Description

一种车辆变速差速装置
本发明涉及各种车辆根据需要改变速度并可进行限滑差速的装置。
目前，公知市场上常用的车辆变速是以改变输出、输入的传动比来实现的，但这种变速机构的变速需要换档机构，需要液压装置，电子设备，且机械结构复杂。
本发明提供不需要改变输出、输入的传动比来进行变速的一种车辆变速差速装置来改善上述所提的缺点，且能进行限滑差速。
本发明是这样实现的，包括动力盘、动力轴、传动轴、齿圈、传动轴承、传动万向节、万向节轴承、固定轴承座、输出轴、动力万向节。动力轴固接在动力盘中心，在动力盘上不在中心处装有传动轴承，并通过传动轴承和传动轴连接，传动轴另一边连接传动万向节，传动万向节上有万向节轴承，并装在固定轴承座中，传动万向节上连有输出轴。也可以在动力盘和传动轴之间装动力盘万向节。
为了进行变速和限滑差速，将上述所提的装置的两个动力盘通过齿圈连接在一起，两个动力盘上各自的传动轴、传动万向节、输出轴的连接，通过万向节轴承穿过互对面的动力盘中心，再经过两固定轴承座输出。
图1为本发明的结构图
图2为本发明的装配图。
图3为本发明使用动力盘万向节的结构图。
图4为本发明使用动力盘万向节的装配图。
图5为本发明将图1的两个装置用齿圈组合一起的结构图
下面根据附图进一步说明。
在图1、图2、图3、图4、图5中，1动力盘、2动力轴、3齿圈、4传动轴承、5传动轴、6传动万向节、7万向节轴承、8固定轴承座、9输出轴、10动力盘万向节、A-A为传动轴(5)中心线、B-B为动力盘(1)中心到万向节轴承(7)中心连线。
动力盘(1)中心固接动力轴(2)，动力盘(1)上不在中心处装有传动轴承(4)，传动轴承(4)连接传动轴(5)，传动轴(5)的另一边连接传动万向节(6)，传动万向节(6)上装万向节轴承(7)，万向节轴承(7)装在固定轴承座(8)中，传动万向节(6)连接输 出轴(9)。也可以在动力盘(1)上传动轴承(4)和传动轴(5)之间装动力盘万向节(10)。
为了进行变速且能限滑差速，将前面所述的装置上的两动力盘(1)通过齿圈(3)连接在一起，两动力盘(1)上各自的传动轴(5)、传动万向节(6)、输出轴(9)的连结，通过万向节轴承(7)穿过互对面的动力盘(1)的中心，再经过两固定的轴承座(8)输出。动力轴(2)上的齿轮和齿圈(3)啮合。
当发动机不输入动力及动力盘(1)不动，车辆在惯性作用下保持行驶状态，车轮带着输出轴(9)转动，并通过传动万向节(6)使传动轴(5)绕自身中心线A-A自转。
当发动机输入动力，动力盘(1)克服车辆阻力转动，则带动转动轴(5)绕着动力盘(1)中心到万向节轴承(7)中心连线B-B公转。
传动轴(5)的自转和公转的叠加，使输出轴(9)转速增加，输出轴(9)转速增加，则传动轴(5)的自转和车辆的速度也增加，传动轴(5)公转和自转再叠加，输出轴(9)转速再增加，即动力盘(1)以一定的转速转动，输出轴(9)的转速会越来越高，及车辆的速度会越来越快(需满足提供的动力能克服车辆的阻力)，一定时间后就会达到所需要的车辆速度，如果需降低车辆速度则不给动力盘(1)提供动力或刹车，从而达到变速的目的。
在图5中，当动力轴(2)和齿圈(3)转动，带着两互对面的动力盘(1)转动，组合在一起的两传动轴(5)没有连接在一起，其自转的转速不一定相等，转弯时阻力大的一边自转转速会降低形成差速。转动轴(5)公转，整个装置为一整体，当一边打滑或悬空时，两边转动轴(5)公转转速不会变化，其公转的转速还等于动力盘(1)的转速，因此阻力大的这边的转动轴(5)和输出轴(9)就会增加扭矩，起到限滑的作用。
