Problems solved by technology

[0003] The main disadvantages of the hydraulic torque converter are complex structure, high cost, large mass, and due to the existence of hydraulic loss, the transmission efficiency of the machine is reduced, so the fuel economy and traction efficiency of the machine are reduced
To solve this problem, some cars have a lock-up clutch on the torque converter to improve the transmission efficiency, but the complicated system and expensive transmission parts have always been the main headaches for the repair market and users

Embodiment

[0046] Example: see Figure 4 , a friction torque converter, including an inner ring 1, a large roller 2 and an outer ring 3, wherein:

[0047] The inner ring 1 is an input unit. At least two concave grooves 101 are evenly distributed on the peripheral side of the inner ring to form an inner ring cam. Each concave groove corresponds to a large roller. Figure 4 3 concave grooves and corresponding large rollers 2 are set in the middle;

[0048] The outer ring 3 is the output unit. The outer ring 3 is set outside the inner ring 1 and arranged coaxially with the inner ring 1. The inner peripheral surface of the outer ring 3 forms the inner raceway of the outer ring and is press-cut with each roller. Here The pressure cut means that the roller surface is pressed against the inner raceway of the outer ring. Since the roller and the outer ring are both arc-shaped surfaces, the two must be tangentially pressed;

[0049] The large roller 2 is arranged between the inner ring and the ...

Abstract

The invention discloses a friction type torque converter. The friction type torque converter comprises an inner ring, large rolling columns and an outer ring, wherein the inner ring is an input unit; the peripheral side ring surface of the inner ring is uniformly provided with at least two grooves; each groove is corresponding to one large rolling column; the outer ring is an output unit, coats the inner ring, and is coaxially arranged with the inner ring; and the inner side peripheral surface of the outer ring is provided with an outer ring inner rolling way to fit each rolling column. When the rotating speed and the load are changed, the rolling columns realize self-adaptive work under the coaction of centrifugal force and an inner ring cam to finally realize the locking output, the automatic speed change and torque conversion of the friction type torque converter so as to satisfy different applications. The torque converter has such advantages as simple structure, high transfer efficiency, stepless speed change, high self-adaptability, automatic locking, energy conservation and environmental protection.

Description

technical field [0001] The invention discloses a friction torque converter, which can realize a transmission system with stepless speed change and automatic torque change. Background technique [0002] At present, the most widely used torque converter is a hydraulic torque converter, also known as a torque converter, which is installed between the engine and the transmission, and uses hydraulic oil (ATF) as the working medium to transmit torque, change torque, change speed and The role of clutch. It is a non-rigid torque converter with liquid as the working medium. It is one of the types of hydraulic transmission and is widely used. The hydraulic torque converter is composed of pump wheel, turbine and guide wheel, etc. The hydraulic torque converter not only increases the torque of the engine, but also realizes the flexible connection between the engine and the automatic transmission, which effectively solves the problem of the engine The flameout problem can realize autom...
