摘要： A pin assembly (112) suitable for mounting a track roller bogie (5) on a track frame (1) of a crawler type traveling apparatus, wherein first to third rings (114 to 116) are disposed on an outer peripheral surface of a pin (13) having lubricant supply passages. Sealing means (18, 19) are disposed between end faces of the respective rings (114 to 116) and end faces other than those of the sealing means (18, 19) are formed in slide contact faces (114b, 115b; 115c, 116b), which slidably direct contact with each other. As compared with a conventional case in which spacers are installed between the first to third rings, the total wear amount of the slide contact faces is remarkably reduced, the number of parts is reduced by abolishing the conventional spacers which caused defective lubrication, and a load between the rings in a thrust direction is directly received between the rings. As a result, the troublesomeness of an assembly of the track roller bogie and a reduction in service life due to defective lubrication can be eliminated.
摘要翻译：一种适于将履带式转向架（5）安装在履带式行驶装置的履带架（1）上的销组件（112），其中第一至第三环（114至116）设置在销的外周表面上（13）具有润滑剂供给通道。密封装置（18,19）设置在各个环（114至116）的端面之间，并且除了密封装置（18,19）的端面之外的端面形成在滑动接触面（114b，115b; 115 c，116b），其彼此可滑动地直接接触。与在第一至第三环之间安装间隔件的常规情况相比，滑动接触面的总磨损量显着降低，通过消除导致润滑不良的常规间隔件减少部件数量，并且负载环之间的推力方向直接接在环之间。结果，可以消除滚轮转向架的组装麻烦和润滑不良导致的使用寿命降低。

摘要： A drive assembly for a track-type vehicle which makes the effective ground contact length within the tumbler distance as large as possible. The drive assembly has a single track roller unit disposed closest to the idler and closest to the sprocket respectively, each for supporting the track roller rotatably at the distal end portion of an arm attached at its proximal end portion rockably to the track frame and for bearing a vehicle body load at the distal end portion of the arm through elastic members, and a double track roller unit interposed between the single track roller units and including a first arm attached at its proximal end portion to the track frame and a second arm attached at its central portion to the distal end portion of the first arm, for supporting the paired lower rollers at the two end portions of the second arm.

摘要： A track roller bogie is pivotally supported by a pin assembly, in which a spacer for receiving a thrust load is abolished and the thrust load is supported by outer rings of the pin assembly themselves. It makes possible to assemble a pin assembly easier and to elongate a service life of the track bogie.
