Abstract

To realize a small-sized vehicle simply operable with a reduced fuel consumption and a reduced exhaust gas amount by using a mechanical type automatic transmission in combination with a belt-type continuously variable transmission, wherein the mechanical type automatic transmission is smaller in size and lighter in weight than an automatic transmission of a planetary gear type using a large number of gears or an automatic transmission using a hydraulic control system. To satisfy performances required for both a centrifugal type starting clutch of a belt-type continuously variable transmission and a centrifugal type speed change clutch of a mechanical type automatic transmission. And to provide a power transmission system for a vehicle, which is capable of reducing the load of a speed change operation of a continuously variable automatic transmission, typically, using a V-belt by using a mechanical type stepped automatic transmission in combination of the continuously variable automatic transmission, and realizing desirable riding comfort of the vehicle without occurrence of any gear-shift shock as a whole by absorbing the gear-shift shock caused by the mechanical type stepped automatic transmission by the continuously variable automatic transmission. In a power transmission system for a small-sized vehicle, a mechanical type automatic transmission 44 is connected to an engine 41 via a belt- type continuously variable transmission 43, wherein an output from the mechanical type automatic transmission is transmitted to a differential mechanism 45, to rotate right and left drive wheels 2. The mechanical type automatic transmission 44 is an automatic transmission of a type capable of selecting a speed stage from at least two speed stages. The automatic transmission has a low speed gear 65b and a high speed gear 65a for transmitting the output from the mechanical type automatic transmission 44 to the differential mechanism 45, and also has a centrifugal type speed change clutch 64 which is engaged when the rotational speed of the output from the belt-type continuously variable transmission is increased. One of the low speed gear 65b and the high speed gear 65a is changed to the other by disengagement and engagement of the centrifugal type speed change clutch 64. With this configuration, the structure of the power transmission system is reduced in size and weight. A centrifugal type starting clutch 57, which is engaged for transmission of an engine power as the engine rotational speed is increased, is provided on the belt-type continuously variable transmission 43. A centrifugal type speed change clutch 64, which is engaged to switch a power transmission gear from a low speed gear 65b to a high speed gear 65a as the engine rotational speed is increased, is provided on the mechanical type automatic transmission 44. The centrifugal type starting clutch 57 is operated in a dry environment for allowing power transmission by engagement for a short sliding time even at a small rotational speed, and the centrifugal type speed change clutch 64 is operated in an oil lubricating environment for ensuring a sufficient durability with a small-sized structure even if a sliding time becomes longer for reducing a speed change shock. A gear-shift operation timing from a low speed gear 65b to a high speed gear 65a of the mechanical type automatic transmission is set to be overlapped to a transmission operational region C of the continuously variable transmission. By switching one of the gears of the mechanical type automatic transmission to another in a state in which the continuously variable transmission operation has a margin, a gear-shift shock is absorbed by the continuously variable transmission operation.

Moreover, 'machine-type transmissions, movable wheels are used at the same time, and the ratio can also be suppressed. [The present invention intends to change the driving mechanism from the driving wheel to the general and mechanical type, but the engine is ready. It is required to shake and reduce the weight of each body group to shake the self-driving safety gear from the top, and to drive the gear, for the purpose of increasing the exhaust, it is like a car body. Full-speed machines, units, and uniform installations are lighter and lighter. Power transmission equipment that is both cheap and lightweight has a belt-type stepless speed changer and a mechanical speed changer. The belt-type stepless speed changer and machinery transmit engine power to the drive at a wider range of speed ratios and reduce the size of the pulleys of the variable-speed winding belt burdened by the belt-type stepless speed changer. Problems to be Solved] There have been examples of using a belt type stepless speed changer in a small vehicle. Previous mechanical transmissions were either manual transmissions that were shifted as levers, or planetary transmissions, which were both large and heavy. To achieve low fuel consumption and low exhaust emissions, small vehicles have a small amount of low output power, and combined with the power of these mechanical variable-speed engines, it is not possible to achieve low-fuel consumption and other small vehicles. For the above-mentioned desired purpose, that is, to simplify the technical solutions that meet these requirements, such as the suspension structure of various parts of the vehicle, it is expected that the power system connected to the left and right drive wheels, such as a differential device, will be miniaturized. In order to construct these machines as a force unit, and if the machines are to be mounted on the vehicle, the suspension of the moving wheels of the power unit must be performed simultaneously.

Description of the invention (24)-;-When the second way is still sufficient, the second gear from the low-speed gear is used to change the slot:, and then use the stepless self-gravity shifting action Brother Yu field and absorb the shock of speed change. In view of the absorption effect of this variable speed shock, the force &quot; X will be explained in more detail as shown in Fig. U. The low speed broadcast gear 65b is used to transfer and close, and when the centrifugal starting clutch 57 is connected. The middle part B1 is generally, as the gear ratio of the engine, mining, and wind is increased, the revolution of the engine 41 is increased (N: gear 65b ", and then, if the engine speed (Ne) has exceeded a certain 'IK (V: 2 without step 1) Changing speed and moving two :: After the catch is completed, and the speed of the vehicle (v) p: 5 is automatically changed in steps, the D1 part in the figure generally 'renews with the σ1 &quot; The speed of the engine 41 (Ne), also ^ = the speed of the wheel 65b, part A in the figure is a starting sliding part., Vehicle speed (V). By the way, as mentioned above, if the power is not changed for power rotation As shown in Figure 11 (b) '-the shift state of the reverse gear 65a (v) shaft, as shown in part B2 of the figure: a gear ratio using the vehicle speed gear 6 5 a to increase the engine speed (n &amp; Through the high gear (v), and then, if the engine speed has exceeded = some two) 丄 also speed up the vehicle speed ^ part in general, it is obvious Automatic transmission = value 'as shown in the figure vehicle speed (V), and then the low speed to high speed, and at the same time speed up the operation is probably completed, and the vehicle speed (V) p: π ^ stepless automatic speed change / after a certain preset Threshold value, as in the 496932 V. Description of the invention (25) D2 in the figure, the speed of the engine 41 (Ne) is increased again through the high-speed gear teeth, and the vehicle speed is also increased ^). The dynamic transmission device of this example is still in use.

As a result, when the belt 53 receives the transmission tension and rotates the passive pulley 52, it acts on the movable plate 52b. The lateral pressure of the belt 53 is equal to the sum of the pressing force from the pull-back spring 52c and the component force caused by the cam groove 82, and by increasing the pushing contact force of the movable plate 5 2b to the belt 53, The transmission efficiency between the belt and the pulley is improved. Furthermore, in the prior art, as described above, the gear shift from the low-speed gear 65 5b to the high-speed gear 65a is performed, so that the passive pulley 52 side (that is, The crankshaft 49 side) reduces the speed, thereby greatly shifting to the direction in which the engine speed is reduced, so that a shift shock occurs. = 'In this example', when the gear shift from the low gear _ to the high gear 6 5 a is performed When it is used carefully, it will increase the rotation of the belt 53 households ^ =; ^ =, the low component force caused by the slanted cam ，, move the direction of the fixed plate 52a, and then The belt cymbals are moved close to the solid low ratio side, which can make the crankshaft rotate at 49 rpm.
