Abstract
The utility model relates to a novel transfer case of an agricultural vehicle. The novel transfer case of the agricultural vehicle is simple in structure, low in manufacturing cost and high in practicality. The novel transfer case of the agricultural vehicle comprises a case body, an output shaft and a speed-changing shaft, wherein the output shaft and the speed-changing shaft are arranged on the case body in a rotary mode. A first sliding gear sleeve is arranged on the output shaft through a spline in a left-and-right sliding mode and a second sliding gear sleeve is arranged on the speed-changing shaft through a spline in a left-and-right sliding mode. A shifting fork capable of controlling the first sliding gear sleeve and the second sliding gear sleeve to slide left and right to change the rate is arranged on the case body. A change gear is arranged at the right side of the first sliding gear sleeve and on the output shaft through a woodruff key. A small gear is arranged on the speed-changing shaft through a woodruff key.
Description
Technical field
The utility model relates to a kind of Novel agricultural vehicle transfer case.
Background technique
At present, so-called transfer case, carry out assigned unit by the power of motor exactly, can output power to rear axle, or output to front/rear axle simultaneously.Existing a kind of transfer case of agricultural vehicle, comprise casing and be located at rotationally the input shaft on casing, output shaft, variable-speed shaft, described input shaft and output shaft coaxially arrange, can be provided with the first sliding gear collar by spline slippingly in left and right on described output shaft, be provided with speed change gear by spline, the engagement drive output shaft of the left slippage of described input shaft by sliding gear collar and input shaft synchronize rotation, be provided with gearwheel by needle bearing on described variable-speed shaft, be provided with small gear by spline, can be provided with slippingly the second sliding gear collar in left and right by spline, described large, small gear can be realized by the left slippage of the second sliding gear collar engagement synchronous the rotation, described gearwheel and input shaft engagement driving, speed change gear engagement driving on described small gear and output shaft, also be provided with shift fork on described casing and carry out the left and right slippage to realize the change of speed to control the first sliding gear collar and the second sliding gear collar, described shift fork is installed with speed change lever by round pin.Due to speed change gear, small gear, it is not slided on output shaft and variable-speed shaft, existing transfer case is for easy to assembly, usually be all to utilize spline to realize the clamping between it, but this method of utilizing the spline assembling, and it adds the higher control that is unfavorable for cost of cost in man-hour.
Summary of the invention
Therefore, for above-mentioned problem, the utility model proposes a kind of simple in structure, Novel agricultural vehicle transfer case that cost is lower, practical.
For achieving the above object, the utility model has adopted following technological scheme: a kind of Novel agricultural vehicle transfer case, comprise casing and be located at rotationally the output shaft on casing, variable-speed shaft, can be provided with slippingly the first sliding gear collar in left and right by spline on described output shaft, can be provided with slippingly the second sliding gear collar in left and right by spline on described variable-speed shaft, described casing is provided with to be controlled the first sliding gear collar and the second sliding gear collar and carries out the shift fork of left and right slippage with the change that realizes speed, the right side that is positioned at the first sliding gear collar on described output shaft is provided with speed change gear by woodruff key, be provided with small gear by woodruff key on described variable-speed shaft.
Further, offer a flat nick on the side of described shift fork, the position that is positioned at flat nick on described shift fork is provided with speed change lever, described speed change lever is provided with the taper pin that runs through two ends, speed change lever left and right and coordinate with flat nick, the end riveted that described taper pin passes speed change lever drops out to prevent taper pin, and described speed change lever was fixedly arranged on shift fork by taper pin and coordinating of flat nick.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: compare this Novel agricultural vehicle transfer case with existing transfer case of agricultural vehicle and be connected by speed change gear and small gear are changed into to woodruff key with the spline joint of output shaft and variable-speed shaft, realize the reduction of processing cost, and make the stressed increasing of output shaft and variable-speed shaft, more practical, longer service life; Further, fixedly changing into taper pin by the round pin by speed change lever and shift fork fixes, by coordinating of flat nick and taper pin, make fixing closelyr, and after wearing and tearing, taper pin still can slip into locking, uses more convenient, fastening better effects if, and making after the use wearing and tearing, not there will be becoming flexible between speed change lever and shift fork, round pin is because of unfavorable conditions such as vibration come off.
The accompanying drawing explanation
Fig. 1 is the structural representation of this Novel agricultural vehicle transfer case inside.
Fig. 2 is the fixing structural representation of round pin between original speed change lever and shift fork.
Fig. 3 is the fixing structural representation of taper pin between the utility model speed change lever and shift fork.
