After the sideslip performance test is finished, closing the driving mechanism 5, opening the ball valve 31 in the oil return pipeline 18, and directly flowing hydraulic oil in the side-push hydraulic cavity 22 and the side-push branch pipeline 19 into the hydraulic oil cavity 14 through the oil return pipeline 18; the ball valves 31 in the return line 18 and the side branch line 19 are then closed, and the ball valve 31 on the left side of the side branch line 19 is opened. And when the driving mechanism 5 is restarted, the hydraulic oil in the hydraulic oil chamber 14 enters the ejection hydraulic chamber through the oil supplementing pipeline 16, the hydraulic cylinder 15, the oil inlet pipeline 17 and the ejection branch pipeline 20, and the second plug plate 28 is pushed, so that the ejection frame 30 supports the chassis of the automobile and ejects the automobile. And then the height of the automobile wheel is determined according to the distance from the automobile wheel to the automobile speed and the distance from the brake testing device. The distance between the sleeve 51 and the wheel hub bolt is adjusted by rotating the first threaded rod 35 with a wrench to slide the slide block 34 along the slide slot 33 towards the wheel. Then, the threaded cylinder 38 is rotated, the threaded column 37 in threaded connection with the threaded cylinder 38 tends to rotate upwards, and the limiting strip 72 fixedly connected with the lower part of the threaded column 37 is in sliding connection with the strip-shaped limiting groove 71 on the inner wall of the sliding cylinder 36, so that the threaded column 37 only ascends but cannot rotate, and the purpose of adjusting the height of the sleeve 51 is achieved. By rotating the second threaded rod 49, the second threaded rod 49 rotates to drive the first toothed block 45 in threaded connection to slide along the first rack groove 43, the first toothed block 45 slides to enable the engaged central gear 42 to rotate, the central gear 42 rotates to drive the other two first toothed blocks 45 engaged with the central gear to synchronously slide along the first rack groove 43, when the first toothed block 45 slides, the helical rack 48 at the upper end of the first toothed block 48 enables the engaged second toothed block 46 to synchronously slide along the second rack groove 44, and when the second toothed block 46 slides to enable the fixedly connected sleeve 51 to synchronously move in a direction away from the center of a circle, so that the tires with different distances from the hub bolt to the center of the hub can be adapted. The distance between the sleeve 51 and the tire, the height of the sleeve 51 and the distance between the sleeve 51 and the center of the rotating disk 41 are finely adjusted until all the sleeves 51 are able to capture the hub bolts, at which point the tire is concentric with the rotating disk 41. When the automobile is started, the wheels rotate to drive the rotating disc 41 to rotate through the sleeve 51, when the rotating bar 50 wrapped with the sensing medium 52 rotates for one circle, the sensing counter 53 is fixedly connected to the upper surface of the base 32 to count twice, and finally, the counting frequency of the sensing counter 53 in unit time is counted for one half to obtain the automobile speed. Then, the automobile is braked, and the acceleration of the wheels is calculated through the induction counter 53, so that the braking performance of the automobile can be obtained.
As an embodiment of the present invention, a through groove 54 is provided on the left side of the hydraulic oil chamber 14 at the lower portion of the hydraulic oil tank 4. During operation, the through groove 54 can communicate the left and right hydraulic chambers 14 without interfering with the operation of the oil inlet pipe.
As an embodiment of the present invention, a diameter of a portion of the oil supply pipe 16 close to the hydraulic cylinder 15 is larger than a diameter of a portion far from the hydraulic cylinder 15, and a diameter of a portion of the oil supply pipe 17 close to the hydraulic cylinder 15 is smaller than a diameter of a portion far from the hydraulic cylinder 15.
As an embodiment of the invention, the section of the oil supplementing pipeline 16 and the section of the oil inlet pipeline 17 with larger diameters are internally provided with the flow stopping balls 55, and the diameter of each flow stopping ball 55 is larger than the diameter of each oil supplementing pipeline 16 and the diameter of each oil inlet pipeline 17. When the hydraulic cylinder 15 works, when the pressure in the hydraulic cylinder 15 is reduced, hydraulic oil in the oil inlet pipe flows into the hydraulic cylinder 15, the flowing hydraulic oil wraps the flow stopping ball 55 to block the oil inlet pipeline 17, and the hydraulic oil in the oil inlet pipeline 17 is prevented from flowing into the hydraulic cylinder 15 in time; when the hydraulic oil in the hydraulic oil chamber 14 flows into the hydraulic cylinder 15 through the oil supply pipe 16, the flowing hydraulic oil will blow open the check ball 55 blocking the oil supply pipe 16, so that the hydraulic oil can flow into the hydraulic cylinder 15 smoothly. When the pressure in the hydraulic cylinder 15 rises, the hydraulic oil in the hydraulic cylinder 15 flows into the oil inlet pipeline 17 and the oil supplementing pipeline 16, and the hydraulic oil flowing into the oil inlet pipeline 17 can flush the flow stopping ball 55 blocking the oil inlet pipeline 17, so that the hydraulic oil can smoothly enter the side thrust pipeline 19 or the thrust branch pipeline 20 through the oil inlet pipeline 17; the hydraulic oil flowing into the oil supply pipe 16 will block the oil supply pipe 16 by the flow stopping ball 55, and the hydraulic oil will be prevented from flowing back into the hydraulic oil chamber 14.
