摘要： PURPOSE:To improve turning performance of a vehicle eliminated in its so-called earth up phenomenon by providing a lift mechanism which floats a front wheel in the inner side of turning to the upper from a grounded surface when the front wheel is steered in the turning direction exceeding a fixed angle. CONSTITUTION:In the case of a four-wheel drive vehicle of agricultural tractor or the like transmitting power of a prime mover to right and left front wheels F and rear wheels through a differential gear D, a brake mechanism B, applying a brake to either each front wheel F or each rear wheel in a stopped condition, is provided. While swivelably connecting an upper surface protrusion of the front wheel differential gear D (FD) to the central bottom part of a front axle device 4 through a supporting shaft 41, a cylinder 44, constituting a lift mechanism 10, is arranged in both side parts of a car body 40. And when one of the right and left front wheel brake mechanisms B (FB) is actuated, further when the front wheel is steered exceeding a fixed angle in the turning direction, the lift mechanism 10 is driven and controlled so as to lift the front wheel F in the inner side of turning.

摘要： PURPOSE:To make is comfortable to ride in, by subjecting an action line of tilling reaction force to pass through a virtual hitch point and lowering the gravity center of a main machine of tractor to lessen pitching moment. CONSTITUTION:An action line of a tilling reaction force pi is made to pass through a virtual hitch point A at which extended lines of a low line 14 and a top link 15 are crossed, tail wheel reaction force R6 is made approximately constant and the size of tilling resultant force P is also made approximately constant. The action one of the tiling resultant force P is made to pass through the gravity center CG of a main machine 1 of tractor, pitching moment is lessened, pitching vibration is suppressed and the size of vibration is made constant.

摘要： PURPOSE:To improve the turning performance on the ground by setting the outside among a plurality of clutch brake mechanisms into the cut-off stop state and setting the inside to transmission state, when the steering angle for the front wheel is steered over a certain value to the brake-applied rear wheel side. CONSTITUTION:When the right and left front wheels Fl are steered, for example leftward, a switch control mechanism 4l for the left front wheels Fl and a clutch brake mechanism 10l are kept in the ordinary state. While, a receiving lever 51r of the right side switch control mechanism 4r is attached onto the pushing lever 37r of a front knuckle 30r, and the turn of the pushing lever 37r is transmitted to a shifter lever 42r through a control ring 48r, fan-shaped projection 50r, fan-shaped notch, and shifter shaft 41r. Therefore, the clutch brake mechanism 10r on the right side is switch to the cut-off stop state. While, a front axle 13l on the left side is revolved at an increased speed by the action of a front wheel differential gear device FD.

摘要： PURPOSE:To improve the turning performance for the ground by putting a clutch brake mechanism on the outside in turning into cut-off stop state and putting a clutch brake mechanism on the inside in turning to a transmission state, when the steering angle of a front wheel exceeds a certain value. CONSTITUTION:When a front wheel shaft 25 is steered to the max. angle, for example, leftward through an intermediate shaft 22, a pushing piece 190 of a right side front wheel is turned in the counterclockwise direction, and a receiving piece 170 engaged with the pushing piece 190 is turned in the clockwise direction, and a shift block 70 on a right side front wheel side is shifted close to the center CL of a vehicle. Transition from the ordinary state where the dog 60 of a bevel gear 50 and a driving dog 90 are engaged to a brake state where the engaging dog 61 and a fixed dog 120 are engaged is performed. Since the pushing piece 191 of a left front wheel side F1 is not engaged with the receiving piece 171, the ordinary state where the dog 61 and the driving dog 91 are engaged is maintained. Therefore, the leftward turning performance for the ground can be improved.

摘要： PURPOSE:To reduce reduction of resistance and decrease a turn radius during turn, by a method wherein a front wheel on the inside in a turn direction is lifted up from a road surface during earth turn. CONSTITUTION:A hydraulic type reciprocating cylinder 20 is located between an axle tube 12 and a car body 13. In the reciprocating cylinder 20, a cylinder body 21 is secured to a car body frame 13, and a projection 12a formed in an axle tube 12 is inserted in an oblong hole 22a of a rod 22. The reciprocating cylinder 20 is coupled to a 3-position electromagnetic switching valve 23, and is actuated by means of pressure oil fed from the electromagnetic switching valve 23. In the reciprocating cylinder 20, by clockwise slewing of an axle tube 12 through the contraction action thereof, a right front wheel 15R is moved upward from the car body frame 13 to lift it up from a ground surface G, and by the slewing of the axle tube 12 through the expansion action thereof, a front wheel on the left side is moved upward from the car body frame 13 to lift it up from the ground surface G.
