Description
Technical field
The utility model relates to technical field of automobile components, is specifically related to a kind of Steering gear with pooling feature.
Background technology
Steering gear is arranged on vehicle body, and its effect is the steering shaft, universal drive shaft etc. that support steering handwheel and be connected with steering handwheel, steering operation is passed to deflector.Steering column is very important parts in whole automobile steering system, main closure dish and deflector on car load, and in whole steering procedure, steering column plays the gearing that chaufeur rotates vehicle.All to be rigidly connected between existing turning member, and each other without damping part, at car once the comparatively serious collision of generation or extruding modification, concerning just more dangerous the personnel in operator's compartment.Bearing circle and steering column are come from for the injury of steering swivel system to people.The position that the personnel that cause injure concentrates on head, chest and leg.So the plastic deformation of steering system parts, elastic deformation and some parts are separated from each other and can not transmit motion and power or utilize the friction between parts to carry out apparatus with shock absorbing when taking measures to be collision.Therefore, how to make tubing string realize the requirement of crumple energy-absorbing, to protect occupant safety, propose requirement to the design of tubing string, meanwhile, in order to meet corresponding requirement, the structure design of tubing string each several part and type selecting are crucial.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of Steering gear with pooling feature, and steering column is reasonable in design, by the anterior modification pressure of energy-absorbing and compression solution compartment, buffering two aspects, finally reduces the injury to chaufeur.
Technical scheme
Technical problem to be solved in the utility model can be come to be realize by the following technical programs:
A kind of Steering gear with pooling feature, comprise steering shaft, changeable type support and rotation tween drive shaft, described rotation tween drive shaft is made up of axle sleeve and piston rod, piston-rod lower end inserts in axle sleeve, piston-rod lower end is provided with piston ring, piston rod upper end connects upper axle by joint coupling, upper axle upper end cover has Upper shaft sleeve, relief spring is provided with between upper axle and Upper shaft sleeve, described Upper shaft sleeve overcoat has steering column jacket, steering shaft is inserted with in steering column jacket, steering shaft upper end connection of rotating dish, described changeable type support is placed on steering column jacket outer wall, fixed by bearing between steering shaft and steering column jacket.
Described rotation tween drive shaft axle sleeve lower end connects deflector.
Be provided with regulating mechanism outside described Upper shaft sleeve, regulating mechanism front end connects changeable type support.
Described regulating mechanism comprises adapter plate and telescopic supporting rod, and telescopic supporting rod lower end is hingedly coupled on adapter plate, is fixed as and is distributed in telescopic supporting rod both sides for a pair, and telescopic supporting rod front end connects changeable type support.
Compared with prior art, the beneficial effects of the utility model are:
The utility model steering shaft is divided into two sections of parts, connected by universal connecting components between two sections of parts, wherein two sections of parts are respectively equipped with the energy absorption device of air cylinder structure and the buffer structure of spring structure, by the anterior modification pressure of energy-absorbing and compression solution compartment, buffering two aspects, finally reduce the injury to chaufeur.
