Abstract
The utility model discloses a hydraulic controlled type differential lock control device. The hydraulic controlled type differential lock control device comprises left and right half shaft sleeves and left and right half shaft bevel gears which are mounted on two sides of a planetary gear carrier, wherein an annular stop shoulder is arranged on the inner wall of the right half shaft sleeve; a differential lock spline shaft is matched and sleeved with the right half shaft sleeve; an annular flange is arranged on the right end of the spline shaft; a separation spring is sleeved with the spline shaft between the annular flange and the annular stop shoulder; a differential lock power cylinder is mounted on the outer side of the right half shaft sleeve; a thrust bearing is mounted at a free end of a piston rod of the cylinder; and a left end face of the thrust spring is contacted with a right end face of the spline shaft. According to the hydraulic controlled type differential lock control device, the power cylinder is used for pushing the spline shaft to be meshed with the bevel gear for working; connection between the spline shaft and the bevel gear is separated through the separation spring; and the hydraulic controlled type differential lock control device is convenient to use.
Description
Technical field
The utility model relates to a kind of hyraulic controlled type differential-lock control for tractor.
Background technique
The differential-lock control being applied at present in tractor mainly contains the differential lock constructional device that differential mechanism built-in hydraulic thrust connects or disconnects, and the differential lock device of friction disk type fluid clutch structure.These differential lock structures are connected closer with differential mechanism mechanical structure, need whole differential mechanism all to open and process and maintaining after breaking down, and have brought certain triviality to maintenance and repair, maintenance work.
Summary of the invention
The purpose of this utility model is to provide a kind of hyraulic controlled type differential-lock control, differential lock splined shaft can be extended outside tractor rear axle housing, when breaking down, differential-speed lock mechanism do not need differential mechanism to open and process, and separately differential-speed lock mechanism is opened, carry out repair process and safeguard processing, thereby improved the simplicity of tractor maintenance and repair maintenance works.
The purpose of this utility model is to realize like this, a kind of hyraulic controlled type differential-lock control, be included in left and right semiaxis axle sleeve and the left and right semi-axle bevel gear that install planetary carrier both sides, one annular shoulder block is being set on right axle shaft axle sleeve inner circle wall, in right axle shaft axle sleeve, coordinate and be set with a differential lock splined shaft, the right-hand end of this splined shaft has an annular flange flange, on the splined shaft between described annular flange flange and described annular shoulder block, be set with release spring, the outside of right axle shaft axle sleeve is installed with a differential lock power cylinder, the piston rod free end of this oil cylinder is installed with a thrust-bearing, the left end face of thrust-bearing contacts with splined shaft its right end face.
When needs differential lock locking work, by hydraulic control system, make the piston rod of oil cylinder drive thrust-bearing to be moved to the left, the elastic force that overcomes release spring pushes differential mechanism inside by splined shaft makes right axle shaft bevel gear, differential lock splined shaft, planetary carrier, left half axle bevel gear realize the function that synchronous combination has completed differential lock connection.
When needs disconnect differential lock, piston rod is moved right, differential lock splined shaft is advanced to the right to make splined shaft pull out differential mechanism inside to make right axle shaft bevel gear, differential lock splined shaft, planetary carrier, left half axle bevel gear realize transmission separation under the effect of release spring, thereby completed the unlocking function to differential lock.
The utility model can extend differential lock splined shaft outside tractor rear axle housing, when breaking down, differential-speed lock mechanism do not need differential mechanism to open and process, and separately differential-speed lock mechanism is opened, carry out repair process and safeguard processing, thereby improved the simplicity of tractor maintenance and repair maintenance works.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is that master of the present utility model looks cross-sectional view.
Embodiment
A kind of hyraulic controlled type differential-lock control, as shown in Figure 1, be included in the left and right semiaxis axle sleeve 9 that install planetary carrier 1 both sides, 4 and left and right semi-axle bevel gear 8, 2, one annular shoulder block is being set on right axle shaft axle sleeve 4 inner circle walls, the interior cooperation of right axle shaft axle sleeve 4 is being set with a differential lock splined shaft 3, the right-hand end of this splined shaft 3 has an annular flange flange, on the splined shaft between described annular flange flange and described annular shoulder block, be set with release spring 5, the outside of right axle shaft axle sleeve 4 is coaxially installed with a differential lock power cylinder 7, the piston rod free end of this oil cylinder 7 is installed with a thrust-bearing 6, the left end face of thrust-bearing 6 contacts with splined shaft 3 its right end face.
