5results about How to "Shift quickly" patented technology

This invention discloses a rapid detection device for the planar runout of the end face of medium and large bearings, comprising a base and a turntable. The top wall of the turntable serves as a placement surface, and several slots are evenly distributed along the circumference of the turntable on the placement surface. Each slot is formed from the edge of the turntable towards its center. A clamp is movably mounted in any three slots, arranged in a triangular pattern. Each clamp has an arc-shaped contact surface at its starting end for contacting the outer peripheral wall of the bearing race under test. Each clamp is equipped with a fastening structure for securely connecting the clamp to the corresponding slot and an adjustment structure for adjusting the relative height between the clamp and the turntable to accommodate bearing races of different thicknesses. The base is equipped with a detection element for detecting the planar runout of the bearing race end face. This invention solves the problems of existing bearing planar runout detection equipment, such as complex structure, poor adaptability, easy damage to the bearing surface, inconvenient disassembly and assembly, and low detection efficiency.

This utility model belongs to the field of new energy vehicle power transmission technology, and discloses a single-motor two-speed electric drive axle powertrain, including a disc motor, a reducer housing, a first shaft assembly, an intermediate shaft assembly, a reducer end cover, an axle housing, a first half-shaft, a differential, a second-stage reduction passive gear, a second half-shaft, a coupling sleeve, and a differential lock assembly. This solution achieves the advantages of compact structure, short axial dimension, and high power density by adopting an integrated design of an axial flux disc motor and a two-speed reduction mechanism, which is convenient for application in vehicles with high ground clearance requirements and limited installation space. By using a ball screw type shifting actuator in conjunction with motor speed adjustment, synchronizer-free rapid shifting is achieved, improving shifting smoothness and system reliability. The hollow intermediate shaft assembly and lubrication oil passage design make lubrication efficient and the structure simplified, improving operational reliability. The rear-mounted integrated differential lock assembly enhances the ability to get out of trouble in complex road conditions and the vehicle's adaptability.

This utility model relates to the field of quick manual gear shifting technology, and discloses a quick manual gear shifting mechanism, including a mounting plate, a support shaft, a shift fork shaft, a shift fork gear, a two-speed gear, and a shift drive assembly. The support shaft and the shift fork shaft are fixed to the mounting plate. The shift fork gear is slidably connected to the support shaft via a spline. The shift drive assembly includes a shift fork seat, a shift fork block, and a toothed shift fork, which is slidably connected to the shift fork shaft and is used to drive the shift fork gear to move axially, selectively engaging with the two-speed gear rotatably connected to the support shaft. The key feature is the inclusion of a self-locking positioning device. This device, through the cooperation of a groove on the shift fork shaft and a steel ball, mechanically locks the shift drive assembly after the gear is engaged, stably maintaining the engagement position. This utility model solves the problems of unstable engagement positioning and easy automatic disengagement due to vibration in existing gear shifting mechanisms, achieving the beneficial effects of quick shifting, accurate positioning, and stable and reliable engagement.
