The utility model discloses a semi-caterpillar three-wheeled building climbing substitute bicycle, which comprises a frame, a front wheel installed on the front-end shock absorption fork of the frame, a rear axle connected with the drive rear axle under the frame by a shock absorber on the left and right sides of the rear axle, and a rear wheel installed on the front wheel, a front electric brace rod installed on the front fork of the shock absorption, and the other end connected with the front crawler. The front part of the driving rear axle is connected with the rear part of the driving rear axle; the rear part of the driving rear axle and the rear part of the driving rear axle are connected with connecting rods; the rear part of the driving rear axle is connected with the driving rear axle at one end and the other end is connected with the rear part of the driving rear part; the rear part of the driving rear axle is driven by lowering the rear part of the driving track when the road condition is not good. Drive, so that you won't get stuck and skid, especially when the front and rear track devices are put down, they can go up and down stairs as smoothly as if they had built a bridge board.
【技术实现步骤摘要】
半履带式三轮爬楼代步车
本技术涉及一种代步装置,尤其是一种三轮代步车。
技术介绍
现有的三轮代步车是以一个前轮控制方向,左、右两后轮驱动行驶的车,这种以车轮驱动行驶的车存在着缺陷,因为驱动轮触地面积小,摩擦力小,在泥泞的路、雪地等路况不好时容易陷车、打滑,再由于车轮直径小,遇到过街天桥等有台阶的就上不去、过不了,住在楼房上的也爬不上楼。
技术实现思路
为了克服现有的三轮代步车在泥泞的路、雪地等路况不好时容易陷车、打滑,遇到过街天桥、楼梯等爬不上的缺陷,本技术提供一种半履带式三轮爬楼代步车,采用在普通三轮代步车的前、后轮上安装可收上和放下的履带装置,在路况不好时放下两后履带装置驱动行驶,这样就不会陷车、打滑;前、后履带装置放下后就像搭了桥板一样能顺畅的上、下楼梯。本技术解决其技术问题所采用的技术方案是;一种半履带式三轮爬楼代步车,包括车架,车架前端减震前叉上安装前轮,车架后部的左、右以减震器与车架下面的驱动后桥连接,驱动后桥的左、右两头各安装一后轮;前轮上安装一前履带装置,前电动撑杆一头安装在减震前叉上,另一头与前履带装置的前部连接;驱动后桥两后轮的外侧各安装一后履带装置, ...
【技术保护点】
1.一种半履带式三轮爬楼代步车,包括车架,车架前端减震前叉上安装前轮,车架后部的左、右以减震器与车架下面的驱动后桥连接,驱动后桥的左、右两头各安装一后轮,其特征是:前轮上安装一前履带装置,前电动撑杆一头安装在减震前叉上,另一头与前履带装置的前部连接,驱动后桥两后轮的外侧各安装一后履带装置,后履带装置从主动轮向后伸展,左、右后履带装置的尾部以连接杆连接;后电动撑杆一头与驱动后桥连接,另一头与后履带装置的尾部连接杆连接。
