Automobile pedal operating mechanism assembly performance test board

Abstract

The invention discloses an automobile pedal operating mechanism assembly performance test board which comprises a measuring mechanism, a rotary movement mechanism, a transverse movement mechanism, an elevating movement mechanism, a vertical movement mechanism, a support and a data acquisition control system. The support is erected with the vertical movement mechanism. One side of the vertical movement mechanism is provided with the transverse movement mechanism. A top of the transverse movement mechanism is provided with the elevating movement mechanism. The elevating movement mechanism is fixedly provided with the rotary movement mechanism. A top of the rotary movement mechanism is provided with the measuring mechanism. A force transducer of the measuring mechanism is electrically connected with the data acquisition control system. The test board has four degrees of freedom, and can carry out a plurality of detection needed by a pedal such as stroke detection, pedal force detection, output force characteristic detection, elevating time detection, master cylinder pressure characteristic detection, endurance performance detection, actuator head adjusting detection and the like, an exploitation trial-production period of the automobile pedal is shortened, and the test cost in an exploitation process is saved.

Description

technical field [0001] The invention relates to an automobile detection device, in particular to an automobile pedal operating mechanism assembly performance test bench. Background technique [0002] The automobile foot pedal control mechanism assembly is an important part of the automobile chassis. The assembly mainly integrates three foot-operated control mechanisms such as the clutch pedal, the brake pedal, and the accelerator pedal. It is the main part of the driver's control of the vehicle. It is an important human interaction component in the vehicle chassis besides the steering system. The rationality, ease of control and stability of the design of the automobile pedal control mechanism assembly are directly related to the safety, comfort and controllability of the vehicle. The development of the automobile pedal control mechanism assembly with excellent performance and good reliability is the An important topic in vehicle chassis design. [0003] In the research an...
