Crab walking four-bar mechanism, crab walking four-bar mechanism device and road roller
The invention provides a crab-running four-bar mechanism, device and road roller, the crab-running four-bar mechanism is used for connecting a front frame with a rear frame, stepped connecting rods, arch-shaped connecting rods and crab-running shafts, the crab-running shafts are rotatably connected with the rear frame, the two crab-running shafts are distributed on two sides of the rear frame, the two crab-running shafts are respectively connected with the end parts of the arch-shaped connecting rods through the stepped connecting rods, and the arch-shaped connecting rods are connected with the rear frame through the stepped connecting rods. The crab-running mechanism further comprises a crab-running oil cylinder, and the crab-running oil cylinder is used for driving the arch-shaped connecting rod to move left and right relative to the rear frame, so that the front frame is driven to move left and right to form crab-running movement of the front frame and the rear frame. The two ends of the arch-shaped connecting rod are connected with the front frame through steering oil cylinders respectively, and the steering oil cylinders are used for driving the front frame to steer. The device further comprises a steering shaft, a swing shaft and a swing frame. The structure of the road roller hinged crabbing mechanism is optimized, so that the length of the whole set of crabbing mechanism is greatly shortened, interference of crabbing on the steering angle in the crabbing process is avoided, and the complete steering angle in the crabbing state is achieved.
本发明提供一种蟹行四连杆机构、装置及压路机，蟹行四连杆机构用于连接前车架和后车架，阶梯连杆、弓形连杆和蟹行轴，蟹行轴与后车架转动连接，数量为两根分布于后车架的两侧，两根蟹行轴分别通过阶梯连杆连接弓形连杆的端部，弓形连杆的弧形部设于两根蟹行轴之间，还包括蟹行油缸，蟹行油缸用于驱动弓形连杆相对后车架左右移动，从而带动前车架左右移动形成前车架和后车架蟹行移动。弓形连杆的两端分别通过转向油缸连接前车架，转向油缸用于驱动前车架转向。还包括转向轴、摇摆轴和摇摆架。对压路机铰接蟹行机构的结构优化，使得整套蟹行机构的长度大幅缩短，且避免蟹行过程中蟹行对转向角度的干扰，实现蟹行状态下完整的转向角度。
