Through setting up the support roof into girder and vehicle frame connecting piece, support roof stable structure, vehicle frame connecting piece's the outside and connected with the frame have reduced the occupation space of support roof, make things convenient for the installation and the arrangement of other spare parts.

Preferably, the upper end of the frame connecting piece is provided with a welding groove, and the crossbeam and the frame connecting piece are welded through the welding groove. Through setting up the welding groove, stability when having improved frame connecting piece and girder welding.

Preferably, the protective sleeve comprises a bearing sleeve and a transmission shaft sleeve, the transmission shaft sleeve penetrates into the bearing sleeve and is in transmission connection with the bearing sleeve through a bearing, and the transmission shaft is in transmission connection with the transmission shaft sleeve through a spline. The bearing sleeve and the transmission shaft sleeve are arranged, so that the transmission shaft is effectively protected, and the connection of the transmission shaft is stable and reliable.

Preferably, the two ends of the transmission shaft sleeve are further provided with check rings, one side of each check ring is further provided with a clamp spring, and the clamp springs are sleeved on the transmission shaft sleeve. Through the setting of retaining ring and jump ring, further carry on spacing fixedly to the both ends of driving shaft sleeve, improve the stability of driving shaft installation.

The utility model has the advantages that: this simple structure, simple to operate can be effective, stable support transmission shaft, guarantees the stability and the reliability of transmission shaft in transmission process, and the both sides and the connected to frame of fixed bolster have reduced the whole volume of transmission shaft support in addition, make things convenient for the arrangement and the arrangement of other spare parts of car.

The features and advantages of the present invention will be described in detail by embodiments with reference to the accompanying drawings.
