Description

Radial fatigue testing machine for wheel

Technical Field

The utility model belongs to the technical field of the wheel production facility, a radial fatigue testing machine of wheel is related to.

Background

The radial fatigue test device for vehicle wheels is a special detection device for detecting the fatigue reliability of the road vehicle wheels. In general, in order to ensure the running safety and reliability of road vehicle wheels, radial fatigue performance verification is required to be carried out on the road vehicle wheels, namely, the continuous running state of the wheel and tire assembly is simulated to achieve the reliability verification.

The performance of the test device is determined by the authenticity of simulation, and the existing test device generally adopts a test under straight road surfaces and straight driving at different driving speeds, and can not simulate the performance of wheels under bumpy road surfaces and steering driving states.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a radial fatigue testing machine of wheel to the above-mentioned problem that prior art exists, the utility model aims to solve the technical problem how improve and detect the precision.

The purpose of the utility model can be realized by the following technical proposal: the utility model provides a radial fatigue test machine of wheel, its characterized in that, including seat, main shaft, pneumatic cylinder and four circumference evenly distributed's the detecting element in the main shaft outside, splined connection has a drive wheel on driving motor's the output shaft, constitute through the plane on the drive wheel and be connected with and the awl dish, rotate on the push rod of pneumatic cylinder and be connected with one with the cone pulley of awl dish adaptation, be connected with a reset spring between main shaft and the drive wheel, detecting element includes wheel seat, fixes connecting rod and the adjustment cylinder of setting on the seat on wheel seat on the wheel seat, adjustment cylinder's push rod with the connecting rod links to each other, waits to detect the wheel rotation and connects on wheel seat, the drive wheel can with wait to detect the wheel and lean on.

The driving motor is a speed reduction motor, the diameter of the speed reduction motor is far larger than the diameter of a wheel, torque can be transmitted to the wheel, and the efficiency and the reference basis can be improved by simultaneously detecting a plurality of wheels.

The pressing force between the wheels and the driving wheels is increased or decreased by controlling the adjusting cylinder to simulate different loads of the vehicle.

The cone pulley is close to the cone disc by controlling the hydraulic cylinder, so that the cone disc is driven to push the driving wheel to move along the axis direction of the main shaft, the wheel is subjected to external force in a non-radial direction, and non-radial acting force formed by feeding back the wheel when the vehicle turns and bumps the uneven road surface is simulated. Because the environment of simulation is more many units, can make the wheel detect more and be close to reality through the cooperation of pneumatic cylinder and adjust the cylinder, improve and detect the precision. The arrangement of each sensor in the scheme is the same as that of the prior art.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1 and 2, including the seat of arranging 1, main shaft 2, pneumatic cylinder 3 and four circumference evenly distributed's the detecting element in the main shaft 2 outside, splined connection has a drive wheel 4 on driving motor 9's the output shaft, be connected with through the plane constitution on the drive wheel 4 with conical disk 5, it is connected with a conical pulley 6 with conical disk 5 adaptation to rotate on pneumatic cylinder 3's the push rod, be connected with a reset spring 7 between main shaft 2 and the drive wheel 4, detecting element includes wheel arrangement frame 81, fix connecting rod 82 on wheel arrangement frame 81 and set up the adjusting cylinder 83 on the seat of arranging 1, the push rod of adjusting cylinder 83 links to each other with connecting rod 82, it connects on wheel arrangement frame 81 to wait to detect the wheel rotation, drive wheel 4 can with wait to detect the wheel and lean on.

The driving motor 9 is a speed reduction motor, the diameter of the speed reduction motor is far larger than the diameter of a wheel, torque can be transmitted to the wheel, and the efficiency and the reference basis can be improved by simultaneously detecting a plurality of wheels.

The pressing force between the wheels and the driving wheels 4 is increased or decreased by controlling the adjusting cylinders 83 to simulate different loads of the vehicle.

The cone pulley 6 is close to the cone disc 5 by controlling the hydraulic cylinder 3, so that the cone disc 5 is driven to push the driving wheel 4 to move along the axis direction of the main shaft 2, the wheel is subjected to external force in a non-radial direction, and non-radial acting force formed by feeding back the wheel when the vehicle turns and bumpy road surface is not simultaneously simulated. Because the environment of simulation is more many units, can make the wheel detect more and be close to reality through the cooperation of pneumatic cylinder 3 and adjusting cylinder 83, improve and detect the precision. The arrangement of each sensor in the scheme is the same as that of the prior art.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
