Chassis dynamometer device for automatically fastening light vehicle and using method thereof

Abstract

The invention discloses a chassis dynamometer device for automatically fastening a light vehicle and a using method thereof. The chassis dynamometer device comprises a connecting assembly, a rotating assembly, a lifting assembly and a winding assembly, the connecting assembly comprises a mounting base, a guide rail, an arc-shaped cover, a lifting device connecting plate, a connecting table and a mounting hole, the connecting table is arranged at the center of the top of the mounting base, the top of the connecting table is fixedly connected with one side of the center of the bottom of the lifting device connecting plate through a bolt, and one side of the top of the lifting device connecting plate is fixedly connected with the bottom end of a lead screw lifter in the lifting assembly through a screw. A motor is used to winding and releasing a traction rope, the automatic winding and releasing of the traction rope are facilitated, the angle of a retractor during fastening is convenient to adjust through rotary connection of the connecting shaft and the arc-shaped cover, the height of the retractor during fastening is convenient to adjust through matched connection of the inner wall of the cylinder and the guide rail and the lead screw connecting block fixed to the cylinder, and the experiment efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of chassis dynamometers, in particular to a device for automatically fastening a light vehicle by a chassis dynamometer and a method for using the same. Background technique [0002] Chassis The chassis dynamometer is a special measurement device used to measure the output power, torque and speed of the driving wheel of the car. Some chassis dynamometers can also measure the acceleration performance and sliding performance of the car. In the laboratory, before the vehicle is tested by the chassis dynamometer, the vehicle needs to be towed to a suitable position, four traction devices are placed around the vehicle to be tested, and the vehicle under test and the traction device are connected by a traction rope. The technical traction rope cannot be retracted automatically, which increases the preparation time for the experiment and the equipment processing time after the experiment, and reduces the efficiency...

Problems solved by technology

In the laboratory, before the chassis dynamometer detects the vehicle, the vehicle needs to be towed to a suitable position, four traction devices are placed around the tested vehicle, and the tested vehicle and the traction device are connected by a traction rope. The technical traction rope cannot be retracted automatically, resulting in an increase in the preparation time for the experiment and the time for equipment processing after the experiment, which reduces the efficiency of the experiment
