摘要： Right and left track adjusters each comprise a tension adjusting cylinder operable in forward and backward directions in the same condition; a motor-driven hydraulic pump; and a direction selector valve disposed in a hydraulic circuit for connecting the motor-driven hydraulic pump to the tension adjusting cylinder. The hydraulic circuit includes operating condition detecting means for detecting the operating condition of the tension adjusting cylinder. A controller located in the work vehicle judges a signal released from the operating condition detecting means. If the pressure condition is determined to be higher than a preset value, the tension adjusting cylinder is moved backward to avoid abnormal tension in the crawler belt. If it has a steady-state value, the movement of the tension adjusting cylinder is controlled according to a judgment based on a set value corresponding to the traveling direction of the vehicle, thereby properly adjusting the tension of the crawler belt.

摘要： The invention provides a shaft for a roller wheel which is excellent in strength and can achieve a weight saving. The invention provides a shaft for a roller wheel which rotatably supports a roller (3) outward fitted between both end portions (5a, 5b) in a state in which both end portions (5a, 5b) are fixed, and receives a load in a diametrical direction via the roller (3). Recess portions (6, 6) are provided on a side to which the load is not applied, on an outer peripheral surface corresponding to the roller (3). The load applying direction is a vertical direction. A cross sectional shape of the shaft in the recess portions (6, 6) is formed in a shape which is constituted by an upper circular arc portion (10) on an upper side, a lower circular arc portion (11) on a lower side, and a vertical connection portion (12) passing through a shaft axis (O) and connecting the upper circular arc portion (10) to the lower circular arc portion (11).

摘要： An equalizer bar itself serving as a suspension device of a track-type vehicle has spring effects imparted through torsional deformation relative to vertical oscillatory movements of track frames. Arm portions are fixed in directions opposite to each other in two ends of an equalizer bar main body. Free end portions of the arm portions are individually supported in the track frames to be rotatable in directions opposite to each other. The track frames are therefore regulated in the magnitudes of oscillatory movements according to the spring effects of the equalizer bar main body, whereby travel-time oscillations, oscillatory movements, and/or the like of the vehicle body are sufficiently restrained.

摘要： In a crawler belt comprising pairs of opposite links connected endlessly via pins press-fitted into the links, fixing surfaces of pins or links are successively pressed and deformed from the fixing surfaces in an axial direction along the circumferences inside or outside of openings of pin-press-fitting holes by means of local pressing in the axial direction, whereby the end portions of the pins or part of the circumferences of the openings in the links are expanded or narrowed in diameter. The expanded or narrowed portions are fixedly engaged with the opposing engaging spaces. The surface hardness of the expanded or narrowed portions is set to be lower than that of the other portions. With such structure and method, the links and pins can be easily and firmly connected with sufficient holding force in the axial direction, securing accurate, quick and easy fixing of pins and assembling of pins and links.
