Abstract
Disclosed is a high ground clearance self-propelled type base plate with adjustable gap from the ground. The high ground clearance self-propelled type base plate with adjustable gap from the ground comprises a driving room, a lifted ladder, a car frame, a front axle and a rear axle, a ground clearance adjusting system and a power system. The ground clearance adjusting system comprises a controller, a servo valve and a ground clearance adjusting hydraulic cylinder. The power system further comprises a motor, a clutch, a pump station, a hydraulic pressure motor, a proportion valve, a front wheel and a back wheel. The servo valve is controlled by the controller, and thus the synchronous lifting of four ground clearance adjusting hydraulic cylinders is adjusted. The gap between the base plate and the ground is changed stably. The motor is connected with the pump station through the clutch. The hydraulic motor is driven by the pump station, thus the front wheel and the back wheel are driven to revolve. The opening of the proportion valve is controlled by a hydraulic pressure steering gear, thus the discharging capacity of the hydraulic pressure motor is adjusted. The revolving speed of the four wheels is adjusted. The differential steering of the four wheels is achieved. The passing ability of the base plate is guaranteed. The high ground clearance self-propelled type base plate can be suitable for the operation of different ground clearance requirements. A complex machinery transmission mechanism designed for guaranteeing the gap from the ground is avoided at the same time. The self weight of the base plate is effectively reduced.

Propons comprises: left and right swing arm, propons vertical axes, contiguous block in the middle of propons, the left and right anticollison block of propons, front axle damper spring.Left and right swing arm is by contiguous block in the middle of the propons that is articulated and connected, and the front axle damper spring housing connects respectively in left and right swing arm by welding on the left and right anticollison block of propons on the left and right anticollison block of propons.Propons is articulated on described vehicle frame by contiguous block in the middle of propons.Described left and right swing arm can be rotated around middle contiguous block, and the right wheel of propons left wheel, propons that propons connects is beated separately, thereby reduces the vibrations of vehicle body.
Back axle comprises: rear vehicle bridge tween drive shaft, back axle vertical axes, back axle contiguous block, back axle vibration damping spring plate.Back axle contiguous block welding tween drive shaft.Back axle is articulated on vehicle frame by the back axle contiguous block.The damper spring steel plate is bolted on back axle contiguous block and vehicle frame.
The liftable ladder is articulated on vehicle frame, and lifting hydraulic cylinder is by hinged described liftable ladder and the propons of connecting respectively.
Ground gap control system is by controller, servovalve, and four ground gap regulator solution cylinder pressures form.Four ground gap regulator solution cylinder pressure one ends connect respectively front axle vertical axes, back axle vertical axes by screw thread bush.The other end is weldingly connected with the tween drive shaft of left swing arm, right swing arm and the back axle of propons respectively; When the chassis need to change during ground gap operation, can control servovalve by controller and regulate the synchronization lifting of four ground gap regulator solution cylinder pressures and change the chassis ground Clearance.
The present invention has following technology beneficial effect:
The present invention can control servovalve by controller and regulate four ground gap regulator solution cylinder pressure synchronization liftings and change reposefully the chassis ground Clearance, guarantees the crossing ability on chassis, thereby can be suitable for the farm work requirement of multiple ground Clearance.
The present invention regulates hydraulic steering gear and control ratio valve opening by steering wheel rotation, thereby regulator solution pressure motor discharge capacity changes the rotating speed of four wheels, realizes that four-wheel differentia turns to, and effectively reduces turn radius, turns to more steady.
The present invention improves the ground Clearance by forward and backward bridge, adopts the four-wheel hydraulic-driven, has avoided the mechanical transmission mechanism of the complexity that designs in order to guarantee the ground Clearance, effectively reduces the chassis deadweight.
Propons can make left and right wheel beat separately by horizontal swinging arm, and the damper spring steel plate of the damper spring of propons and back axle can reduce vibration and impact that vehicle body causes because of the ground excitation, riding stability and the driver comfort on chassis thereby improvement is walked.
