Mechanical drive mode low cost of manufacture, maintenance difficulty is little, operation is convenient, is widely used in the railcar below power 270kW. But it is many that the shortcoming of this kind of drive is parts, from great, fault is many, and maintenance load is large.
Fluid power-machine driving railcar is taking diesel engine as power, be connected with hydraulic transmission box or fluid torque-converter power shaft by crankshaft of diesel engine, power is delivered to hydraulic transmission box or Output Shaft of Hydraulic Torque Converter, then by universal drive shaft, power is passed to axle gear box, axletree and wheel. The advantages such as fluid power-mechanical transmission-type railcar has infinitely variable speeds, it is simple to handle, Acceleration of starting is steady, hauling ability is good, functional reliability is good, long service life. Shortcoming be hydraulic transmission box or fluid torque-converter manufacturing technology content is high, cost is high, maintenance require high, mechanical efficiency is low; Bogie part is mechanical drive mode, and deadweight, volume is large.
Electrically-driven tram car is generated electricity by Diesel Driven pulling electric generator, and the alternating current that pulling electric generator is sent is after silicon rectifier device rectifying and pressure-regulating, for the direct axle shaft of traction motor and vehicle wheel rotation; The direct current that pulling electric generator is sent is after pressure regulation, for traction motor axle shaft and vehicle wheel rotation. Electrically-driven tram car adopts AC-to-DC electric transmission, have that power is large, driving power is strong, advanced technology, overhaul life are long, easy to maintenance, utilization low cost and other advantages, at present, the electrically-driven tram car of existing multiple power puts into effect, but also has the shortcoming such as car load complex structure, manufacturing cost height.
Summary of the invention
For solving above technical deficiency, the invention provides a kind of fluid motor-driven power truck, right by gear-box variable speed drives wheel with hydraulic motor, utilize hydraulic motor volume little, from heavy and light, the output advantages such as torque is large, greatly simplify bogie structure, reduce and conduct oneself with dignity and save installing space.
The present invention is achieved by the following measures:
A kind of fluid motor-driven power truck of the present invention, comprise frame assemblies, in described frame assemblies, be provided with wheel to assembly, axle box assembly, primary spring, secondary suspension system, brake apparatus and drive unit, described drive unit comprises hydraulic motor, described hydraulic motor is connected with mount pad, described mount pad is fixed in frame assemblies, the output shaft of hydraulic motor is driven and is connected with gear-box by flexible coupling, described gear-box is connected to the axletree of assembly with wheel, gear-box is connected with hanger rod component, described hanger rod component hangs and is connected in frame assemblies.
