches with the spline of moving axis 12 the inners, when moving axis 12 cooperates with horizontal finishing bevel gear cuter 7, its teeth are separated mutually with the big gear wheel 9 of train of reduction gears, power is at a high speed when being imported by moving axis 12 or dead axle 11, when moving axis 12 matches with the big gear wheel 9 of train of reduction gears, its spline separates with the spline of horizontal finishing bevel gear cuter 7, and power is low speed when being imported by moving axis 12.
The utility model can be by pneumatic and manual driven in two modes supporting leg.When adopting the train of reduction gears structure, manual mode can have high and low two shelves speed.For guarantee that left and right two supporting legs 1 can rise or descend simultaneously when driving, can be in two ways, left and right two moving axis 12 of the first only need the opposite design of thread rotary orientation of left and right two screw mandrels 6 is got final product all toward the outer side this moment.It two is only to use the train of reduction gears structure in a side supporting leg 1, and opposite side adopts whole transverse axis 5, notices that the installation site of horizontal finishing bevel gear cuter 7 get final product, so then can only have a side that high and low two shelves speed can be arranged when manual.
When the utility model adopted pneumatic actuation, diff can solve well when ground and be uneven or the soft or hard problem of two supporting leg 1 force balances simultaneously not.The utility model also can directly be transformed old car.Differential assembly 4 can directly adopt the structure of motor-tricycle back axle, when connecting with transverse axis 5, can hole on differential assembly 4 semiaxis and transverse axis 5, uses sleeve pipe and bolt to connect.Pneumatic actuating device both can adopt special-purpose pneumatics to captive joint with the input end of differential assembly 4, also can directly adopt air nutsetter, by operator's hand-held.When adopting air nutsetter, fix nut earlier, use supporting casinghead get final product, so both can be used as the driver's tool use again for supporting leg 1 provides power at the mouth of air nutsetter at the input end of differential assembly 4.
