Double guide rail glass regulator with equal lifting angular velocity

Abstract

The invention discloses a double guide rail glass lifter with equal lifting angular velocity, which includes a lifting motor, the lifting motor includes a motor wheel, and the motor wheel is sequentially connected to the lower pulley at the front end of the glass and the sliding block at the front end of the glass through a first transmission rope. , the glass front slider is sequentially connected to the glass front upper pulley, the glass rear lower pulley and the glass rear slider through the second transmission rope, and the glass rear slider is sequentially connected to the glass rear through the third transmission rope. The upper pulley and the motor wheel, the upper pulley at the rear end of the glass and the lower pulley at the rear end of the glass are variable transmission ratio pulleys with equal transmission ratios, and the angular speeds of the front end slider of the glass and the slider at the rear end of the glass are equal. The sliding blocks at the front and rear ends of the glass of the present invention can reach the upper and lower dead centers at the same time, which improves the sealing performance of the lifting glass and reduces the abnormal sound of the lifting glass.

Description

technical field [0001] The invention relates to the technical field of auto parts control, in particular to a double guide rail glass regulator with equal lifting angular velocities. Background technique [0002] At present, the structure of the double guide rail glass regulator adopts the transmission wheel with a fixed transmission ratio, which ensures that the lifting line speed on the front and rear guide rails is equal, but the length of the lifting line of the front and rear guide rails of the glass is different, so it will inevitably lead to glass failure. During the lifting process, one end is lifted to the dead point, and the other end is still far away from the dead point. Therefore, it is impossible to guarantee that the running trajectory of the glass conforms to the theoretical model, which in turn affects the performance of the vehicle such as sealing and abnormal noise. [0003] In the existing actual design process, this part of the theoretical gap differenc...
