The invention belongs to a pure electric traction vehicle, which comprises a front axle (11) arranged at the left end of a vehicle body component (16). The pure electric traction vehicle is characterized in that an alternating current traction motor (7) is arranged on the vehicle body component (16) arranged on the front axle (11), the alternating current traction motor (7) is connected with a three-gear speed changer (8), the three-gear speed changer (8) is connected with a transmission shaft (9), the transmission shaft (9) is connected with a rear axle (10), front steering wheels (2) are connected with a steering rod (15), the steering rod (15) is hinged to a steering transverse pull rod (14), the steering transverse pull rod (14) is hinged to piston rods arranged at two sides in a hydraulic oil cylinder (12), and the hydraulic oil cylinder (12) is communicated with a hydraulic pump (13) arranged on the vehicle body component (16) through a pipeline. The pure electric traction vehicle has the advantages that the driving force of the alternating current motor is strong, the traction force is strong, the driving range is long, the operation and control are easy, convenient and comfortable, the maneuverability is good, the braking torque is increased, the braking distance is shortened, and the braking safety of the whole vehicle is improved.
Description
Technical field
The invention belongs to tractor truck, particularly a kind of is that what drive take lithium cell as the pure electrically propelled traction vehicle of propulsion source with AC induction motor.
Background technology
At present, in China Logistics industry field, the tractor truck of about 80% is still used as power with fuel oil, but along with the increasing of environmental improvement dynamics and the needs of energy-saving and emission-reduction, electrically propelled traction vehicle has started to replace diesel tractor.More common in existing market is miniature or light-weight tractor, but miniature (or light-duty) tractor truck generally adopts direct drive control technology, and general be propulsion source with lead-acid battery, continual mileage is short, and fault rate is high, and Low Temperature Storage charging and discharging capabilities is poor.This product can not meet the logistics business needs of busy and continuous expansion already.
Summary of the invention
The object of the invention is to overcome above-mentioned technical deficiency, providing a kind of is what drive with AC induction motor, take lithium cell as propulsion source, and tractive force is large, and reliability is high, and continual mileage is longer, have the pure electrically propelled traction vehicle of good dynamics.
The technical scheme that technical solution problem of the present invention adopts is: a kind of pure electrically propelled traction vehicle, and the left end being included in car body member is equipped with propons, at the right-hand member of car body member, back axle is housed; Steering front wheel is equipped with at the two ends of propons, and rear drive sprocket is equipped with at back axle two ends; It is characterized in that the car body member on propons is equipped with AC traction electric motor, AC traction electric motor is connected with three-speed gearbox; Three-speed gearbox is connected with transmission shaft, and transmission shaft is connected with back axle; Steering front wheel is connected with deflecting bar, deflecting bar and tierod hinged, in tierod and hydraulic ram, the piston rod of both sides is hinged; Hydraulic ram pipeline is communicated with the Hydraulic Pump be contained on car body member.Three-speed gearbox presses power performance requriements coupling hand-operated transmission or automatic transmission with hydraulic torque converter.
The invention has the beneficial effects as follows: the strong tractive force of this invention alternating current dynamo propulsive effort is large, and employing lithium cell is propulsion source, makes continual mileage long, has good dynamic property; Especially the all-hydraulic power steering adopted replaces mechanical steering technology, and handle light comfortable, manoevreability is good; Replace dry brake with wet multi-disc brake, extend the life-span of drg, improve lock torque, shorten stopping distance, improve the braking safety of car load.
