摘要： In a snowmobile drive train the variable ratio belt drive is not directly coupled to the engine crankshaft as in the prior art, but rather the driving pulley of the variable ratio belt drive is carried on one end of a jackshaft and the engine power is applied to the opposite end of the jackshaft. The jackshaft is supported in a fixed bearing in the vehicle frame, this bearing being immediately adjacent to the driving pulley so that the influence on the belt drive of vibrations generated by the engine is vastly diminished. Therefore the engine mounts can be arranged to fully absorb vibrations of the engine. Previously, when the driving pulley was directly coupled to the engine crankshaft it was necessary to include a tie restraint to limit movements of the engine housing in the direction of separation between the axes of the driving and driven pulleys.

摘要： This invention relates to an improved snowmobile drive train configuration arrangement that incorporates a fixed ratio speed reduction mechanism directly coupled to the engine crankshaft. This mechanism is in turn coupled to the driving pulley of a variable ratio belt drive system, the driven pulley of which is mounted on the axle of the sprocket wheels that drive the snowmobile track. Interposing the reduction drive between the engine and the belt drive system reduces the operational speed of both the pulleys and the belt, which proves beneficial from several aspects: the mechanical efficiency of the global system is increased, the dynamic response of the transmission to throttle modulation is improved; aerodynamic losses are reduced; the bending vibrations of the crankshaft are no longer transmitted to the drive clutch; and the engine can be run at higher RPM without decreasing the efficiency of the belt drive system.
摘要翻译：本发明涉及一种改进的雪地车传动系配置装置，其结合直接联接到发动机曲轴的固定比例减速机构。该机构又耦合到可变比皮带传动系统的驱动皮带轮，其从动滑轮安装在驱动雪地车道的链轮的轴上。在发动机和皮带传动系统之间插入减速驱动可以降低皮带轮和皮带的运行速度，这从以下几个方面证明是有益的：全球系统的机械效率提高，传动装置对动力响应的调节改善了空气动力学损失减少; 曲轴的弯曲振动不再传递到驱动离合器; 并且发动机可以以更高的RPM运行，而不降低皮带传动系统的效率。

摘要： An abrasive member for surfacing a workpiece by rotary abrasion under a flow of liquid, comprises a base and a plurality of abrasive segments protruding from the base. The abrasive segments are shaped and arranged in spaced relation to one another so as to form a network of intersecting primary and secondary channels, the secondary channels cooperating with the primary channels to effect substantially complete scavenging of detritus by centrifugal drainage of waste liquid carrying the detritus through both the primary and secondary channels to the outer periphery of the arrangement of abrasive segments. Each abrasive segment has a planar working surface for abrading contact engagement with the workpiece and a bevelled leading edge which defines a sloping abrasive surface permitting the abrasive segments to ride up over surface irregularities protruding from the workpiece during rotation of the abrasive member, whereby the sloping abrasive surface cooperates with the working surface to grind the surface irregularities without causing chipping of the workpiece.
