(57) Abstract:The invention relates to vehicles and can be used as a trailer attachment. The vehicle includes a frame, a front steering wheel, side support wheel, walking mover with a pair of bearing abutments and trailer bracket, which is connected to the frame through the drive mechanism. The cross propeller mechanism used two adjacent hinge, which are rigidly interconnected by a rod. One of the hinges rigidly connected to the frame, and the second hinge is connected with the trailer bracket, in which there is located perpendicular to the axis of the hole for connection with the pin drawbar hitch. The invention is aimed at reducing the overturning moment forces due to the receipt of the imaginary hinge directly on the ground level. 3 Il. The invention relates to vehicles and can be applied as an attachment to ageusia vehicle.In known systems of the hinge of the hinged rotation of the frame of the vehicle relative to the drawbar hitch above the ground clearance on an axis located at the level of the trailer bracket that abuseable the VA is stepping vehicle under the patent of USSR N 3221, B 62 D 57/032, 1927, It contains the frame, the steering wheel and walking mover with a pair of bearing abutments. This vehicle point of engagement of the abutment toe when walking motion is moved relative to the frame, which changes the length of the shoulder tipping back torque thrust MFand balancing torque weight MP. For example, it looks like this /see Fig. 1/. Let the power of the weight of the walking vehicle applications including But support foot has engaged in T. B., frame, so In geared cargo, Measured in millimeters length shoulder A B1, A B2and B'1B1B'2B2find how many times determines the stability of the vehicle, the ratio of the moments MP/MFto the rear support feet will be bigger than the front.MP1/MF1= A B1/B1B1P/F = 10/40 P/F = 1/4 P/F,
MP2/MF2= A B2/B2B2P/F = 50/18 P/F = ,8 P/F,
2,8/0,25 = 11.Thus, the disadvantages of the walking vehicle with a known hinge system is that the stepping motion bearing abutments are accompanied by oscillations of the frame, due to the changing tipping back the moment of thrust, and the fact that P2">The technical problem of the device is to eliminate tipping back the moment of force produced by the traction force on the trailer clip sample.The task is due to the fact that stepping the vehicle containing the frame, the steering wheel and walking mover with a pair of bearing abutments, provided with lateral supporting wheel and trailer bracket, which is connected to the frame via the d-pad, which is made with the first hinge having an axis located on a straight line and1held perpendicular to the center line lying in the plane of the lines of engagement with the ground bearing abutments mentioned walking thruster in the middle between them, tilted at 45oto the plane of these lines, gearing, and a second hinge having an axis located in the direction of a2and the hole for securing the king pin drawbar hitch and for hinge rotation on the bolt in the plane of lines AND1and2when changing the lateral inclination of the vehicle relative to the trailer unit.The proposed device will reduce to zero the shoulder tipping back the moment of thrust due to the receipt of the imaginary SS="ptx2">The invention is illustrated in the drawing, where Fig. 1-3 depict move the vehicle, and Fig. 1 is a side view, Fig. 2 is a rear view, Fig. 3 is a top view.Move the vehicle has a frame 1, a steering wheel 2, associated with the wheel 3, the side support wheel 4, seat 5, the casing 6 engine hidrotransmisia in the casing 7 of the walking mover.Walking mover with the left and right support abutments 8 and 9, respectively. The frame has a beam that terminates at the rear of the vehicle stationary part of the hinge, the axis 10. The axis 10 is located on a straight "a1"held perpendicular to the center line "b" lying in the plane of the lines of engagement with the ground reference of the toe in the middle between them, and inclined at an angle of 45oto the plane. The line "a1and b intersect at point "O". The movable part of the hinge axis 10 is rigidly connected through the rod 11 with the first part of the hinge with the axis 12 in the direction indicated by line "a2". Hinges form dvukhkontsevoi the cross of the universal joint of the big sizes with the center at point O. the Second part of the hinge axis 12 is towed by a bracket 13 and has a horizontal hole for fastening by the bolt 14 drawbar trailer unit 15.
1and2" when you change the lateral inclination of the vehicle relative to the trailer unit. In other planes compound on the bolt will be hard. The hinge rotation when changing the level of the front wheel will happen in the imaginary hinge, located at the level of the plane of engagement with the ground line, drawn through the point "O". When turning the vehicle left or right hinge rotation will occur vertically 2 passing through the point "O". With the application of the proposed device in walking vehicles overturning moment forces will not be called traction force that will give the trailer the tractor will make the driver more comfortable and safe. There is no need to adjust the hydraulic system in order to reduce the height of the trailer bracket in a dangerous moment. The engagement of the wheels with the ground is more stable.Move the vehicle containing the frame, the steering wheel and walking mover with a pair of bearing abutments, characterized in that it is provided with a lateral support wheel and trailer bracket, which is connected to the frame via the d-pad, which is made with the first hinge having an axis located on a line drawn perpendicular to the center line lying in the plane of the lines of engagement with the ground bearing abutments mentioned walking thruster in the middle between them, tilted at 45oto the plane of these lines, gearing, and a second hinge having a hole for securing the king pin drawbar hitch and axle, designed to pivotally rotate on the bolt when changing the lateral inclination of the vehicle relative to the trailer unit.
SUBSTANCE: coupler contains means for installation on trailer with capability of pivot-hinged turn of at least one left wheel and at least one right wheel, independent means of pivot-hinged turn of trailer and prime mover coupling, means for performing differential turn of wheels and trailer with regard to prime mover in process of turn performed by prime mover. Limiting device is made so as to limit magnitude of wheel turn as compared with wheel turn related to trailer in absence of limiting device. Limiting device contains follower with front end connected with said devices for installation of wheels on trailer and rear end. Follower includes protruding coupling sphere on rear end or near it. Limiting device additionally includes slider guide made so as to couple with prime mover and installed in parallel with or inclined to prime mover and trailer chassis. Coupling sphere is installed with ability to move along slider guide of limiting device in process of prime mover movement.
EFFECT: securing of smooth and safe turning and exclusion of folding effect.
