汽车、轮式拖拉机和自行轮式工程机械等,均需有差速装置。国内目前采用伞齿轮差速器比较普遍。现介绍一种自锁式牙嵌差速器,其特点是结构简单;既是差速器又是自动差速锁,当一个驱动轮滑转时,可将扭矩传给不滑转的驱动轮。伞齿轮差速器,从其作用原理及运动学分析可知,当两轮子差速运动时,受运动阻力大的一侧轮子速度将逐渐减小,另一侧速度将增加。这时差速器分配给转速慢的轮子的扭矩比较大。当一侧轮子陷在泥坑里产生打滑时,该轮将以两倍差速器壳的转速运转,而另一侧轮子速度为零,这时整个车辆失去了驱动能力。因此,为解决上述问题,该类型的差速器必须
Vehicles, wheeled tractors, and self-wheeled construction machines require differential devices. Domestic adoption of bevel gear differentials is common. Now we introduce a self-locking type of dental differential, which is characterized by a simple structure; it is a differential and an automatic differential lock. When a drive wheel slides, it can transmit torque to a non-slip drive wheel. The bevel gear differential, from its principle of action and kinematics analysis, knows that when the two wheels move at a differential speed, the speed of the wheels on the side where the resistance is large will gradually decrease, and the speed on the other side will increase. At this time, the torque assigned to the slow-rotating wheels of the differential is relatively large. When one side wheel slips into a mud pit and slips, the wheel will run at twice the speed of the differential case, while the other side wheel speed is zero, at which point the entire vehicle loses drive capability. Therefore, to solve the above problem, this type of differential must be
