Description
Technical field
The utility model belongs to power and wheels-locked testing technical field, is related to a kind of power of tire and brake test table diameter
To load maintainer.
Background technology
Tire subjects larger active force in radial directions during actual loading.For more preferable simulation and
Tire complicated force-bearing situation in actual operation is analyzed, in order to better adapt to the tire of plurality of specifications, multiple diameter size
Can carry out simulation test in laboratory, need to develop a kind of adjustment is easy to operate, adjusting range is big, diameter that Adjustment precision is high
To load maintainer.
Utility model content
The purpose of this utility model is to provide a kind of power of tire and brake test table radial loaded mechanism, this practicalities
Novel advantageous effect is that the radial direction adjusting range of radial loaded mechanism is big, device structure is compact, small, light-weight.
Technical solution used by the utility model be include hydraulic cylinder, hydraulic cylinder is fixed by way of forward flange installation
It on crossbeam, is lifted with the lifting of crossbeam, the crossbeam both ends of babinet girder construction are equipped with screw thread elevator, screw thread elevator
On lead screw, the upper and lower ends of lead screw are fixed on by screw flange in the rack of test bench installation, motor reducer
Respectively by shaft coupling and universal shaft connection screw thread elevator, the rotating nuts in screw thread elevator subtract both ends output shaft in motor
When being rotated under the drive of fast machine, lead screw does not turn, and makes crossbeam as hoistable platform, moves up and down, in the piston rod front end of hydraulic cylinder
Pressure sensor is connected by transit joint, pressure sensor is mounted between piston rod and earrings.
Further, pressure sensor and piston rod are concentric, can be under the premise of not influencing force structure, and detection in real time adds
The stressing conditions of load.
Description of the drawings
Fig. 1 is the front view of radial loaded mechanism；
Fig. 2 is the vertical view of radial loaded mechanism.
In figure, 1. hydraulic cylinders, 2. motor reducers, 3. shaft couplings, 4. universal shafts, 5. screw flanges, 6. screw thread elevators,
7. crossbeam, 8. lead screws, 9. piston rods, 10. transit joints, 11. pressure sensors, 12. earrings.
Specific implementation mode
The utility model is described in detail With reference to embodiment.
The utility model is as depicted in figs. 1 and 2, and hydraulic cylinder 1 is fixed on by way of forward flange installation on crossbeam 7, with
It the lifting of crossbeam 7 and lifts.7 both ends of crossbeam of babinet girder construction are equipped with screw thread elevator 6, and screw thread elevator 6 is mounted on
On lead screw 8, the upper and lower ends of lead screw 8 are fixed on by screw flange 5 in the rack of test bench installation, and the two of motor reducer 2
Hold output shaft respectively by 4 connection screw thread elevator 6 of shaft coupling 3 and universal shaft, the rotating nuts in screw thread elevator 6 are in motor
When being rotated under the drive of speed reducer 2, lead screw 8 does not turn, and so that crossbeam 7 is used as hoistable platform, moves up and down.In the piston of hydraulic cylinder 1
9 front end of bar connects pressure sensor 11 by transit joint 10, and pressure sensor 11 is mounted between piston rod 9 and earrings 12,
Pressure sensor 11 and piston rod 9 are concentric, can be under the premise of not influencing force structure, the stress feelings of detection load in real time
Condition.After earrings 12 is connect with loading component, piston rod 11 slowly stretches out；When the numerical value of pressure sensor 11 reaches predetermined value
When, stop motion completes being accurately positioned for radial loaded mechanism, and load at this time is defined as zero.
The advantages of radial loaded mechanism of the utility model, is two screw thread elevators 6 being mounted on babinet girder construction
On crossbeam 7, the upper and lower ends of lead screw 8 are fixed on the rack with flange, and the rotating nuts in such screw thread elevator 6 subtract in motor
When being rotated under the drive of fast machine 2, lead screw 8 does not turn, and so that crossbeam 7 is used as hoistable platform, moves up and down.Whole equipment is compact-sized,
It is small, light-weight, two screw thread elevators 6 are applied in combination, adjustment hoisting depth can be accurately controlled, use motor reducer
2 drivings, motor reducer 2 are connected with the two screw thread elevators 6 in left and right respectively by two universal shafts 4, provide same rotational speed
Synchronous dynamic ensure that the lift in height at crossbeam both ends synchronizes, complete the coarse positioning of radial loaded.
The above is only the better embodiment to the utility model, not makees any form to the utility model
On limitation, every any simple modification made to embodiment of above according to the technical essence of the utility model is equivalent to become
Change and modify, is all within the scope of the technical scheme of the utility model.
