Embodiment Construction

[0020] The specific implementation will be described below in conjunction with the accompanying drawings.

[0021] Such as figure 1 As shown, the outer star wheel type one-way clutch in this embodiment includes an outer star wheel assembly, a roller 3 , a folding spring 4 , and an inner ring 2 .

[0022] Such as figure 2 image 3 As shown, the outer star wheel assembly is a split structure, which includes the outer star wheel 1 and the baffle plate 5. Several equally spaced raceway surfaces 11 are arranged on the inner side of the outer star wheel 1, and the baffle plate 6 is located on two opposite sides. Between adjacent raceway surfaces 11. One end of the baffle plate 5 has a radially protruding mounting portion 51, so that the shape of the baffle plate 5 is roughly L-shaped, and the end surface of the outer star wheel 1 is provided with a mounting groove 12, and the mounting portion 51 on the baffle plate 5 is located in the mounting groove The mounting part 51 and th...

Abstract

The invention relates to an external star wheel type one-way clutch. The external star wheel type one-way clutch aims to solve the problem that an existing roller column type one-way clutch is high inmachining cost and low in machining efficiency. The external star wheel type one-way clutch is provided, the clutch comprises an external star wheel assembly, roller columns, folding springs and an inner ring; the device is characterized in that the external star wheel assembly is of a split structure and comprises an external star wheel and baffles; a plurality of equally spaced raceway surfacesare arranged on the inner side surface of the external star wheel; the baffles are arranged between every two adjacent raceway surfaces; a mounting part with a radial protrusion is arranged at one end of the baffles; mounting grooves are formed in the end surface of the external star wheel; the mounting parts are arranged in the mounting grooves and are fixedly connected with the external star wheel through fasteners; the inner ring and the external star wheel are coaxially installed; the roller columns are arranged between each raceway surface and the inner ring; the folding springs are arranged between each roller columns and the baffles at the large end of the adjacent raceway surfaces. The external star wheel type one-way clutch is easy to machine and low in machining cost.

Description

technical field [0001] The invention relates to a clutch, and more specifically, relates to an outer planet wheel type one-way clutch. Background technique [0002] Most loaders use a mechanical-hydraulic transmission device, that is, a hydraulic torque converter is installed between the engine and the gearbox. The loader using this device has a stable start, good acceleration performance, and can achieve a wide range of stepless transmission. The variable speed can also automatically adapt to the change of the external load of the loader, which can reduce the number of gears in the gearbox and reduce the labor intensity of the driver and operator. However, the disadvantage of hydraulic transmission is low efficiency. The highest transmission efficiency is generally about 85%. Add a one-way clutch device to realize the single-stage and two-phase functions of the hydraulic torque converter, that is, in the low-speed ratio area, the one-way clutch is locked, and the hydraulic...
