摘要： A sprocket assembly is disclosed for use as a drive or idler wheel for the endless tracks of a track type vehicle. Included is an inner rim rigidly and concentrically mounted to a hub and having a series of studs projecting radially outwardly therefrom at constant circumferential spacings. Each stud has fitted thereon a universal shock absorber having two or more concentric tubes of rigid material with a preloaded elastic member or members engaged therebetween. Disposed concentrically outwardly of the studded inner rim is an outer rim having a series of sprocket teeth formed on its circumference and defining an annular row of radial, inwardly open cavities to closely receive the respective shock absorbers on the studs of the inner rim. The shock absorbers damp the forces exerted between the inner and outer rims in all of the axial, radial, and rotational directions of the sprocket assembly. Preferably, a pair of annular end covers are rigidly mounted to the inner rim and are held against the opposite axial ends of the outer rim via elastic sealing members which are also effective to elastically bear the forces exerted between the inner and outer rims in the axial, radial, and rotational directions of the sprocket assembly.

摘要： A crawler-type vehicle undercarriage including a track frame, an idler, a sprocket, a crawler encompassing the idler, track rollers, and the sprocket and the idler, the sprocket and the track frame located to line up in a straight line comprising the crawler-type vehicle undercarriage comprising (i) an idler avoided from pivoting upwardly or downwardly relative to the track frame, (ii) a first arm pivotally mounted at the bottom of the track frame, and (iii) a second arm pivotally connected to end portion of the first arm. The track roller unit adjacent the sprocket is preferably pivoted about a pivot center of the first arm positioned at the bottom of the track frame and toward the idler relative to a pivot center of the second arm. The track roller travel improves a flexibility of the track roller to the crawler, and work in a high tractive force is carried out with the track rollers providing unchangeable real contact areas to the ground.

摘要： A travel gear of a crawler work vehicle has a plurality of double bogie type track wheel devices. The double bogie type track wheel devices respectively include a first arm member attached to the lower part of a track frame so as to be swingable in the vertical direction, a second arm member whose almost center portion in the longitudinal direction is rotatably attached to the tip of the first arm member, and a pair of front and rear track wheels rotatably attached to front and rear ends of the second arm member and rolling on the tread of a crawler. A pair of first guard devices for preventing intrusion of a foreign matter into a space between the pair of front and rear track wheels and the crawler are attached to both side faces in the width direction of the vehicle of the first arm member.

摘要： An operator cabin on construction equipment is provided with a supporting structure which improves the riding quality by absorbing and damping vibrations and large impacts transmitted to the operator cabin. The right and left side portions of a front portion of the operator cabin (1) are secured to a frame (3) of the body of the construction equipment through damper plate shock absorbers (10R, 10L) or rotatable mounts (30R, 30L), while the right and left side portions of a rear portion of the operator cabin (1) are secured to the frame (3) through spring biased hydraulic shock absorbers (20L, 20R). Each of the shock absorbers has a vibration damping function. In particular, the stroke of the spring biased hydraulic shock absorber is large enough to absorb a large impact energy. This makes it possible to absorb vibration of small amplitude. For a strong shock, the impact energy can be absorbed by oscillating the operator cabin (1) about a pivot axis through the front mounts, allowing damping of the vibration. Lateral oscillation can be minimized by a four-bar parallel linkage which includes upper and lower lateral bars (40a, 40b), one cabin side (1R), and a vertical bracket (4R) positioned adjacent to that cabin side (1R).
摘要翻译：施工设备上的操作员舱设置有支撑结构，其通过吸收和阻尼传递到操作员舱的振动和大的冲击来提高乘坐质量。操作员舱（1）前部的右侧和左侧部分通过阻尼板减震器（10R，10L）或可旋转安装件（30R，30L）固定在施工设备主体的框架（3）上，而操作员舱（1）的后部的右侧部分和左侧部分通过弹簧偏压的液压减震器（20L，20R）固定到框架（3）上。每个减震器都具有减振功能。特别地，弹簧偏压液压减震器的行程足够大以吸收大的冲击能量。这使得可以吸收小振幅的振动。对于强烈的冲击，冲击能量可以通过使操作员舱（1）围绕枢转轴线摆动通过前部安装件而被吸收，从而阻尼振动。横向振动可以通过四杆平行连杆最小化，该四杆平行连杆包括上和下侧杆（40a，40b），一个舱侧（1R）和与该舱侧相邻的垂直托架（4R）。

摘要： A crawler vehicle undercarriage which comprises a first cylindrical track frame pivotally mounted to a vehicle frame and a second cylindrical track frame telescopically received within the first track frame. An idler is pivotally and rotatably mounted through a cushion pad to a forward end of the second track frame while a drive sprocket is mounted to a drive shaft. A track chain encompasses the idler and the drive sprocket and is in driven engagement with the drive sprocket. A recoil spring is interposed between the first and second track frames for urging the idler away from the sprocket to maintain track tension. First and second crank members are pivotally mounted to the first track frame with a common pivot axis. A bogie is pivotally mounted to the respective crank members and a pair of track rollers are pivotally mounted to each bogie, the track rollers engaging the track chain.
