Abstract
A gearbox for driving a trailer of a hand tractor comprises a machine body which is internally provided with an input shaft and an output shaft; a driving gear is arranged on the input shaft, and a driven gear is arranged on the output shaft; the machine body is also internally provided with an intermediate transmission shaft on which a transmission gear meshed with the driven gear and the driving gear respectively is arranged; the gearbox is characterized in that a clutch device for controlling the driving gear is arranged on a cover of the machine body; the clutch device is provided with a pull handle which is installed on the cover of the machine body through a rotation shaft; the machine body is internally provided with a sliding shaft on which a shifting fork for stirring the driving gear to move is arranged; a deflector rod for controlling the shifting fork to move is further arranged on the pull handle; the deflector rod on the pull handle is utilized for stirring the shifting fork to move on the sliding shaft; the shifting fork drives the driving gear to move on the input shaft so as to realize separation and combination of the driving gear and the transmission gear; and gearbox has the advantages of improving the using safety, being firm and durable, having low fault ratio, and being not limited by operating environment.
Description
Technical field
The utility model belongs to a kind of speed change gear, and particularly a kind of hand tractor drives the trailer gearbox.
Background technique
Hand tractor is a kind of farm machinery commonly used, is mainly used in farming operation and hauling operation.When carrying out hauling operation; Hand tractor will hang up the transportation trailer; Existing transportation trailer itself does not have power plant, and full armrest holds up tractor to drag, in the ramp or road conditions when relatively poor; Regular meeting tractor occurs and changes problems such as not performing, skid, adhesion is not enough, braking force is not enough, influences traffic safety.In order to address the above problem; People improve the rear axle of transportation trailer, the installing drive device, and on the transportation trailer, install transfer case and speed reducer additional; And then couple together with the motor of chain with speed reducer and hand tractor; Power with the hand tractor directly drives the transportation trailer, and 4 wheel driven before and after the hand tractor is become by original independent forerunner's traction when the hauling operation is in the utilization ratio that keeps the hand tractor; Improve and improve the adhesion property of hand tractor transportation unit, improve conveying efficiency and Safety performance.But one of chain transmission is dangerous, and easy clothing or other article with the driver are winched in the running process, cause the personal safety accident.Another is the restriction that receives operating environment easily, under relatively poor or muddy environmental conditions, during operation, causes chain to block easily or the chain fracture, in case and accident just appears in chain fracture easily.In addition, chain is exposed also to get rusty easily outside, and working life is short, changes frequent.
Summary of the invention
The technical problem that the utility model will solve is; Overcome short problem of poor stability that existing hand tractor exists with chain drive transportation trailer, fracture easily, working life, provide a kind of safe and reliable, robust hand tractor to drive the trailer gearbox.
The utility model has a body, and input shaft and output shaft are housed in body, and driving gear is housed on input shaft; Driven gear is housed on output shaft, intermediate propeller shaft also is housed in body, the driving gear that is meshed with driven gear and driving gear respectively is housed on intermediate propeller shaft; Its special way is, the engaging and disengaging gear of control driving gear is housed on the cover of body, and described engaging and disengaging gear has a handle; Handle is installed in through rotatingshaft on the cover of body, and a sliding axle is housed in body, on sliding axle, is equipped with one and stirs the shift fork that driving gear moves; The driving lever that on handle, also has a control shift fork motion; Utilize driving lever on the handle to stir shift fork and on sliding axle, move, drive driving gear through shift fork and on input shaft, move, realize the clutch of driving gear and driving gear.
Positioning device also is installed on handle, and described positioning device is made up of screw, spring and steel ball, and cover is provided with the semicircular recess that matches with steel ball, all can locate in engagement and separated state to guarantee driving gear and driving gear.
The advantage of the utility model is:
1, adopt gearbox to replace chain, improved the Security of using, and sturdy and durable, be not easy to break down, do not receive the restriction of operating environment yet.
2, engaging and disengaging gear is set on gearbox, has realized the powershift between hand tractor and the transportation trailer, the convenient use, and easy and simple to handle.
Description of drawings
Fig. 1 is the structural representation of the utility model;
