Description
Technical field
The utility model belongs to whole vehicle Performance Detection field, relates to a kind of power wagon and tested vehicle coupling hitch.
Background technology
Power wagon is mainly the test needs meeting domestic various agricultural and off roader, particularly provides necessary research technique for traction power test in GB/T3871.9-2008 agricultural traction engine testing regulations.Also the various traveling loads of tested vehicle can be simulated, carry out the test of the aspect such as thermal equilibrium, heat management, grade climbing performance, hauling ability under car load peak load, with thoroughly evaluating by the hauling ability of sample machine and economy, be the important tests equipment that vehicle carries out qualification test and detection.The utility model is the core component that traction load car weight is wanted, and for the connection of traction load car and tested vehicle, transmits and detects tractive force.Power wagon do there is skidding in tractive force process of the test time, tested vehicle has very large inertial force, can produce pinch shock power, thus cause sensor degradation to the pulling force sensor in draw-gear.If the excessive pulling force sensor hanger that may cause of tractive force is pulled in addition, and then causes tested vehicle and power wagon throw off suddenly and occur danger.Therefore, the coupling hitch developing a kind of compact conformation, safe and reliable power wagon and tested vehicle is completely necessary.
Utility model content
The purpose of this utility model is to provide one that pulling force sensor can be protected not to be squeezed impact, and power wagon and tested vehicle can be avoided again to occur pulling the adjustable for height power wagon and tested vehicle coupling hitch of causing danger.
The technical solution of the utility model is: power wagon and tested vehicle coupling hitch, comprising: motor, leading screw, traction stake, slide block, upper locating piece, long pin shaft, protective shield, pull bar, short pin shaft, traction guide plate, sensor hanger, sleeve, pulling force sensor, axle sleeve, guide pillar, traction arm-tie, lower locating piece, feed screw nut; Traction stake is connected with traction load car by long pin shaft; Motor is installed on traction stake top, and leading screw is connected with motor, and slide up and down in the chute that slide block can be arranged in traction stake, feed screw nut, upper locating piece are mounted in slide block, and lower locating piece is fixedly installed in bottom traction stake; Traction arm-tie is connected with slide block by short pin shaft; Guide pillar is affixed with traction arm-tie; Pulling force sensor two ends respectively connect a sensor hanger, and one of them sensor hanger is connected with traction arm-tie by short pin shaft, and another sensor hanger is connected with traction guide plate by short pin shaft.Sleeve is affixed with traction guide plate; Protective shield by short pin shaft with traction arm-tie with draw guide plate and link together; Pull bar is connected with traction guide plate by short pin shaft; Guide pillar is set with axle sleeve and sleeve.
The good effect that the utility model produces after adopting technique scheme is: this device is tested vehicle and the device be connected between power wagon in tractive force test.Owing to doing in tractive force process of the test, pulling force sensor often can be subject to the pinch shock of tested vehicle and power wagon, and pulling force sensor is fragile.This device can effectively avoid this kind of situation to occur.In addition, this device height adjustable, can use differing heights vehicle to do tractive force test.

Accompanying drawing 2 is the plan structure schematic diagram of the utility model power wagon and tested vehicle coupling hitch.
Accompanying drawing 3 is the left TV structure schematic diagram of the utility model power wagon and tested vehicle coupling hitch.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.As shown in Figures 1 to 3, power wagon and tested vehicle coupling hitch, mainly comprise: motor 1, leading screw 2, traction stake 3, slide block 4, upper locating piece 5, long pin shaft 6, protective shield 7, pull bar 8, short pin shaft 9, traction guide plate 10, sensor hanger 11, sleeve 12, pulling force sensor 13, axle sleeve 14, guide pillar 15, traction arm-tie 16, lower locating piece 17, feed screw nut 18; Traction stake 3 is connected with traction load car by long pin shaft 6; Motor 1 is installed on traction stake 3 top, and leading screw 2 is connected with motor 1, drives rotation by motor 1.Slide up and down in the chute that slide block 4 can be arranged in traction stake 3, feed screw nut 18, upper locating piece 5 are mounted in slide block 4, and feed screw nut 18 and leading screw 2 mating band movable slider 4 slide up and down in the chute drawing stake 3.Upper locating piece 5 is mounted on slide block 4 appropriate location.Lower locating piece 17 is fixedly installed in bottom traction stake 3; Traction arm-tie 16 is connected with slide block 4 by short pin shaft 9; Together with guide pillar 15 is affixed with traction arm-tie 16.Together with sleeve 12 is affixed with traction guide plate 10.Protective shield 7 is by short pin shaft 9 and traction arm-tie 16 and draw guide plate 10 and connect together; Pull bar 8 is connected with traction guide plate 10 by short pin shaft 9.Pulling force sensor 3 two ends respectively connect a sensor hanger 11, and one of them sensor hanger 11 is connected with traction arm-tie 16 by short pin shaft 9, and another sensor hanger 11 is connected with traction guide plate 10 by short pin shaft 9.Guide pillar 15 is set with axle sleeve 14 and sleeve 2.
Ensure during assembling that axle sleeve 14 two ends hold out against gapless with sleeve 12 and guide pillar 15 respectively.Simultaneously sensor hanger 11 hole is elongated hole, ensures that the elongated hole of sensor hanger 11 has gap with short pin shaft 9 by sensor 13 side during assembling, and like this when draw-gear is squeezed impact, impulsive force is born by axle sleeve 14, and sensor 13 would not be squeezed power.
The pin-and-hole at protective shield 7 two ends is elongated hole, install after and short pin shaft 9 length direction have certain interval, the detection of sensor 13 can not be affected.If sensor 13 and sensor hanger 11 are because of stressed excessive and throw off in pulling test process, protective shield 7 can also continue to bear pulling force and ensure that traction load car can not be thrown off with tested vehicle.
During work, starter motor 1, motor 1 drives leading screw 2 to rotate, and leading screw 2 drives feed screw nut 18 and slide block 4 to rise or decline and adjusts pull bar 8 height simultaneously.Pull bar 8 connects upper tested vehicle.When slide block 4 drops to certain position, the upper locating piece 5 on slide block 4 just withstands lower locating piece 17, and prevent feed screw nut 18 from deviating from leading screw 2, now pull bar 8 is in lowest limit position.
