Summary of the invention
The utility model is in order to solve existing heavy rail motor car bogie structure complexity, and reliability hangs down the problem that can not satisfy the requirement of rail vehicle high-speed cruising, and a kind of bogie truck of heavy rail motor car is provided.
The utility model is concrete to adopt following technical scheme to realize: the bogie truck of heavy rail motor car, comprise the box framework, hang the axle box be fixed on the framework, be supported in two wheels on the axle box being fixed on two motors on the truck frame with suspension, two motors are center-point with the bogie pivot center, the built-in suspension that is centrosymmetric is installed, and the framework down either side is respectively arranged with connecting lever assembling pin bonded assembly draw bar on an end and the framework.
This device truck frame adopts the box type construction of steel plate welding, and axle box is the no drawing strickle guide axle box of pull bar location, and single stage suspension adopts the circle spring version in parallel with oil-pressure damper; The quadruplet foundation brake rigging is housed on every bogie truck; The traction motor suspension mode adopts the rolling axle suspension bearing, and the built-in suspension that is centrosymmetric is installed, and this structure makes bogie structure compacter, and gravity centre distribution is more even.
The upper surface of every truck frame is equipped with two groups of rubber metal pad side bearings, and car body is supported on four groups of rubber metal pad side bearings of trailing or leading bogie, with the carrying vertical load.Bogie truck links to each other with car body with low level draw bar mechanism, and in order to longitudinal loadings such as transmitting tractive power, braking forces, the axle that effectively reduces rail vehicle heavily shifts, and improves utilization of adhesion, plays the effect of low level traction.Between bogie truck and car body, be provided with elasticity side retaining, make it, can make bogie truck within the specific limits, make gyroscopic movement around car body with an invisible center with draw bar mechanism.
Compared with prior art, the bogie truck of the heavy rail motor car that provides of the utility model has the following advantages:
1, the traction motor built-in suspension that is centrosymmetric is installed, and gravity centre distribution is even, makes rail vehicle have good dynamic performance, to adapt to the needs of high-speed cruising;
2, adopt one group of low level draw bar mechanism, make the heavy transfer amount minimum of axle of rail vehicle, and improved utilization of adhesion, to satisfy the requirement that improves the rail vehicle tractive force;
3, this device has good accessibility, guaranteeing to reduce maintenance load under the utilization reliable premise, to adapt to the operation environment of railway department better, especially adapts to the use of the heavy rail motor car of high-speed cruising.
