The invention provides a sanitation vehicle with a small turning radius. The sanitation vehicle with the small turning radius comprises a vehicle head provided with a steering system and a driving system, the vehicle head is connected with a compartment through a connecting mechanism, and the sanitation vehicle is characterized in that the connecting mechanism comprises a main frame fixedly connected with the vehicle head and an auxiliary frame fixedly connected with the compartment, and a vertical rotating shaft is arranged at the rear end of the main frame; a through hole is formed in the front end of the auxiliary frame, and the rotating shaft is sleeved with the through hole, so that the auxiliary frame can rotate relative to the main frame; an arc-shaped gear part is arranged at the front end of the auxiliary frame, a steering auxiliary motor is further installed on the main frame, a gear is arranged on the periphery of a motor shaft of the steering auxiliary motor, and the gear is meshed with the gear part of the auxiliary frame. The steering auxiliary motor is connected with an angle sensor used for detecting the rotating angle of a steering wheel. The connecting mechanism not only can realize the connection between the vehicle head and the carriage, but also can form a certain included angle between the carriage and the vehicle head during turning, so that the turning radius is reduced, and the sanitation vehicle can conveniently run on narrow road conditions.
本发明提出了一种转弯半径小的环卫车,包括具有转向系统和驱动系统的车头,所述车头通过连接机构与车厢连接,关键在于,所述连接机构包括与车头固定连接的主架、以及与车厢固定连接的副架,所述主架的后端设有垂直转轴,所述副架的前端设有通孔,所述通孔套设于转轴上,以使副架能够相对于主架转动;所述副架的前端设有弧形的齿轮部,所述主架上还安装有转向辅助电机,所述转向辅助电机的电机轴的外周设有齿轮,所述齿轮与副架的齿轮部啮合;所述转向辅助电机与用于检测方向盘转动角度的角度传感器相连。上述连接机构不仅可以实现车头与车厢的连接,还能够在转弯时使车厢与车头之间出现一定的夹角,以减少转弯半径,方便环卫车在狭窄路况行驶。
