Speed changing box braking device of snow throwing vehicle
The invention discloses a braking device for a speed changing box of a snow throwing vehicle, and relates to the technical field of snow removing equipment. The pneumatic brake comprises a brake disc and an air compression brake body, a pair of friction plates of the air compression brake body are arranged on the two sides of the brake disc, the brake disc is connected with an output flange of a gearbox through a connecting flange, the air compression brake body is connected with an air source through an air pipe, and a pneumatic electromagnetic valve is arranged on the air pipe to control on-off of an air path. A circuit of the pneumatic electromagnetic valve is controlled by a relay to be switched on and off; a coil of the relay is connected between a gearbox neutral gear switch and the ground, one end of a contact of the relay is connected with a power supply through a protector, the other end of the contact is connected with a circuit inlet of the pneumatic electromagnetic valve, and a circuit outlet of the pneumatic electromagnetic valve is grounded. Compared with the prior art, the problem that when the load of the output end of the gearbox of the snow throwing vehicle is very small, the output shaft rotates when the gearbox is in the neutral gear can be solved.
本发明公开了一种抛雪车变速箱制动装置，涉及除雪设备技术领域；它包括制动盘和空压制动器，所述空压制动器的一对摩擦片设在所述制动盘的两侧，所述制动盘通过连接法兰与变速箱的输出法兰相连接，所述空压制动器通过气管与气源相连接，所述气管上设有气动电磁阀控制气路的通断，所述气动电磁阀由继电器控制电路的通断；所述继电器的线圈连接在变速箱空挡开关和地之间，所述继电器的触点一端通过保险器与电源相连接，触点另一端与所述气动电磁阀的电路入口相连接，所述气动电磁阀的电路出口接地。与现有技术相比，本发明可以解决当抛雪车变速箱输出端负载很小时，存在变速箱空挡时输出轴转动的问题。
