Recently, it was learned from the Hualing Technology Center that Valin's “Heavy-duty Truck Dual-lever Speed ​​Control Device†was authorized by the State Intellectual Property Office; Hua Ling Axle’s “Car Brakes with Spherical Bearings†and “Drive Axle "Inter-axle differential forced lubrication device" obtained a utility model patent; "Downward-opening external handle" obtained a design patent.
It is reported that the characteristics of the Hualing heavy-duty double-shift transmission operating device is that the long shaft is mounted on the longitudinal beam near the pivot shaft portion of the cab and the long shaft is hinged on the long shaft to shift the long arm and the following arm. Under the selected gears, the long rocker arms are relayed, and brackets are respectively installed on the left sidemembers, and the vertical forward and rearward shift relay rocker arms and the horizontal selectable relay rocker arms are respectively hinged with the pin shaft; and the short arm is selected at the handle. Between the lower end of the relay and the upper end of the relay, and between the lower end of the following relay and the front end of the selector rocker, and between the rear end of the selector rocker and the transmission. The selector links are respectively hingedly connected between the selector arms; between the lower end of the shifter short arm of the handle and the upper end of the upper swing arm of the upper shifter, and the lower end and the front shifter of the long swing arm following the lower shifter are Between the upper end of the rocker arm and between the upper end of the relay arm of the rear shifter and the shift arm of the transmission, the shifting link is hinged respectively, so that the shift gear is selected to be reliable, comfortable and efficient.
Automotive brake equipped with a spherical plain bearing: The purpose of this utility model is to provide an automobile brake equipped with a spherical plain bearing. The camshaft hole and the camshaft bracket on the bottom plate of the brake are jointed with the camshaft and the camshaft is used. When moving, the joint bearing can move freely with the camshaft, and the camshaft rotates smoothly without catching, thereby increasing the service life of the brake and making the car safer.
Drive axle differential forcibly lubricated between axle drives: The purpose of this utility model is to provide a forced lubrication device for axle differentials of axles of vehicles, which can effectively improve the lubrication conditions of differentials between axles and reduce and prevent differential speeds. The phenomenon of abrasion, ablation, and even burn-in of planetary gears, spiders, and bevel gears in the device prolongs the service life of the differential between shafts and reduces production costs.
