Problems solved by technology

[0010] However, when a heavy mechanical transmission is used as in the prior art small vehicle, the spring load of the suspension system increases, the ride comfort deteriorates, and a large suspension must be made to ensure that the power unit oscillates. Space body construction, therefore, runs counter to the requirements of small and simple vehicles

Embodiment Construction

[0054] Figure 1~ Figure 4 As shown, the small vehicle of this example is a four-wheeled vehicle with two front wheels 1 and two rear wheels 2 respectively, and a single driver's seat 3 in which a passenger (driver) rides in the central part.

[0055] The basic body structure of this small vehicle is that a frame-shaped body frame 4 made of a metal pipe such as aluminum is covered with a resin body cover 5 , and a resin body cover is arranged above the body cover 5 . The top plate 6 made of steel is used to cover the top of the vehicle seat 4 of the occupant to form a driver's cab.

[0056] 7 in the figure is the steering wheel, and the steering force from the steering wheel 7 is applied by the steering steering mechanism outside the figure, thereby changing the orientation of the front wheels and changing the running direction of the vehicle arbitrarily.

[0057] In addition, reference numeral 8 in the figure is a shift lever provided on the side of the seat 3, and as will b...

Abstract

This device is a power transmission device connecting a mechanical automatic transmission 44, an engine 41 and a belt type continuously variable transmission and transmitting output of the mechanical automatic transmission 44 to a differential mechanism 45 and driving a left and a right drive wheel 2. The mechanical automatic transmission 44 is an automatic transmission having a low speed gear 65b and a high speed gear 65a transmitting the output to the differential mechanism 45 and a centrifugal shifting clutch 64 connecting when an output revolution speed of the belt type continuously variable transmission rises, and selecting two speeds of the low speed gear 65b and the high speed gear 65a by connection and disconnection of the centrifugal shifting clutch 64, and has a small-sized and lightweight structure.

Description

[0001] This application is a divisional application with the application number 01112125.4, the application date being March 29, 2001, and the title of the invention being a power transmission device for a small vehicle. technical field [0002] The present invention relates to a vehicle power transmission device that transmits power from an engine to left and right drive wheels, and particularly relates to a power transmission device suitable for a small vehicle with a simple structure that can accommodate one or two people. In addition, the present invention also relates to a vehicle power transmission device that transmits power from the engine to the left and right drive wheels through a belt-type continuously variable transmission and a mechanical automatic transmission. Automatic transmission and mechanical stepped transmission are vehicle power transmission devices that transmit power from the engine to the drive wheels. Background technique [0003] In recent years, ...
