Abstract

The invention discloses a hydraulic sliding table brake device for a vehicle sliding table test. The hydraulic sliding table brake device comprises a hydraulic cylinder and at least two piston parts, wherein the hydraulic cylinder is cuboid-shaped and comprises a top plate, a bottom plate, a front side plate, a rear side plate, a left side plate, a right side plate, a first sub-partition and a second sub-partition; the first sub-partition and the second sub-partition are connected in a cross shape; the hydraulic cylinder is equally divided into a plurality of piston cavities; the piston cavities are grouped in pairs; each group of piston cavities includes two piston cavities arranged in a length extending direction of the left side plate; at least one piston part is mounted in the group of piston cavities; an oil inlet is formed in the top plate; through holes in one-to-one correspondence with the piston parts are formed in the first sub-partition at intervals; each piston part comprises two pistons and a piston rod for connecting the pistons, the piston rod penetrates through the corresponding through hole in the first sub-partition, and the pistons are positioned in the piston cavities in the group of piston cavities and can penetrate through the front side plate and the rear side plate respectively. The hydraulic sliding table brake device can bidirectionally move and is high in response speed.

Description

technical field [0001] The invention relates to the technical field of automobile collision test, in particular to a hydraulic sliding table braking device for vehicle sliding table test. Background technique [0002] The development of the automobile industry has brought great convenience to people's lives and has become a major driving force and opportunity for the economic development of various countries. At the same time, automobiles also have a great negative impact on human society, which is the constant occurrence of traffic accidents, car exhaust that pollutes the environment and the energy crisis caused by automobile fuel. Among them, car safety is the most directly related to people's lives. Vehicle safety has a huge impact on the life safety of occupants and pedestrians outside the vehicle. The safety restraint system plays a key role in the safety of the vehicle, and the matching of the safety restraint system is usually completed in the sliding table system t...
