Description
Technical field
The present invention relates to a kind of tractor more particularly to a kind of articulated steering steering wheel tractors.
Background technology
Currently, improved articulated steering steering wheel tractor transports on the basis of rural area is commonly used in hand tractor.
Existing articulated steering steering wheel tractor improved on the basis of hand tractor lacks though can overcome existing for hand tractor
Point, but still have the disadvantage that：Existing articulated steering steering wheel tractor is located at because of steering wheel in the Rear frame of driver's cabin front,
Front frame Drag link pulls point to be located on the corresponding lateral position of articulated steering stub of the rear portions Qian Qiao, with pulling open driver's cabin and preceding bridge
Distance to obtain required vertical pulling pole length, cause driver's cabin to tie up loading space position, loading space is too short；Existing articulated steering side
To disk tractor Front Leaf Spring length because being limited by the steering wheel Drag link for being located at frame downward, preceding bridge steel plate is too short almost
Nonelastic, rear haulage seat is still the last century forward and backward bridge of the seventies hand tractor need to use rear haulage seat without leaf spring suspension
The structure for making forward and backward tire land can be rotated in Rear frame tube socket, as Patent No. CN201520051258.4 one kind can before
The tractor rear haulage seat of four-wheel drive is still the structure that can be rotated in Rear frame pipe sleeve afterwards, and the traction seat is complicated, makes
Valence is high, and causes that vehicle damping ability is low, traveling is unstable；Existing articulated steering steering wheel tractor is because connecting forward and backward vehicle frame
Pivot stud end back rake angle is set, cause direction of traffic to be unable to self-aligning, direction to control is difficult；Existing articulated steering direction
Because headlight is located on driver's cabin, Ackermann steer angle is arranged on the parts shelves such as engine of driver's cabin front and lives lamp disk tractor
Light influences driving at night safety；Existing articulated steering steering wheel tractor laterally pulls engine throttle control to turn because of throttle line
There is length variation with turn inside diameter in speed, throttle line, cause engine speed to increase and reduce automatically and even stop working, influence to drive a vehicle
Safety.Existing articulated steering steering wheel tractor is in addition to there are above-mentioned major defect, and there is also other shortcomings.
Goal of the invention
Long, steering that it is an object of the present invention to provide a kind of loading compartments is easily, smooth ride, easy to use, cross-country power is strong
A kind of tractor.
For existing articulated steering steering wheel tractor there are the shortcomings that, the scheme that the present invention solves its technical problem is：
For the cushioning ability and cross-country power for obtaining maximum loading space length, improving vehicle, move forward driver's cabin, moves steering wheel afterwards, turns
To being setting transmission case, steering wheel drive link is become horizontal conveyor from hypsokinesis transmission with the transmission case, is driven by transfer case
Bar control direction machine；The steering wheel output shaft being fixed in Rear frame is vertically arranged, and the swing arm being fixed on the output shaft is horizontal
It swings, pulls front frame to turn to by Drag link and the preceding ball cup being fixed in front frame.
Another program is：Transmission case is arranged in steering system, and steering wheel drive link is become water from hypsokinesis transmission with the transmission case
It flates pass dynamic, passes through transfer case drive link control direction machine；The steering wheel output shaft being fixed in Rear frame is laterally arranged, and is fixed on
Swing arm vertical oscillation on the output shaft pulls front frame to turn to by Drag link and the preceding ball cup being fixed in front frame.
To keep traction seat simple and reliable for structure, rear haulage seat is fixed in Rear frame.
To make direction of traffic self-aligning, turning to light, pivot stud setting back rake angle.
To make light preferably impinge upon road surface, mask is set in the front of front frame, headlight is set on the mask.
Throttle is caused to increase and reduce even flame-out, use automatically to avoid Ackermann steer angle throttle line from length variation occur
The upper and lower mode for pulling throttle pivoted arm controls engine speed.The throttle line is turned from upper position of engine by connecting throttle
Arm pulls up throttle pivoted arm control engine speed；The throttle line from engine lower part by connect throttle pivoted arm, to
Lower pulling throttle pivoted arm controls engine speed.
To keep braking system service brake simple and reliable for structure, brake pedal and master cylinder are connected with bracing wire, is drawn with bracing wire
Dynamic master cylinder is braked；To make braking system parking braking manipulation freely, the instrument on the right side of steering wheel is arranged in parking hand control valve
On table platform.
To increase the secondary seating width sat, Rear Derailleur gear lever avoids counter-base to driver's curving；To become after making
Gear lever fulcrum bulb is made and swings needed for gear selecting to light fork shift is remained to after driver's curving by fast device gear lever
Oblong aperture, the ball stud for being fixed on ball cup crosses in the oblong aperture, and balanced support gear lever swings gear selecting, front and back pendulum
Dynamic fork shift.
The great advantage of the present invention is that loading compartment is long, steering is light, smooth ride, easy to use, cross-country power is strong.
