The objective of the invention is to be achieved through the following technical solutions: a kind of bogie truck of single-motor drive double-shaft, comprise framework, brake block, brake disc, shock absorber, wheel is taken turns to axle drive motor, coupler, gear case, parts such as secondary spring.It is characterized in that: bogie truck adopts single-motor drive double-shaft way, by a motor simultaneously to two axle driven in synchronism of bogie truck.Be provided with drive motor at the bogie truck middle part, the drive motor both sides are furnished with two gears case, the axle two ends of drive motor are connected by the gear of two gears case respectively axle with two wheels, and drive motor is installed on the truck transom, motor shaft with take turns parallel to axle.Motor shaft and gear case driving gear shaft link.The gear cluster that is used for speed change is housed in the gear case.Gear cluster comprises driving gear, intermediate gear and big gear wheel.Big gear wheel tightens together to axle by interference fit and wheel, and wheel tightens together by interference fit and wheel again to axle.After the drive motor energising, motor shaft drives the driving gear rotation, and driving gear drives the big gear wheel rotation by intermediate gear simultaneously, relies on big gear wheel and wheel to the interference fit of axle and the wheel interference fit to axle and wheel, make wheel revolutions, at this moment locomotive or vehicle begin walking.Brake disc is installed on the wheel by bolt, and glancing impact forces brake block to compress brake disc by high pressure air, relies on the friction force between brake block and the brake disc, wheel revolutions speed is reduced or stops the rotation, and reaches the braking purpose.In order to satisfy because drive motor places on the framework, when locomotive or vehicle operating, framework and wheel between exist each to displacement (mainly being vertical deviation), cause drive motor and wheel between also produce the requirement of displacement, respectively increased a coupler at the two ends of motor, coupler not only can be safe and reliable the moment of torsion of transmission motor, and can adapt to motor and wheel between displacement.In order to reduce to cause influence to car body from the vibration on the bogie truck, secondary spring and four shock absorbers have been installed on framework, the other end of shock absorber is connected to car body.
The invention has the advantages that: bogie truck adopts single-motor drive double-shaft, and motor places on the crossbeam of framework, two-wheeled greatly reduces the distance of axle conventional diaxon and three axle truck, make the angle of attack between wheel and the track reduce during by bend, alleviated the abrasion relation between wheel and the rail greatly, not only alleviated the destructive effect of rolling stock, and prolonged the service life of wheel and rail, and the critical speed that makes rolling stock pass through bend improves circuit.
Simultaneously, interknit (coupling) by a shared drive motor between two axle drive shafts, any one is taken turns and all takes turns axle relevantly with another to the driving of axle and braking, has realized that two wheels link to axle.The variation of rail level adhesion coefficient if any one is taken turns axle, axle heavily shifts or brake disc external factor such as locking wheel occurs and causes wheel slipping or skid, and so this influence will be shared because of the coupled relation of two axle drive shafts.That is to say that this coupled relation helps eliminating the idle running of rolling stock or skidding.
