Embodiment Construction

[0016] Principle of the present invention, structure, working process and specific implementation mode will be further described below in conjunction with accompanying drawing:

[0017] figure 2 and image 3 A schematic diagram of the self-adaptively adjusted friction plate structure provided by the present invention, the friction plate structure includes a main connecting piece 1, a saddle 2 connected to the main connecting piece 1, and a multi-layer metal transmission steel belt ring 5 sleeved on the saddle; The left and right sides of the saddle are respectively provided with rotating lugs 3, and the rotating lugs are connected with the saddle through the lug shaft 4 arranged on the saddle.

[0018] In order to facilitate installation and processing, the saddle can adopt two saddles arranged symmetrically front and back, and the rotating lug 3 is made into a "convex" shape, which is composed of two parts, the lug support 11 and the lug end 12, and the lug support 11 is ar...

Abstract

A friction plate mechanism of the adaptive control used for the steepless gear relates to a drive friction plate device used in the metal tape (chain) type steepless gear, wherein the friction plate mechanism has a main connection strap, a saddle piece connected with the main connection strap and multilayer metal drive metal strip ring sleeved on the saddle piece; the left side and the right side of the saddle piece are arranged with drive ear piece connected with the saddle piece through the ear shaft on the saddle piece. Due to the drive ear piece on the left side and the right side, the contacting area of the metal driving belt (or chain) and the pan is increased, wherein the cone bus is a straight line and the contacting pressure is even; moreover, the driving ear piece can self-adaptive control the fraction joint angle to reduce the effect brought by the driving belt (or chain), which makes the self-adapting adaptability of the contact increase.

Description

technical field [0001] The invention relates to a transmission friction plate device used in a metal belt (chain) type continuously variable transmission, belonging to the technical field of mechanical transmission. Background technique [0002] Transmissions include manual transmissions, automatic transmissions, and continuously variable transmissions; for manual transmissions, since the number of teeth in each gear set is fixed, the gear ratio of each gear is a fixed value (that is, the so-called "stage"), for example, for As far as cars are concerned, the first gear ratio is 3.455, the second gear is 2.056, and then the fifth gear is 0.85; these numbers are multiplied by the main reduction ratio to get the total transmission ratio, and there are only 5 values ​​in total (that is, there are 5 levels), so Say it is a stepped transmission. For the automatic transmission, it uses the vehicle speed and load (accelerator pedal stroke) for dual-parameter control. It is also a s...
