轮胎压路机的原后轮驱动装置中的4个轮胎分为左右两组,每组采用液压驱动,相对后轮架为简支式布置,两个轮胎的轮辋设计为一个整体。这种结构的减速机受力状况比较好,压路机的自重能够比较均匀地通过简支结构传递到轮胎上,但检修及维护极为不方便,更换轮胎时,拆装的零部件很多,很容易在维修过程中产生新的故障。新后轮驱动装置中的4个轮胎等距布置分为3组,中间两个为一组,左右两个分别为一组。左右两组采用液压马达驱动减速机后,再通过辐板直接驱动侧轮轮辋,中间组通过中间轮轮辋的辐板安装在后轮架上。左右组与中间组通过带花键的连接件连接,保证4轮同时得到驱动力,3组轮胎组件与后轮架简支相连。后轮架由原来的两个变成一个,用螺栓组与轮胎压路机的箱体式车架相连。这种结构更换轮胎简单,更换中间轮,只需要拆开轴固定座及连接件;更换两个侧轮时,在推出中间轮后可以直接拆卸,而且更换任何一个侧轮都不需要拆卸减速机、液压马达等部件,节省时间而且减少了产生新故障的可能,有利于提高系统的可靠性和维修的方便性。
The four wheels of the original rear wheel drive of the tire road roller are divided into two groups of left and right, each of which is driven hydraulically and the rear wheel frame is arranged in a simply supported manner, and the rim of the two tires is designed as a whole. This structure of the reducer stress situation is better, the roller weight can be relatively simple through the simple structure of the transmission to the tire, but overhauling and maintenance is extremely inconvenient to replace the tires, the disassembly of many parts, it is easy to A new failure occurred during maintenance. The 4 rear tires in the new rear wheel drive are equidistantly arranged into 3 groups with two in the middle and one in each of the two left and right groups. Left and right two groups of hydraulic motor drive reducer, and then through the web directly drive the side wheel rim, the middle group through the middle wheel rim web mounted on the rear wheel carrier. The left and right groups are connected with the middle group through the splined connecting pieces to ensure that the four wheels receive the driving force at the same time, and the three sets of tire components are connected with the simple support of the rear wheel frame. The rear frame from the original two into one, with the bolt group and the road roller box body frame connected. This structure is simple to replace the tire, the replacement of the intermediate wheel, only need to disassemble the shaft holder and the connector; replace the two side wheels, after the introduction of the intermediate wheel can be directly demolished, and replace any side wheel do not need to remove the reducer , Hydraulic motors and other components, save time and reduce the possibility of a new failure, help to improve system reliability and ease of maintenance.
