Embodiment Construction

[0027] Embodiments of the present invention will be described below based on the drawings. First of all, the structure of the device of the present invention is shown in Fig. 1, Fig. 2, etc. It is mainly composed of a driving side speed change pulley A, a driven side speed change pulley B and a centrifugal clutch C, etc., and an engine is added on this basis, which is called As an engine assembly. The drive side speed change pulley A is attached to the crankshaft on the engine side via a drive shaft. The drive-side variable speed pulley A is mainly composed of a movable sheave half 1 , a fixed sheave half 2 , and a centrifugal roller 4 . The movable pulley half body 1 and the fixed pulley half body 2 are opposed to form a group of pulleys. The movable sheave half 1 is formed of a substantially flat conical belt abutment plate 1a and hub 1b, and the fixed sheave half 2 is formed of a substantially flat conical belt abutment plate 2a and hub 2b.

Abstract

The present invention provides a V-shape belt automatic speed shifting mechanism which can reduce the vibration caused by the resonance of two belt wheels and has good durability in an automatic speed shifting mechanism constituted by a variable driving speed-shifting belt wheel and a driven speed-shifting belt wheel. The V-shape belt automatic speed shifting mechanism is constituted by the driving speed-shifting belt wheel A in which a centrifugal rollers 4 are installed, the driven speed-shifting belt wheel B, and a centrifugal clutch C which has equipped with centrifugal hammers 12 and which is connected to the driven speed-shifting belt wheel B. Between the number of the centrifugal rollers 4 of the driving speed-shifting belt wheel A and the number of the centrifugal hammers 12 of the driven speed-shifting belt wheel B, the ratio of the larger number to the smaller number is non-integer.

Description

technical field [0001] The invention relates to a V-belt automatic transmission, which is composed of a variable driving side speed change pulley and a driven side speed change pulley, which can reduce the vibration caused by the resonance of the two pulleys and has good durability. Background technique [0002] The set number ratio between the centrifugal roller arranged in the movable pulley of the driving (or driving) side speed change pulley and the centrifugal hammer of the centrifugal clutch arranged in the driven side speed change pulley in the V-belt automatic transmission (drive The number of centrifugal rollers of the side speed change pulley / the number of centrifugal hammers of the driven side speed change pulley) is generally an integer value. Such a structure in which the aforementioned ratio is set to an integer value is common in the prior art, and has been disclosed in many documents such as the following Patent Document 1, for example. In the case of this p...
