Side brush mechanism for a tunnel type car washing machine

A side brush mechanism-with a novel structure, used for a tunnel type car washing machine, comprising:

• a side brush mounting beam, configured to be mounted on a tunnel type car washing machine;
• a side brush assembly for brushing left and right sides of a vehicle;
• a side brush swing arm with one end rotatably connected to the side brush mounting beam and another end rotatably connected to a reducer;
• the reducer in driving connection with the side brush assembly to drive the side brush assembly to rotate;
• a left-right skew actuator arranged between the side brush swing arm and the reducer and used for driving the reducer and the side brush assembly to swing leftwards and rightwards to adjust a brushing angle;
• and
• a rocker arm actuator with one end rotatably connected to the side brush swing arm and another end configured to be mounted on the tunnel type car washing machine to drive the side brush swing arm to swing horizontally left and right;
• wherein a vertical seat bearing is arranged at an end, away from the side brush mounting beam, of the side brush swing arm, the vertical seat bearing is connected to a left-right skew bracket through a left-right skew swing shaft, and the left-right skew bracket is rotatably connected to one end of the left-right skew actuator;
• and another end of the left-right skew actuator is rotatably connected to a left-right skew support on the reducer.