As an embodiment of the present invention, a side of the section of the oil supply pipe 16 with a larger diameter close to the hydraulic cylinder 15 and a side of the section of the oil inlet pipe 17 with a larger diameter far from the hydraulic cylinder 15 are both fixedly connected with a limit rod 56. When the hydraulic oil pump works, when the hydraulic oil flushes the flow stopping ball 55 in the oil supplementing pipeline 16 or the oil inlet pipeline 17, the limiting rod 56 can prevent the flow stopping ball 55 from moving too far, so that the travel of the flow stopping ball 55 wrapped back is too long, and the flow stopping effect is reduced.
As an embodiment of the present invention, the ball valve 31 includes a valve ball 57, a first valve rod 58, a second valve rod 59 and a holding rod 60, the first valve rod 58 is fixedly connected with the valve ball 57, and the second valve rod 59 is fixedly connected with the holding rod 60; the upper portion of the first valve rod 58 is provided with a regular hexagon chute 61, the lower end of the second valve rod 59 is fixedly connected with a cylindrical rod 62, the lower end of the cylindrical rod 62 is fixedly connected with a regular hexagon slider 63, and the regular hexagon slider 63 is connected with the regular hexagon chute 61 in a sliding manner. When the valve is in operation, the rotating holding rod 60 can drive the first valve rod 58 and the valve ball 57 to rotate through the regular hexagonal slider 63, so as to control the opening or closing of the ball valve 31.
As an embodiment of the present invention, the diameter of the cylindrical rod 62 is smaller than the diameter of the regular hexagon inscribed circle of the regular hexagon chute 61. In operation, the second valve rod 59 needs to be pulled upwards for a certain distance before the holding rod 60 is rotated, and the design can prevent the regular hexagon sliding block 63 from being separated from the regular hexagon sliding groove 61.
In an embodiment of the present invention, the second valve rod 59 has a first annular groove 64 formed in a wall thereof, a first spring fixing ring 65 rotatably connected to the first annular groove 64, a second annular groove 66 formed in an upper end surface of the hydraulic oil tank 4, a second spring fixing ring 67 rotatably connected to the second annular groove 66, and a spring 68 disposed between the first spring fixing ring 65 and the second spring fixing ring 67 and fixedly connected to both ends of the spring 68. The upper part of the outer wall of the second valve rod 59 is fixedly connected with an insert rod 69, the insert rod 69 is inserted in an insert hole 70, and the insert hole 70 is arranged at the upper part of the hydraulic oil tank 4; each plug 69 cooperates with two of the sockets 70 and the two sockets 70 are arranged at right angles around the first valve shaft 58. During operation, the insertion rod 69 and the insertion hole 70 are matched to prevent the first valve rod 58 from naturally rotating during non-manual operation, so that the flow direction of hydraulic oil is out of control; the insertion hole 70 is distributed around the first valve rod 58 in a right angle manner, so that only two positions of the ball valve 31 can be fixed, the opening degree of the ball valve 31 is one hundred percent in one position, and the opening degree of the ball valve 31 is zero in the other position; the presence of the spring 68 constantly tightens the first spring fixing ring 65 and the second spring fixing ring 67, preventing the second valve rod 59 from easily sliding and therefore the inserted rod 69 from easily coming out of the insertion hole 70; the first spring fixing ring 65 and the second spring fixing ring 67 are respectively connected with the first annular groove 64 and the second annular groove 66 in a rotating mode, so that the spring 68 cannot rotate to a large extent when the ball valve 31 rotates, and the spring 68 can be adjusted to twist to a small extent conveniently.
According to one embodiment of the present invention, the inner wall of the sliding barrel 36 is symmetrically provided with strip-shaped limiting grooves 71, the lower portion of the threaded post 37 is symmetrically and fixedly connected with limiting strips 72, and the limiting strips 72 are slidably connected with the strip-shaped limiting grooves 71. In operation, when the threaded cylinder 38 is rotated, the threaded post 37 only rises or falls without rotating, and the centering rotary mechanism 40 is prevented from rotating around the sliding cylinder 36.
In one embodiment of the present invention, the upper end of the slide cylinder 36 is provided with a third annular groove 73, the lower end of the threaded cylinder 38 is fixedly connected with a rotating ring 74, and the rotating ring 74 is rotatably connected with the third annular groove 73.
