Abstract
The utility model relates to a detector for the pedal path and the pedal force of an automobile. The utility model comprises a stationary sleeve barrel and a movable sleeve barrel which can move mutually, wherein, a meter is arranged at the upper end of the stationary sleeve barrel. A zero-adjusting turn button and a microcomputer interface are arranged on the meter, and a pedal force sensor is arranged at the end part of the movable sleeve barrel. A hook is arranged on the wall of the stationary sleeve barrel and can be adjusted up and down, and a displacement sensor is arranged between the stationary sleeve barrel and the movable sleeve barrel. After a test signal of the utility model is processed by a signal processing part, by using the microcomputer interface, the test value can be displayed on a dashboard and can form network interconnection with a microcomputer. When the utility model is used, the pedal force, the free path, the total path and the braking slowing value of a clutch and a brake can be conveniently and accurately detected.
Description
Automobile pedal travel and pedal force detector belong to the automotive performance detection range.
Auto pedal power and pedal travel (comprising two on clutch coupling and detent) are the key character parameters of estimating clutch coupling and brake performance.Pedal force is crossed the labour intensity that senior general increases the driver.Free play of clutch is excessive or too small, will cause clutch coupling combination reliably or thoroughly separation.The brake pedal free travel is excessive or too small, will cause braking ineffective, and the braking return is thorough etc.At present, reasonably auto pedal power and pedal travel are guaranteed that by manufacturer still, behind the certain mileage of running car, these parameter values all will change.For recovering rational auto pedal power when the motor vehicle repair and pedal travel provides foundation, the measurement of common employing ruler realizes that its shortcoming is that means fall behind, and measures time-consumingly, and error is big, is difficult to meet the demands.
The purpose of this utility model is to provide a kind of automobile pedal travel and pedal force detector replacing the ruler hand dipping, with ensure fast, convenient, accurately measured automobiles pedal force and pedal travel, a kind of advanced person's checkout equipment is provided for motor vehicle repair.
The purpose of this utility model accompanying drawings is as follows: this detector is to be grouped into by mechanical part and signal processing part, said mechanical part is by fixed muffle 3, quill 2, sensor, instrument 6 is formed, quill 2 is sleeved in the fixed muffle 3, and can move mutually, but the hook 5 of up-down adjustment is housed on fixed muffle 3 walls, fixing by wing nut 4, one end of quill 2 is equipped with pedaling force sensor, instrument 6 is contained in an end of fixed muffle 3, instrument 6 is provided with zeroing knob 7 and microcomputer interface 8, displacement transducer is contained between fixed muffle 3 and the quill 2, its test signal shows test value on panel board after the signal processing part divisional processing.
The course of work of this detector as shown in Figure 2, snap ring is hung on the bearing circle, pedaling force sensor is contained on clutch pedal or the brake pedal, after legpower is applied on the pedal, convert pedal force and stroke value to electric signal by pedaling force sensor and displacement transducer, through amplifier and A/D converter, finally on instrument, show test value, test signal to the V/I converter, finally enters computing machine through amplifier, realizes the computer data transmission.
That this detector has is simple in structure, compact, easy for installation, test accurately, directly perceived, the working stability of reading, and can and microcomputer network.
Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.
Fig. 1 is the structural representation according to the auto pedal detector that the utility model proposes.
Fig. 2 is the fundamental diagram of this detector.
Describe in detail according to concrete detection details and the working condition only that the utility model proposes below in conjunction with accompanying drawing.
This detector comprises a fixed muffle (3), and hook (5) is housed on it, and this hook (5) can be gone up its position of upper and lower adjusting at fixed muffle (3), and available wing nut (4) is fixing.Instrument (6) is equipped with in the upper end of fixed muffle (3), zeroing knob (7) and microcomputer interface (8) are housed on the instrument (6), can show clutch-pedal load, free travel, total kilometres and brake pedal power, free travel, total kilometres on the dial plate of instrument (6).Quill (2) is housed in the fixed muffle (3) can be moved between them mutually, one end of quill (2) is equipped with pedaling force sensor, retracing spring and displacement transducer are housed between quill and fixed muffle, its test signal shows test value through microcomputer interface on instrument after the signal processing part divisional processing.
Said signal processing is force transducer and displacement transducer test signal to be amplified back one tunnel through amplifier show test value through A/D converter on instrument, and another road is changed through V/I and sent into computing machine.
The test process of this detector is: detector is passed bearing circle, the pedaling force sensor of quill one end is placed on clutch pedal or brake pedal top, regulate hook (5) according to different automobile types, hook (5) is clipped on the bearing circle, and screw wing nut (4), make fixed muffle play downwards.Zeroing knob on the regulation meter then, making the instrument show state is 000.When foot pedals was felt resistance is arranged, the height of pedal promptly demonstrated reading on instrument, and this reading is the free travel value of pedal.When pedal is continued to step on downwards to extreme position, at this moment, the reading of instrument is the total kilometres of pedal.After measuring the brake pedal total kilometres, pedal was kept three minutes at extreme position, at this moment, the changing value of instrument is the slow value of letting out of braking.If send to computing machine, after measuring each, press the clutch coupling free travel and the total kilometres soft-touch control of this instrument and meter respectively, or the gentle soft-touch control of letting out of detent free travel, total kilometres, or the gentle soft-touch control that swings of detent free travel, total kilometres, the data result that is about to above-mentioned measurement imports microcomputer into.In the testing process of free travel, the numerical value of pedal force directly is presented on the instrument, and as required, the pedal force size of being tested is by pressing transmit button, and test number can reach microcomputer.
Claims (2)
1. automobile pedal travel and pedal force detector are to be grouped into by mechanical part and signal processing part, it is characterized in that said mechanical part is by fixed muffle (3), quill (2), sensor, instrument (6) is formed, quill (2) is sleeved in the fixed muffle (3), and can relatively move, be equipped with and go up on the fixed cover barrel, the hook of following adjusting (5), fixing by wing nut (4), one end of quill (2) is equipped with snap ring (1), pedaling force sensor is contained in snap ring (1) and locates, instrument (6) is contained in an end of fixed muffle, instrument (6) is provided with zeroing knob (7) and microcomputer interface (8), retracing spring and displacement transducer are installed between fixed cover letter (3) and the quill (2), its test signal shows test value on panel board after the signal processing part divisional processing.
