Embodiment
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with accompanying drawing, the utility model is further detailed.
As Fig. 2, shown in Fig. 3, for wire testing method under a kind of wheel box parking function that the utility model provides, comprise the following steps: S1: wheel box is adjusted to neutral gear, in setting wheel box, differential mechanism rotating speed is definite value, wherein, wheel box being set to neutral gear object is when preventing test, damage is caused to wheel box, differential mechanism in wheel box is set to definite value, propulsion system can be installed additional realize, in the present embodiment, described differential mechanism rotating speed definite value is the tachometer value higher than differential mechanism during setting speed, described setting speed is the critical rotary speed when wheel box wheel box parking function lost efficacy.
S2: cut off differential mechanism power supply, manual adjustments wheel box parking system park mode, judges whether wheel box parking function lost efficacy.Wherein, manual adjustments wheel box parking system park mode can be and pulls parking handle, is linked into parking shelves, now, if the parking speed of a motor vehicle declines, carries out next step and detects, if the parking speed of a motor vehicle is unaffected, then judge that parking function lost efficacy.
S3: detect differential mechanism rotating speed, convert the rotating speed after detecting to the speed of a motor vehicle by formula V=0.377nr, in formula, n is differential mechanism rotating speed, and r is detected wheel of vehicle radius.According to different automobile types, the parking speed of a motor vehicle is different, and wherein, the setting speed in step S1 also calculates by this formula.
S4: the speed of a motor vehicle of measurement and parking are set the speed of a motor vehicle and compares, judges that whether wheel box parking function is effective.Wherein, critical speed when the described setting speed of a motor vehicle is the inefficacy of wheel box parking function.During test, when the speed of a motor vehicle measured is less than the setting speed of a motor vehicle, judge that wheel box parking function is effective.All the other situations, during as being greater than the setting speed of a motor vehicle or equaling the setting speed of a motor vehicle, judge that parking function is invalid.
Further, before step S1, also comprise and regulate parking system in wheel box to be in N shelves, judge whether wheel box is in neutral gear, if then carry out step S1, then return if not and readjust parking system.
It should be noted that, in step sl, described definite value is higher than setting speed differential mechanism tachometer value, and described setting speed is the critical rotary speed when wheel box wheel box parking function lost efficacy.
The utility model embodiment also disclosed a kind of wheel box parking function and to roll off the production line proving installation, as shown in Figure 1, comprise motor 9, flywheel 8, left connection semiaxis 6, automatic gear-box 4, right connection semiaxis 2 and shaft collar 1 that horizontal direction connects in turn, wherein, described left connection semiaxis is provided with speed probe, and the described speed probe other end connects display dial 10.In the present embodiment, motor 9 is located on motor base, and motor 9 connects on the left of automatic gear-box 4 by flywheel with the left semiaxis that is connected, and left connection semiaxis is transmission input shaft, and right connection semiaxis connects on the right side of wheel box, and the right connection semiaxis other end is fixed on shaft collar 1.
Concrete, differential mechanism 3 is provided with in wheel box, described differential mechanism 3 left end connects left connection semiaxis, and described differential mechanism right-hand member connects right connection semiaxis, and right-hand member is fixed on shaft collar by right connection semiaxis, wherein, left connection semiaxis can rotate with flywheel, and wherein also comprise the parking system 5 be located in wheel box, parking system 5 is connected with output shaft, output shaft is by gear driven differential mechanism 3, and differential mechanism also also connects parking system.
It should be noted that, in described display dial, be preinstalled with single-chip microcomputer, described single-chip microcomputer executive routine, engine speed can be changed into the speed of a motor vehicle and be presented on display dial screen, realizing by formula V=0.377nr.
More specifically, when measuring automatic gear-box parking function, first parking system 5 is set and is in N shelves, hand rotation automatic gear-box 4 differential mechanism end checks whether as neutral position state, if differential mechanism end rotatably, illustrate that now wheel box is in neutral position state, then starter motor 9, motor 9 drives differential mechanism 3 to rotate by flywheel 8 and left connection semiaxis 6, speed probe is fixed on motor base, monitor the rotating speed of left connection semiaxis, by single-chip microcomputer setting program, the left connection semiaxis rotating speed that sensor 7 reads is changed into the car load speed of a motor vehicle that wheel box mates, the speed of a motor vehicle is presented on display dial.Wherein conversion formula: in V=0.377nr formula, n is the rotating speed (rpm) of differential mechanism, and r is the radius of wheel (m) of detected vehicle, in the present embodiment, the radius of wheel that detected wheel of vehicle radius mates for wheel box, V is the car load speed of a motor vehicle (km/h).
Motor loads rotating speed from 0, stabilizing speed is more than certain speed of a motor vehicle of more than b km/h, after reaching, motor 9 stops, differential mechanism 3 relies on the inertia of flywheel to be rotated further, the effect of flywheel is protection motor, under preventing parking operating mode, motor 9 continues accelerate and burn out motor, manual operation parking handle, control realization parking function, park pawl is made to enter in parking gear, until realize parking, record the speed of a motor vehicle c that now display dial 10 shows, the speed of a motor vehicle is now the parking speed of a motor vehicle, if parking speed of a motor vehicle c>b now or c=b, then parking function lost efficacy, if c<b, then parking function realizes successfully.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
