The specific embodiment
Below in conjunction with the description of drawings and the specific embodiment the present invention is explained further details.
Fig. 3 to Fig. 6 is that the structure that the preferred embodiment of the present invention reaches wherein two kinds of different conditions of baffle plate; The front end of the vehicle frame 1 of the trailer of this preferred embodiment is set up on the bogie truck 2 of tractor truck; In order to realize safe and efficient straight line car-backing; Leading flank in the center of the front cross rail 21 of bogie truck 2 is provided with an anchor shaft 81; The middle part of baffle plate 8 is articulated in anchor shaft 81; Drive baffle plate 8 and be arranged on the trailing flank of front cross rail 21 centers of bogie truck 2 around the oil cylinder 6 of anchor shaft 81 rotations, on the front cross rail 11 of vehicle frame 1, be provided with clamping with the correspondence position of baffle plate 8 and hold the registration device of baffle plate 8 to prevent that vehicle frame 2 from freely rotating, this registration device is made up of two two locatings plate 82 that are welded on the front cross rail 11 of vehicle frame 1.Two locatings plate 82 are parallel to be welded on the front cross rail 11 of vehicle frame 1, and on the envelope frame, the inner distance of two locatings plate 82 has formed the opening that limits baffle plate 8 and held baffle plate 8 with clamping more than or equal to the width of baffle plate 8 before also can being welded in.In other embodiments, except oil cylinder 6, cylinder also can be used as and drives the actuating device of baffle plate 8 around anchor shaft 81 rotations; Certainly the hydraulic pipe 67 and the electromagnetic valve 7 that cooperate with oil cylinder 6 also will adjust accordingly, and actuating device also can be electromagnet, and the magnetic that produces during power supply can be with the end absorption of baffle plate; Its other end can rotate around anchor shaft; In other embodiments, the embodiment of registration device also never only limits to be made up of two locatings plate, as long as have the opening that can tighten baffle plate on it; For example can be steel plate or the steel pipe that bends to U-shaped, also can be steel plate that offers gap etc.The oil cylinder 6 of forming actuating device is connected with the hydraulic efficiency pressure system (not shown) through electromagnetic valve 7, is connected with hydraulic pipe 67 between oil cylinder 6 and the electromagnetic valve 7, and electromagnetic valve 7 electrically connects with the master cock (not shown); And master cock is located at (not shown) in the operator's compartment, very convenient like this driver's operation, and the piston rod 62 of oil cylinder 6 is hinged with the lower end of baffle plate 8 through a pipe link 68; Pipe link 68 is affixed with piston rod 62; Hinged with the lower end of baffle plate 8, can shorten the length of piston rod 68 like this, reduce the stroke and the volume of oil cylinder; Be convenient to be placed on the bogie truck 2, also reduced the manufacturing cost of oil cylinder 6.On bogie truck 2, also be provided with a permanent seat 61, oil cylinder 6 is located on this permanent seat 61.
In this preferred embodiment; The vertical section of baffle plate 8 is Z-shaped, and its interlude is shorter, and is approximate right angle with one section the angle that can snap in locating plate 82 through rotation that is attached thereto; With excessively be connected with arc for one section with pipe link 68 pivotallys attached; First flex point of baffle plate 8 is articulated in anchor shaft 81, and the end of baffle plate 8 and pipe link 68 pivotally attached hinge holes 84 are slotted hole, the activity space that the Z-shaped design of baffle plate 8 and the slotted hole of hinge hole 84 design can reduction baffle plate 8 is required; Guarantee piston rod 62 under the situation that level is stretched, the other end of baffle plate 8 rotates.The hinged anchor shaft 81 on it of baffle plate 8 is located on the bogie truck 2 through two otic placodes 83 that are parallel to each other, and two otic placodes 83 are 7 fonts, are positioned at the leading flank of the center of bogie truck 2 front cross rails 21, and the two ends of anchor shaft 81 are divided into the evagination place of two otic placodes 83.Two otic placodes 83 laterally arrange, and the bottom in the space that forms between wherein can be through the pipe link 68 that moves reciprocatingly.
This preferred embodiment can driven in-house operation by the driver when using, the driver is driving indoor start-up control switch control electromagnetic valve 7 before the reversing; Piston rod 62 is stretched out; Piston rod 62 promotes baffle plate 8 forward and upwards rotates around anchor shaft 81, and baffle plate 8 is stuck between two locatings plate 82 on turning an angle afterwards, has limited freely rotating of vehicle frame 2; Thereby realized the straight line car-backing of independent trailer easily, as shown in Figure 5.Reversing finishes the back driver and controls master cock, makes piston rod 62 withdrawals, and baffle plate 8 rotates around anchor shaft 82, and is as shown in Figure 4, vehicle frame 2 rotary state that affranchises.
Can learn from above-mentioned analysis the preferred embodiment of the present invention; When moveing backward; The driver is relatively rotating between may command vehicle frame and the bogie truck at operator's compartment, does not need other auxilian, the mechanism that does not also need M/C control vehicle frame to rotate; The present invention has convenient and swift, safe and reliable advantage when carrying out reverse action.
Yet the above is merely preferred possible embodiments of the present invention, and unrestricted protection scope of the present invention, so the equivalent structure that all utilization descriptions of the invention and accompanying drawing content have been done changes, all is included in protection scope of the present invention.
