Abstract
The utility model relates to an automotive transmission gap measurement apparatus, which belongs to the performance detection technology of an automobile. The automotive transmission gap measurement apparatus is mainly composed of a mechanical supporting rod with a through slot, a screw rod with a forward screw thread and a reverse screw thread, two movable clamp jaws and a detection box. the two movable clamp jaws are arranged on the screw rod with the forward screw thread and the reverse screw thread. The screw rod with the forward screw thread and the reverse screw thread is arranged in the through slot of the mechanical supporting rod. When the screw rod is rotated, the two movable clamping jaws can move in opposite directions, and thereby, a detector is fixed on a propeller shaft to realize the detection. The detection box is provided with an angle encoder and a processing circuit. When the detector is rotated along with the propeller shaft, the clearance of the propeller shaft can be detected through the detection box.
Description
The utility model belongs to the automotive performance detection range.
To the automotive transmission gap, there is its relevant required standard in country, but the instrument that detects the whole drive unit gap does not at present also have, and has only the instrument that detects transmission shaft gap in the automotive transmission, and does not detect the instrument in the gap and the retarder gap of each gear variable gear of automobile.The instrument in existing detection transmission shaft gap is such: detector is mainly by detecting box and locking belt and form.Detect in the basin angular transducer is housed.Its method of inspection is to use the locking belt to be wound on the propeller-shaft, makes to detect to connect firmly motionlessly between box and the propeller-shaft, with the hands holds propeller-shaft then and rotates, and detects the transmission shaft gap length by angular transducer.The shortcoming of this detector is that (1) test item is single, can't realize detection to the whole gaps of automotive transmission, promptly can not detect change speed gear box gap and drop-gear box gap,, can not satisfy the related standards of Ministry of Communication so can't judge the quality of each position performance of transmission system.(2) detect effort.Because be that the manpower rotating drive shaft detects, so it is many to expend muscle power.
The purpose of this utility model is: the automotive transmission gap detection instrument that a kind of automotive transmission of complete detection fast and accurately gap is provided.
The purpose of this utility model is to realize like this, accompanying drawings is as follows: automotive transmission gap detection instrument is made up of clamping body and detection box, clamping body wherein comprises the mechanical pole 3 that has groove, screw rod 5 with forward and reverse screw thread is housed in the groove, two movable jaws 2,6 are contained in the forward screw thread and the reverse thread place of screw rod 5 respectively, the prolongation of screw rod 5 is a dowel bar 7, the one end is a turn-knob 10, one end of machinery pole 3 is a bar handle 9, be connected with force transducer 8 between machinery pole 3 and the bar handle 9, be equipped with on the mechanical pole 3 and detect box 11.
The utility model has changed the detection mode of moving propeller-shaft with hand, tighten the transmission shaft universal-joint and use detector instead, mode with the hand operation detector is measured, can detect the gap at each position such as change speed gear box in the transmission system, transmission shaft and retarder like this, for automobile failure diagnosis provides theoretical foundation.In addition, can also detect the required moment size in elimination gap by force transducer.Thereby the present situation that has changed that there is diagnostic criteria in Ministry of Communication to the automotive transmission situation and can't detecting device.
Further specify particular content of the present utility model and working process below in conjunction with the accompanying drawing illustrated embodiment.
Fig. 1 is according to the automotive transmission gap detection instrument structural representation that the utility model proposes;
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Among the figure: 1. plug 2. movable jaws 3. mechanical pole 4. locating pieces 5. screw rods 6. movable jaws 7. dowel bars 8. force transducers 9. bar handles 10. knobs 11. detect box 12. treatment circuits 13. angular encoders
Have oblong channels in the machinery pole 3, in screw rod 5 with forward and reverse screw thread is housed, two movable jaws 2 and movable jaw 6 are housed at the screw thread place, the prolongation of screw rod 5 is that knob 10 is equipped with in the end of drive link 7, when turning knob 10, screw rod 5 rotates thereupon, and the movable jaw 2 and 6 on it moves in opposite directions, is clamped on the universal-joint of transmission shaft.End mechanical pole 3 is fixed with detection box 11 and bar handle 9, detects in the box 11 angular encoder 13 and treatment circuit 12 and read-out are housed, and after the treated processing of circuit of detection signal, testing result shows on the read-out that detects on the box 11.Bar handle 9 is used for handling the detection of detector realization to each gap, position of transmission system.Plug 1 is contained in the end of mechanical pole 3, and locating piece 4 is used for the axial location of screw rod 5, and force transducer 8 is contained on the mechanical pole 3, and connects with bar handle 9.Working process with this instrument detecting is: at first movable jaw 2 and 6 is stuck in the universal-joint place of transmission shaft, rotation turn-knob 10 makes movable jaw 2,6 chucking transmission shafts, thereby this instrument and transmission shaft is fixed.Move handle on the mechanical pole 3 with hand then, detector rotates with transmission shaft, and angular encoder 13 can detect the transmission shaft rotational angle.When automobile hangs up different gear, having or not under two kinds of situations of brake, the gap of automotive transmission different parts can be detected, and the required moment size in elimination gap can be detected by force transducer 8.
