DETAILED DESCRIPTION

[0018] The utility model is further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the utility model and are not used to limit the scope of the utility model. In addition, it should be understood that after reading the content taught by the utility model, those skilled in the art can make various changes or modifications to the utility model, and these equivalent forms also fall within the scope defined by this application.

[0019] like Figure 1-4 As shown, the thrust rod performance tester of the utility model comprises a base 1, which is used as the installation position of various components of the device. A pair of slide rails 11 are arranged in the middle of the base 1, and a detection seat 2 is slidably arranged on the slide rails 11, and the detection seat 2 is a C-shaped structure. A receiving seat 3 is rotatably arranged in the detection seat 2, and the receiving seat 3 serves as the installation position of the front end of the thrust rod.

[0020] A main mounting seat 4 is arranged at the front end of the base 1, and a main actuator 5 is installed on the main mounting seat 4. The main actuator 5 is used to push the detection seat 2 to provide pressure for the thrust rod test installed thereon. An articulated seat 6 is arranged at the rear end of the base 1, and an installation frame 7 is rotatably arranged on the articulated seat 6. The installation frame 7 serves as the installation position of the front end of the thrust rod. Specifically, the installation frame 7 cooperates with the receiving seat 3, and can be used to install both a straight thrust rod and a V-shaped thrust rod, so as to adapt to the detection of both straight thrust rods and V-shaped thrust rods. The main actuator 5 is a hydraulic cylinder, and the middle part of the main actuator 5 is hinged to the main mounting seat 4, and the front end of the piston rod of the main actuator 5 is fixedly connected to the detection seat 2. The main actuator that can output 25 tons of pressure is installed on the base, and can output a load of 18 tons and 3Hz, which is used to simulate the driving force and braking force of a heavy truck.

[0021] A secondary mounting seat 8 is arranged at the rear side of the articulated seat 6, and a side-effecting device 9 is articulated at the top of the secondary mounting seat 8. The front end of the side-effecting device 9 is articulated with the mounting frame 7, and a thrust rod is detachably installed between the receiving seat 3 and the mounting frame 7. Specifically, the mounting frame 7 is a square frame, and a top articulated seat 73 is arranged at the top of the mounting frame 7. The middle part of the side-effecting device 9 is articulated with the secondary mounting seat 8. The side-effecting device 9 is a hydraulic cylinder, and the front end of the piston rod of the side-effecting device 9 is articulated with the top articulated seat 73. Through the extension action of the side-effecting device 9, the mounting frame 7 can be driven to rotate at a certain angle, so as to simulate the torsional swing angle and torque generated when the axle jumps up and down.

[0022] Specifically, the auxiliary mounting seat 8 extends obliquely upward from one end of the hinge seat 6 at a certain angle to provide space for the installation of the auxiliary device 9.

[0023] Specifically, a plurality of mounting holes 71 are arranged in an array at the top and bottom of the rear side of the mounting frame 7, and a pair of matching seats 72 are arranged on the mounting frame 7, and the matching seats 72 are detachably connected to the mounting holes 71 through fastening bolts. With this structure, the distance between the two matching seats 72 can be adjusted, thereby meeting the installation and detection of straight thrust rods and V thrust rods of different sizes.

[0024] Through the above structural design, this patent can simulate to the maximum extent the superimposed stress state of the driving force, braking force, torsion caused by jumping, etc. that the thrust rod is subjected to in the actual vehicle state.

[0025] The 25-ton main actuator 5 is installed on the base 1 and can output a load of 18 tons and 3Hz to simulate the driving force and braking force of a heavy truck. The 3-ton auxiliary actuator 9 can generate a load of 2 tons and 3Hz to simulate the torsional swing angle and torque generated when the axle jumps up and down. When the test piece is installed on the test machine through the additional installation tool, the test machine hydraulic station and control box power are turned on, and the required load or displacement, swing angle, and frequency parameters are input through the touch screen computer set in the electric control box of the test machine to start the test machine. The push and pull of the auxiliary actuator 9 generates swing, which can realize the swing of the rubber core at both ends of the simulated thrust rod when the axle jumps up and down.
