Abstract
The invention relates to a hydraulic power towing tractor which is composed of a cab, a driven axle, a frame, a driving axle, a towing device, an engine compartment, a jacking device and a hydraulic control system. The driven axle and the driving axle are arranged at the bottom of the frame. The driven axle is located at the front of the frame. The driving axle is located at the rear of the frame. The engine compartment is arranged behind the frame. The jacking device is located in the middle of the frame. The towing device is located at the rear of the frame. A pin shaft hole is formed in the connecting end of the towing device. The cab is fixedly arranged at the front of the frame and comprises a cab front part and a cab rear part. The hydraulic control system is arranged on the cab rear part. The hydraulic power towing tractor has the advantages of being compact in whole structure, short in length, narrow in width, and easy, convenient and quick to operate. The hydraulic power towing tractor can tow a semi-trailer or a full trailer, is suitable for transferring an empty trailer back and forth in a factory area or in a short distance, or transporting light-loading goods in the short distance, is suitable for places which are limited in space, short in distance and frequent in transferring, and is stable and reliable in working, and high in efficiency.
Description
Technical field
The invention belongs to the trackless terrestrial vehicle field, relate to a kind of hydraulic power tractor truck.
Background technology
At present, superimposed trailer or independent trailer all do not have the engine installation that carries, and need the traction of wheel tractor to travel.Finishing on-site or short range under the driving of wheel tractor comes and goes when shifting unloaded trailer or short range transportation underloading goods, because wheel tractor volume restrictions, turn radius is big, higher to site requirements, very flexible, inefficiency sometimes even the job requirements of can not realizing ideal, and needs the professional driver.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of compact overall structure is provided, length is short, width is narrow, simple and efficient to handle, be adapted at small space or short range transit vehicle, the hydraulic power tractor truck that working stability is reliable, efficient is high.
The object of the present invention is achieved like this:
A kind of hydraulic power tractor truck, it is by operator's compartment, driven bridge, vehicle frame, drive axle, draw gear, piggyback pod, jacking apparatus, hydraulic control system is formed, described driven bridge and drive axle are arranged at bottom of frame, described driven bridge location is in the vehicle frame front portion, described drive axle is positioned at the vehicle frame rear portion, described piggyback pod is arranged at the vehicle frame rear, described jacking apparatus is by the towing pin base, jacking fixed mechanism and plunger case are formed, the jacking fixed mechanism is fixed on the vehicle frame middle part, the plunger case cylinder barrel is connected with the jacking fixed mechanism, and plunger case cylinder bar is vertical with vehicle frame, and plunger case cylinder masthead end and towing pin base are hinged; Described draw gear is positioned at the vehicle frame rear portion, is provided with pin shaft hole at the coupling end of draw gear; Described operator's compartment is fixedly set in the vehicle frame front portion, and described operator's compartment comprises operator's compartment front portion and rear cabin, is provided with hydraulic control system in rear cabin.
Described hydraulic control system comprise tractor truck driving, turn to, the drive system of brake system and plunger case;
Described jacking apparatus is connected with the towing pin of superimposed trailer by the towing pin base;
Described draw gear is connected with the draw bar of independent trailer by bearing pin.
Compared with prior art, the present invention has following beneficial effect:
Hydraulic power tractor truck of the present invention can draw superimposed trailer or independent trailer, suits to come and go the unloaded trailer of transfer or short range transportation underloading goods at on-site or short range, and suitable space is limited, distance is short and transport occasion frequently; Towing pin base in the jacking apparatus is connected with the superimposed trailer towing pin, can make things convenient for the height that is connected of adjusting and superimposed trailer or gooseneck type trailer by the control oil cylinder, towing pin can freely rotate around base, and vehicle can be turned in the narrow space realization, turn to more flexibly, draw convenient; Draw gear is connected with the independent trailer draw bar by bearing pin, realizes the driving of independent trailer; This tractor truck adopts hydraulic efficiency pressure system to drive, and power output is big, handling good.
