牵引车的牵引能力由拉杆牵引力定义;以牛顿(N)报价。牵引杆拉力(DBP)的两个值需要知道;从静止和连续或额定(滚动)DBP开始的最大DBP,拖拉机可以在该DBP上工作更长的时间。表面电阻(SR)也必须允许;下表以牛顿/吨牵引载荷为单位给出。对于平均计算,我们使用400 N / t的起轧和200 N / t的轧制。
拖曳拖拉机技术数据:
DBP | = | 牵引杆拉力(N) |
WT | = | 拖拉机重量(吨) |
WL | = | 牵引重量(吨) |
SR | = | 表面电阻(N /吨) |
98 | = | 转换系数 |
G | = | 梯度表示为%,例如12 1/2% |
在级别上,DBP | = | (WL x SR)牛顿 |
在渐变上,DBP | = | (WL x SR)+((WT x WL)x 98 x G)牛顿 |
英文介绍:
The towing capability of a tractor is defined in terms of drawbar pull; quoted in Newtons (N). Two values of drawbar pull (DBP) need to be known; maximum DBP for starting from rest and continuous or rated (rolling) DBP at which the tractor can work for longer periods. Surface Resistance (SR) must also be allowed for; a table is given below, in terms of Newtons per tonne towed load. For average calculations, we use 400 N/tonne starting and 200 N/tonne rolling.
Tow Tractor Technical Data:
DBP | = | Drawbar Pull (N) |
WT | = | Weight of Tractor (tonnes) |
WL | = | Weight of Towed Load (tonnes) |
SR | = | Surface Resistance (N/tonne) |
98 | = | Conversion Factor |
G | = | Gradient expressed as a % e.g. 12 1/2 % |
On the level, DBP | = | (WL x SR) Newtons |
On a gradient, DBP | = | (WL x SR) + ((WT x WL) x 98 x G) Newtons |
