The application discloses a novel electric trailer, which comprises a frame, a pair of front steering wheels and a pair of rear driving wheels arranged at the bottom of the frame, a pair of rear supporting rods arranged at the rear end of the frame, a same transmission shaft horizontally arranged and capable of rotating on the rear supporting rods and fixed at the lower ends of the two rear supporting rods, two rear driving wheels fixed at the two ends of the transmission shaft, a motor vertically arranged on the transmission shaft, a worm fixed on the output end of the motor and a worm wheel engaged with the worm fixed on the transmission shaft, a plurality of ball bearings arranged on the transmission shaft and a mounting hole formed in the rear supporting rod, and a waterproof cover, a battery and a control module modularly mounted on the transmission shaft and the rear supporting rod through the ball bearings and the mounting hole, wherein the waterproof cover entirely wraps the motor, the worm wheel and the worm, and the novel electric trailer has the advantages of compact structure, reasonable arrangement and convenient disassembly and assembly.

According to the brake for the transmission, when the brake is used, abrasion and noise caused by relative movement between the intermediate shaft serving as a rotating part and the piston of the brake do not exist, and compared with the prior art, noise pollution is reduced. In addition, due to the fact that the installation positions of the dual discs are optimized, the intermediate shaft can be designed to be of a hollow structure, the overall mass is reduced, meanwhile, the structure of a brake piston is simplified, the effect of reducing the machining and manufacturing difficulty is achieved, and the brake piston is suitable for large-scale application and popularization in the industry.

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 discloses an interior panel and a rail vehicle, applied to rail vehicle vibration absorption technology. The interior panel includes an interior panel body, a plurality of vibration absorbers disposed on the surface of the interior panel body, and a limiting component. The vibration absorbers are spaced apart, and each vibration absorber includes an elastic layer component and a mass layer component. The elastic layer component is located between the interior panel body and the mass layer component. The limiting component covers the side of the mass layer component opposite to the interior panel body and is fixed to the surface of the interior panel body. The interior panel provided by this utility model can improve the low-frequency sound insulation of the rail vehicle body, reduce interior noise, and improve comfort. Due to the structure of the interior panel body, it is easy to operate, saves space, and allows for flexible arrangement.

This utility model provides a support architecture for a machine room-less elevator main drive system, solving the problems of unreasonable traction machine placement, large space occupation, and inconvenient construction in existing machine room-less elevator main drive systems. The technical solution is as follows: the main drive beam includes a rope head beam rear side plate and a rope head beam front side plate, which are supported side-by-side between the main guide rail and the counterweight guide rail. The traction machine base is fixed to the rear side of the main guide rail with bolts, and the traction machine base is equipped with shock-absorbing rubber pads and bolts for fixing to the bottom of the traction machine. A connecting bend plate is fixed to the connection between the main guide rail and the rope head beam rear side plate with bolts. The connecting bend plate is equipped with a traction machine shock-absorbing and stabilizing frame, which is composed of a sleeve-type lower connecting bracket and a sleeve-type upper connecting bracket connected together. An elastic rubber sleeve is provided between the lower and upper connecting brackets. This optimizes the traction machine installation position, increases traction machine stability, reduces space occupation on the top floor, facilitates construction, and enhances the elevator's adaptability.
