A travel limiting device for a vehicle

Abstract

A travel limiting device for a vehicle, one end of the limiting device is connected to the brake pedal of the vehicle, and the other end is connected to the windshield of the vehicle, the limiting device includes: a pull wire and a limiting assembly; the limiting assembly includes: a revolving body, a gear lever and a block; the gear rod is fastened to the revolving body; the stopper includes: a first working state and a second working state; the present invention provides The unique stroke limit device reduces the error that the driver cannot accurately control the pedal stroke due to the foot feel during the test process. Due to the reduction of the error caused by the pedal stroke, the error between the test results is reduced, and the impact on the test result is reduced. Different degrees of influence of data analysis and processing improve the accuracy of the test; precise control of the brake pedal travel, no movement occurs after reaching a certain position, ensuring the consistency of the test, and avoiding the error of the pedal travel affecting the accuracy of the test results.

Description

technical field [0001] The invention relates to the technical field of field testing of special vehicles, in particular to a travel limiting device for vehicles. Background technique [0002] In the vehicle performance test, precise control of the vehicle speed or throttle opening is required. For example, the braking test requires different vehicle speeds such as the initial braking speed of 100km / h and 60km / h, and the starting performance test requires the control of the throttle opening of 10% and 30%. , 50%, etc., these are corresponding to the stroke of the accelerator pedal; in the ISO7995 turning brake test, it is required to control the vehicle deceleration 0.1g, 0.2g, 0.3g, etc., and the deceleration value is the same as the stroke of the brake pedal corresponding. During the test, the pedal stroke cannot be accurately controlled only by the driver's foot feel, and there will be a large error during manipulation, which requires repeated tests, and the error between...
