Abstract
The utility model discloses a tractor axle regulating mechanism, which mainly consists of hydraulic cylinders (10), universal couplings (7), support arms (11). The two universal couplings are arranged between power output ends (9) and the semi-axles (1) of wheels on the left side and the right side of a transmission case. The two hydraulic cylinders are arranged on the left side and the right side of the transmission case symmetrically. Support arms (11) are arranged on the left side and the right side of the transmission case symmetrically. The regulating mechanism further comprises a hydraulic pump driving a hydraulic pump to work and a manual multiway control valve. The hydraulic pump is connected with the output of a diesel engine. The regulating mechanism is designed reasonably; the wheels and a vehicle body are joined flexibly through the universal coupling. The support arms limit the oscillation of the wheels back and forth along the vehicle body to ensure that the wheels can only move up and down relative to the vehicle body. By adopting the oil cylinders, the wheels can move up and down freely relative to the transmission case and the vehicle body, thus preventing the barycenter of the vehicle body from deviating and further preventing roll-over accidents.
Description
Affiliated field
The utility model relates to farm tractor, mainly proposes a kind of trac. wheel shaft regulating mechanism.
Background technology
Trac. wheel shaft regulating mechanism is applied to the farmland tractor-ploughing operation of mountain area, high-land.China is a large agricultural country, and along with agro based economic development, trac. and facility have had bigger recoverable amount in the man of peasant household.Quite a few is in mountain area, high-land China rural area, and trac. is when the operation of hillside fields, if single wheel is in high point, opposite side is in low spot, then is easy to cause roll-over accident, and the application of trac. and corresponding agricultural machinery and implement is subjected to certain limitation.
Summary of the invention
The purpose of this utility model promptly is to propose a kind of trac. wheel shaft regulating mechanism, to solve the problem that trac. and corresponding agricultural machinery and implement exist in the hillside fields operation.
The technical scheme that the utility model is finished its invention task proposition is: regulating mechanism mainly is made of hydraulic actuating cylinder, universal coupling and hold-down arm, wherein, two universal couplings are separately positioned between the semiaxis of the clutch end of the change speed gear box left and right sides and wheel, hydraulic actuating cylinder is two covers and is symmetricly set on the change speed gear box left and right sides, its cylinder body one end connects with body, and the piston rod of the other end is connected with bearing seat on the wheel semiaxis; Hold-down arm is positioned at the change speed gear box left and right sides and is symmetrical arranged, and an end of hold-down arm is connected with body, and the other end is connected on the bearing seat on the wheel semiaxis; Regulating mechanism also is provided with in order to drive the Hydraulic Pump and the manual multidirectional control cock of hydraulic cylinder works, and Hydraulic Pump and diesel engine output link.
The cylinder body and the body of hydraulic actuating cylinder are hinged, and the other end piston rod and the bearing seat on the wheel semiaxis of hydraulic actuating cylinder are hinged.
The every side of change speed gear box is symmetrical arranged before and after having two hold-down arms and two hold-down arms, and an end and the body sphere of hold-down arm are hinged, and the bearing seat sphere on its other end and the wheel semiaxis is hinged.
Universal coupling described in the utility model, its pattern are Cardon universal joint or ball cage type.
The trac. wheel shaft regulating mechanism that the utility model proposes is reasonable in design, and the universal coupling of its setting makes and constitutes flexible the connection between wheel and the change speed gear box; The hold-down arm of its setting makes wheel be restricted along the swing of change speed gear box fore-and-aft direction, and above-below direction can move freely; The oil cylinder of its setting can make wheel move freely with respect to the above-below direction of change speed gear box and car body, when trac. carries out operation in the hillside fields, by manually actuated control valve the hydraulic actuating cylinder that is in high point one side is shortened, make the hydraulic actuating cylinder elongation that is in low spot one side simultaneously, guarantee that body gravity is not offset and avoids the generation of roll-over accident.
