Problems solved by technology

[0002] For a simple centripetal turbine torque converter with three working wheels, its high-efficiency range is very narrow, and the efficiency in low-speed and high-speed areas is very low, while automobiles and engineering vehicles require a wide range of work, which cannot be guaranteed in the torque converter. Working in a high-efficiency range reduces the average efficiency of the transmission, deteriorates the economy, and brings higher heat dissipation requirements

Embodiment Construction

[0026] see figure 1 with Figure 5 , The wet clutch for the automobile torque converter of the present invention includes a housing 1, a driven plate 2 (ie, a piston disc), a cage 3, and a paper-based friction plate 5. The driven plate 2 and the cage 3 are connected by rivets 4 . The cage 3 forms a spring installation space, and the pre-compression of the large spring 6 is adjusted through the spring pad 8 .

[0027] The driven plate 2, the spring pad 8, the cage 3, the rivet 4, the friction plate 5, the large spring 6 and the small spring 7 form a locking clutch assembly, wherein the circular paper-based friction plate 5 is bonded on the driven plate and Form a friction pair with the housing 1, combine and separate. The shell is low carbon steel material. The paper-based friction plate adopts a whole ring structure, which is bonded with the driven plate, and the structure is reliable. Coefficient of friction: 0.12, thickness 1. see Figure 4 .

Abstract

The invention relates to a wet lockup clutch for hydraulic torque converters. The clutch comprises driven plates, holding racks, a spring assembly, rivets, friction plates and a friction couple combination shell. The holding racks are riveted with the driven plates by the rivets, and spring pads are added to form the spring installation space, 8 groups of springs are uniformly distributed in the tangential direction, and the friction combination surface is in the relative bevel structure. A hydraulic torque converter can stably contact with the clutch under the operation condition of low pressure and high speed, the combination torque is large, the reaction speed is quick, the shock absorption effect is remarkable, and the ride comfort and the fuel economy are improved.

Description

technical field [0001] The invention relates to a lock-up clutch for an automobile hydraulic torque converter. Background technique [0002] For the simple centripetal turbine torque converter with three working wheels, its high-efficiency range is very narrow, and the efficiency in the low-speed and high-speed areas is very low, while the working range of automobiles and engineering vehicles is very wide, which cannot be guaranteed in the torque converter. Working in the high-efficiency range reduces the average efficiency of the transmission, deteriorates the economy, and brings higher heat dissipation requirements. [0003] In order to expand the high-efficiency range of the torque converter, a comprehensive hydraulic torque converter in which the guide wheel can be automatically wedged and loosened appears. When the speed ratio is high, the guide wheel idles, which improves the efficiency in the high speed ratio area. Only around 80-85%. [0004] In recent years, the a...
