Example Embodiment

[0020] The pedal force detector of the present invention is used to detect the force applied to the pedal of a motor vehicle, and the main detection parameters are the change of pedal force and stroke, leakage stroke and time. Such as figure 1 As shown, the overall structure of the present invention includes a housing 4, a transmission device, and a detection mechanism 6. The transmission device is arranged in the housing 4, and the detection mechanism 6 is arranged at the front end of the housing 4, and is connected to the sliding spindle 19 and the sliding spindle 19 of the transmission device in the housing 4. The countershaft 7 is connected.

[0021] The shell 4 is constructed of profiles, and the bottom of the shell 4 is provided with two adjusting feet 5 whose height can be adjusted to be suitable for detecting the pedal force of different vehicle models. The rear end of the housing 4 is connected with a rear end support 3, and the rear end support 3 is fixed to the slide r...

Abstract

A pedal effort detector comprises a shell, a transmission device and a detection mechanism. The transmission device is arranged inside the shell. The detection mechanism is arranged at the front end of the shell and connected with the transmission device. The transmission device comprises a main frame, an auxiliary sliding shaft, a main sliding shaft and a slippage mechanism. The slippage mechanism is installed on the main frame. Both the auxiliary sliding shaft and the main sliding shaft are connected to the slippage mechanism. The detection mechanism comprises a front end base, a front end top plate, a force sensor and a microswitch, wherein the front end base is connected with the main sliding shaft and the auxiliary sliding shaft, the front end top plate is installed on the front end base, a spring is arranged between the front end top plate and the front end base, the force sensor, a floating shaft and the microswitch are installed inside the front end base, and the floating shaft is connected with the front end top plate. According to the detector, parameters such as force applied to a vehicle braking system pedal, displacement generated on the vehicle braking system pedal, and time spent by operating the vehicle braking system pedal are collected in real time through the force sensor, the safe quality performance of the vehicle braking system is reflected, the measured data are accurate, and operation is easy and convenient.

Description

technical field [0001] The invention relates to an instrument for detecting the sealing performance and filling quality of an automobile brake system, and belongs to the technical field of brake pedal force detection. Background technique [0002] Evaluation and measurement of vehicle braking force is an important part of motor vehicle safety performance testing. In the process of automobile manufacturing, the brake system generally adopts the process of vacuuming and pressure filling, but there is no intuitive data for reference on the sealing performance and filling quality of the brake system. [0003] At present, the brake performance test method used by most domestic and foreign automobile manufacturers is the roller reaction brake test bench. It is composed of two sets of symmetrical wheel braking force test units and a set of indicating and controlling devices with the same structure. Each set of wheel braking force test unit is composed of frame, driving device, ro...
