AI Technical Summary

Technical Problem

Existing stabilizer bar disconnectors can easily cause the stabilizer bar to move laterally when the vehicle is out of trouble, causing the vehicle to lose balance. It is also difficult to ensure that the transmission gear hub is accurately docked during resetting, posing a safety hazard.

Method used

A positioning transmission mechanism for the disconnector on the stabilizer bar is designed. The combination of a transmission sleeve, a transmission gear hub, a guide column and a return spring ensures the stability of the transmission sleeve axis. The asymmetric parallel and missing tooth structure limits the engagement angle of the transmission gear hub, allowing the stabilizer bar to accurately return to its original position when disconnecting and engaging.

Benefits of technology

It effectively avoids axial misalignment of the stabilizer bar during the process of disconnection and engagement, ensures that the vehicle remains balanced when getting out of trouble, and can be accurately docked when resetting, thereby improving the vehicle's driving stability and safety.

Abstract

The utility model discloses a positioning transmission mechanism of a breaker on a stabilizer bar, which belongs to the technical field of stabilizer bar breakers and is characterized in that transmission sleeves for connecting and transmitting two ends of the stabilizer bar are matched with each other in axis, and a spring matched with the transmission sleeves is overlapped with the axis in the sliding direction of the transmission sleeves. Transmission gear hubs are additionally arranged, a guide column is further clamped between the two transmission gear hubs, inner round holes of the transmission gear hubs are supported and guided through outer cylindrical surfaces of the guide column, and the situation that stabilizer bars on the two sides are transversely staggered is effectively avoided; according to the device, asymmetric parallel teeth and missing teeth are additionally arranged on meshing splines of the transmission sleeve, the transmission gear hub and the stabilizer bar, so that stable transmission can be kept when the transmission parts are in butt joint, each part can return to the original angle for positioning butt joint when the transmission parts are in meshing transmission again after separation, the stabilizer bar can finally return to the original position, and the service life of the stabilizer bar is prolonged. And the vehicle is kept balanced.
