Hollow shaft is fixed on the main truss; Wheels are sleeved on the hollow shaft, and wheels are the standard industry rubber wheel; Axle drive shaft is connected by key with the driving flange by the bearings in the hollow shaft; Between axle drive shaft and the reducing motor brake disc is housed, brake disc is connected key to connect with axle drive shaft; Reducing motor is installed in the main truss side by antitorque support, and the output torque of reducing motor is delivered to by axle drive shaft and drives on the flange.
Preferably, between the installation shaft of antitorque support and reducing motor rubber coating is housed.
Preferably, adopt interference fit to connect between hollow shaft and the main truss.
Preferably, drive between flange and the axle drive shaft and adopt spline joint, the fixed form that adopts bolt to add locating dowel pin between the wheel hub connects.
Preferably, drg adopts air or electric liquid to drive.
Preferably, antitorque support is the box beam structure.
The utlity model has following beneficial effect:
1, the application provides a kind of industrial reductor of standard of using as the technical solution of single track sightseeing train traction reducing motor, introduced the brake system that is independent of motor braking, introduced the back axle bearing technology of automobile, stationarity and the reliability of failure to the safe side wheel have been improved, avoided because developing technical risk that special gear case produces and the cost issues of great number, thereby reduced the cost of technology and the manufacturing, reduce maintenance difficulty, played certain energy-conserving and environment-protective effect thereby reduced enterprise energy consumption
2 compare with existing single track Sightseeing Bus, the application has introduced the automobile axle shaft structure, propulsive effort and bearing capacity are acted on respectively on the different axles: the train load is to hollow shaft, and drive torque transmits by axle drive shaft, this structure reduces axle drive shaft, thereby for reducing the size of reducing motor, for Application standard industry reductor replaces special reductor to create condition.
3, the application has introduced also independently that thereby brake unit has improved deceleration and stopping performance greatly; Because reductor is to be connected on the framework by the antitorque support with rubber coating, what its location was leaned on is axle drive shaft, thereby the output shaft of reductor and the right alignment problem between the axle drive shaft have been solved, and because of the resiliency of rubber coating with and flexible, greatly reduce the suffered impulsive force of reductor in the motion process and the position accuracy demand of installation.
Except purpose described above, feature and advantage, the utility model also has other purpose, feature and advantage.The below is described in further detail the utility model with reference to figure.
