Description

一种箱式卡车箱体伸缩遮盖物的传动离合装置 技术领域
本实用新型涉及一种传动技术领域，具体是一种箱式卡车箱体伸缩遮盖物的传动离合装置。
背景技术
传统的皮卡型货车利用车厢来携带不同的货物，同时车厢被一个智能电动尾箱盖所覆盖，以便保护所运载的货物不被天气环境影响，不会被偷盗，同时皮卡货车外观也更加美观。现有市面上的皮卡车的智能电动伸缩尾箱盖传动离合结构是用一个内六角套筒连接马达主轴和卷帘主轴，其中马达主轴和卷帘主轴为正六边形主轴。当内六角套筒套在马达主轴和卷帘主轴时可以实现动力传递，从而实现电动卷帘的开合；当移动内六角套筒使其脱离马达主轴时，中断了马达主轴的动力传递，此时电动尾箱盖可以手动地进行开合。
上述实施方案在尾箱盖不能正常开合时(如系统电源系统故障)，由于内六角套筒因接触面积大，且马达主轴在旋转时对六角套筒和卷帘主轴施加的力依然存在，使得在移动内六角套筒时非常困难。同时当需要解除异常，需要将内六角套筒移动到马达轴上时，同样由于接触面大，且在不能目视的情况下，需要较强的专业动手能力方可完成复杂的操作。不仅如此，电动尾箱盖安装在皮卡车厢上后，当线路发生异常或者汽车电瓶没电无法正常提供电力驱动马达转动或马达损坏时，尾箱盖将无法打开，严重影响货箱的正常使用。为了解决以上弊端，急需提出一种箱式卡车箱体伸缩遮盖物的传动离合装置。

所述的马达轴齿轮、卷帘轴齿轮、中间轴齿轮均为扇形齿轮。
所述的中间轴的任意一端面设置有旋转十字槽。
所述的齿轮箱呈矩形，马达轴齿轮及卷帘轴齿轮横向安装在齿轮箱内，中间轴及中间轴齿轮纵向安装在齿轮箱内。

当出现异常情况无法正常使用尾箱盖时或需要中断动力传递时，同样利用专用工具反向旋转中间轴一端的旋转十字槽，使得中间轴齿轮与马达轴齿轮及卷帘轴齿轮脱离，便可切断马达轴齿轮与卷帘轴齿轮的连接。通过移动中间轴齿轮便可实现中断动力传递的目的，此时，用户即可通过手动操作打开或是关闭遮盖尾箱盖，方便在紧急情况下进行装卸货，具有结构简单，操作轻巧方便，不需要用户使用很大的力气便可使得马达轴齿轮与卷帘轴齿轮分离。
与传统技术相比，本传动离合装置通过改变中间轴齿轮与马达轴齿轮及卷帘轴齿轮间的相对间隙，从而实现切断或连接马达轴齿轮与卷帘轴齿轮间的啮合传动，具有结构简单，操作快捷，操作效率高，不需要专业的技术人员和专业的工具便可实现，利于推广使用等优点。
以上显示和描述了本实用新型的基本原理和主要特征和本实用新型的优点。本行业的技术人员应该了解，本实用新型不受上述实施例的限制，上述实施例和说明书中描述的只是说明本实用新型的原理，在不脱离本实用新型精神和范围的前提下，本实用新型还会有各种变化和改进，这些变化和改进都落入要求保护的本实用新型范围内。
