The invention discloses a front steering device capable of changing wheel span and ground clearance. The front steering device capable of changing the wheel span and the ground clearance comprises a steering shaft, a left wheel steering device, a right steering device, a left and right steering linkage device, a ground clearance adjusting device and a wheel span adjusting device, wherein the left and right steering linkage device comprises a steering transverse pull rod device arranged between the left wheel steering device and the right steering device; a left transmission device is arranged between the steering transverse pull rod device and the left wheel steering device; a right transmission device is arranged between the steering transverse pull rod device and the right steering device; the ground clearance adjusting device comprises a ground clearance left adjustment device and a ground clearance right adjustment device which are arranged on the left wheel steering device and the right steering device respectively; and the wheel span adjusting device is arranged on the steering transverse pull rod device. The ground clearance adjusting device can adjust the ground clearance conveniently, so that the requirement of crop height on vehicle trafficability is met; and the wheel span adjusting device can adjust the wheel span conveniently, so that different ridge widths are adapted. The front steering device capable of changing the wheel span and the ground clearance has the advantages of reasonable structure, reliable function and convenience of adjustment.
Description
technical field [0001] The invention relates to a vehicle steering device, in particular to a vehicle steering device capable of changing wheelbase and ground clearance. Background technique [0002] In agricultural production, due to the different ridge widths of farmland in different regions, when using agricultural vehicles for cross-regional operations, it is often necessary to adjust the wheelbase of agricultural vehicles; in addition, the height of crops in different periods is also different and needs to be adjusted The ground clearance of agricultural vehicles can meet the requirements of the height of crops for vehicle passability. However, after the existing variable wheelbase and variable ground clearance agricultural vehicles have variable wheelbase and variable ground clearance, the front steering system of the tractor has poor ability to adapt to the variable wheelbase and variable ground clearance. Poor performance, resulting in difficult control, easy to cau...
