Detailed Description
The invention is described in further detail below with reference to the accompanying drawings:
as shown in fig. 1, the device for observing the oil level of the transmission for the rack of the present invention comprises a supporting block 2 and an oil pipe 3.
Supporting shoe 2 and the equal vertical setting of oil pipe 3 are on base 1, and base 1 is solid cuboid cast iron, and its quality is heavier, can guarantee base 1's stability.
Be provided with the measurement device on oil pipe 3, the measurement device can be the scale of 3 superscripts of oil pipe, also can be scale 4, scale 4 is adopted to this embodiment, 4 vertical settings of scale keep away from one side of supporting shoe 2 at oil pipe 3, there is the rectangle perforating hole at base 1 front end, a be used for fixed scale 4, make its perpendicular to base 1, as shown in fig. 3, be carved with the recess at 4 central authorities of scale, it is fixed with the recess to use solid glue to be close to 4 one sides of scale with transparent plastic oil pipe 3, once paste, follow-up need not independent dismouting, the experimenter can directly read the fluid height through scale 4 of 3 sides of oil pipe.
The other end of oil pipe 3 connects with metal pipe 14 and inserts, the preferred aluminum alloy tubule that adopts of metal pipe 14, aluminum alloy tubule diameter slightly is greater than plastic oil pipe 3, there is 90 crookedness with the aluminum alloy tubule one end that oil pipe 3 connects and inserts, the other end of aluminum alloy tubule forms with the middle hexagonal screwed joint seamless welding who is the through-hole, no oil leakage when making it be connected with the gearbox, the total length is drawn forth to the aluminum alloy tubule and is 30cm, the air can cool off the fluid in the aluminum alloy tubule, avoid the too high and burnout plastic oil pipe 3 of fluid temperature, hexagonal screwed joint is connected with gearbox owner bottom side oil-out.
As shown in fig. 2, a supporting block 2 with a sliding groove 12 is welded at the end of the base 1, in this embodiment, the sliding groove 12 is a T-shaped sliding groove 12, and the T-shaped sliding groove 12 can slide up and down in cooperation with a sliding block 13 with a T-shaped protrusion. The rear end of the sliding block 13 is provided with a T-shaped bulge, the front end of the sliding block is provided with a platform, and the two sides of the sliding block are the top ends of the sliding blocks 13 with the extending lengths of 10 cm. The T-shaped sliding chute 12 can prevent the sliding block 13 from swinging back and forth when the sliding block 13 goes up and down, so that the camera is prevented from shaking, the camera can be placed on a platform at the front end of the sliding block 13, the lens of the camera faces the oil pipe 3 and the graduated scale 4, the camera is directly connected with an upper computer outside a laboratory through a USB (universal serial bus) connection wire, and a damping rubber pad 8 is added between the camera and the platform and is mainly used for damping, because in the laboratory, in the running process of a gearbox, vibration has certain influence on the scale value observation stability of the camera; light in the laboratory is dim and gearbox ambient temperature is too high when reading to fluid height scale value produces the oil mist factor influence, installs two LED lamps 7 on 13 both sides tops of sliding block and observes the light filling, and LED lamp 7 is towards oil pipe 3, promotes fluid observation accuracy.
A square iron plate fixed by bolts is arranged at the top end of the supporting block 2, four legs of a rotating motor 9 capable of rotating forward and backward are fixedly connected with the iron plate through bolts, a wire collecting groove 5 is fixed at the output end of the rotating motor 9, one end of a hanging wire 10 in the wire collecting groove 5 is fixed with a connecting hole on a sliding block 13, the other end of the hanging wire 10 is fixed in the wire collecting groove 5, the hanging wire 10 is wound in the wire collecting groove 5, and the rotation of the rotating motor 9 drives the rotation of the wire collecting groove 5, so that the hanging wire 10 is released or wound and tightened; the control unit box is installed at 2 dorsal parts of supporting shoe, be provided with motor control unit 6 in the control unit box, it is connected with motor control unit 6 to rotate motor 9, and infrared remote controller rotates motor 9 with motor control unit 6 through infrared wireless control and rotates, the experimenter operates infrared remote controller through the glass window outside the laboratory and rotates the forward of motor 9, reverse rotation control, thereby make suspension wire 10 tighten up or release and drive sliding block 13 and slide from top to bottom, then the camera acquires the fluid scale image.
Because rear axle and gearbox oil circuit UNICOM, so the oil filler hole is located the rear axle top, when the experimenter refueled the gearbox, fluid gets into the gearbox from the rear axle, can carry out the observation of main case liquid level through oil pipe 3 that draws, because of present fluid mainly is in the rear axle cavity, treat that the charge adds the demand after, the experimenter starts the engine and idles, at this moment fluid passes through the oil pump oil absorption and gets into the gearbox, the image that the experimenter acquireed at the outer host computer accessible camera of laboratory carries out the oil level scale interval and observes.
When gearbox fluid liquid level descends, the experimenter rotates motor 9 through infrared wireless control and carries out the antiport through pressing infrared remote control button-, receive wire casing 5 and begin slow release suspension wire 10, sliding block 13 then descends slowly, when the camera visual angle aligns with the liquid level scale 4 that corresponds, survey the fluid height value through the host computer, the decline of main tank fluid oil level is comparatively obvious this moment, the liquid level value is if be less than the minimum liquid level height of jet pump in the main tank, the analysis reachs, the phenomenon of taking place to inhale by current gearbox main tank fluid.
For example, when the oil liquid level of the gearbox rises, an experimenter rotates the motor 9 to rotate in the forward direction through infrared wireless control by pressing the infrared remote control button +, and the wire collecting groove 5 starts to slowly tighten the suspension wire 10. Sliding block 13 is then flat ascending slowly, when the camera visual angle aligns with the liquid level scale 4 that corresponds, observes fluid height value through the host computer, and the main tank fluid oil level rises comparatively obviously this moment, and if fluid liquid level is higher than the predetermined height value of main tank fluid, the analysis is derived, and current gearbox main tank fluid can not pass through the jet pump backward flow.
For example, when experimenters test various functions related to hydraulic pressure of the gearbox or the rear axle, the sliding block 13 is lifted and lowered by pressing the infrared remote control button + and the button, and the abnormal phenomena of other oil liquid levels in the gearbox can be indirectly analyzed by observing the oil level change of the gearbox.
