Vehicle-mounted test device for detecting reliability of forklift pedal mechanism

Abstract

The invention provides a vehicle-mounted test device for detecting reliability of a forklift pedal mechanism. The vehicle-mounted test device comprises a support, a force application mechanism is connected at the top end of the support and comprises an air cylinder support movably connected at the top end of the support, an executing air cylinder is fixedly arranged on the air cylinder support, an induction magnetic ring is arranged in the executing air cylinder, two limit electromagnetic switches are arranged outside the executing air cylinder, an end of a piston rod of the executing air cylinder is connected with a spindle of a wheel, the wheel is arranged in a groove in a rail plate and rolls in the same, a rod cavity and a rodless cavity of the executing air cylinder are connected with two air outlets of an electromagnetic reversing valve respectively through air pipes, and the limit electromagnetic switches are connected with the controller respectively through cables. The vehicle-mounted test device is detachable and is mounted on the forklift pedal mechanism for detecting, so that the pedal mechanism is tested under the condition closest to the actuality, detecting accuracy is improved and reliability of a forklift brake system is guaranteed.

Description

technical field [0001] The invention relates to a test device, in particular to a vehicle-mounted test device for testing the reliability of a forklift pedal mechanism. [0002] Background technique [0003] The forklift braking system mainly applies the braking force to the brake master cylinder through the brake pedal mechanism, so that the outlet generates a liquid flow with a certain pressure, and finally transmits to the brake cylinder through the pipeline. The brake cylinder generates thrust to push the brake shoe. Open to both sides, the shoe is close to the brake hub to generate braking force. Since the braking system is related to driving safety, it is necessary to detect the braking system. [0004] At present, there is no test standard for the pedal system test in the forklift industry. If such a test is to be carried out, it can only be tested by referring to the "Automobile pedal device performance requirements and bench test methods". However, the bench test...

Problems solved by technology

However, the bench test not only requires a large cost to process the test bench, but also the bench test cannot truly reflect the force of the pedal system on the entire vehicle

At present, the reliability test of the pedal mechanism is still limited to the test bench. Although the test on the test bench has the characteristics of easy observation and convenient replacement of samples, it also has the disadvantages that it cannot fully simulate the working conditions, and the installation of auxiliary mechanisms is difficult. Disadvantages such as high cost
