Description
Technical field
The utility model relates to a kind of automobile vibration test and uses equipment, especially relates to a kind of motor turning disc vibration testing auxiliary device.
Background technology
The automobile vibration test is in order to estimate a kind of basic skills of vehicle safety performance; Through to the motion state of in-vehicle apparatus in the car in the automobile vibration test and the analysis of the situation of injury, set up or improve passenger's in the car safety guard, improve the security of vehicle structure design; Protect passenger safety better; Vibration-testing to the motor turning dish is like this equally, and vibration of steering wheel directly has influence on driver's ability of controlling to steering wheel in vehicle traveling process, and excessive vibration also can exert an influence to vehicle traveling direction; So will be in accurate recording vibration of steering wheel characteristic in the motor turning disc vibration test, design provides reliable foundation to vehicle; The main box-like accelerometer that adopts of motor turning disc vibration test at present; Accelerometer only adopts straightforward procedure such as being bonded on the steering wheel with glue, adhesive sticker etc. in test process, and accelerometer can only approximately contact near line with steering wheel, and measurement data is inaccurate; Moreover on steering wheel, can stay the glue impression; Can destroy when serious and turn to the plate wheel outer cover, under the situation that the accelerometer profile can't be changed, should adopt off-line equipment degree of will speed up meter and steering wheel to be fixed up.The Chinese patent document has been announced " a kind of rotation angle of automotive steering wheel pick-up unit ", and its Granted publication number is CN 201206977 Y, and Granted publication day is on March 11st, 2009; It provides a kind of pick-up unit, through obtaining the kinematic parameter of vehicle steering steering column shaft, detects the rotational angle of vehicle steering; Comprise: pick-up unit, engaged wheel assembly, driving wheel and driving-belt; Described driving wheel is located on the steering column shaft, and driving wheel is connected with the engaged wheel assembly through driving-belt, and the motion of steering column shaft is passed to the engaged wheel assembly; And the axis parallel of engaged wheel assembly and driving wheel; Described pick-up unit is located on the engaged wheel assembly, through obtaining the kinematic parameter of engaged wheel assembly, detects the rotational angle of vehicle steering.This scheme can be used for detecting the rotational angle of vehicle steering, but its structure can't be used for vibration-testing.
The utility model content
The utility model is for the fixing not good problem of accelerometer in the motor turning disc vibration test that overcomes prior art, provides a kind of and can well secured be provided to accelerometer, and be fixed as the fixing steering wheel vibration-testing servicing unit of face with steering wheel.
To achieve these goals, the utility model adopts following technical scheme: a kind of steering wheel vibration-testing servicing unit comprises accelerometer; Also comprise holder; Described holder is a rectangular configuration, and the holder bottom surface is the cambered surface that caves inward, and cambered surface is provided with groove; Holder is fixed on the steering wheel, and described accelerometer is fixed on the holder end face.Through a holder as the transition erecting device between accelerometer and the motor turning dish; Can solve the fixing not good problem of accelerometer preferably; Holder can adopt resilient material to make the cuboid structure, and the bottom surface that holder contacts with steering wheel cooperates with circular steering wheel and is made as cambered surface, and a groove more smaller than steering wheel wheel diameter is set on cambered surface again; Adopt the resilient material can be turning to plate wheel to stick in the groove like this such as the holder of rubber etc.; And because the restriction of shape, holder groove and turning between the plate wheel can not rotate, and accelerometer then can arbitrarily be fixed on the end face of holder; Thereby all can realize fixedly contacting of face and face between holder and steering wheel, accelerometer and the holder, during vibration-testing vibration data accurately can be provided.
As preferably, described holder end face is provided with boss, the holder end face be provided with and end face with long elongated slot, elongated slot connects the boss bottom, described accelerometer is fixed on the boss.Utilize groove to block steering wheel; Holder sometimes can produce along the cylindrical that turns to plate wheel and move; If can destroy turning to the plate wheel outer cover to produce with the holding screw location, be used for fixing accelerometer so a boss is set on the end face of holder, and the elongated slot long together with end face of a perforation boss bottom is set on end face again; Use soft article such as bandage to pass elongated slot, holder is bundled in turns on the plate wheel.
As preferably, described holder is provided with from the expansion joint of groove middle part to holder end face, and the holder side is provided with fastener hole.Usually the diameter of wheel body of motor turning plate wheel own is also inconsistent; The words that a groove only is set on the holder can not obtain versatility; So on holder, be divided into two groove with a expansion joint from groove middle part to holder end face; The size of groove can change under the effect at expansion joint like this; With the motor turning plate wheel that fit diameter differs, release place of stroke when holder end face elongated slot then can stretch as the expansion joint, and holder can the mode with bolted clamp in the holder side with turning to the fixing of plate wheel.
As preferably, be provided with cushion in the groove of described holder.When holder clamped with the mode that turns to the fixedly employing bolted of plate wheel, strength was bigger when tightening owing to bolt, made holder so the cushion that flexible material is made can be set in the holder groove, to avoid crushing turning to the plate wheel outer cover to crush.
Therefore, the utlity model has following beneficial effect: (1) holder with turn to the face of being fixed as of plate wheel to fix; (2) accelerometer is fixed well at holder.
